  • Applications

    2-Ethylhexyl caprylate (CAS 63321-70-0) is commonly used as an emollient in cosmetics and personal care, delivering light lubrication and a smooth skin feel. It also serves as a solvent and vehicle for fragrance oils in perfumery, and as a processing aid in coatings and inks to improve flow and film formation. In polymers and plastics formulations it can function as a plasticizer or processing solvent to modify flexibility and processing characteristics. It is employed as a carrier solvent in household cleaning products and other industrial formulations, and may be used as a compatible solvent or processing aid in adhesives and sealants, depending on formulation requirements.
