Zusammenfassung:The present invention relates to stable, preferably clear, aqueous odor-absorbing compositions, articles of manufacture, and/or method of use, comprising solubilized, uncomplexed cyclodextrin, and perfume in cyclodextrin compatible form. As used herein, "cyclodextrin compatible" means that the cyclodextrin and the perfume, do not substantially interact so as to eliminate the odor controlling ability of the cyclodextrin or the desired effect of the perfume. The odor-absorbing composition is designed to control odors caused by a broad spectrum of organic odoriferous materials, which may, or may not, contain reactive functional groups, and to preferably remain shelf stable for a substantial period of time. Preferably, the aqueous odor-absorbing compositions are for use on inanimate surfaces, especially fabrics, and more specifically, clothes, in order to restore and/or maintain freshness by reducing malodor without the need for washing or dry cleaning. The present invention relates to a stable, aqueous odor-absorbing composition, preferably for use on inanimate surfaces. The composition comprises from about 0.1% to about 0.5%, by weight of the composition, of an emulsion or dispersion comprising long lasting hydrophobic perfume to improve acceptance. Optionally, the composition can contain low molecular weight polyols; metallic salts to help control odor; water soluble anionic polymer to help control odor; a humectant, etc. The composition is preferably essentially free of any material that would soil or stain fabric. The composition is preferably applied as small particle size droplets, especially from spray containers.
