<p>The method involves processing the air in the system with an active agent. A mixture made from a high-boiling aldehyde, particularly jasmonal H and a high-boiling phenol, particularly thymol are used as active agent. The aldehyde and phenol are provided in a specific weight ratio. The active mixture is released slowly and evaporated from the carrier material. The active mixture is distributed in a matrix of a cross-linked, hydrophilic group containing polymers, to form a gel-like mass, from which the active agent is released slowly and evaporated.</p> |
