Applications

Sodium perborate tetrahydrate is considered as a source of active hydrogen used in detergents, cleaning products, laundry detergents and bleaches. It finds application as a tooth bleaching agent utilized for tooth. It has antiseptic properties and acts as disinfectant as well as preservative in eye drops. Further, it is mixed with suitable activator, tetraacetylethylenediamine in order to release oxygen at lower temperatures.

Notes

Moisture sensitive.Incompatible with metals, metallic salts, acids, bases and reducing agents.
