Patent ID: 8642520

Claim:
A lubricating composition comprising (a) about 62% to about 80% (wt/wt) of one or more silicones selected from the group consisting of dimethyl siloxane polymer and phenylmethyl dimethyl siloxane co-polymer, (b) about 10 to 30% (wt/wt) of an ester selected from the group consisting of (i) synthetic esters obtainable by reacting one or more aliphatic and aromatic polycarboxylic C 3-24 (COOH) x acid wherein x is 1-3, with one or more C 1-18 (OH) y alcohol wherein y is 1-6, to form a hydroxy polycarboxylic acid; and (ii) bio-based esters selected from vegetable oil and oils consisting of one or more triglycerides of formula IV wherein R 4 is a fatty acid residue independently selected from the group consisting of caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, palmitoleic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, gondoic acid, and erucic acid, wherein (ii) is bio-based triglyceride of formula IV wherein >60 mass percent (wt/wt) of the R 4 groups are derived from oleic acid, (c) about 2.5% (wt/wt) to about 12% (wt/wt) of an alkoxylated aliphatic polyamine derivative produce by reacting aliphatic polyamines with aliphatic C 2-12 1,2 epoxides.
