Hydrogen Peroxide

liquid compound of hydrogen and oxygen (used as an antiseptic, to bleach hair, etc.)

Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution, slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper, but has also found use as a disinfectant, as an oxidizer, and in rocketry (particularly in high concentrations as high-test peroxide (HTP) as a monopropellant), and in bipropellant systems.

(synonym) peroxide
(hypernym) oxide

chemical formula H2O2, hydrogen peroxide is an oxidizer used primarily as part of sulfuric acid peroxide, and SC1 cleans. hydrogen peroxide is commonly sold as a 30% solution and has a density of 1.10Kg/L. Hydrogen peroxide will burn eyes or skin on contact and may react strongly with other chemicals.
