Description

Benzyldimethyldodecylammonium Bromide is a high-purity quaternary ammonium compound (QAC) widely recognized for its potent antimicrobial and surfactant properties. This versatile chemical is essential for formulators requiring reliable biocidal activity and cationic surface modification. It serves as a critical raw material for manufacturers in the disinfectant, personal care, textile, and water treatment industries, where performance and consistency are paramount.

Application

• Disinfectant & Sanitizer Formulations: A key active ingredient in hospital-grade disinfectants, surface cleaners, and hand sanitizers for its broad-spectrum efficacy against bacteria, viruses, and fungi.
• Personal Care Products: Used as a preservative and conditioning agent in cosmetics, shampoos, and hair conditioners.
• Textile & Leather Processing: Functions as a softener, antistatic agent, and dye-fixing auxiliary in fabric treatment.
• Water Treatment: Employed as an algicide and biocide in industrial cooling towers and water systems.
• Oilfield Chemicals: Acts as a corrosion inhibitor and biocide in drilling and production fluids.
• Paper Manufacturing: Serves as a retention aid, drainage aid, and biocide in pulp and paper processes.
• Research & Development: Used as a phase-transfer catalyst and surfactant in organic synthesis and pharmaceutical research.
