Description: STABILIZED BLEACH COMPOSITIONS FIELD OF THE INVENTION The present invention relates to stabilized bleaching and detergent compositions which compπse a catalytically effective amount of a transition-metal bleach catalyst which is a complex of a transition-metal and a cross-bridged macropolycychc hgand and an anti-oxidant or reducing agent which serves to stabilize said catalyst. The present invention further relates to a method for bleaching/cleaning fabπc with a catalytically effective amount of said stabilized transition-metal bleach catalyst wherein the method is performed substantially free of any organic or inorganic peroxygen compound or precursors to any organic or inorganic peroxygen compound BACKGROUND OF THE INVENTION Bleaching of fabπc is essentially exposing soiled or stained fabnc to a chemical reaction the purpose of which is to eliminate the soil or stam. At one point in time, bleaching involved exposure of fabπc to a solution of hypochlonte. Therefore, fabπc which was colored or dyed via sensitive pigments were excluded from treatment with bleach. To the benefit of the consumer, formulators developed vaπous forms of bleach inter alia peroxygen bleaching systems which typically compπse a source of hydrogen peroxide and a bleach activator. This combination of source of hydrogen peroxide and activator plays a dominating role in effective, safe bleaching compositions. An effective example of this peroxygen bleaching system employs perborate (peroxygen source) and nonanoyloxybenzene sulfonate (activator). In order to boost the performance of bleaching agents and to develop bleaching systems which are safe to any type of dyed or colored fabric inter aha silk, polyester blends, cotton, nylon, formulators have continued to develop peroxygen bleaching systems, as well as new methods of forming activated oxygen. However, there still remains a need in the art for a stable bleaching system which will effectively bleach fabπc without the need for reactive chemicals such as peroxides, sources of peroxide, and/or mixtures thereof. Said stable bleaching system will comprise a transition-metal catalyst which does not loose its effectiveness due to the instability of the catalyst to oxidation and/or reduction post formulation. SUMMARY OF THE INVENTION The present invention meets the aforementioned needs in that it has been surprisingly discovered that bleaching systems compπsing a transition-metal catalyst which are capable of bleaching soils and stains in the absence of a source of hydrogen peroxide or other peroxygen bleaching agent can be successfully stabilized against the unwanted degradation of the transition- metal catalyst. In other words, it has been surprisingly discovered that the addition of an effective amount of an anti-oxidant and/or free radical scavenger or an reducing agent can stabilize a nil hydrogen peroxide bleaching system. A first aspect of the present invention relates to stabilized bleaching compositions comprising: A) a catalytically effective amount of a transition-metal bleach catalyst which is a complex of a transition-metal and a cross-bridged macropolycychc gand; B) an effective amount of a stabilizing agent, said agent selected from l) one or more anti-oxidants; n) one or more reducing agents; in) and mixtures thereof; and C) the balance carriers and other adjunct ingredients; provided said composition is substantially free of any organic or inorganic peroxygen compounds. The present invention further relates to a method for cleaning and/or bleaching soils and stains on fabπcs, said method compπsing the step of contacting the fabπc in need of cleaning and/or bleaching with an aqueous solution containing a composition which is substantially free of a peroxygen source and which compnses. a) a catalytically effective amount of a transition-metal bleach catalyst which is a complex of a transition-metal and a cross-bridged macropolycychc hgand; b) an effective amount of a stabilizing agent, said agent selected from l) one or more anti-oxidants; u) one or more reducing agents; in) and mixtures thereof; and c) the balance earners and other adjunct ingredients; provided the concentration of said transition metal bleach catalyst in the aqueous solution is at least about 0.01 ppb and said composition is substantially free of any organic or inorganic peroxygen compounds. The compositions and methods of the present invention are suitable for cleaning/bleachmg any surface in need of stam removal. For example, hard surface cleaners and automatic dishwashing compositions can employ the bleach catalysts of the present invention m applications which are substantially free of any organic or inorganic peroxygen compounds. These and other objects, features, and advantages will become apparent to those of ordinary skill in the art from a reading of the following detailed description and the appended claims. All percentages, ratios and proportions herein are by weight, unless otherwise specified. All temperatures are in degrees Celsius (° C) unless otherwise specified. All documents cited are in relevant part, incorporated herein by reference. DETAILED DESCRIPTION OF THE INNENTION The present invention relates to the