  • Applications

    Oleic acid, butyl ester (CAS 142-77-8), also known as butyl oleate, is used mainly as an emollient, solvent, and processing aid in a range of formulations. In cosmetics and personal care, it often serves as a skin-conditioning agent and a light solvent in creams, lotions, and related products. In perfumery, it is commonly used as a fragrance carrier and solvent for essential oils and aroma compounds. In coatings and inks, it can function as a plasticizer and solvent to improve flexibility and processability. In polymers and plastics, it is employed as a plasticizer for PVC and other polymers to enhance flexibility. In cleaning and detergent formulations, it may act as a solvent carrier and auxiliary ingredient to aid formulation and cleaning performance. In industrial manufacturing, it may serve as a light lubricant or processing aid to ease blending and reduce viscosity.
