Description

Dodecyldimethylbenzylammonium Chloride is a quaternary ammonium compound (QAC) widely recognized for its potent antimicrobial and surfactant properties. This versatile chemical is a critical component in formulations requiring effective disinfection, microbial control, and surface activity. It serves as an essential raw material for manufacturers in the disinfectant, sanitizer, personal care, water treatment, and textile processing industries, where reliable performance and quality are paramount.

Application

• Disinfectant & Sanitizer Formulations: A key active ingredient in hospital-grade disinfectants, surface cleaners, and food-contact sanitizers for its broad-spectrum efficacy against bacteria, viruses, and fungi.
• Algaecides & Biocides: Used in industrial water treatment systems, cooling towers, and recreational water to control algae and microbial growth.
• Personal Care Products: Employed as a preservative and antimicrobial agent in cosmetics, shampoos, and lotions.
• Textile & Leather Processing: Functions as a softening agent, antistatic agent, and biocide in fabric finishing and leather treatment.
• Oilfield & Industrial Biocides: Applied in drilling muds and industrial process fluids to prevent bacterial contamination and souring.
• Agricultural Adjuvants: Used as a surfactant to enhance the spreading and adhesion of pesticides and herbicides.
