  • Applications

    Stearyl Heptanoate (CAS 66009-41-4) is a long-chain fatty ester widely used as an emollient and conditioning agent in cosmetics and personal care products, providing slip and a smooth feel on the skin. It also serves as a solvent or carrier for fragrance oils and cosmetic actives, helping to solubilize ingredients in formulations. In industrial applications, it functions as a plasticizer and lubricating additive in polymers and coatings, aiding processing and imparting flexibility. It may also be used as a processing aid or intermediate in chemical synthesis, and can act as a lubricating oil in some lubricant formulations. Its use is typically within formulation limits and subject to local regulations.
