Carbamide Peroxide
Also called urea peroxide:


Carbamide peroxide, also called urea peroxide, is an oxidising agent, consisting of hydrogen peroxide compounded with urea. The molecular formula is CH6N2O3, or CH4N2O.H2O2. It is a white crystalline solid that releases oxygen in contact with water.

The chemical is a skin, eye and respiratory irritant. It is also corrosive and causes burns. It doesn't hurt at 10% concentration (3% hydrogen peroxide equivalent) but it might hurt at 35% (12% equivalent), causing white chemical burns on skin and gums alike.

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 to

1. whiten teeth
2. relieve minor inflammation of gums, oral mucosal surfaces and lips including canker sores and dental irritation[3]; and to
3. emulsify and disperse ear wax.

Carbamide peroxide is commonly encountered in cosmetic dentistry, where it is used to "bleach" teeth. The active ingredient is hydrogen peroxide, which acts to oxidise interprismatic extrinsic staining within tooth enamel. There are several methods of applying the peroxide gel to the tooth ranging from night-guard application at home or in-surgery application. The bleaching obtained is proportional to the length of time the peroxide is applied to the tooth, and the concentration used. The concentration most commonly used for tooth whitening purposes is 15% (that is available for over-the-counter sales in pharmacies). The higher concentrations of 22 and 35% for sale here on Superwhite Smile.Com is the same strength used by dentists charging HUNDREDS of dollars more!
