  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.

  Gels, stable at a predetermined service temperature and formed from silicone solvent fluids and a solute gelator, are disclosed. The solute gelator is selected from stearic acid; 12-hydroxystearic acid; metal salts of 12-hydroxy- stearic acid; metal salts of stearic acid and admixtures thereof. The solute gelator is dissolved in the silicone solvent and forms a solution therewith that is supersaturated at the predetermined service temperature. The gelator is then precipitated from the solution, forming a three- dimensional fibrous network that imparts sufficient mechanicl properties to the silicone solvent to form a gel.
