  • Applications

    Cholesteryl undecanoate (CAS 24385-24-8) is a cholesterol ester with a wax-like lipid character commonly used in cosmetics and personal care as an emollient and structuring lipid to improve texture, spreadability, and moisture retention in creams, lotions, lip balms, and other moisturizers; it also acts as a thickener/structure agent for wax-based emulsions and solid formulations; in topical pharmaceutical formulations, it can serve as a lipid-based excipient or component of lipid delivery systems for semi-solid products; in coatings and industrial finishes, it may be used as a wax-like additive to enhance gloss, slip, and barrier properties; and in polymer or plastic formulations it can act as a wax-compatible additive to adjust melt rheology and hardness. Use should comply with local regulations and formulation limits.
