Abstract

Oral care compositions and/or unit-dose oral care compositions comprising a high level of surfactant. Oral care compositions and/or unit-dose oral care compositions with a high foaming efficiency. Oral care compositions and/or unit-dose oral care compositions with one or more web forming materials, one or more surfactants, and a sugar alcohol.

First claim

What is claimed is:

1. A solid unit-dose oral care composition comprising:
(a) fibrous composition comprising:
(i) from about 1% to about 25%, by weight of the unit-dose oral care composition, of web forming material, the web forming material comprising polyvinyl alcohol;
(ii) from about 0.01% to about 20%, by weight of the unit-dose oral care composition, of surfactant, and
(iii) sugar alcohol;

(b) nonfibrous composition comprising abrasive.

2. The unit-dose oral care composition of claim 1 , wherein the surfactant comprises anionic surfactant, zwitterionic surfactant, or combinations thereof.

3. The unit-dose oral care composition of claim 1 , wherein the surfactant comprises sodium lauryl sulfate, cocamidopropyl betaine, or combinations thereof.

4. The unit-dose oral care composition of claim 1 , wherein the oral care composition comprises a fluoride ion source, 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 0.01% to about 50%, by weight of the unit-dose oral care composition, of the sugar alcohol.

6. The unit-dose oral care composition of claim 5 , wherein the sugar alcohol comprises sorbitol, mannitol, lactitol, isomalt, arabitol, erythritol, glycerol, maltitol, xylitol, or combinations thereof.

7. The unit-dose oral care composition of claim 5 , wherein the sugar alcohol comprises xylitol, sorbitol, glycerin, or combinations thereof.

8. The unit-dose oral care composition of claim 1 , wherein the abrasive comprises a calcium-containing abrasive, silica abrasive, carbonate abrasive, phosphate abrasive, alumina abrasive, or combinations thereof.

9. The unit-dose oral care composition of claim 1 , wherein at least a portion of the nonfibrous composition is in contact with a surface of the fibrous composition.

10. The unit-dose oral care composition of claim 4 , wherein the fluoride ion source comprises stannous fluoride, sodium fluoride, potassium fluoride, amine fluoride, sodium monofluorophosphate, zinc fluoride, or combinations thereof.

11. The unit-dose oral care composition of claim 4 , wherein the stannous ion source comprises stannous fluoride, stannous chloride, or combinations thereof.

12. The unit-dose oral care composition of claim 4 , wherein the zinc ion source comprises zinc citrate, zinc chloride, zinc sulfate, zinc gluconate, zinc lactate, zinc phosphate, zinc arginine, zinc fluoride, zinc iodide, zinc carbonate, or combinations thereof.

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

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