Diisostearoyl Trimethylolpropane Siloxy Silicate
What is Diisostearoyl Trimethylolpropane Siloxy Silicate?
Diisostearoyl Trimethylolpropane Siloxy Silicate is a synthetic silicone derivative featuring a siloxy silicate backbone esterified with isostearic acid and trimethylolpropane. This branched polymer structure distinguishes it within cosmetic silicones. Commonly incorporated into makeup products such as foundations, lipsticks, and mascaras, as well as select skincare items, it serves as an emollient and film-former. In formulations, it promotes even application by improving pigment dispersion and oil compatibility. Upon skin contact, it creates a breathable, flexible film that enhances product longevity, imparts a non-tacky smoothness, and supports a matte-to-satin finish. Its low viscosity aids in reducing greasiness while allowing better blendability, making it suitable for long-wear cosmetics without heaviness.
