1: A cosmetic composition comprising, in a cosmetically acceptable medium:
(a) a supramolecular compound obtained by reaction between:
at least one oil bearing at least one nucleophilic reactive group selected from the group consisting of OH and NH2, andat least one junction group capable of hydrogen bonding with one or more partner junction groups, each pairing of a junction group involving at least three hydrogen bonds, the junction group bearing at least one isocyanate or imidazole reactive group capable of reacting with the reactive group borne by the oil, the junction group also comprising a unit of formula (I) or (II):in which:
R1 and R3, which may be identical or different, represent a divalent carbon-based radical selected from the group consisting of (i) a linear or branched C1-C32 alkyl group, (ii) a C4-C16 cycloalkyl group and (iii) a C4-C16 aryl group; optionally comprising 1 to 8 heteroatoms selected from the group consisting of O, N, S, F, Si and P; and/or optionally substituted with an ester or amide group or with a C1-C12 alkyl radical; or a mixture of these groups; R2 represents a hydrogen atom or a linear, branched or cyclic, saturated or unsaturated, optionally aromatic, C1-C32 carbon-based radical, which may comprise one or more heteroatoms selected from the group consisting of O, N, S, F, Si and P; (b) at least two distinct non-volatile silicone oils selected from the group consisting of: i) a phenyl silicone oil of formula (II) or (VII) below:in which the groups R represent, independently of each other, saturated or unsaturated, linear, cyclic or branched C1-C30 radicals, at least one of the groups R being a phenyl group,in which:
R1 to R6, independently of each other, are saturated or unsaturated, linear, cyclic or branched C1-C30 radicals, m, n and p are, independently of each other, integers between 0 and 100, with the proviso that the sum n+m is between 1 and 100; ii) a linear or cyclic polydimethylsiloxane, iii) a polydimethylsiloxane comprising alkyl or alkoxy groups, which are pendent and/or at the end of the silicone chain, these groups each comprising from 2 to 24 carbon atoms, wherein: at least one of the non-volatile silicone oils is a first non-volatile silicone oil, selected from the group consisting of the phenyl silicone oils of formula (II) and of formula (VII) with p=0 and at least one of the non-volatile silicone oils is a second non-volatile silicone oil, selected from the group consisting of the phenyl silicone oils of formula (VII) with p≠0 and R3 and R4 are saturated or unsaturated, linear or branched C1-C30 radicals, which are pendent and/or at the end of the silicone chain, these groups each comprising from 2 to 24 carbon atoms and (d) at least one agent that structures the liquid fatty phase, in a content of less than or equal to 20% by weight relative to the total weight of the composition. |
