Abstract:
The invention relates to the use of molecularly imprinted polymer(s) or MIPs, of odorous molecule(s), as deodorant agent in particular for selectively trapping molecules that are the cause of human body odour. More particularly by using MIPs which may be obtained via polymerization of “sol-gel” type; it being understood that the polymerization is performed in the presence v) of one or more “templates” of target molecule(s) responsible for human body odour. Another subject of the invention concerns a NI process for preparing MIPs as defined previously, MIPs obtained via this process, and a cosmetic composition comprising at least one MIP as defined previously. Unexpectedly, it appears that the MIPs make it possible to specifically trap precursors of odorous molecules and odorous molecules that may be used in cosmetic formulations, especially those that are the cause of the unpleasant odour of sweat.

The invention relates to the use of molecularly imprinted polymer(s) or MIPs, of odorous molecule(s), as deodorant agent in particular for selectively trapping molecules that are the cause of human body odour. More particularly by using MIPs which may be obtained via polymerization, preferably via radical polymerization, of a mixture of: i) optionally one or more polymerization initiator(s); ii) one or more functional monomer(s); iii) one or more crosslinking agent(s); and iv) one or more porogenic solvent(s); it being understood that the polymerization a) or b) is performed in the presence v) of one or more “templates” of target molecule(s) responsible for human body odour. Another subject of the invention concerns a process for preparing MIPs as defined previously, MIPs obtained via this process, and a cosmetic composition comprising at least one MIP as defined previously.

Abstract:
The invention relates to a dyeing composition comprising a fluorescent disulphide dye and to a method of dyeing keratin materials, with a lightening effect, that employs said composition. It likewise relates to new fluorescent disulphide dyes and to their uses in the lightening of keratin materials. This composition allows a particularly persistent lightening effect to be obtained.
Abstract:
The present invention relates to a process for treating keratin materials, especially human keratin fibers, comprising the application of a composition comprising i) at least one flavin derivative and ii) at least one polymerizable molecule, preferably a photopolymerizable molecule, and at least one step of exposing said materials to artificial or natural light radiation, in particular for caring for and/or repairing the keratin materials.
Abstract:
The invention relates to i) a process for treating keratin fibres, in particular human keratin fibres such as the hair, employing a) at least one monosaccharide with amine group(s), b) at least one polysaccharide with amine group(s) then c) a heat treatment; ii) a composition having an acid pH comprising the ingredients a), b) and c) at least one organic or mineral acid a), b) and c) then heat to treat keratin fibres, in particular human keratin fibres such as the hair, and iv) a multi-compartment kit or device comprising a) and b). The invention makes it possible to improve the cosmetic effect of the keratin fibres intrinsically, in order to prevent or reduce the breakage of natural keratin fibres and/or to repair damaged keratin fibres, while retaining or even improving the manageability, anti-frizz properties and/or persistence of the styling of said fibres, in particular human fibres such as the hair, when a heating step is carried out.
Abstract:
A subject matter of the invention is a molecularly imprinted polymer obtained by polymerization of a mixture comprising a silane, a tetra(C1-C4)alkyl orthosilicate, a porogenic solvent and a C14-C20 fatty acid. Cosmetic composition comprising such a polymer. Cosmetic method for preventing and/or treating dandruff of the scalp using such a polymer.
Abstract:
The invention relates to i) a process for treating keratin fibres, in particular human keratin fibres such as the hair, employing a) at least one oxidized polysaccharide, in particular oxidized inulin, and b) at least one (poly)saccharide with amine group(s); ii) a composition comprising the ingredients a) and b); iii) the use of a) and b) to treat keratin fibres, in particular human keratin fibres such as the hair, and iv) a multi-compartment kit or device comprising a) and b). The invention makes it possible to obtain good hair-conditioning cosmetic properties, with a long-lasting effect.
Abstract:
The invention relates to a cosmetic process for caring for the skin, more particularly facial skin, in particular wrinkled skin, comprising: either the topical application to the skin of an extemporaneous mixture of a cosmetic composition comprising a hyaluronic acid polymer grafted with (meth)acrylate groups and an amine compound; or the sequential application to the skin of a cosmetic composition comprising a hyaluronic acid polymer grafted with (meth)acrylate groups and of an amine compound having one or more primary amine and/or secondary amine groups. The invention also relates to the use of said grafted hyaluronic acid polymer and of said amine compound as a skin tensioning agent.The invention also relates to a cosmetic composition obtained by mixing a cosmetic composition comprising said grafted hyaluronic acid polymer and said amine compound.The invention relates to a kit comprising a first cosmetic composition comprising said grafted hyaluronic acid polymer and a second composition comprising said amine compound, the first and second compositions each been packaged in a distinct packaging assembly.
