Abstract

A composition comprising a film or a plurality of film fragments entrained in a carrier is disclosed. The film or plurality of film fragments can comprise a functional material. The film or plurality of film fragments can comprise repeated shapes. Also disclosed is a composition comprising a plurality of discernable lamellar fragments entrained in a carrier. Also disclosed is a method for administering a functional material to a human or animal subject in need thereof, the method comprising applying to the subject a composition comprising a film or a plurality of film fragments entrained in a carrier, wherein the film comprises the functional material.

First claim

What is claimed is:

1. An oral care composition comprising a film entrained in a carrier, wherein said film comprises a film forming polymer and a functional material, and wherein said carrier comprises a gel, a colloid, or a fibrillar network comprising from about 5% to about 95% water, wherein said film has a Dissolution Value from about 2 to about 200 seconds and is operable to effect release of said functional material during use of said composition.

2. A composition according to claim 1 , wherein the polymer is selected from the group consisting of water-soluble polymers, water-dispersible polymers, water-insoluble polymers, and mixtures thereof.

3. A composition according to claim 1 , wherein the polymer is a water-soluble polymer.

4. A composition according to claim 3 , wherein said water-soluble polymer is selected from the group consisting of water-soluble cellulose ethers, polyvinylpyrollidone, and mixtures thereof.

5. A composition according to claim 1 , wherein the polymer is a cellulose ether.

6. A composition according to claim 1 , wherein said carrier comprises an active material.

7. A composition according to claim 6 , wherein said composition is an oral care composition and said active material is selected from the group consisting of abrasives, anticaries agents, tartar control agents, antiplaque agents, periodontal actives, breath freshening agents, malodour control agents, whitening agents, and combinations thereof.

8. A composition according to claim 1 , wherein said functional material is a therapeutic active.

9. A composition according to claim 8 , wherein said therapeutic active is selected from the group consisting of abrasives, anticaries agents, tartar control agents, antiplaque agents, periodontal actives, breath freshening agents, malodour control agents, whitening agents, stain prevention actives, salivary stimulants, and combinations thereof.

10. A composition according to claim 1 , wherein said functional material is a flavorant.

11. A composition according to claim 1 , wherein said film comprises a compatibility enhanced active.

12. A composition according to claim 11 , wherein said carrier is suitable for use in a dentifrice, and said compatibility enhanced active is selected from the group consisting of cationic antimicrobials, calcium salts, fluoride salts, proteins, and mixtures thereof.

13. A composition according to claim 1 , wherein said film comprises a controlled release composition comprising said functional material.

14. A composition according to claim 13 , wherein said controlled release composition is operable to sustain release of said functional material through the use of said composition.

15. A composition according to claim 1 , wherein said film has a Dissolution Value of at least 5 seconds.

16. A composition according to claim 15 , wherein said film comprises a plurality of first film fragments having a first Dissolution Value, and a second plurality of second film fragments having a Dissolution Value that is significantly different than said first Dissolution Value.

17. A composition according to claim 1 , wherein said composition comprises a plurality of film fragments.

18. A composition according to claim 17 wherein said fragments are substantially lamellar, having a thickness of from about 0.1 mils to about 10 mils.

19. A composition according to claim 17 , wherein said fragments have a length of at least 0.2 mm.

20. A composition according to claim 17 , wherein said fragments have a length of up to 10 mm.

21. A composition according to claim 17 , wherein said film fragments have an aspect ratio of at least 5:1 to about 500:1.

22. A composition according to claim 17 , wherein said fragments are visibly discernable.

23. A composition according to claim 22 , wherein said fragments are of a repeating shape.

24. A composition according to claim 23 , wherein said shape is substantially square.

25. A composition according to claim 17 , wherein said film comprises a plurality of first fragments and a plurality of second fragments, wherein said first fragments have a shape different than said second fragments.

26. A composition according to claim 1 , wherein said film comprises a colorant.

27. A composition according to claim 17 , wherein said film comprises a plurality of first film fragments having a first color, and a plurality of second film fragments having a second color that is significantly different than said first color.

28. A composition according to claim 1 , wherein said film comprises a plurality of layers.

29. A composition according to claim 28 , wherein said film comprises a polymeric film and a coating on at least one surface of said film.

30. A composition according to claim 22 , wherein said fragments have a refractive index different than the refractive index of said carrier.

31. An oral care composition comprising a carrier having distributed therein a plurality of lamellar fragments, wherein said fragments comprise a matrix and a functional material, and wherein said carrier comprises a gel, a colloid, or a fibrillar network comprising from about 5% to about 95% water, wherein said fragments have a Dissolution Value from about 2 to about 200 seconds and are operable to effect release of said functional material during use of said composition.

32. A composition according to claim 31 , wherein said matrix comprises a material selected from the group consisting of film forming materials, clays, waxes, and mixtures thereof.

33. A composition according to claim 31 , wherein said matrix comprises a film forming material selected from the group consisting of water-soluble polymers, water-dispersible polymers, water-insoluble polymers, and mixtures thereof.

34. A composition according to claim 31 , wherein said functional material is a therapeutic active.

35. A composition according to claim 31 , wherein said functional material is flavorant.

36. A composition according to claim 31 , wherein said fragments comprise a compatibility enhanced active.

37. A composition according to claim 36 , wherein said carrier is suitable for use in a dentifrice, and said active is selected from the group consisting of cationic antimicrobials, calcium salts, fluoride salts, proteins, and mixtures thereof.

38. A composition according to claim 31 , wherein said fragments have a Dissolution Value of about 5 to about 100 seconds.
