  • Applications

    Octadecyl 2-hydroxybenzoate (CAS 14971-14-3) is primarily used as an emollient and slip agent in cosmetics and personal care, providing a smooth, conditioning feel in creams, lotions, and hair-care formulations. In perfumery, it can serve as a fragrance carrier and light fixative in certain systems, aiding the dissolution and even distribution of aromatic ingredients. It may also function as a plasticizer or lubricity additive in polymers and plastics, supporting processing and texture. In coatings and inks, it acts as a softening agent and processing aid to improve spread and handling. It is also used as an emollient additive in household cleaning products, helping reduce skin irritation during use. Usage is subject to local regulations and formulation limits.
