Description: MULTPLE-SUBSTITTJTED BLEACH ACTIVATORS FIELD OF THE INVENTION The present invention relates to bleaching compositions comprising multiple substituted bleach activator compounds comprising at least one tetravalent nitrogen. The compositions boost the performance of bleaching agents such as perborate. The multiple-substituted bleach activators are useful in fabric laundry and bleaching compositions, automatic dishwashing compositions, hard surface cleaners, bleach additives and the like. BACKGROUND OF THE INVENTION The formulation of detergent compositions which effectively remove a wide variety of soils and stains from fabrics under wide-ranging usage conditions remains a considerable challenge to the laundry detergent industry. Challenges are also faced by the formulator of automatic dishwashing detergent compositions (ADD's), which are expected to efficiently cleanse and sanitize dishware, often under heavy soil loads. The problems associated with the formulation of truly effective cleaning and bleaching compositions have been exacerbated by legislation which limits the use of effective ingredients such as phosphate builders in many regions of the world. Most conventional cleaning compositions contain mixtures of various detersive surfactants to remove a wide variety of soils and stains from surfaces. In addition, various detersive enzymes, soil suspending agents, non-phosphorus builders, optical brighteners, and the like may be added to boost overall cleaning performance. Many fully-formulated cleaning compositions contain oxygen bleach, which can be a perborate or percarbonate compound. While quite effective at high temperatures, perborates and percarbonates lose much of their bleaching function at the low to moderate temperatures increasingly favored in consumer product use. Accordingly, various bleach activators such as tetraacetylethylenediamine (TAED) and nonanoyloxybenzenesulfonate (NOBS) have been developed to potentiate the bleaching action of perborate and percarbonate across a wide temperature range. NOBS is particularly effective on "dingy" fabrics. Despite the use of TAED and NOBS in various cleaning and bleaching compositions, the search continues for more effective activator materials, especially for cleaning additional types of soils and surfaces. Improved activator materials should be safe, effective, and will preferably be designed to interact with troublesome soils and stains. Various cationically charged activators have been described in the literature. Many are esoteric and expensive. Some do not appear to be sufficiently compatible with anionic surfactants to allow their easy formulation into detergent compositions and yield a truly effective surfactant-plus-activated bleach system. The majority of cationic activators in the literature have a conjugate acid aqueous pK a value of the leaving-group which is below 13. It is generally accepted that bleach activators having leaving-groups with pK a values below 13 perhydrolyze at a desirable rate. It has now been determined that certain multiple-substituted bleach activators (MSBA's hereinafter) are unexpectedly effective in removing soils and stains from fabrics and hard surfaces such as dishes despite having a leaving-group conjugate acid aqueous pK a of greater than 13. These activators have advantageously high ratios of rates of perhydrolysis to hydrolysis and of perhydrolysis to diacylperoxide formation. Without being limited by theory, these unusual rate ratios lead to a number of significant benefits for the instant MSBA's, including increased efficiency, avoidance of wasteful byproduct formation in the wash, increased color compatibility, increased enzyme compatibility, and better stability on storage. Commercially attractive MSBA's are provided, for example through the use of caprolactam-based chemistry. The MSBA's herein are effective for removing soils and stains not only from fabrics, but also from dishware in automatic dishwashing compositions. The MSBA's function well over a wide range of washing or soaking temperatures and are safe on rubber surfaces, such as those of sump hoses often used in European front-loading washing-machines. In short, the MSBA's herein provide a substantial advance over activators known in the art, as will be seen from the disclosures hereinafter.

