Sodium Sulfate Anhydrous (Na₂SO₄)

Chemical Composition/Properties:

High-grade anhydrous sodium sulfate consists primarily of Na₂SO₄ and contains very little insoluble material, iron, or chloride. High-quality anhydrous sodium sulfate is typically produced by either removing water from the decahydrate (commonly known as Glauber’s salt) or as a by-product of other manufacturing processes (e.g., fertilizers).

Key Characteristics and Industrial Uses

• Water-soluble, neutral ionic salt
• Used as bulking and filler agents in powdered detergents
• Used as an additive in glass manufacturing (salt cake)
• Used as leveling and/or auxiliary agents in textile dyeing
• Used as a chemical raw material for other sulfur-based compounds

Major Industrial Applications

1. Detergent and cleaning industry

• Powdered detergents that contain bulk and filler ingredients
• Enhance powder flow and movement
• Can be used as a carrier for cleaning and descaling products

2. Glass Manufacturing

• Salt cakes to eliminate impurities and foam
• Contribute to the refinement of the glass melt

3. Textile Industry

• Used as leveling agents when dyeing textiles
• Help distribute dye evenly onto fabrics

4. Paper & Chemical Processing

• Adding agents to some paper production formulas
• Used in laboratory and manufacturing administration as stable inorganic salts

5. Other Uses

• Some food and dry application types (only controlled grades)
• Applied to some industrial effluent treatments

How To Determine The Quality Of Sodium Sulfate Anhydrous?

• Na₂SO₄ purity: ≥98% (industrial-grade)
• Insoluble matter: Very small
• Chloride/Iron content: Very low
• Appearance: White, free-flowing powder; no gradient coloration
• Loss on dry (LOD): Substantially Low For Anhydrous Form

Always obtain COA and MSDS from your supplier before purchasing bulk.
