The invention relates to perfume dispensers for room air improvement, consisting of a packaging system with controllable Luftdurchstroemung, a reversibly ad- and desorbent Traegerstoff high fragrance uptake capacity and a fragrance composition. The operating principle consists in the displacement desorption of the fragrances with water vapor in the gas phase, being used as carriers crystalline aluminosilicates in powder or granular form. By selective choice of the critical molecular diameter of the fragrance components, the use of a chromatographic effect during desorption is possible. |
