Claim:
A lubricating composition comprising one or more esters obtained as a reaction product of a reaction mixture comprising: a. a glycerol component, wherein said glycerol component comprises glycerol, glycerol oligomers, or combinations thereof and further wherein said glycerol oligomers comprise linear chains, branched chains, cyclic chains, or combinations thereof and further wherein said glycerol oligomers have at least 2 repeat glycerol units and further no more than about 32 repeat glycerol units; b. a fatty acid component comprising alkyl groups having at least about 8 carbon atoms and further wherein said alkyl groups have no more than about 32 carbon atoms; and c. a carboxylic acid component, wherein said carboxylic acid component has at least one carbon atom per molecule and no more than about 8 carbon atoms per molecule; wherein the fatty acid component comprises at least 50 percent by weight of the fatty acid component of oleic acid; wherein the fatty acid component comprises at least 5 percent by weight of the reaction mixture; and no more than about 40% by weight of the reaction mixture; and wherein the carboxylic acid component comprises at least about 0.1% by weight of the reaction mixture and no more than 20% of the reaction mixture.
