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.

⚙️ Production Method

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.

🏭 Use Cases by Industry

🧼 Industrial Cleaning

• Surface degreasing before painting or coating

• Cleaner in laundry, dishwashing, and janitorial applications

• Metal pre-treatment and boiler cleaning

🧪 Chemical & Water Treatment

• pH buffer in textile and dye industries

• Precipitates heavy metals and removes scale in boilers

• Controls water hardness

🍖 Food Processing (Food Grade TSP)

• Emulsifier and moisture binder in meats and seafood

• Prevents discoloration in potatoes and other vegetables

• Used as acidity regulator (E339) in soft drinks and cheese processing

❓ Frequently Asked Questions (FAQs)

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.

4. Does Cavin Resource ship internationally?

Answer:
Absolutely. We offer door-to-port logistics, SGS inspection, and export-standard packaging worldwide.
