Calcium Phosphate Dibasic CAS#7757-93-9
Dibasic calcium phosphate is synthesized through the reaction of phosphoric acid with calcium chloride and sodium hydroxide, though calcium carbonate can also be used as a substitute for calcium chloride and sodium hydroxide.
Anhydrous dibasic calcium phosphate is generally considered to be low in toxicity and non-irritating, making it widely suitable for use in oral pharmaceutical products and food applications.
Functional Uses in Foods: Acts as a leavening agent, dough conditioner, nutrient, dietary supplement, and yeast food.
Dibasic calcium phosphate can be found in anhydrous form or with two molecules of water of hydration. It appears as a white, odorless, tasteless powder that is stable in air. It is practically insoluble in water, insoluble in alcohol, but readily soluble in dilute hydrochloric and nitric acids.
