An essential material,
made to a higher standard.
Sodium sulphate is one of industry's quiet enablers — present in the detergents that clean our clothes, the glass we look through every day, and the fibres used in textile. European producers deliver it with the purity, consistency and traceability that modern manufacturing demands.

Sodium sulphate (Na₂SO₄) is an inert, free-flowing white salt that has shaped industrial chemistry since 1625. Today, European producers supply it to detergent formulators, the glass industry and dozens of downstream processes — quietly, reliably, and to specifications that few alternatives can match.
Functional benefits, proven by chemistry.
Sodium sulphate's value is not abstract — it is measured in cleaner laundry, stronger glass and consistent industrial output.
Pure and inert
A non-hazardous mineral salt with stable composition and reliable performance across formulations.
Consistent supply
Co-produced and mined under controlled processes, available all year in predictable volumes.
Chemically helpful
Improves dissolution, lowers surface tension and supports biodegradation in detergents.
Locally produced
European production means short delivery distances, low transport CO₂ and supply security.
Where you find it.
Detergents remain the largest market — accounting for 70 to 80 % of demand. Glass, pulp, textile dyeing and a long tail of chemical processes complete the picture.

Detergents
70–80%Soluble filler, flow agent and anti-caking aid. Helps active ingredients dissolve and dose correctly.

Glass
RefiningA source of sodium and a refining agent that prevents bubbles and produces stronger, defect-free glass.

Fibres & dyeing
ProcessFixes colourants in textile fibres and is recovered as a co-product of viscose manufacturing.
A standard of purity you can plan around.
European sodium sulphate is produced under controlled processes that yield exceptionally high Na₂SO₄ content — up to 99.9% — with tightly bounded levels of moisture, chlorides and trace metals. For formulators and process engineers, this means fewer surprises and more reliable end-product performance.
