A PROCESS FOR BREAKING PETROLEUM EMULSIONS OF THE WATER-IN-OIL TYPE, CHARACTERIZED BY SUBJECTING THE EMULSION TO THE ACTION TO A DEMULSIFIER INCLUDING A WATER-MISCIBLE OXYETHYLATED RICINOLEIC ACID-POLYCARBOCY ACID-GLYCEROL ESTER; SAID RICINOLEIC ACID ESTER CONTAINING AT LEAST ONE GLYCERYL RADIAL AS AN INTEGRAL PART THEREOF AND BEING THE ESTER OF A SATURATED POLYCARBOXY ACID HAVING NOT OVER 10 CARBON ATOMS; SAID ESTER BEING ADDITIONALLY CHARACTERIZED BY THE FACT THAT (A) THE TOTAL NUMBER OF RICINOLEIC ACID RADICALS IS LESS THAN THE HYPOTHETICAL NUMBER OF HYDROXYL RADICALS ORIGINALLY IN COMBINATION WITH A GLYCERYL RADICAL; AND (B) THE PRESENCE OF A REACTIVE HYDROXYL RADICAL; SAID HYDROXYL RADICAL BEING REACTIVE TOWARDS ETHYLENE OXIDE, AS DIFFERENTIATED FROM A RICIOLEYL HYDROXYL RADICAL, AND WITH THE FURTHER PROVISO THAT THE WEIGHT OF ETHYLENE OXIDE ADDED BY REACTION BASED ON THE WEIGHT OF SAID RICINOLEIC ACID-POLYCARBOXY ACID-GLYCEROL ESTER IS WITHIN THE RANGE OF 140% TO 200%.
