A NEW APPROACH OF EGYPTIAN CALCIUM CARBONATE UTILIZATION AS INGREDIENTS OF TOOTHPASTE MANUFACTURE
Nowadays, the calcium carbonate material is used on a wide scale as an effective dietary calcium supplement, antacid, phosphate binder, and base material for medicine tablets such as baking powder and toothpaste components. This study introduces a contribution and characterization of the Beni Khaled calcium carbonate for toothpaste pharmaceutical ingredients. Calcium carbonate samples were ground to very fine grain size ranging from 5 20 um to be used as an abrasive ingredient of toothpaste components by 25 55 % as per international standard. The testing techniques include measuring of physical, chemical and biological properties; XRF, XRD, water absorption, matter soluble in water, and biological study of harmful bacteria types which disappeared with the heating of CaCO3 powder up to 121oC.
