Sodium Sulfate: Inorganic Salt for Industrial and Osmotic Applications
Sodium sulfate (Na₂SO₄) is an inorganic salt available in anhydrous form (thenardite) and as the decahydrate (Glauber’s salt). The anhydrous form is widely used as a drying agent in organic chemistry and as a filler in detergent formulations. The decahydrate historically served as an osmotic laxative. Sodium sulfate is one of the highest-volume inorganic chemicals traded globally.

Formulation Applications
In pharmaceutical manufacturing, anhydrous sodium sulfate is used as a drying agent in organic synthesis and extraction processes. Glauber’s salt (the decahydrate) has a long history as a saline osmotic laxative, though it has largely been replaced by PEG-based preparations. In the detergent industry, sodium sulfate serves as a cost-effective filler and processing aid in powder detergent formulations. It is also used in glass manufacturing, textile dyeing (as a levelling agent), and in Kraft paper pulping. In analytical chemistry, the anhydrous form is the standard drying agent for organic extracts.
