Brief:
Sodium hexametaphosphate, also known as its abbreviation SHMP, is a hexamer of sodium phosphate (NaPO3)6. It is a water-soluble polyphosphate that consists of chains of six repeating phosphate units.SHMP is commonly used in dairy products, sausage, seafood, meat processing, toothpaste.|

A partial sodium phosphate polymer, transparent glass flake or white powder crystal. The hygroscopicity is strong; after the moisture absorption becomes sticky, is easy to be moist in the air, is soluble in the water, in the water solubility is bigger, but the dissolution speed is slow; the aqueous solution assumes the acidic reaction. Easy hydrolysis or phosphite. For some metal ions (calcium, magnesium) have the ability to produce or dissolve complex, it can be used to soften water, and lead, silver, barium salt can also be complex.
