Abstract

An oral care composition with tin, polyol with five or more carbon atoms, water, and a pH of greater than 7. An oral care composition with a tin ion source, a fluoride ion source, a polyol with five or more carbon atoms, water, and a pH of greater than 7. Oral care compositions with a high tin ion availability.

Claims (23)

1. A dentifrice composition comprising:

(a) stannous chloride;

(b) from about 5% to about 50%, by weight of the composition, of polyol comprising five or more carbon atoms; and

wherein the composition has a pH of greater than 7.

2. The composition of claim 1 , wherein the pH is from about 8 to about 9.5.

3. The composition of claim 1 , wherein the polyol comprises xylitol, sorbitol, or combinations thereof.

4. The composition of claim 1 , wherein the composition comprises abrasive.

5. The composition of claim 4 , wherein the abrasive comprises silica abrasive, calcium abrasive, or combinations thereof.

6. The composition of claim 5 , wherein the calcium abrasive comprises calcium carbonate, calcium pyrophosphate, dicalcium phosphate, or combinations thereof.

7. The composition of claim 1 , wherein the composition comprises zinc.

8. The composition of claim 7 , wherein the zinc comprises zinc lactate, zinc oxide, zinc phosphate, zinc chloride, zinc acetate, zinc hexafluorozirconate, zinc sulfate, zinc tartrate, zinc gluconate, zinc citrate, zinc malate, zinc glycinate, zinc pyrophosphate, zinc metaphosphate, zinc oxalate, zinc carbonate, or combinations thereof.

9. The composition of claim 1 , wherein the composition comprises from about 0.01% to about 15%, by weight of the composition, of surfactant.

10. The composition of claim 9 , wherein the surfactant comprises sodium lauryl sulfate, sodium cocoyl glutamate, cocamidopropyl betaine, or combinations thereof.

11. The composition of claim 1 , wherein the composition comprises thickening agent, the thickening agent comprising xanthan gum, carrageenan, a polyethylene glycol, a crosslinked polyacrylic acid polymer, or combinations thereof.

12. The composition of claim 1 , wherein the composition comprises fluoride.

13. The composition of claim 12 , wherein the fluoride comprises sodium fluoride, stannous fluoride, sodium monofluorophosphate, amine fluoride, zinc fluoride, or combinations thereof.

14. The composition of claim 1 , wherein the composition is free of silica abrasive.

15. The composition of claim 1 , wherein the composition comprises polyphosphate.

16. The composition of claim 15 , wherein the polyphosphate comprises pyrophosphate, tripolyphosphate, tetrapolyphosphate, sodaphos polyphosphate, hexaphos polyphosphate, benephos polyphosphate, hexametaphosphate, or combinations thereof.

17. The composition of claim 1 , wherein the composition is free of polyphosphate.

18. The composition of claim 1 , wherein the composition is free of fluoride.

19. The composition of claim 1 , wherein the composition comprises from about 10% to about 45%, by weight of the composition, of water.
