Abstract
A grease composition is disclosed, having from 50 to 99 weight percent of a lubricating base oil, from 1 to 30 weight percent of a thickener component including one or more of (i) one or more natural oil derivatives selected from the group consisting of triglycerides, diglycerides, monoglycerides, or oligomers therefrom, fatty acid methyl esters and corresponding fatty acids, salts, and dibasic esters therefrom, and C10-C15 esters, C15-C18 esters, or C+ diesters, or diesters therefrom, (ii) one or more carboxylic acids and/or derivatives thereof, and (iii) one or more of a metal base compound, and from 1 to 15 weight percent of one or more optional additives. Processes for making grease compositions are also disclosed.

A grease composition comprising:
- (a) from 50 to 99 weight percent of a lubricating base oil,
- (b) from 1 to 30 weight percent of a thickener component comprising one or more of (i) one or more natural oil derivatives selected from the group consisting of triglycerides, diglycerides, monoglycerides, or oligomers therefrom, fatty acid methyl esters and corresponding fatty acids, salts, and dibasic esters therefrom, and C10-C15 esters, C15-C18 esters, or C18+ esters, or diesters therefrom, (ii) one or more carboxylic acids and/or derivatives thereof, and (iii) one or more of a metal base compound;
- and
- (c) from 1 to 15 weight percent of one or more optional additives.
A grease composition comprising:
- (a) about 75 to 85 weight percent of a lubricating base oil comprising a polyalphaolefin base oil,
- (b) about 15 to 25 weight percent of a thickener component comprising one or more of (i) one or more natural oil derivatives comprising esters comprise octadecanedioic acid dimethyl esters, (ii) one or more carboxylic acids comprising 12-hydroxystearic acid, and (iii) one or more of a metal base compound comprising lithium hydroxide;
- and
- (c) from 1 to 15 weight percent of one or more optional additives selected from the group consisting of metal deactivators, antioxidants, antiwear agents, rust inhibitors, viscosity modifiers, extreme pressure agents, and corrosion inhibitors.
