Basic Information

Sodium carbonate
Na₂CO₃
White powder

Sodium carbonate is a white, hygroscopic alkaline material that dissolves in water to provide basic solutions. It serves as a silica flux in glassmaking and an alkalinity source in detergents, water treatment, pulp processing, and textiles. In suitable food-processing grades, it also adjusts acidity and contributes to texture development in prepared foods.

product description

High Solubility and Effective Alkalinity:Easily dissolves in water to form a moderately alkaline solution, providing efficient pH control and cleaning performance.


Essential Flux for Glass Manufacturing:Acts as a key flux in silica melting, with about half of global production used in glass production, ensuring high industrial demand and proven reliability.


Wide Industrial Versatility:Broadly applied in pulp and paper, textiles, water treatment, soaps, detergents, and drain cleaning, making it a multi-purpose basic chemical.


Strong Reactivity and Cleaning Power:As a weakly alkaline compound, it can effectively break down tissue and dissolve amphoteric metals and their compounds, serving as a highly efficient cleaning and treatment agent.

Product Description of Sodium carbonate CAS#497-19-8

Sodium carbonate (Na₂CO₃) is a white, hygroscopic alkaline powder that forms basic aqueous solutions. Approximately half of global production is used in glass manufacturing (as a silica flux), with the remainder applied in pulp/paper, textiles, water treatment, detergents, food processing and general industrial cleaning.


Product Application of Sodium carbonate CAS#497-19-8

Sodium carbonate is a water-soluble alkaline crystalline compound. In food processing, it acts as a pH regulator, antioxidant, curing agent and processing aid, used in instant soups, alginate dessert gels, puddings, sauces and baked goods to adjust acidity, improve texture and enhance flavor.
