calcium hydrogen phosphate dihydrate News & Market Updates

Calcium hydrogen phosphate dihydrate (DCPD) serves dual roles: as a mild abrasive in premium toothpaste and as a key feed phosphate additive. In oral care, its Mohs hardness of 2-2.5 makes it gentler on enamel than silica (hardness 7), and it supports enamel remineralization…
