White powder; Melting point 622°C; Easily soluble in water; It has got salient chelating capacity to ions of Ca and Mg etc. 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. It has different bulk density, i.e. low density 0.35-0.5g/cm3, medium density 0.51-0.65g/cm3 and high density 0.66-0.9g/cm3. This product has two crystalline forms, namely Type I (high temperature type) and Type II (low temperature type). The chemical properties of the two types are the same, and the difference between them lies in the thermostability, hygroscopicity, solubility and hydration heat when dissolving .

1. Used as one of the main auxiliaries for synthetic 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 foodstuff industry it is used as quality improver in the process of canned food, fruit juice drinks, foodstuffs from milk or soybeans. It may tender the meat in canned ham and soften the skin of horse bean in canned horse bean. It may also serves as a softener or densifier in foodstuff industry.

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 charged chelating agent, TPP5− binds to dications tightly and prevents them from interfering with the sulfonate detergent.
Food
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 "GRAS(Generally Recognized As Safe)."
Other
Other uses (hundreds of thousands of tons/year) include ceramics (decrease the viscosity of glazes up to a certain limit), leather tanning (as masking agent and synthetic tanning agent - SYNTAN), anticaking agents, setting retarders, flame retardants, paper, anticorrosion pigments, textiles, rubber manufacture, fermentation, antifreeze."TPP is used as a polyanion crosslinker in polysaccharide based drug delivery.Toothpaste.