surprising discovery that transition-metal catalysts which are capable of bleaching of soils and stains in the absence of an added peroxygen bleach can be suitably stabilized by the addition of one or more stabilizing agents. The stabilizing agents suitable for use in the present invention are present at varying level depending upon the formulation inter aha liquid, solid, gel, and the concentration of the transition-metal present. Absence of Peroxygen Sources The compositions of the present invention, as well as the methods for cleaning and/or bleaching of fabπc which utilize the compositions of the present invention are substantially free of any peroxygen source such as hydrogen peroxide, peroxyacid etc. The compositions of the present invention need only have an effective amount of the herein below descnbed catalyst present for effective bleaching. For the purposes of the present invention the term "substantially free" is defined as "the formulator does not include in the composition any peroxygen compound or source of peroxygen at a level required for either effective bleaching without a transition metal catalyst, or which would provide an increase in effectiveness of bleaching in the presence of a transition metal catalyst as defined herein." Therefore, as will be further descnbed herein below, effective bleaching of stains can be accomplished by simply adding an aqueous or non-aqueous solution of a catalyst as descnbed herein to fabric which is stained, preferably the fabnc is in an aqueous solution when contacted with the catalyst. However, it is recognized that because of factors outside the control of the formulator inter aha source of product raw mateπals, unwanted decomposition of one or more ingredients, that a source of peroxygen may be introduced and/or formed unknowingly in the product. The compositions of the present invention do not require any peroxygen source, but the presence of any minor amounts will not effect the performance of the bleaching compositions described herein. Formulators may typically include a small amount of a source of hydrogen peroxide into compositions for the purposes of stabilizing enzymes, for example, a minor amount of perborate may be added. However, this amount of perborate is typically so minor that it has no effect on the bleaching capacity of the compositions of the present invention. In cases where the formulator has added a minor amount of an oxidant, or other source of peroxide for the purposes of stabilizing an adjunct ingredient, for the purposes of the present invention, those compositions are still defined as "substantially free" of a source of peroxygen as defined herein above if they do not provide additional bleaching activity on stains under typical use conditions. For example, a "substantially free" composition can include an amount of peroxygen source provided the degree to which the catalyst is effective is substantially the same as if the source of peroxygen were absent. For the purposes of the present invention, any composition which comprises less than 0.1%), preferably less than 0.01% of a primary oxidant, such as a pre-formed peracid or a source of hydrogen peroxide is considered "substantially free" as further defined herein above. Additionally, any laundry liquor, laundry wash water, pre-soak bath, or other fabπc or surface cleaning solution, wherein the present catalysts are used and which comprises less than 0.001% by weight of a source of peroxygen, pre-formed or otherwise formed in situ, is defined herein as "substantially free" as defined herein above. Stated otherwise, if the catalysts of the present invention are used to bleach stains on fabπc, or otherwise clean/bleach a hard surface or dishware, and the solution containing the catalyst has a concentration of a source of peroxygen less than 0.001% > , that solution is defined herein as "substantially free" of a source of peroxygen. Bleach Catalyst The compositions of the present invention compπse an effective amount of a bleach catalyst. The term "an effective amount" is defined as "an amount of the transition-metal bleach catalyst present in the present invention compositions, or during use according to the present invention methods, that is sufficient, under whatever comparative or use conditions are employed, to result m at least partial oxidation of the matenal sought to be oxidized by the composition or method." Typically the material to be oxidized is an unwanted substance inter aha food and beverage stains, greasy/oily stains, body soils on fabric, however, this is not the limitation to which the invention is applicable Oxidation in the absence of a source of peroxygen has wide applicability and the present invention is not limited solely to bleaching and/or cleaning of fabric. For example, automatic dishwashing compositions are an embodiment of the present invention wherein bleaching of a stam w ith a composition and/or with a solution which is "substantially free" of a source of peroxygen is a part of the present invention The same is equally true for hard surface cleaning compositions and solutions which comprise hard surface cleaning compositions which are "substantially free" of a source of peroxygen.

