  • Applications

    Propyl laurate (CAS 3681-78-5) is a fatty ester of lauric acid and propanol, commonly used as an emollient and solvent in cosmetic and personal care formulations such as creams, lotions, and shampoos; it can also function as a solvent and carrier for fragrance oils in perfumery; in household cleaning products, it serves as a solvent for poorly soluble ingredients; and in pharmaceutical topical formulations, it may be used as an excipient or lipophilic solvent.
