CALCIUM CARBONATE
Safety grade: A
Calcium carbonate is a white, chalky powder commonly found in nature as limestone and seashells. It's the same ingredient used in antacids and blackboard chalk.
This ingredient is used in cosmetics as a gentle abrasive for scrubbing and cleansing, a buffering agent to balance pH, a thickener to add body to products, and an opacifying agent to create a smooth, matte appearance, making it especially useful in toothpastes and exfoliating formulations.
