Abstract
Novel polyoxyalkylene glycol esters prepared by the reaction of a polyoxyethylene glycol (PEG) or polyoxypropylene glycol (PPG) or mixtures thereof with shea butter, preferably mild-processed shea butter (MPSB) under specific mild-processing conditions. These materials 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 a water-soluble form that is substantive to the skin and hair.

- from about 2.0 to about 6.0% by weight C15H31;
- from about 25 to about 50% by weight C17H35;
- from about 40.0 to about 60.0% by weight C17H33;
- and
- (ii) a, b and c are independently integers ranging from 1 to 20.
