The leading merchandise of this h2o are hypochlorous acid (e.g., in a focus of about a hundred and forty four mg/L) and chlorine. As with all germicide, the antimicrobial exercise of superoxidized h2o is strongly afflicted by the concentration in the active ingredient (accessible free of charge chlorine) 536. A single producer generates the disinfectant at The purpose of use by passing a saline solution above coated titanium electrodes at 9 amps. The merchandise produced has a pH of five.0–six.five and an oxidation-reduction prospective (redox) of >950 mV. While superoxidized drinking water is intended for being created fresh new at the point of use, when tested under clean circumstances the disinfectant was efficient within 5 minutes when forty eight several hours previous 537.
