Abstract
Novel silicone compounds prepared by the reaction of a dimethicone copolyol with shea butter, preferably mild-processed shea butter (MPSB). These compounds are useful as cosmetic and personal care ingredients, allowing for the delivery of highly desirable active ingredients present in shea butter, including natural antioxidants, in compounds are substantive to the skin and hair.
