Segment Reporting [Abstract]
Segment Reporting	NOTE 2 – SEGMENT REPORTING The Company reports its financial performance based on the four reportable segments Fuel Specialties, Performance Chemicals, Oilfield Services and Octane Additives. The Fuel Specialties, Performance Chemicals and Oilfield Services segments operate in markets where we actively seek growth opportunities although their ultimate customers are different. The Octane Additives segment is expected to decline in the near future as our one remaining refinery customer transitions to unleaded fuel. The Company evaluates the performance of its segments based on operating income. The following tables analyze sales and other financial information by the Company’s reportable segments: Three Months Ended March 31 (in millions) 2017 2016 Net Sales: Refinery and Performance $ 100.4 $ 98.2 Other 26.0 25.2 Fuel Specialties 126.4 123.4 Personal Care 47.5 32.3 Home Care 26.9 0.3 Other 20.1 2.1 Performance Chemicals 94.5 34.7 Oilfield Services 66.5 36.2 Octane Additives 6.9 17.8 $ 294.3 $ 212.1 Three Months Ended March 31 (in millions) 2017 2016 Net sales: Fuel Specialties $ 126.4 $ 123.4 Performance Chemicals 94.5 34.7 Oilfield Services 66.5 36.2 Octane Additives 6.9 17.8 $ 294.3 $ 212.1 Gross profit: Fuel Specialties $ 46.1 $ 42.0 Performance Chemicals 16.7 10.8 Oilfield Services 25.4 11.6 Octane Additives 2.7 11.8 $ 90.9 $ 76.2 Operating income: Fuel Specialties $ 26.8 $ 23.9 Performance Chemicals 6.0 4.4 Oilfield Services 3.0 (5.5 ) Octane Additives 2.0 11.0 Pension credit 1.1 1.8 Corporate costs (10.7 ) (10.2 ) Adjustment to fair value of contingent consideration 0.0 1.6 Loss on disposal of subsidiary 0.0 (1.4 ) Foreign exchange loss on liquidation of subsidiary (1.8 ) 0.0 Total operating income $ 26.4 $ 25.6 The pension credit relates to the United Kingdom defined benefit pension plan which is closed to future service accrual.

Acquisition of Huntsman European Differentiated Surfactants Business On December 30, 2016 the Company acquired the European Differentiated Surfactants business (“Huntsman”) from Huntsman Investments (Netherlands) B.V.. We purchased the business for total consideration of $199.2 million subject to working capital adjustments. The measurement period for the valuation of assets acquired and liabilities assumed ends as soon as information on the facts and circumstances that existed as of the acquisition dates become available but does not exceed twelve months. During the three months ended March 31, 2017, we have reviewed the fair values of assets acquired and liabilities assumed in the acquisition of Huntsman, resulting in a $39.3 million increase in assets acquired and a corresponding decrease in goodwill. The following table summarizes the calculations of the total purchase price and the estimated allocation of the purchase price to assets and liabilities assumed for the business: (in millions) Huntsman Goodwill $ 68.1 Other intangible assets 33.5 Fixed assets 92.7 Other net assets acquired 4.9 Purchase price, net of cash acquired $ 199.2 The Company has provisionally allocated $33.5 million of the purchase price to other intangible assets which we are amortizing on a straight-line basis to the income statement over an estimated expected life of 10 years. These intangible assets principally relate to customer relationships and an amortization expense of $0.9 million was recognized in selling, general and administrative expenses for the three months ended March 31, 2017 (three months ended March 31, 2016 - $0.0 million). The Company has recorded measurement period adjustments to increase the fair value of the acquired tangible fixed assets of $16.2 million, a deferred tax liability of $10.3 million related to the fair valuations of intangible and tangible fixed assets and adjustments to other net assets totalling $0.1 million. The final purchase price, including net working capital adjustments, and fair value review of assets and liabilities acquired has not been finalized as at March 31, 2017. Huntsman, and the associated goodwill and other intangible assets, are included within our Performance Chemicals segment for management and reporting purposes. There is currently no goodwill amortizable for tax purposes.

The German plan is closed to new entrants and has no assets. The net pension charge for the German plan for the three months ended March 31, 2017 was $0.2 million (three months ended March 31, 2016 - $0.2 million). As at March 31, 2017, our Performance Chemicals segment has pension schemes in its European businesses with a liability of $4.2 million (December 31, 2016 - $4.1 million).

We recognize accrued interest and penalties associated with uncertain tax positions as part of income taxes in our consolidated statements of income. The Company or one of its subsidiaries files income tax returns with the U.S. federal government, and various state and foreign jurisdictions. As previously disclosed, one of the Company’s U.S. subsidiaries is currently subject to a state tax examination in respect of 2012 through to 2014 inclusive. The Company currently anticipates that adjustments, if any, arising out of this tax audit would not result in a material change to the Company’s financial position as at March 31, 2017. The Company and its U.S. subsidiaries remain open to examination by the IRS for years 2013 onwards. The Company’s subsidiaries in foreign tax jurisdictions are open to examination including France (2013 onwards), Germany (2015 onwards), Switzerland (2015 onwards) and the United Kingdom (2015 onwards). The Company is in a position to control whether or not to repatriate foreign earnings and we currently do not expect to make a repatriation in the foreseeable future. No taxes have been provided for on the unremitted earnings of our overseas subsidiaries as any tax basis differences relating to investments in these overseas subsidiaries are considered to be indefinite in duration. The amount of unremitted earnings at December 31, 2016 was approximately $788 million. If these earnings are remitted, additional taxes could result after offsetting foreign income taxes paid although the calculation of the additional taxes is not practicable to compute at this time.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Risk Management	NOTE 11 – DERIVATIVE INSTRUMENTS AND RISK MANAGEMENT The Company enters into various foreign currency forward exchange contracts to minimize currency exchange rate exposure from expected future cash flows. As at March 31, 2017 the contracts have maturity dates of up to eighteen months at the date of inception. These foreign currency forward exchange contracts have not been designated as hedging instruments, and their impact on the income statement for the first three months of 2017 was a loss of $0.5 million (first three months of 2016: gain of $1.5 million). The Company enters into interest rate swaps to minimize interest rate exposure related to a part of our borrowing requirements. These interest rate swaps have been designated as hedging instruments, and their impact on accumulated other comprehensive loss for the first three months of 2017 was a gain of $0.3 million (first three months of 2016: $0.0 million).

