Significant Accounting Policies [Text Block]	'
	Note 1 – Significant Accounting Policies
	Principles of consolidation: All majority-owned subsidiaries are included in the Company's consolidated financial statements, with appropriate elimination of intercompany balances and transactions. Investments in associated companies (less than majority-owned and in which the Company has significant influence) are accounted for under the equity method. The Company's share of net income or losses in these investments in associated companies is included in the Consolidated Statement of Income. The Company periodically reviews these investments for impairments and, if necessary, would adjust these investments to their fair value when a decline in market value or other impairment indicators are deemed to be other than temporary.
	The Financial Accounting Standards Board's (“FASB's”) guidance regarding the consolidation of certain Variable Interest Entities (“VIEs”) generally requires that assets, liabilities and results of the activities of a VIE be consolidated into the financial statements of the enterprise that is considered the primary beneficiary. The consolidated financial statements include the accounts of the Company and all of its subsidiaries in which a controlling interest is maintained and would include any VIEs if the Company was the primary beneficiary pursuant to the provisions of the applicable guidance.
	Translation of foreign currency: Assets and liabilities of non-U.S. subsidiaries and associated companies are translated into U.S. Dollars at the respective rates of exchange prevailing at the end of the year. Income and expense accounts are translated at average exchange rates prevailing during the year. Translation adjustments resulting from this process are recorded directly in equity as accumulated other comprehensive income (loss) and will be included as income or expense only upon sale or liquidation of the underlying investment. All non-U.S. subsidiaries use their local currency as their functional currency.
	Cash and cash equivalents: The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents.
	Inventories: Inventories are valued at the lower of cost or market value, and are valued using the first-in, first-out (“FIFO”) method. See also Note 9 of Notes to Consolidated Financial Statements.
	Long-lived assets: Property, plant and equipment are stated at cost. Depreciation is computed using the straight-line method on an individual asset basis over the following estimated useful lives: buildings and improvements, 10 to 45 years; and machinery and equipment, 1 to 15 years. The carrying value of long-lived assets is periodically evaluated whenever changes in circumstances or current events indicate the carrying amount of such assets may not be recoverable. An estimate of undiscounted cash flows produced by the asset, or the appropriate group of assets, is compared with the carrying value to determine whether an impairment exists. If necessary, the Company recognizes an impairment loss for the difference between the carrying amount of the assets and their estimated fair value. Fair value is based on current and anticipated future undiscounted cash flows. Upon sale or other dispositions of long-lived assets, the applicable amounts of asset cost and accumulated depreciation are removed from the accounts and the net amount, less proceeds from disposals, is recorded in income. Expenditures for renewals or improvements that increase the estimated useful life or capacity of the assets are capitalized, whereas expenditures for repairs and maintenance are expensed when incurred.
	Capitalized software: The Company capitalizes certain costs incurred in connection with developing or obtaining software for internal use. These costs are amortized over a period of three to five years once the assets are ready for their intended use. In connection with the implementations and upgrades to the Company's global transaction, consolidation and other related systems, approximately $1,198 and $2,395 of net costs were capitalized in property, plant and equipment on the Company's December 31, 2013 and December 31, 2012 Consolidated Balance Sheets, respectively.
	Goodwill and other intangible assets: The Company records goodwill, definite-lived intangible assets and indefinite-lived intangible assets at fair value at the date of acquisition. Goodwill and indefinite-lived intangible assets are not amortized, but tested for impairment at least annually. These tests will be performed more frequently if triggering events indicate potential impairment. Definite-lived intangible assets are amortized over their estimated useful lives, generally for periods ranging from 5 to 20 years. The Company continually evaluates the reasonableness of the useful lives of these assets, consistent with the discussion of long-lived assets, above. See Note 11 of Notes to Consolidated Financial Statements.
	Revenue recognition: The Company recognizes revenue in accordance with the terms of the underlying agreements, when title and risk of loss have been transferred, when collectability is reasonably assured, and when pricing is fixed or determinable. This generally occurs when products are shipped to customers or, for consignment-type arrangements, upon usage by the customer and when services are performed. License fees and royalties are included in other income when recognized in accordance with their agreed-upon terms, when performance obligations are satisfied, when the amount is fixed or determinable, and when collectability is reasonably assured. As part of the Company's chemical management services, certain third-party product sales to customers are managed by the Company. Where the Company acts as a principal, revenues are recognized on a gross reporting basis at the selling price negotiated with its customers. Where the Company acts as an agent, such revenue is recorded using net reporting as service revenue at the amount of the administrative fee earned by the Company for ordering the goods. Third-party products transferred under arrangements resulting in net reporting totaled $41,553, $39,299 and $50,893 for 2013, 2012 and 2011, respectively.
	Accounts receivable and allowance for doubtful accounts: Trade accounts receivable are recorded at the invoiced amount and generally do not bear interest. The allowance for doubtful accounts is the Company's best estimate of the amount of probable credit losses with its existing accounts receivable. Reserves for customers filing for bankruptcy protection are generally established at 75-100% of the amount owed at the filing date, dependent on the Company's evaluation of likely proceeds from the bankruptcy process. Large and/or financially distressed customers are generally reserved for on a specific review basis while a general reserve is established for other customers based on historical experience. The Company performs a formal review of its allowance for doubtful accounts quarterly. Account balances are charged off against the allowance when the Company feels it is probable the receivable will not be recovered. The Company does not have any off-balance-sheet credit exposure related to its customers. During 2013, the Company's five largest customers accounted for approximately 18% of its consolidated net sales with the largest customer (Arcelor-Mittal Group) accounting for approximately 9% of the Company's consolidated net sales.
	During 2012, the Company recorded charges of $1,254 to its allowance for doubtful accounts and selling, general and administrative expenses (“SG&A”) due to the bankruptcies of two U.S. customers. See Note 8 of Notes to Consolidated Financial Statements.
	Research and development costs: Research and development costs are expensed as incurred and are included in SG&A. Research and development expenses were $21,578, $19,993 and $18,812 in 2013, 2012 and 2011, respectively.
	Concentration of credit risk: Financial instruments, which potentially subject the Company to a concentration of credit risk, principally consist of cash equivalents, short-term investments and trade receivables. The Company invests temporary and excess funds in money market securities and financial instruments having maturities typically within 90 days. The Company has not experienced losses from the aforementioned investments.
	Environmental liabilities and expenditures: Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. If there is a range of estimated liability and no amount in that range is considered more probable than another, then the Company records the lowest amount in the range in accordance with generally accepted accounting principles. Accrued liabilities are exclusive of claims against third parties and are not discounted. Environmental costs and remediation costs are capitalized if the costs extend the life, increase the capacity or improve safety or efficiency of the property from the date acquired or constructed, and/or mitigate or prevent contamination in the future.
	Asset retirement obligations: The Company follows the FASB's guidance regarding asset retirement obligations, which addresses the accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated retirement costs. Also, the Company follows the FASB's guidance for conditional asset retirement obligations (“CARO”), which relates to legal obligations to perform an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event that may or may not be within the control of the entity. In accordance with this guidance, the Company records a liability when there is enough information regarding the timing of the CARO to perform a probability-weighted discounted cash flow analysis. At December 31, 2013 and December 31, 2012, the Company had limited exposure to such obligations and had immaterial liabilities recorded for such on its Consolidated Balance Sheets.
	Pension and other postretirement benefits: The Company maintains various noncontributory retirement plans, the largest of which is in the U.S., covering substantially all of its employees in the U.S. and certain other countries. The plans of the Company's subsidiaries in The Netherlands, the United Kingdom and Mexico are subject to the provisions of FASB's guidance regarding employers' accounting for defined benefit pension plans. The plans of the remaining non-U.S. subsidiaries are, for the most part, either fully insured or integrated with the local governments' plans and are not subject to the provisions of the guidance. The guidance requires that employers recognize on a prospective basis the funded status of their defined benefit pension and other postretirement plans on their consolidated balance sheet and, also, recognize as a component of other comprehensive income, net of tax, the gains or losses and prior service costs or credits that arise during the period but are not recognized as components of net periodic benefit cost. The Company's U.S. pension plan year ends on November 30 and the measurement date is December 31. The measurement date for the Company's other postretirement benefits plan is December 31.
