SODIUM TRI POLY PHOSPHATE

Sodium triphosphate (STP), also sodium tripolyphosphate (STPP), or tripolyphosphate (TPP) is an inorganic compound with the 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 widespread use.