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 12 – COMMITMENTS AND CONTINGENCIES Legal matters While we are involved from time to time in claims and legal proceedings that result from, and are incidental to, the conduct of our business including business and commercial litigation, employee and product liability claims, there are no material pending legal proceedings to which the Company or any of its subsidiaries is a party, or of which any of their property is subject. It is possible, however, that an adverse resolution of an unexpectedly large number of such individual claims or proceedings could in the aggregate have a material adverse effect on the results of operations for a particular year or quarter. Guarantees The Company and certain of the Company’s consolidated subsidiaries are contingently liable for certain obligations of affiliated companies primarily in the form of guarantees of debt and performance under contracts entered into as a normal business practice. This includes guarantees of non-U.S. Under the terms of the guarantee arrangements, generally the Company would be required to perform should the affiliated company fail to fulfil its obligations under the arrangements. In some cases, the guarantee arrangements have recourse provisions that would enable the Company to recover any payments made under the terms of the guarantees from securities held of the guaranteed parties’ assets. The Company and its affiliates have numerous long-term sales and purchase commitments in their various business activities, which are expected to be fulfilled with no adverse consequences material to the Company.

Stock-Based Compensation Plans	NOTE 13 – STOCK-BASED COMPENSATION PLANS The Company grants stock options and stock equivalent units (“SEUs”) from time to time as a long-term performance incentive. In certain cases the grants are subject to performance conditions such as the Company’s stock price. Where performance conditions apply the Monte Carlo simulation model is used to determine the fair values. Otherwise the Black-Scholes model is used to determine the fair values. Stock option plans The following table summarizes the transactions of the Company’s stock option plans for the three months ended March 31, 2017: Number of Options Weighted Average Exercise Price Weighted Average Grant-Date Fair Value Outstanding at December 31, 2016 570,994 $ 20.38 $ 21.68 Granted - at discount 76,664 $ 0.00 $ 62.22 - at market value 18,843 $ 70.60 $ 16.84 Exercised (72,994 ) $ 12.92 $ 24.77 Forfeited (2,281 ) $ 9.62 $ 24.60 Outstanding at March 31, 2017 591,226 $ 20.30 $ 26.43 At March 31, 2017, there were 51,265 stock options that were exercisable, of which 11,695 had performance conditions attached. The stock option compensation cost for the first three months of 2017 was $1.0 million (2016 – $0.9 million). The total intrinsic value of options exercised in the first three months of 2017 was $1.8 million (2016 – $1.5 million). The total compensation cost related to non-vested Stock equivalent units The following table summarizes the transactions of the Company’s SEUs for the three months ended March 31, 2017: Number Weighted Average Exercise Price Weighted Average Grant-Date Fair Value Outstanding at December 31, 2016 279,815 $ 3.77 $ 33.40 Granted - at discount 174,249 $ 0.00 $ 62.83 - at market value 5,530 $ 70.60 $ 16.84 Exercised (29,989 ) $ 6.21 $ 26.38 Forfeited (11,775 ) $ 0.00 $ 32.69 Outstanding at March 31, 2017 417,830 $ 3.02 $ 45.97 At March 31, 2017 there were 59,624 SEUs that are exercisable, of which 54,256 had performance conditions attached. The charges for SEUs are spread over the life of the award subject to a revaluation to fair value each quarter. The revaluation may result in a charge or a credit to the income statement in the quarter dependent upon our share price and other performance criteria. The SEU compensation cost for the first three months of 2017 was $0.9 million (2016 – a credit of $1.0 million). The total intrinsic value of SEUs exercised in the first three months of 2017 was $0.9 million (2016 - $1.1 million). The weighted-average remaining vesting period of non-vested

Accounting Changes and Error Corrections [Abstract]
Recently Issued Accounting Pronouncements	NOTE 15 – RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS Effective January 2017, we prospectively adopted Accounting Standards Update (ASU) 2016-09, Improvements to Employee Share-based Payment Accounting which amends ASC Topic 718, Compensation Stock Compensation. The Standard requires recognition of the excess tax benefits or deficiencies of share-based compensation awards to employees through net income rather than additional paid in capital. The calculation of excess tax benefits or deficiencies is based on the difference between market value of an award at the vesting or at the time of exercise compared to the grant date fair value recognized as compensation expense in the consolidated statements of income. The Company expects the effective tax rate including stock compensation to vary quarter to quarter depending on the amount of pre-tax net income and on the timing of the stock option exercises. The Company has elected to restate prior period comparatives for cash flow purposes. Additionally, the guidance allows for an election to account for forfeitures related to share based payments either as they occur or an estimation method. We elected to calculate share-based compensation using actual forfeitures. This has not had a significant impact on our financial reporting. In February 2016, the FASB issued Accounting Standards Update (ASU) 2016-02, right-of-use In May 2014, the FASB issued Accounting Standards Update (ASU) 2014-09, 2014-09 2014-09 No. 2015-14, 2014-09 2014-09.
