Sodium Hexameta Phosphate (SHMP-TG) is used as a surfactant, emulsifier, suspending agent, dispersing agent,is a clean, non-toxic phosphate, that is widely used in the food industry and the chemical industry. It can be used as a chelating reagent for metal ions, an adhesive, and a swelling reagent. SHMP 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.
