Abstract

The personal care compositions of the present invention are in the form of an Article comprising a dissolvable fibrous web structure. The fibers of the dissolvable fibrous web structure comprise a surfactant; a water soluble polymeric structurant; and a plasticizer. Additionally the ratio of the water soluble water soluble polymeric structurant to the active agent in the fiber is 3.5 or less.

First claim

What is claimed is:

1. An oral care composition comprising:
(a) at least one layer of a nonwoven fibrous web structure comprising a water soluble polymer, and
(b) sugar alcohol,
wherein the oral care composition is an oral care article.

2. The oral care composition of claim 1 , wherein the composition further comprises a first surfactant.

3. The oral care composition of claim 1 , wherein the composition further comprises an active agent.

4. The oral care composition of claim 2 , wherein the composition further comprises a second surfactant.

5. The oral care composition of claim 1 , wherein the oral care article is a teeth cleaning article, teeth whitening article, tooth care article, periodontal gum care article, denture cleaning article, tongue cleaning article, breath freshening article, fluoride containing article, mouth rinse article, anti-cavity article, or a combination thereof.

6. The oral care composition of claim 1 , wherein the water soluble polymer comprises a polyvinyl alcohol, polyacrylate, polymethacrylate, copolymer of acrylic acid and methyl acrylate, polyvinylpyrrolidone, polyalkylene oxide, starch, starch derivative, pullulan, gelatin, hydroxypropylmethylcellulose, methycellulose, carboxymethycellulose, or a combination thereof.

7. The oral care composition of claim 2 , wherein the first surfactant comprises an anionic surfactant, a zwitterionic surfactant, or a combination thereof.

8. The oral care composition of claim 2 , wherein the first surfactant comprises an alkyl sulfate, alkyl ether sulfate, sulfated monoglyceride, sulfonated olefin, alkyl aryl sulfonate, primary, alkane sulfonate, secondary alkane sulfonate, alkyl sulfosuccinate, acid taurate, acid isethionate, alkyl glycerylether sulfonate, sulfonated methyl ester, sulfonated fatty acid, alkyl phosphate, acyl glutamate, acyl sarcosinate, alkyl lactylate, anionic fluorosurfactant, sodium lauroyl glutamate, or a combination thereof.

9. The oral care composition of claim 2 , wherein the first surfactant comprises a sodium laureth sulfate.

10. The oral care composition of claim 2 , wherein the first surfactant comprises a betaine.

11. The oral care composition of claim 2 , wherein the sugar alcohol comprises a polyhydric alcohol with from two to eight carbon atoms.

12. The oral care composition of claim 4 , wherein the second surfactant comprises an amphoteric surfactant, a nonionic surfactant, a cationic surfactant, a zwitterionic surfactant, or a combination thereof.

13. The oral care composition of claim 12 , wherein the nonionic surfactant comprises polyethylene glycol.

14. The oral care composition of claim 12 , wherein the zwitterionic surfactant comprises betaine.

15. The oral care composition of claim 12 , wherein the cationic surfactant comprises quaternary ammonium salt.

16. The oral care composition of claim 12 , wherein the cationic surfactant comprises cetylpyridinium chloride.

17. The oral care composition of claim 1 , wherein the oral care article comprises a liquid composition and at least two layers of a nonwoven fibrous web structure.

18. The oral care composition of claim 17 , wherein at least a portion of the liquid composition is between the at least two layers of a nonwoven fibrous web structure.

19. The oral care composition of claim 17 , wherein the liquid composition is water-releasable.

20. The oral care composition of claim 1 , wherein the oral care composition comprises a high surface area particle.

21. The oral care composition of claim 20 , wherein the high surface area particle comprises an amorphous silica, amorphous silica gel, precipitated silica, fumed silica, alumina, silicate, carbonate, or a combination thereof.

22. An oral care article comprising:
(a) at least one layer of a nonwoven fibrous web structure comprising a water soluble polymer,
(b) a first surfactant comprising anionic surfactant, a zwitterionic surfactant, or a combination thereof, and
(c) a second surfactant.

23. The oral care article of claim 22 , wherein the first surfactant comprises an alkyl sulfate, alkyl ether sulfate, sulfated monoglyceride, sulfonated olefin, alkyl aryl sulfonate, primary, alkane sulfonate, secondary alkane sulfonate, alkyl sulfosuccinate, acid taurate, acid isethionate, alkyl glycerylether sulfonate, sulfonated methyl ester, sulfonated fatty acid, alkyl phosphate, acyl glutamate, acyl sarcosinate, alkyl lactylate, anionic fluorosurfactant, sodium lauroyl glutamate, or a combination thereof.

24. The oral care article of claim 22 , wherein the first surfactant comprises alkyl sulfate, betaine, or combinations thereof.

25. The oral care article of claim 22 , wherein the second surfactant comprises an amphoteric surfactant, a nonionic surfactant, a cationic surfactant, a zwitterionic surfactant, or a combination thereof.

26. The oral care article of claim 22 , wherein the second surfactant comprises polyethylene glycol, cetyl pyridinium chloride, or combinations thereof.

27. An oral article comprising:
(a) at least one layer of a nonwoven fibrous web structure comprising a water soluble polymer, and
(b) sugar alcohol.

28. The oral care article of claim 27 , wherein the sugar alcohol comprises a polyhydric alcohol with from two to eight carbon atoms.
