Tetrasodium pyrophosphate

Tetrasodium pyrophosphate (TSPP) is a white, crystalline, odorless solid that is highly soluble in water and non-volatile; it decomposes before melting, typically above 600 °C. It is an inorganic sodium salt of pyrophosphoric acid and belongs to the class of condensed phosphates. TSPP is widely used as a sequestrant, emulsifier, and buffering agent in food processing (e.g., dairy and meat products), detergent formulations, and water treatment. It serves as a key intermediate in the production of other phosphates and is employed in ceramic glazes, metal surface treatment, and textile processing. Typical application areas include food additives, household and industrial cleaners, ceramics, and metallurgical processing.

Tetrasodium pyrophosphate is a white crystalline powder or colourless crystals with the formula Na4P2O7. It contains the pyrophosphate ion and sodium cation. Toxicity is approximately twice that of table salt when ingested orally. There is also a hydrated form, Na4P2O7.10H2O.
