Carbamide peroxide

Carbamide peroxide (CAS 124-43-6), also known as urea peroxide and designated E927b, is a stable solid oxidant that releases active oxygen upon contact with water. This controlled release makes it a practical alternative to liquid hydrogen peroxide in bleaching, whitening, and antimicrobial applications across multiple industries and manufacturing sectors.

In personal care and cosmetics, it is the active ingredient in tooth whitening gels, ear drops, and hair bleach formulations, where its solid form allows precise dosing and extended shelf life. Textile and paper processors use it as a bleaching agent for fibers and pulp, particularly where dry or low-moisture processing conditions are preferred for efficiency and safety.

In water treatment, it functions as an oxidizing biocide for disinfection and odor control in both industrial and municipal systems, providing a stable source of active oxygen for purification. Pharmaceutical manufacturers incorporate it into topical antiseptic preparations and oral care products, sourcing it to USP or BP specifications to ensure the highest levels of purity.

The material is supplied as a white crystalline powder, typically at 35% active oxygen content by weight. Standard commercial grades include pharmaceutical and food-grade specifications to meet requirements. Technical grade is also available for industrial bleaching and water treatment applications. This versatile oxidant remains a staple for companies requiring stable, high-performance bleaching agents.
