Abstract
Dimethicone copolyol sulfosuccinate compounds obtained from silicone-based monoesters. The dimethicone copolyol sulfosuccinates are obtained by reacting the ethoxylated polyether side chains of dimethicone copolyol with maleic anhydride to form a monoester and then converting the monoester to a sulfosuccinate by sulfonation of the double bond with a metallic sulfite, an amine or with a combination of a metallic sulfite and an amine. Dimethicone copolyol sulfosuccinates are silicone-based compounds which are useful as surfactants for improving the mildness and foam enhancing and stabilizing properties of shampoos and other personal care products.
