Description

Sodium Carbonate Decahydrate is the hydrated crystalline form of soda ash, a fundamental inorganic chemical. This compound is valued for its consistent alkalinity and solubility, making it a versatile processing agent and pH regulator across numerous industries. Key industrial users include manufacturers in the detergent, glass, chemical processing, and water treatment sectors.

Application

• Detergent & Soap Manufacturing: Acts as a water softener, builder, and pH adjuster in powdered laundry and dishwashing detergents.
• Glass Production: Serves as a vital fluxing agent to lower the melting point of silica in the manufacture of flat glass, container glass, and fiberglass.
• Chemical Intermediate: Used in the production of sodium bicarbonate (baking soda), sodium silicates, and various other sodium salts.
• Water Treatment: Employed for pH adjustment and alkalinity enhancement in municipal and industrial water softening and conditioning processes.
• Pulp & Paper Industry: Functions in pulping and bleaching processes, as well as in pH control for papermaking.
• Textile Processing: Used in scouring, dyeing, and finishing operations to neutralize acids and regulate bath pH.
• Food Processing (FCC Grade): Approved for use as an acidity regulator, raising agent, and stabilizer in certain food products.
• Laboratory & Analytical Reagent: Utilized as a standardizing agent and buffer component in analytical chemistry.

Quality Control

Our Sodium Carbonate Decahydrate is produced under a stringent quality management system. Each batch is tested to ensure it meets relevant specifications, including industrial, technical, or Food Chemicals Codex (FCC) grades as required. Certificates of Analysis (COA) documenting purity, assay, and impurity profiles are available for every shipment to guarantee traceability and compliance with your procurement standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in original packaging or sealed containers to prevent caking and loss of crystalline water. Keep away from strong acids.
