METHOD FOR PRODUCING ESTOLIDE ESTERS AND COMPOSITION OF ESTOLIDE ESTERS

The invention relates to a method for the preparation of estolide esters from a hydroxycarboxylic acid by a reaction of addition of a fatty acid to the hydroxyl function and by a reaction of esterification of the carboxylic acid function with an alcohol. The invention further relates to the use of estolide esters as a base oil in a lubricating composition or as an emollient in a cosmetic or pharmaceutical composition.
