Industrial, Food & Pharmaceutical Grade Anhydrous Sodium Sulfate CAS 7757-82-6 Detergent Builder, Glass Raw Material & Food Additive

Anhydrous Sodium Sulfate (Common Name: Thenardite, CAS:7757-82-6,EINECS:231-820-9, HS Code:2833110000) is a white crystalline inorganic compound. It is produced by purification, concentration and dehydration of natural mirabilite or synthetic raw materials. We supply industrial, food and pharmaceutical grades that comply with GB, FCC, USP and international quality standards. The product dissolves easily in water and is insoluble in ethanol, with stable chemical properties and good compatibility. As a cost-effective basic chemical material, it is widely applied as detergent builder, glass raw material, food additive and pharmaceutical auxiliary in various industries.

Applications
Detergent Industry (Core Application)
It is a classic high-efficiency detergent builder, capable of softening hard water, boosting detergency and preventing redeposition of dirt. Widely added to laundry powder, liquid detergents, soaps and industrial degreasers, it effectively reduces production costs while improving overall cleaning performance.
Glass Manufacturing Industry
Serves as an essential raw material for glass production. It adjusts the viscosity of molten glass, optimizes melting efficiency and enhances product transparency and forming performance. It is extensively used in the production of flat glass, daily-use glassware and decorative glass.
Food Industry
Food grade product acts as processing aid, anti-caking agent and flavor regulator in food manufacturing. It is applied to condiments, meat products, baked goods and other foods, fully meeting strict global food safety standards.
Pharmaceutical & Other Industrial Applications
Pharmaceutical grade is used as diluent, excipient and carrier for tablets, granules and other medicinal preparations. Besides, it is also commonly used in papermaking, textile printing and dyeing, chemical synthesis and leather processing industries.
