  • Applications

    Stearamidopropyl trimonium methosulfate (CAS 19277-88-4) is a cationic surfactant commonly used in cosmetic and personal care formulations as a conditioning agent and detangler for hair and skin, providing slip and reduced static; it also functions as a mild emulsifier and surface-active additive in cleansing products; in textiles and fabric care it can be used as a softening and conditioning agent for fibers; in coatings, inks and industrial formulations it serves as a surface-active additive to improve wetting, dispersion and compatibility; in polymer and plastics formulations it can act as a processing aid to enhance slip and compatibility; and in household and laundry products it contributes conditioning benefits at low concentrations.
