Sodium sulfate (Na2SO4) is a white, crystalline compound that is commonly used in various industries and applications.

  • 1. Detergents and Cleaning Products: Sodium sulfate is used as a filler and a viscosity regulator in the production of powdered detergents and cleaning products. It helps in controlling the density and flow properties of the products.

  • 2. Textile Industry: In the textile industry, sodium sulfate is used in the dyeing process. It assists in enhancing the absorption of dyes by the fibers, improving color uniformity and fastness.

  • 3. Pulp and Paper Industry: Sodium sulfate is utilized in the production of paper and cardboard. It helps in breaking down wood fibers and reducing the formation of foam during the pulping process.

  • 4. Glass Manufacturing: Sodium sulfate is added to glass formulations to lower the melting point of the mixture and improve the workability of the glass. It also aids in the removal of air bubbles and enhances the clarity of the glass.

  • 5. Chemical Manufacturing: Sodium sulfate is a versatile compound used as a raw material or reagent in various chemical processes. It is involved in the production of sodium sulfide, sodium carbonate, sodium silicate, and other chemicals.

  • 6. Food Additive: Sodium sulfate is used as a food additive in some processed foods. It may act as a texturizer, stabilizer, or anti-caking agent in certain food products

  • 7. Pharmaceutical Applications: Sodium sulfate has limited applications in the pharmaceutical industry. It is sometimes used as a laxative or in oral solutions for gastrointestinal procedures.

  • 8. Water Treatment: Sodium sulfate is employed in water treatment processes, particularly in the removal of specific ions and contaminants from water sources.
