在浮油或石油生产过程中形成的油包水乳液已知通过天然存在于原油中的表面活性剂分子来稳定，例如，在一个实施例中，沥青质，其在性质上是相当亲脂的。破乳剂物质联合收割机与天然存在的表面活性剂组合以获得所谓的最佳配方，在该最佳配方下乳液的稳定性最小。该配方的获得与加入破乳剂的亲水性和浓度有关，并概述了破乳过程的一般现象。
Water-in-oil emulsions formed during oil slicks or petroleum production are known to be stabilized by surfactant molecules that naturally occur in the crude oil, e. g., asphaltenes, which are quite lipophilic in nature. Demulsifier substances combine with naturally occurring surfactants to attain a so-called optimum formulation at which the stability of the emulsion is minimum. The attainment of this formulation is related to the hydrophilicity and concentration of the added demulsifier, and a general phenomenology of the demulsification process is outlined.
