Abstract
A fragrance-dispensing system comprises a wick and diffuser, wherein the diffuser surface in contact with surrounding air is larger than the wick surface in contact with the air, a container for receiving the wick, and a fragrance preparation in the container, wherein the fragrance is transported by the wick to the diffuser by capillary action. At least sections of the diffuser include a color-changing agent that interacts with at least one substance present in the fragrance such that a color change is produced on and/or in the diffuser section when the substance comes into contact with the color changing agent.
