ABSTRACT:
The invention involves the use of biodegradable polyalpha olefins ("PAOs") to treat biodegradable industrial fluids, such as lubricants, hydraulic fluids, fuel oils, and the like, to: (a) reduce their pour point; (b) improve their oxidation stability performance; and/or, (c) improve their hydrolytic stability performance. A preferred industrial fluid is mixture of vegetable oil and branched alkane where the average molecular weight of the alkane is about 200-400, and the alkane additionally has a sufficient degree of branching to have a pour point of about -25.degree. C. or lower.
