Description

Sodium Sulfate is an essential inorganic salt widely recognized for its versatility and utility across numerous industrial processes. Its primary value lies in its role as a cost-effective and efficient drying agent, processing aid, and raw material. This makes it a critical component for manufacturers in the detergent, textile, glass, and chemical synthesis industries. We supply high-purity Sodium Sulfate CAS NO 7757-82-6 to meet the stringent demands of global B2B markets.

Application

• As a key filler and processing aid in the manufacture of powdered laundry and dishwashing detergents.
• In the textile industry as a leveling agent and electrolyte in dyeing processes.
• As a fining agent to remove small air bubbles in the production of glass.
• As a drying agent (desiccant) for organic liquids in laboratory and industrial settings.
• In the pulp and paper industry within the Kraft process for wood pulping.
• As a raw material for the synthesis of other sodium-based chemicals and sodium sulfide.
• In food processing (food-grade) as an anti-caking agent, processing aid, and firming agent.
• In veterinary and pharmaceutical applications as an excipient or saline laxative.

Quality Control

Our Sodium Sulfate is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and reliability. We offer various grades, including industrial, technical, food-grade (FCC), and USP/EP pharmaceutical grades, each meeting specific industry standards. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are kept tightly sealed to prevent caking and absorption of atmospheric moisture. Keep away from incompatible materials such as strong acids.