	The Company's pension investment policy is designed to ensure that pension assets are invested in a manner consistent with meeting the future benefit obligations of the pension plans and maintaining compliance with various laws and regulations including the Employee Retirement Income Security Act of 1974 (“ERISA”). The Company establishes strategic asset allocation percentage targets and appropriate benchmarks for significant asset classes with the aim of achieving a prudent balance between return and risk. The Company's investment horizon is generally long term, and, accordingly, the target asset allocations encompass a long-term perspective of capital markets, expected risk and return and perceived future economic conditions while also considering the profile of plan liabilities. To the extent feasible, the short-term investment portfolio is managed to immunize the short-term obligations, the intermediate portfolio duration is immunized to reduce the risk of volatility in intermediate plan distributions, and the total return portfolio is expected to maximize the long-term real growth of plan assets. The critical investment principles of diversification, assessment of risk and targeting the optimal expected returns for given levels of risk are applied. The Company's investment guidelines prohibit use of securities such as letter stock and other unregistered securities, commodities or commodity contracts, short sales, margin transactions, private placements (unless specifically addressed by addendum), or any derivatives, options or futures for the purpose of portfolio leveraging.
	The target asset allocation is reviewed periodically and is determined based on a long-term projection of capital market outcomes, inflation rates, fixed income yields, returns, volatilities and correlation relationships. The interaction between plan assets and benefit obligations is periodically studied to assist in establishing such strategic asset allocation targets. Asset performance is monitored with an overall expectation that plan assets will meet or exceed benchmark performance over rolling five-year periods. The Company's pension committee, as authorized by the Company's Board of Directors, has discretion to manage the assets within established asset allocation ranges approved by senior management of the Company. As of December 31, 2013, the plan's investments were in compliance with all approved ranges of asset allocations. See Note 16 of Notes to Consolidated Financial Statements.
	Comprehensive income (loss): The Company presents other comprehensive income (loss) in its Statement of Comprehensive Income. During 2013, the Company adopted the FASB's guidance regarding the disclosure of reclassifications from Accumulated Other Comprehensive Income (Loss) (“AOCI”). The guidance requires the disclosure of significant amounts reclassified from each component of AOCI, the related tax amounts and the income statement line items affected by the reclassifications, either parenthetically on the Consolidated Statement of Comprehensive Income or in the Notes to the Consolidated Financial Statements. The Company elected to present the information in the Notes to the Consolidated Financial Statements, and the adoption of this guidance did not have a material impact on the Company's results or financial condition. See Note 18 of Notes to Consolidated Financial Statements.
	Income taxes and uncertain tax positions: The provision for income taxes is determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes represents income taxes paid or payable for the current year and the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax bases of the Company's assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. The FASB's guidance regarding accounting for uncertainty in income taxes prescribes the recognition threshold and measurement attributes for financial statement recognition and measurement of tax positions taken or expected to be taken on a tax return. The guidance further requires the determination of whether the benefits of tax positions will be more likely than not sustained upon audit based upon the technical merits of the tax position. For tax positions that are determined to be more likely than not sustained upon audit, a company recognizes the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement in the financial statements. For tax positions that are not determined to be more likely than not sustained upon audit, a company does not recognize any portion of the benefit in the financial statements. Additionally, the guidance provides for derecognition, classification, penalties and interest, accounting in interim periods, disclosure and transition. The guidance also requires that the amount of interest expense and income to be recognized related to uncertain tax positions be computed by applying the applicable statutory rate of interest to the difference between the tax position recognized, including timing differences, and the amount previously taken or expected to be taken in a tax return. The Company's continuing practice is to recognize interest and/or penalties related to income tax matters in income tax expense. During 2013, the Company adopted guidance that requires an entity to net its liability for unrecognized tax benefits against deferred tax assets related to net operating losses or other tax credit carryforwards that would apply if the uncertain tax position were settled for the presumed amount at the balance sheet date, which had an immaterial impact on the Company's current year results and financial condition. See Note 6 of Notes to Consolidated Financial Statements.
	Derivatives: The Company is exposed to the impact of changes in interest rates, foreign currency fluctuations, changes in commodity prices and credit risk. The Company is currently not using derivative instruments to mitigate the risks associated with foreign currency fluctuations, changes in commodity prices or credit risk, but has used derivative financial instruments primarily for purposes of hedging exposures to fluctuations in interest rates in the past. The Company recognized all derivatives on its balance sheet at fair value. For derivative instruments designated as cash flow hedges, the effective portion of any hedge would be reported in Accumulated Other Comprehensive Income (Loss) until it was cleared to earnings during the same period in which the hedged item affected earnings. The Company currently uses no derivative instruments designated as fair value hedges and has not entered into derivative contracts for trading or speculative purposes. See Note 21 of Notes to Consolidated Financial Statements.
	Fair value measurements: The Company utilizes the FASB's guidance regarding fair value measurements, which establishes a common definition for fair value to be applied to guidance requiring use of fair value, establishes a framework for measuring fair value and expands disclosure about such fair value measurements. Specifically, the guidance utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels:
		•	Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities.
		•	Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.
		•	Level 3: Unobservable inputs that reflect the reporting entity's own assumptions.
	Stock-based compensation: The Company applies the FASB's guidance regarding share-based payments, which requires the recognition of the fair value of stock-based compensation as a component of expense. The Company has a long-term incentive program (“LTIP”) for key employees which provides for the granting of options to purchase stock at prices not less than its market value on the date of the grant. Most options become exercisable between one and three years after the date of the grant for a period of time determined by the Company, but not to exceed seven years from the date of grant. Common stock awards and Restricted Stock Units (“RSU”) issued under the LTIP program are subject only to time vesting over a three to five-year period. In addition, as part of the Company's Global Annual Incentive Plan (“GAIP”), nonvested shares may be issued to key employees, which generally vest over a two to five-year period. Based on historical experience, the Company has generally assumed a forfeiture rate of 13% on its nonvested stock awards. The Company will record additional expense if the actual forfeiture rate is lower than estimated, and will record a recovery of prior expense if the actual forfeiture is higher than estimated. See Note 4 of Notes to Consolidated Financial Statements.
	Earnings per share: The Company follows FASB's guidance regarding the calculation of earnings per share (“EPS”) for nonvested stock awards with rights to non-forfeitable dividends. The guidance requires nonvested stock awards with rights to non-forfeitable dividends to be included as part of the basic weighted average share calculation under the two-class method. See Note 7 of Notes to Consolidated Financial Statements.
	Segments: The Company's reportable operating segments evidence the structure of the Company's internal organization, the method by which the Company's resources are allocated and the manner by which the Company assesses its performance. During 2013, certain internal shifts in the Company's management and changes to the structure of internally reported information occurred. The Company currently believes its structure, its resource allocation and its performance assessment are now more closely aligned with its four geographical regions: the North America region, the Europe, Middle East and Africa (“EMEA”) region, the Asia/Pacific region and the South America region. Therefore, the Company changed its reportable operating segments from those categorized by product nature to those organized by geography. All prior period information has been recast to reflect these four regions as the Company's new reportable operating segments. See Note 3 of Notes to Consolidated Financial Statements.
	Reclassifications: Certain information has been reclassified to conform to the current year presentation.
	Accounting estimates: The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and disclosure of contingencies at the date of the financial statements and the reported amounts of net sales and expenses during the reporting period. Actual results could differ from such estimates.

