UREA PEROXIDE.

Questionable CAS 124-43-6 / OXIDISING

Urea Peroxide, also known as carbamide peroxide, is a stable compound of hydrogen peroxide and urea. It slowly decomposes to release these components, acting primarily as an oxidizing and bleaching agent.

oxidizing antiseptic bleaching keratolytic

Science

Upon contact with water or organic matter, it liberates hydrogen peroxide, which generates reactive oxygen species for potent oxidation and antiseptic action. The urea component adds stability and a mild keratolytic effect, aiding substance penetration.

Our Assessment

Questionable

Due to significant irritancy risks, strict concentration limits for dermal use, and primary applications outside of traditional precision skincare, its utility in Moumoujus products is limited and requires careful consideration.
