  • Applications

    Stearyl ethylhexyldimonium methosulfate (CAS 463965-15-3) is a quaternary ammonium surfactant widely used as a conditioning agent and softening surfactant in cosmetics and personal care products, including hair care and skin care formulations; it also serves as an emulsifier and surfactant in such products; in addition, it is used as an antistatic and slip agent in textile finishing and fabric care; its surface-active properties make it a useful additive in coatings, inks, and paints to improve wetting and dispersion; in polymer/plastics processing, it can act as a processing aid to improve slip and compatibility. Use is subject to local regulations and formulation limits.
