Sodium Sulfate

Sodium sulfate is a sodium-based inorganic compound widely used in industrial and commercial applications for its stability, solubility, and cost-effectiveness. It is most prominently applied in the detergent industry, where it serves as a filler and processing aid in powdered laundry formulations. In glass manufacturing, sodium sulfate helps remove small air bubbles and improves the clarity and strength of finished glass products. It also plays an important role in pulp and paper processing, particularly in kraft pulping operations.

Beyond these core applications, sodium sulfate is employed in textiles for dyeing and finishing processes, in chemical manufacturing as a reactant or stabilizer, and in specialty uses such as thermal energy storage and pharmaceutical formulations. With its versatility, large-scale availability, and adaptability to diverse industrial needs, sodium sulfate remains a vital raw material across sectors including household products, construction, energy, and specialty chemical manufacturing.
