Product Application of Sodium perborate monohydrate CAS#10332-33-9
Cleaning and Bleaching: Laundry Detergent Additive: Widely used in concentrated laundry detergents, stain removers, and dishwasher detergents as a stable source of active oxygen. Low-Temperature Activation: Rapidly releases oxygen at temperatures above a certain range; when combined with activators (such as TAED), it can function at lower temperatures.
Oral Care: Used in denture cleaners and teeth whitening formulations. A key ingredient in oral disinfectant mouthwashes (such as Amosan) for treating mouth ulcers and gingivitis.
Industrial Applications: In the textile industry, it is used as a bleaching agent, gentler than chlorine bleach and less damaging to fabrics. In pharmaceuticals, it is used as a "disappearing" preservative in certain eye drops.
