Dicalcium phosphate, likewise referred to as dibasic calcium phosphate or calcium monohydrogen phosphate, is a type of calcium phosphate that is dibasic. It is usually discovered as the dihydrate, with the chemical formula of CaHPO4 – 2H2O, but it can be thermally converted to the anhydrous type, which has actually been referred to by the abbreviation ‘DPCA’. It is virtually insoluble in water, with a solubility of 0.02 g per 100 mL at 25 ° C. It contains about 29.5 percent calcium in its anhydrous type. On contact with water, it converts to hydroxyapatite, which is insoluble solid, and phosphoric acid.
Dicalcium phosphate is generally utilized as a dietary supplement in ready breakfast cereals, pet deals with, enriched flour, and noodle products. It is likewise used as a tableting representative in some pharmaceutical preparations, consisting of some products implied to eliminate body odor. Dicalcium phosphate is also discovered in some dietary calcium supplements (e.g. Bonexcin). It is used in poultry feed. It is likewise used in some toothpastes as a tartar control representative.