	Note 2 – Out-of-Period Adjustment
	As previously disclosed in the Company's 2012 Annual Report on Form 10-K, the Company had reassessed its ability to significantly influence the operating and financial policies of its captive insurance equity affiliate, Primex. Based on its ownership percentage and other factors, the Company determined that, during 2012, the Company obtained the ability to significantly influence Primex and, as a result, changed its method of accounting from the cost to equity method. During the first quarter of 2013, the Company identified errors in Primex's estimated 2012 financial statements, which primarily related to a reinsurance contract held by Primex. The identified errors resulted in a cumulative $1,038 understatement of the Company's equity in net income from associated companies for the year ended December 31, 2012. The Company corrected the errors related to Primex in the first quarter of 2013, which had the net effect of increasing equity in net income from associated companies by $1,038 for the three months ended March 31, 2013 and the year ended December 31, 2013. The Company does not believe this adjustment is material to its consolidated financial statements for the year ended December 31, 2012 or to the Company's results for the year ended December 31, 2013 and, therefore, did not restate any prior period amounts.

	The Company's reportable operating segments evidence the structure of the Company's internal organization, the method by which the Company's resources are allocated and the manner by which the Company assesses its performance. During 2013, certain internal shifts in the Company's management and changes to the structure of internally reported information occurred. The Company currently believes its structure, its resource allocation and its performance assessment are now more closely aligned with its four geographical regions: North America, EMEA, Asia/Pacific and South America. Therefore, the Company changed its reportable operating segments from those categorized by product nature to those organized by geography. All prior period information has been recast to reflect these four regions as the Company's new reportable operating segments.
	Though the Company changed its reportable operating segments in the third quarter of 2013, the calculation of the reportable segment's measure of earnings remains relatively consistent with past practices. Operating earnings, excluding indirect operating expenses, for the Company's reportable segments are comprised of revenues less costs of goods sold and SG&A directly related to the respective regions' product sales. The Company's indirect operating expenses consist of SG&A related expenses that are not directly attributable to the product sales of each respective reporting segment. Other items not specifically identified with the Company's reportable operating segments include interest expense, interest income, license fees from non-consolidated affiliates and other income (expense).
	The following tables present information about the performance of the Company's reportable operating segments for the years ended December 31, 2013, December 31, 2012 and December 31, 2011:

	As of December 31, 2013, unrecognized compensation expense related to options granted in 2011 was $24, for options granted during 2012 was $240 and for options granted in 2013 was $464.
	Consistent with prior years, the Company granted stock options under its LTIP plan that are subject only to time vesting over a three-year period in the first quarters of 2010, 2011, 2012 and 2013. Also, in connection with a transition of key employees in the Company during the second quarter of 2012, stock options were granted that are also subject only to time vesting over a three-year period. For the purposes of determining the fair value of stock option awards, the Company uses the Black-Scholes option pricing model and the assumptions set forth in the table below:
				For the Year Ended December 31,										June 30,
				2013			2012			2011		2010		2012
		Stock option awards		29,302			37,965			36,835		110,939		2,192
		Dividend yield		2.49	%		3.09	%		5	%	5.1	%	2.69	%
		Expected volatility		57.28	%		69.9	%		62.13	%	53.72	%	69.09	%
		Risk-free interest rate		0.63	%		0.61	%		1.99	%	2.85	%	0.58	%
		Expected term (years)		4			4			5		6		4
	These awards are being amortized on a straight-line basis over the respective vesting period of each award. The compensation expense recorded on each award during 2013, 2012 and 2011, respectively, is as follows:
				Year Ended December 31,
				2013			2012			2011
		2013 Stock option awards	$	174		$	0		$	0
		2012 Stock option awards	$	189		$	167		$	0
		2011 Stock option awards	$	138		$	164		$	139
		2010 Stock option awards	$	16		$	193		$	224
	Activity of nonvested shares granted under the Company's LTIP plan is shown below:
					Weighted
					Average Grant
			Number of		Date Fair Value
			Shares		(per share)
		Nonvested awards, December 31, 2012	122,944		$	31.98
		Granted	51,659		$	61.56
		Vested	-51,981		$	26.02
		Forfeited	-6,638		$	41.7
	Nonvested awards, December 31, 2013	115,984		$	47.27
The fair value of the nonvested stock is based on the trading price of the Company's common stock on the date of grant. The Company adjusts the grant date fair value for expected forfeitures based on historical experience for similar awards. As of December 31, 2013, unrecognized compensation expense related to these awards was $2,772, to be recognized over a weighted average remaining period of 2.32 years.
Activity of nonvested restricted stock units granted under the Company's LTIP plan is shown below:
				Weighted
				Average Grant
		Number of		Date Fair Value
		Units		(per unit)
	Nonvested awards, December 31, 2012	2,100		$	38.13
	Granted	1,918		$	62.39
	Nonvested awards, December 31, 2013	4,018		$	49.71
The fair value of the nonvested restricted stock units is based on the trading price of the Company's common stock on the date of grant. The Company adjusts the grant date fair value for expected forfeitures based on historical experience for similar awards. As of December 31, 2013, unrecognized compensation expense related to these awards was $114 to be recognized over a weighted average remaining period of 2.16 years.
Employee Stock Purchase Plan
In 2000, the Board adopted an Employee Stock Purchase Plan (“ESPP”) whereby employees may purchase Company stock through a payroll deduction plan. Purchases are made from the plan and credited to each participant's account at the end of each month, the “Investment Date.” The purchase price of the stock is 85% of the fair market value on the Investment Date. The plan is compensatory and the 15% discount is expensed on the Investment Date. All employees, including officers, are eligible to participate in this plan. A participant may withdraw all uninvested payment balances credited to a participant's account at any time. An employee whose stock ownership of the Company exceeds five percent of the outstanding common stock is not eligible to participate in this plan.
2013 Director Stock Ownership Plan
In March 2013, the Company adopted the 2013 Director Stock Ownership Plan (the “Plan”), subject to the approval by the Company's shareholders at the annual meeting, to encourage the Directors to increase their investment in the Company. The Plan was approved at the Company's May 2013 shareholders' meeting. The Plan authorizes the issuance of up to 75,000 shares of Quaker common stock in accordance with the terms of the Plan in payment of all or a portion of the annual cash retainer payable to each of the Company's non-employee directors in 2013 and subsequent years during the term of the Plan. Under the Plan, each director who, on May 1st of the applicable calendar year, owns less than 400% of the annual cash retainer for the applicable calendar year, divided by the average of the closing price of a share of Quaker Common Stock as reported by the composite tape of the New York Stock Exchange for the previous calendar year (the “Threshold Amount”), is required to receive 75% of the annual cash retainer in Quaker common stock and 25% of the retainer in cash, unless the director elects to receive a greater percentage of Quaker common stock (up to 100%) of the annual cash retainer for the applicable year. Each director who owns more than the Threshold Amount may elect to receive common stock in payment of a percentage (up to 100%) of the annual cash retainer. The annual retainer is $50 and the retainer payment date is June 1. The Plan was adopted in order to replace the 2003 Director Stock Ownership Plan, which expired in May 2013.

At December 31, 2013, the Company domestically had a net deferred tax asset of $12,695. In addition, the Company has foreign tax loss carryforwards of $12,160 of which $15 expires in 2014, $352 expires in 2015, $119 expires in 2016, $344 expires in 2017, $619 expires in 2018, $291 expires in 2019, $102 expires in 2020, $245 expires in 2021 and $258 expires in 2022; the remaining foreign tax losses have no expiration dates. A partial valuation allowance has been established with respect to the tax benefit of these losses for $2,104.
U.S. income taxes have not been provided on the undistributed earnings of non-U.S. subsidiaries because it is the Company's intention to continue to reinvest these earnings in those subsidiaries to support growth initiatives. U.S. and foreign income taxes that would be payable if such earnings were distributed may be lower than the amount computed at the U.S. statutory rate due to the availability of tax credits. The amount of such undistributed earnings at December 31, 2013 was approximately $188,000. Any income tax liability, which might result from ultimate remittance of these earnings, is expected to be substantially offset by foreign tax credits. It is currently impractical to estimate any such incremental tax expense.
As of December 31, 2013, the Company's cumulative liability for gross unrecognized tax benefits was $12,596. The Company had accrued $2,100 for cumulative penalties and $2,108 for cumulative interest at December 31, 2013. As of December 31, 2012, the Company's cumulative liability for gross unrecognized tax benefits was $12,410. The Company had accrued $1,630 for cumulative penalties and $2,288 for cumulative interest at December 31, 2012.
The Company continues to recognize interest and penalties associated with uncertain tax positions as a component of taxes on income before equity in net income of associated companies in its Consolidated Statement of Income. The Company recognized $392 for penalties and ($247) for interest (net of expirations and settlements) on its 2013 Consolidated Statement of Income, $301 for penalties and ($26) for interest (net of expirations and settlements) on its 2012 Consolidated Statement of Income and $502 for penalties and $529 for interest (net of expirations and settlements) on its 2011 Consolidated Statement of Income.
The Company estimates that during the year ending December 31, 2014, it will reduce its cumulative liability for gross unrecognized tax benefits by approximately $1,700 to $1,800 due to the expiration of the statute of limitations with regard to certain tax positions. This estimated reduction in the cumulative liability for unrecognized tax benefits does not consider any increase in liability for unrecognized tax benefits with regard to existing tax positions or any increase in cumulative liability for unrecognized tax benefits with regard to new tax positions for the year ending December 31, 2014.
The Company and its subsidiaries are subject to U.S. Federal income tax, as well as the income tax of various state and foreign tax jurisdictions. Tax years that remain subject to examination by major tax jurisdictions include Brazil from 2000, The Netherlands from 2007, United Kingdom from 2008, Spain from 2009, the United States, China and Italy from 2010 and various domestic state tax jurisdictions from 1993.
In the first quarter of 2013, the Internal Revenue Service (“IRS”) initiated a limited scope audit of the Company's 2010 Federal Income Tax Return. By letter dated March 25, 2013, the IRS notified the Company that it had completed the review of the Company's 2010 Federal Income Tax Return without any changes to the reported tax.
During the second quarter of 2012, the Italian tax authorities initiated a transfer pricing audit of the Company's Italian subsidiary. On July 7, 2012, the Company received a preliminary tax report related to this transfer pricing audit, which proposed several adjustments to the taxable income of the subsidiary. During the fourth quarter of 2012, the Company's Italian subsidiary received an assessment for the tax year 2007, which the Company appealed during the first quarter of 2013. On June 24, 2013, a hearing was held before the Provincial Tax Court of Varese, Italy. On September 16, 2013, the Provincial Tax Court of Varese delivered a decision confirming the Italian tax authorities' proposed adjustment to the taxable income of the subsidiary, but denying the proposed assessment of penalties. On January 24, 2014, Company's Italian subsidiary appealed the decision of the Provincial Tax Court of Varese.
On November 29, 2013, the Italian tax authorities issued a tax assessment for the tax year 2008, raising identical issues as the assessment for 2007, noted above. The Company intends to file an appeal with the Provincial Tax Court of Varese and apply for competent authority relief between the Italian and Dutch tax authorities.
Related to each of the above events, the Company and outside counsel believe we should prevail on the merits of each case.  Therefore, the Company does not believe it has any exposures warranting an uncertain tax position reserve as of December 2013.
A reconciliation of the beginning and ending amounts of unrecognized tax benefits for the years ended December 31, 2013, December 31, 2012 and December 31, 2011, respectively, is as follows:
			2013			2012			2011
Unrecognized tax benefits at January 1		$	12,410		$	12,719		$	10,464
	Increase in unrecognized tax benefits taken in prior periods		83			0			1,597
	(Decrease) in unrecognized tax benefits taken in prior periods		0			-411			0
	Increase in unrecognized tax benefits taken in current period		2,182			1,733			2,623
	(Decrease) in unrecognized tax benefits due to lapse of statute of limitations		-2,485			-1,837			-1,578
	Increase (decrease) due to foreign exchange rates		406			206			-387
Unrecognized tax benefits at December 31		$	12,596		$	12,410		$	12,719
The amount of unrecognized tax benefits above that, if recognized, would impact the Company's tax expense and effective tax rate is $1,194, $1,652 and $2,966 in 2013, 2012 and 2011, respectively.

