  A new compound that comprises a branched ester based primarily on renewable resources preferably has good friction properties, a low pour point; acceptable viscosity, and good thermal oxidative stability and is useful as a functional fluid such as a lubricant. The branched ester is a double ester of a polyhydric alcohol having at least two active hydrogen groups separated by at least one carbon atom, wherein each hydroxyl group of the polyhydric alcohol is esterified with one monobasic secondary hydroxy fatty acid group and each hydroxyl of a fatty acid is esterified with one alkyl or cycloalkyl monobasic carboxylic acid group that has from 2 to 22 carbon atoms.
