Abstract

A oral care composition includes: (a) a hydrophilic film-forming polymer; and (b) a hydrophobic carrier, wherein the hydrophilic film-forming polymer is a film-forming polymer effective to occlude dentinal tubules and the oral care composition contains 0-10 wt. % water. The hydrophilic film-forming polymer is preferably GANTREZ S. The hydrophobic carrier is preferably a vegetable oil. A method of cleaning teeth includes applying to the teeth the oral care composition such that the hydrophilic film-forming polymer occludes dentinal tubules. A toothbrush includes: a handle; a head mounted to the handle, the head comprising an outer surface and a plurality of tooth cleaning elements extending outwardly from the outer surface; and a gelatin capsule containing the oral care composition positioned on the head.

First claim

What is claimed is:

1. A oral care composition comprising:
(a) a hydrophilic film-forming polymer; and
(b) a hydrophobic carrier,
wherein the polymer is effective to occlude dentinal tubules and the oral care composition contains less than 10 wt. % water,
wherein the hydrophilic film-forming polymer constitutes 2-5 wt. % of the oral care composition and is an acid form of a copolymer of maleic anhydride,
wherein the hydrophobic carrier constitutes 55-85 wt % of the oral compositions, and wherein the oral care composition further comprises a polyphosphate
wherein the polyphosphate constitutes 1-7 wt. % of the oral care composition and comprises at least one member selected from the group consisting of TetraPotassium Pyrophosphate (TKPP) and Tetra Sodium Pyrophosphate (TSPP), and combinations thereof; and
wherein the oral composition comprises arginine.

2. The oral care composition of claim 1 , wherein the oral care composition contains less than 1 wt. % water.

3. The oral care composition of claim 1 , wherein the hydrophobic carrier comprises at least one member selected from the group consisting of an oil, a wax and silicone.

4. The oral care composition of claim 3 , wherein the hydrophobic carrier comprises vegetable oil and/or silicone oil.

5. The oral care composition of claim 4 , wherein the hydrophobic carrier comprises a C6 to C12 triglyceride.

6. The oral care composition of claim 1 , wherein the polyphosphate constitutes 1-7 wt. % of the oral care composition.

7. The oral care composition of claim 1 , having a flow reduction greater than 60% as measured with a flow-meter attached to a Pashley's cell.

8. The oral care composition of claim 1 , wherein the oral care composition further comprises 5-25 wt. % of a flavoring agent and 0.1-5 wt. % of a sweetening agent.

9. The oral care composition of claim 1 , wherein the oral care composition further comprises at least one member selected from the group consisting of an abrasive, an anti-bacterial agent, a foaming agent, a whitening agent, an anti-calculus agent, a tartar control agent, an anti-inflammatory agent, an anticaries agent, a flavoring agent, a sweetening agent and a colorant.

10. The oral care composition of claim 1 , wherein the oral care composition is encapsulated within a capsule comprising gelatin.

11. The oral care composition of claim 1 , wherein the oral care composition is a solid at 21° C.

12. A method of cleaning teeth comprising applying to the teeth the oral care composition of claim 1 such that the hydrophilic film-forming polymer occludes dentinal tubules.

13. A toothbrush comprising:
a handle;
a head mounted to the handle, the head comprising an outer surface and a plurality of tooth cleaning elements extending outwardly from the outer surface; and
a gelatin capsule containing the oral care composition of claim 1 positioned on the head.
