The invention relates to a holder for an active ingredient comprising a fixing portion for mechanical fixing under a toilet bowl rim, and a receiving portion joined to the fixing portion for receiving an active ingredient. One problem of such known holders is that they are troublesome to fix to the toilet bowl and to remove again therefrom. This disadvantage is overcome according to the invention by at least parts of the fixing portion being formed from a biodegradable, preferably water-soluble material.
