Abstract
An oral care composition containing a source of stannous ions, a source of fluoride ions and an insoluble source of zinc ions, such as zinc oxide. The composition contains an amount of citric acid sufficient to increase the level of soluble zinc ions.
Claims21

- (a) an orally acceptable vehicle;
- (b) a source of fluoride ions;
- (c) a source of stannous ions;
- (d) an insoluble source of zinc ions;
- (e) a buffering system comprising citric acid wherein the amount of citric acid is at least 1% by weight of the composition, and wherein the composition has a total water content of less than 15% by weight, based on the weight of the composition.
