Description

Alkylbenzyldimethylammonium Chlorides, Benzyl-C8-18-Alkyldimethyl is a versatile and widely used quaternary ammonium compound (quat) belonging to the benzalkonium chloride family. This cationic surfactant is valued for its potent antimicrobial, disinfectant, and surface-active properties, making it a critical component in formulations requiring biocidal efficacy and stability. It is essential for manufacturers in the disinfectant, personal care, water treatment, and industrial process chemical sectors seeking a reliable and effective active ingredient.

Application

• Disinfectants & Sanitizers: A key active ingredient in hospital-grade disinfectants, surface cleaners, and food-contact sanitizers due to its broad-spectrum efficacy against bacteria, fungi, and viruses.
• Personal Care & Cosmetics: Used as a preservative and antimicrobial agent in products like shampoos, creams, and lotions to prevent microbial spoilage.
• Water Treatment: Employed as a biocide and algaecide in industrial cooling towers, swimming pools, and wastewater systems.
• Industrial Biocides: Formulated into products for controlling microbial growth in fuel systems, paper mills, and metalworking fluids.
• Textile & Leather Processing: Acts as a softener, antistatic agent, and disinfectant in fabric finishing and leather treatment.
• Agriculture: Used in certain formulations as a disinfectant for agricultural equipment and facilities.
