Description

Sodium Perborate Trihydrate is a stable, solid source of active oxygen widely used as a bleaching and oxidizing agent. Its controlled release of hydrogen peroxide makes it a valuable and safer alternative to liquid peroxides in many formulations. This compound is essential for manufacturers in the detergent, textile, personal care, and pulp & paper industries seeking effective and stable oxidizing performance.

Application

• Detergent & Cleaning Formulations: A key bleaching component in laundry detergents, dishwasher tablets, and industrial cleaners.
• Textile Processing: Used for bleaching natural fibers like cotton and linen at elevated temperatures.
• Hair Care Products: Serves as the active agent in hair lighteners and certain hair coloring systems.
• Pulp & Paper Industry: Employed in the bleaching of wood pulp to achieve high brightness.
• Organic Synthesis: Acts as a mild and selective oxidizing agent in various chemical reactions.
• Dental Care Products: A component in some tooth whitening powders and denture cleansers.
• Water Treatment: Used for oxidation processes in certain wastewater treatment applications.
