Zusammenfassung:	Fragrance releasing crystal beads are provided which gradually release a fragrance under anhydrous conditions and provide a rapid release of fragrance when wetted. She beads comprise a water-soluble particulate carrier, e.g. prilled urea, coated with a finely divided highly absorptive inorganic matrix containing the fragrance. The beads optionally include emollients and bacteriostats and the like and can be used for pleasingly perfumed sachets or as bath beads or as agents for the control of malodors in pet litter. The particulate beads may be conspicuously colored such that their color substantially disappears as they are dissolved, giving a visual indication of the need for replenishment.
