The present invention relates to a method for making up and / or caring for the skin and / or the lips comprising applying to the skin and / or the lips of a cosmetic composition and in particular a make-up and / or care composition skin and / or lips comprising at least one supramolecular polymer and a silicone compound having a viscosity of less than 10,000,000 cSt at 25 ° C. The present invention also relates to the compositions used according to this process. In general, when women use a make-up product, especially of the foundation or lipstick type, they wish that this product has, after application, a good hold on the skin or the lips, whether it is not very sticky and in particular that it does not transfer. In view of this expectation, it is commonly introduced in this type of compositions one or more polymers specifically dedicated to provide these improved properties withstanding time. As an illustration of these polymers, silicone resins, polyacrylates and latices may be particularly mentioned. However, the abovementioned polymers, which are advantageous in terms of holding properties, and in particular of non-transfer, are unfortunately likely to generate a feeling of discomfort, during application (difficult spreading, stickiness) and / or after application (tightness). mask effect), of the cosmetic product containing them.

Supramolecular polymers such as those described in documents EP2189151 and FR2938758 are, however, known to allow obtaining on the skin or the lips a deposit which is both comfortable and has good properties with improved resistance over time, in particular of keeping the color of the deposit (no embrittlement or fragmentation of the deposit which remains homogeneous). There remains, however, a feeling of "sticky" for the user during application and drying on the skin or lips of the products incorporating these supramolecular polymers. In addition, deposits formed from a pharmaceutical formulation incorporating such a supramolecular polymer may be provided with insufficient mechanical strength. Unexpectedly, the inventors have found that it is possible to overcome this disadvantage provided that such supramolecular polymers are used in combination with at least one silicone compound having a viscosity of less than 10,000,000 cSt at 25 ° C.

Thus, the present invention aims to overcome this disadvantage and to provide a cosmetic composition, on the one hand, to obtain good cosmetic properties such as good adhesion to the support (skin or hair) and therefore good keeping the composition, if necessary, a good gloss, and secondly, capable of forming a deposit that is not or slightly tacky and particularly resistant to external aggression by fatty substances (oil, meals, sebum) as well as friction, resulting in less wear of the deposit.

Non-transfer evaluation protocol The forearm is cleansed with a non-greasy make-up remover (Lancôme Effacil type) and then with a cotton of water. After 5 minutes, a foundation formula of one of Examples 5 to 13 is applied to the finger on the forearm. The amount applied is 0.05g over an area of 5cm by 5cm. 10 minutes after the application, a Kleenex is passed 5 times on the forearm, for this the Kleenex is folded in four, it is placed with a rather strong pressure on the skin at one end of the deposit of Fond de dyed then moved on the forearm quite slowly towards the other end. The amount of foundation of complexion that has transferred to the kleenex is then evaluated.

Examples 15 and 16 of cosmetic formulas of the type of foundation fluid emulsion: Two basic formulas were prepared of liquid complexion having the following composition (a composition in accordance with the invention and a comparative composition) Table 6 Formula 15 Formula 16 According to the Comparative Invention Excluding Invention Al Polymer Solution 50 (ie 12.5% of 50 (ie 12, 5% supramolecular GI2000 dry matter) of dry difunctionalized material) 25% ureidopyrrimidone in isododecane as prepared in Example 2 Isododecane 2% 3% A2 PEG-30 dipolyhydroxystearate 2.5 2.5 (CITHROL DPHS-SO- (MV), Croda) A3 Isododecane 2.5 2.5 Pigments 10 10 B Water 29.5 29.5 Preservatives 0.5 0.5 C Silicon microspheres 2 2 amorphous (particle size: 3 microns) (Miyoshi Kasei, Sunsphere H- 33, AGC Si-TECH) Dimethicone 60,000cst (Belsil 1 DM60000, Wacker) Total 100 100 Procedure: The constituents of phase Al are weighed in a beaker with Moritz stirring while maintaining the ambient temperature at 50 ° C. Phase A2, previously melted, is then added while maintaining stirring. Phase A3 is prepared separately by grinding the pigments with a three-roll mill and then is added with stirring to the above mixture. To prepare phase B, the water is boiled and then the other components of phase B are added. The temperature of phase B is returned to 50 ° C. The emulsion is at 50 ° C. The two phases must have a temperature close to 50 ° C. The aqueous phase B is slowly poured into phase A, increasing as the stirring speed of the Moritz increases to 2500 rpm. After addition, stirring is continued for 10 minutes at room temperature. Phase C is then added and the mixture is stirred for 5 minutes. Phase D is then added and the mixture is stirred for 5 minutes.

Each of the formulations thus obtained is then evaluated in terms of non-transfer and reduction of the tack after application according to the protocols described above. Table 7 below reports on the transfer results.

Table 7 Formula 15 according to Formula 16 the Comparative Invention Comprising 1% PDMS 60,000 cSt Evaluation + ++++ of the Transfer It follows from these results that the deposition carried out with the composition according to the invention shows an ability to transfer significantly lessened compared to the deposit made with the comparative composition 16. This composition also leads to obtaining a deposit for obtaining a skin feel softer, more slippery and less tacky. In addition, the composition of Example 15 leads to a deposit, so that the adhesive decreases after application (during the drying phase).

Table 8 below reports the results regarding the decrease of the tackiness during drying: Table 8 Compositions Formula 15 according to Formula 16 1% Comparative PDMS 60,000 cst Evaluation of ++ ++++ Tight From these results, the deposit formed from the composition according to the invention exhibits a tackiness significantly lower in comparison with the deposit formed from the comparative composition.
