  • Applications

    Oleyl palmitate (CAS 2906-55-0) is a fatty ester used primarily as an emollient and base oil in cosmetics and personal care, providing slip and moisturization in creams, lotions, lip care, and other skin-care formulations. It also serves as a carrier or solvent for fragrance ingredients and other actives in oil-based formulations. In polymer and plastics applications, it can act as a plasticizer or lubricating additive in polymer blends and wax systems. In coatings, inks, and adhesives, it is used as a processing aid to improve gloss, slip, and handling properties. In pharmaceutical topical formulations, it may function as a vehicle/emollient component in emulsions or gel-based dosage forms, subject to local regulations and formulation limits.
