High Oxygen Content Natrium Perboricum For Bleaching Powder Production

Sodium Perborate Monohydrate

Specification:

Sodium perborate usually exists in two forms, tetrahydrated and monohydrated. Sodium perborate monohydrate is dehydrated from perborate tetrahydrate. It is widely used in hot climates, or in markets where washing is carried out in cool water.

Sodium perborate monohydrate is particularly suitable for use at high ambient temperatures. The high rate of dissolution, ideal for use in cold wash temperatures ensures a rapid release of hydrogen peroxide into solution, providing rapid generation of peracid from the bleach activators being used (typically known as TAED: TetraAcetyEthyleneDiamine, NOBS or DECOBS). This ensures that the bleach works throughout the whole wash cycle. Sodium perborate is also ideal for use in tablet formulations due to its high available oxygen content, and a low moisture content.

Sodium perborate serves as a stable source of active oxygen in many detergents, laundry detergents, cleaning products, and laundry bleaches. It is a less aggressive bleach than sodium hypochlorite and other chlorine-based bleaches, causing less degradation to dyes and textiles. Borates also have some non-oxidative bleaching properties.

Sodium perborate releases oxygen rapidly at temperatures over 60°C. To make it active at lower temperatures (40-60°C), it has to be mixed with a suitable activator, typically tetraacetylethylenediamine (TAED).

Sodium perborate is also present in some tooth bleaching formulas for non vital root treated teeth. The compound is inserted in the root canal and left in place for an extended period of time to allow it to diffuse into the tooth and bleach stains from the inside out.

The compound has antiseptic properties and can act as a disinfectant. It is also used as a "disappearing" preservative in some brands of eye drops. Sodium perborate is also used as an oxidizing reagent in organic synthesis. For example, it converts thioethers into sulfoxides and sulfones.

Sodium Perborate Tetrahydrate is not regulated as dangerous chemical for transportation, but Sodium Perborate Monohydarte is classified as oxidizer and the newly allocated UN number as 3377 (as per IMDG CODE) from July 2003.
