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.

Use of ozone to control bioburden in precipitated calcium carbonate slurry (PCC)

The present invention provides the use of composition a as an antimicrobial agent, wherein the composition comprises anethole, an anionic surfactant, and an orally acceptable vehicle, wherein the composition is free from additional flavor ingredients; and a method of increasing the resistance of a composition to microbial attack, the method comprising formulating the composition so as to comprise anethole, an anionic surfactant, and an orally acceptable vehicle, wherein the composition is free from additional flavor ingredients. The present invention also provides a method of making an oral care composition.

Increasing micro-robustness

Biguanide-preserved precipitated calcium carbonate oral care compositions and methods of manufacture thereof are disclosed.
