  • Applications

    Isobutyl Palmitate, CAS 110-34-9, is commonly used as an emollient and solvent in cosmetics and personal care products, providing conditioning properties in creams, lotions, and hair care formulations. In perfumery, it serves as a solvent and carrier for fragrance ingredients and actives, aiding fragrance delivery and compatibility. In coatings, inks, and adhesives used in industrial manufacturing, it functions as a processing aid and plasticizer for polymers, as well as a lubricant to improve handling of formulations. It is also used as a conditioning oil and solvent in some cleaning formulations and household products. Use is subject to local regulations and formulation limits.
