Abstract

The present invention relates to a composition which is in the form of a water-soluble anhydrous film comprising at least one water-soluble or water-dispersible film-forming polymer, and at least one live, in particular probiotic, microorganism. It also relates to a kit containing such a composition, as a combination with a secondary composition.

Claims

1. A composition which is in the form of a water-soluble anhydrous film comprising (i) at least one water-soluble or water-dispersible film-forming polymer, and (ii) at least one live, in particular probiotic, microorganism, and comprising at least one oxyalkylenated polydimethylsiloxane derivative.

2. The composition as claimed in claim 1, the film of which has a thickness of from 10 μ

m to 1000 μ

m.

3. The composition as claimed in claim 1 containing less than 15% by weight of water.

4. The composition as claimed in claim 1, in which the film-forming polymer has a solubility in water, measured at 25°

C., at least equal to 0.1 g/liter.

5. The composition as claimed in claim 1, in which the film-forming polymer is selected from the group consisting of vinyl polymers, cellulosic derivatives, starches and their derivatives, optionally modified polymers of natural origin, polymers derived from chitin or from chitosan, protein polymers, acrylic phosphorylcholin copolymers and anion-cation complexes, and mixtures thereof.

6. The composition as claimed in claim 1, in which the film-forming polymer is selected from the group consisting of vinyl polymers and cellulosic derivatives, and mixtures thereof.

7. The composition as claimed in claim 6, in which the film-forming polymer is selected from the group consisting of polyvinyl acetate, hydroxypropylcellulose and hydroxypropylmethylcellulose, and mixtures thereof.

8. The composition as claimed in claim 1, in which the amount of film-forming polymer(s) ranges from 10% to 95% by weight relative to the total weight of the composition.

9. The composition as claimed in claim 1, in which said microorganism is selected from the group consisting of ascomycetes such as Saccharomyces, Yarrowia, Kluyveromyces, Torulaspora, Schizosaccharomyces pombe, Debaromyces, Candida, Pichia, Aspergillus and Penicillium, and bacteria of the genus Bifidobacterium, Bacteroides, Fusobacterium, Melissococcus, Propionibacterium, Enterococcus, Lactococcus, Staphylococcus, Peptostrepococcus, Bacillus, Pediococcus, Micrococcus, Leuconostoc, Weissella, Aerococcus, Oenococcus or Lactobacillus, and mixtures thereof.

10. The composition as claimed in claim 1, in which said microorganism is a probiotic microorganism.

11. The composition as claimed in claim 10, in which said probiotic microorganism is selected from the group consisting of lactic acid bacteria, bifidobacteria, yeasts and sporulated bacteria, and mixtures thereof.

12. The composition as claimed in claim 11, in which said probiotic microorganism comprises at least one microorganism of the Lactobacillus or Bifidobacterium group.

13. The composition as claimed in claim 12, in which the microorganism is selected from the group consisting of Lactobacillus johnsonii, Lactobacillus reuteri, Lactobacillus rhamnosus, Lactobacillus paracasei, Lactobacillus casei or Bifidobacterium bifidum, Bifidobacterium breve, Bifidobacterium longum, Bifidobacterium animalis, Bifidobacterium lactis, Bifidobacterium infantis, Bifidobacterium adolescentis or Bifidobacterium pseudocatenulatum, and mixtures thereof.

14. The composition as claimed in claim 1, comprising from 10-1 cfu/g to 1015 cfu/g of live microorganism(s).

15. The composition as claimed in claim 1, comprising at least one probiotic microorganism combined with at least one live microorganism of skin flora and/or a nonphotosynthetic filamentous bacterium or one of its extracts.

16. The composition as claimed in claim 1, also comprising at least one polysaccharide thickener.

17. A kit for formulating a cosmetic product, comprising:

(i) at least a first composition referred to as A as defined in claim 1, and

(ii) a second composition referred to as B, comprising at least one physiologically acceptable medium.

18. The kit as claimed claim 17, in which the product is for oral administration.

19. The kit as claimed in claim 17, in which the product is for topical application.

20. The kit as claimed claim 17, in which the second composition contains at least one liquid fatty phase.

21. The kit as claimed in claim 17, in which the second composition is in the form of an emulsion.

22. The kit as claimed in claim 17, in which the second composition comprises at least one compound selected from the group consisting of thickeners, gelling agents, emulsifiers, dyestuffs and/or organic or inorganic fillers.

23. The kit as claimed in claim 19, in which the second composition comprises at least one active agent having a cosmetic or dermatological application.

24. A cosmetic product obtained by incorporating at least one composition as defined in claim 1 into a second composition comprising at least one physiologically acceptable medium.

25. A process for cosmetic care of keratin materials, comprising the topical or oral administration of a product as defined in claim 17.
