ABSTRACT:
An oxidatively stable biodegradable industrial fluid is disclosed, wherein the industrial fluid is comprised of an epoxidized vegetable oil or synthetic ester in combination with at least one antioxidant. A method for improving the oxidation stability of industrial fluids is also disclosed and comprises employing as the base oil of said hydraulic fluid an epoxidized synthetic ester in combination with at least one antioxidant.
