Hexyldecyl stearate is an ester of stearic acid and hexyldecanol, widely used as an emollient and skin-conditioning agent. It provides a silky, smooth texture and imparts a non-greasy, lightweight feel to formulations. Known for its excellent spreadability, it enhances the sensorial profile of creams, lotions, and makeup products. Its film-forming and moisturizing properties make it a popular choice in skincare, hair care, and sun care applications.
