  • Applications

    Hexyldecyl Ethylhexanoate (CAS 439134-25-5) is a long-chain ester commonly used in cosmetics and personal care as an emollient and solvent, delivering slip, conditioning, and improved spreadability in creams, lotions, and color cosmetics. In perfumery, it acts as a fragrance solvent and carrier, helping to dissolve aroma ingredients and assist fragrance deposition on skin or fabrics. In coatings, inks, and adhesives, it functions as a processing solvent and plasticizer, aiding film formation and flexibility. In household products and cleaners, it serves as a solvent and texture enhancer, improving formulation handling and product feel. In polymers and plastics, it can be used as a processing aid or lubricant to enhance processing or compatibility with other additives.
