Benzalkonium chloride belongs to the category of cationic surfactants and non‑oxidizing biocides. It shows strong broad‑spectrum activity against various bacteria and algae. This compound effectively inhibits microbial growth and removes biofilm and slime in water systems, while also providing excellent stripping, dispersing, and penetrating effects. It additionally supports degreasing, deodorization, and corrosion inhibition. With low toxicity, non‑bioaccumulative properties, and good water solubility that is not affected by water hardness, it is widely used in industrial circulating water systems in petroleum, chemical, power, and textile industries to control sulfate‑reducing bacteria. It also acts as a multifunctional additive in textile processing as a softener, antistatic agent, and emulsifier, and is used as a preservative in disinfectant wipes.

Benzalkonium chloride is widely used for disinfection in industrial water systems such as factory cooling systems, power plant water networks, paper production processes, and oilfield injection systems. It is also applied for the sanitization of medical equipment and public facilities including swimming pools and laundry facilities. In the food industry, it serves as a safe and effective disinfectant for processing equipment. In the textile industry, it is used as a leveling agent, antimicrobial agent, softener, antistatic agent, emulsifier, and finishing agent in dyeing and printing processes.
