Product Description
High quality water retaining agent STPP food grade 

Sodium triphosphate (STP, STPP or sodium tripolyphosphate or TPP) is an inorganic compound with formula Na5P3O10. It is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid. It is produced on a large scale as a component of many domestic and industrial products, especially detergents. Environmental problems associated with eutrophication are attributed to its widespreaduse. 

High quality water retaining agent STPP food grade 

Sodium tripolyphosphate STPP is produced by heating a stoichiometric mixture of disodium phosphate, Na2HPO4, and monosodium phosphate, NaH2PO4, under carefully controlled conditions. 

2 Na2HPO4 + NaH2PO4 Na5P3O10 + 2 H2O
In this way, approximately 2 million tons are produced annually. 

High quality water retaining agent STPP food grade 

STPP is a colourless salt, which exists both in anhydrous form and as the hexahydrate. The anion can be described as the pentanionic chain [O3POP(O)2OPO3]5-. Many related di-, tri-, and polyphosphates are known including the cyclic triphosphate P3O93-. It binds strongly to metal cations as both a bidentate and tridentate chelating agent.
