1. Acts Octadecyl trimethyl ammonium chloride CAS 112-03-8 as a high-efficiency cationic surfactant in industrial production, providing excellent softening, antistatic and emulsifying effects for textile finishing and fabric care processes.

2. Serves Octadecyl trimethyl ammonium chloride as a key bactericide and scale inhibitor in water treatment, effectively suppressing bacteria, algae growth and scale formation in industrial circulating water systems.

3. Functions as a functional additive in plastic and coating formulations, enhancing surface smoothness and antistatic performance of polymer and coating products efficiently.

Store Octadecyl trimethyl ammonium chloride (CAS 112-03-8, white waxy solid/pale yellow viscous liquid, faint amine odor, combustible) at 10–25°C in sealed HDPE containers in a cool, dry, well-ventilated area. Isolate from strong oxidants, acids, alkalis and anionic surfactants to avoid decomposition and performance failure. Wear nitrile gloves, safety goggles and a face mask; avoid skin/eye contact, dust/vapor inhalation and ingestion to prevent mild corrosive irritation. Reseal tightly post-use; dispose of waste per local quaternary ammonium salt & surfactant chemical regulations.

Octadecyl trimethyl ammonium chloride is an industrial cationic surfactant and water treatment agent, not for direct pure-form human contact or ingestion; undiluted contact may cause skin and mucosal irritation, and intake will lead to severe gastrointestinal discomfort.

In regulated applications, Octadecyl trimethyl ammonium chloride CAS 112-03-8 features superior long-chain surface activity and stable performance, delivers durable softening and antistatic effects, and has good compatibility with most cationic/non-ionic industrial formulation systems.
