Extemporaneous care product based on a lyophilizate of microorganisms and surfactant(s) with an HLB greater than or equal to 12
First Claim
1. A lyophilizate obtained by lyophilization of a composition, the composition comprising:
- at least one live or inactivated physiologically acceptable microorganism, one of its metabolites, an extract thereof, or one of its fractions, at least one surfactant with an HLB greater than or equal to 12, and at least one lyophilization additive selected from the group consisting of polymers of natural origin,wherein the microorganism is selected from the group consisting of Lactobacillus johnsonii, Lactobacillus reuteri, Lactobacillus rhamnosus, Lactobacillus paracasei, Lactobacillus casei, Bifidobacterium bifidum, Bifidobacterium breve, Bifidobacterium longum, Bifidobacterium animalis, Bifidobacterium lactis, Bifidobacterium infantis, Bifidobacterium adolescentis, Bifidobacterium pseudocatenulatum, nonphotosynthetic filamentous bacteria, and mixtures thereof, andwherein the lyophilizate is in dry form,wherein the lyophilizate comprises a lyophilizate-redissolution effective amount of from 5 to 14% by weight of surfactant(s) with an HLB greater than or equal to 12, relative to the total weight of the said lyophilizate in the dry form,wherein the surfactant(s) with an HLB greater than or equal to 12 is selected from the group consisting of alkyl and polyalkyl esters of poly(ethylene oxide), alkyl and polyalkyl esters of sorbitan, optionally polyoxyethylenated, alkyl and polyalkyl glucosides and polyglucosides, alkyl and polyalkyl esters of glycerol, optionally polyoxyethylenated, alkyl ether sulphates, sarcosinates, betaines and mixtures thereof;
wherein the microorganism, metabolite, extract and/or fraction thereof is formulated in a quantity equivalent from 0.1% to 50% of active material or dry matter, of the lyophilized formula or support containing the microorganism, metabolite, extract and/or fraction thereof;
wherein the lyophilization additive is present in an amount of from 0.5% to 5% by weight relative to the total weight of said lyophilizate, andwherein the lyophilizate comprises at least one cryoprotectant.

Abstract
The present invention relates to a method for the cosmetic treatment of a keratin material comprising at least the steps of: (a) having available a lyophilizate containing at least one live or inactivated, physiologically acceptable microorganism, one of its metabolites or one of its fractions and at least one surfactant with an HLB greater than or equal to 12, (b) having available a physiologically acceptable medium, separate from the said lyophilizate, (c) bringing the said lyophilizate extemporaneously into contact with the said medium under conditions favorable for the solubilization and/or dispersion of the said lyophilizate in the said medium, and (d) bringing the mixture obtained in the preceding step into contact with the said keratin material. It further relates to a lyophilizate as defined above.
