Carbamide peroxide is a combination of urea and hydrogen peroxide that is widely used at low concentrations (~10%) to whiten teeth. Upon contact with water, oxygen is released, providing the bleaching (oxidizing) power.

Application:Peroxide used with N-halosuccinimides in an efficient α-halogentation of carbonyl compounds. Used with methyltrioxorhenium (412910) in a mild oxidation of imines to nitrones Also used to oxidize iodoarenes to hypervalent iodine compounds

Carbamide peroxide, (CH4N2O·H2O2), is a chemical that contains hydrogen peroxide and urea – an organic compound. Pure carbamide peroxide has the form of white crystals or crystal powder, is soluble in water, and contains approximately 35% hydrogen peroxide. Carbamide peroxide is used as bleach or disinfectant in consumer products such as hair bleaches, hair perming products, hair relaxers, ear drops, antiseptic mouth washes, products to treat mouth sores, toothpastes, and tooth bleaching. It is also used in solutions for the disinfection of contact lenses and wounds.

Local:
Urea hydrogen peroxide is an unstable combination of urea and hydrogen peroxide in equal amounts. It is soluble in water, alcohol, and ethylene glycol. It decomposes at 75-85 C or by moisture. is used as a source of water-free hydrogen peroxide. It is used in the bleachings and deodorizing for fibers. It is used as a disinfectant in cosmetics, detergents and pharmaceuticals. Its applications include starch modification, color developer and catalyst of organic synthesis.

PRICE INFORMATION
Peroxide: Compound containing the peroxy group (-O-O-), chainlike structure, containing two oxygen atoms, each of which is bonded to the other and to a radical or some element. It is considered that hydrogen peroxide is the starting material to prepare organic and inorganic peroxides commercially. Hydrogen Peroxide H2O2, is a powerful oxidizing agent. The most valuable property of hydrogen peroxide is that it breaks down into water and oxygen and therefore does not form any persistent, toxic residual compounds. It is used in the processes of epoxidation, oxidation, hydroxylation and reduction. Its oxidizing properties are used in the bleachings and deodorizing for textile, hair and in paper manufacture. It is also used medicinally as an antiseptic.  Its application involves the production of chemicals like perhydrates as well as organic peroxides in which some organic (or inorganic) substituents have replaced one or both hydrogens. Some metals form peroxides in air sodium, barium or zinc. Metal peroxide releases oxygen slowly in contact with atmospheric moisture and used to as disinfectants in cosmetics, detergents, toothpaste and pharmaceuticals. They can be used in the bleachings and deodorizing and a oxygen release source in agricultural application to generate contaminated soils and lakes. Organic Peroxides are powerful oxidizing agents releasing oxygen. They are widely used as initiators,catalysts and crosslinking agent for the polymerization process in the plastics manufacturing industry and as chemical intermediates, bleaching agents, drying and cleaning agents. They are also used as antiseptics, disinfectants and germicides medically for cosmetics, detergents, toothpaste and pharmaceuticals. Organic peroxides include peroxyacetic acid, benzoyl peroxide, cumyl and tert-butyl peroxides.
