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.
The alkaline phosphates offer detergency activity in combination with the properties of sequestration, dispersion and buffering ability. STPP is used in water softening, industrial cleaners, food uses, detergent, emulsifier of oil and grease, peptizing agent, deflocculating agent in oil well, sequester in cotton boiling.

What is STPP? 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. Specifications of STPP Body Chemical Analysis Percentage (%) Physical Properties Test Result Loss 43.07 ± 5 Physical State Solid SiO2 26.00 ± 5 Colour White Na2O 29.83 ± 5 Odor Odorless F 1.1 ± 5 Whiteness 90 PH of 1.0% 12.50 Melting Point 72.2 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
