Product Application of Sodium perborate monohydrate CAS#10332-33-9

Cleaning and Bleaching   As a laundry detergent additive, it is widely used in concentrated laundry detergents, stain removers and dishwasher detergents as a stable active oxygen source. It features low-temperature activation, releasing oxygen rapidly above a specific temperature range; when compounded with activators such as TAED, it can exert bleaching effect at lower temperatures. Oral Care   It is applied in denture cleaners and teeth whitening products, and serves as a key ingredient in oral disinfectant mouthwashes like Amosan for relieving mouth ulcers and gingivitis. Industrial Applications   In the textile industry, it is used as a mild bleaching agent, causing less damage to fabrics than chlorine-based bleach. In the pharmaceutical field, it acts as a degradable preservative in certain eye drop formulations.
