  • Applications

    Isostearyl Isononanoate (CAS 163564-45-2) is a high-quality emollient ester widely used in cosmetics and personal care as a lightweight, non-greasy base oil that improves spreadability, skin feel, and binder compatibility in products such as lotions, creams, foundations, lip balms, and hair care formulations. It also serves as a solvent and carrier for fragrance oils in perfumery, helping dissolve and deliver aroma compounds in both leave-on and rinse-off products. In household products, it is used as a conditioning emollient and texture modifier in cleaners and dish liquids to impart slip and a smooth sensory feel. In coatings and inks, it can function as a processing aid or slip agent in certain formulations, aiding leveling and gloss without contributing significant polarity.
