Description
Sodium perborate monohydrate (CAS 10332-33-9) is an inorganic oxidising salt commercially known under trade names including Perasafe, Interox A, and Clinsodent. It releases active oxygen upon dissolution in water, making it the functional basis for oxygen-based bleaching and disinfection systems. No E-code designation applies to this substance.
In textile and paper processing, it oxidises chromophores in fibres and pulp at temperatures above 60°C, achieving whitening without chlorine chemistry. Personal care formulators use it as the active component in denture cleaners and tooth-whitening products, where controlled peroxide release breaks down stain compounds. Water treatment applications exploit its biocidal action against bacteria and algae.
The material is supplied as a white crystalline powder compliant with REACH registration requirements. Procurement teams should confirm grade specifications against relevant pharmacopoeial or industrial standards depending on end-use. Standard packaging formats for European B2B supply typically include 25 kg bags, with HS code 28403000 applicable for import and export classification.
