Sodium Perborate Tetrahydrate (CAS 10486-00-7) is a stable inorganic peroxide supplied as a white crystalline powder, and it serves as a reliable source of active oxygen for detergent bleaching, textile whitening, and dental care formulations. This Technical Grade crystalline solid is a cornerstone of the modern laundry detergent industry for its mild yet effective bleaching.

In the textile sector, it serves as a powerful oxidizing agent for dye fixation and fabric whitening. Its controlled release of oxygen ensures that delicate cotton and wool fibers are not damaged during high-speed processing.

As a disinfectant, it is utilized in institutional cleaning and oral care formulations for its antimicrobial properties. It remains stable in dry powder blends, only activating upon contact with water at elevated temperatures.
