Methods for improving taste and oral care compositions with improved taste

1. A method for improving taste of an oral care composition, comprising:

mixing into an oral care composition, vanitrope; from about 0.001% to about 0.025% by weight of the composition, vanillyl butyl ether; from about 0.01% to about 0.15%, by weight of the composition, zingerone; and from about 0.05% to about 11%, by weight of the composition, metal salt selected from the group consisting of a zinc salt, stannous salt, potassium salt, copper salt, and mixtures thereof.

2. The method of claim 1 , further comprising adding capsaicin, capsiate, shoagol, gingerol, piperine, or a combination thereof, to the oral care composition.

3. The method of claim 1 , further comprising adding to the oral care composition a TRPV1 enhancer selected from the group consisting of damascone, geranyl butyrate, 2-octanone, furfural, ionone, 2,6-dimethyl-5-heptenal, tetrasodium pyrophosphate, alpha dimethyl phenethyl acetate, phenylacetaldehyde dimethyl acetal, kephalis, linalool oxide, carvyl acetate, farnesene, trans-2-hexenyl acetate, heptyl alcohol, and combinations thereof.

4. The method of claim 1 , wherein the vanillyl butyl ether is present in an amount from 0.002% to 0.02% by weight of the oral care composition.

5. The method of claim 1 , wherein the stannous salt is present and is selected from the group consisting of stannous fluoride, stannous chloride, stannous iodide, stannous chlorofluoride, stannous actetate, stannous hexafluorozirconate, stannous sulfate, stannous lactate, stannous tartrate, stannous gluconate, stannous citrate, stannous malate, stannous glycinate, stannous pyrophosphate, stannous metaphosphate, stannous oxalate, stannous phosphate, stannous carbonate, and combinations thereof.

6. The method of claim 1 , wherein the zinc salt is present and is selected from the group consisting of zinc fluoride, zinc chloride, zinc iodide, zinc chlorofluoride, zinc acetate, zinc hexafluorozirconate, zinc sulfate, zinc lactate, zinc tartrate, zinc gluconate, zinc citrate, zinc malate, zinc glycinate, zinc pyrophosphate, zinc metaphosphate, zinc oxalate, zinc phosphate, zinc carbonate, zinc oxide, and combinations thereof.

7. The method of claim 1 , wherein the potassium salt is present and is selected from the group consisting of potassium nitrate, potassium citrate, potassium oxalate, potassium bicarbonate, potassium acetate, potassium chloride, and combinations thereof.

8. The method of claim 1 , wherein the vanitrope is present in an amount from about 0.01% to about 0.15% by weight of the oral care composition.

9. The method of claim 1 , wherein the metal salt is zinc citrate and wherein the metal salt is present in an amount from about 0.05% to about 5.0% by weight of the oral care composition.

10. The method of claim 1 , wherein vanitrope is present in an amount from about 0.05% to about 0.15% by weight of the oral care composition.

11. The method of claim 1 , wherein the oral care composition further comprises from about 5% to about 80% by weight water.

12. The method of claim 1 , wherein from about 0.006% to about 0.025%, by weight of the composition, of vanillyl butyl ether is added.

13. The method of claim 1 , wherein from about 0.02% to about 0.04%, by weight of the composition, of vanitrope is added.

14. The method of claim 1 , wherein from about 0.02% to about 0.04%, by weight of the composition, of zingerone is added.

15. The method of claim 1 , wherein the metal salt is zinc citrate.

16. A method for improving taste of an oral care composition, comprising: mixing from about 0.02% to about 0.04%, by weight of the composition, of vanitrope; from about 0.001% to about 0.025% by weight of the composition, vanillyl butyl ether; from about 0.02% to about 0.04%, by weight of the composition, zingerone; and zinc citrate.
