Don't use bleach when you can easily make hypochlorous acid. Hypochlorous acid is bleach but acidified and much safer to the human body than bleach. Bleach is thousands of times more toxic to humans at the same HOCl concentration. You suggest using an OCl- concentration of 2500 ppm which would be extremely high for an equivalent therapeutic use of hypochlorous acid. You can easily use a 10 times lower concentration of hypochlorous acid for the same purpose, and it would still be total overkill. You can easily make hypochlorous acid with electrolysis safely or by mixing highly dilute bleach with highly dilute acid (vinegar) with a target pH range of 4-6. If your solution pH falls below about 4 there may be chlorine gas evolution which is generally undesirable. Above pH 4 it is not significant. Given the desired HOCl dilution hardly any chlorine gas will be emitted even if working in a confined space and using an excessively low pH. I recommend the electrolysis route for use in and around the body because the route is generally free from potentially harmful contaminants which may be in your bleach products. The bleach and acid method is useful to make a general purpose deodorant and disinfectant or if you trust your bleach to be free from harmful contaminants. https://www.dstec.com.my/wp-content/uploads/2020/04/pH-for-H...

Hypochlorous acid is hundreds of times more effective than bleach as a biocide because it is uncharged and can far more readily diffuse past the lipid bilayer of microbes to wreak havoc. Somehow, humans are generally much more immune to these effects. Whereas 0.1 ppm HOCl can kill most bacteria it takes approximately 10,000 ppm to damage most human cells. It is not recommended to use much over a handful of ppm in the nose and eyes.
