Abstract

Oral care compositions and/or unit-dose oral care compositions with a fluoride ion source. Oral care compositions and/or unit-dose oral care compositions with a high average fluoride ion uptake. Oral care compositions with one or more web forming materials, a calcium ion source, and a fluoride ion source with a high average fluoride uptake.

First claim

What is claimed is:

1. A solid unit-dose oral care composition comprising:
(a) nonwoven web composition comprising web forming material;
(b) fluoride ion source; and
(c) abrasive.

2. The unit-dose oral care composition of claim 1 , wherein the fluoride ion source comprises sodium fluoride, sodium monofluorophosphate, stannous fluoride, amine fluoride, or combinations thereof.

3. The unit-dose oral care composition of claim 1 , wherein the composition comprises from about 0.01% to about 10%, by weight of the unit-dose oral care composition, of metal ion source.

4. The unit-dose oral care composition of claim 3 , wherein the metal ion source comprises stannous ion source, zinc ion source, or combinations thereof.

5. The unit-dose oral care composition of claim 1 , wherein the unit-dose oral care composition comprises from about 1% to about 50%, by weight of the unit-dose oral care composition, of the web forming material.

6. The unit-dose oral care composition of claim 5 , wherein the web forming material comprises starch, polyvinyl alcohol, polyvinyl pyrrolidone, polyethylene oxide, carboxymethylcellulose, polyacrylic acid, polyvinyl ether maleic acid copolymer, or combinations thereof.

7. The unit-dose oral care composition of claim 1 , wherein the unit-dose oral care composition has from about 0.01% to about 10%, by weight of the unit-dose oral care composition, of the fluoride ion source.

8. The unit-dose oral care composition of claim 1 , wherein the unit-dose oral care composition has at least about a 1500 ppm fluoride uptake.

9. The unit-dose oral care composition of claim 1 , wherein the unit-dose oral care composition comprises from about 0.01% to about 40%, by weight of the unit-dose oral care composition, of calcium ion source.

10. The unit-dose oral care composition of claim 9 , wherein the calcium ion source comprises calcium abrasive, calcium salt, or combinations thereof.

11. The unit-dose oral care composition of claim 9 , wherein the unit-dose oral care composition has at least about a 1000 ppm average fluoride uptake.

12. The unit-dose oral care composition of claim 9 , wherein the unit-dose oral care composition has at least about a 2000 ppm average fluoride uptake.

13. The unit-dose oral care composition of claim 5 , wherein the unit-dose oral care composition comprises from about 0.01% to less than 10%, by weight of the unit-dose oral care composition, of the web forming material.

14. A solid unit-dose oral care composition comprising:
(a) nonwoven web composition comprising web forming material;
(b) calcium ion source; and
(c) fluoride ion source, wherein the unit-dose oral care composition has an average fluoride uptake of at least about 1000 ppm.

15. The unit-dose oral care composition of claim 14 , wherein the calcium ion source comprises calcium abrasive, calcium salt, or combinations thereof.

16. The unit-dose oral care composition of claim 14 , wherein the calcium ion source comprises calcium salt and the unit-dose oral care composition comprises abrasive.

17. The unit-dose oral care composition of claim 14 , wherein the calcium ion source and the fluoride ion source are physically separated or in different phases.

18. The unit-dose oral care composition of claim 14 , wherein the unit-dose oral care composition comprises from about 1% to about 50%, by weight of the unit-dose oral care composition, of the web forming material.

19. The unit-dose oral care composition of claim 14 , wherein the unit-dose oral care composition comprises from about 0.01% to about 10%, by weight of the unit-dose oral care composition, of the fluoride ion source.

20. The unit-dose oral care composition of claim 14 , wherein the unit-dose oral care composition comprises from about 0.01% to about 40%, by weight of the unit-dose oral care composition, of the calcium ion source.

21. The unit-dose oral care composition of claim 14 , wherein the fluoride ion source comprises sodium fluoride, sodium monofluorophosphate, stannous fluoride, amine fluoride, or combinations thereof.
