Abstract
The present invention is directed to a series of polymeric citrate esters that have unique liquidity, and outstanding feel when applied to the skin. The polymers of the present invention are made by polymerizing citrate mono and di fatty esters with a hydroxypropyl functional silicone to provide a polymer with a very low surface tension and outstanding skin feel.
