Disodium Phosphate (Anhydrous BP)

Listing ID #819405

Disodium Phosphate (Anhydrous BP) is the inorganic compound with the formula Na₂HPO₄. It is one of several sodium phosphates. The salt is known in anhydrous form as well as forms with 2, 7, 8, and 12 hydrates. All are water-soluble white powders; the anhydrous salt being hygroscopic.
Disodium Phosphate is used primarily as a food additive for stabilization, emulsification and phosphate fortification.
Disodium Phosphate is an acid salt. Acid salts serve as buffers, controlling the acidity or alkalinity of an environment. In a buffer system, the pH of the solution changes little upon the addition of a small amount of strong acid or base. In this capacity, acid salts act both as an acid or a base, depending upon the other chemicals in the environment.
Disodium Phosphate is in various industrial cleaning products, working as a disinfectant, fungicide and sanitizer. It can also be used in medications designed to eliminate retained fluid.
Disodium Phosphate prevents or slows down the growth of bacteria and other microorganisms on foods.
