  • Applications

    Hypochlorous acid (CAS 7790-92-3) is widely used as a fast-acting antimicrobial disinfectant and sanitizer across multiple industries. In household and consumer cleaning, it appears in surface cleaners and sanitizing sprays for kitchens and bathrooms. In the food and beverage sector, HOCl is employed for sanitation of equipment and utensils, as well as process-water treatment, due to its efficacy against a broad range of microbes while minimizing residue. In water treatment and cooling-water systems, it serves as a biocide to control microbial growth. In agriculture and horticulture, HOCl solutions are used for post-harvest produce washing and equipment disinfection. In electronics manufacturing and coatings/inks production, HOCl-based cleaners provide surface decontamination prior to assembly or finishing steps. In personal care and pharmaceutical contexts, HOCl may be formulated for mild cleaning and sanitizing applications, subject to formulation limits and regulatory requirements.
