Abstract
A biodegradable penetrating lubricant, comprised of: (A) at least one triglyceride oil of the formula: wherein R1, R2, and R3 are aliphatic hydrocarbyl groups containing from about 7 to about 23 carbon atoms; (B) an organic solvent selected from the group comprising: (1) ethyl lactate, (2) methyl ester, and (3) combinations of 1 and 2; (C) an antioxidant; and, (D) a corrosion inhibitor. Optionally, the lubricant may further an additive selected from the group comprising: (E) a viscosity modifier; (F) an anti-wear inhibitor; and, (G) an emulsifier.
