Tetrasodium pyrophosphate

Tetrasodium Pyrophosphate (TSPP) | High-Purity Na4P2O7 for Industrial & Food Applications

Product Description

Alias: Sodium pyrophosphate for food / Tetrasodium pyrophosphate/TSPP food grade

Molecular formula: Na4P2O7, Na4P2O7•10H2O

Physicochemical properties: White powder or crystal. Melting point 880ºC. Density 2.534g/cm3. Soluble in water and insoluble in alcohol. It's aqueous solution is alkaline and stable below 70ºC, hydrolyzes into sodium hydrogen phosphate after boiling. Can form complex with alkaline earth metal ion, liable to deliquesce.

Tetrasodium Pyrophosphate (TSPP), with the chemical formula Na4P2O7, is a versatile inorganic compound widely recognized for its emulsifying, buffering, and chelating properties. Available in both anhydrous and decahydrate forms, our TSPP meets stringent industrial-grade and food-grade standards (JECFA INS No. 450(iii)), making it ideal for applications ranging from water treatment to food processing.
