Abstract:
1. A metal processing lubricant composition comprising a polyhydrocarbyl ester of an aliphatic polyol, wherein at least one hydrocarbyl group of the polyhydrocarbyl ester comprises 6-14 carbon atoms, other hydrocarbyl groups of the polyhydrocarbyl ester comprise 6-20 carbon atoms, the polyhydrocarbyl ester has a kinematic viscosity (40° C.) of 20-100 cSt, a molar equivalent of hydrocarbyl groups having 6-14 carbon atoms per mol aliphatic polyol in the polyhydrocarbyl ester is between 1.5 to 4.0, and wherein the aliphatic polyol comprises 2-12 OH groups and 2-12 carbon atoms.
