  • Applications

    Isotridecyl Stearate (CAS 31565-37-4) is widely used as an emollient and conditioning agent in cosmetics and personal care, providing a smooth, non-greasy skin feel and serving as a lightweight carrier oil in lotions, creams, and hair-care formulations. It is commonly employed as a solvent or carrier for fragrance components in perfumery and formulation blends. In industrial manufacturing, it can function as a plasticizer or processing lubricant in polymers and coatings to improve flexibility and handling. It is also used as a slip agent or lubricating component in adhesives and in some cleaning and household product formulations. Use is formulation-dependent and subject to local regulations.
