Anhydrous Sodium Sulphate

Anhydrous Sodium Sulphate (also known as Glauber's Salt or Sodium Sulphate Anhydrous) is a vital inorganic chemical raw material with excellent dispersing, filling, and stabilizing properties. We select high-grade raw materials and process them through a closed-loop fully automated purification production line. Our products are widely used in the detergent and daily chemical industry, textile printing and dyeing, glass manufacturing, livestock and poultry feed, and various other industrial sectors.

Key Values:

Excellent dispersing and filling performance: reduces raw material costs in the detergent, textile, and printing industries

Stabilizing agent: regulates glass melting temperature in glass production, reducing furnace energy consumption

Mineral nutrient supplement: provides sodium and sulfur trace elements for livestock and poultry feed

Cost-effective inorganic raw material: replaces expensive additives, reducing overall factory production expenses

Product Core Advantages

Strict Impurity Control We employ a closed-loop fully automated purification production line to rigorously remove calcium, magnesium, and chloride ion impurities. Our high-grade product has a chloride ion content of ≤0.3%, far superior to general industry standards, effectively reducing impurity interference in downstream production.

Customizable Particle Sizes with Anti-Caking Properties We support customization of multiple particle size specifications: coarse crystals, medium powder, 200-mesh fine powder, and 325-mesh ultra-fine powder. Food/feed-grade anti-caking agents can be added upon request. Our products remain loose and free from agglomeration or caking even after long-distance ocean shipping.

Consistent Batch-to-Batch Quality We utilize a computer-automated batching system combined with a continuous drying integrated production line, ensuring that purity deviations for each batch are controlled within ±0.1%. Finished product samples from all batches are retained in our laboratory for 24 months, available for traceability and re-inspection at any time.

Flexible Customization Options We offer customizable purity, whiteness, particle size, moisture content, and packaging bag printing content. For long-term large-volume cooperation, we can arrange small-batch trial orders in advance.

Technical Specifications

Industrial Grade Anhydrous Sodium Sulphate Standard Specifications

Feed Grade Sodium Sulphate Standards Our feed grade product complies with China GB 7300 Feed Additive National Standard and EU feed import access requirements. Heavy metal content (lead, arsenic, cadmium) is strictly controlled, with no toxic or harmful residues, specifically designed for ruminant livestock and poultry feed processing.

Application Fields

Detergent & Daily Chemical Industry (Largest Application) As a core filler and dispersing agent in laundry powders, liquid detergents, soaps, and stain removers, it reduces the cost of surfactants while improving cleaning and stain-removing effectiveness.

Textile Printing & Dyeing Industry Used as a leveling agent and dye-fixing auxiliary, it removes excess dye residues from fabric surfaces, ensuring even coloration and no color deviation in textiles.

Glass Manufacturing Industry Regulates glass melting temperature, reduces furnace energy consumption, and improves glass light transmittance. Suitable for flat glass, container glass, and optical glass production.

Livestock & Poultry Feed Additive Industry Supplies sodium and sulfur nutrients to dairy cows, beef cattle, sheep, and poultry, improving feed conversion rates and increasing milk and egg production.

Other Industrial Applications Paper-making auxiliaries, battery raw materials, leather tanning agents, concrete admixtures, mineral flotation reagents, and snow-melting agent raw materials.

Frequently Asked Questions

What is the difference between industrial grade and feed grade sodium sulphate? Feed grade strictly limits heavy metal content and meets feed safety certifications, intended only for livestock and poultry nutritional supplementation. Industrial grade is suitable for detergent, textile, and glass production and should not be added to animal feed.

Will the product absorb moisture and cake during long-distance ocean shipping? Our products are treated with safe anti-caking agents, and each bag is lined with a thickened moisture-proof PE film. When stored in a dry warehouse after arrival at the destination, the product will not show obvious caking for up to two years.

What documents can you provide for EU customs clearance? Industrial grade: REACH Registration Certificate, SGS Test Report, ISO Certificates, MSDS, COA. Feed grade: additionally includes Feed Production License, Halal Certification, and EU Feed Additive Access Documentation.

What is the minimum order quantity? In-stock products: minimum 1 ton; custom-specification products: minimum 20 tons; trial orders have no MOQ requirement, only international courier shipping fees apply.

What particle size specifications are available? Coarse crystals, medium powder, 200-mesh fine powder, and 325-mesh ultra-fine powder. Multiple particle sizes can be mixed in the same container upon request.

How should anhydrous sodium sulphate be stored to extend its shelf life? Store in a cool, dry, well-ventilated warehouse, protected from rain and high-humidity environments. Seal the packaging promptly after partial use. Do not store together with acidic chemical raw materials.

Are anhydrous sodium sulphate and Glauber's salt the same product? Yes. Anhydrous sodium sulphate is the chemical name, while Glauber's salt (or sodium sulphate anhydrous) is the common trade name used in the global chemical raw material market.