	During 2013, certain internal shifts in the Company's management and changes to the structure of internally reported information occurred. The Company currently believes its structure, its resource allocation and its performance assessment are now more closely aligned with its four geographical regions: North America, EMEA, Asia/Pacific and South America. See Note 3 of Notes to Consolidated Financial Statements for further information. Similarly, the Company reassessed and changed its reporting units for goodwill testing purposes during 2013 to adhere to its geographical orientation. Based on its revised reporting units, the Company completed its annual impairment test as of the end of the third quarter of 2013 and no impairment charge was warranted. The estimated fair value of each of the Company's reporting units substantially exceeded its carrying value, with none of the Company's reporting units at risk for failing step one of the goodwill impairment test. In addition, the Company has recorded no impairment charges in the past.
	Changes in the carrying amount of goodwill for the years ended December 31, 2013 and December 31, 2012 were as follows:

	As of December 31, 2013, the Company held a 50% investment in and had significant influence over Kelko Quaker Chemical, S.A. (Venezuela), Nippon Quaker Chemical, Ltd. (Japan) and Kelko Quaker Chemical S.A. (Panama) and held a 33% investment in and had significant influence over Primex, Ltd. (Barbados).
	During the first quarter of 2013, the Company identified errors in Primex's estimated 2012 financial statements, which primarily related to a reinsurance contract held by Primex. The identified errors resulted in a cumulative $1,038 understatement of the Company's equity in net income from associated companies for the year ended December 31, 2012, which were corrected in the first quarter of 2013. See Note 2 of Notes to Consolidated Financial Statements for further information.
	Venezuela's economy is considered to be hyper inflationary under generally accepted accounting principles in the United States. Accordingly, all gains and losses resulting from the remeasurement of the Company's Venezuelan equity affiliate (Kelko Quaker Chemical, S.A.) are required to be recorded directly to the Consolidated Statement of Income. In February 2013, the Venezuelan Government announced a devaluation of the Bolivar Fuerte. Accordingly, the Company recorded a charge of approximately $357, or $0.03 per diluted share, in equity in net income of associated companies during the first quarter of 2013.
	In 2011, the Company purchased the remaining 60% ownership interest in Tecniquimia Mexicana, S.A. de C.V., the Company's Mexican equity affiliate. As a result of the purchase, the Company only included six months of the affiliate's 2011 results in its investments in associated companies, with the remaining six months after acquisition being reflected as a wholly owned subsidiary in the Company's Consolidated Financial Statements.
	The carrying amount of the Company's equity investments at December 31, 2013 was $19,397, which included investments of $12,094 in Primex, Ltd. (Barbados), assigned to the Company's North American segment; $5,267, in Nippon Quaker Chemical, Ltd. (Japan), assigned to the Company's Asia/Pacific segment; $1,652 in Kelko Quaker Chemical, S.A. (Venezuela), assigned to the Company's South American segment; and $384, in Kelko Quaker Chemical, S.A. (Panama), assigned to the Company's South American segment.
	Summarized financial information of Kelko Quaker Chemical, S.A. (Venezuela), Nippon Quaker Chemical, Ltd. (Japan) and Kelko Quaker Chemical S.A. (Panama), in the aggregate, is as follows:

	As noted above, the Company identified errors in Primex's estimated 2012 financial statements during the first quarter of 2013, which were corrected in the first quarter of 2013. The identified errors resulted in increases to Primex's revenue of $4,905, income before taxes of $5,240 and net income of $3,422, which are included in the 2013 summarized financial information for Primex above.
	During the first quarter of 2013, the Company received its first dividend distribution from Primex, Ltd. of approximately $2,000, which was accounted for as a reduction of the Company's investment balance in this associated company.

	Previously, an inactive subsidiary of the Company executed separate settlement and release agreements with two of its insurance carriers for $35,000, of which $25,462 remains. The proceeds of both settlements are restricted and can only be used to pay claims and costs of defense associated with the subsidiary's asbestos litigation. The proceeds of the settlement and release agreements have been deposited into interest bearing accounts which earned approximately $52 and $69 in 2013 and 2012, respectively, offset by $988 and $1,391 of payments in 2013 and 2012, respectively. Due to the restricted nature of the proceeds, a corresponding deferred credit was established in “Other non-current liabilities” for an equal and offsetting amount, and will remain until the restrictions lapse or the funds are exhausted via payments of claims and costs of defense.

	As discussed in the Current Report on Form 8-K filed on June 17, 2013, the Company entered into a revised syndicated multicurrency credit facility on June 14, 2013, which amended and replaced the Company's previous credit facility with Bank of America, N.A. and certain other major financial institutions. The revised facility increased the maximum principal amount available for revolving credit borrowings under this facility from $175,000 to $300,000, which can be increased to $400,000 at the Company's option if the lenders agree and the Company satisfies certain conditions. This facility matures in June 2018. In addition, the revised facility amended certain financial, acquisition and other covenants, but the consolidated leverage ratio calculation, for which access to credit under the former facility largely depended upon, remains relatively consistent and cannot exceed 3.50 to 1. As of December 31, 2013 and December 31, 2012, the Company's consolidated leverage ratio was below 1.0 to 1 and the Company was also in compliance with all of the current and former facilities' other covenants, respectively. At December 31, 2013 and December 31, 2012, the Company had approximately $0 and $12,200 outstanding on these credit lines at weighted average borrowing rates of 1.66% and 2.03% (LIBOR plus a spread) during each respective year.
	As part of its Middletown, Ohio facility's past expansion project, the Company agreed to a low interest rate $3,500 loan with the Ohio Department of Development. Principal repayment on this loan began in September 2010 with its final maturity being in 2021. The current interest rate of 1% will rise to 2% beginning January 1, 2014 and to 3% beginning January 1, 2019 until final maturity.
	At December 31, 2013 and December 31, 2012, the amounts at which the Company's debt is recorded are not materially different from their fair market value.

As of December 31, 2013 and December 31, 2012, “Other” consisted principally of cash and cash equivalents (approximately 2% of plan assets in each respective period).
The following is a description of the valuation methodologies used for the investments measured at fair value, including the general classification of such instruments pursuant to the valuation hierarchy:
Cash and Cash Equivalents
Cash and cash equivalents consist of cash and money market funds and are classified as Level 1 investments.
Registered Investment Companies
The shares of registered investment companies, which represent the net asset values of shares held by the Plan, are valued at quoted market prices in an exchange and active market and are classified as Level 1 investments.
Common Stock
Common stock is valued at quoted market prices in an exchange and active market and is classified as Level 1 investments.
Corporate Fixed Income Securities
Corporate fixed income securities are valued at quoted market prices in an exchange and active market and are classified as Level 1 investments.
U.S. and Foreign Government Fixed Income Securities
U.S. and foreign government securities are valued at quoted market prices in an exchange and active market and are classified as Level 1 investments.
Pooled Separate Accounts
Pooled separate accounts consist of insurance annuity contracts and are valued based on the reported unit value at year end. Units of the pooled separate accounts are not traded in an active exchange or market; however, valuation is based on the underlying investments of the units and are classified as Level 2 investments.
Diversified Equity Securities of Registered Investment Companies
Investments in diversified equity securities of registered investment companies are based upon the quoted redemption value of shares in the fund owned by the plan at year end. The shares of the fund are not available in an exchange or active market; however, the fair value is determined based on the underlying investments in the fund as traded in an exchange and active market and are classified as Level 2 investments.
Fixed Income Securities of Registered Investment Companies
Investments in fixed income securities of registered investment companies are based upon the quoted redemption value of shares in the fund owned by the plan at year end. The shares of the fund are not available in an exchange or active market; however, the fair value is determined based on the underlying investments in the fund as traded in an exchange and active market and are classified as Level 2 investments.
Insurance Contract
Investments in the foreign pension plan insurance contract are valued at reported cash surrender value of the contract at year end. Cash surrender value is determined based on unobservable inputs, which are contractually determined, regarding returns, fees, and the present value of the future cash flows of the contract. The contract is classified as a Level 3 investment.
Real Estate
The foreign pension plan's investment in real estate consists of an investment in a property fund. The fund's underlying investments consist of real property, which are valued using unobservable inputs. The property fund is classified as a Level 3 investment.
As of December 31, 2013 and December 31, 2012, the U.S. and foreign plans' investments measured at fair value on a recurring basis were as follows:

