Description: The use of a peroxygen bleach as a fabric/textile softening agent Technical Field The present invention relates to the use of a peroxygen bleach as a fabric/textile softening agent in a composition to treat fabrics and/or textiles. Background of the Invention Carpets produced from synthetic or natural fibers and mixtures thereof are commonly used in residential and commercial applications as a floor covering. Various types of fibers can be used in making carpets such as polyamide fibers, polyester fibers as well as wool, cotton or even silk in the case of rugs. However, carpets irrespective of whether they are made from natural or synthetic fibers are all prone to soiling and staining when contacted with many household items. Foods, grease, oils, beverages in particular such as coffee, tea and soft drinks especially those containing acidic dyes can cause unsightly, often dark stains on carpets. Also fibers may become soiled as a result of dirt particles, clay, dust, i.e., particulate soils in general, coming into contact with and adhering to the fibers of the carpet. These latter soils often appear in the form of a diffuse layer of soils rather than in the form of spots and tend to accumulate particularly in the so called "high traffic areas" such as near doors as a result of intensive use of the carpets in such areas. Another major concern in the care of carpeting, besides the overall cleaning performance desired for a given treating process, is sanitizing. Indeed it is important to reduce or even prevent microbial contamination on carpet surfaces. This is especially important in houses with pets, hotels or in hospitals and other health care facilities, where the presence of micro-organisms like bacteria should be kept to a minimum. Compositions for the treatment of carpets are already known in the art. For example carpet cleaning compositions based on surfactants and polyvinylpyrrolidone as disclosed in EP-A-822 249. However, such compositions are not fully satisfactory from a consumer viewpoint. In particular, it is well known from consumer research that consumers are often looking for a composition to treat carpets whereby the carpet surface feels softer. It is therefore an object of the present invention to provide a composition to treat carpets that imparts softness characteristics to carpets treated therewith. It has now been found that the above objective can be met by the use of a peroxygen bleach as a fabric/textile softening ingredient in a composition to treat carpets. An advantage of the compositions according to the present invention is that they provide excellent overall cleaning performance. More advantageously, the compositions according to the present invention provide excellent cleaning performance, when both used to clean the whole carpet or localized carpet stains. Advantageously, excellent cleaning performance is obtained on different types of stains and soils, including bleachable stains, especially in the so called "high traffic areas". A further advantage of the present invention is that the compositions as described herein are applicable to all carpet types, especially delicate natural fibers, and are also safe to all carpet dye types, particularly sensitive natural dyes used therein. Another advantage of the present invention is that said softness characteristics are also provided to other textiles besides carpets, as for example, upholstery or car seat covering, and to fabrics (e. g., clothes, curtains, drapes, bed linens, bath linens, table cloths, sleeping bags, tents and the like). Yet another advantage of the composition as described herein is that they may be applied directly on the carpet without causing damage to the carpet. Summary of the Invention The present invention encompasses the use of a peroxygen bleach as a fabric/textile softening ingredient in a composition to treat fabrics and/or textiles whereby softness characteristics are provided to said fabrics and/or textiles. Detailed Description of the Invention The composition The compositions according to the present invention may be formulated either as solids or liquids. In the case where the compositions are formulated as solids for example as granular compositions or powder compositions, they may be applied directly on the fabrics and/or textiles, preferably carpets, to be treated or they may be diluted before use with an appropriate solvent, typically water. Liquid compositions are preferred herein for convenience of use. In the case where the compositions are formulated as liquids including gel and paste form, the compositions are preferably but not necessarily formulated as aqueous compositions. Preferred aqueous compositions preferably comprise water in an amount of from 60% to 98%, more preferably of from 80% to 95% and most preferably 85% to 90% by weight of the total composition. The pH of the liquid compositions according to the present invention may typically be from 1 to 14. In a preferred embodiment, the recommended pH range is from 1 to 10, preferably between 2 and 8, more preferably between 3 and 7, even more preferably between 4.5 and 7 and most preferably between 3.5 and 6.5. Indeed, it has been surprisingly found that cleaning performance is further improved at these preferred pH ranges. Also these preferred pH ranges contribute to the stability of hydrogen peroxide, when present. Accordingly, the compositions herein may further comprise an acid