1 Product Brief Introduction
CAS: 7758-29-4
EINECS: 231-838-7
Sodium triphosphate (STP, sometimes STPP or sodium tripolyphosphate or TPP,[1]) 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 widespread use.
