Grades Of Hydrogen Peroxide
3% Hydrogen Peroxide (Drug/Grocery
Store Variety)
Made from 50% Super D Peroxide, Diluted. Contains
stabilizers - phenol, acetanilide, sodium stanate,
tetrasodium phosphate among them.
6% Hydrogen Peroxide (Used by Beauticians for Coloring
Hair)
Comes in strengths labeled 10,20,40 volume. Must have
activator added to be used as a bleach. Stabilizers used
unknown at this point.
30% Re-Agent Hydrogen Peroxide
Used in medical research. Also contains stabilizers.
30-32% Electronic Grade Hydrogen Peroxide
Used for washing transistors and integrated chip parts
before assembly. Stabilizers unknown at this point.
35% Technical Grade Hydrogen Peroxide
Contains a small amount of phosphorus to neutralize any
chlorine in the water it is combined with.
35% Food Grade Hydrogen Peroxide
(Also 50% Food Grade Hydrogen Peroxide)
Used in food products like cheese, eggs, whey products.
Also used to spray inside of foil lined containers for
food storage - known as the aseptic packaging system.
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 hydrogen peroxide could be.
Methods of Producing Hydrogen Peroxide
1. Chemically - treat Barium Peroxide with Sulfuric Acid.
Barium Sulfate settles to the bottom and Hydrogen
Peroxide is drained off. (To concentrate, it is vacuum
distilled.)
2. Treat water with ultraviolet light.
3. Electricity - silent, or open spark methods.
4. Bubble Ozone (03) through cold water.
