📌 Detailed Introduction of Trisodium Phosphate (TSP) Technical Grade

✔ What is Trisodium Phosphate (TSP)?

Trisodium Phosphate (TSP) is a highly alkaline, water-soluble phosphate compound used across multiple industries. It effectively:

  • Enhances cleaning efficiency by breaking down grease, oil, and dirt

  • Acts as a degreasing agent in detergent formulations

  • Softens water by preventing mineral buildup

  • Regulates pH levels in water treatment processes

✔ Forms of Trisodium Phosphate

  1. TSP Anhydrous: A highly concentrated, water-free version of TSP used in industries that require strong alkalinity and effective degreasing.

  2. TSP Dodecahydrate: A hydrated form of TSP that contains 12 molecules of water, making it more stable and easier to handle in cleaning and detergent applications.


📌 Applications of Trisodium Phosphate (TSP) Technical Grade

✔ TSP in the Detergent Industry

  • Degreasing & Cleaning: TSP is an excellent alkaline cleaner used in household and industrial detergents to break down grease, oils, and stains.

  • Water Softening: Helps prevent the formation of scale by binding to hard water minerals, improving detergent efficiency.

  • Emulsifying Agent: Keeps dirt and grease in suspension, preventing redeposition on cleaned surfaces.

✔ TSP in Water Treatment

  • pH Adjustment: TSP is widely used to regulate pH levels in boilers, cooling towers, and municipal water treatment plants.

  • Scale Prevention: By sequestering calcium and magnesium ions, TSP helps reduce scaling and improves water clarity.

✔ TSP in Industrial Cleaning

  • Surface Preparation: Used as a pre-treatment cleaner before painting, removing grease and contaminants from metal and wood surfaces.

  • Heavy-Duty Cleaner: Industrial cleaning solutions incorporate TSP for its ability to dissolve oil, soot, and stubborn residues.

✔ TSP in Food Processing (Limited Use in Some Regions)

  • Acidity Regulator: Used in certain food processing applications to maintain pH balance.

  • Chelating Agent: Helps control metal ions in food formulations, preventing discoloration and spoilage.


📌 Production Method & Raw Materials

✔ Raw Materials Used:

  • Phosphoric Acid (H₃PO₄) – Source of phosphorus

  • Sodium Carbonate (Na₂CO₃) – Provides sodium ions

  • Water – Used in the dodecahydrate form

✔ Production Process:

  1. ReactionPhosphoric acid reacts with sodium carbonate, forming Trisodium Phosphate (TSP).

  2. Crystallization – The mixture is crystallized to produce anhydrous or dodecahydrate forms.

  3. Drying (for Anhydrous) – The anhydrous form undergoes additional drying to remove moisture.

  4. Quality Control & Packaging – The final product is tested and packed in various sizes to meet industrial requirements.
