Abstract

An oral care composition comprising a diluted sodium calcium alginate gel, wherein the oral care composition is a toothpaste, a gel, a mouthwash or a mouthrinse.

First claim

The invention claimed is:

1. An oral care composition comprising a diluted sodium calcium alginate gel, wherein the oral care composition is a toothpaste, a gel, a mouthwash or a mouthrinse;
wherein the weight ratio of sodium to calcium in the diluted gel is from 80:20 to 86:14, and
wherein the diluted sodium calcium alginate gel is present in the composition in an amount of about 0.17 wt. %, based on the total weight of the oral care composition; and further comprises water in an amount of from 10 wt. % to 60 wt. %, based on the total weight of the oral care composition.

2. The oral care composition of claim 1 , wherein the composition is a toothpaste or a gel.

3. The oral care composition of claim 1 , wherein the weight ratio of sodium to calcium in the diluted gel is from 81:19 to 86:14.

4. The oral care composition of claim 3 , wherein the weight ratio of sodium to calcium in the diluted gel is about 84:16.

5. The oral care composition of claim 1 , wherein the composition comprises water in an amount of from 15 wt. % to 55 wt. %, based on the total weight of the oral care composition.

6. The oral care composition of claim 5 , wherein the composition comprises water in an amount of from 20 wt. % to 45 wt. %, based on the total weight of the oral care composition.

7. The oral care composition of claim 6 , wherein the composition comprises water in an amount of from 25 wt. % to 35 wt. %, based on the total weight of the oral care composition.

8. The oral care composition of claim 7 , wherein the composition comprises water in an amount of from 28 wt. % to 32 wt. %, based on the total weight of the oral care composition.

9. The oral care composition of claim 1 , wherein the ratio of water to the diluted sodium calcium alginate gel in the composition is from 80:1 to 180:1.

10. The oral care composition of claim 9 , wherein the ratio of water to the diluted sodium calcium alginate gel in the composition is from 85:1 to 150:1.

11. The oral care composition of claim 10 , wherein the ratio of water to the diluted sodium calcium alginate gel in the composition is from 90:1 to 120:1.

12. The oral care composition of claim 11 , wherein the ratio of water to the diluted sodium calcium alginate gel in the composition is from 95:1 to 105:1.

13. The oral care composition of claim 1 , further comprising one or more agents selected from diluents, bicarbonate salts, pH modifying agents, surfactants, foam modulators, additional thickening agents, humectants, sweeteners, flavorants, pigments, antibacterial agents, anticaries agents, fluoride ion sources, anticalculus or tartar control agents, and mixtures thereof.

14. The oral care composition of claim 13 , wherein a humectant is present in an amount of from 35 wt. % to 60 wt. %, based on the total weight of the oral care composition.

15. The oral care composition of claim 14 , wherein the humectant is present in an amount of from 42 wt. % to 53 wt. %, based on the total weight of the oral care composition.

16. The oral care composition of claim 15 , wherein the humectant is present in an amount of about 48 wt. %, based on the total weight of the oral care composition.

17. The oral care composition of claim 13 , wherein the humectant is sorbitol.

18. The oral care composition of claim 13 , wherein a humectant is present in an amount of from 0.5 wt. % to 2 wt. %, based on the total weight of the oral care composition.

19. The oral care composition of claim 18 , wherein the humectant is present in an amount of from 0.7 wt. % to 1.5 wt. %, based on the total weight of the oral care composition.

20. The oral care composition of claim 19 , wherein the humectant is present in an amount of about 1.0 wt. %, based on the total weight of the oral care composition.

21. The oral care composition of claim 18 , wherein the humectant is polyethylene glycol 600.

22. The oral care composition of claim 12 , wherein a silica thickener is present in an amount of from 5 wt. % to 10 wt. %, based on the total weight of the oral care composition.

23. The oral care composition of claim 22 , wherein the silica thickener is present in an amount of about 8 wt. %, based on the total weight of the oral care composition.

24. The oral care composition of claim 1 , wherein the composition does not contain carboxymethylcellulose.

25. The oral care composition of claim 1 , wherein the composition does not contain cellulose polymers.
