## Background
CROSS REFERENCE TO RELATED APPLICATION
This application is a Continuation Application of co-pending U.S. application Ser. No. 10/877,539, filed on Jun. 25, 2004, now abandoned which claims priority under 37 U.S.C. § 119(e) to U.S. Provisional Application Ser. No. 60/483,350, filed Jun. 27, 2003.


FIELD OF THE INVENTION
The present invention relates to compositions containing an antimicrobial agent for treating fabric articles, especially articles of clothing, linens and drapery, wherein the compositions provide improved cleaning of soils from and/or care of and/or treatment of fabric articles, especially while providing superior garment care for articles sensitive to water as compared to conventional fabric article treating compositions.
BACKGROUND OF THE INVENTION
For the cleaning of fabric articles consumers currently have the choice of conventional laundry cleaning or dry cleaning.
Conventional laundry cleaning is carried out with relatively large amounts of water, typically in a washing machine at the consumer's home, or in a dedicated place such as a coin laundry. Although washing machines and laundry detergents have become quite sophisticated, the conventional laundry process still exposes the fabric articles to a risk of dye transfer and shrinkage. Significant portions of fabric articles used by consumers are not suitable for cleaning in a conventional laundry process. Even fabric articles that are considered “washing machine safe” frequently come out of the laundry process badly wrinkled and require ironing.
Dry cleaning processes rely on non-aqueous solvents for cleaning. By avoiding water these processes minimize the risk of shrinkage and wrinkling; however, cleaning of soils, particularly water-based and alcohol-based soils, is very limited with these processes. Typically, the dry-cleaner removes such soils by hand prior to the dry-cleaning process. These methods are complex, requiring a wide range of compositions to address the variety of stains encountered, very labor intensive and often result in some localized damage to the treated article.
Accordingly there is an unmet need, in commercial laundry, in dry-cleaning and in the home, for fabric article treating compositions, which simultaneously provide acceptable cleaning of across a variety of soils while remaining safe for a wide range of fabric articles.
SUMMARY OF THE INVENTION
The present invention provides compositions which exhibit improved cleaning of soils from and/or care of and/or treatment of fabric articles. These benefits may be delivered to the fabric article treated by the compositions of the present invention while maintaining excellent fabric care properties.
In one aspect of the present invention, a fabric article treating composition comprises:

    
    
        a) a lipophilic fluid; and
        b) an antimicrobial agent; and
        c) a surfactant component capable of enhancing soil removal benefits of a lipophilic fluid and/or capable of suspending water in a lipophilic fluid; and
        d) optionally, a non-silicone additive capable of further enhancing soil removal by the composition; and
        e) optionally, water; and
        f) optionally, other cleaning adjuncts; and
        g) optionally, processing aids;
        wherein the surfactant component comprises at least one nonionic surfactant and at least one siloxane-based surfactant.
    
    


In another aspect of the present invention, a consumable detergent composition comprises:

    
    
        a) a surfactant component comprising at least one nonionic surfactant and at least one siloxane-based surfactant; and
        b) an antimicrobial agent; and
        c) optionally, a non-silicone additive capable of further enhancing soil removal by the composition; and
        d) optionally, a polar solvent; and
        e) optionally, other cleaning adjuncts; and
        f) optionally, lipophilic fluid; and

wherein the composition is capable of suspending water in a lipophilic fluid.

All percentages, ratios and proportions herein are by weight, unless otherwise specified. All temperatures are in degrees Celsius (° C.) unless otherwise specified. All measurements are in SI units unless otherwise specified. All documents cited are, in relevant part, incorporated herein by reference.


