Sodium Phosphate Tribasic Anhydrous (Na₃PO₄) is an inorganic compound and a sodium salt of phosphoric acid. It is a white, odorless, crystalline powder that is highly soluble in water. Often referred to simply as TSP, it is known for its strong alkaline properties and is widely used in industrial and cleaning applications.

Applications:

1. Cleaning and Detergents:
   • Used as a powerful cleaning agent and degreaser in various industrial and household cleaning products.
   • Acts as a builder in laundry detergents to enhance cleaning efficiency by softening water and improving the performance of surfactants.
2. Water Treatment:
   • Used in water treatment facilities to soften water and prevent scale formation.
   • Acts as a corrosion inhibitor and a neutralizing agent for acidic water.
3. Food Industry:
   • Used as a food additive (E339) and pH regulator in processed foods, particularly in baked goods and dairy products.
   • Functions as a leavening agent and emulsifier.
4. Industrial Processes:
   • Utilized in metal cleaning, paint formulations, and as a flux in metal processing.
   • Employed in the production of phosphoric acid and other phosphate compounds.
5. Laboratory Use:
   • Used as a buffer solution in biochemical and microbiological applications to maintain stable pH levels.

Handling and Safety:

• Personal Protection: Wear protective gloves, safety goggles, and suitable clothing to prevent skin and eye contact. Use respiratory protection if dust is generated.
• Inhalation: Avoid inhaling dust, as it can cause respiratory irritation. Use in well-ventilated areas or with appropriate dust control measures.
• Skin/Eye Contact: Can cause irritation. Rinse affected areas with plenty of water. Seek medical advice if irritation persists.
• Spills: Sweep up material carefully to avoid dust generation. Dispose of in accordance with local environmental regulations.
• First Aid Measures:
  • Inhalation: Move to fresh air. Seek medical attention if symptoms persist.
  • Skin/Eye Contact: Rinse with water for at least 15 minutes. Seek medical attention if irritation continues.
  • Ingestion: Rinse mouth and drink plenty of water. Do not induce vomiting. Seek medical help immediately.

Storage:

• Store in a tightly closed container in a cool, dry place, away from moisture to prevent caking or clumping.
• Keep away from acids and acidic substances to avoid neutralization or other chemical reactions.
• Ensure that storage areas are well-ventilated and that the chemical is kept away from heat sources and incompatible materials.

By following these guidelines, you can ensure safe handling and effective use of Sodium Phosphate Tribasic Anhydrous.
