description The chemical compound sodium tripolyphosphate, or STPP for short, has the formula Na5P3O10. It is an inorganic salt made up of the tripolyphosphate anion (P3O105-) and sodium cations (Na+). The capacity of STPP to maintain pH levels, speed up soil degradation, and sequester minerals in hard water to increase surfactant efficacy are just a few of its many benefits. It is created by neutralizing phosphoric acid, which can be made using thermal or wet methods. To obtain a high yield of the intended final product, sodium tripolyphosphate is made up of one unit of monosodium orthophosphate and two units of disodium orthophosphate, which are thoroughly mixed.
