Molecularly imprinted polymer for selectively trapping odorous molecules

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, 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.
