  • Applications

    Ethyl arachidate is a high-molecular-weight fatty ester used primarily as an emollient and slip agent in cosmetics and personal care products, providing conditioning properties in skin and hair formulations. It also acts as a non-volatile solvent and fragrance carrier in perfumery, aiding the dissolution and distribution of aroma compounds. In polymers and coatings, it serves as a plasticizer and wax-like additive to improve processing, gloss and film properties. In industrial manufacturing, it is used as a processing aid and lubricant component in lubricants and metalworking fluids to reduce friction and improve stability.
