Sodium Sulphate
Na₂SO₄ | CAS: 7757-82-6 | HS: 28331100
Product Description
Sodium Sulphate is one of the highest-volume commodity chemicals used in detergent manufacturing as a cost-effective, inert filler and carrier that improves powder flowability, handling characteristics, and standard bulk density of detergent powders. In glass manufacturing, it functions as a fining agent (removing gas bubbles from molten glass) and as a supplementary source of sodium oxide. The Glauber's salt decahydrate form has emerging applications in thermal energy storage as a phase-change material. MITCHEM supplies anhydrous detergent and technical grades for export.
Applications by Industry
Primary inert filler in laundry detergent powders, providing bulk, improving flowability, reducing caking, and acting as a carrier for spray-dried surfactant solutions.
Added to glass batch as a fining agent, releasing SO₂ during melting that rises through the melt and carries gas bubbles to the surface, reducing seeds and blisters in finished glass.
Used in the kraft pulping process as a make-up chemical for sulphur and sodium losses in the recovery cycle (green liquor causticisation).
Used in reactive and direct dye processes to promote dye exhaustion onto cotton fibre, increasing dye uptake and improving dyebath efficiency.
