Sodium Sulfate (CAS: 7757-82-6) is a white crystalline inorganic salt widely used across industrial, food, and consumer sectors. Composed of sodium and sulfate ions, this water-soluble compound occurs naturally in mineral deposits and brines, and is also recovered as a by-product of chemical processing. Its value lies in a combination of high purity, chemical stability, low cost, and excellent compatibility with a broad range of formulations. In detergent manufacturing it serves as a filler and processing aid, improving powder flow and dissolution. The pulp and paper industry relies on it in the kraft pulping process to replenish sulfate ions, while glass manufacturers use it as a fining agent to remove bubbles from molten glass. Textile dyers employ it as a leveling agent that promotes even color uptake on fibers. In food applications, food-grade material is used as a processing aid and carrier. Its consistent quality, easy handling, and bulk availability make sodium sulfate a dependable raw material for large-scale industrial production.

– Detergent and Cleaning Products: Used as an inert filler and processing aid in laundry powders and tablets, improving flowability, dispersion, and dissolution while reducing formulation cost.
– Pulp and Paper Industry: Employed in the kraft pulping process to replenish sulfate ions and maintain chemical balance, supporting efficient cellulose fiber production.
– Glass Manufacturing: Applied as a fining agent in molten glass to remove entrapped air bubbles and defects, improving optical clarity and product quality.
– Textile Dyeing and Processing: Functions as a leveling agent and salt additive in dye baths to promote uniform color absorption and fixation on cotton and blended fibers.
