  • Applications

    Chemical name 2-Ethylhexyl caprate (CAS 73947-30-5) is widely used as an emollient and solvent in cosmetic and personal-care formulations, delivering a light, non-greasy slip and skin-conditioning properties. It serves as a carrier and solvent for fragrance oils in perfumery, helping dissolve and stabilize aroma components. In coatings and inks, it acts as a low-volatility processing solvent and plasticizer/diluent to improve flow and film formation. It is also used in household and industrial cleaners as a non-polar solvent and diluent. In polymers and plastics processing, it may function as a processing aid or plasticizer to modulate viscosity and flexibility. Additionally, it may be used as a solvent or carrier in topical pharmaceutical formulations, subject to regulatory constraints.
