  • Applications

    2-Ethylhexyl propionate is used primarily as a solvent and fragrance carrier in perfumery, and as a component in cosmetics/personal care where it helps dissolve and transport fragrance oils. It also acts as a plasticizer for various polymers and as a processing solvent in coatings, inks, and adhesives. In household products and cleaners, it serves as a solvent and fragrance carrier; in industrial manufacturing it is used as a processing aid or diluent in formulation systems.
