Product Description

Product description

Sodium triphosphate (STP, STPP or sodium tripolyphosphate or TPP, ) is an inorganic compound with 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 widespreaduse.

Preparation and properties
Sodium tripolyphosphate is produced by heating a stoichiometric mixture of disodium phosphate, Na2HPO4, and monosodium phosphate,
NaH2PO4, under carefully controlled conditions.

2 Na2HPO4 + NaH2PO4 Na5P3O10 + 2 H2O
In this way, approximately 2 million tons are produced annually.

STPP is a colourless salt, which exists both in anhydrous form and as the hexahydrate. The anion can be described as the
pentanionic chain [O3POP(O)2OPO3]5-. Many related di-, tri-, and polyphosphates are known including the cyclic triphosphate
P3O93-. It binds strongly to metal cations as both a bidentate and tridentate chelating agent.

Uses
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.

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 United
States Food and Drug Administration lists STPP as "generally recognized as safe. ".

Other uses
Other uses (hundreds of thousands of tons/year) include "ceramics, leather
Tanning(as masking agent and synthetic tanning agent - SYNTAN), anticaking,
Setting retarders, flame retardants, paper, anticorrosion pigments, textiles,
Rubber manufacture, fermentation, antifreeze.
