Sodium Sulfate CAS 7757-82-6

Sodium Sulfate Grades Available for Evaluation

YFTDSS can discuss industrial, food-related, and reagent-grade requirements according to the buyer’s application, target purity, impurity limits, documentation requirements, and destination-market regulations.

Industrial Grade Sodium Sulfate Anhydrous

Industrial grade sodium sulfate is suitable for detergent, glass, textile, paper, chemical processing, and other bulk manufacturing applications.

Food Grade Sodium Sulfate / E514(i)

Food-grade sodium sulfate may be used only where the supplied batch, accompanying documentation, and local food regulations meet the buyer’s intended use requirements.

Buyers using sodium sulfate in food production, food ingredients, premixes, or additives should provide the destination country, required standard, target application, and required test limits before ordering.

Reagent Grade Sodium Sulfate

Reagent-grade sodium sulfate is intended for laboratory, analytical, research, and controlled chemical-processing applications where impurity limits and analytical consistency are especially important.

For reagent-grade inquiries, please provide the required standard, test method, impurity limits, annual quantity, and packaging size.

Sodium Sulfate Applications by Industry

Sodium Sulfate for Detergent Manufacturing

Sodium sulfate is widely used in powdered laundry detergents and household cleaning products. It can function as a filler and processing aid, helping improve powder flow, blending consistency, bulk density, and dosing performance during detergent production.

For detergent formulators, the key purchasing considerations are purity, particle size, moisture level, whiteness, storage stability, and compatibility with surfactants and other detergent raw materials. Sodium sulfate can also be purchased together with related alkaline materials such as Soda Ash Dense for selected detergent and cleaning formulations.

Sodium Sulfate for Glass Manufacturing

In glass production, sodium sulfate is commonly used as a refining or fluxing material in the melting process. It can support the removal of small gas bubbles and help improve melt homogeneity during the manufacture of flat glass, container glass, fiberglass, and other glass products.

Glass manufacturers usually evaluate sodium sulfate based on purity, iron content, insoluble matter, moisture, consistency between batches, and its impact on furnace operation. Buyers with strict glass-color or clarity requirements should request a detailed COA before bulk procurement.

Sodium Sulfate for Textile Dyeing and Processing

In textile dyeing, sodium sulfate is used as an electrolyte to support dye exhaustion and improve dye uptake, especially in processes involving reactive dyes. It can help dye molecules move from the dye bath toward the fiber, supporting more efficient coloration and better process control.

Textile processors commonly specify the required purity, particle size, water solubility, chloride level, and iron content. Stable quality is important for reducing shade variation and maintaining reproducible results across dyeing batches.

Sodium Sulfate for Pulp and Paper Processing

Sodium sulfate is used in pulp and paper production, particularly in chemical pulping systems and kraft-process applications. It can be used as a makeup chemical and participates in recovery-related chemical cycles depending on the process design.

Paper mills and pulp producers generally focus on sodium sulfate purity, moisture, insoluble matter, bulk handling method, delivery reliability, and compatibility with existing recovery or chemical-processing systems. Bulk packaging and container-loading plans should be selected according to storage and handling equipment.

Sodium Sulfate for Chemical Processing

Sodium sulfate is also used in chemical manufacturing as a raw material, drying agent, processing aid, and inorganic intermediate. It may be used in dye intermediates, chemical synthesis, water treatment-related formulations, and selected industrial production processes.

For chemical applications, buyers should specify the required grade, impurity limits, particle size, final use, and whether a batch-specific COA is required before production approval.

Packaging Options

Packaging should protect Sodium Sulfate Anhydrous from moisture during storage, inland transport, and sea shipment.

Available packaging options may include:

• 25 kg PP woven bags with PE inner liner
