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.

30-32% 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.
