  • Applications

    Methylheptyl isostearate (CAS 209802-43-7) is a fatty ester primarily used as an emollient and solvent in cosmetic and personal care formulations. In perfumery, it serves as a solvent and carrier for fragrance ingredients, aiding solubility and texture. It is also used as a plasticizer and processing aid in polymers and coatings, contributing slip and compatibility in formulations. In coatings and inks, it may function as a processing solvent or slip agent to facilitate dispersion and application. Additionally, it is considered as an intermediate or formulation component in the industrial manufacturing of cosmetic ingredients, subject to local regulations and formulation limits.
