Sodium Perborate Tetrahydrate 95% Min with 10% Active Oxygen for Detergent Bleach

White monoclinic crystalline particles or powders. Melting point 63ºC. Soluble in acid, alkali and glycerin, slightly soluble in water, the solution is alkaline (pHl0 ~ 11), the aqueous solution is unstable, and it is easy to release reactive oxygen species. In cold and dry air, sodium perborate with higher purity is more stable. Decomposes at 40 ° C or in humid air and releases oxygen. At 63ºC, it dissolves in its own crystal water and decomposes, and forms a viscous solid block. Above 70ºC, three crystalline waters are lost to form a monohydrate. It is easy to decompose at high temperature and in the presence of free alkali. When treated with concentrated sulfuric acid, oxygen and ozone are released. It is also easily decomposed by other substances such as lead oxide, manganese dioxide, copper oxide, cobalt oxide and platinum black.

Commonly used as an oxidizer of Yindanshilin dye color, bleaching and degreasing of original cloth, used as a disinfectant and fungicide in medicine, and can also be used as a mordant, detergent additives, deodorants, additives of electroplating solution, analytical reagents, organic synthesis polymerization agents, and toothpaste, cosmetics and so on.

Specification:

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, 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.
