  • Applications

    Sodium sulfate decahydrate (CAS 7727-73-3) is used across several industrial and consumer applications as a processing salt and filler: as a filler and to increase bulk in detergents and cleaning products; as a drying agent in certain purification and solvent-processing steps; as a filler and processing aid in pulp and paper production; as a fining agent and flux in glass manufacturing to control melting behavior and product quality; as a salting-out agent to improve dye uptake on cellulose fibers in textile dyeing and printing; and as a general processing salt or inert carrier in various industrial manufacturing processes, depending on formulation and local regulations.
