The present invention relates to a fragrance delivery system which comprises one or more .beta.-ketoester pro-fragrances or pro-accords, said fragrance delivery system useful in a stable, preferably clear, aqueous odor-absorbing composition. The odor-absorbing composition can be further characterized in that they comprise solublized, uncomplexed cyclodextrin, and cyclodextrin compatible antimicrobial actives, cyclodextrin compatible surfactants, cyclodextrin compatible humectants, or mixtures thereof.
