We are one of the leading manufacturer, supplier, dealer, wholesaler and stockists of Tripolyphosphate in India. Sodium Tripolyphosphate 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. STPP is a colourless salt, which exists both in anhydrous form and as the hexahydrate.
