China, the United States, and Germany are the leading exporters of sodium sulfate, collectively accounting for a substantial share of global shipments, while India, Mexico, and Brazil represent the largest importers. These countries reflect both mature industrial demand and growing downstream applications in detergents, glass, and textiles. Global sodium sulfate trade volumes have remained relatively stable over the past three years, with modest regional shifts in sourcing—particularly increased imports by Mexico and India from U.S. and German suppliers—coinciding with fluctuations in sodium sulfate prices tied to raw material costs and logistics constraints.
Sodium sulfate is a white, crystalline, odorless solid that exists in anhydrous and hydrated (decahydrate) forms; the anhydrous form melts at 884 °C and is non-volatile. It is an inorganic salt, specifically the sodium salt of sulfuric acid. Sodium sulfate serves primarily as a filler and processing aid in detergent manufacturing, and as a raw material in the production of sodium sulfide, glass, and paper pulp. It is widely used in the textile industry for dye leveling and in the manufacture of synthetic detergents, kraft paper, and certain specialty chemicals.
It can be mainly used as the filler of synthetic detergent. Paper industry applies it for the cooking agent during the manufacture of sulfate pulp. Glass industry uses it as substitute of soda. Chemical industry applies it as the raw material for the manufacturing of sodium sulfide, sodium silicate and other chemical products. Textile industry applies it for the formulation of Vinylon spinning coagulation bath. The pharmaceutical industry applies it as laxatives. It can also be used in non-ferrous metallurgy and leather.
It appears as white monoclinic crystal or powder. It can be dissolved in water with the aqueous solution being alkaline. IT can be dissolved in glycerol and is insoluble in ethanol.
