Title: Method for demulsifying emulsions

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 C.sub.10-24 carboxylic acid ester derived by the addition of ethylene oxide and/or propylene oxide onto a ring opened epoxidized C.sub.10-24 carboxylic acid triglyceride which is ring opened with a C.sub.6-18 carboxylic acid; and (c) contacting the emulsion with a demulsifying effective amount of the alkoxylated C.sub.10-24 carboxylic acid ester.
