Properties

Sodium acid pyrophosphate, or disodium pyrophosphate, is an edible phosphoric salt that helps create leavening used for baking, such as baking powder, and prevents food discoloration, such as in raw potatoes.

In its bulk state, such as at the manufacturing laboratory, the acidic nature of sodium acid pyrophosphate may be very hazardous upon skin or eye contact, inhalation or ingestion, causing severe inflammation.
