High Quality Content by WIKIPEDIA articles! Sodium perborate (PBS) is a white, odorless, water-soluble chemical compound with chemical formula NaBO3. It crystallizes as the monohydrate, NaBO3·H2O, tetrahydrate, NaBO3·4H2O and trihydrate, NaBO3·3H2O. The monohydrate and tetrahydrate are the commercially important forms.Sodium perborate is manufactured by reaction of disodium tetraborate pentahydrate, hydrogen peroxide, and sodium hydroxide.The monohydrate form dissolves better than the tetrahydrate and has higher heat stability; it is prepared by heating the tetrahydrate. Sodium perborate undergoes hydrolysis in contact with water, producing hydrogen peroxide and borate.
