hydrogen peroxide, (H₂O₂), a colourless liquid usually produced as aqueous solutions of various strengths, used principally for bleaching cotton and other textiles and wood pulp, in the manufacture of other chemicals, as a rocket propellant, and for cosmetic and medicinal purposes. Solutions containing more than about 8 percent hydrogen peroxide are corrosive to the skin.

First recognized as a chemical compound in 1818, hydrogen peroxide is the simplest member of the class of peroxides. Of the several processes of manufacture, the principal ones involve reactions of oxygen from the air with certain organic compounds, especially anthraquinone or isopropyl alcohol. Major commercial grades are aqueous solutions containing 35, 50, 70, or 90 percent hydrogen peroxide and small amounts of stabilizers (often tin salts and phosphates) to suppress decomposition.

Hydrogen peroxide decomposes into water and oxygen upon heating or in the presence of numerous substances, particularly salts of such metals as iron, copper, manganese, nickel, or chromium. It combines with many compounds to form crystalline solids useful as mild oxidizing agents; the best-known of these is sodium perborate (NaBO₂·H₂O₂·3H₂O or NaBO₃·4H₂O), used in laundry detergents and chlorine-free bleach products. With certain organic compounds, hydrogen peroxide reacts to form hydroperoxides or peroxides, several of which are used to initiate polymerization reactions. In most of its reactions, hydrogen peroxide oxidizes other substances, although it is itself oxidized by a few compounds, such as potassium permanganate.

Pure hydrogen peroxide freezes at −0.43 °C (+31.3 °F) and boils at 150.2 °C (302 °F); it is denser than water and is soluble in it in all proportions.

Dr. Madsen: Well, I think in our minds it makes sense that we worry about germs and we have a wound, and then the germs get in through that wound, so we've got to get rid of all the germs. But over time and with experience, we've come to see that pouring that in there and just scrubbing that thing out a lot more with that than is necessary is really damaging the healthy tissue, number one. And then we've also done studies looking at very simple things we can do to clean wounds that work just great, and we don't have to use the hydrogen peroxide.
