Sodium sulfate anhydrous, CAS 7757-82-6, is a white, water-soluble inorganic salt used in powdered detergents, glass manufacture and textile processing.
For industrial purchasing, select the specification around moisture, particle size and application-sensitive impurities. Send us your intended use and quantity to discuss bulk supply, packing and a quotation.
Sodium sulfate anhydrous is also spelled sodium sulphate anhydrous. In powdered detergents, anhydrous sodium sulfate serves as a neutral filler and diluent. It helps set the solids balance of a formulation; it does not provide the cleaning and foaming action of a surfactant. Sodium lauryl sulfate granular has a different role as an anionic surfactant.
Other detergent ingredients are selected for separate functions: sodium carbonate provides alkalinity, sodium tripolyphosphate (STPP) acts as a builder and sequestrant, and sodium silicate is used as a builder and corrosion inhibitor in suitable formulations. These ingredients are not direct substitutes for sodium sulfate, and the finished formulation needs its own performance assessment.
Sodium sulfate is also used in glass manufacture and as an electrolyte in textile dyeing. For glass, impurity control matters to the finished appearance and process. In dye baths, suitability and addition rate depend on the fibre, dye system and process conditions.
This product is the anhydrous salt, Na₂SO₄. Agree the sodium sulfate assay and its reporting basis, moisture, water-insoluble matter, chloride, iron, calcium and magnesium limits needed for your application. Particle-size distribution and bulk density are useful where conveying, blending and dissolution behaviour affect the production line.
A grade name alone does not define all of these acceptance limits. Your quotation should state the agreed specification and acceptance criteria. Share an existing specification or the process requirement so that we can discuss the relevant quality controls.
Lined bags are a common industrial packaging format for this solid. Tell us your preferred packing and handling arrangement; the bag construction, net weight and pallet requirements are agreed with the quotation.
Anhydrous sodium sulfate absorbs moisture. Keep the material dry and the packaging closed to limit moisture uptake, caking and contamination. Control dust during transfer and follow the product Safety Data Sheet and workplace handling procedures.
We can provide a Certificate of Analysis (COA), Technical Data Sheet (TDS) and Safety Data Sheet (SDS) for the offered product. The agreed specification sets the acceptance limits; the applicable COA records the reported analysis for the relevant material.
For a bulk sodium sulfate quotation, send us your application and approximate quantity. Add your target specification, packing preference and destination if available, and we can discuss the remaining order details with you.
