(54) Title: COSMETIC COMPOSITION BASED ON A SUPRAMOLECULAR POLYMER AND A SILICONE ELASTOMER (57) Abstract: The present invention relates mainly to a cosmetic composition and in particular a composition for making up and/ or caring for the skin and/or the lips, comprising at least one supramolecular polymer and an organopolysiloxane elastomer. The present invention relates mainly to a cosmetic composition and in particular a composition for making up and/or caring for the skin and/or the ps, comprising at. least one supramolecular polymer and an organopolysiloxane elastomer. n general, when women use a makeup product, especially of foundation or lipstick type, they wish this product to have, after application, good remanence on the skin or the lips, and in particular not to he transferred. With regard to this expectation, one or more polymers that are specifically dedicated towards affording these improved remanence properties over time are commonly introduced into compositions of this type illustrations of these polymers that may particularly be mentioned include silicone resins, polyacry tes and latices. However, the abovementioned polymers, which are advantageous in terms of remanence and transfer-resistance properties, are unfortunately liable to give rise to discomfort sensations, during application (difficult spreading, tackiness) and/or after application (tautness, mask effect) of the cosmetic product containing them. Supramolecular polymers such as those described in patent applications EP 2 9 15 1 and FR 2 938 758 are, on the other hand, known for allowing the production on th skin and/or the lips a deposit that is both comfortable and endowed with good properties in terms of improved remanence over time, in particular of remanence of the colour of the deposit (no embrittlement or fragmentation of the deposit, which re ains uniform). There remains, however, a sensation of "tackiness" for the user during application and drying on the skin and/or the lips of prod cts incorporating these supramolecular polymers. Unexpectedly, the inventors have found that it proves to be possible to overcome this drawback provided that such supramolecular polymers are used in combination with an organopolysiloxane elastomer. The aim of the present invention is especially to overcome this drawback and to propose a cosmetic composition that can, on the one hand, afford good cosmetic properties such as good adhesion to the support (skin) and thus good remancnce of the composition, where appropriate, good sheen, and that can, on the other hand, form a non- tacky or sparingly tacky deposit that is particularly resistant to external attack by fatty substances (oil, meals or sebum) and to friction, resulting in less wear of the deposit. Thus, according to one of its aspects, the present invention relates to a cosmetic process or making up and/or caring for the skin and/or the lips, comprising at least the application to the said skin and/or the said ip s of a composition comprising, in a physiologically acceptable medium, at least one supramolecuiar polymer, at least one organopolysil oxane elastomer and at least one fatty phase. For the purposes of the present invention, the term "physiologically acceptable inedium" is intended to denote inedium that is suitable for applying a composition to the skin and/or the lips. Advantageously, the compositions under consideration according to the invention are anhydrous or contain less than 3% by weight of water and preferably ess tha 1% by weight of water relative to d e total weight of the composition. The term "anhydrous" especially means that water is preferably not deliberately added to the composition but may be present in trace amount in the various compounds used in the composition. According to certain embodiments, it may be envisaged for the compositions according to the invention and used in the processes according to the invention to be t ee of ethanoi. As emerges from the examples below, the combination under consideration according to tl e invention proves to be most particularly effective for affording the composition applied to the skin or the lips improved remanence over time, i particular remanence of the colour of the deposit (no e britt ent or fragmentation of the deposit, which remains homogeneous) and satisfactory comfort properties, both on application and during wearing (no sensation of tackiness, or sensation of tautness or dryness, especially reduction of the tack o drying and, in certain embodiments, a transfer-resistance effect). What is more, in the ease of foundations, its transfer-resistance properties are moreover significantly improved. This particular embodiment may especially allow access to compositions especially makeup compositions, whose deposits on keratin materials, and in particular the skin and/or the lips, is uniform and/or non-tacky or sparingly tacky. Such a deposit may especially afford a sensation of comfort to the wearer (softness, glidance of the deposit formed). n addition, such a composition may have improved properties in terms of transfer resistance, remanence of the deposit, especially in terms of colour (no embrittlement or fragmentation of the deposit, which remains uniform and/or resistant to friction), and of resistance to fats. According to another of its aspects, the present invention relates to a anhydrous composition for making up and/or caring for the ski and/or the lips, compri sing in a physiologically acceptable medium, at least one supramolecular polymer, at least one silicone e stomer and at least one fatty phase. The compositions under consideration according to the invention may be in solid or liquid form at 2 ) C. For the purposes of the invention, the term "solid" characterizes the state of the composition at a temperature of 20°C. In particular, a solid composition according to the invention has, at a temperature of 20°C and at atmospheric pressure (760 mraHg), a hardness of greater than 30 N and preferably greater than 40 Mm 4 . As developed below in a particular variant of the invention, the cosmetic process for making up and/or caring for the ski and/or the ps according to the invention may also comprise an additional step consisting in artificially accelerating the drying of the deposit of the composition simultaneously with or subsequent to its application, by exposure of said deposit to blown air having a temperature ranging from 35 to 45 °C. Protocol for r e s ri the hardness The hardness of a composition especially of lipstick wand type is measured according to the following protocol: The stick of lipstick is stored at € for 24 hours before measuring the hardness. The hardness may be measured at 20°C via the "cheese wire" method, which consists in transversely cutting a wand of product, which is preferably a circular cylinder, by means of rigid tungsten wire 250 µπ in diameter, by moving the wire relative to the stick at a speed of 00 mm/minute. The hardness of the samples of compositions of the vention, expressed in Nm is measured using a DFGHS2 tensile testing machine from the company mdelco- Chati!lon.
