Chemical Structure:

Sodium hexametaphosphate is a hexamer of composition. It is typically a mixture of polymeric metaphosphates, of which the hexamer is one, and is usually the compound referred to by this name. It is more correctly termed sodium polymetaphosphate. Sodium hexametaphosphate is prepared by melting monosodium orthophosphate, followed by rapid cooling. Sodium hexametaphosphate hydrolyzes in aqueous solution, particularly under acidic conditions, to sodium trimetaphosphate and sodium orthophosphate.
Sodium hexametaphosphate is used as a sequestrants (metal binders), stabiliser and emulsifiers. It is also used to retain water during processing and storage. It is also a whitening ingredient in some whitening toothpastes.
