Stearyl Trimethyl Ammonium Chloride CAS 112-03-8 Cationic Surfactant with Emulsifying Properties

Stearyl trimethyl ammonium chloride is a versatile cationic surfactant readily soluble in water. It possesses excellent surface-active, emulsifying, bactericidal, disinfectant, softening, and antistatic properties. This compound is widely used as an asphalt emulsifier, synthetic fiber antistatic agent, disinfectant, and fabric softener.

The product demonstrates outstanding stability and is utilized as an antistatic agent for textile fibers, hair conditioner, and emulsifier for asphalt, rubber, and silicone oil. It is also extensively employed in disinfectant formulations, with active ingredient concentrations typically exceeding 3-4% for asphalt emulsification and soil waterproofing applications.
