STPP or sodium triphosphate 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. Sodium tripolyphosphate is produced by heating a stoichiometric mixture of disodium phosphate, Na2HPO4, and monosodium phosphate, NaH2PO4, under carefully controlled conditions.

Application In Food:
The uses of stpp include using it as a preservative. Sodium Tripolyphosphate STPP can be used to preserve foods such as red meats, poultry, and seafood, helping them to retain their tenderness and moisture. Pet food and animal feed have been known to be treated with Sodium tripolyphosphate stpp , serving the same general purpose as it does in human food.
In Tech:
The majority of STPP Sodium tripolyphosphate is consumed as a component of commercial detergents.
Other uses include "ceramics (increase viscosity of the glazes upto a certain limit), leather tanning (as masking agent and synthetic tanning agent - SYNTAN), anticaking, setting retarders, flame retardants, paper, anticorrosion pigments, textiles, rubber manufacture, fermentation, antifreeze."STPP is used as a polyanion crosslinker in polysaccharide based drug delivery.
