Description

AQUEOUS COMPOSITION COMPRISING A SULPHONATED POLYESTER AND POLYURETHANE Field of the Invention The present invention relates to a new, particularly topical, smoke composition, comprising a particular hydrophilic gelling agent of the suifed polyester type and a fumaric radical polymer, intended in particular for the cosmetic and / or dermatological fields. The invention also relates to the use of this composition for the make-up or the cosmetic treatment of the keratin materials of the human being such as the skin, nails, eyelashes, eyebrows, hair, or mucous membranes such as the lips. This composition may be in the form of a gel, a paste or a molten product, in particular a bar.

BACKGROUND OF THE INVENTION Make-up or treatment products of the skin or of the lips such as background or red lip make-ups generally contain fatty phases such as waxes and eff .; 31106 oils, pigments and / or fillers and, optionally, additives such as cosmetic or dermatological active agents. They may contain gelling agents that make it possible to obtain the desired consistency for the composition according to its application.

BRIEF DESCRIPTION OF THE INVENTION These compositions, when applied to the skin or lips, have the drawback of transferring, that is to say deposited at least in part, "leaving marks, on some supports with which they can be put in contact, and particularly a glass, a cup, a cigarette, a garment or the skin.It happens a mediocre persistence of the applied film, which needs to renew regularly the application of the composition 'of background makeup or of red lips. of these unacceptable markings on blouse collars can deter some women from using this type of makeup It is known from patent application EP-A-602905 to associate volatile oils with waxes to obtain products having improved non-transfer properties However, these products slip in their application on keratin materials, such as the lips, making their application It is difficult to control. In addition, these products leave an impression of tightness during and after their application on the lips. On the other hand, the compositions after application to the skin or lips may be removed on contact with water, particularly during bathing or with contact with rain or tears. It is therefore desirable to have compositions that have good remanence properties to water.

The inventors have discovered that such a composition could be obtained by using a particular hydrophilic gelling agent of the sulfonated polyester type and a polymeric system containing a radical polymer. A composition is then obtained which leaves after application a film which exhibits a good performance, does not transfer anything, and is resistant to water. The film is particularly bright, non-adhesive and comfortable (without tightness) during and after application of the composition on keratin materials. The film also produces a feeling of freshness and is easy to remove make-up with the make-up removers commonly used. In addition, the composition is less slippery than the non-transfer products containing volatile oils, thus facilitating its application on keratin materials. The present invention has puffs for the purpose of a novel smoke composition comprising, in an aqueous phase, a hydrophilic gelling agent of sulfonated type., characterized in that the hydrophilic gelling agent is a hydrosoluble or water dispersible terephthalic copolyester oiigomer and in that the composition also comprises a polymeric system containing radicary polymer particles dispersed in the aqueous phase, a) The terephthalic copolyester ether: The gelling agents Particularly used according to the invention are water-soluble or water-dispersible terephthalic copolymer terephthalic oligomers comprising essentially repeating dicarboxylate units of formula (I): [-CO-A-CO-O- (CH2-CH20) "-] (I) wherein - A represents a group 1, phenylene, 1,3-sulphonophenium and optionally 1,3-phenylene, n ranges from 1 to 4, with at least 35% by mole of the said units of formula (I) ) units of formula (I) for which A represents a 1,4-phenylene group and n is equal to 1, with at least 7% by mole of the said units of formula (I) units of formula (I) for wherein A represents a 1,3-sulfophenylene group, the molecular mass by weight of the said oligomers being less than 20,000, preferably less than 15,000.

When all the "diacid" monomers are used in the form of a diester, the operation of transeserification (exchange) between these "diacid" monomers and the ethylene glycol is carried out at a temperature greater than or equal to 130 ° C, preferably of the order from 140 to 220 ° C and very particularly in the order of 180 to 220 ° C; at this temperature the methanol (preferred case of the methyl disters) formed is removed from the reaction medium preferably by distillation.

The vacuum is then broken with nitrogen, and the polymer is poured into an ingot mold; after cooling, the polymer shreds. When one of the "diacid" monomers is present in the form of a diacid or anhydride and the others are in the form of a diester (s), the indicated copolyester oligomers are obtained by first performing a transesterification operation of the diester monomers with ethylene glycol under the conditions described above, followed by an esterification operation in the medium of diacid or anhydride monomers with ethylene glycol, then polycondensation under the conditions described above, distributing the total amount of ethylene glycol between the two operations (transesification and esterification) .

The operation is carried out in the presence of the same types of catalyst and etherification limiter as those used during the transesterification operation, and this in the same proportions. The reaction is carried out with the elimination of water which is transferred from the reactor at the same time as excess polyol.
