Food Grade Hydrogen Peroxide for Food Grade Stabilizers
Bill (San Fernando, Philippines) on 03/02/2010:
Well here's something interesting that I've just found. I use HP quite alot, looks like the FDA are trying to squeeze out HP for internal use completely. Probably part of their Codex Alimentarius tactics. It seems that perhaps even food grade HP may not even be so safe from additives. Here are some extracts:
"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 after the additives added by the manufacturer for compliance. If the packager pours food grade H2O2 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."
"Hydrogen Peroxide Grades
3% Hydrogen Peroxide (Drug/Grocery Store Variety)
Used as antimicrobial agent for treating wounds and sanitizing agent
[Made from 50% Super D Peroxide, Diluted. Contains stabilizers - phenol, acetanilide, sodium stanate, tetrasodium phosphate among them.]
[This peroxide contains known chemicals do not ingest!]
6% Hydrogen Peroxide
Used by Beauticians for Coloring Hair. Used as sanitizing agent.
Comes in strengths labeled 10,20,40 volume. Must have activator added to be used as a bleach.
[Contains stabilizers, additives, and impurities dependent on manufacturing and dilution process. Do not ingest.]
30% Re-Agent Hydrogen Peroxide
Used in medical research.
[Contains stabilizers, additives, and impurities dependent on manufacturing and dilution process. Do not ingest.]
30-32% Electronic Grade Hydrogen Peroxide
Used for washing transistors and integrated chip parts before assembly.
[Contains stabilizers, additives, and impurities dependent on manufacturing and dilution process. Do not ingest.]
35% Food Grade Hydrogen Peroxide (Also 50% Food Grade H2O2)
[....*....]. Also used to spray inside of foil lined containers for food storage - known as the aseptic packaging system. [...*...additional information removed for FDA compliance]
[Contains stabilizers, additives, and impurities dependent on manufacturing and dilution process.
--e.g. This Food Grade Hyrogen Peroxide is Stabilized using tin based formulations ]
35% Technical Grade Hydrogen Peroxide
Used for waste water treatment and the disinfection of potable water, cosmetics, and laundry applications. [...*...additional information removed for FDA compliance] [May contain a small amount of phosphorus to neutralize any chlorine in the water it is combined with.]
MATERIAL SAFETY DATA SHEET & Technical Details: Hydrogen Peroxide (20 to 40%)
35% Standard Grade Hydrogen Peroxide (Also 50%, 60%, 70% Standard Grades)
Used mainly for bleaching in the pulp and paper industry and in the textile industry; oxidation reactions in the chemical industry; environmental processes (detoxification and deodorization). Used for Waste water treatment.
[Contains stabilizers, additives, and impurities Do not ingest.]
90% Hydrogen Peroxide
Used by the military as a source of Oxygen at Cape Canaveral. Used as a propulsion source in rocket fuel.
99.6% Hydrogen Peroxide
This was first made in 1954 as an experiment to see how pure a hydrogen peroxide could be manufactured. "
It seems that even food grade HP will have stannous or tin stabilizers in it at a minimum. This won't stop me using HP though, since I only use drops anyway, but the article is interesting.
