Re: OT / Food grade and Technical grade hydrogen peroxide

Food grade and Technical grade hydrogen peroxide are essentially the same. However, the FDA regulates among other things the processing of Food grade hydrogen peroxide.

For Example:
The manufacturer produces 10 drums of technical grade H2O2. He would test the first and the last drum for quality and purity. The FDA inspects or test all 10 drums. All 10 drums are now considered to be food grade H2O2 (Hydrogen-Peroxid) after the additives added by the manufacturer for compliance. If the packager pours food grade H2O2 (Hydrogen-Peroxid) out of one of those drums into a smaller container, it is no longer a "food grade" unless that smaller container is also tested for the FDA compliance.
