Definitions

• the present invention relates to cosmetic use for the treatment of keratin materials of at least one hydrophobin, as well as to the compositions and methods for cosmetic treatments of the skin and / or hair.
• Cosmetic products intended for hair treatments and bringing properties to the hair such as styling, shine, disentangling, mainly use polymers which adsorb weakly on the hair or which adsorb well but giving a charged touch, generally sticky.
• the cosmetic effects observed are not lasting because the polymers are quickly eliminated in shampoos.
• hydrophobins can be used to treat the surface of keratin materials in order to obtain a cosmetic deposit which resists several or shampoos.
• the subject of the invention is therefore the cosmetic use for the treatment of keratin materials of a composition containing at least one hydrophobin.
• Another object of the invention is the cosmetic compositions used.
• Another object of the invention is a cosmetic treatment process for the skin and / or the hair using hydrophobin.
• Other objects of the present application will emerge on reading the description and the examples which follow.
• the cosmetic use which constitutes a first object of the invention comprises the use for the treatment of keratin materials in particular the hair of a composition containing in a cosmetically acceptable medium of at least one hydrophobin.
• hydrophobins used in accordance with the invention are the natural hydrophobins obtained by extraction, the hydrophobins obtained by synthesis or hydrophobins modified by chemical reaction by methods known to those skilled in the art (Bioconjugate Techniques, Académie. Press 1996).
• hydrophobins carrying cosmetic active agents such as dyes, sunscreens, polymers, bactericidal agents. These agents are fixed by grafting and formation of a covalent bond. These modifications can also relate to the replacement, omission or incorporation of one or more amino acids, provided that at least the adsorption property characteristic of hydrophobins is maintained, these products being obtainable by genetic engineering. Hydrophobins can also be covalently attached to supports such as mineral or organic particles.
• the hydrophobins used according to the invention are small proteins of approximately 100 amino acids secreted by filamentous fungi and which fulfill a large number of functions in the growth and development of these fungi.
• hydrophobins can be separated into two classes: class I and class II. The characteristics of these two classes of hydrophobins are described in the article by
• hydrophobin of class II mention may be made of the hydrophobin of cerato-ulmine or of cryparin. We prefer the use of class I hydrophobins and among them, SC3 or SC3P.
• SC3 is a glycosylated hydrophobin of 112 amino acids from the common Schizophyllum fungus.
• compositions used according to the invention preferably comprise from 10 ppb to 20% and in particular from lppm to 10% by weight by weight of at least one hydrophobin relative to the total weight of the composition
• compositions comprise from 5 ppm to 5% by weight of at least one hydrophobin relative to the total weight of the composition.
• compositions of the present invention may contain, in addition to the hydrophobin, at least one polysaccharide and / or at least one cosmetic active.
• the polysaccharide can be extracted from the culture medium of the fungus which produces it, together with the hydrophobin or isolated separately and added later. It can also come from another natural or synthesized strain.
• the polysaccharide used in the composition according to the invention is schizophyllane.
• Schizophyllane is a simple branched glucan, in which the repeated unit consists of three molecules of D-glucose linked in ⁇ 1-3, one of them being linked to a molecule of D-glucose by a link ⁇ 1 -6.
• compositions according to the invention preferably comprise from Oppb to
• compositions comprise lppm at 10% by weight of at least one polysaccharide relative to the total weight of the composition. Even more preferably, the compositions comprise from 5 ppm to
• the cosmetic compositions according to the invention can also comprise hydrophobin mixed with one or more cosmetic active agents.
• the cosmetic active agent (s) included in the compositions according to the invention can be chosen from the group composed of soluble natural or synthetic polymers, insoluble natural or synthetic polymers, pigments, hydrating agents, anti-dandruff agents, vegetable, animal or synthetic oils, waxes animal or vegetable such as ceramides, proteins, enzymes, mineral, metallic or organic particles, vitamins, sunscreens, dyes, perfumes or antioxidants.
• compositions of the invention can also comprise surfactants in the same proportions.
• the surfactants and polymers can be of nonionic, cationic, anionic or amphoteric nature. We can also add preservatives.
• the cosmetically acceptable medium consists of water or a mixture of water and solvent.
• This solvent can be a lower C1-C4 alcohol such as ethanol or isopropanol or a polyol or a polyol ether such as glycerin, polypropylene glycol or their ethers.
• compositions according to the invention contain between 0 and 50% of one or more solvents.
• compositions in accordance with the invention can be in the form of an aqueous alcoholic or hydro-alcoholic solution, a lotion, a dispersion, a fluid or thick cream, a gel, a stick , emulsion or foam. They can optionally be packaged in an aerosol device.
• Another object of the invention is a cosmetic treatment process for the skin and / or hair which consists in applying, at a temperature between 10 and 100 ° C. to the keratin materials in sufficient quantity, a composition according to the invention, this application being followed or not by rinsing and / or drying at room temperature or under heat.
• keratin material within the meaning of the present invention means the skin, hair, eyelashes, nails and body hair.
• the compositions according to the invention are applied to the hair.
• a variant consists in applying the composition containing at least one hydrophobin, then in following this application by a treatment based on a surfactant composition at room temperature or under heat.
• a composition containing either a reducing agent or an oxidizing agent for the permanent deformation of the hair, an oxidation coloring, bleaching, a shampoo or a styling composition may be applied to the hair.
• the hair treatment method according to the invention can also consist of the application of the cosmetic composition according to the invention, after treatment of the hair fiber with a cosmetic active agent.
