Description

Sodium Perborate Tetrahydrate 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 industrial and consumer formulations. This compound is essential for manufacturers in the detergent, textile, personal care, and pulp & paper industries seeking effective, stable, and easy-to-handle oxidizing solutions.

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 low temperatures.
• Personal Care Products: Employed in tooth whitening powders, hair lighteners, and acne treatment formulations.
• Pulp & Paper Industry: Acts as a bleaching agent in the production of mechanical and chemical pulps.
• Organic Synthesis: Serves as a mild and selective oxidizing agent in various chemical reactions.
• Disinfection & Sanitization: Used in formulations for surface disinfectants and wound cleansers.
• Dye & Colorant Oxidation: Facilitates the development and fixing of certain dyes.

Quality Control

Our Sodium Perborate Tetrahydrate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for active oxygen content, purity, and physical properties. Certificates of Analysis (COA) documenting these results are provided with every shipment to guarantee traceability and consistency for your production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent caking and decomposition. Store separately from strong acids, reducing agents, and organic materials.
