It is a salt composed of pyrophosphate and sodium ions. Toxicity is approximately twice that of table salt when ingested orally.

Sodium Acid Pyrophosphate is a synthetic, edible phosphoric salt. It is a white mass or free-flowing powder that is used in self-rising and prepared baked goods to control the pH amounts in food.

Detaills : Sodium acid pyrophosphate finds applications in oil drilling and detergent. It also acts as an excellent chemical stabiliser.

sodium hexametaphosphate  is used as a sequestrant and has applications within a wide variety of industries, including as a food additive in which it is used under the E number E452i.Sodium carbonate is sometimes added to SHMP to raise the pH to 8.0–8.6, which produces a number of SHMP products used for water softening and detergents.
