Abstract
The invention discloses novel series of silicone polyesters which are useful as humectants for softening, conditioning and lubricating hair and skin. Compounds of the invention by are prepared by the esterification of (a) a hydroxyl containing silicone compound selected from silanol and dimethicone copolyol (b) a diacid and (c) a poly-hydroxy compound selected from the group consisting of glycerine, methyl glucoside, sorbitol and their alkoxylates and (d) optionally a fatty acid. The polyesters of the present invention allow for the formulation of personal care products in which the humectant is substantive to the hair and skin by virtue of the structure of the polyester and can be formulated into a variety of products for delivery to hair and skin.
