Description

Sodium Hypochlorite Pentahydrate is a stable, solid form of sodium hypochlorite, offering a safer and more convenient alternative to liquid bleach solutions for industrial applications. Its pentahydrate crystalline structure provides enhanced stability and precise dosing capabilities, which is critical for controlled oxidation and disinfection processes. This compound is essential for manufacturers and processors in the water treatment, pulp & paper, textile, and specialty chemical synthesis industries who require a reliable and consistent source of active chlorine.

Application

• Water Treatment & Disinfection: Used as a solid bleach source for sanitizing potable water, swimming pools, and industrial process water systems.
• Pulp & Paper Bleaching: A key oxidizing agent in the bleaching of wood pulp to achieve high brightness levels in paper production.
• Textile Processing: Employed for bleaching natural fibers like cotton and linen, as well as for stain removal and color stripping.
• Chemical Synthesis: Serves as a selective oxidizing agent in the production of pharmaceuticals, agrochemicals, and other fine chemicals.
• Food & Beverage Industry Sanitation: Used in sanitizing food contact surfaces and equipment in processing plants (subject to appropriate grade specifications).
• Municipal & Industrial Wastewater Treatment: Effective for odor control and the oxidation of contaminants in effluent streams.
• Cleaning-in-Place (CIP) Systems: Provides a stable solid formulation for automated cleaning solutions in dairy, beverage, and pharmaceutical facilities.

Quality Control

Our Sodium Hypochlorite Pentahydrate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for active chlorine content, stability, and purity. Certificates of Analysis (COA) documenting key parameters are provided with every shipment. We can supply grades tailored to meet various industrial standards, including technical and high-purity specifications.

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 such as acids, reducing agents, and organic compounds. Due to its oxidizing nature and sensitivity to moisture and heat, it is recommended to store at controlled room temperature (15-25°C) to maintain stability and shelf life. Keep containers tightly sealed when not in use.
