Abstract: A stabilised hypochlorous solution is disclosed. The solution includes hypochlorous acid (HOCl), hypochlorite (ClO—), and chlorine (Cl—) that combine to provide a total chlorine concentration. The total chlorine concentration is at or below 300 ppm, the hypochlorous acid, measured by UV spectroscopy at 230 nm, is the predominant species, the hypochlorite, measured by UV spectroscopy at 290 nm, is present at significantly lower levels than that of the hypochlorous acid, such that a ratio of hypochlorous acid to hypochlorite is greater than 7.5:1. The solution has a pH of between about 7 and 4 and a shelf life of at least 12 months, at 22° C., such that the amount of hypochlorous present remains at above 80% of its starting concentration, and the pH remains above 4.
