A tooth whitening product is provided. The tooth whitening product has a backing layer and a tooth whitening composition. The tooth whitening composition includes first and second water soluble polymers, water, and a tooth whitening agent, wherein the first water soluble polymer is polyethelene oxide and the second water soluble polymer is polyvinyl alcohol.
1. A tooth whitening product in the form of a strip, comprising: a backing layer;a tooth whitening composition comprising a mixture of first and second polymers, water, and a tooth whitening agent, wherein said first polymer is polyethylene oxide and said second polymer is polyvinyl alcohol;said pro
1. A tooth whitening product in the form of a strip, comprising: a backing layer;a tooth whitening composition comprising a mixture of first and second polymers, water, and a tooth whitening agent, wherein said first polymer is polyethylene oxide and said second polymer is polyvinyl alcohol;said product comprising a fibrous web, scrim or mesh comprising fibers arranged to provide void spaces, wherein the spacing between fibers is at least about 1 micron, said web, scrim or mesh having a coating or layer of said whitening composition applied thereto. 2. The tooth whitening product of claim 1, wherein the concentration of said first polymer is between about 10% and about 90% by weight of said tooth whitening composition. 3. The tooth whitening product of claim 1, wherein the concentration of said second polymer is between about 0.5% and about 50% by weight of said tooth whitening composition. 4. The tooth whitening product of claim 1, wherein the concentration of said water is between about 2% and about 90% by weight of said tooth whitening composition. 5. The tooth whitening product of claim 1, wherein said tooth whitening composition further comprises a plasticizer having a concentration between about 1% and about 80% by weight of said tooth whitening composition. 6. The tooth whitening product of claim 5, wherein said plasticizer is polyethylene glycol. 7. The tooth whitening product of claim 1, wherein said polyvinyl alcohol has a hydrolysis between about 70% and about 91%. 8. The tooth whitening product of claim 1, wherein said backing layer is a laminate. 9. The tooth whitening product of claim 1, wherein said polyethylene oxide has an average molecular weight between about 300,000 and about 900,000. 10. The tooth whitening product of claim 1, wherein said tooth whitening composition comprises a mixture of two or more polyethylene oxides and wherein said polyethylene oxides have different average molecular weights. 11. The tooth whitening product of claim 1, wherein said tooth whitening agent is hydrogen peroxide. 12. The tooth whitening product of claim 1, wherein said first and second polymers are water soluble. 13. A method of manufacturing the tooth whitening product of claim 1 comprising: mixing a first mixture comprising polyethylene oxide and a first solvent;mixing a second mixture comprising polyvinyl alcohol and a second solvent;adding said first and second mixtures to form a third mixture;mixing a tooth whitening agent with said third mixture to provide a tooth whitening composition and incorporating into said composition a fibrous web, scrim or mesh comprising fibers arranged to provide void spaces, wherein the spacing between fibers is at least about 1 micron to provide a tooth whitening strip. 14. The method of claim 13, wherein said first and second solvents are water. 15. The method of claim 13, wherein said first and second solvents are different. 16. The method of claim 13, wherein one of said first and second solvents comprises a mixture of solvents.
