This property makes it an extremely effective disinfectant that can quickly destroy the cell walls, cell membranes, and internal protein and nucleic acid structures of bacteria, viruses, and other microorganisms, thereby achieving the purpose of sterilization and disinfection. In the medical and health field, hypochlorous acid is widely used for hospital environment disinfection, medical instrument disinfection, and wound care. Its mild and efficient disinfection characteristics can effectively kill pathogens and reduce irritation to human tissues, which is helpful for wound healing. In the food industry, hypochlorous acid can be used for cleaning and disinfection of food processing equipment and sterilization of food raw materials, which can effectively inhibit microbial growth, prolong the shelf life of food, and ensure food safety.
