⚗️ Chemical Overview

Urea hydrogen peroxide appears as a solid or paste-like semisolid. Used to make plastics. Urea hydrogen peroxide is a mixture obtained by combining equimolar amounts of hydrogen peroxide and urea. It has a role as a reagent, a disinfectant and an oxidising agent. It contains a urea and a hydrogen peroxide. Carbamide peroxide, also known as urea-hydrogen peroxide, is a water-soluble, white crystalline solid compound consisting of hydrogen peroxide and urea. As it is a source of hydrogen peroxide, it can be found in disinfecting and dental bleaching products. Some adverse effects of carbamide peroxide as a dental bleaching agent include dentin sensitivity and/or gingival irritation led by unstable and reactive H+ free radicals and low pH from prolonged use. It may also alter enamel surface morphology via enamel mineral loss and surface roughening. The FDA considers carbamide peroxide to be safe in oral mucosal injury drug products as an oral wound healing agent, although there is insufficient data to establish general recognition of the effectiveness of this ingredient as an oral wound healing agent. It is available in OTC otic drugs as non-water, non-oil-based solutions used to soften, loosen and remove excessive ear wax, or cerumen.
