The invention relates to a composition preparation method for preparing a composition of estolides, the method comprising reacting an unsaturated compound of a type such as an acid or ester, with a saturated fatty acid; in the presence of a catalyst of a type such as sulphonic acid, the said method including no vacuum distillation step thereby making it possible to separate the monoestolides from the polyestolides. The invention also relates to a composition of estolides that is obtainable by the method according to the invention and the use thereof in lubricating compositions.

Estolide composition and process for making estolides

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.
