As an oxidizing agent, a bleaching agent, deodorant, pharmaceuticals and dyes, and as an analytical reagent.Sodium peroxide acts as a bleaching agent in laundry and wood pulp. It finds application in the extraction of minerals from various ores. It acts as an oxidizing agent as well as an oxygen source by reacting with carbon dioxide. Furthermore, it is used as a deodorant and an analytical reagent. It is also useful in scuba gear and in submarines.


Air sensitive and hygroscopic. Keep the container tightly closed in a dry and well-ventilated place. It reacts with water violently to give sodium hydroxide and hydrogen peroxide. Incompatible with strong reducing agents, organic materials, alcohols and powdered metals.
