Title
(EN) MOLECULARLY IMPRINTED POLYMER FOR SELECTIVELY TRAPPING ODOROUS MOLECULES
(FR) POLYMÈRE À EMPREINTE MOLÉCULAIRE POUR PIÉGER SÉLECTIVEMENT DES MOLÉCULES ODORANTES
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, 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. 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 de polymère(s) à empreinte moléculaire ou MIP, de molécule(s) odorante(s), en tant qu'agent déodorant en particulier pour piéger sélectivement des molécules qui sont à l'origine d'odeurs corporelles humaines. Plus particulièrement, les MIP peuvent être obtenus par polymérisation, de préférence par polymérisation radicalaire, d'un mélange comprenant : i) éventuellement un ou plusieurs initiateurs de polymérisation ; ii) un ou plusieurs monomères fonctionnels ; iii) un ou plusieurs agents de réticulation ; et iv) un ou plusieurs solvants porogènes ; étant entendu que la polymérisation a) ou b) est effectuée en présence v) d'un ou plusieurs "modèles" de molécule(s) cible(s) responsables d'odeurs corporelles humaines. L'invention concerne également un procédé de préparation de MIP tels que définis précédemment, des MIP obtenus selon ce procédé, et une composition cosmétique comprenant au moins un MIP tel que défini précédemment. De manière inattendue, il apparaît que les MIP permettent en particulier de piéger des précurseurs de molécules odorantes et des molécules odorantes qui peuvent être utilisés dans des formulations cosmétiques, notamment celles qui sont à l'origine de l'odeur désagréable de la sueur.
