  • Applications

    (-)-Cholesteryl acetate (CAS 604-35-3) is used primarily as a lipid-derived emollient and structuring agent in cosmetics and personal care, helping to improve texture and skin feel; it may also serve as a lipid-based excipient or carrier in pharmaceutical formulations and specialized skincare products. In industrial coatings, inks, and adhesives, it can function as a wax-like additive to enhance slip and modulate crystallization in films and binders. In electronics and optical materials, (-)-Cholesteryl acetate may be employed as a chiral dopant in cholesteric liquid crystal systems to enable specialized display and photonic applications.
