Sodium perborate tetrahydrate CAS:10486-00-7
Description:
Sodium perborate is a white, free-flowing crystalline compounds soluble in water. Sodium Perborate is a stable, solid source of active oxygen. Sodium perborate exists in the anhydrous , mono, tri and tetrahydrate forms (mono and tetrahydrate forms are important commercially).
Compare the properties of the hydrates of sodium perborate. The tetrahydrate is prepared from disodium tetraborate pentahydrate, hydrogen peroxide and sodium hydroxide. However, it is not as soluble as the monohydrate nor is it as stable at higher temperatures. Sodium perborate monohydrate is easily prepared by heating the tetrahydrate.

Application:
Bleach teeth with sodium perborate. It is a common active ingredient in regular tooth bleaches and it may also bleach teeth internally. In this case, a preparation of sodium perborate is placed inside a tooth with a non-vital root. The sodium perborate bleaches the tooth from the inside over time and it also serves as an antiseptic and a disinfectant.
