High-purity anhydrous sodium sulphate (Na₂SO₄) at 99.79% assay with high whiteness — for detergent, kraft paper, glass and textile dyeing. For industrial use only, not food grade; COA on every batch.
LSM supplies anhydrous sodium sulphate (Na₂SO₄) at high purity — a typical assay of 99.79% with high whiteness (94.87%). This is the anhydrous grade, a fine white powder that dissolves readily and carries low chloride, iron, calcium and magnesium — well within specification, as shown on the Certificate of Analysis.
Anhydrous sodium sulphate (also known in the trade as sodium sulfate) is a workhorse across several industries: it is a common filler in powder detergents, a reagent in kraft paper pulping, a raw material in glass manufacturing, and a levelling agent in textile dyeing. This product is for industrial use only and is not food grade; test reports are available on request.
