Physical description & handling notes

• Anhydrous sodium peroxoborate consists of white to yellowish free-flowing crystals. It is hygroscopic and forms a partial hydrate in damp air. It is noncombustible but mixtures of organic material are readily ignited and may burn fiercely.
• White hygroscopic solid; Produces oxygen gas when dissolved in water; [Hawley] White to yellowish hygroscopic solid; [CAMEO] White odorless crystalline granules; [MSDSonline]
• White, amorphous powder
• Stable as powder
• Stable when kept cool and dry, but decomposes with the liberation of oxygen in warm or moist air.
• When heated to decomposition, it emits toxic fumes of /disodium oxide/.
