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) 40% to 75% of water by weight of the composition;
(b) 25% to 60% of a calcium-containing abrasive by weight of the composition;
(c) 0.1% to 15%, 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;
(d) 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 composition does not phase separate after four months, under ambient conditions.

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 composition is free of a polyol selected from glycerin, sorbitol, xylitol, butylene glycol, propylene glycol, and combinations thereof .

4. The composition of any of claim 1 , 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.

5. The composition of claim 4 , 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.

6. The composition of claim 1 , wherein the flavorant composition comprises from 45% to 95% of L-menthol by weight of the flavorant composition.

7. The composition of claim 1 , further comprising a fluoride ion source.

8. A composition according to claim 7 , wherein the fluoride ion source comprises from 0.0025% to 2% of sodium monoflurophosphate by weight of the composition.

9. The composition of claim 1 , wherein the pH is alkaline.

10. A composition according to claim 9 wherein the pH is from 9 to 12 .

11. The composition of claim 1 , further comprising 0.1% to 5% of sodium lauryl sulfate by weight of the composition.

12. A method of treating tooth enamel comprising the step of contacting teeth with the oral care composition of claim 1 .

13. The composition of claim 1 , wherein the PEG has an average molecular weight range from 550 Daltons to 650 Daltons.

14. An oral care composition comprising:
(a) 40% to 75% of water by weight of the composition;
(b) an abrasive;
(c) a fluoride ion source;
(d) 0.1% to 5% of sodium lauryl sulfate by weight of the composition;
(e) 0.1% to 15%, 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;
(d) 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 composition does not phase separate after four months, under ambient conditions.

15. The composition of claim 14 , wherein the PEG has an average molecular weight range from 550 Daltons to 650 Daltons.
