Description: 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.
Applicaiton: 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.
