>> Product Introduce

Dioctadecyl Dimethyl Ammonium Chloride is a high-performance cationic surfactant with ultra-long hydrophobic chains (C18). Due to its extended alkyl structure, it exhibits exceptional surface adsorption capacity, strong film-forming properties, and superior persistence in applications. It has limited solubility in cold water but dissolves in hot water or organic solvents (e.g., ethanol, chloroform). Its ultra-long chains enable strong binding to negatively charged surfaces (e.g., fibers, skin, metal), delivering long-lasting antimicrobial activity, premium softening effects, and durable antistatic performance—making it ideal for high-end scenarios requiring sustained efficacy.


>> Main Uses

  • Main Uses:Functions as a premium long-acting fabric softener, high-end hair/skin conditioner, persistent antimicrobial agent, durable antistatic modifier, and surface film-forming additive.

  • Usage Scenarios:Widely used in the textile industry for softening high-grade fabrics (e.g., wool, silk, luxury cotton) to enhance long-term suppleness and smoothness in personal care products (e.g., high-end hair conditioners, moisturizing lotions) as a conditioning agent to improve texture and reduce friction in coatings and plastics as an antistatic additive and antimicrobial preservative to prevent static buildup and microbial degradation in leather processing for premium softening and anti-mold finishing and in specialty industrial formulations as a lubricant additive for metal processing, leveraging its film-forming properties to reduce wear.
