Abstract
Disclosed herein are improved oral care formulations comprising precipitated calcium carbonate (PCC) and synergistic preservative combinations selected. Methods of making and using the compositions are also provided.
Claims11
An oral care composition comprising:
- precipitated calcium carbonate (PCC);
- pentylene glycol in an amount of about 0.1 wt. % to about 5.0 wt. %, based on the weight of the composition;
- caprylyl glycol in an amount of about 0.1% to about 1.0%, based on the weight of the composition;
- benzyl alcohol in an amount of about 0.1% to about 1.0%, based on the weight of the composition;
- and
- optionally, xylitol
- wherein the composition achieves a log reduction in microbial bioburden of greater than 5.0 after 4 hours when challenged with Halomonas bacterial pool assay in a PCC base comprising a surfactant.
4 more elements
An oral care composition comprising:
- precipitated calcium carbonate (PCC);
- and
- a preservative combination consisting essentially of pentylene glycol in an amount of about 0.1 wt % to 5.0 wt % and caprylyl glycol in an amount of about 0.1 wt % to 1.0 wt % wherein the composition achieves a log reduction in microbial bioburden of greater than 6 after 24 hours when challenged with bacterial pool assay in a surfactant-free PCC base.
