Abstract
The present disclosure is directed to a method for reducing bacteria in a precipitated calcium carbonate (CaCO) slurry, the method including: adding water to calcium oxide (CaO) to form Ca(OH); treating the Ca(OH)with COgas to form a slurry including precipitated CaCO; neutralizing the slurry; and exposing the slurry that was neutralized to ozone in an amount sufficient to reduce bacteria in the precipitated calcium carbonate slurry. Oral care compositions including the precipitated calcium carbonate of the disclosed process are also described.
