Cetyl Palmitate
Cetyl Palmitate is a naturally derived ester formed by the reaction of cetyl alcohol and palmitic acid. It appears as a white to off-white waxy solid with a mild fatty odor. This compound is widely used in cosmetic, pharmaceutical, and industrial formulations for its emollient, thickening, and texture-enhancing properties. Cetyl Palmitate imparts a smooth, creamy feel to products and contributes to improved stability and consistency in creams, lotions, balms, and ointments. Its film-forming and skin-conditioning attributes make it a preferred ingredient in personal care products as well as in specialty industrial applications.
