STPP, sodium tripolyphosphate food grade is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid. Sodium tripolyphosphate is produced by heating a stoichiometric mixture of disodium phosphate, Na2HPO4, and monosodium phosphate, NaH2PO4, under carefully controlled conditions.

1)In detergents
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 of Mg2+ and Ca2+), detergents are
deactivated. Being a highly chargedchelating agent, TPP5- binds to dications
tightly and prevents them from interfering with the sulfonate detergent.
2)Food applications
STPP is a preservative for seafood, meats, poultry, and animal feeds.It is common
in food production as E number E451. In foods, STPP is used as an emulsifier and
to retain moisture. Many governments regulate the quantities allowed in foods,
as it can substantially increase the sale weight of seafood in particular. The UnitedStates Food and Drug Administration lists STPP as "generally recognized as safe."
