Application of Carboxyl Modified Silicones to Cosmetic Surfactants

Abstract

The application of carboxyl modified silicones as a surfactant was studied. Carboxyl modified silicones, which were neutralized with triethanolamine, were used in this study. The results of a emulsification test of dimethylpolysiloxane indicated that both water-in-oil and oil-in-water emulsions could be prepared by changing carboxyl equivalents. In particular, a high internal phase water-in-oil emulsion was formed by using a high-equivalent carboxyl modified silicone. On the other hand, an aqueous solution of neutralized low-equivalent carboxyl modified silicone showed good detergency for a spot of decamethylcyclopentasiloxane. These results suggest that carboxyl modified silicones are valuable for cosmetics.
