Disodium diphosphate sample

Disodium Diphosphate is a white crystalline powder, soluble in water.
Disodium is a buffering and chelating agent used in canned seafood, as a scald agent in poultry and pork, as a sequesterant in potato products, and is used to aid leavening in baked goods. In leather treatment it can be used to remove iron stains on hides during processing.

It can stabilize hydrogen peroxide solutions against oxidation. It can be used for cleaning with sulfamic acid in some dairy applications. In petroleum production, it can be used as a dispersant in oil well drilling muds. Disodium pyrophosphate is also found in hash browns (frozen) to keep the color of the potatoes from fading.
