  • Applications

    Isostearyl Myristate (CAS 72576-81-9) is the ester of isostearyl alcohol and myristic acid and is widely used as an emollient and solvent in cosmetics and personal care. In cosmetic formulations, it provides slip, improves spreadability, and yields a smooth, non-greasy skin feel, while also serving as a carrier for active ingredients and fragrance oils. In perfumery, it acts as a neutral solvent and fragrance carrier. In hair care products it functions as a conditioning base that enhances combability and texture. In some industrial formulations, it can act as a lubricating oil or processing aid and may serve as a lightweight plasticizer or diluent in polymers, coatings, or adhesives.
