High Purity Anhydrous Sodium Sulfate Manufacturer – CAS 7757-82-6
Sodium sulfate anhydrous CAS 7757-82-6 offers ≥99% purity as a stable white crystalline powder or granule. Its sodium sulfate structure supports detergent filling, textile leveling, glass fining, and pulp processing. At the same time, its neutral and non-corrosive characteristics help maintain predictable handling in large-scale industrial production.
Sodium Sulfate consists of sodium ions (Na⁺) and sulfate ions (SO₄²⁻), forming a highly stable inorganic compound with strong industrial usability. Because of its chemical stability and neutral characteristics, Na₂SO₄ is widely used as a filler, leveling agent, fining agent, and processing additive in multiple industries.
Our industrial-grade Anhydrous Sodium Sulfate is manufactured according to strict quality standards, meeting GB/T 6009-2014 specifications to ensure consistent purity, stable performance, and reliable results in large-scale industrial applications.

Sodium Sulfate Anhydrous for Detergents and Industrial Processing
Sodium sulfate anhydrous is a stable inorganic salt used in detergent production, textile dyeing, glass manufacturing, pulp processing, and chemical production. This Na₂SO₄ grade carries CAS 7757-82-6 and provides ≥99% purity for industrial formulations that need consistent salt content and reliable handling.
The compound contains sodium ions and sulfate ions. When used in production systems, it offers neutral behavior, strong chemical stability, and good water solubility. Because it does not act as a strongly acidic or alkaline material, manufacturers can apply it in many processes that require stable inorganic salt performance.
Stable Na₂SO₄ Grade for Filler, Leveling, and Fining Use
Detergent producers often use sodium sulfate anhydrous as a filler and processing aid. It helps adjust powder bulk, supports blending uniformity, and improves handling during detergent manufacturing. At the same time, textile dyeing plants use it as a leveling agent to help support more controlled dye distribution.
Glass manufacturers use sodium sulfate as a fining agent in selected production processes. It helps reduce bubbles and supports melt clarification during glassmaking. Pulp and paper producers may also apply it in processing systems where sodium sulfate chemistry fits production needs.
The product appears as a white crystalline powder or granule. This physical form supports storage, feeding, and bulk handling in different factory systems. In practice, stable particle quality can help reduce variation during continuous production.
Vanchor supplies ≥99% sodium sulfate anhydrous with quality control aligned with industrial requirements, including GB/T 6009-2014 specifications where applicable. With export packaging and bulk supply support, Vanchor helps manufacturers access a stable Na₂SO₄ source for detergents, textiles, glass, paper, and chemical manufacturing.

Sodium Sulfate Anhydrous FAQs
01
What Is Sodium Sulfate Anhydrous Used For?
Sodium Sulfate Anhydrous is widely used as a filler in powder detergents, a leveling agent in textile dyeing, and a processing aid in the glass, paper, and chemical industries. Its stable chemical properties and excellent water solubility make it suitable for large-scale industrial applications.
02
What Is the Difference Between Sodium Sulfate Anhydrous and Glauber's Salt?
Sodium Sulfate Anhydrous (Na₂SO₄) contains no crystal water, while Glauber's Salt (Na₂SO₄·10H₂O) contains ten molecules of water. The anhydrous form is preferred for detergent manufacturing, textile processing, and glass production because it offers higher active content and better storage stability.
03
How Should Sodium Sulfate Anhydrous Be Stored?
Sodium Sulfate Anhydrous should be stored in a dry, well-ventilated warehouse and kept in tightly sealed packaging to prevent moisture absorption and contamination. Under proper storage conditions, it maintains stable quality and is suitable for long-distance export and bulk industrial use.
