>> Product Introduce

Hexadecyl (Cetyl) Trimethyl Ammonium Chloride is a high-performance cationic surfactant, typically appearing as a white to off-white solid or waxy paste with excellent water solubility. It exhibits strong surface activity, superior softening effects, bactericidal properties, and antistatic capabilities. Stable under standard storage and application conditions, it is widely trusted in industrial and daily chemical fields for its reliability.


>> Main Uses

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

  • Usage Scenarios:Applied in the textile industry for softening and antistatic treatment of fabrics (e.g., cotton, wool) in personal care products (shampoos, conditioners, hair masks) as a conditioning agent to improve hair smoothness in disinfectants for its broad-spectrum bactericidal activity and in cosmetic formulations to boost emulsion stability.
