Sodium Sulphate Anhydrous, SSA

Sodium sulphate (Na₂SO₄) is a white, crystalline solid which is also referred to as Glauber’s salt in its decahydrate form. It is quite soluble in water and is usually of either of the natural mineral origin or an industrial waste product.

SSA has various applications across different industries due to its properties :-

Industrial Applications

  1. Detergents and Cleaning Agents

    • Used as a filler in powdered home laundry detergents to help evenly distribute the active ingredients.

  2. Glass Manufacturing

    • Acts as a fining agent, which removes small air bubbles from molten glass.

  3. Textile Industry

    • Used in the dyeing process to promote even dye absorption in fabrics.

  4. Pulp and Paper Industry

    • Used in the Kraft process for converting wood into wood pulp.
