Hydrogen peroxide - urea is a solid composed of equal amounts of hydrogen peroxide and urea. This compound is a white crystalline solid, which dissolves in water to give free hydrogen peroxide. Often called carbamide peroxide in the dental applications, it is used as a source of hydrogen peroxide for bleaching, disinfection, and oxidation.