DETAILED DESCRIPTION OF THE INVENTION
Definitions
The term “fabric article” used herein is intended to mean any article that is customarily cleaned in a conventional laundry process or in a dry cleaning process. As such, the term encompasses articles of clothing, linens, drapery, and clothing accessories. The term also encompasses other items made in whole or in part of fabric, such as tote bags, furniture covers, tarpaulins and the like.
The term “fabric article treating composition” used herein is intended to mean any lipophilic fluid-containing composition containing cleaning and/or care additives that comes into direct contact with fabric articles to be cleaned. It should be understood that the term “fabric article treating composition” encompasses uses other than cleaning, such as conditioning and sizing. Furthermore, optional cleaning adjuncts such as additional surfactants other than those surfactants described above, bleaches, and the like may be added to the “fabric article treating composition”. That is, cleaning adjuncts may be optionally combined with the lipophilic fluid. These optional cleaning adjuncts are described in more detail herein below. Such cleaning adjuncts may be present in the fabric article treating compositions of the present invention at a level of from about 0.01% to about 10% by weight of the fabric article treating composition.
The term “soil” means any undesirable substance on a fabric article that is desired to be removed. By the terms “water-based” or “hydrophilic” soils, it is meant that the soil comprised water at the time it first came in contact with the fabric article, or the soil retains a significant portion of water on the fabric article. Examples of water-based soils include, but are not limited to, beverages, many food soils, water soluble dyes, bodily fluids such as sweat, urine or blood, and outdoor soils such as grass stains and mud.
The term “capable of suspending water in a lipophilic fluid” means that a material is able to suspend, solvate and/or emulsify water, in a way that the water remains visibly suspended, solvated or emulsified when left undisturbed for a period of at least five minutes after initial mixing of the components. In some examples of compositions in accordance with the present invention, the compositions may be colloidal in nature and/or appear milky. In other examples of compositions in accordance with the present invention, the compositions may be transparent.
The term “insoluble in a lipophilic fluid” means that when added to a lipophilic fluid, a material physically separates from the lipophilic fluid (i.e. settle-out, flocculate, float) within 5 minutes after addition, whereas a material that is “soluble in a lipophilic fluid” does not physically separate from the lipophilic fluid within 5 minutes after addition.
The term “consumable detergent composition” means any detersive composition, that when combined with a discrete lipophilic fluid, results in a fabric article treating composition according to the present invention.
The term “processing aid” refers to any material that renders the consumable detergent composition more suitable for formulation, stability, and/or dilution with a lipophilic fluid to form a fabric article treating composition in accordance with the present invention.
The term “mixing” as used herein means combining two or more materials (i.e., more specifically a discrete lipophilic fluid and a detergent composition in accordance with the present invention) in such a way that a homogeneous mixture or stable dispersion or suspension is formed. Suitable mixing processes are known in the art. Nonlimiting examples of suitable mixing processes include vortex mixing processes and static mixing processes.
“Solvent compatibility group”, as used herein, means any hydrocarbon, silicone, polyalkylene oxide (ethoxy, propoxy, butoxy, etc. and mixtures) or flurorinated groups. Hydrocarbon groups may be linear, cyclic, branched, saturated or unsaturated straight and branched chain linear aliphatic; saturated and unsaturated cyclic aliphatic, including heterocyclic aliphatic; or mononuclear or polynuclear aromatics, including heterocyclic aromatics. Polyoxyalkylene groups may comprise of one or more or a mixture of alkoxy repeat units. Silicone and fluorinated groups may consist of one or more or a mixture of repeat units.
“Functionalized”, as used herein, means the indicated solvent compatibility groups are chemically bonded to the polyol.
A “functional unit”, as used herein, means one solvent compatibility group used to functionalize the polyol.
COMPOSITIONS OF THE PRESENT INVENTION
The present invention provides compositions which exhibit improved cleaning of soils (i.e., removal and/or reduction of soils) from and/or care of and/or treatment of fabric articles. These benefits may be delivered to the fabric article treated by the compositions of the present invention while maintaining excellent fabric care properties.
Lipophilic Fluid
“Lipophilic fluid” as used herein means any liquid or mixture of liquid that is immiscible with water at up to 20% by weight of water. In general, a suitable lipophilic fluid can be fully liquid at ambient temperature and pressure, can be an easily melted solid, e.g., one that becomes liquid at temperatures in the range from about 0° C. to about 60° C., or can comprise a mixture of liquid and vapor phases at ambient temperatures and pressures, e.g., at 25° C. and 1 atm. pressure.
It is preferred that the lipophilic fluid herein be non-flammable or, have relatively high flash points and/or low VOC characteristics, these terms having conventional meanings as used in the dry cleaning industry, to equal or, preferably, exceed the characteristics of known conventional dry cleaning fluids.
Non-limiting examples of suitable lipophilic fluid materials include siloxanes, other silicones, hydrocarbons, glycol ethers, glycerine derivatives such as glycerine ethers, perfluorinated amines, perfluorinated and hydrofluoroether solvents, low-volatility nonfluorinated organic solvents, diol solvents, other environmentally-friendly solvents and mixtures thereof.
“Siloxane” as used herein means silicone fluids that are non-polar and insoluble in water or lower alcohols. Linear siloxanes (see for example U.S. Pat. Nos. 5,443,747, and 5,977,040) and cyclic siloxanes are useful herein, including the cyclic siloxanes chosen from octamethyl-cyclotetrasiloxane (tetramer), dodecamethyl-cyclohexasiloxane (hexamer), and preferably decamethyl-cyclopentasiloxane (pentamer, commonly referred to as “D5”). A preferred siloxane comprises more than about 50% cyclic siloxane pentamer, more preferably more than about 75% cyclic siloxane pentamer, most preferably at least about 90% of the cyclic siloxane pentamer. Also preferred for use herein are siloxanes that are a mixture of cyclic siloxanes having at least about 90% (preferably at least about 95%) pentamer and less than about 10% (preferably less than about 5%) tetramer and/or hexamer.
The lipophilic fluid can include any fraction of dry-cleaning solvents, especially newer types including fluorinated solvents, or perfluorinated amines. Some perfluorinated amines such as perfluorotributylamines, while unsuitable for use as lipophilic fluid, may be present as one of many possible adjuncts present in the lipophilic fluid-containing composition.
Other suitable lipophilic fluids include, but are not limited to, diol solvent systems e.g., higher diols such as C6 or C8 or higher diols, organosilicone solvents including both cyclic and acyclic types, and the like, and mixtures thereof.

“Ozone Reactivity” as used herein is a measure of a VOC's ability to form ozone in the atmosphere. It is measured as grams of ozone formed per gram of volatile organics. A methodology to determine ozone reactivity is discussed further in W. P. L. Carter, “Development of Ozone Reactivity Scales of Volatile Organic Compounds”, Journal of the Air & Waste Management Association, Vol. 44, Page 881–899, 1994. “Vapor Pressure” as used can be measured by techniques defined in Method 310 of the California Air Resources Board.
Preferably, the lipophilic fluid comprises more than 50% by weight of the lipophilic fluid of cyclopentasiloxanes, (“D5”) and/or linear analogs having approximately similar volatility, and optionally complemented by other silicone solvents.
