Abstract

A system dispensing for vapors of a volatile odor controlling material, comprising a reservoir and a membrane forming at least a portion of the wall of said reservoir and having an external surface in contact with the surrounding atmosphere, and a liquid containing odor controlling agent in said tank in contact with the internal surface of said membrane, characterized in that, together, a) said odor controlling agent is an air treatment agent of the essential oil type in the tank; b) said membrane is a hydrophilic membrane mechanically resistant to water up to 60ºC and having an equilibrium water content of at least 15% by weight calculated on the total weight of the membrane; and c) said liquid is an aqueous dispersion of said air treatment agent defined in a) in an aqueous dispersion medium.
