Title: Viscoelastic dentifrice composition
Abstract:A toothpaste or dental gel composition containing an amount of a synthetic linearly viscoelastic cross-linked polymeric thickening agent, especially a cross-linked methyl vinyl ether/maleic anhydride copolymer, effective to render the composition linearly viscoelastic, and a method of promoting oral hygiene by applying an effective amount of the composition to dental surface.
Inventor(s): Prencipe; Michael (East Windsor, NJ), Durga; Gary A. (Edison, NJ)
Assignee: Colgate-Palmolive Company (Piscataway, NJ)
Filing Date:Aug 01, 1991
Application Number:07/738,766
Claims:1. A linear viscoelastic dentifrice composition in the form of a toothpaste or dental gel with a pH of about 4 to about 9 comprising an orally acceptable water/humectant vehicle, an orally acceptable dental polishing agent and, in an amount effective to render the composition linearly viscoelastic, a synthetic linearly viscoelastic cross-linked polymeric thickening agent having in a 1 wt. % aqueous solution an elastic or storage modulus G' and a viscous or loss modulus G" substantially independent of frequency in an applied frequency range of 0.1 to 100 radians/sec, a G' minimum value of 1,000 dynes/sq. cm which varies less than 1 order of magnitude of its original value, and a ratio of G"/G' ranging from more than 0.05 to less than 1.

2. A composition according to claim 1 containing approximately by weight, 6% to 50% of water, 20% to 70% of humectant, 5 to 70% of dental polishing agent, and 0.02% to 5% of said polymeric thickening agent containing at least about 3% of cross-linking agent.

3. A composition according to claim 1 wherein said polymeric thickening agent contains a plurality of carboxylic, phosphonic, phosphinic or sulfonic acid or acid salt groups or mixtures thereof.

4. A composition according to claim 3 wherein the said polymeric thickening agent is made with a cross-linking agent containing at least two ethylenically unsaturated groups or at least two groups reactive with pendant reactive groups along the polymer chain of the polymeric thickening agent.

5. A composition according to any one of claims 1 to 4 wherein said polymeric thickening agent comprises a copolymer of maleic acid or anhydride with another ethylenically unsaturated monomer.

6. A composition according to claim 5 wherein said other monomer comprises methyl vinyl ether.

7. A composition according to claim 6 wherein said copolymer is made with 1,7-octadiene, 1,9-decadiene, or polyethylene glycol as cross-linking agent.

8. A composition according to any one of claims 1 to 4 wherein the polymeric thickening agent has a molecular weight of about 1,000 to about 5,000,000.

9. A composition according to claim 6 wherein the polymeric thickening agent has a molecular weight of about 1,000 to about 5,000,000.

10. A composition according to any one of claims 1 to 4 further containing an amount of a fluoride ion source sufficient to supply about 25 ppm to about 5,000 ppm of fluoride ions.

11. A composition according to claim 6 further containing an amount of a fluoride ion source sufficient to supply about 25 ppm to about 5,000 ppm of fluoride ions.

12. A composition according to claim 8 further containing an amount of a fluoride ion source sufficient to supply about 25 ppm to about 5,000 ppm of fluoride ions.

13. A composition according to any of claims 1 to 4 further containing about 0.4 to about 3 parts of xanthan gum or carboxymethyl cellulose per part of the cross-linked polymeric thickening agent.

14. A composition according to claim 6 further containing about 0.4 to about 3 parts of xanthan gum or carboxymethyl cellulose per part of the cross-linked polymeric thickening agent.

15. A composition according to claim 8 further containing about 0.4 to about 3 parts of xanthan gum or carboxymethyl cellulose per part of the cross-linked polymeric thickening agent.

16. A composition according to claim 10 further containing about 0.4 to about 3 parts of xanthan gum or carboxymethyl cellulose per part of the cross-linked polymeric thickening agent.

17. A method of promoting oral hygiene comprising applying to dental surface an effective amount of a composition as defined in any one of claims 1 to 4.

18. A method of promoting oral hygiene comprising applying to dental surface an effective amount of a composition as defined in claim 6.

19. A method of promoting oral hygiene comprising applying to dental surface an effective amount of a composition as defined in claim 8.

20. A method of promoting oral hygiene comprising applying to dental surface an effective amount of a composition as defined in claim 10.

21. A method of promoting oral hygiene comprising applying to dental surface an effective amount of a composition as defined in claim 13.
