>> Product Introduce

Octadecyl (Stearyl) Trimethyl Ammonium Chloride is a high-performance cationic surfactant, typically appearing as a white to pale yellow solid or waxy substance. It has moderate water solubility (better in hot water) and exhibits excellent softening properties, bactericidal activity, antistatic effects, and adsorption capacity. Stable under standard storage and application conditions, it is highly valued in industries requiring superior surface activity and conditioning effects.


>> Main Uses

  • Main Uses:Serves as a fabric softener, hair conditioner, bactericide, antistatic agent, and emulsifier. It also acts as a cationic modifier to enhance texture and adhesion in formulations.

  • Usage Scenarios:Widely used in the textile industry for softening and smoothing treatment of fabrics (especially chemical fibers, cotton, and wool) in personal care products (conditioners, hair masks, body lotions) to improve hair/skin softness and manageability in disinfectants for its broad-spectrum bactericidal activity and in coatings/inks as an emulsifier to stabilize formulations.
