Abstract

A oral care composition comprising 20% to 75% of water by weight of the composition; 25% to 60% of a calcium-containing abrasive by weight of the composition; 0.1% to 15%, of a polyethylene glycol (PEG) by weight of the composition; and 0.001% to 5% of a flavorant composition by weight of the oral care composition.

First claim

What is claimed is:

1. An oral care composition comprising:
(a) water;
(b) 0.1% to 4% of a polyethylene glycol (PEG) by weight of the composition; wherein the PEG has an average molecular weight range from 400 Daltons to 800 Daltons;
(c) 0.001% to 5% of a flavorant composition by weight of the oral care composition wherein the flavorant composition has a Dielectric Constant (DEC) from 1 to 8; and
wherein the flavorant composition has a Water Number (WN) from 1 to 25;
wherein the flavorant composition is comprised of flavor ingredients wherein at least 50% of the said ingredients by weight of the flavorant composition have a ClogP value of at least 3.06 and higher;
wherein the flavorant composition comprises from 45% to 95% of L-menthol by weight of the flavorant composition; and
wherein the composition comprises less than 0.5%, by weight of the composition, of a humectant selected from glycerin, sorbitol, xylitol, butylene glycol, propylene glycol, and combinations thereof.

2. The composition of claim 1 , wherein the PEG has an average molecular weight range from 500 Daltons to 700 Daltons.

3. The composition of claim 1 , wherein the flavorant composition is comprised of flavor ingredients wherein from 65% to 95% of the flavor ingredients by weight of the flavorant composition have a ClogP value from 4.26 to 6.

4. The composition according to claim 1 having a pH is greater than pH 7.8.

5. The composition according to claim 4 , wherein the pH is from 9 to 12.

6. The composition according to claim 1 , wherein the water comprises from 20% to 75% by weight of the composition.

7. The composition according to claim 1 , wherein the oral care composition is a toothpaste.

8. The composition according to claim 1 , further comprising a calcium-containing abrasive.

9. The composition according to claim 1 , wherein the oral care composition is a rinse.

10. The composition according to claim 1 , further comprising from 0.025% to 9% of a surfactant, by weight of the composition.

11. The composition of claim 1 , further comprising:
(a) 0.025% to 9% of a surfactant, by weight of the composition;
(b) 25% to 60% of a calcium-containing abrasive, by weight of the composition; and
wherein the PEG has an average molecular weight range from 500 Daltons to 700Daltons;
wherein the oral care composition is a toothpaste and has a pH from 9 to 12.

12. An oral care composition comprising:
(a) 0.1% to 4% of a polyethylene glycol (PEG), by weight of the composition, wherein the PEG has an average molecular weight range from 550 Daltons to 650 Daltons;
(b) 0.001% to 5% of a flavorant composition, by weight of the oral care composition, wherein the flavorant composition has a Dielectric Constant (DEC) from 1 to 8; wherein the flavorant composition has a Water Number (WN) from 1to 25;
wherein the flavorant composition comprises from 45% to 95% of L-menthol by weight of the flavorant composition;
wherein the flavorant composition is comprised of flavor ingredients wherein at least 50% of the said ingredients by weight of the flavorant composition have a ClogP value of at least 3.06 and higher; and
wherein the composition comprises less than 0.5%, by weight of the oral care composition, of a humectant selected from glycerin, sorbitol, xylitol, butylene glycol, propylene glycol, and combinations thereof.

13. The composition of claim 12 , further comprising 20% to 75% water, by weight of the composition.

14. The composition of claim 13 , further comprising 25% to 60% of a calcium-containing abrasive, by weight of the composition.

15. The composition of claim 14 , wherein the oral care composition is a toothpaste.

16. An oral care composition comprising:
(a) 0.1% to 4% of a polyethylene glycol (PEG) by weight of the composition; wherein the PEG has an average molecular weight range from 500 Daltons to 700 Daltons;
(b) 0.001% to 5% of a flavorant composition by weight of the oral care composition wherein the flavorant composition has a Dielectric Constant (DEC) from 1 to 8; and
wherein the flavorant composition has a Water Number (WN) from 1 to 25, wherein the flavorant composition further comprises from 45% to 95% of L-menthol, by weight of the flavorant composition;
wherein the flavorant composition is comprised of flavor ingredients wherein at least 50% of the said ingredients by weight of the flavorant composition have a ClogP value of at least 3.06 and higher; and
wherein the composition comprises less than 0.5%, by weight of the composition, of a humectant selected from glycerin, sorbitol, xylitol, butylene glycol, propylene glycol, and combinations thereof.

17. The composition of claim 16 , further comprising 20% to 75% water, by weight of the composition.

18. The composition of claim 17 , further comprising 25% to 60% of a calcium-containing abrasive, by weight of the composition.
