Editing Sodium triphosphate (section)

==Uses==

===Detergents===
The majority of STPP is consumed as a component of commercial [[detergent]]s. It serves as a "builder", industrial jargon for a water softener. In hard water (water that contains high concentrations of Mg<sup>2+</sup> and Ca<sup>2+</sup>), detergents are deactivated. Being a highly charged [[chelating agent]], TPP<sup>5−</sup> binds to [[dications]] tightly and prevents them from interfering with the sulfonate detergent.<ref name=Ullmann>{{cite book |doi=10.1002/14356007.a19_465.pub3 |chapter=Phosphoric Acid and Phosphates |title=Ullmann's Encyclopedia of Industrial Chemistry |year=2008 |last1=Schrödter |first1=Klaus |last2=Bettermann |first2=Gerhard |last3=Staffel |first3=Thomas |last4=Wahl |first4=Friedrich |last5=Klein |first5=Thomas |last6=Hofmann |first6=Thomas |isbn=978-3527306732 |s2cid=94458523 }}</ref>

===Food===
STPP is a [[preservative]] for seafood, meats, poultry, and [[compound feed|animal feed]]s.<ref name=Ullmann/> 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]].<ref>{{cite web|url=https://www.hfpappexternal.fda.gov/scripts/fdcc/index.cfm?set=FoodSubstances&id=SODIUMTRIPOLYPHOSPHATE|title=Substances Added to Food (Formerly EAFUS)}}</ref>

===Other===
Other uses (hundreds of thousands of tons/year) include [[ceramic engineering|ceramics]] (decrease the viscosity of glazes up to a certain limit), [[leather tanning]] (as masking agent and synthetic tanning agent - SYNTAN), [[anticaking agent]]s, setting retarders, [[flame retardant]]s, [[paper]], [[anticorrosion compound|anticorrosion]] [[pigments]], [[textiles]], [[rubber]] manufacture, [[fermentation (biochemistry)|fermentation]], [[antifreeze]]."<ref name=Ullmann/> TPP is used as a polyanion crosslinker in polysaccharide based [[drug delivery]].<ref>{{cite journal |last1=Calvo |first1=P. |last2=Remuñán-López |first2=C. |last3=Vila-Jato |first3=J.
