Title
(EN) MOLECULARLY IMPRINTED POLYMER OF SOL-GEL TYPE FOR SELECTIVELY TRAPPING ODOROUS MOLECULES

Abstract
(EN) 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 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.
(FR) L'invention concerne l'utilisation d'un/de polymère(s) à empreinte moléculaire ou PEM, de molécule(s) odorante(s), comme agent désodorisant, en particulier destiné à piéger sélectivement des molécules qui sont à l'origine de l'odeur corporelle humaine. L'invention concerne plus particulièrement l'utilisation de PEM qui peuvent être obtenus via une polymérisation de type "sol-gel" ; il est entendu que la polymérisation est réalisée en présence v) d'une ou de plusieurs "matrices" de molécule(s) cible(s) responsable(s) de l'odeur corporelle humaine. Un autre objet de l'invention concerne un procédé pour la préparation de PEM tels que définis précédemment, les PEM obtenus par ce procédé et une composition cosmétique comprenant au moins un PEM tel que défini précédemment. De manière inattendue, il s'avère que les PEM qui peuvent être utilisés dans des formulations cosmétiques permettent de piéger plus particulièrement des précurseurs de molécules odorantes et des molécules odorantes, en particulier celles qui sont à l'origine de l'odeur désagréable de la transpiration.