or base or a mixture thereof to adjust the pH as appropriate. Preferred acids herein are organic or inorganic acids or mixtures thereof. Preferred organic acids are acetic acid or citric acid or a mixture thereof. Preferred inorganic acids are sulfuric acid or phosphoric acid or a mixture thereof. A particularly preferred acid to be used herein is an inorganic acid and most preferred is sulfuric acid. Typical levels of such acids, when present, are of from 0.01 % to 1.0% by weight, preferably from 0.05% to 0.8% and more preferably from 0.1% to 0.5% by weight of the total composition. The bases to be used herein can be organic or inorganic bases. Suitable bases for use herein are the caustic alkalis, such as sodium hydroxide, potassium hydroxide and/or lithium hydroxide, and/or the alkali metal oxides such, as sodium and/or potassium oxide or mixtures thereof. A preferred base is a caustic alkali, more preferably sodium hydroxide and/or potassium hydroxide. Other suitable bases include ammonia, ammonium carbonate and hydrogen carbonate. Typical levels of such bases, when present, are of from 0.01 % to 1.0% by weight, preferably from 0.05% to 0.8% and more preferably from 0.1 % to 0.5% by weight of the total composition. Fabric/textile softening ingredient Peroxygen bleach is used as fabric/textile softening agent in compositions to treat fabrics and/or textiles, preferably carpets, whereby softness characteristics are provided to said fabrics and/or textiles. Suitable peroxygen bleaches to be used herein are selected from the group consisting of : hydrogen peroxide; water soluble sources of hydrogen peroxide; organic or inorganic peracids; hydroperoxides; diacyl peroxides; and mixtures thereof. As used herein a hydrogen peroxide source refers to any compound that produces perhydroxyl ions when said compound is in contact with water. Suitable water-soluble sources of hydrogen peroxide for use herein are selected from the group consisting of percarbonates, perborates and persilicates and mixtures thereof. Suitable diacyl peroxides for use herein are selected from the group consisting of aliphatic, aromatic and aliphatic-aromatic diacyl peroxides, and mixtures thereof. Suitable aliphatic diacyl peroxides for use herein are dilauroyl peroxide, didecanoyl peroxide, dimyristoyl peroxide, or mixtures thereof. A suitable aromatic diacyl peroxide for use herein is for example benzoyl peroxide. A suitable aliphatic-aromatic diacyl peroxide for use herein is for example lauroyl benzoyl peroxide. Such diacyl peroxides have the advantage to be particularly safe to fabrics and color while delivering excellent bleaching performance when used in any laundry application. Suitable organic or inorganic peracids for use herein are selected from the group consisting of : persulphates such as monopersulfate; peroxyacids such as diperoxydodecandioic acid (DPDA); magnesium perphthalic acid; perlauric acid; perbenzoic and alkylperbenzoic acids; and mixtures thereof. Suitable hydroperoxides for use herein are selected from the group consisting of tert-butyl hydroperoxide, cumyl hydroperoxide, 2,4,4-trimethylpentyl-2- hydroperoxide, di-isopropylbenzene-monohydroperoxide, tert-amyl hydroperoxide and 2,5-dimethyl-hexane-2,5-dihydroperoxide and mixtures thereof. Such hydroperoxides have the advantage to be particularly safe to fabrics and color while delivering excellent bleaching performance when used in any laundry application. Preferred peroxygen bleaches herein are selected from the group consisting of : hydrogen peroxide; water soluble sources of hydrogen peroxide; organic or inorganic peracids; hydroperoxides; and diacyl peroxides; and mixtures thereof. More preferred peroxygen bleaches herein are selected from the group consisting of hydrogen peroxide, water soluble sources of hydrogen peroxide and diacyl peroxides and mixtures thereof. Even more preferred peroxygen bleaches herein are selected from the group consisting of hydrogen peroxide, water soluble sources of hydrogen peroxide, aliphatic diacyl peroxides, aromatic diacyl peroxides and aliphatic-aromatic diacyl peroxides and mixtures thereof. Most preferred peroxygen bleaches herein are hydrogen peroxide, water soluble sources of hydrogen peroxide or mixtures thereof. Typically, the liquid compositions herein comprise from 0.01 % to 20%, preferably from 0.5 % to 10%, and more preferably from 1 % to 7% by weight of the total composition of a peroxygen bleach. By "softness characteristics" it is meant herein the softening performance as defined by the softening performance test method as outlined below. The softness characteristics provided by the use of the composition as described herein are perceived by the consumers in a variety of different ways, e.g., soft touch, soft feel, soft appearance, soft texture, smoothness, fluffiness, restored fluffiness, reduced pungency, reduced roughness, reduced coarseness, reduced rudeness, a pile rinsing effect and/or a pile-up effect The softening performance of a composition on fabrics and/or textiles may be evaluated by the following softening performance test method. A composition comprising the fabric/textile softening ingredient according to the present invention is first applied in a liquid form, preferably sprayed, onto a 25 cm * 25 cm piece of carpet, left to act thereon from 1 minute to 1 hour, preferably 30 minutes, after which the carpet is vacuum cleaned with a standard Hoover® vacuum cleaner