"COMPOSITIONS CONTAINING A POLYONDENSATE COMPRISING AT LEAST ONE POLYURETHANE AND / OR POLYUREA UNIT AND A SILICONE WHICH - COMPRISES AT LEAST ONE CARBOXYLIC FUNCTION" DESCRIPTION OF THE INVENTION The invention relates to hair compositions comprising, in a cosmetically acceptable medium , a polycondensate comprising at least one polyurethane and / or li-urea unit and a silicone comprising at least one carbo-xl function. It also refers to a process for the shaping or maintenance of the hairstyle comprising the realization of these compositions as well as their use -for the manufacture of hair products, with a view to obtaining a maintenance or shaping of the hairstyle. The fixation of the hairstyle is an important element of the - hair that consists in maintaining the conformation already made - or in shaping the hair and in fixing them simultaneously. The hair products for the conformation and / or the most widespread styling on the cosmetics market are spray compositions essentially constituted by a solution that is most often alcoholic or aqueous and by one or more materials, generally resins. Polymers, whose function is to form welds between the hair, called tam-bien fixing materials, mixed with various ethical adjuvants. This solution can be conditioned, for example, in a suitable aerosol container placed under pressure with the REF .: 119516 help of a propeller. The compositions intended for fixing and / or for maintaining the hairstyle sometimes have the disadvantage of altering the cosmetic properties of the hair. Thus the hair can become rough and lose its natural softness. Therefore, combing compositions which fix and / or maintain the hairstyle by providing good cosmetic properties are sought. DE 195 41 326 are known from combing stations distributed from an aerosol device which contain, in a hydroalcoholic medium, a polymer with polyurethane unit as a fixing polymer, and a propellant.

The composition according to the invention can be in the form of a lotion or a gel. It can be applied by spraying, from an atomizer or an aerosol. The conditioning in the form of an aerosol is especially practical for the user who obtains without difficulty a fairly homogeneous distribution of the product. However, this type of packaging has the disadvantage of causing a release of volatile organic compounds (VOC) harmful to the environment. They come in particular from the amount of organic solvent used and the propellant gas chosen to make the composition. There is thus a very particular interest in the realization of cosmetic compositions conditioned in aerosol form for which the quantity of volatile organic compounds expelled is increasingly smaller. The quality of the spray obtained by means of an aerosol device, that is essentially the distribution of the droplets in the space at the outlet of the nozzle, depends strongly on the chemical constitution of the composition used.

According to the invention, "it is preferably used as propellant gas, a gas soluble or not in the composition such as dimethyl ether, fluorinated or non-fluorinated hydrocarbons, the usual liquefied gases or a mixture of these propellant gases. All the more advantageously, the dimethyl ether is advantageously used, the concentrations and the nature of the various components being chosen in order to decrease the contents of volatile organic compounds (VOC). -other side containing conventional cosmetic additives selected particularly among the fatty substances, the thickening agents, the softeners, the anti-foam agents, the moisturizing agents, the antiperspirant agents, the alkaline agents, the dyes, the pigments, the perfumes, surfactants, surfactants, hydrocarbon polymers-two, volatile or non-supplementary silicones, other than those described previously, proteins and vitamins. In particular, it may be advantageous to add other fixative polymers to the composition, such as non-ionic, anionic, cationic or amphoteric fixative polymers. The invention can be better understood with the help of the non-limiting example which follows and which constitutes an advantageous embodiment of the compositions according to the invention. -tion Example: The composition given below was made for which-percentages are percentages by weight. - Pol decontaminated polyester lactic acid / ethylene glycol P (MIS-EG) - dimethylol propanic acid (DMPA) - isoforonadi and société 4% - Silicone "Plus" Polymer VS 80 0.2% - Amino ethyl propane cs neutralization - Ethanol 15% - Dimethylether, 35% - 100% demineralised water It is noted that in relation to this date, the best method known by the applicant to carry out the aforementioned invention, is that which is clear from the present description.
