Abstract
A biodegradable lubricant which is prepared from: about 60-99 % by weight of at least one biodegradable synthetic ester base stock which comprises the reaction product of a branched or linear alcohol having the general formula R(OH)n, wherein R is an aliphatic or cyclo-aliphatic group having from about 2 to 20 carbon atoms and n is at least 2; and mixed acids comprising about 30 to 80 molar % of a linear acid having a carbon number in the range between about C5 to C12, and about 20 to 70 molar % of at least one branched acid having a carbon number in the range between about C5 to C13; wherein the ester base stock exhibits the following properties: at least 60 % biodegradation in 28 days as measured by the Modified Sturm test; a pour point of less than -25 °C; and a viscosity of less than 7500 cps at -25 °C; about 1 to 20 % by weight lubricant additive package;
and about 0 to 20 % of a solvent.
and about 0 to 20 % of a solvent.