for 5 seconds to 15 seconds, preferably 10 seconds. The above described treatment is repeated for five times and the pieces of carpets are then evaluated by panelists grading the softness characteristics in comparison to the softness characteristics of a similar piece of carpet treated the way as described above but with a composition not comprising the fabric/textile softening ingredient. The present invention is based on the finding that when a composition comprising a fabric/textile softening ingredient as described is used to treat fabrics and/or textiles, softness characteristics are delivered to the fabrics and/or textiles treated with said composition. Softness characteristics can be observed after the treatment of fabrics and/or textiles having natural fibers, e.g., wool, silk and/or cotton, as well as synthetic fibers, e.g., polyamide or polyester, or fabrics and/or textiles having mixed natural and/or synthetic fibers. By "natural fibers" it is meant fibers consisting to the major part of keratin polypeptides, as for example in wool and in silk, or cellulose molecules, as for example in cotton and jute, or other natural fibers having a natural origin, or mixtures thereof. By "fabrics" it is meant clothes, curtains, drapes, bed linens, bath linens, table cloths, sleeping bags, tents and the like. By "textiles" it is meant carpets, rugs, upholstery, car seat coverings and the like. Although not wishing to be bound by theory, it has been observed that said softness characteristics provided to fabrics and/or textiles treated with a composition described herein may be due to one or more of three speculated effects caused by the fabric/textile softening ingredient. The first effect is fiber plasticization caused by the fabric/textile softening ingredient. By "fiber plasticization" it is meant that due to its minor polarity a peroxygen bleach can easily penetrate between the macromolecules that form the fabric/textile fibers, temporarily overcoming the intra-molecular attractions that tend to hold said macromolecules together, thereby increasing the mobility of the polymeric chains of said macromolecules. The first effect can be observed in fabrics and/or textiles having natural fibers, fabrics and/or textiles having synthetic fibers as well as fabrics and/or textiles having mixed natural and synthetic fibers. The second effect is fiber swelling. By "fiber swelling" it is meant that due to the release of molecules in their gas state, preferably oxygen gas, released by a peroxygen bleach, within fabric/textile fibers, the volume around the macromolecule is increased. Thereby increasing the macromolecule's mobility, i.e., providing twisting/translation freedom. The second effect is predominant in fabrics and/or textiles having synthetic fibers and fabrics and/or textiles having mixed natural and synthetic fibers. The third effect is temporary fiber denaturation. By "temporary fiber denaturation" it is meant that inter/intra-molecular bond and/or attractions connecting fabric/textile fibers, e.g., disulfide bridges connecting cysteine moieties of keratin proteins making up wool fabrics and/or textiles, are oxidised by a peroxygen bleach, preferably due to its oxidising properties, thereby, temporarily stretching/breaking the bonds and/or attractions and resulting in the temporary relaxation of said inter/intra-molecular bonds and/or attractions. Said temporary relaxation leads to a reversible change in the structure of the fibers. The change enables the fibers to move more freely with respect to each other. The third effect is predominant in fabrics and/or textiles having natural fibers and fabrics and/or textiles having mixed natural and synthetic fibers. Peroxygen bleach is used as a fabric/textile softening ingredient in a composition to treat fabrics and/or textiles. Preferably peroxygen bleach is used as a fabric/textile softening ingredient in a composition to treat textiles as carpets, rugs, upholstery, car seat coverings and the like. Even more preferably peroxygen bleach is used as a fabric/textile softening ingredient in a composition to treat carpets, rugs and the like. Most preferably peroxygen bleach is used as a fabric/textile softening ingredient in a composition to treat carpets. The presence of a peroxygen bleach, preferably hydrogen peroxide, also contributes to the excellent cleaning (especially on bleachable stains) and sanitizing benefits of the compositions of the present invention. Indeed, the compositions comprising a peroxygen bleach provide excellent cleaning performance on diffuse soils (e.g., particulate and/or greasy/oily stains) and on other types of stains or soils, i.e., on spot stains like bleachable stains (e.g., coffee, beverage, food) and/or enzymatic stains like blood. Said excellent cleaning performance is provided on various types of fabrics and/or textiles. By "particulate stains" it is meant herein any soils or stains of particulate nature that can be found on any fabric and/or textile, e.g. clay, dirt, dust, mud, concrete and the like. By "greasy/oily stains" it is meant herein any soils or stains of greasy/oily nature that can be found on any fabric and/or textile, e.g., make-up, lipstick, dirty motor oil and mineral oil, greasy food like mayonnaise and spaghetti sauce. By "bleachable stains" it is meant herein any soils or stains containing ingredients sensitive to bleach that can be found on any fabric and/or textile, e.g., coffee