Usage areas of Sodium hexametaphosphate
Sodium hexametaphosphate (SHMP) is a hexamer of the compound (NaPO3) 6. Commercial sodium hexametaphosphate is typically a mixture of polymeric metaphosphates of which the hexamer is a and is the compound often referred to by this name. More precisely, it is called sodium polymetasphate.
- SHMP is used as a sequestrant and has applications in a wide variety of industries, including as a food additive used under E number E452i. Sometimes sodium carbonate is 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.
- An important use for sodium hexametaphosphate is as a dissolving agent in the manufacture of clay-based ceramic particles.
- It is also used as a dispersant to break up clay and other soil types for soil texture assessment.
- It is used as an anti-staining and anti-tartar ingredient as an active ingredient in toothpastes.
- It takes the hardness of the water. By softening the water, it provides better wetting of the dust in the environment.