The present invention moreover encompasses peracid produced by reacting any of the aforementioned MSB As with hydrogen peroxide. Moieties X - When X is =O or =S, it is immediately apparent what structures are encompassed. When X is =N- however, the following structures further illustrate the MSBAs encompassed herein: er illustrated in the following embodiments: Leaving-groups - Preferred leaving-groups, L, in the MSB As herein include cyclic amidines with a ring size of from about 5 to about 12 atoms: Highly preferred cyclic amidines have a ring size of from about 5 to about 7 atoms as in the first three of the above structures. The invention also encompasses, by way of L, lactams with a ring size of from about 6 to about 12: Preferred lactam ring sizes are of from about 6 to about 7 atoms as in the first two of the above structures. In general, anilino derivatives are within the scope of allowable leaving- groups L herein. Such anilino derivatives are further illustrated as follows: which includes compounds Rl and R^ may be fused, e.g., Mixtures of leaving-groups are possible within the same MSBA, as illustrated hereinabove. Moreover, mixtures of any of the MSBAs with each other or with conventional bleach activators are quite acceptable for use in the instant bleaching compositions. Counter-anions - Preferred compositions of this invention comprise charge- balancing compatible anions or "counter-ions". In general, these may be monovalent, divalent, trivalent or polyvalent. Available anions such as bromide, chloride or phosphates may be used, though they may be other than preferred for one or another reason, such as bleach reactivity or phosphorus content. Preferred compatible anions are selected from the group consisting of sulfate, isethionate, alkanesulfonate, alkyl sulfate, aryl sulfonate, alkaryl sulfonate, carboxylates, polycarboxylates, and mixtures thereof. Preferred anions include the sulfonates selected from the group consisting of methanesulfonate, ethanesulfonate, benzenesulfonate, 7-toluenesulfonate, cumenesulfonate, xylenesulfonate, naphthalene sulfonate and mixtures thereof. Especially preferred of these sulfonates are those which contain aryl. Preferred alkyl sulfates include methyl sulfate and octyl sulfate. Preferred polycarboxylate anions suitable herein are nonlimitingly illustrated by terephthalate, polyacrylate, polymaleate, poly (acrylate-comaleate), or similar polycarboxylates; preferably such polycarboxylates have low molecular weights, e.g., 1,000 - 4,500. Suitable monocarboxylates are further illustrated by benzoate, naphthoate, p-toluate, and similar hard-water precipitation-resistant monocarboxylates. Electron-withdrawing substitutents - Bleaching compositions herein may comprise MSBAs comprising at least one electron-withdrawing or aromatic substituent in Q, such that the pKa of the peracid formed by the MSBA, e.g., QC(X)OOH, is less than the pK a of the nonsubstituted form. Preferably the electron- withdrawing substituent is neutral. More preferably the electron-withdrawing substituent is nitro, an aromatic moiety having an electron-withdrawing effect, or a combination of the two. The effects of electron withdrawing substituents on the aqueous pK a of aliphatic and aromatic peroxy acids are well understood and documented (see W. M. Richardson, in The Chemistry of the Functional Groups, Peroxides, Ed. S. Patai, Wiley, New York, 1983, Chapter 5, pp 130,131 and references therein). Without being limited by theory, it is believed that stronger peracids provide enhanced performance. Surface Activity of MSBA or Peracid - For bleaching compositions such as laundry detergent compositions herein, preferably the MSBA or peracid is surface- active, having a critical micelle concentration of less than or equal to about 10-2 molar. Such surface-active activators preferably comprise one long-chain moiety having a chain of from about 8 to about 12 atoms; the counter-ion is preferably non surface-active. The term "surface active" is well-known in the art and characterizes compounds which comprise at least one group with an affinity for the aqueous phase and, typically, a hydrocarbon chain with little affinity for water. Surface active compounds dissolved in a liquid, in particular in water, lower the surface tension or interfacial tension by positive adsorption at the liquid/vapor interface, or the soil- water interface. Critical micelle concentration (c m or "cmc"): is likewise a recognized term, referring to the characteristic concentration of a surface active material in solution above which the appearance and development of micelles brings about sudden variation in the relation between the concentration and certain physico- chemical properties of the solution. Said physico-chemical properties include density, electrical conductivity, surface tension, osmotic pressure, equivalent electrical conductivity and interfacial tension. Whereas high surface activity and low cmc is preferred in