During 2013, it was discovered that the Company's subsidiary in the United Kingdom did not appropriately amend a trust for a legacy change in its pension scheme, as it related to a past retirement age equalization law. Given the lack of an official deed to the pension trust, the effective date of the change to the subsidiary's pension scheme will differ from the Company's historical beliefs. The Company is currently assessing the impact of such adjustment but, at December 31, 2013, cannot accurately estimate a potential exposure.
Cash Flows
Contributions
The Company expects to make minimum cash contributions of $6,172 to its pension plans ($1,989 Domestic and $4,183 Foreign) and $607 to its other postretirement benefit plan in 2014.
Estimated Future Benefit Payments
The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid:
													Other
			Pension Benefits										Postretirement
				Foreign			Domestic			Total			Benefits
		2014	$	1,968		$	4,872		$	6,840		$	607

		2019 and beyond		17,822			22,096			39,918			2,043
The Company maintains a plan under which supplemental retirement benefits are provided to certain officers. Benefits payable under the plan are based on a combination of years of service and existing postretirement benefits. Included in total pension costs are charges of $811, $700 and $628 in 2013, 2012 and 2011, respectively, representing the annual accrued benefits under this plan.
Defined Contribution Plan
The Company has a 401(k) plan with an employer match covering substantially all domestic employees. The plan allows for and the Company has paid a nonelective contribution on behalf of participants who have completed one year of service equal to 3% of the eligible participants' compensation in the form of Company common stock. Total Company contributions were $2,027, $1,703 and $1,624 for 2013, 2012 and 2011, respectively.

	In May 2013, the Company acquired a business that primarily related to tin plating for its North American reportable operating segment for net consideration of approximately $1,831. The Company allocated the purchase price to $830 of intangible assets, comprised of formulations, to be amortized over 10 years; a non-competition agreement, to be amortized over 4 years; and a customer list, to be amortized over 10 years. In addition, the Company recorded $277 of goodwill, all of which will be tax deductible. The remaining purchase price was allocated between the acquisition date fair value of inventory purchased of $454 and fixed assets purchased of $270.
	In January 2013, the Company acquired a chemical milling maskants distribution network for net consideration of approximately $647, which was assigned to the North American reportable operating segment. The Company also assumed an additional $100 hold-back of consideration for potential indemnity obligations, which was paid to the former shareholders during January 2014. The acquired intangible was allocated to the Company's customer lists and rights to sell intangible assets and will be amortized over 5 years.
	In July 2012, the Company acquired NP Coil Dexter Industries, S.r.l. for approximately $2,748, and assumed short-term and long-term debt of approximately $1,186 and $854, respectively. NP Coil Dexter is a manufacturer and supplier of metal surface treatment products. The Company allocated the purchase price to $3,825 of intangible assets, comprised of trademarks and formulations, to be amortized over 10 years; two customer lists to be amortized over 8 and 4 years, respectively; and a non-competition agreement to be amortized over 5 years. In addition, the Company recorded $1,786 of goodwill, none of which will be tax deductible and was assigned to the EMEA reportable operating segment. Liabilities assumed included a hold-back of consideration to be paid to the former shareholders at 18 months from the acquisition date. During the fourth quarter of 2012, the Company recorded an increase to other income of approximately $1,033 on its Consolidated Statement of Income related to a change in the fair value of this hold-back of consideration liability.
	In October 2011, the Company acquired G.W. Smith & Sons, Inc. for approximately $14,518. G.W. Smith manufactures and distributes high quality die casting lubricants, and also distributes metalworking fluids. The Company allocated the purchase price to $6,260 of intangible assets, comprised of trade names and formulations, to be amortized over 15 years; a trademark to be amortized over 5 years; a non-competition agreement to be amortized over 5 years; and customer lists to be amortized over 16 years.

	In July 2011, the Company acquired the remaining 60% ownership interest in Tecniquimia Mexicana, S.A. de C.V., the Company's Mexican equity affiliate, for approximately $10,500. As part of the acquisition, the Company recorded a one-time increase to other income of approximately $2,718 to revalue the previously held ownership interest in Tecniquimia to its fair value. The acquisition of Tecniquimia allowed the Company to further capitalize on the growing Mexican market. The Company allocated the purchase price to $3,556 of intangible assets, comprised of trade names and trademarks, to be amortized over 5 years; and customer lists, to be amortized over 20 years. In addition, the Company recorded $6,773 of goodwill, none of which will be tax deductible, and was assigned to the North American reportable operating segment.

	The fair values of Company-owned life insurance (“COLI”) and COLI deferred compensation assets are based on quotes for like instruments with similar credit ratings and terms. The fair values of other deferred compensation assets and liabilities are based on quoted prices in active markets. The fair value of the Summit earnout has been based on unobservable inputs and is classified as Level 3. Significant inputs and assumptions were management's estimate of the probability of the earnout ultimately being met/paid and the discount rate used to present value the liability. The fair value of the obligation related to a non-competition agreement is also based on unobservable inputs and is classified as Level 3. The significant inputs and assumptions for the obligation related to the non-competition agreement is management's estimate of the discount rate used to present value the liability. A significant change in any Level 3 assumption in isolation would result in increases or decreases to the fair value measurements of the acquisition-related consideration.
	Changes in the fair value of the Level 3 liabilities during the year ended December 31, 2013 were as follows:
							Non-competition
				Earnout			Agreement
				Summit			Obligation			Total
	Balance at December 31, 2012		$	4,497		$	404		$	4,901

	Balance at December 31, 2013		$	4,697		$	179		$	4,876
During the first quarter of 2013, the Summit earnout liability became current and was reclassified from other non-current liabilities to other current liabilities on the Company's Consolidated Balance Sheet, as the Company expects to settle the obligation within the next year.
Quantitative information about the Company's Level 3 fair value measurements at December 31, 2013 were as follows:
		Fair value at December 31, 2013		Valuation technique		Unobservable input		Input value
Summit earnout		4,697		Discounted cash flow		Discount rate		14.50%
Non-competition agreement obligation		179		Discounted cash flow		Discount rate		14.00%
At December 31, 2013, the Summit earnout liability was formulated based on the former acquisition's actual performance and is management's estimate of the likely payout under the earnout criteria. Prior to December 31, 2013, the determination of the fair value of the Summit earnout was based on the weighted average probability of the outcome of different payout scenarios. The probabilities applied to the payout scenarios prior to the fourth quarter of 2013 ranged from 15% to 70%, depending on the Company's estimate of the likelihood of each payout scenario.

