Sodium percarbonate, also known as oxygen bleach, is a white, granular or powdered solid oxidizer. It is an additional salt of hydrogen peroxide and sodium carbonate that provides a solid source of hydrogen peroxide. When dissolved in water, sodium percarbonate liberates hydrogen peroxide. Sodium percarbonate is used primarily as a bleaching agent in cleaning products.
Disclaimer: Exposure to sodium percarbonate can cause irritation to the skin, eyes, and respiratory tract. Ingestion should be avoided at all concentrations. Store at a cool room temperature.
