Abstract
The present invention is directed to a series of polyesters that are made by the reaction of a diacid with a pre-formed mono-hydroxy, di-hydroxy and optionally a tri-hydroxy ester of polyols selected from pentaerythritol, di pentearythritol trimethylolpropane and mixtures thereof. When reacted in the sequence shown, that is pre-formation of the mono-ester, di-ester and tri-ester, selection of the proper ratio of one to the other and then and only then reacted with the diacid, do these polyesters remain free of a gel and form cosmetically elegant oil phases.