Commitments and Contingencies Disclosure [Abstract]	'
Commitments And Contingencies Disclosure [Text Block]	'
	Note 22 – Commitments and Contingencies
	In April of 1992, the Company identified certain soil and groundwater contamination at AC Products, Inc. (“ACP”), a wholly owned subsidiary. In voluntary coordination with the Santa Ana California Regional Water Quality Board (“SACRWQB”), ACP has been remediating the contamination, the principal contaminant of which is perchloroethylene (“PERC”). On or about December 18, 2004, the Orange County Water District (“OCWD”) filed a civil complaint in Superior Court in Orange County, California against ACP and other parties potentially responsible for groundwater contamination. OCWD was seeking to recover compensatory and other damages related to the investigation and remediation of the contamination in the groundwater. Effective October 17, 2007, ACP and OCWD settled all claims related to this litigation. Pursuant to the settlement agreement with OCWD, ACP agreed to pay $2,000. In addition to the $2,000 payment, ACP agreed to operate the two existing groundwater treatment systems associated with its extraction wells P-2 and P-3 so as to hydraulically contain groundwater contamination emanating from ACP's site until such time as the concentrations of PERC are below the current Federal maximum contaminant level for four consecutive quarterly sampling events. On September 11, 2012, ACP received a letter from the SACRWQB advising that no further action is required to remediate the soil contamination on site. As of December 31, 2013, the Company believes that the range of potential-known liabilities associated with the ACP water remediation program is approximately $395 to $800, for which the Company has sufficient reserves.
	The low and high ends of the range are based on the length of operation of an offsite extraction well as determined by groundwater modeling with planned higher maintenance costs in later years if a longer treatment period is required. Costs of operation include the operation and maintenance of the extraction well, groundwater monitoring and program management. The duration of the well operation was estimated based on historical trends in concentrations in the monitoring well within the proximity of the applicable extraction well. Also factored into the model was the impact of water injected into the underground aquifer from a planned water treatment system to be installed by OCWD adjacent to P-2. Based on the modeling, it is estimated that P-2 will operate for another nine months to two years. The Company is in the process of closing P-3. Operation and maintenance costs were based on historical expenditures and estimated inflation. As mentioned above, a significantly higher maintenance expense was factored into the range if the system operates for the longer period.
	The Company believes, although there can be no assurance regarding the outcome of other unrelated environmental matters, that it has made adequate accruals for costs associated with other environmental problems of which it is aware. Approximately $205 and $230 was accrued at December 31, 2013 and December 31, 2012, respectively, to provide for such anticipated future environmental assessments and remediation costs.
	An inactive subsidiary of the Company that was acquired in 1978 sold certain products containing asbestos, primarily on an installed basis, and is among the defendants in numerous lawsuits alleging injury due to exposure to asbestos. The subsidiary discontinued operations in 1991 and has no remaining assets other than the proceeds from insurance settlements received. To date, the overwhelming majority of these claims have been disposed of without payment and there have been no adverse judgments against the subsidiary. Based on a continued analysis of the existing and anticipated future claims against this subsidiary, it is currently projected that the subsidiary's total liability over the next 50 years for these claims is approximately $2,700 (excluding costs of defense). Although the Company has also been named as a defendant in certain of these cases, no claims have been actively pursued against the Company, and the Company has not contributed to the defense or settlement of any of these cases pursued against the subsidiary. These cases were handled by the subsidiary's primary and excess insurers who had agreed in 1997 to pay all defense costs and be responsible for all damages assessed against the subsidiary arising out of existing and future asbestos claims up to the aggregate limits of the policies. A significant portion of this primary insurance coverage was provided by an insurer that is now insolvent, and the other primary insurers have asserted that the aggregate limits of their policies have been exhausted. The subsidiary challenged the applicability of these limits to the claims being brought against the subsidiary. In response, two of the three carriers entered into separate settlement and release agreements with the subsidiary in late 2005 and early 2007 for $15,000 and $20,000, respectively. The proceeds of both settlements are restricted and can only be used to pay claims and costs of defense associated with the subsidiary's asbestos litigation. During the third quarter of 2007, the subsidiary and the remaining primary insurance carrier entered into a Claim Handling and Funding Agreement, under which the carrier will pay 27% of defense and indemnity costs incurred by or on behalf of the subsidiary in connection with asbestos bodily injury claims for a minimum of five years beginning July 1, 2007. The agreement continues until terminated and can only be terminated by either party by providing the other party with a minimum of two years prior written notice. As of December 31, 2013, no notice of termination has been given under this agreement. At the end of the term of the agreement, the subsidiary may choose to again pursue its claim against this insurer regarding the application of the policy limits. The Company also believes that, if the coverage issues under the primary policies with the remaining carrier are resolved adversely to the subsidiary and all settlement proceeds were used, the subsidiary may have limited additional coverage from a state guarantee fund established following the insolvency of one of the subsidiary's primary insurers. Nevertheless, liabilities in respect of claims may exceed the assets and coverage available to the subsidiary.
	If the subsidiary's assets and insurance coverage were to be exhausted, claimants of the subsidiary may actively pursue claims against the Company because of the parent-subsidiary relationship. Although asbestos litigation is particularly difficult to predict, especially with respect to claims that are currently not being actively pursued against the Company, the Company does not believe that such claims would have merit or that the Company would be held to have liability for any unsatisfied obligations of the subsidiary as a result of such claims. After evaluating the nature of the claims filed against the subsidiary and the small number of such claims that have resulted in any payment, the potential availability of additional insurance coverage at the subsidiary level, the additional availability of the Company's own insurance and the Company's strong defenses to claims that it should be held responsible for the subsidiary's obligations because of the parent-subsidiary relationship, the Company believes it is not probable that the Company will incur any material losses. The Company has been successful to date having claims naming it dismissed during initial proceedings. Since the Company may be in this early stage of litigation for some time, it is not possible to estimate additional losses or range of loss, if any.
	As initially disclosed in the Company's second quarter 2010 Form 10-Q, one of the Company's subsidiaries may have paid certain value-added-taxes (“VAT”) incorrectly and, in certain cases, may not have collected sufficient VAT from certain customers. The VAT rules and regulations at issue are complex, vary among the jurisdictions and can be contradictory, in particular as to how they relate to the subsidiary's products and to sales between jurisdictions.
	Since its inception, the subsidiary had been consistent in its VAT collection and remittance practices and had never been contacted by any tax authority relative to VAT. The subsidiary later determined that for certain products, a portion of the VAT was incorrectly paid and that the total VAT due exceeds the amount originally collected and remitted by the subsidiary. In response, the subsidiary modified its VAT invoicing and payment procedures to eliminate or mitigate future exposure. In 2010, three jurisdictions contacted the subsidiary and, since then, the subsidiary has either participated in an amnesty program or entered into a settlement whereby it paid a reduced portion of the amounts owed in resolution of those jurisdictions' claims. In late 2013, an additional jurisdiction issued an assessment against the subsidiary for certain tax years. The subsidiary has filed an appeal of the assessment alleging certain errors by such jurisdiction related to the assessment.
	In analyzing the subsidiary's exposure, it is difficult to estimate both the probability and the amount of any potential liabilities due to a number of factors, including: the decrease in exposure over time due to applicable statutes of limitations and actions taken by the subsidiary, the joint liability of customers and suppliers for a portion of the VAT, the availability of a VAT refund for VAT incorrectly paid through an administrative process, any amounts which may have been or will be paid by customers, as well as the timing and structure of any tax amnesties or settlements. In addition, interest and penalties on any VAT due can be a multiple of the base tax. The subsidiary may contest any tax assessment administratively and/or judicially for an extended period of time, but may ultimately resolve its disputes through participation in tax amnesty programs, which are a common practice for settling tax disputes in the jurisdictions in question and which have historically occurred on a regular basis, resulting in significant reductions of interest and penalties. Also, the timing of payments and refunds of VAT may not be contemporaneous, and, if additional VAT is owed, it may not be fully recoverable from customers. As a result, this matter has the potential to have a material adverse impact on the Company's financial position, liquidity and capital resources and the results of operations.
	In 2010, the Company recorded a net charge of $4,132, which consisted of a net $3,901 charge related to two tax dispute settlements entered into by the subsidiary, as well as a net $231 charge representing management's best estimate based on the information available to it, including the factors noted above, of the amount that ultimately may be paid related to the other jurisdiction that has made inquiries. At December 31, 2013 and December 31, 2012, the Company had no remaining accrual, related to the 2010 charges, for payments to be made under the tax dispute settlements entered into by the subsidiary, noted above. In the fourth quarter of 2013, the Company recorded a net charge of $796, representing the Company's best estimate of the amount that ultimately may be paid related to the 2013 assessment referenced above.
	The charges taken by the Company in 2010 and in the fourth quarter of 2013 assume a successful recovery of the VAT incorrectly paid, as well as reductions in interest and penalties from anticipated future amnesty programs or settlements. On a similar basis, if all other potentially impacted jurisdictions were to initiate audits and issue assessments, the remaining exposure, net of refunds, could be from $0 to $7,200 with one jurisdiction representing approximately 78 percent of this additional exposure, assuming the continued availability of future amnesty programs or settlements to reduce the interest and penalties. If there are future assessments but no such future amnesty programs or settlements, the potential exposure could be higher.
	The Company is party to other litigation which management currently believes will not have a material adverse effect on the Company's results of operations, cash flows or financial condition.
	The Company leases certain manufacturing and office facilities and equipment under non-cancelable operating leases with various terms from 1 to 5 years expiring in 2018. Rent expense for 2013, 2012 and 2011 was $5,510, $5,189, and $5,282, respectively.
	The Company's minimum rental commitments under non-cancelable operating leases at December 31, 2013 for future years were approximately:
		2014	$	4,991
		2015	$	4,154
		2016	$	3,507
		2017	$	1,812
		2018	$	5
		2019 and beyond	$	0

