| Title of Invention | PRECIPITATED CALCIUM CARBONATE |
|---|---|
| Abstract | An abrasive precipitated calcium carbonate is provided that provides excellent cleaning properties without being excessively abrasive or damaging to gums or tooth surfaces. The abrasive, precipitated calcium carbonate has a primary particle size of about 1 µm to about 4 µm, and an aggregate size of about 3 µm to about 10 µm. Also disclosed is a method for forming calcium carbonate comprising the steps of providing a reaction medium; introducing carbon dioxide and the calcium hydroxide slurry simultaneously into a reaction medium to form calcium carbonate while maintaining constant pH during calcium carbonate precipitation; and optionally drying the calcium carbonate slurry to form a dried calcium carbonate product. Also disclosed is a dentifrice containing the aforementioned abrasive, precipitated calcium, and one or more ingredients selected from the group consisting of humectants, thickening agents, binders, gums, stabilizing agents, antibacterial agents, fluorides, sweeteners, and surfactants. |
