Sodium percarbonate

Sodium percarbonate (CAS 15630-89-4), also known by the abbreviation SPC, is an adduct of sodium carbonate and hydrogen peroxide that releases active oxygen upon dissolution in water. It functions as a solid, free-flowing oxygen bleach and oxidizing agent across cleaning, textile, and water treatment applications. In laundry and household cleaning formulations, SPC delivers bleaching performance.

It serves as a direct alternative to liquid hydrogen peroxide, with the handling advantage of a dry solid. Textile processors use it to bleach natural fibers such as cotton and linen without fiber degradation. This avoids the issues associated with chlorine-based systems. Water treatment operations apply it as a biocide and oxidant to control biofilm, algae, and organic contaminants in municipal and industrial systems.

In personal care, it is incorporated into tooth-whitening powders and effervescent bath products where controlled oxygen release is the functional mechanism. It is supplied as a white, free-flowing granular powder. The product typically features an active oxygen content of around 13–14% or expressed as 30% equivalent hydrogen peroxide. Standard commercial grades include technical and detergent grades for various uses.

Coated variants are available to improve storage stability and moisture resistance in finished formulations. Bulk supply is available in bags and big bags for large-scale industrial manufacturing requirements. Food-contact and high-purity grades are offered for regulated applications. Our material meets rigorous industry specifications to ensure consistent performance and safety across all global supply chains.
