  • Applications

    Isobutyl myristate (CAS 25263-97-2) is a non-ionic ester commonly used in cosmetics and personal care as an emollient and solvent, providing a light, non-greasy skin feel and aiding dispersion of active ingredients. In perfumery, it acts as a fragrance carrier and can help dissolve and blend volatile aroma compounds. It is also used in household products as a solvent and fragrance carrier, contributing to product texture and scent release. In industrial manufacturing, it functions as a processing aid and solvent for resins and inks, and in polymer and plastics formulations as a plasticizer/diluent to adjust viscosity and flexibility. In some cases it is employed as an intermediate in chemical synthesis and formulation development.