some applications of MSBA's, in other applications, such as cleaning of certain hydrophiiic soils, low surface activity and high cmc, e.g., about 10-1 molar or higher, may be desirable. Thus, in view of the range of applications contemplated, a wide range of cmc and surface activity for MSBA's is within the spirit and scope of the present invention. pK a . Rate and Perhvdrolvsis Criticalities - In accordance with the present invention, there are provided bleaching compositions wherein MSBAs are required to respect criticalities of pK a and criticalities relating to rates of perhydrolysis, hydrolysis and diacylperoxide formation. Furthermore, perhydrolysis effciency is important in selecting the MSBA. All of these criticalities will be better understood and appreciated in light of the following disclosure. pK a Value - The acids in which organic chemists have traditionally been interested span a range, from the weakest acids to the strongest, of about 60 pK units. Because no single solvent is suitable over such a wide range, establishment of comprehensive scales of acidity necessitates the use of several different solvents. Ideally, one might hope to construct a universal acidity scale by relating results obtained in different solvent systems to each other. Primarily because solute-solvent interactions affect acid-base equilibria diffently in different solvents, it has not proven possible to establish such a scale. Water is taken as the standard solvent for establishing an acidity scale. It is convenient, has a high dielectric constant, and is effective at solvating ions. Equilibrium acidities of a host of compounds (e.g., carboxylic acids and phenols) have been determined in water. Compilations of pK data may be found in Perrin, D. D. "Dissociation Constants of Organic Bases in Aqueous Solution"; Butterworths: London, 1965 and Supplement, 1973; Serjeant, E. P.; Dempsey, B. "Ionisation Constants of Organic Acids in Aqueous Solution"; 2nd ed., Pergammon Press: Oxford, 1979. Experimental methods for determining pK a values are described in the original papers. The pK a values that fall between 2 and 10 can be used with a great deal of confidence; however, the further removed values are from this range, the greater the degree of skepticism with which they must be viewed. For acids too strong to be investigated in water solution, more acidic media such as acetic acid or mixtures of water with perchloric or sulfuric acid are commonly employed; for acids too weak to be examined in water, solvents such as liquid ammonia, cyclohexylamine and dimethylsulfoxide have been used. The Hammett H 0 acidity function has allowed the aqueous acidity scale, which has a practical pK a range of about 0-12, to be extended into the region of negative pK a values by about the same range. The use of H_ acidity functions that employ strong bases and cosolvents has similarly extended the range upward by about 12 pK a units. The present invention involves the use of leaving groups the conjugate acids of which are considered to be weak; they possess aqueous pK a values greater than about 13. To establish only that a given compound has an aqueous pK a above about 13 is straightforward. As noted above, values much above this are difficult to measure with confidence without resorting to the use of an acidity function. While the measurement of the acidity of weak acids using the H_ method has the advantage of an aqueous standard state, it is restricted in that (1) it requires extrapolation across varying solvent media and (2) errors made in detemining indicator pK a values are cumulative. For these and other reasons, Bordwell and co-workers have developed a scale of acidity in dimethylsulfoxide (DMSO), and it is this scale which we use to define the upper limits of pK a for the conjugate acids of our leaving groups. This solvent has the advantage of a relatively high dielectric constant (ε = 47); ions are therefore dissociated so that problems of differential ion pairing are reduced. Although the results are referred to a standard state in DMSO instead of in water, a link with the aqueous pK a scale has been made. When acidities measured in water or on a water-based scale are compared with those measured in DMSO, acids whose conjugate bases have their charge localized are stronger acids in water; acids whose conjugate bases have their charge delocalized over a large area are usually of comparable strength. Bordwell details his findings in a 1988 article (Ace. Chem. Res. 1988, 2J f 456-463). Procedures for measurement of pK a in DMSO are found in papers referenced therein. Definitions of kft. kp. and kp - In the expressions