  • Applications

    2-Phenylethyl lactate, CAS 155449-46-0, is a lactate ester with a light floral aroma used across several industries. In perfumery, it serves as a fragrance ingredient and can act as a fixative to help odors last longer. In cosmetics and personal care, it functions as a mild solvent and fragrance carrier for products such as moisturizers and fragrances. In coatings and inks, it can act as a solvent or processing aid, supporting formulation and controlling evaporation. In adhesives and polymers, it may serve as a plasticizer or processing aid to improve flexibility and handling. In flavor applications, it may be evaluated as an aroma constituent within flavor formulations, subject to regulatory limits.
