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.

Where is Sodium percarbonate used?

• Cleaning: solid, free-flowing oxygen bleach and oxidizing agent
• Laundry and household cleaning: bleaching performance
• Textile processing: bleaches natural fibers such as cotton and linen without fiber degradation
• Water treatment: biocide and oxidant controlling biofilm, algae, and organic contaminants in municipal and industrial systems
• Personal care: tooth-whitening powders and effervescent bath products where controlled oxygen release is the functional mechanism
• It serves as a direct alternative to liquid hydrogen peroxide, with the handling advantage of a dry solid.
• Eliminates odours and organic residues in drains and water systems.
• Cleans tanks, utensils and surfaces in food industries.

Good to know: This avoids the issues associated with chlorine-based systems.

Formulation notes

• Reacts with metals and their salts, organic acids, and reducing agents.
• Do not use in aluminum pipes.
• The coating is added to improve stability and durability compared to uncoated sodium percarbonate.

Typical specification

• Supplied grade contains 12.5-13.5% active oxygen.
• Solubility in water is 14 g/100 mL at 20°C.
• Coated sodium percarbonate is a white, crystalline, water-soluble solid.
• The coating is typically a combination of organic and inorganic materials.
• Average particle size is in the 600-900 μm range.

Regulatory status

• For transport, classified under UN hazard class 5.1 with UN packing group III.
• Causes serious eye irritation under UN GHS criteria.

Storage, packaging and handling

• If temperature exceeds 50°C, self-accelerating decomposition may occur, releasing heat, oxygen, and vapor.
• Store in a cool and dry environment.
• Store separately from water, alkalis, heavy metal salts, reducing agents and organic substances in a cool, ventilated, closed warehouse at ≤35°C.
