Abstract

An oral care composition including greater than 0.0% of an antimicrobial agent that is cetylpyridinium chloride (CPC), a cationic surfactant, an emulsifier, and less than 0.5% by weight of a thickener, such as hydroxyethylcellulose.

Claims (30)

1. A liquid oral composition comprising:

0.01% by weight to 0.4% by weight of an antimicrobial agent that is cetylpyridinium chloride (CPC);

0.005% by weight to 0.05% by weight of a cationic surfactant that is 2-pyrrolidone-5-carboxylic acid (PCA) ethyl cocoyl arginate;

0.05% by weight to 2% by weight of an emulsifier that is a poly(oxyethylene) hydrogenated castor oil that has an average molar number of ethylene oxide units added of 35 to 100 moles; and

0.1% by weight to 0.3% by weight of a thickener that is a non-ionic polymer.

2. The composition of claim 1 , wherein the composition includes 0.02% by weight to 0.1% by weight CPC.

3. The composition of claim 1 , wherein the composition includes 0.005% by weight to 0.02% by weight PCA ethyl cocoyl arginate.

4. The composition of claim 1 , wherein the emulsifier is PEG-60 hydrogenated castor oil.

5. The composition of claim 4 , wherein the composition includes 0.1% by weight to 0.5% by weight PEG-60 hydrogenated castor oil.

6. The composition of claim 1 , wherein the thickener is hydroxyethylcellulose.

7. The composition of claim 1 , wherein the composition includes one or more additional surfactants, soothing agents, desensitizing agents, flavoring agents, sweetening agents, humectant agents, coloring agents, antimicrobial agents, binders, thickening agents, fluoride, preservatives, and water.

8. The composition of claim 1 , wherein the composition does not include an anionic surfactant.

9. The composition of claim 1 , wherein the composition is a mouthwash or mouth spray.

10. The composition of claim 1 , wherein, the emulsifier is PEG-60 hydrogenated castor oil, and the thickener is hydroxyethylcellulose, and wherein the composition includes 0.05% by weight to 0.1% by weight CPC, 0.005% by weight to 0.02% by weight PCA ethyl cocoyl arginate, 0.1% by weight to 0.5% by weight PEG-60 hydrogenated castor oil, and 0.1% by weight to 0.2% by weight hydroxyethylcellulose.

11. A liquid oral composition comprising:

0.01% by weight to 0.4% by weight cetylpyridinium chloride (CPC);

0.005% by weight to 0.05% by weight 2-pyrrolidone-5-carboxylic acid (PCA) ethyl cocoyl arginate;

0.05% by weight to 2% by weight PEG-60 hydrogenated castor oil; and

0.1% by weight to 0.3% by weight of hydroxyethylcellulose.

12. The composition of claim 11 , wherein the composition includes 0.02% by weight to 0.1% by weight CPC, 0.005% by weight to 0.02% by weight PCA ethyl cocoyl arginate, and 0.1% by weight to 0.5% by weight PEG-60 hydrogenated castor oil.

13. The composition of claim 11 , wherein the composition includes 0.05% by weight to 0.1% by weight CPC, 0.005% by weight to 0.02% by weight PCA ethyl cocoyl arginate, 0.1% by weight to 0.5% by weight PEG-60 hydrogenated castor oil, and 0.1% by weight to 0.2% by weight hydroxyethylcellulose.

14. The composition of claim 11 , wherein the composition includes one or more additional surfactants, soothing agents, desensitizing agents, flavoring agents, sweetening agents, humectant agents, coloring agents, antimicrobial agents, binders, thickening agents, fluoride, preservatives, and water.

15. The composition of claim 11 , wherein the composition does not include an anionic surfactant.

16. The composition of claim 11 , wherein the composition is a mouthwash or mouth spray.

17. A method of treating teeth comprising:

applying a liquid oral composition to an oral cavity, the liquid oral composition including 0.01% by weight to 0.4% by weight of an antimicrobial agent that is cetylpyridinium chloride (CPC);

0.005% by weight to 0.05% by weight of a cationic surfactant that is 2-pyrrolidone-5-carboxylic acid (PCA) ethyl cocoyl arginate;

0.05% by weight to 2% by weight of an emulsifier that is a poly(oxyethylene) hydrogenated castor oil that has an average molar number of ethylene oxide units added of 35 to 100 moles; and

0.1% by weight to 0.3% by weight of a thickener that is a non-ionic polymer.

18. The method of claim 17 , wherein the emulsifier is PEG-60 hydrogenated castor oil, and the thickener is hydroxyethylcellulose, and wherein the composition includes 0.05% by weight to 0.1% by weight CPC, 0.005% by weight to 0.02% by weight PCA ethyl cocoyl arginate, 0.1% by weight to 0.5% by weight PEG-60 hydrogenated castor oil, and 0.1% by weight to 0.2% by weight hydroxyethylcellulose.
