What is Sodium perborate?

Sodium perborate (CAS 7632-04-4), also known as sodium peroxometaborate, is an oxidizing salt that releases active oxygen upon dissolution in water.

Detergent and laundry: oxygen bleach that removes stains and whitens fabrics without the fiber damage associated with chlorine-based alternatives
Pulp and paper: bleaching cellulose fibers while maintaining fiber integrity
Personal care: tooth-whitening products and denture cleansers
Hair bleaching: controlled peroxide delivery
Water treatment and textile processing: biocide and oxidative cleaning agent for effluent treatment
It serves as a cleaning booster across multiple industrial sectors.

Monohydrate and tetrahydrate forms
Monohydrate: lower moisture content and higher active oxygen content
Particle size and active oxygen content are key quality parameters buyers specify

Melting Point 60°C

Appearance Colourless, prismatic crystals or white or almost white powder, stable in the crystalline form.
