Grades We Manufacture :
• Tetra sodium Pyrophosphate Anhydrous Industrial Grade
• Tetra Sodium Pyrophosphate Crystal Industrial Grade

Formulation :
2H3PO4 + 4NaOH = Na4P2O7 + 5H2O
2H3PO4 + 2Na2CO3 = Na4P2.O7 + 2CO2 + 3H2O

2H3PO4 + 4NaOH + 5H2O = Na4P2O7.10H2O
2H3PO4 + 2Na2CO3 + 7H2O = Na4P2O7.10H2O + 2CO2

Tetra sodium pyrophosphate, also known as Sodium Pyro phosphate, Tetra sodium phosphate or TSPP, is achemical compound composed of pyrophosphate and sodium ions.

Application :

• Tetra Sodium pyrophosphate is used as a buffering agent, also as an emulsifier and as a dispersing agent
• Tetra Sodium Pyrophosphate also used as a thickening agent and also often used as a food additive
