    Abstract: The present invention relates to certain reconstituted wax esters, prepared by the reaction of a silianol polymer and a natural high molecular wax ester selected from the group consisting of beeswax, candelillia, and carnauba wax. These materials are useful in preparation of cosmetic products where their ability to couple organic, silicone and other components into a uniform mass is unsurpassed. One major area for the use of these materials is in lipsticks. In addition they are useful in antiperspirants and other formulations which contain both oils and silicones.