or tea. By "enzymatic stains" it is meant herein any soils or stains of enzymatic nature that can be found on any fabric and/or textile, e.g., grass. The cleaning performance of a given composition on soiled fabrics and/or textiles, e.g., carpets, may be evaluated by the following test method. A composition comprising the fabric/textile softening ingredient according to the present invention is first applied in a liquid form, preferably sprayed, onto the stained portion of a carpet, left to act thereon from 1 to 60 minutes, preferably 30 minutes, after which the carpet is vacuum cleaned. Typical soils used in this test may be grass, dirty motor oil, tea, coffee, dust and/or mayonnaise. The cleaning performance may be evaluated by visual grading. Optional ingredients The compositions herein may further comprise conventional fabric/textile cleaning ingredients. Preferably the compositions herein may further comprise a number of additional compounds such as anti-resoiling agents, surfactants, stabilising agents, chelating agents, builder systems, radical scavengers, perfumes, dyes, suds suppressing agents, enzymes, photobleaching agents, bleach activators and other minors. Anti-resoiling agent As an optional but highly preferred ingredient the compositions according to the present invention may comprise an anti-resoiling agent. Any anti-resoiling agent having the desired anti-resoiling properties may be used. By "anti-resoiling properties" it is meant herein that the fabrics and/or textiles, preferably carpets, having been cleaned with a composition according to the present invention, is more effectively cleaned in a subsequent cleaning operation (e.g., mechanical carpet cleaning, as vacuum cleaning, brushing and the like; or carpet cleaning by chemical means). Particularly, it is meant that less effort and/or less product needs to be applied to the fabrics and/or textiles to achieve the same or even a better cleaning versus when the fabrics and/or textiles are cleaned with a composition not containing an anti-resoiling agent. Suitable anti-resoiling agents include anti-resoiling polymers. Suitable anti-resoiling polymers include polyamine N-oxide polymers.

Treatment of a carpet Typically, a carpet is treated by applying the liquid or solid composition, preferably the liquid composition, as described. The compositions according to the present invention may be applied to the carpet to be treated either in neat or diluted form, this applies to compositions being either liquid compositions or solid composition. By "diluted form", it is meant herein that the compositions for treating fabrics and/or textiles, preferably carpets, as described herein before may be diluted by the user, preferably with water. Compositions herein can be diluted up to 150 times, preferably up to 50 times and more preferably up to 25 times. By "in its neat form", it is to be understood that the compositions for treating fabrics and/or textiles, preferably carpets, are applied directly onto the carpets to be treated without undergoing any dilution, i.e., the compositions herein are applied onto the carpets as described herein. Preferably the treatment of a carpet comprises the steps of applying said composition to the surface of the carpet in a liquid form, preferably in a liquid and neat form, and leaving said composition to dry onto the carpet. More preferably said treatment comprises the steps of applying said composition to the surface of the carpet in a liquid form, preferably in a liquid and neat form, leaving said composition to dry onto the carpet and finally removing said composition from said carpet. By "in liquid form" it is meant that the liquid compositions for treating fabrics and/or textiles, preferably carpets, as described herein can be used per se in neat form or in diluted, and the solid compositions as described herein, for example powders, are dissolved in an appropriate solvent, typically water, before use, i.e., before being applied to said carpet. Preferably the composition is applied onto the carpet in the form of a spray of droplets having a particle size distribution with a mean diameter D(v,0.9) of less than 1500 microns, preferably less than 1000 microns, more preferably of less than 750 microns, even more preferably less than 500 microns, and most preferably from 350 microns to 10 microns. By "mean diameter D(v,0.9) of less than 1500 microns" for a droplet size distribution it is meant that 90% of the spray of droplets dispensed (expressed in volume unit) has a droplet diameter of less than 1500 microns. For instance, a D(v,0.9) of less than 1500 microns indicates that 90% of the total sprayed volume is dispensed with droplets whose diameter is less than 1500 microns. The particle size distribution of a spray of droplets can be determined by following the procedure detailed herebelow: A suitable test equipment is the Malvern Mastersizer S LongBed® with 1000 mm lens and a maximum particle size range of 3475 microns. The Malvern Mastersizer S LongBed® provides 21 cm opening (between lenses) to accommodate spray flow. In all readings at the Malvern®, the lens surface must remain free of spray contamination. In the present setup procedure, the distance from nozzle to laser was fixed at 8 cm, this to minimize lens contamination. At 8 cm distance, the spray was directed to the laser beam to place the laser center to the spray cone. At least three readings have to be