Abstract

Oral care compositions having polyethylene glycol are more phase stable, particularly with certain flavorants that have a specified range of Dielectric Constant and/or water number and/or C log P value.

First claim

What is claimed is:

1. A dentifrice composition comprising:
(a) 50% to 70% 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 4% of a polyethylene glycol (PEG) 900 to PEG 1300 by weight of the composition; and
(d) 0.001% to 5% of a flavorant composition by weight of the dentifrice composition, wherein the flavorant composition has a Dielectric Constant (DEC) from 1 to 15; and
wherein the flavorant composition has a Water Number (WN) from 1 to 50;
wherein the composition comprises less than 0.5% of a humectant, by weight of the composition, the composition does not phase separate after four months under ambient conditions, and the pH is greater than 9.

2. The composition of claim 1 , wherein the humectant is selected from the group consisting of glycerin, sorbitol, xylitol, butylene glycol, propylene glycol, and combinations thereof.

3. The composition of claim 1 , wherein the flavorant composition is comprised of flavor ingredients wherein at least 50%, of the flavor ingredient(s) by weight of the flavorant composition having a C log P value of at least 3.06 and higher.

4. The composition of claim 3 , wherein the flavorant composition is comprised of flavor ingredients wherein at least 60% of the flavor ingredient(s) by weight of the flavorant composition having a C log P value of at least 4.26 and higher.

5. The composition of claim 4 , wherein the flavorant composition is comprised of flavor ingredients wherein at least 50% of the flavor ingredient(s) by weight of the flavorant composition having a C log P value of at least 4.26 and higher.

6. The composition of claim 1 , wherein the flavorant composition comprises at least 40% of L-menthol as a flavorant ingredient by weight of the flavorant composition.

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

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

9. A method of treating tooth enamel comprising the step of brushing teeth with the dentifrice composition of claim 8 .

10. The composition of claim 1 , wherein the composition comprises 0.1% to 3% of a polyethylene glycol (PEG) 900 to PEG 1300 by weight of the composition.

11. A dentifrice composition comprising:
(a) 50% to 70% of water by weight of the composition;
(b) 25% to 40% of a calcium-containing abrasive by weight of the composition;
(c) 0.1% to 4% of a polyethylene glycol (PEG) 900 to PEG 1300 by weight of the composition;
(d) 0.001% to 5% of a flavorant composition by weight of the dentifrice composition wherein the flavorant composition has a Dielectric Constant (DEC) from 1 to 15; and
wherein the flavorant composition has a Water Number (WN) from 1 to 50;
wherein the composition less than 1% of a humectant, by weight of the composition, the composition does not phase separate after four months under ambient conditions, and the pH is greater than 9.
