Hypochlorous acid (HOCl) solution (200 ppm, pH 6) was prepared and evaluated for their stabilities and microbicidal activities. We demonstrated that HOCl is unstable against ultraviolet (UV) light, sunshine, contact with air, and elevated temperature (≧25℃). Furthermore, in the HOCl solution, the presence of excess NH2- or CHO-containing organic compounds such as proteins and carbohydrates, or of inorganic ions such as NO2-, SO3-, PO3-, Fe2+, Cu2+, and CuS, resulted in the rapid consumption of HOCl by oxidation reactions, and significantly decreased the microbicidal activity of the HOCl solution against coliform bacteria and total viable cell count. Thus, production of stable HOCl solution requires formulation in pure water harboring concentrations as low as possible of various compounds and ions, as well as storage in dark and cool conditions (<10℃) to maintain the concentration of HOCl molecules and microbicidal activity.

@mameruri_moni ここのリンクから読めますhttps://t.co/H915KYf3CQ それとは別に文部科学省のページからこんな資料を見つけたのですが、製品によっては殺菌効果がほとんど見られないものもあるようです。(実験開始時の濃度25ppm、終了時に4ppmの製品など。メーカー名を明かして欲しい…) https://t.co/oht0QxetMc
