Chemical Properties:

  1. solid
  2. STAC has good compatibility with cationic, non-ionic and amphoteric surfactants, and has excellent penetration, softness, emulsification, antistatic, biodegradability and bactericidal properties.
  3. STAC is a light yellow colloidal liquid. The relative density is 0.884, the HLB value is 15.7, the flash point (open cup) is 180°C, and the surface tension (0.1% solution) is 34×10Chemicalbook-3N/m. When the water solubility is 20℃, the solubility is less than 1%. Soluble in alcohol. It has excellent stability, surface activity, emulsification, sterilization, disinfection, softness, and antistatic properties.
  4. STAC cationic surfactant, widely used in asphalt emulsification and waterproof coating emulsification, silicone oil emulsification, hair conditioner and cosmetics emulsification conditioning, fabric fiber soft and antistatic, organic swelling Chemicalbook soil modification, protein flocculation and water treatment flocculation in the biopharmaceutical industry, Glass fiber soft processing, anti-burn treatment agent for nylon parachute surface, as well as bactericide and disinfectant, etc.
  5. STAC passes octadecyl tertiary amine into the autoclave, adds a proper amount of isopropanol and does not serve as the reaction medium, and then adds a small amount of sodium hydroxide as a catalyst. After replacing the air in the kettle with nitrogen, the temperature was raised to 50°C, and 1% (mass) excess of methyl chloride over the theoretical Chemicalbook was introduced. Close the autoclave. React for 4h at 0.5MPa. The reaction is over. After desalting, dilute with water to the required concentration. The discharging tank is the finished product.


  1. STAC has good chemical stability and is widely used in hair conditioners, fabric softeners, fiber antistatic agents, silicone oil emulsifiers, asphalt emulsifiers, organic bentonite modifiers, disinfectants, protein flocculants and water in the biopharmaceutical industry Treatment of flocculants, etc.
  2. STAC is used as an antistatic agent for textile fibers, a hair conditioner, and an emulsifier for asphalt, rubber and silicone oil. And it is widely used as a disinfectant.
  3. STAC is used as a fabric softener to make the fiber bulky and soft to the touch. It is used for the emulsification of asphalt and the raw material of hair conditioner.
