Sodium perborate serves as a stable source of active oxygen in many detergents, laundry detergents, cleaning products, and laundry bleaches. [3] It is a less aggressive bleach than sodium hypochlorite and other chlorine-based bleaches , causing less degradation to dyes and textiles .
The structure of the perborate ion ([B 2 O 4 (OH) 4] 2−). This anion is a cyclic molecule and has a tetrahedral molecular geometry at the boron atoms. It contains two bridging peroxide groups ( −O−O− ) and four hydroxyl groups ( −OH ) attached to boron atoms, two per each boron.
Borax (also referred to as sodium borate, tincal (/ ˈ t ɪ ŋ k əl /) and tincar (/ ˈ t ɪ ŋ k ər /)) is a salt (ionic compound), a hydrated or anhydrous borate of sodium, with the chemical formula Na 2 H 20 B 4 O 17. [1] [a] It is a colorless crystalline solid that dissolves in water to make a basic solution.
Sodium borate is a generic name for any salt of sodium with an anion consisting of boron and oxygen, and possibly hydrogen, or any hydrate thereof. It can be seen as a hydrated sodium salt of the appropriate boroxy acid , although the latter may not be a stable compound.
Bleach activation is also known as perhydrolysis. Persalts are inorganic salts that are used as hydrogen peroxide carriers (examples include sodium percarbonate and sodium perborate). Persalts and bleach activators are included together in powder laundry detergents that contain bleach. In the wash, both compounds dissolve in the water.
Sodium percarbonate (Na 2 H 3 CO 6), an adduct of hydrogen peroxide and sodium carbonate ("soda ash" or "washing soda", Na 2 CO 3). Dissolved in water, it yields a solution of the two products, that combines the degreasing action of the carbonate with the bleaching action of the peroxide. Sodium perborate (Na 2 H 4 B 2 O 8).

At one time, sodium perborate was used in detergents. It has since largely been replaced by sodium carbonate sesquiperhydrate. [1]
