Sodium Sulphate Producers Association

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.

A material that matters

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.

Why it is used

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.

European Quality

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.
