Hydrogen peroxide



Hydrogen peroxide (H2O2), unstable chemical compound that acts as an oxidizing agent that may cause poisoning. Hydrogen peroxide is marketed as an aqueous solution ranging from the common concentration of 3% as a topical antiseptic, 6% in hair preparations (bleaches, neutralizers, and so forth), to 30% for industrial and laboratory use and 90% for use in rocket propulsion. Decomposition of hydrogen peroxide may release large volumes of oxygen (10 times the volume for a 3% solution). Dropping a 3% solution on the eye, 3–5 times a day has been reported to be innocuous, but high-concentration hydrogen peroxide is generally feared as a cause of severe corneal damage. Ingestion of the commonly available household products (3–6%) should cause no problem other than possible mucous membrane and gastrointestinal irritation, while higher concentrations (such as 30%) are considered corrosive.
