What is hydrogen peroxide?

Hydrogen peroxide is a chemical compound with the formula H2O2. The aqueous solution is called hydrogen peroxide. It is colorless and slightly more viscous than water.

Hydrogen peroxide has both oxidizing properties, for example with regard to iodide ions, and reducing properties, for example with regard to permangana ions. It is an effective bleach. It is used as an antiseptic.

Hydrogen peroxide occurs naturally in living things as a byproduct of cellular respiration. All aerobic organisms have enzymes, apple peroxidases, which catalyze the dismutation of H2O2 into H2O and O2.

The concentration of hydrogen peroxide solutions is usually given in "volumes" or mol/l. By definition, 1 liter of hydrogen peroxide at x volumes is likely to release x liters of O2 gas, measured under normal conditions of temperature and pressure, by disproportioning H2O2. The recommended correspondence is 10 parts for 1 mol/l.

What is hydrogen peroxide used for?

-Industrial use

• Hydrogen peroxide is mainly used to bleach paper pulp (about two-thirds of the volume produced worldwide). Bleached pulp can be chemical, mechanical or recycled.
• In highly purified form, it is of crucial importance in the electronics industry (chip manufacturing requires flawless disinfection) and the volumes produced for this are constantly increasing.
• It is used in the environmental field for the treatment of water, soil and gases (sulphurisation, deNox, etc.).
• It is in certain solutions that are intended to purify pool or spa water and destroy green algae.
• At high temperature, it is used to sterilize composite food packaging just before the contents are incorporated into them.
• The oxidation of luminol dissolved in sodium hydroxide produces, without dye, an intense blue light without heat output. This is the basic reaction of chemiluminescence, for example, used in light bars.
• It is a promising oxidant for the synthesis of various chemicals.

-Medical or aesthetic use

• Naturally secreted by the human body, it inhibits the synthesis of colored pigments, including melanin, and is responsible for bleaching hair. It can be used (in low concentration, from 2% to 12%) to bleach hair and hair, hence the expression "peroxide blonde". It is used in the hairdressing industry as a fixative to complete a permanent or to produce oxidation staining.
• Disinfectant for local treatment. Cleaning wounds with hydrogen peroxide should be done quickly, as it damages the new cells. However, it is known to be effective against tetanus, whose bacteria is essentially anaerobic and contraindicated to aerobic bacteria.
• The World Health Organization (WHO) has proposed hand-held antiseptic solutions in which the antimicrobial effect of highly concentrated alcohol (ethanol or isopropanol) is enhanced by a low concentration of hydrogen peroxide, while the third component, glycerol, acts as a humectant. These formulations can be prepared locally in remote locations where commercial hand sanitizers are not readily available. For these regions, the local synthesis of diluted hydrogen peroxide is of immense importance.
• Combined with urea in the form of carbamide peroxide H2O2 CO(NH2)2, hydrogen peroxide serves as a tooth whitening agent.
• It is part of the composition of certain treatments in dermatology, especially in seborrheic keratosis

-Other applications

• Hydrogen peroxide has been used as a hemoglobin indicator in forensic science for several years. Nowadays, this test is no longer used in forensic medicine because more precise techniques exist. This discovery was made by the German chemist Christian Schönbein (1799-1868).
• Hydrogen peroxide is used to react luminol using iron (II) from hemoglobin as a catalyst.
• It is also a disinfectant for hydroponics and root oxygenation.
• In combination with hydroquinone, hydrogen peroxide is used by the so-called "bombardier" beetle to create an explosive solution at high temperature (100°C). The solution is then projected onto its predators as a defense system.
• It is part of the very spectacular oscillating reactions of Briggs-Rauscher and Bray-Liebhafsky.
