  • Applications

    Stearamidopropyl ethyldimonium ethosulfate (CAS 67846-16-6) is a cationic surfactant commonly used as a conditioning agent in cosmetics and personal care, providing hair and skin conditioning and aiding emulsion stability in lotions and creams; it also serves as a fabric-softening and anti-static additive in textiles, and acts as a functional surfactant to improve wetting, dispersion, and film formation in coatings and inks; it may also function as a processing aid or compatibilizer in polymer formulations.
