  • Applications

    Fatty acids, C16-18 and C18-unsatd., 2-ethylhexyl esters (CAS 85049-37-2) are widely used as emollients and solvents in cosmetics and personal care, providing a smooth, spreadable feel in moisturizers and other skin-care products; they act as plasticizers and processing aids in polymers and coatings, improving flexibility in plastics such as PVC; they serve as lubricants and slip agents in industrial formulations; they function as solvents/vehicles for fragrances, flavors, and active ingredients in perfumery, flavor, and cleaning products; they are used as carriers/dispersion aids in coatings, inks, and adhesives to enhance dispersion and formulation stability.
