Sodium hexametaphosphate is a salt of composition Na₆[(PO₃)₆]. Sodium hexametaphosphate of commerce is typically a mixture of metaphosphates, of which the hexamer is one, and is usually the compound referred to by this name. Such a mixture is more correctly termed sodium polymetaphosphate.

 Formula (NaPO₃)_{6 =} 611.77 g/mol

Sodium hexametaphosphate (SHMP) is a clean, non-toxic phosphate that is widely used in the food industry and the chemical industry [27,28]. It can be used as a chelating reagent for metal ions, an adhesive, and a swelling reagent

 CAS number - There is some debate. Merck use 10124-56-8 as we have traditionally used, but Sigma Aldrich use 68915-31-1 . We are not exactly sure why there is this discrepancy.
