Oral lubricating and stain retarding compositions
An oral lubricant having usefulness for alleviating the symptoms of dry mouth and preventing accumulation of dental stains based on a polyvinyl alcohol polymer containing composition in an orally acceptable carrier or vehicle. The invention relates generally to an oral composition having a function in lubricating the mouth and preventing the formation of stains on the surfaces of the teeth. The active ingredients of the composition are a polyvinyl alcohol, a metal chelating agent, lipophilic vitamin, surface active material and a phenolic anti microbial agent with anti-inflammatory properties.

a hydrolyzed polyvinyl alcohol polymer that forms a film on the surfaces of teeth; fluoride; a metal chelating agent; and
an orally acceptable vehicle selected from the group consisting of tooth paste, tooth gel, lozenges, chewing gum, and mouthwash.
2. The composition of claim 1 wherein the hydrolyzed polyvinyl alcohol is present at a concentration in the range of about 0.005% to about 15% by weight.
3. The composition of claim 1 wherein the metal chelating agent is selected from the group consisting of sodium pyrophosphate, sodium tripolyphosphate, sodium hexametaphosphate, phosphonic acid, di and tri phosphonic acid compound or its salts, oxalic acid or its salts, alpha hydroxy acids or their salts, and any combination thereof.
4. The composition of claim 1 wherein the metal chelating agent is present at a concentration in the range of about 0.01% to about 10.0% by weight.
5. The composition of claim 1 wherein the composition further comprises one or more fat soluble vitamins selected from the group consisting of vitamin A or its derivative, Vitamin D or its derivative, Vitamin E or its derivative, and any combination thereof and are present at a concentration in the range of about 0.01% to about 10.0% by weight.
6. The composition of claim 1 wherein the composition further comprises a surface active material.
7. The composition according to claim 6 wherein the surface active material is selected from the group consisting of ionic surfactants, non-ionic surfactants, and any combination thereof.
8. The composition according to claim 6 wherein the surface active material is one or more compounds selected from the group consisting of polyoxyethylene-polyoxypropylene block copolymers, polyoxyethylene sorbitan monolaurate, sodium lauryl sulfate, betaine, and any combination thereof and is present at a concentration in the range of about 0.25% to about 25% by weight.
9. The composition of claim 1 wherein the composition further comprises an anti-inflammatory agent having anti-microbial properties.
10. The composition of claim 9 wherein the anti-inflammatory agent is a phenolic compound.
11. The composition of claim 10 wherein the anti-inflammatory agent is triclosan.
12. The composition of claim 11 wherein the concentration of triclosan is in the range of about 0.05% to about 1.0% by weight.
13. A composition for lubricating the mouth and preventing accumulation of dental stain, comprising:
a hydrolyzed polyvinyl alcohol polymer that forms a film in an oral cavity;
fluoride; a metal chelating agent;
an orally acceptable vehicle selected from the group consisting of tooth paste, tooth gel, lozenges, chewing gum and mouthwash; and
wherein the composition is administered in an amount effective to lubricate the mouth and prevent accumulation of dental stain.
14. The composition of claim 13 wherein the polyvinyl alcohol polymer is present at a concentration in the range of about 0.005% to about 15% by weight.
15. The composition of claim 13 wherein the metal chelating agent is selected from the group consisting of sodium pyrophosphate, sodium tripolyphosphate, sodium hexametaphosphate, phosphonic acid, di and tri phosphonic acid compound or its salts, oxalic acid or its salts, alpha hydroxy acids or their salts, and any combination thereof.
16. The composition of claim 13 wherein the metal chelating agent is present at a concentration in the range of about 0.01% to about 10.0% by weight.
17. The composition of claim 13 wherein the composition further comprises one or more fat soluble vitamins selected from the group consisting of vitamin A or its derivatives, Vitamin D or its derivatives, Vitamin E or its derivatives, and any combination thereof and are present at a concentration in the range of about 0.01% to about 10.0% by weight.
18. The composition of claim 13 wherein the composition further comprises a surface active material.
19. The composition of claim 18 wherein the surface active material is selected from the group consisting of ionic surfactants, non-ionic surfactants, and any combination thereof.
20. The composition of claim 18 wherein the surface active material is one or more compounds selected from the group consisting of polyoxyethylene-polyoxypropylene block copolymers, polyoxyethylene sorbitan monolaurates, lauryl sulfates, betaines, and any combination thereof and is present at a concentration in the range of about 0.25% to about 25% by weight.
