sodium hexametaphosphate CAS#10124-56-8
The sodium polyphosphates class consists of several amorphous, water soluble polyphosphates composed of linear chains of metaphosphate units, (NaPO3)x where x ≥ 2, terminated by Na2PO4- groups. They are usually identified by their Na2O/ P2O5 ratio or their P2O5 content. The Na2O/P2O5 ratios vary from about 1.3 for sodium tetrapolyphosphate, where x = approximately 4; through about 1.1 for Graham’s salt, commonly called sodium hexametaphosphate, where x = 13 to 18; to about 1.0 for the higher molecular weight sodium polyphosphates, where x = 20 to 100 or more. The pH of their solution varies from about 3 to 9. For additional details of description, refer to Burdock (1997).

Product Application of sodium hexametaphosphate CAS#10124-56-8
Sodium Hexametaphosphate is a sequestrant and moisture binder that is very soluble in water but dissolves slowly. solutions have a ph of 7.0. it permits peanuts to be salted in the shell by making it possible for the salt brine to penetrate the peanuts. in canned peas and lima beans, it functions as a tenderizer when added to the water used to soak or scald the vegetables prior to canning. it improves whipping properties in whipping proteins. it functions as a seques- trant for calcium and magnesium, having the best sequestering power of all the phosphates. it prevents gel formation in sterilized milk. it is also termed sodium metaphosphate and graham’s salt.
