  • English Name: Stearyl trimethyl ammonium chloride.
  • Chemical Formula: C₂₁H₄₆ClN.
  • CAS No.: 112 - 03 - 8.
• Physical and Chemical Properties
  • Appearance: Usually white or light yellow solid.
  • Solubility: Easily soluble in hot water and ethanol, and will produce a large amount of foam when shaken.
  • Relative Density: 0.884.
  • HLB Value: 15.7.
  • Flash Point: The open - cup flash point is 180℃.
  • Surface Tension: The surface tension of a 0.1% solution is 34×10⁻³N/m.
  • Water - solubility: The solubility is <1% at 20℃.
  • pH Value: The pH value of a 10% aqueous solution is usually between 6.0 and 8.0.
• Chemical Stability: It has good chemical stability, and is heat - resistant, light - resistant and pressure - resistant. It also performs well in resisting strong alkalis and acids. However, it may decompose when heated at a temperature above 100℃ for a long time.
• Compatibility: It can be well - compatible with cationic and non - ionic surfactants or dyes, and produce a synergistic effect. However, it is prohibited to be compatible with anionic surfactants, dyes or auxiliaries, otherwise it may affect the product performance.
• Applications
  • Hair Care Products: It is one of the main components of hair conditioners. It can make hair soft and smooth, easy to comb, reduce static electricity, and play a role in conditioning and nourishing hair.
  • Emulsifier: It can be used as an excellent emulsifier for synthetic rubber, silicone oil, asphalt and chloroprene latex asphalt waterproof coatings, helping immiscible liquids to form a stable emulsion system.
  • Antistatic Agent: It is used in the synthetic fiber field, which can effectively reduce the static electricity accumulation on the fiber surface and improve the processing performance and service performance of the fiber.
  • Softener: It can be used as a softener for glass fiber and textiles, making the fiber fluffy and soft, and improving the wearing performance of the fabric.
  • Others: It can also be used in leather fatliquoring agents, latex product release agents and defoamers, as well as protein flocculation in the biopharmaceutical industry and water treatment flocculation.
• Packaging and Storage
  • Packaging: Generally, it is packed in 50 - kg plastic drums or 200 - kg drums.

  • Storage: It should be stored in a cool, dry and well - ventilated place, away from direct sunlight and high temperature. At the same time, it should be handled with care to prevent packaging damage.
