摘要:
The present invention relates to a cosmetic composition comprising:a) at least one polysiloxane bearing a joining group, corresponding to one of the following formulae (IIa) and (IIb): in which: the R radicals represent a C1-C20 hydrocarbon-based group; the Q1, Q2 and Q3 radicals represent either an R radical as defined above; or a joining group capable of forming at least 3 H bonds; it being understood that at least one of the Q1 to Q3 radicals is other than R in formula (IIa); the Q4 divalent radical represents a joining group capable of forming at least 3 H bonds; b) a polyalkene-based supramolecular polymer which can be obtained by reaction of a functionalised polyalkene polymer with a functionalised joining group, said joining group being capable of forming at least 3 H (hydrogen) bonds. The invention also relates to a cosmetic treatment process using said composition.

The present invention relates to a cosmetic process for softening the wrinkles of wrinkled skin comprising a stage consisting in applying, to said wrinkled skin, a cosmetic composition, in particular an anti-wrinkle composition, comprising, in a physiologically acceptable medium suitable for topical application to the skin of the face: from 0.1 to 20% by weight of at least one tensioning agent, with respect to the total weight of the composition, and at least one dispersion in a liquid fatty phase of solid particles of a grafted ethylenic polymer. This composition makes it possible to contribute a persistent tensioning effect to the keratinous substances to which it is applied.

A cosmetic composition includes, in a physiologically acceptable medium, at least one statistical copolymer with a linear main chain of ethylenic nature, in which the copolymer: (i) has a weight-average molecular mass of between 15,000 and 600,000 g/mol, and has: (a) at least 70% by weight of “monomer units” derived from monomers for which the homopolymers are hydrophobic and have a glass transition temperature of greater than 40° C., (b) at least one “monomer unit” derived from an at least partially neutralized ionic hydrophilic monomer, (c) 0 to 25% by weight of “monomer units” derived from additional monomers for which the homopolymers have a glass transition temperature of less than 40° C., chosen from: the acrylates of formula: CH2═CHCOOR12 in which R12 represents a linear or branched C1 to C12 alkyl group with the exception of a tert-butyl group, in which is (are) optionally intercalated one or more identical or different heteroatoms, the alkyl group also possibly being optionally substituted with one or more identical or different substituents chosen from hydroxyl groups and halogen atoms, and the methacrylates of formula: CH2═C(CH3)COOR14 in which R14 represents a linear C4 to C12 alkyl group or a branched C5 to C12 alkyl group, and (ii) has an overall glass transition temperature of greater than or equal to 45° C.

Disclosed herein is a nail varnish composition comprising, in a cosmetically acceptable medium, at least one film-forming polymer, wherein the varnish composition is capable of forming a film having a rate of mass loss of less than 0.5 mg/minute when the film is subjected to abrasion produced with the Taber abrasimeter at 23° C., as well as a method for making up and/or non-therapeutic care of the nails comprising applying to the nails the composition.
摘要:
The present invention relates to a cosmetic composition adapted for a topical application on the skin, especially an anti-wrinkle composition, comprising, in a medium compatible with the skin: at least one tensioning agent, the said tensioning agent being present in a content ranging from 0.01% to 20% relative to the total weight of the composition; and at least one non-elastomeric, water-in soluble film-forming linear block ethylenic polymer, the said polymer being present in a content ranging from 0.01% to 20% relative to the total weight of the composition. This composition makes it possible to give a remanent tensioning effect to the skin to which it is applied.