given below, the choice of whether to use the concentration of a nucleophile or of its anion in the rate equation was made as a matter of convenience. One skilled in the art will realize that measurement of solution pH provides a convenient means of directly measuring the concentration of hydroxide ions present. One skilled in the art will further recognize that use of the total concentrations of hydrogen peroxide and peracid provide the most convenient means to determine the rate constants kp and kp. The terms, such as RC(O)L, used in the following definitions and in the conditions for the determination of kjj, kp and kpj, are illustrative of a general bleach activator structure and are not limiting to any specific bleach activator structure herein. Specifically, the term "RC(O)L" could be substituted with "QC(O)L" or "QC(X)L", etc. Definition of ^ RC(O)L + HO " → RC(O)O " + HL The rate of the reaction shown above is given by Rate = kH[RC(O)L][HO The rate constant for hydrolysis of bleach activator (kjj) is the second order rate constant for the bimoiecular reaction between bleach activator and hydroxide anion as determined under the conditions specified below. Definition of kp RC(O)L + H 2 O 2 → RC(O)O 2 H + HL The rate of the reaction shown above is given by Rate = kp[RC(O)L][H 2 O ]τ where [H2θ2Jτ represents the total concentration of hydrogen peroxide and is equal to [H2O2] + [HO2~]- The rate constant for perhydrolysis of bleach activator (kp) is the second order rate constant for the bimoiecular reaction between bleach activator and hydrogen peroxide as determined under the conditions specified below. Definition of kp RC(O)L + RC(O)O 2 H → RC(O)O 2 C(O)R + HL The rate of the reaction shown above is given by Rate = k D .[RC(O)L][RC(O)O 2 H] τ where [RC(O)O2H] represents the total concentration of peracid and is equal to [RC(O)O 2 H] + [RC(O)O 2 ~ ]. The rate constant for the formation of a diacylperoxide from the bleach activator (kp), the second order rate constant for the bimoiecular reaction between bleach activator and peracid anion, is calculated from the above defined kp>. The value for kp* is determined under the conditions specified below. Conditions for the Determination of Rate Constants Hydrolysis - A set of experiments is completed to measure the rate of hydrolysis of a bleach activator RC(O)L in aqueous solution at total ionic strength of IM as adjusted by addition of NaCl. The temperature is maintained at 35.0 ± 0.1 °C and the solution is buffered with NaHCO3 + Na2CU3. A solution of the activator ([RC(O)L] = 0.5 mM) is reacted with varying concentrations of NaOH under stopped-flow conditions and the rate of reaction is monitored optically. Reactions are run under pseudo first-order conditions to determine the bimoiecular rate constant for hydrolysis of bleach activator (lcj-j). Each kinetic run is repeated at least five times with about eight different concentrations of hydroxide anions. All kinetic traces give satisfactory fits to a first-order kinetic rate law and a plot of the observed first-order rate constant versus concentration of hydroxide anion is linear over the region investigated. The slope of this line is the derived second order rate constant kj-j. Perhvdrolvsis - A set of experiments is completed to measure the rate of perhydrolysis of a bleach activator RC(O)L in aqueous solution at pH - 10.0 with constant ionic strength of IM as adjusted by addition of NaCl. The temperature is maintained at 35.0 ± 0.1 °C and the solution is buffered with NaHCO3 + Na 2 Cθ3. A solution of the activator ([RC(O)L] = 0.5 mM) is reacted with varying concentrations of sodium perborate under stopped-flow conditions and the rate of reaction is monitored optically. Reactions are run under pseudo first-order conditions in order to determine the bimoiecular rate constant for perhydrolysis of bleach activator (kp). Each kinetic run is repeated at least five times with about eight different concentrations of sodium perborate. All kinetic traces give satisfactory fits to a first-order kinetic rate law and a plot of the observed first- 20 order rate constant versus total concentration of hydrogen peroxide is linear over the region investigated. The slope of this line is the derived second order rate constant kp. One skilled in the art recognizes that this rate constant is distinct from, but related to, the second order rate constant for the reaction of a bleach activator with the anion of hydrogen peroxide ( -mic) The relationship of these rate constants is given by the following equation: - kp {(κ a + iH ]yκ t } where K a is the acid dissociation constant for hydrogen peroxide. