  • Applications

    18:2 Campesteryl ester (CAS 86248-87-5) is a plant sterol ester used as a wax-like lipid and emollient in cosmetics and personal care, improving spreadability and skin feel in creams, lotions, and hair-care products; it also acts as a structuring and stabilizing lipid for oil-in-water and water-in-oil emulsions. It may be used as a lipid additive in household and cleaning products, contributing to formulation rheology. In polymer and coatings formulations, it can serve as a lipid-based additive to adjust crystallinity, lubrication, or compatibility of lipid-rich systems. In industrial manufacturing, it can be used as a lipid-based additive or thickener in specialized formulations. Overall, its role is as a sterol ester with lipid-like functionality that supports texture, stabilization, and lubrication in specialized formulations, subject to local regulations and formulation limits.
