Dicalcium Phosphate
What is Dicalcium Phosphate?
Dicalcium phosphate is an inorganic calcium phosphate compound, typically appearing as a fine, white, odorless powder derived from reacting calcium hydroxide with phosphoric acid. Insoluble in water, it occurs naturally in minerals like apatite and biological structures such as bones and teeth. In cosmetics, it finds primary application in oral care products like toothpaste, where it acts as a mild abrasive for surface polishing. Additionally, it serves as an opacifying agent to reduce transparency and create a smooth, uniform visual effect in formulations. As a bulking agent, it adds volume and structure, enhancing product spreadability and feel without altering key actives. Its chemical stability ensures consistent performance in wet environments, supporting gentle mechanical exfoliation in select skincare items while maintaining biocompatibility for repeated use.
