Usage

Uses

Used in Antiseptic Applications:
Sodium perborate is used as an antiseptic due to its ability to release oxygen, which helps in killing bacteria and other microorganisms.
Used in Denture Cleaning:
Sodium perborate, both anhydrous and in the form of tetrahydrate and monohydrate, is used as a denture cleaner. Its oxygen-releasing properties help in removing stains and disinfecting the dentures.
Used as a Bleaching Agent:
Sodium perborate, monohydrate (NaBO3·H2O), is used as a bleaching agent due to its ability to release hydrogen peroxide when dissolved in water. This property makes it effective in whitening fabrics and other materials.
Used in Various Industries:
Sodium perborate is used in different industries such as cleaning products, laundry detergents, and personal care products due to its effective cleaning, disinfecting, and bleaching properties.
