The present invention relates to oral care compositions comprising stannous ions, a mint-type flavor oil, a protectant component that prevents generation of off odor and off taste in the composition, and orally acceptable carriers. The mint-type oils include peppermint, spearmint and corn mint. Suitable protectant components include copper salts and carbonyl compounds such as ascorbic acid; cis-jasmone; 2,5-dimethyl-4-hydroxy-3(2H)-furanone; 5-ethyl-3-hydroxy-4-methyl-2(5H)-furanone; vanillin; ethyl vanillin; anisaldehyde; 3,4-methylenedioxybenzaldehyde; 3,4-dimethoxybenzaldehyde; 4-hydroxybenzaldehyde; 2-methyoxybenzaldehyde; 4-methoxybenzaldehyde; benzaldehyde; cinnamaldehyde (3-phenyl-2-propenal); hexyl cinnamaldehyde; α-methyl cinnamaldehyde; ortho-methoxy cinnamaldehyde; α-amyl cinnamaldehyde; and combinations thereof. The oral care composition may be a dentifrice.

The present invention relates to aesthetically pleasing oral care formulations that contain flavor compositions and stannous ions.
Stannous ions are desired to be used in oral compositions. Stannous ions, commonly supplied from stannous fluoride and other stannous salts, are used to provide anti-plaque, anti-gingivitis, and improve breath and sensitivity. However, formulating with stannous ions has proven to be challenging as formulations containing the stannous ions have been known to not be aesthetically pleasing. Stannous ions can provide a malodor when used in combination with certain oral care flavoring compounds. It remains desirable to provide oral care compositions that provide efficacious delivery of stannous ions with an aesthetically pleasing flavor. None of the existing art provides all of the aesthetic advantages and benefits of the present invention.
The present invention relates to oral care compositions comprising stannous ions, a mint-type flavor oil, a protectant component that prevents generation of malodor and off taste in the composition, and orally acceptable carriers. The mint-type oil includes peppermint, spearmint and corn mint. Suitable protectant components include carbonyl compounds such as ascorbic acid; cis-jasmone; 2,5-dimethyl-4-hydroxy-3(2H)-furanone; 5-ethyl-3-hydroxy-4-methyl-2(5H)-furanone; vanillin; ethyl vanillin; anisaldehyde; 3,4-methylenedioxybenzaldehyde; 3,4-dimethoxybenzaldehyde; 4-hydroxybenzaldehyde; 2-methoxybenzaldehyde; benzaldehyde; cinnamaldehyde; hexyl cinnamaldehyde; α-methyl cinnamaldehyde; ortho-methoxy cinnamaldehyde; α-amyl cinnamaldehyde; and combinations thereof.
While the specification concludes with claims particularly pointing out and distinctly claiming the invention, it is believed that the present invention will be better understood from the following description of preferred embodiments.
All percentages used herein are by weight of the dentifrice composition, unless otherwise specified. The ratios used herein are molar ratios of the overall composition, unless otherwise specified. All measurements are made at 25° C., unless otherwise specified.
Herein, “comprising” means that other steps and other components which do not affect the end result can be added. This term encompasses the terms “consisting of” and “consisting essentially of.”
