Abstract

See full text

The disclosure relates to a lubricating composition consisting essentially of a decarboxylated rosin acid (DCR), a base oil, and optional additives, and methods for using same. The decarboxylated rosin acid has a density of 0.9 to 1.0 g/cm3 at 20° C., a viscosity of 15 to 60 cSt at 40° C., and an acid value of <50 mg KOH/g. The lubricating compositions containing the DCR is characterized as having improved anti-wear and friction reducing properties, as well as improved electrical properties, and cooling performance for use in electric and hybrid vehicles. In embodiments, the lubricating composition exhibits a wear scar diameter of <350 μm, according to ASTM D6079.
