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.
White powder or granular; Easily soluble in water; It has got the salient chelating capacity to Ca and Mg ions. and can soften hard water to make suspension solution become into clear solution; It has got weak alkalinity but no corrosiveness. It is a surfactant, and has got outstanding emulsification to lubricants and fat.
1. Used in detergent, synergist for soap;
2. Water softener; tanning agent for leather making, auxiliary for dyeing;
3. As an effective dispersion agent for suspension solutions of coatings, kaolin, magnesium oxide, calcium carbonate and drilling mud, etc.;
4. As an oil contamination resistance agent in paper production.
5. In the foodstuff industry it is used as a quality improver in the process of canned food, fruit juice drinks, foodstuffs from milk or soybeans.
6.It may tender the meat in canned ham and soften the skin of horse bean in canned horse bean.
7.It may also serves as a softener or densifier in foodstuff industry.
In Food:
The uses of step 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 stop, 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 up to a certain limit), leather tanning (as masking agent and synthetic tanning agent - SYNTAX), 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
