Its potent antimicrobial properties enable it to effectively eliminate a wide variety of harmful microorganisms. It is frequently used as a water treatment agent to purify drinking water and disinfect swimming pools.
Hypochlorous acid is widely used for disinfection in a variety of industries. When white blood cells detect pathogens such as bacteria or viruses, they release HOCl to neutralize and destroy them. Our immune system naturally produces it as part of the body’s defense mechanism against infections. It also does not leave any harmful residues, making it suitable for use in healthcare, food processing, and household cleaning.īecause of its ability to kill bacteria, viruses, and other microorganisms, HOCl is an important oxidizing agent and disinfectant. When used in appropriate concentrations, it is considered safe for use around humans, animals, and plants. Hypochlorous acid has gained popularity in recent years as a safe and environmentally friendly alternative to traditional chemical disinfectants. Technological advancements have reduced manufacturing costs and enabled the production and bottling of hypochlorous acid water for residential and commercial use. Despite its superior disinfectant properties, it is less commonly used as a disinfectant than bleach and alcohol due to its higher cost. The active compounds quickly deteriorate back into salt water in solution, losing their disinfecting capability and making it difficult to transport for widespread use. Such solutions, in low concentrations, can be used to disinfect open wounds.ĭespite being discovered a long time ago, the stability of hypochlorous acid water for disinfection is difficult to maintain. Hypochlorous acid solutions, like many other disinfectants, will kill pathogens absorbed on surfaces, such as COVID-19. HOCl is produced in living organisms by the reaction of hydrogen peroxide with chloride ions catalyzed by the heme enzyme myeloperoxidase (MPO). Hypochlorous acid is also found in the white blood cells of mammals, including humans, as a defense against foreign bodies. The related compounds sodium hypochlorite (NaClO) and calcium hypochlorite (Ca(ClO)2) are used in many commercial bleaches, deodorants, and disinfectants due to their strong antimicrobial properties. Because of its rapid equilibration with its precursor, chlorine, HClO cannot be isolated from these solutions. It is also known as chlorine oxide or chloric(I) acid. HClO and ClO are oxidizers and the primary disinfectants in chlorine solutions. Hypochlorous acid (ClOH, HClO, HOCl, or ClHO) is a weak acid formed when chlorine dissolves in water and partially dissociates to form hypochlorite, ClO.
