Description

Alkyl(C12-18) Dimethyl Benzyl Ammonium Chloride is a high-purity quaternary ammonium compound (quat) widely recognized for its potent antimicrobial and surfactant properties. This versatile chemical is essential for formulating effective disinfectants, sanitizers, and industrial biocides that require broad-spectrum efficacy and stability. It is a critical raw material for manufacturers in the hygiene, institutional cleaning, water treatment, and agricultural chemical sectors seeking reliable, high-performance active ingredients.

Application

• Disinfectant & Sanitizer Formulations: Primary active ingredient in hospital-grade disinfectants, surface cleaners, food contact sanitizers, and algaecides.
• Water Treatment: Used as a biocide and algistat in industrial cooling towers, swimming pools, and process water systems.
• Agricultural Adjuvants: Serves as a surfactant and emulsifier in pesticide and herbicide formulations to enhance spreading and adhesion.
• Personal Care & Cosmetics: Employed as a preservative and conditioning agent in shampoos, creams, and other leave-on/rinse-off products.
• Textile & Leather Processing: Acts as a softener, antistatic agent, and biocide in fabric finishing and leather treatment baths.
• Oilfield & Industrial Biocides: Controls microbial growth (bacteria, fungi) in drilling muds, fracturing fluids, and metalworking fluids.
