'''Sodium triphosphate''' (STP), also '''sodium tripolyphosphate''' (STPP), or '''tripolyphosphate''' (TPP),<ref name="Danish EPA 615 2001">[http://www2.mst.dk/udgiv/publications/2001/87-7944-596-9/html/kap07_eng.htm#7.1.1 Complexing agents], [http://www2.mst.dk/udgiv/publications/2001/87-7944-596-9/html/default_eng.htm Environmental and Health Assessment of Substances in Household Detergents and Cosmetic Detergent Products], [http://www.mst.dk/English/ Danish Environmental Protection Agency] {{Webarchive|url=https://web.archive.org/web/20170824063106/http://mst.dk/English/ |date=2017-08-24 }}, Accessed 2008-07-15</ref>) is an [[inorganic compound]] with formula Na<sub>5</sub>P<sub>3</sub>O<sub>10</sub>. It is the [[sodium]] salt of the [[polyphosphate]] penta-anion, which is the [[conjugate (acid-base theory)|conjugate base]] of [[triphosphoric acid]]. It is produced on a large scale as a component of many domestic and industrial products, especially detergents. Environmental problems associated with [[eutrophication]] are attributed to its widespread use.<ref name=GE/>
