  • Applications

    Isostearyl Linoleate (CAS 127358-80-9) is commonly used as an emollient and skin-conditioning agent in cosmetics and personal care products, providing a smooth, easy spreadable feel. It often serves as a solvent or carrier for fragrance ingredients in perfumery and fragrance formulations, and can act as a slip agent and texture enhancer in coatings, inks, and adhesives. Because it is a fatty ester, it may also function as a processing aid or plasticizer in polymer systems to improve flexibility and handling characteristics.
