Trisodium Phosphate (TSP) – Industrial & Food Grade Cleaner

Trisodium Phosphate (TSP) is an inorganic, highly alkaline compound with the chemical formula Na₃PO₄. It is widely used in cleaning formulations, metal treatment, pH regulation, and food processing (in its food-grade form). It is available in crystalline anhydrous and dodecahydrate (12H₂O) forms.

TSP is known for its strong degreasing ability, making it ideal for industrial cleaning, especially in textile mills, metal finishing, dishwashing powders, and paint preparation. In the food industry, food-grade TSP is used as a buffering agent, emulsifier, and moisture retainer in meats and seafood.

At Cavin Resource, we supply high-purity industrial and food-grade TSP with international compliance, bulk packaging, and worldwide shipping.

Neutralization of Phosphoric Acid

• Produced by reacting phosphoric acid (H₃PO₄) with sodium carbonate (Na₂CO₃) or sodium hydroxide (NaOH) under controlled temperatures.

• Resulting trisodium phosphate is then crystallized into anhydrous or hydrated forms, depending on the drying process.

1. What is the difference between anhydrous and dodecahydrate TSP?

Answer:
Anhydrous TSP contains no water molecules, while dodecahydrate contains 12 water molecules, making it appear crystalline and more soluble in water. The choice depends on application and solubility needs.

---

2. Is TSP banned in detergents?

Answer:
In some regions, phosphate-based detergents are restricted due to environmental regulations. However, TSP is still widely used in industrial and non-domestic applications. We also offer eco-safe alternatives upon request.

---

3. Can TSP be used in food?

Answer:
Yes, food-grade TSP (E339) is approved by FDA and EU for use as a food additive, emulsifier, and acidity regulator. It must not be confused with industrial-grade TSP.
