Sombody mentioned aaa-chemicals.com, but they have only the 90% Food-Grade (according to their internet-page).
What's about the electrolyte becoming hazardous (Cr6)? Is this happening no matter if I use Potassium Hydroxide or something else?
Hexavalent Chromium is created during the electrolysis process of Chrome plating. It can also be leached back out during the electrolysis process of generating HHO if you are using stainless steel as your electrodes. So to answer your question; it doesn't matter what electrolyte you use. It is the process of using stainless steel and electricity that creates the Cr(VI). Please make sure you dispose of your old electrolyte at your local hazardous waste disposal, and not down the drain.
As a side note, Hexavalent Chromium is also created when welding stainless steel, so make sure you have plenty of ventilation.
