  • Applications

    Beta-Sitosteryl Acetate (CAS 915-05-9) is a waxy sterol ester used primarily in cosmetics and personal care as a skin-conditioning emollient and texture enhancer; it can also function as a slip agent and thickener in creams, lotions, and color cosmetics, and is sometimes evaluated for use in hair-care formulations to improve conditioning. In industrial manufacturing it may serve as a rheology modifier and lubricant in formulations, and in polymers/plastics and coatings it can act as a wax-like additive to adjust gloss and processing properties. Additionally, it may be employed as an intermediate or specialty ester in synthetic routes for other sterol derivatives. Applications are subject to local regulations and formulation limits.
