  • Applications

    Ethylhexyl Isostearate (CAS 81897-25-8) is widely used as an emollient in cosmetics and personal care, delivering a soft, conditioning feel and helping moisturization; it also serves as a solvent or carrier for fragrances in perfumery; in coatings and inks it acts as a plasticizer and processing aid to improve slip, flexibility, and compatibility with film-forming systems; in polymer and plastic formulations it can function as a plasticizer or processing aid to adjust flexibility and mechanical properties; in cleaning and household formulations it can serve as a light solvent or carrier for active ingredients; in adhesives and related emulsion systems it may be used as a lubricating-like additive to improve flow and compatibility.
