Used primarily as a biocide and antimicrobial agent in industrial water treatment systems. Effective in controlling the growth of bacteria, algae, and fungi in cooling towers, paper mills, and oilfield systems. Also utilized as a disinfectant in household and institutional cleaning products due to its broad-spectrum antimicrobial activity. Its quaternary ammonium structure enhances surface adhesion, making it suitable for use in fabric softeners and personal care products where sustained antimicrobial action is required. Stable over a wide pH range and compatible with many surfactants and formulation components.
