  • Publication number: 20090285876
    Abstract: The invention provides a composition comprising reaction products from a reaction of a natural butter or natural oil such as shea butter with glycerin in the presence of a basic catalyst and wherein the reaction products retain the unsaponifiable portion of said natural butter or natural oil. The resulting reaction products are self-emulsifiable and are particularly useful in personal care, cosmetic, pharmaceutical, paper and textile applications.
