Appearance: white odorless crystalline powder.
Solubility: soluble in water but insoluble in organic solvent.
Characteristic:
Density 2.484(20ºC); It has got strong hygroscopicity and can absorb humidity from the air to become into pasty form; It may form soluble chelates with ions of Ca, Ba, Mg, Cu, Fe etc. and is a good water treatment chemical.

In food industry it used as an additive, nourishing agent, quality improver, pH regulator, metal ions chelating agent, adhesive and leavening agent etc.![CAS No 10124-56-8 / 68915-31-1 [Food Grade] (SHMP) Sodium Hexameta Phosphate 68%](http://image.made-in-china.com/226f3j00zyclIUmtYpbr/CAS-No-10124-56-8-68915-31-1-Food-Grade-SHMP-Sodium-Hexameta-Phosphate-68-.jpg)
We normally list 2 years as the shelf life in our COA, the real shelf life is actually much longer than 2 years if it's stocked in good condition (bags are sealed enough, away from direct sun-light, moisture and other incompatible chemical materials)
