Electrolyzed water (EW) is a cost-effective, eco-friendly disinfectant with strong antimicrobial and antibiofilm properties. Produced by electrolysis of salt and water, it generates hypochlorous acid (HOCl), which rapidly kills pathogens by damaging cell structures. Findings show significant effectiveness in wound care, hand hygiene, oral health, and surface disinfection, with fast microbial reduction and minimal toxicity. EW demonstrates strong practical potential for safer infection control in clinical and healthcare environments, although short shelf life of EW and reduced efficacy in organic matter can be addressed.
