Polymeric castor polyester quaternary compounds based upon dimer acid
View Patent ↗The present invention deals with the certain castor polyesters that give high gloss when applied to the skin. Said ester are the reaction of the hydroxyl group of castor oil with less than one equivalent of a fatty acid then in a subsequently step the remainder of an equivalent of a diacid, in this case dimer acid.
