摘要:
The present invention discloses an improved food-grade-lubricant useful as hydraulic oil, circulating oil, drip oil, general purpose oil, grease base oil, cable oil, chain oil, spindle oil, gear oil, and compressor oil for equipment in the food service industry. The lubricant comprises at least one vegetable oil, at least one polyalphaolefin, and at least one antioxidant. The lubricant has improved properties when subjected to thermal and mechanical stress.
摘要:
A biodegradable penetrating lubricant, comprised of: (A) at least one triglyceride oil of formula (I), wherein R , R , and R 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.

摘要:
A lubricant composition is disclosed which comprises, a triglyceride oil lubricant and an oil soluble copper compound antioxidant. The oil soluble copper compounds are particularly effective antioxidants for triglycerides. The lubricant composition can include soluble zinc compounds which reduce wear and/or soluble antimony compounds which reduce wear and can function as adjuvant antioxidants reducing the amount of oil soluble copper required. Preferred zinc and antimony compounds are zinc dithiophosphate antiwear/antioxidant, and antimony dialkyldithiocarbamate antioxidant adjuvant.
