Carbamide peroxide (CAS 124-43-6) is a solid 1:1 addition compound of urea and hydrogen peroxide that releases hydrogen peroxide on dissolution. It is used as a controlled oxidizing and bleaching agent – including hair bleaching and oxidation of permanent-wave systems – and in plastics manufacture, blueprint development, and starch modification.
Frequently Asked Questions
What is urea peroxide used for?
Urea peroxide (carbamide peroxide, CAS 124-43-6) is a solid 1:1 addition compound of urea and hydrogen peroxide that releases hydrogen peroxide on dissolution. It is used as a controlled, dry source of hydrogen peroxide for oxidizing and bleaching, including hair bleaching and permanent-wave oxidation, and in plastics manufacture, blueprint development, and starch modification.
Is urea peroxide the same as hydrogen peroxide?
No. Urea peroxide is a stable solid adduct of urea and hydrogen peroxide (CH6N2O3) that releases hydrogen peroxide when dissolved. It provides a dry, metered way to deliver hydrogen peroxide, which is otherwise an aqueous liquid; the two are distinct materials with different handling and specifications.
What does USP mean on urea peroxide?
USP indicates the material is tested and labeled to the United States Pharmacopeia compendial standard for the substance. Confirm the applicable monograph and assay against the lot CoA when ordering.
How is urea peroxide shipped and supplied in bulk?
Urea peroxide is a solid oxidizer typically supplied as crystals, powder, or granules in drums or bags. It is classified for transport under UN 1511 (Urea hydrogen peroxide). Review the SDS for the as-shipped grade and observe oxidizer handling before specifying packaging.
What is the CAS number and HS code for urea peroxide?
The CAS number is 124-43-6 and the formula is CH6N2O3. It is generally classified under HS 2847.00 (hydrogen peroxide, whether or not solidified with urea); confirm the final classification with your customs broker.
