ABSTRACT:
TECHNICAL FIELD
The present invention relates to aqueous, preferably clear, compositions, articles of manufacture and/or method of use, for reducing malodor impression, comprising low levels of perfumes preferably having perfume ingredients with a Clog P of 3 or smaller; optionally, but preferably, water-soluble cyclodextrin; optionally, but preferably, water-soluble metallic salt; and optionally, but preferably, a solubilizing aid. Preferably, the compositions are designed to reduce malodor on inanimate surfaces, especially, clothes, e.g., those that have been stored for a long period of time, that are contaminated with environmental odors such as food odors, tobacco odors, and that are wetted with perspiration. Preferably the composition is used to restore and/or maintain freshness by reducing malodor without the need for washing or dry cleaning.
BACKGROUND OF THE INVENTION
The present invention relates to aqueous, preferably clear, compositions, articles of manufacture, and/or method for use, as a freshening composition. Preferably, the compositions are sprayed onto fabrics, particularly clothes, to restore their freshness by reducing malodor impression, without washing or dry cleaning. Fabrics treated with some preferred compositions of the present invention also release extra fragrance upon rewetting, such as when the wearer perspires. The freshening compositions of the present invention are designed to extend the wear of fabrics between washing or dry cleaning. Fabrics treated with some preferred freshening compositions of the present invention will stay fresher longer, and receive extra freshening effect via perfume release when it is most needed, that is upon fabric rewetting.
Odor masking is the intentional concealment of one odor by the addition of another. The preference to the masking perfume is varied greatly, depending on the application, e.g., underarm odor masking, fabric odor masking, bathroom odor masking, etc. The art teaches the use of perfume as an odor masking device in combination with alcohol in order to solubilize the perfume. It has now been discovered that perfumes with a Clog P of less than 3 do not need alcohol in order to be solubilized.
SUMMARY OF THE INVENTION
The present invention relates to an aqueous composition for reducing malodor impression, comprising:
(A) from about 0.01% to about 1%, by weight of the composition, of perfume wherein the perfume preferably comprises ingredients having a Clog P of 3 or smaller;
(B) optionally, but preferably, from about 0.1% to about 5%, by weight of the composition of, water-soluble cyclodextrin;
(C) optionally, but preferably, from about 0.1% to about 10%, by weight of the composition, of water-soluble metallic salt;
(D) optionally, but preferably, from about 0% to about 3%, by weight of the composition, of solubilizing aid; and
(E) aqueous carrier; and
wherein said composition is essentially free of any material that would soil or stain fabric and wherein said composition contains less than about 5%, by weight of the composition of low molecular weight monohydric alcohols.
The composition can be incorporated into a spray dispenser to create an article of manufacture that can facilitate treatment of articles and/or surfaces with the composition to reduce malodor at a level that is effective, yet is not discernible when dried on the surface.
DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to an aqueous composition for reducing malodor impression, comprising:
(A) from about 0.01% to about 1%, by weight of the composition, of perfume wherein the perfume preferably comprises ingredients having a Clog P of 3 or smaller;
(B) optionally, but preferably, from about 0.1% to about 5%, by weight of the composition of, water-soluble cyclodextrin;
(C) optionally, but preferably, from about 0.1% to about 10%, by weight of the composition, of water-soluble metallic salt;
(D) optionally, but preferably, from about 0% to about 3%, by weight of the composition, of solubilizing aid; and
(E) aqueous carrier; and
wherein said composition is essentially free of any material that would soil or stain fabric and wherein said composition contains less than about 5%, by weight of the composition of low molecular weight monohydric alcohols.
I. COMPOSITION
(A) PERFUME
The perfume selected for use in the fabric freshening composition of the present invention contains ingredients with odor characteristics which are preferred in order to provide a fresh impression on the surface to which the composition is directed, preferably those which provide a fresh impression for fabrics.
Preferably, at least about 25%, more preferably at least about 50%, most preferably at least about 75%, by weight of the perfume is composed of fragrance material selected from the group consisting of aromatic and aliphatic esters having molecular weights from about 130 to about 250; aliphatic and aromatic alcohols having molecular weights from about 90 to about 240; aliphatic ketones having molecular weights from about 150 to about 260; aromatic ketones having molecular weights from about 150 to about 270; aromatic and aliphatic lactones having molecular weights from about 130 to about 290; aliphatic aldehydes having molecular weights from about 140 to about 200; aromatic aldehydes having molecular weights from about 90 to about 230; aliphatic and aromatic ethers having molecular weights from about 150 to about 270; and condensation products of aldehydes and amines having molecular weights from about 180 to about 320; and essentially free from nitromusks and halogenated fragrance materials.
More preferably, at least about 25%, more preferably at least about 50%, most preferably at least about 75%, by weight of the perfume is composed of fragrance material selected from the group consisting of:
