Sodium percarbonate is a chemical, an adduct of sodium carbonate and hydrogen peroxide (a perhydrate), with formula 2Na2CO3 · 3H2O2. It is a colorless, crystalline, hygroscopic and water-soluble solid. It is used in some eco-friendly cleaning products and as a laboratory source of anhydrous hydrogen peroxide.

This product contains the carbonate anion, and should not be confused with sodium peroxocarbonate Na2CO4 or peroxodicarbonate Na2C2O6, which contain different anions.

Uses:As an oxidizing agent, sodium percarbonate is an ingredient in a number of home and laundry cleaning products, including bleach products such as OxiClean, Tide laundry detergent, and Vanish. It contains no phosphorus or nitrogen. Dissolved in water, it yields a mixture of hydrogen peroxide (which eventually decomposes to water and oxygen) and sodium carbonate ("soda ash").

Sodium percarbonate can be used in organic synthesis as a convenient source of anhydrous H2O2, in particular in solvents that cannot dissolve the carbonate but can leach the H2O2 out of it.
