  • Applications

    Isostearamidopropyl ethyldimonium ethosulfate (CAS 67633-63-0) is a cationic surfactant and conditioning agent used in cosmetics and personal care, particularly in shampoos and conditioners to improve detangling, provide a smooth feel, and reduce static; it is also employed in household cleaning products as a surfactant and emulsifier to enhance cleaning performance and formulation stability; the compound can function as a fabric-softening aid in fabric-care formulations; in industrial contexts it can serve as a surfactant and emulsifier in polymer, coatings, and inks systems to improve wetting and emulsion stability, and may be evaluated for use in plastics and rubber processing. These applications are subject to local regulations and formulation limits.
