Tetrasodium Pyrophosphate Introduction
Tetrasodium pyrophosphate, also called TSPP, is an inorganic compound with the formula Na4P2O7. As a salt, it is a white, water-soluble solid. It is composed of pyrophosphate anion and sodium ions. Toxicity is approximately twice that of table salt when ingested orally. Also known is the decahydrate Na4P2O7 ·10(H2O).
