Abstract
A process for breaking an emulsion into a water phase and an oil phase involving: (a) providing an emulsion containing an oil phase and a water phase; (b) providing an alkoxylated C10-24 carboxylic acid ester derived by the addition of ethylene oxide and/or propylene oxide onto a ring opened epoxidized C10-24 carboxylic acid triglyceride which is ring opened with a C6-18 carboxylic acid; and (c) contacting the emulsion with a demulsifying effective amount of the alkoxylated C10-24 carboxylic acid ester. Said process has application on crude oil emulsions.
