Sodium Polymetaphosphate


Chemical information

E452 (sodium polyphosphates); Polimetafosfato de sodio.
CAS — 50813-16-6.
NOTE. Although Sodium hexametaphosphate has been used as a synonym for the polymetaphosphate, the latter also exists in much higher degrees of polymerisation.


Sodium polymetaphosphate has been used as a 5% dusting powder in hyperhidrosis and bromhidrosis, and as a prophylactic against athlete’s foot. Sodium polymetaphosphate combines with calcium and magnesium ions to form complex soluble compounds and is used as a water softener.
