About this grade
Origin: Algeria.
Anhydrous sodium sulphate sourced from a certified Algerian producer via natural salt extraction. A free-flowing white powder with ≥99.0% Na₂SO₄ content, ≥92 Hunter Lab whiteness, and trace metals (Fe, Al, Zn) each capped at 5 ppm. Widely used as a filler and bulking agent in powder detergents, as a flux in glass and fiberglass manufacturing, in the Kraft pulping process, and as a dye-leveling agent in textile dyeing.
