Abstract

Oral compositions, such as oral gels, toothpastes and mouthwashes, containing a chelating agent and a hydrophobic anionic surfactant.

Claims

1. A toothpaste composition providing improved oral cleansing with reduced desquamation comprising:

a. from about 0.1% to about 2.5% of a sarcosinate surfactant;

b. from about 0.1% to about 2.5% of a chelating agent selected from the group consisting of tartaric acid and pharmaceutically-acceptable salts thereof, and mixtures thereof;

c. cocoamidopropyl-betaine; and

d. sodium fluoride;

wherein the level of a. and b. does not exceed 4.0% by weight of the total composition and wherein the composition has a pH of from about 6.5 to about 9.5 and wherein said composition is free of enzymes.

2. A toothpaste composition according to claim 1 wherein said tartaric acid salt is selected from the group consisting of sodium tartrate, potassium tartrate, sodium potassium tartrate, and mixtures thereof.

3. A toothpaste composition according to claim 2 wherein said composition has a pH above about 7 and wherein the sarcosinate surfactant is selected from the group consisting of sodium lauroyl sarcosinate, sodium decyl sarcosinate, sodium myristyl sarcosinate, sodium stearyl sarcosinate, sodium palmitoyl sarcosinate, sodium oleoyl sarcosinate and mixtures thereof.

4. A toothpaste composition according to claim 3 further comprising an abrasive.

5. A toothpaste composition according to claim 4 further comprising from about 15% to about 70% of a humectant selected from among the group consisting of glycerin, sorbitol, Propylene glycol and mixtures thereof.

6. A toothpaste composition according to claim 5 wherein the sarcosinate surfactant is sodium lauroyl sarcosinate and the chelating agent is a combination of tartaric acid and sodium tartrate.

7. A method for preventing and treating plaque and gingivitis with reduced desquamation comprising the application of a safe and effective amount of a composition according to claim 1, to the teeth and other oral surfaces.

8. A method for preventing and treating plaque and gingivitis with reduced desquamation comprising the application of a safe and effective amount of a composition according to claim 3, to the teeth and other oral surfaces.

9. A method for preventing and treating plaque and gingivitis with reduced desquamation comprising the application of a safe and effective amount of a composition according to claim 6, to the teeth and other oral surfaces.
