The EPA C.diff list is not that long (around 65 products), and the only other product on the list that looks to be HOCl is Annihilyte, which up until recently was a sub-registered product made by PCT machines. They now have their own number, but the machines I expect are the same/similar considering the people involved with that company.
Though PCT's product is listed on the EPA's C-Diff list, (at a minimum of 500ppm) what perplexes me is why Pathisol would reference what the (US) EPA says, correctly or otherwise.
