  • Applications

    Diethylaminoethyl stearate (CAS 3179-81-5) is used as an emollient and conditioning agent in cosmetics and personal care, providing slip and softness in hair care products and skin formulations. It also serves as an intermediate in the synthesis of cationic surfactants and can act as a plasticizer or processing aid in polymer, coatings, and adhesive formulations. As a fatty-ester surfactant, it may function as a nonionic surfactant or emulsifier in cleaning and household products. In coatings, inks, and adhesives, it can improve flow, wetting, and formulation stability. Depending on the formulation, it may be further quaternized or used to tune performance, subject to local regulations and formulation limits.
