Claims
- 1. A method of treating an inanimate object or inanimate surface which has malodor impression to reduce said malodor impression, said method comprising the step of contacting said inanimate object or inanimate surface with an effective amount of a composition for reducing malodor impression comprising:
(a) from about 0.01% to about 1%, by weight of said composition, of perfume; (b) cyclodextrin; (c) aerosol propellant; (d) optionally, solubilizing aid; and (e) aqueous carrier; wherein said composition is essentially free of any material that would soil or stain fabric; wherein said composition is contained in an aerosol dispenser; and wherein said method provides less than about 5 milligrams of said cyclodextrin per milligram of said inanimate object or said inanimate surface.
- 2. The method of claim 1 wherein said method provides less than about 2 milligrams of said cyclodextrin per milligram of said inanimate object or said inanimate surface.
- 3. The method of claim 1 wherein said composition comprises from about 0.1% to about 5%, by weight of said composition, of cyclodextrin.
- 4. The method of claim 3 wherein said composition comprises from about 0.2% to about 4%, by weight of said composition, of cyclodextrin.
- 5. The method of claim 1 wherein said cyclodextrin is water soluble, uncomplexed cyclodextrin.
- 6. The method of claim 1 wherein said cyclodextrin is selected from the group consisting of alpha-cyclodextrin, beta-cyclodextrin, gamma-cyclodextrin, derivatives thereof, and mixtures thereof.
- 7. The method of claim 6 wherein said cyclodextrin is beta-cyclodextrin.
- 8. The method of claim 6 wherein said cyclodextrin is methylated beta-cyclodextrin.
- 9. The method of claim 6 wherein said cyclodextrin is hydroxyalkyl beta-cyclodextrin.
- 10. The method of claim 9 wherein said hydroxyalkyl beta-cyclodextrin is hydroxypropyl beta-cyclodextrin.
- 11. The method of claim 4 wherein said aerosol propellant is selected from the group consisting of compressed air, nitrogen, inert gas, carbon dioxide, and mixtures thereof.
- 12. The method of claim 11 wherein said aerosol propellant is compressed air.
- 13. The method of claim 11 wherein said aerosol propellant is carbon dioxide.
- 14. The method of claim 1 wherein said composition further comprises said solubilizing aid.
- 15. The method of claim 14 wherein said solubilizing aid is a surfactant selected from the group consisting of nonionic surfactants, cationic surfactants, amphoteric surfactants, zwitterionic surfactants, and mixtures thereof.
- 16. The method of claim 15 wherein said solubilizing aid is a nonionic surfactant.
- 17. The method of claim 16 wherein said nonionic surfactant is selected from the group consisting of polyethylene glycol-propylene glycol block copolymers, ethoxylated branched aliphatic diols, ethoxylated alkyl phenols, ethoxylated aliphatic alcohols, ethoxylated aliphatic carboxylic acids, polyethylene glycol diesters of fatty acids, fatty acid esters of ethoxylated sorbitans, and mixtures thereof.
- 18. The method of claim 17 wherein said nonionic surfactant is an ethoxylated aliphatic alcohol.
- 19. The method of claim 14 wherein said solubilizing aid is present at a level of from about 0.5% to about 3%, by weight of said composition.
- 20. The method of claim 19 wherein said solubilizing aid is present at a level of from about 0.05% to about 1%, by weight of said composition.
- 21. The method of claim 20 wherein said solubilizing aid is present at a level of from about 0.1% to about 0.3%.
- 22. The method of claim 1 wherein said aqueous carrier comprises water.
- 23. The method of claim 22 wherein said aqueous carrier further comprises low molecular weight monohydric alcohol.
- 24. The method of claim 23 wherein said low molecular weight monohydric alcohol is selected from the group consisting of ethanol, methanol, isopropanol, and polyols.
- 25. The method of claim 23 wherein said low molecular weight monohydric alcohol is present at a level of less than about 5%, by weight of said composition.
- 26. The method of claim 25 wherein said low molecular weight monohydric alcohol is present at a level of less than about 3%, by weight of the composition.
- 27. The method of claim 1 wherein said composition further comprises a water-soluble preservative.
- 28. The method of claim 27 wherein said water-soluble preservative is selected from the group consisting of organic sulfur compounds, halogenated compounds, cyclic organic nitrogen compounds, low molecular weight aldehydes, quaternary compounds, dehydroacetic acid, phenyl and phenoxy compounds, and mixtures thereof.
- 29. The method of claim 28 wherein said water-soluble preservative is present at a level of from about 0.0001% to about 0.5%, by weight of said composition.
- 30. The method of claim 29 wherein said water-soluble preservative is present at a level of from about 0.0002% to about 0.2%, by weight of said composition.
- 31. The method of claim 1 wherein said composition further comprises from about 0.1% to about 10%, by weight of said composition, of metallic salt.
- 32. The method of claim 1 wherein said inanimate object or inanimate surface is contacted with said composition by spraying said composition onto said surface.
- 33. The method of claim 32 wherein said inanimate object or inanimate surface is fabric.
