Sodium percarbonate is a white crystalline water-soluble chemical compound of sodium carbonate and hydrogen peroxide.[1]
It is an oxidizing agent and ingredient in a number of home and laundry cleaning products.[1] Despite the name, it is, in fact, a carbonate perhydrate.[1] Dissolved in water, it releases H2O2 and soda ash (sodium carbonate)[1]:
- 2Na2CO3·3H2O2 → 2 Na2CO3 + 3 H2O2
Sodium percarbonate is the active ingredient in many powdered oxygen bleach products.[2] The Per from perborate or percarbonate has given the name for several laundry detergent products like Persil.
