Abstract: Process for making up and/or caring of the skin and/or lips, comprises: contacting the surface for applying first composition with a second liquid cosmetic composition comprising at least 50 wt.% of at least one 2-5C hydrocarbon alcohol; and applying the surface for applying first composition previously contacted with the second composition on the skin and/or lips, where the first solid cosmetic composition contains at least 5 wt.% of a polyamide comprising (i) hydrocarbon polyamides (Ia), and (ii) silicone polyamides, comprising at least one siloxane unit (I). Process for making up and/or caring of the skin and/or lips, comprises: contacting the surface for applying first composition with a second liquid cosmetic composition comprising at least 50 wt.% of at least one 2-5C hydrocarbon alcohol; and applying the surface for applying first composition previously contacted with the second composition on the skin and/or lips, where the first solid cosmetic composition contains at least 5 wt.% of a polyamide comprising (i) hydrocarbon polyamides of formula (R1-O[-C(=O)-R2-C(=O)-NR4-R3-NR4-] n-C(=O)-R2-C(=O)-O-R1) (Ia), and (ii) silicone polyamides, comprising at least one siloxane unit of formula (-[-G1a-X-[SiO(R4)(R6)-] m-SiR5R7-X-G-] n-) (I). R1 : 4-24C alkyl or 4-24C alkenyl; R2 : 4-42C hydrocarbon provided that 50% of the R2 groups represent 30-42C hydrocarbon group; R3 : an organic group provided with at least 2C, hydrogen atoms and optionally one or more oxygen or nitrogen atoms; R4 : H, 1-10C alkyl or a direct bond to R3 or R4 such that the nitrogen atom to which are linked to both R3 and R4 is part of a heterocyclic structure (R4-N-R3), with at least 50% of R4 representing H; G1a : C(O) (when G is -C(O)-NH-Y1-NH-), or -NH- (when G is -NH-C(O)-Y1-C(O)-); G : -C(O)-NH-Y1-NH- or -NH-C(O)-Y1-C(O)-; R4-R7 : , linear, branched or cyclic 1-40C hydrocarbon groups (optionally saturated, optionally containing in their chain one or more oxygen, sulfur and/or nitrogen atoms, and optionally partly or completely substituted by F), 6-10C aryl groups (optionally substituted with one or more 1-4C alkyl groups), or polyorganosiloxane chains optionally containing one or more oxygen, sulfur and/or nitrogen atoms; X : 1-30C alkylene di-yl group, optionally containing one or more oxygen and/or nitrogen atoms; Y1 : linear or branched a 1-50C divalent alkylene group, arylene, cycloalkylene, alkylarylene or arylalkylene, (optionally saturated and containing one or more oxygen, sulfur and/or nitrogen atom, and/or substituted by F, OH, 3-8C cycloalkyl, 1-40C alkyl, 5-10C aryl, phenyl optionally substituted with 1-3 groups of 1-3C alkyl, 1-3C hydroxyalkyl or amino-1-6Calkyl), or -T(R8)-; T : optionally saturated 3-24C trivalent or tetravalent hydrocarbon group (optionally substituted by a polyorganosiloxane chain, and containing one or more O, N or S), or a trivalent atom comprising N, P or Al; R8 : 1-50C alkyl group, or a polyorganosiloxane chain, which may include one or more ester, amide, urethane, thiocarbamate, urea, thiourea and/or sulfonamide which can be optionally linked to another polymer chain; and n : 2-500, preferably 6-200. An independent claim is included for multi-compartment device or kit for make up and/or care of skin and/or lips comprising at least a first compartment containing the first solid cosmetic composition containing at least 5 wt.% of a polyamide; and at least one second compartment comprising at least one second cosmetic liquid composition comprising at least 50 wt.% of at least one 2-5C hydrocarbon alcohol.
