Abstract
This invention relates to lubricant compositions comprising a polyalkylene glycol and an ester wherein the polyalkylene glycol has the formula (I): RO—(CH2CH(CH3)O)n—CH3 where R is an alkyl group with 1 to 15 carbon atoms and n=1 to 35. The lubricant compositions of the invention do not readily form stable emulsions with water. This feature makes the lubricant compositions of the invention particularly suitable for use with air compressors where it is very difficult to exclude moisture.
