Earnings Per Share [Abstract]
Antidilutive Securities Excluded from Computation of Earnings Per Share, Amount	1,905	718	0	3,480
Earnings Per Share Reconciliation Disclosure			The Company’s calculation of (loss) earnings per diluted share attributable to Quaker Chemical Corporation common shareholders for the three and nine months ended September 30, 2019 was impacted by the 4.3 million share issuance in connection with closing the Combination, comprising approximately 24.5% of the common stock of the Company as of September 30, 2019, as well as the variability of its reported earnings. Therefore, the per diluted share result for each of the first three quarters of 2019, as reported on a standalone basis, may not sum to the per diluted share result for the nine months ended September 30, 2019 .

Disclosure of the methodology and assumptions used in the reconciliation of earnings per share, which may include the individual income and share amount effects of all securities that affect earnings per share, the effect that has been given to preferred dividends in arriving at income available to common stockholders in computing basic earnings per share, securities (including those issuable pursuant to contingent stock agreements) that could potentially dilute basic EPS in the future that were not included in the computation of diluted EPS because to do so would have been antidilutive for the period(s) presented and a description of any transaction that occurs after the end of the most recent period but before issuance of the financial statements that would have changed materially the number of common shares or potential common shares outstanding at the end of the period if the transaction had occurred before the end of the period.
