  • Applications

    2-Ethylhexyl isohexadecanoate (CAS 93843-32-4) is primarily used as a plasticizer for PVC and other polymers to impart flexibility to films, coatings, and adhesives; it also serves as a lubricant and processing aid in polymer compounding; in cosmetics and personal care, it functions as an emollient and solvent carrier for active ingredients and fragrances; in industrial applications such as coatings, inks, and cleaning formulations, it can act as a high-boiling solvent or carrier; and, as a long-chain fatty ester, it is sometimes used as an intermediate in the synthesis of other esters or specialty lubricants.