made for each composition sprayed to determine the particle size distribution of the spray of droplets. The sprayer used in the test according to the present invention was an electrically operated sprayer. With the battery driven system a "Full charge" test was held consistent by holding the spray head to 3.9 voltage direct current (vdc) from an external power supply, this to insure a consistent spray force. A reference sprayer used herein is a hand trigger operated sprayer. Hand trigger systems have to be tested against repeatability with three different persons. These persons chosen for their varied ability to actuate the trigger against force: Small female, female with strong finger strength, and medium male. Any container adapted to deliver a spray of droplets as defined herein is suitable for use herein. Several modifications can be made to the conventional, single aperture, spray head to ensure that a spray of such droplets as required herein is formed. Suitable containers to be used herein (also called "spray dispensers") share the common feature of having at least one aperture or a plurality of apertures also called "dispensing openings" through which the composition is dispensed so as to produce the spray of droplets as defined herein. These spray dispensers may be manually or electrically operated. Typical manually operated spray dispensers include pump operated ones or trigger operated ones. Indeed, in such a container with a spray dispenser head the composition contained in the container is directed through the spray dispenser head via energy communicated to a pumping mechanism by the user as said user activates said pumping mechanism or to an electrically driven pump. Preferred herein is to use a container wherein the means for delivering the composition comprises an electrically driven pump and a spray arm being either extended or extendible and having at least one dispensing opening so that in operation, the composition is pumped by electrically driven pump from the container, through the spray arm to the dispensing opening from which it is dispensed. It is preferred that the spray arm communicates with the container by means of a flexible connector. The spray arm may have one nozzle or multiple nozzles located along its length. The spray arm makes it easier to control where the composition is sprayed. The electrically driven pump may be, for example, a gear pump, an impeller pump, a piston pump, a screw pump, a peristaltic pump, a diaphragm pump, or any other miniature pump. In a highly preferred embodiment of the electrically driven pump for use herein the pump is a gear pump with a typical speed between 6000 rpm and 12000 rpm. The electrically driven pump is driven by a means such as an electric motor which typically produces a torque between 1 and 20 mN.m. The electric motor must in turn be provided with a power source. The power source may be either mains electricity (optionally via transformer), or it may be a throw-away battery or rechargeable battery. The spray arm may be rigidly extended. However such a spray arm can be difficult to store, and the spray arm is preferably extensible either by means of telescopic or foldable configuration. The amount of the compositions for treating fabrics and/or textiles, preferably carpets, according to the present invention applied will depend on the severity of the stain or soil. In the case of stubborn stains more than one application may be required to ensure complete removal of the stain. The area to be treated by applying the compositions according to the present invention may be of any size. Indeed, a complete section or more preferably the whole carpet may be treated with the composition for the treating of carpets according to the present invention. Preferably, in the treatment of a carpet according to the present invention the step of applying a composition onto the carpets as described herein before, does not need to be followed by a step where manual action is required other than a final optional removing step. Indeed the compositions herein allow excellent cleaning performance without requiring any manual action like rubbing and/or brushing. An advantage of the present invention is that the cleaning action of the present compositions commences as soon as said compositions are applied onto said carpet. Typically, in a preferred embodiment of the present invention the composition is left to dry on the carpet for less than 2 hour, preferably less than 1 hour, more preferably less than 40 minutes, even more preferably from 1 to 30 minutes and most preferably from 1 to 20 minutes. By "dry" it is meant herein the stage where at least 40%, preferably at least 60% of the initial amount of composition dispensed onto the carpet is lost due to evaporation. Indeed, in a preferred embodiment of the present invention, said liquid composition is left to dry, preferably until said composition which combined with dirt has been changed into dry residues. More preferably, said composition is then removed from the carpet. Even more preferably said composition is removed mechanically, and most preferably by vacuum cleaning. This may be carried out with the help of any commercially available vacuum cleaners like for instance a standard Hoover® 1300W vacuuming machine. According to the present invention the compositions herein may be used for the removal of stains and soils from fabrics and/or textiles as well as of odors.
