Tetrapotassium Pyrophosphate, also known as TKPP, appears as a white powder with high solubility in water. It is widely used in a broad range of industrial applications.
Tetrapotassium Pyrophosphate is manufactured through neutralization and calcination reaction between phosphate and potassium hydroxide. Tetrapotassium Pyrophosphate, in the form of white crystalline powder, is obtained at the end of the process after the product is left to cool and crystallize.
H3PO4 + 2KOH → K2HPO4 + 2H2O
2K2HPO4 → K4P2O7 + H2O
Tetrapotassium Pyrophosphate is often used in the food industry as chelating agents and emulsifiers. It also has quality improving properties which sustains the freshness and quality of frozen seafood. It is also used as thickening agents for desserts such as puddings.
Tetrapotassium Pyrophosphate is used as a spray adjuvant that aids farmers in improving absorption of herbicides by crops to stimulate better growth results.
Tetrapotassium Pyrophosphate is used as chelating and oral care agent in products, such as toothpaste and mouthwash, that prevents deposition of calcium and magnesium onto teeth.
Tetrapotassium Pyrophosphate is used in the manufacturing of detergent and soap due to its emulsifying and water softener properties.
