What concentration of hypochlorous acid should be used?


The concentration that should be used depends on the application. Sanitizing food such as fruits & vegetables and fish & seafood is highly effective at 20-30 ppm however the FDA allows concentrations to be used as high as 60 ppm without requiring a post rinse. Sanitizing food contact surfaces is also effective at 20-30 ppm however concentrations as high as 200 ppm are allowed by the FDA. Water disinfection is effective at 1-2 ppm however the EPA allows up to 4 ppm. When deciding what concentration to use, it is best to refer to the research. Over 300 research articles have been published covering nearly every application. Click here to visit the research database organized by industry.
