A stable antimicrobial aqueous hypochlorous acid solution

摘要: A stable antimicrobial aqueous hypochlorous acid solution that retains its activity for at least three months and can be provided with high levels of (more than 500ppm), the composition having low chloride concentrations (maximum 1:3 to hydrochlorous acid) a pH between 3.5 7.0, preferably 5.5 6.5, stabilise without need additional stabilisers. Also claimed is process preparation an comprising steps adding chlorine calcium hydroxide provide hypochlorite, water, removing in solid dissolving hypochlorite water alkaline hupochlorite ions, precipitating as enable subsequent removal, adjusting resultant ions around 5-6 precipitate any remaining removal 7.