Significant_Accounting_Policie1

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
Organization, Consolidation and Presentation of Financial Statements [Abstract]	'
Consolidation, Policy [Policy Text Block]	'
	All majority-owned subsidiaries are included in the Company's consolidated financial statements, with appropriate elimination of intercompany balances and transactions.
Consolidation, Variable Interest Entity, Policy [Policy Text Block]	'
	The Financial Accounting Standards Board's (“FASB's”) guidance regarding the consolidation of certain Variable Interest Entities (“VIEs”) generally requires that assets, liabilities and results of the activities of a VIE be consolidated into the financial statements of the enterprise that is considered the primary beneficiary. The consolidated financial statements include the accounts of the Company and all of its subsidiaries in which a controlling interest is maintained and would include any VIEs if the Company was the primary beneficiary pursuant to the provisions of the applicable guidance.
Equity and Cost Method Investments, Policy [Policy Text Block]	'
	Investments in associated companies (less than majority-owned and in which the Company has significant influence) are accounted for under the equity method. The Company's share of net income or losses in these investments in associated companies is included in the Consolidated Statement of Income. The Company periodically reviews these investments for impairments and, if necessary, would adjust these investments to their fair value when a decline in market value or other impairment indicators are deemed to be other than temporary.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	'
	Translation of foreign currency: Assets and liabilities of non-U.S. subsidiaries and associated companies are translated into U.S. Dollars at the respective rates of exchange prevailing at the end of the year. Income and expense accounts are translated at average exchange rates prevailing during the year. Translation adjustments resulting from this process are recorded directly in equity as accumulated other comprehensive income (loss) and will be included as income or expense only upon sale or liquidation of the underlying investment. All non-U.S. subsidiaries use their local currency as their functional currency.
Cash and Cash Equivalents, Policy [Policy Text Block]	'
	Cash and cash equivalents: The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents.
Inventory, Policy [Policy Text Block]	'
	Inventories: Inventories are valued at the lower of cost or market value, and are valued using the first-in, first-out (“FIFO”) method.
Property, Plant and Equipment, Policy [Policy Text Block]	'
	Long-lived assets: Property, plant and equipment are stated at cost. Depreciation is computed using the straight-line method on an individual asset basis over the following estimated useful lives: buildings and improvements, 10 to 45 years; and machinery and equipment, 1 to 15 years. The carrying value of long-lived assets is periodically evaluated whenever changes in circumstances or current events indicate the carrying amount of such assets may not be recoverable. An estimate of undiscounted cash flows produced by the asset, or the appropriate group of assets, is compared with the carrying value to determine whether an impairment exists. If necessary, the Company recognizes an impairment loss for the difference between the carrying amount of the assets and their estimated fair value. Fair value is based on current and anticipated future undiscounted cash flows. Upon sale or other dispositions of long-lived assets, the applicable amounts of asset cost and accumulated depreciation are removed from the accounts and the net amount, less proceeds from disposals, is recorded in income. Expenditures for renewals or improvements that increase the estimated useful life or capacity of the assets are capitalized, whereas expenditures for repairs and maintenance are expensed when incurred.
Internal Use Software, Policy [Policy Text Block]	'
	Capitalized software: The Company capitalizes certain costs incurred in connection with developing or obtaining software for internal use. These costs are amortized over a period of three to five years once the assets are ready for their intended use.
Goodwill and Intangible Assets, Policy [Policy Text Block]	'
	Goodwill and other intangible assets: The Company records goodwill, definite-lived intangible assets and indefinite-lived intangible assets at fair value at the date of acquisition. Goodwill and indefinite-lived intangible assets are not amortized, but tested for impairment at least annually. These tests will be performed more frequently if triggering events indicate potential impairment. Definite-lived intangible assets are amortized over their estimated useful lives, generally for periods ranging from 5 to 20 years. The Company continually evaluates the reasonableness of the useful lives of these assets, consistent with the discussion of long-lived assets, above.
Revenue Recognition Accounting Policy, Gross and Net Revenue Disclosure [Policy Text Block]	'
	Revenue recognition: The Company recognizes revenue in accordance with the terms of the underlying agreements, when title and risk of loss have been transferred, when collectability is reasonably assured, and when pricing is fixed or determinable. This generally occurs when products are shipped to customers or, for consignment-type arrangements, upon usage by the customer and when services are performed. License fees and royalties are included in other income when recognized in accordance with their agreed-upon terms, when performance obligations are satisfied, when the amount is fixed or determinable, and when collectability is reasonably assured. As part of the Company's chemical management services, certain third-party product sales to customers are managed by the Company. Where the Company acts as a principal, revenues are recognized on a gross reporting basis at the selling price negotiated with its customers. Where the Company acts as an agent, such revenue is recorded using net reporting as service revenue at the amount of the administrative fee earned by the Company for ordering the goods.
Receivables, Trade and Other Accounts Receivable, Allowance for Doubtful Accounts, Policy [Policy Text Block]	'
	Accounts receivable and allowance for doubtful accounts: Trade accounts receivable are recorded at the invoiced amount and generally do not bear interest. The allowance for doubtful accounts is the Company's best estimate of the amount of probable credit losses with its existing accounts receivable. Reserves for customers filing for bankruptcy protection are generally established at 75-100% of the amount owed at the filing date, dependent on the Company's evaluation of likely proceeds from the bankruptcy process. Large and/or financially distressed customers are generally reserved for on a specific review basis while a general reserve is established for other customers based on historical experience. The Company performs a formal review of its allowance for doubtful accounts quarterly. Account balances are charged off against the allowance when the Company feels it is probable the receivable will not be recovered. The Company does not have any off-balance-sheet credit exposure related to its customers.
Research and Development Expense, Policy [Policy Text Block]	'
	Research and development costs: Research and development costs are expensed as incurred and are included in SG&A.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	'
	Concentration of credit risk: Financial instruments, which potentially subject the Company to a concentration of credit risk, principally consist of cash equivalents, short-term investments and trade receivables. The Company invests temporary and excess funds in money market securities and financial instruments having maturities typically within 90 days. The Company has not experienced losses from the aforementioned investments.
Environmental Costs, Policy [Policy Text Block]	'
	Environmental liabilities and expenditures: Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. If there is a range of estimated liability and no amount in that range is considered more probable than another, then the Company records the lowest amount in the range in accordance with generally accepted accounting principles. Accrued liabilities are exclusive of claims against third parties and are not discounted. Environmental costs and remediation costs are capitalized if the costs extend the life, increase the capacity or improve safety or efficiency of the property from the date acquired or constructed, and/or mitigate or prevent contamination in the future.
Asset Retirement Obligations, Policy [Policy Text Block]	'
	Asset retirement obligations: The Company follows the FASB's guidance regarding asset retirement obligations, which addresses the accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated retirement costs. Also, the Company follows the FASB's guidance for conditional asset retirement obligations (“CARO”), which relates to legal obligations to perform an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event that may or may not be within the control of the entity. In accordance with this guidance, the Company records a liability when there is enough information regarding the timing of the CARO to perform a probability-weighted discounted cash flow analysis.
Pension and Other Postretirement Plans, Policy [Policy Text Block]	'
	Pension and other postretirement benefits: The Company maintains various noncontributory retirement plans, the largest of which is in the U.S., covering substantially all of its employees in the U.S. and certain other countries. The plans of the Company's subsidiaries in The Netherlands, the United Kingdom and Mexico are subject to the provisions of FASB's guidance regarding employers' accounting for defined benefit pension plans. The plans of the remaining non-U.S. subsidiaries are, for the most part, either fully insured or integrated with the local governments' plans and are not subject to the provisions of the guidance. The guidance requires that employers recognize on a prospective basis the funded status of their defined benefit pension and other postretirement plans on their consolidated balance sheet and, also, recognize as a component of other comprehensive income, net of tax, the gains or losses and prior service costs or credits that arise during the period but are not recognized as components of net periodic benefit cost.
	The Company's U.S. pension plan year ends on November 30 and the measurement date is December 31. The measurement date for the Company's other postretirement benefits plan is December 31.
	The Company's pension investment policy is designed to ensure that pension assets are invested in a manner consistent with meeting the future benefit obligations of the pension plans and maintaining compliance with various laws and regulations including the Employee Retirement Income Security Act of 1974 (“ERISA”). The Company establishes strategic asset allocation percentage targets and appropriate benchmarks for significant asset classes with the aim of achieving a prudent balance between return and risk. The Company's investment horizon is generally long term, and, accordingly, the target asset allocations encompass a long-term perspective of capital markets, expected risk and return and perceived future economic conditions while also considering the profile of plan liabilities. To the extent feasible, the short-term investment portfolio is managed to immunize the short-term obligations, the intermediate portfolio duration is immunized to reduce the risk of volatility in intermediate plan distributions, and the total return portfolio is expected to maximize the long-term real growth of plan assets. The critical investment principles of diversification, assessment of risk and targeting the optimal expected returns for given levels of risk are applied. The Company's investment guidelines prohibit use of securities such as letter stock and other unregistered securities, commodities or commodity contracts, short sales, margin transactions, private placements (unless specifically addressed by addendum), or any derivatives, options or futures for the purpose of portfolio leveraging.
	The target asset allocation is reviewed periodically and is determined based on a long-term projection of capital market outcomes, inflation rates, fixed income yields, returns, volatilities and correlation relationships. The interaction between plan assets and benefit obligations is periodically studied to assist in establishing such strategic asset allocation targets. Asset performance is monitored with an overall expectation that plan assets will meet or exceed benchmark performance over rolling five-year periods. The Company's pension committee, as authorized by the Company's Board of Directors, has discretion to manage the assets within established asset allocation ranges approved by senior management of the Company.
Comprehensive Income, Policy [Policy Text Block]	'
	Comprehensive income (loss): The Company presents other comprehensive income (loss) in its Statement of Comprehensive Income. During 2013, the Company adopted the FASB's guidance regarding the disclosure of reclassifications from Accumulated Other Comprehensive Income (Loss) (“AOCI”). The guidance requires the disclosure of significant amounts reclassified from each component of AOCI, the related tax amounts and the income statement line items affected by the reclassifications, either parenthetically on the Consolidated Statement of Comprehensive Income or in the Notes to the Consolidated Financial Statements. The Company elected to present the information in the Notes to the Consolidated Financial Statements, and the adoption of this guidance did not have a material impact on the Company's results or financial condition.
Income Tax, Policy [Policy Text Block]	'
	Income taxes and uncertain tax positions: The provision for income taxes is determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes represents income taxes paid or payable for the current year and the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax bases of the Company's assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized.
Income Tax Uncertainties, Policy [Policy Text Block]	'
	The FASB's guidance regarding accounting for uncertainty in income taxes prescribes the recognition threshold and measurement attributes for financial statement recognition and measurement of tax positions taken or expected to be taken on a tax return. The guidance further requires the determination of whether the benefits of tax positions will be more likely than not sustained upon audit based upon the technical merits of the tax position. For tax positions that are determined to be more likely than not sustained upon audit, a company recognizes the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement in the financial statements. For tax positions that are not determined to be more likely than not sustained upon audit, a company does not recognize any portion of the benefit in the financial statements. Additionally, the guidance provides for derecognition, classification, penalties and interest, accounting in interim periods, disclosure and transition. The guidance also requires that the amount of interest expense and income to be recognized related to uncertain tax positions be computed by applying the applicable statutory rate of interest to the difference between the tax position recognized, including timing differences, and the amount previously taken or expected to be taken in a tax return. The Company's continuing practice is to recognize interest and/or penalties related to income tax matters in income tax expense.
	During 2013, the Company adopted guidance that requires an entity to net its liability for unrecognized tax benefits against deferred tax assets related to net operating losses or other tax credit carryforwards that would apply if the uncertain tax position were settled for the presumed amount at the balance sheet date, which had an immaterial impact on the Company's current year results and financial condition.
Derivatives, Policy [Policy Text Block]	'
	Derivatives: The Company is exposed to the impact of changes in interest rates, foreign currency fluctuations, changes in commodity prices and credit risk. The Company is currently not using derivative instruments to mitigate the risks associated with foreign currency fluctuations, changes in commodity prices or credit risk, but has used derivative financial instruments primarily for purposes of hedging exposures to fluctuations in interest rates in the past. The Company recognized all derivatives on its balance sheet at fair value. For derivative instruments designated as cash flow hedges, the effective portion of any hedge would be reported in Accumulated Other Comprehensive Income (Loss) until it was cleared to earnings during the same period in which the hedged item affected earnings. The Company currently uses no derivative instruments designated as fair value hedges and has not entered into derivative contracts for trading or speculative purposes.
Fair Value of Financial Instruments, Policy [Policy Text Block]	'
	Fair value measurements: The Company utilizes the FASB's guidance regarding fair value measurements, which establishes a common definition for fair value to be applied to guidance requiring use of fair value, establishes a framework for measuring fair value and expands disclosure about such fair value measurements. Specifically, the guidance utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels:
		•	Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities.
		•	Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.
		•	Level 3: Unobservable inputs that reflect the reporting entity's own assumptions.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	'
	Stock-based compensation: The Company applies the FASB's guidance regarding share-based payments, which requires the recognition of the fair value of stock-based compensation as a component of expense. The Company has a long-term incentive program (“LTIP”) for key employees which provides for the granting of options to purchase stock at prices not less than its market value on the date of the grant. Most options become exercisable between one and three years after the date of the grant for a period of time determined by the Company, but not to exceed seven years from the date of grant. Common stock awards and Restricted Stock Units (“RSU”) issued under the LTIP program are subject only to time vesting over a three to five-year period. In addition, as part of the Company's Global Annual Incentive Plan (“GAIP”), nonvested shares may be issued to key employees, which generally vest over a two to five-year period. Based on historical experience, the Company has generally assumed a forfeiture rate of 13% on its nonvested stock awards. The Company will record additional expense if the actual forfeiture rate is lower than estimated, and will record a recovery of prior expense if the actual forfeiture is higher than estimated.
Earnings Per Share, Policy [Policy Text Block]	'
	Earnings per share: The Company follows FASB's guidance regarding the calculation of earnings per share (“EPS”) for nonvested stock awards with rights to non-forfeitable dividends. The guidance requires nonvested stock awards with rights to non-forfeitable dividends to be included as part of the basic weighted average share calculation under the two-class method.
Segment Reporting, Policy [Policy Text Block]	'
	Segments: The Company's reportable operating segments evidence the structure of the Company's internal organization, the method by which the Company's resources are allocated and the manner by which the Company assesses its performance. During 2013, certain internal shifts in the Company's management and changes to the structure of internally reported information occurred. The Company currently believes its structure, its resource allocation and its performance assessment are now more closely aligned with its four geographical regions: the North America region, the Europe, Middle East and Africa (“EMEA”) region, the Asia/Pacific region and the South America region. Therefore, the Company changed its reportable operating segments from those categorized by product nature to those organized by geography. All prior period information has been recast to reflect these four regions as the Company's new reportable operating segments.
Reclassification, Policy [Policy Text Block]	'
	Reclassifications: Certain information has been reclassified to conform to the current year presentation.
Use of Estimates, Policy [Policy Text Block]	'
	Accounting estimates: The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and disclosure of contingencies at the date of the financial statements and the reported amounts of net sales and expenses during the reporting period. Actual results could differ from such estimates.

