Sodium Tripolyphosphate

Sodium Tripolyphosphate, also Food Grade Stpp, or Stpp Detergent Powder,is an inorganic compound with formula Na5P3O10. Stpp Sodium Tripolyphosphate 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 in Water Treatment.

The majority of STPP is consumed as a component of commercial detergents. It serves as a "builder," industrial jargon for a water softener. In hard water (water that contains high concentrations Ethylene-Vinyl Acetate of Mg2+ and Ca2+), detergents are deactivated. Being a highly charged chelating agent, TPP5− binds to dications tightly and prevents them from interfering with the sulfonate detergent.

Because it is very water-soluble, STPP is not significantly Pvc Resin removed by waste water treatment. STPP hydrolyses to phosphate, which is assimilated into the natural phosphorus cycle. Detergents containing phosphorus contribute to the eutrophication of many fresh waters.
