  • Applications

    Stearyl oleate (CAS 17673-49-3) is a wax ester widely used as an emollient and conditioning agent in cosmetics and personal care, providing a soft, silky feel in creams, lotions, and makeup. It is also used as a lubricant and processing aid in polymer and coating formulations, helping mold release and improving process rheology. Additionally, it can function as a plasticizer or additive in coatings, inks, and adhesives to enhance flexibility and gloss. In industrial and household products, stearyl oleate is commonly employed as a surface-conditioning and lubricating agent in cleaners, wax polishes, and surface-care formulations.
