Stockholders Equity Note Disclosure [Text Block] | Note 13 – Equity In May 2015, the Company’s Board of Directors authorized a share repurchase program for the repurchase of up to $100.0 million of Quaker Chemical Corporation common stock (the “2015 Share Repurchase Program”). The 2015 Share Repurchase Program has no expiration date. The 2015 Share Repurchase Program provides a framework of conditions under which management can repurchase shares of the Company’s common stock. These purchases may be made in the ope n market or in private and negotiated transactions and will be in accordance with applicable laws, rules and regulations. In connection with the 2015 Share Repurchase Program, the Company acquired 83,879 shares of common stock for $ 5.9 million during the six months ended June 30, 2016 . There were no share repurchases under the 2015 Share Repurchase Program during the six months ended June 30, 2017 . The Company has elected not to hold treasury shares, and, therefore, has retired the shares as they are repurchased. It is the Company’s accounting policy to record the excess paid over par value as a reduction in retained earnings for all shares repurchased.
