Other major industrial applications for hydrogen peroxide include the manufacture of sodium percarbonate and sodium perborate, used as mild bleaches in laundry detergents. Other bleaching applications are becoming more important as hydrogen peroxide is seen as an environmentally-benign alternative to chlorine-based bleaches. Modern manufacture methods are discussed below.Ībout 50% of the world's production of hydrogen peroxide in 1994 was used for pulp- and paper-bleaching. Thenard's process was used from the end of the 19th century until the middle of the 20th century. An improved version of this process used hydrochloric acid, followed by sulfuric acid to precipitate the barium chloride byproduct. Hydrogen peroxide was first isolated in 1818 by Louis Jacques Thénard by reacting barium peroxide with nitric acid.
It has strong oxidizing properties and is therefore a powerful bleaching agent that has 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. Hydrogen peroxide (H 2O 2) is a very pale blue liquid which appears colourless in a dilute solution, slightly more viscous than water. Materials in their standard state (at 25☌, 100 kPa)

CHEMICAL FORMULA FOR HYDROGEN PEROXIDE SKIN
Hydrogen peroxide doesn't have any smell, and it is not absorbed by the skin but can cause poisoning when ingested or inhaled. Hydrogen peroxide is inflammable but also a powerful oxidizing agent that can cause a fire instantly when organic material comes in contact. Hydrogen peroxide is much more affected as a bleaching agent and a disinfectant.Ĭoncentrated hydrogen peroxide is used as a propellant in a rocket due to its reactive property. Hydrogen peroxide use in industry as a concentrated form (greater than 30%). Hydrogen peroxide is mainly used as an aqueous solution, and it is also available in a diluted form (3% to 10%) for household use.
Pure hydrogen peroxide is a colorless liquid & has a bitter taste, and it is a crystalline solid below 12☏. It is a colorless, clear, and non-flammable chemical. Hydrogen peroxide(h2o2) is the basic type of peroxide available.
