  • Applications

    Isopropyl Stearate (CAS 112-10-7) is a lightweight fatty ester widely used as an emollient and vehicle in cosmetics and personal care formulations, providing slip and a non-greasy skin feel. It also functions as a solvent/carrier for fragrances and active ingredients, enabling smooth dispersion in lotions, creams, and fragrance products. In pharmaceutical topical applications, it can serve as an inert excipient and solvent. In industrial manufacturing, it acts as a processing aid and slip agent in coatings, inks, and plastics formulations, facilitating handling and blending. It is also used as a conditioning component in some household cleaning formulations.