Formulations typically comprise from about 5% to about 50%, more typically about 5% to about 30%, by weight, of detergent builder. Granular formulations typically compnse from about 10% to about 80%, more typically from about 15% to about 50% > by weight, of the detergent builder. Lower or higher levels of builder, however, are not meant to be excluded. Inorganic or P-containmg detergent builders include, but are not limited to, the alkali metal, ammonium and alkanolammonium salts of polyphosphates (exemplified by the tπpolyphosphates, pyrophosphates, and glassy polymeric meta-phosphates), phosphonates, phytic acid, silicates, carbonates (including bicarbonates and sesquicarbonates), sulphates, and aluminosihcates. However, non-phosphate builders are required in some locales. Importantly, the compositions herein function surprisingly well even in the presence of the so-called "weak" builders (as compared with phosphates) such as citrate, or in the so-called "underbuilt" situation that may occur with zeolite or layered silicate builders. Examples of silicate builders are the alkali metal silicates described m U.S. 4,664,839 Rieck, issued May 12, 1987. NaSK.S-6 is the trademark for a crystalline layered silicate marketed by Hoechst (commonly abbreviated herein as "SKS-6"). Examples of carbonate builders are the alkaline earth and alkali metal carbonates as disclosed in German Patent Application No. 2,321,001 published on November 15, 1973. Alummosilicate builders are useful in the present invention. Examples of suitable alummosilicate builders are descnbed in U.S. 4,274,975 Corkhill et al. included herein by reference. Alummosilicate builders are of great importance in most currently marketed heavy duty granular detergent compositions, and can also be a significant builder ingredient in liquid detergent formulations. Alummosilicate builders include those having the empincal formula: [M z (zA10 2 ) y ] xH 2 0 wherein z and y are integers of at least 6, the molar ratio of z to y is in the range from 1.0 to about 0.5, and x is an integer from about 15 to about 264. Preferred synthetic crystalline alummosilicate ion exchange matenals useful herein are available under the designations Zeolite A, Zeolite P (B), Zeolite MAP and Zeolite X. Organic detergent builders suitable for the purposes of the present invention include, but are not restncted to, a wide vaπety of polycarboxylate compounds. As used herein, "polycarboxylate" refers to compounds having a plurality of carboxylate groups, preferably at least 3 carboxylates. Polycarboxylate builder can generally be added to the composition in acid form, but can also be added m the form of a neutralized salt. When utilized in salt form, alkali metals, such as sodium, potassium, and lithium, or alkanolammonium salts are preferred. Suitable are disclosed in U.S. 3,128,287 Berg, issued April 7, 1964, U.S. 3,635,830 Lamberti et al., issued January 18, 1972, U.S. 4,663,071 Bush et al., issued May 5, 1987, U.S. 3,923,679 Rapko, issued December 2, 1975; U.S. 4,158,635 Crutchfield et al., issued June 19, 1979; U.S. 4,120,874 Crutchfield et al., issued October 17, 1978; U.S. 4,566,984, Bush, issued January 28, 1986, U.S. 4,144,226, Crutchfield et al, issued March 13, 1979 and in U.S. 3,308,067, Diehl, issued March 7, 1967, Diehl U.S. Patent 3,723,322, and U.S. 4,102,903 Crutchfield et al., issued July 25, 1978 and further U.S Patents 3,159,581; 3,213,030; 3,422,021, 3,400,148 and 3,422,137. Citrate builders, e.g., citric acid and soluble salts thereof (particularly sodium salt), are polycarboxylate builders of particular importance for heavy duty liquid detergent formulations due to their availability from renewable resources and their biodegradabihty. Citrates can also be used m granular compositions, especially in combination with zeolite and/or layered silicate builders. Oxydisuccmates are also especially useful in such compositions and combinations.

Soluble acrylate/maleate copolymers of this type are known matenals which are described in European Patent Application No. 66915, published December 15, 1982, as well as m EP 193J60, published September 3, 1986, which also descnbes such polymers compπsing hydroxypropylacrylate. Still other useful dispersing agents include the maleic/acryhc/vinyl alcohol terpolymers. Such matenals are also disclosed m EP 193,360, including, for example, the 45/45/10 terpolymer of acry c/maleic/vmyl alcohol. Another polymenc matenal which can be included is polyethylene glycol (PEG). PEG can exhibit dispersing agent performance as well as act as a clay soil removal-antiredeposition agent. Typical molecular weight ranges for these purposes range from about 500 to about 100,000, preferably from about 1 ,000 to about 50,000, more preferably from about 1 ,500 to about 10,000. Polyaspartate and polyglutamate dispersing agents may also be used, especially in conjunction with zeolite builders. Dispersing agents such as polyaspartate preferably have a molecular weight (avg.) of about 10,000.

Purified or non-purified forms of these enzymes may be used. Nowadays, it is common practice to modify wild-type enzymes via protein / genetic engmeeπng techniques in order to optimize their performance efficiency in the laundry detergent and/or fabnc care compositions of the invention. For example, the variants may be designed such that the compatibility of the enzyme to commonly encountered ingredients of such compositions is increased. Alternatively, the variant may be designed such that the optimal pH, bleach or chelant stability, catalytic activity and the like, of the enzyme variant is tailored to suit the particular cleaning application In particular, attention should be focused on amino acids sensitive to oxidation m the case of bleach stability and on surface charges for the surfactant compatibility. The lsoelectnc point of such enzymes may be modified by the substitution of some charged amino acids, e.g. an increase in isoelectπc point may help to improve compatibility with aniomc surfactants. The stability of the enzymes may be further enhanced by the creation of e g. additional salt bndges and enforcing calcium binding sites to increase chelant stability. These optional detersive enzymes, when present, are normally incorporated in the cleaning composition at levels from 0.0001% to 2% of pure enzyme by weight of the cleaning composition. The enzymes can be added as separate single ingredients (pnlls, granulates, stabilized liquids, etc... containing one enzyme ) or as mixtures of two or more enzymes ( e.g. cogranulates ).

