Sodium triphosphate (STP), also sodium tripolyphosphate (STPP), or tripolyphosphate (TPP), is an inorganic compoundwith 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.

Food applications:-
Mainly used as additive agent, pH adjusting agent, fermenting agent, and nourishment, etc.
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.
Other uses:-
Other uses (hundreds of thousands of tons/year) include ceramics (increase viscosity of the glazes up to 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."
TPP is used as a polyanion crosslinker in polysaccharide based drug delivery.
