Pure sodium perborate (NaBO3) is a white, odorless solid under standard conditions. However, a molecule of sodium perborate normally crystallizes with 1, 2 or 4 molecules of water. Sodium perborate monohydrate (NaBO3.H2O) and sodium perborate tetrahydrate (NaBO3.4H2O) have commercial applications, especially as detergents and bleaches. Both forms of sodium perborate are more stable and safer to handle than compounds with similar applications, such as sodium percarbonate and sodium perphosphate.
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 Tetrahydrate is not regulated as dangerous chemical for transportation, but Sodium Perborate Monohydarte is classified as oxidier and the newly allocated UN number as 3377 (as per IMDG CODE) from July 2003.
