Use
Shmp is used as a sequestrant and has applications within a wide variety of industries, including as a food additive in which it is used under the e number e452i. Sodium carbonate is sometimes added to shmp to raise the phto 8.0–8.6, which produces a number of shmp products used for water softening and detergents.
A significant use for sodium hexametaphosphate is as a deflocculant in the production of clay-based ceramicparticles.[3][4][5][6] it is also used as a dispersing agent to break down clay and other soil types.[7]
It is used as an active ingredient in toothpastes as an anti-staining and tartar prevention ingredient.[8]
Food additive
Artificial maple syrup, canned milk, cheese powders and dips, imitation cheese, whipped topping, packaged egg whites, roast beef, fish fillets, fruit jelly, frozen desserts, salad dressing, herring, breakfast cereal, ice cream, beer, and bottled beverages, among other foods, can contain sodium hexametaphosphate.
Technical specifications available on request. Buyer or buyer's representative to fill in a "requirements form" on the basis on which a "SCO" will be given. Price is dependent upon quantity.
As an effective dispersion agent for suspensions of coatings, kaolin, magnesium oxide, calcium carbonate and drilling mud, etc. As an oil contamination resistance agent in paper production 94.0% min.
It is white powder, it has salient chelating capacity to ions of Ca, Mg etc; it can soften the hard water to make suspension become into the clear solution; it has weak alkalinity but no corrosiveness. it is a surfactant which has outstanding emulsification for lubricants and fat.it has different bulk density.
It is used as one of the main auxiliaries agent for synthetic detergent, synergist for soap, tanning agent for making leather, softener for water industry, an effective dispersion agent for suspension treatment of painting, kaolin, magnesium oxide, calcium carbonate and drilling mud etc; resistance agent of the oil contamination in paper production.

Chemical formula:na5p3o10
Appearance:white powder
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 charged chelating 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.[5] 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 (decrease the viscosity of 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."[5] tpp is used as a polyanion crosslinker in polysaccharide based drug delivery.
Sodium Tripolyphosphate (STPP), the sodium salt of polyphosphate penta-anion, also known as pentasodium tripolyphosphate or sodium triphosphate is an inorgaic compound with formula Na5P3O10.It is the sodium salt of the poly phosphate penta-an, it is thr conjugate base of triphosphoric acid.

How is STPP Used in Ceramic Sector?
Sodium Tri Polyphosphate (STPP) is generally employed as a dispersing agent in ceramic processing and could be a low-cost plasticizer for ceramic based materials. The effect was inverted in the case of higher STPP concentrations, for which faster setting of ceramic product can be observed.
What are the Applications of STPP in others?
In household cleaning products, sodium tripolyphosphate is used most widely as builder. In conjunction with surfactants, it allows detergents to perform efficiently in all washing conditions. It is widely used in laundry detergents, dishwasher detergents, industrial and institutional detergents
