Chemical Properties

Different sources of media describe the Chemical Properties of 7632-04-4 differently. You can refer to the following data:
1. Sodium perborate, anhydrous, NaB03 is a white,amorphous powder of unknown constitution containing active oxygen that evolves oxygen gas when dissolved in water,and is hygroscopic. Derived by heating sodium perborate tetrahydrate. Used as a denture cleaner and oxygen source. Sodium perborate, monohydrate, NaB03·H20 , better represented as Na2(B2(02)2(OH)4) is a white, amorphous powder that is rapidly soluble in water givinga solution of H202 and sodium borated.Derived by partial dehydration of sodium perborate tetrahydrate. Used as a denture cleaner and bleaching agent.
2. Colourless, prismatic crystals or white or almost white powder, stable in the crystalline form.

Uses

Different sources of media describe the Uses of 7632-04-4 differently. You can refer to the following data:
1. Sodium perborate is the most widely used solid peroxygen compound. Commercially, it is available as a tetrahydrate and a monohydrate. The tetrahydrate is produced by treating a borax solution with hydrogen peroxide and sodium hydroxide.
2. Antiseptic.
