Technical di- and triglyceride mixtures

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,carboxylic acid ester derived by the addition of ethylene oxide and/or propylene oxide onto a ring opened epoxidized C,carboxylic acid triglyceride which is ring opened with a C,carboxylic acid; and (c) contacting the emulsion with a demulsifying effective amount of the alkoxylated C,carboxylic acid ester. Said process has application on crude oil emulsions.

Method for demulsifying emulsions

A process for cleaning boreholes, drilling equipment and drill cuttings is presented involving the application of a cleaning composition to surfaces and the subsequent removal of the cleaning composition and soils. The cleaning composition contains a cleaning additive having alkoxylation products obtained by the reaction of ethylene oxide, propylene oxide, butylene oxide or mixtures thereof with an OH-containing C,carboxylic acid or derivative thereof, where structural units corresponding to formula (I):

Use of biodegradable alcoxylation products for cleaning boreholes, boring instruments or borings

A concentrated aqueous pearlescent composition containing: (a) from 1 to 99.9% by weight of an ester formed by reacting a hydroxy-functionalized carboxylic acid with a fatty alcohol containing from 6 to 22 carbon atoms; (b) from 0.1 to 90% by weight of an emulsifier selected from the group consisting of an anionic surfactant, a nonionic surfactant, a cationic surfactant, an ampholytic surfactant, a zwitterionic surfactant, an esterquat, and mixtures thereof; and (c) up to 40% by weight of a polyol, all weights being based on the total weight of the composition.
