Abstract: The present invention relates to a composition comprising a polymeric elastomeric phase and an odoriferous active compound. In particular the present invention relates to a composition comprising a polymeric elastomeric phase and an odoriferous active compound and releasing said odoriferous active compound over a given period of time. The present invention concerns also objects comprising a polymeric elastomeric phase and an odoriferous active compound and releasing said odoriferous active compound over a given period of time.
