Disodium Phosphate, Purity : 98% min for Industrial

Disodium phosphate (DSP), or sodium hydrogenphosphate, 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.
Details : Disodium phosphate is a food additive that combines the minerals phosphate, or phosphorus, and sodium. Phosphate salts are also sometimes used as medicine, and they're generally regarded as safe by the U.S. Food and Drug Administration. People with certain health conditions requiring low phosphorus intakes, however, may want to minimize the amount of disodium phosphate they consume. It can be used in water treatment and as a flame retardant. In medicine, it may help lower high blood levels of calcium or increase low blood levels of phosphate. It may also be helpful for limiting some types of kidney stones, but the evidence for this is still preliminary, according to MedlinePlus.
