FSiix Resources sources and trades Sodium Sulphate (Na₂SO₄) — a white crystalline inorganic salt valued for its low hygroscopicity, chemical stability, and compatibility with alkaline and neutral formulations. Supplied from certified Indian production in anhydrous (salt cake) and Glauber's Salt decahydrate grades, our sodium sulphate meets IS 255, IS 256, and international specifications for detergent manufacturing, textile dyeing, glass fining, and paper and pulp processing, and moves under standard industrial packing and transport worldwide.
FSiix's sodium sulphate programme draws on certified Indian manufacturing to supply anhydrous sodium sulphate (also known as salt cake or SSA) and Glauber's Salt decahydrate from a single, audited source. The anhydrous form offers enhanced storage stability and consistent performance in applications requiring controlled moisture, while its uniform particle structure supports efficient large-scale industrial processing.
Sodium sulphate's low hygroscopicity and high compatibility with alkaline and neutral formulations make it the standard filler and processing aid across detergent, textile, glass, and paper manufacturing. FSiix supplies every grade against IS 255 (anhydrous technical grade), IS 256 (Glauber's Salt technical), and buyer-specified assay limits, backed by batch certificates of analysis for consistent, reliable supply.
FSiix's sodium sulphate supply runs under continuous crystallisation production and batch-certified quality control, from process liquor through to the graded, export-ready salt.
Sodium sulphate liquor is generated as a byproduct of several industrial processes, including synthetic detergent (HCl) manufacture, viscose rayon production, and various acid-neutralisation reactions using sulphuric acid and sodium hydroxide or sodium chloride, producing a sodium sulphate-rich mother liquor.
The liquor is evaporated and cooled to crystallise sodium sulphate decahydrate (Glauber's Salt, Na₂SO₄·10H₂O), with impurities such as chloride and iron purged from the mother liquor circuit to maintain product purity.
Glauber's Salt crystals are centrifuged and thermally dehydrated to produce anhydrous sodium sulphate (salt cake), then screened to target particle size and whiteness. Every batch is assayed for Na₂SO₄ content, chloride, iron, and moisture against IS 255 / IS 256 before certification and dispatch.
FSiix's sodium sulphate supplies detergent manufacturers, textile dyers, glassmakers, and paper producers — matched to the grade each process calls for.
Anhydrous salt cake and Glauber's Salt decahydrate from one certified Indian source mean customers can match the exact form and moisture tolerance their process requires without splitting orders across suppliers.
Every batch is assayed for Na₂SO₄ content, chloride, iron, and moisture against IS 255 (anhydrous technical grade), IS 256 (Glauber's Salt technical), and buyer specifications, with certificates of analysis issued ahead of shipment.
HDPE bags, jumbo bags, and bulk container options are matched to buyer volume, with consistent particle size and whiteness supporting reliable performance in detergent and textile formulations.
Sodium sulphate demand spans detergent manufacturing, textile dyeing, glass fining, and kraft pulp processing, with India among the leading production and consumption centres, supplying both domestic industry and export markets across Asia, Africa, and the Middle East.
Sodium sulphate pricing moves with feedstock and energy costs, grade, and packing format, and varies meaningfully between anhydrous salt cake and Glauber's Salt decahydrate, so we don't publish a static reference price here — anything printed on a page would likely be stale within days.