Accounting Changes And Error Corrections [Abstract]	'
Immaterial Error Correction	'During the first quarter of 2013, the Company identified errors in Primex’s estimated 2012 financial statements, which primarily related to a reinsurance contract held by Primex. The identified errors resulted in a cumulative $1,038 understatement of the Company’s equity in net income from associated companies for the year ended December 31, 2012. The Company corrected the errors related to Primex in the first quarter of 2013, which had the net effect of increasing equity in net income from associated companies by $1,038 for the three months ended March 31, 2013 and the year ended December 31, 2013. The Company does not believe this adjustment is material to its consolidated financial statements for the year ended December 31, 2012 or to the Company’s results for the year ended December 31, 2013 and, therefore, did not restate any prior period amounts.
Amount of Immaterial Misstatement	$1,038

Description Of Foreign Currency Devaluation Effects

'

'

'

'

'

'

'In February 2013, the Venezuelan Government announced a devaluation of the Bolivar Fuerte. Accordingly, the Company recorded a charge of approximately $357, or $0.03 per diluted share, in equity in net income of associated companies during the first quarter of 2013.

Immaterial Error Correction

'During the first quarter of 2013, the Company identified errors in Primex’s estimated 2012 financial statements, which primarily related to a reinsurance contract held by Primex. The identified errors resulted in a cumulative $1,038 understatement of the Company’s equity in net income from associated companies for the year ended December 31, 2012. The Company corrected the errors related to Primex in the first quarter of 2013, which had the net effect of increasing equity in net income from associated companies by $1,038 for the three months ended March 31, 2013 and the year ended December 31, 2013. The Company does not believe this adjustment is material to its consolidated financial statements for the year ended December 31, 2012 or to the Company’s results for the year ended December 31, 2013 and, therefore, did not restate any prior period amounts.

Loss Contingency, Settlement Agreement, Terms	'Previously, an inactive subsidiary of the Company executed separate settlement and release agreements with two of its insurance carriers for $35,000, of which $25,462 remains. The proceeds of both settlements are restricted and can only be used to pay claims and costs of defense associated with the subsidiary’s asbestos litigation.	'	'	'	'In response, two of the three carriers entered into separate settlement and release agreements with the subsidiary in late 2005 and early 2007 for $15,000 and $20,000, respectively. The proceeds of both settlements are restricted and can only be used to pay claims and costs of defense associated with the subsidiary’s asbestos litigation. During the third quarter of 2007, the subsidiary and the remaining primary insurance carrier entered into a Claim Handling and Funding Agreement, under which the carrier will pay 27% of defense and indemnity costs incurred by or on behalf of the subsidiary in connection with asbestos bodily injury claims for a minimum of five years beginning July 1, 2007. The agreement continues until terminated and can only be terminated by either party by providing the other party with a minimum of two years prior written notice. As of December 31, 2013, no notice of termination has been given under this agreement. At the end of the term of the agreement, the subsidiary may choose to again pursue its claim against this insurer regarding the application of the policy limits.	'	'	'	'	'
