Product Description

Sodium Pyrophosphate:
Molecular Formular: Na4P2O7       Molecular weight: **0.*3
Tetrasodium pyrophosphate, also called sodium pyrophosphate, tetrasodium phosphate or TSPP,contains the pyrophosphate ion and sodium cation. Its density is 2.*3. When it is heated to **0 Degree, it will loss two molecular of crystal water; when **0 Degree, it will loss all of their water crystallization.

Application: 1)Sodium pyrophosphate is used as a buffering agent, an emulsifier, a dispersing agent, and a thickening agent, and is often used as a food additive. Common foods containing sodium pyrophosphate include chicken nuggets, marshmallows, pudding, crab meat, imitation crab, canned tuna, and soy-based meat alternatives and cat foods and cat treats where it is used as a palatability enhancer. It is the active ingredient in Bakewell, the substitute for baking powder\'s acid component marketed during shortages in World War II. It is also used in some common baking powders.

                   2). In toothpaste and dental floss, sodium pyrophosphate acts as a tartar control agent, serving to remove calcium and magnesium from saliva and thus preventing them from being deposited on teeth.

                   3). Sodium pyrophosphate is sometimes used in household detergents to prevent similar deposition on clothing, but due to its phosphate content it causes eutrophication of water, promoting algae growth.