The following is a non-hmitmg example of the preparation of a bleach catalyst which effectively bleaches stains in the absence of a source of peroxygen. EXAMPLE 1 Synthesis of 5J2-dιmethyl-lJ,8J2-tetraaza-bιcvclof6.6J]hexadecane manganese (FT) chloride, having the formula: To a 250 mL, 3 necked round bottom flask, equipped with a thermometer, nitrogen inlet, and magnetic stirrer is added N,N'-bιs(2-amιnoethyl)-l J-propanedιamιne (5.00g, 31J mmol) and absolute ethanol (100 mL). The solution is stirred under argon and cooled to 15°C using an ice bath. Aqueous glyoxal (4.78 g., 33 mmol, 40% in water) is added dropwise with stirnng. Upon completion of the addition, the solution is concentrated under reduced pressure to yield a clear, colorless oil. The isolated oil has the formula 1 1 and is obtained in 100% yield (6.0 g). Cyclic amine 1 (6.0 g) is suspended in acetonitnle ( 100 mL). Potassium carbonate (25 g) and 1,3-propanediol ditosylate (12.61 g, 32.8 mmol) is added. The solution is stirred vigorously at RT overnight. The reaction is then warmed to 70°C and filtered hot with glass fiber filter paper and vacuum filtration. The resulting solid is washed with acetonitnle (100 mL). The acetonitnle filtrate is concentrated under reduced pressure to yield a light green oil having the formula 2: and is obtained in 100% yield (7.0 g). The tetraamine 2, (7.0 g) is dissolved in acetonitnle (150 mL). Methyl sulfate (2.5 equiv.) is added, the reaction warmed to 65°C and stirred for 9 days. The solvent is removed under reduced pressure to yield a brown oil having the formula 3 : and is obtained m approximately 85% yield. Distilled water (25 mL) and potassium carbonate (13.8 g) are added to a 250 mL round bottomed flask. Absolute ethanol (75 mL) is added and the resulting biphasic solution is stirred and heated to 60°C with an oil bath. Sodium borohydπde (1.60 g., 42J mmol) and 3 (10.0 g., 21J mmol) was added to the solution. The reaction is stirred at 60°C for 75 minutes. The reaction mixture is placed m a separatory funnel and the ethanol layer collected. The solvent is then removed under reduced pressure, the resulting tan solid/oil is dissolved m 5N KOH (5 mL) and extracted with toluene (2 x 50 mL). The toluene is removed under reduced pressure to yield 5J2-dιmethyl-l,5,8J2-tetraaza-bιcyclo[6.6J]hexadecane having the formula: as an oil, in 95% yield (5J g) after distillation. To a flame dried 12 liter, 3 neck round bottom flask equipped with a heating mantle, stir bar, and oven dried condenser is added anhydrous acetonitnle (5 liters) and yield 5,12-dιmethyl- l,5,8J2-tetraaza-bιcyclo[6.6J]hexadecane (484 gm., 1.9 moles). The milky white suspension is placed under a 10 mm vacuum until the suspension boiled and then the reaction vessel flushed with argon. This degassing is performed 7 times. After degassing is complete manganese (LI) chloride (228 gm, 1.81 moles) is added. After refluxing for 4 hours with vigorous stirπng, the suspension is immediately filtered through glass filter paper. The solvent is removed from the filtrate under reduced pressure at 45° C to yield a solid. The solid is then suspended in 500 ml. toluene, and the supernatant decanted off. This washing is repeated until the supernatant is free of color (typically 7 times with about 7X500 ml of toluene). The solid which remains I dried in vacuo to yield 575 g (84%) of 5J2-dιmethyl-l,5,8J2-tetraaza-bιcyclo[6.6J]hexadecane magnanese (II) chloride. A second crop of product is obtained by further washing of the solid material and subsequent treatment of the resulting solid in a like manner. Total yield is 636 g (93%) The following are non-limiting examples of Heavy Duty Liquid (HDL) laundry detergent compositions according to the present invention. TABLE I weight % 2.
