Hypochlorous acid (HClO) has a strong oxidizing effect. After contact with microorganisms, hypochlorous acid can quickly destroy the cell membrane of microorganisms and destroy the spikes of viral proteins adsorbed on the cell membrane, such as E. coli, Staphylococcus aureus, tuberculosis , Vibrio cholerae, Salmonella, bacteriophage and other cell membrane protein components, and make the protein spikes fall off, can no longer infect the bacteria.
