Benzalkonium chloride is a cationic surfactant classified as a non-oxidizing bactericide. It exhibits broad-spectrum and high-efficiency bactericidal and algaecidal capabilities, effectively inhibiting the reproduction of bacteria, algae, and the growth of slime in water systems. Additionally, it possesses excellent slime stripping properties, moderate dispersion and penetration effects, as well as certain oil-removing, deodorizing, and corrosion-inhibiting functionalities.
