It refers to a disinfectant which is soluble in water to produce hypochlorite with microbicidal activity, and its microbicidal active ingredient is often represented by effective chlorine. The hypochlorous acid has a small molecular weight and easily diffuses to the surface of the bacteria and penetrates the cell membrane into the bacteria, causing the bacterial protein to oxidize and causing the bacteria to die. Chlorine disinfectants kill a variety of microorganisms, including bacterial propagules, viruses, fungi, Mycobacterium tuberculosis, and the most resistant bacterial spores. Such disinfectants include inorganic chlorine compounds (such as sodium hypochlorite, calcium hypochlorite, trisodium phosphate), organochlorine compounds (such as sodium dichloroisocyanurate, trichloroisocyanuric acid, ammonium chloride T, etc.). Inorganic chlorine is unstable in nature, susceptible to light, heat and moisture, and loses its active ingredients. Organochlorine is relatively stable, but it is unstable after being dissolved in water.
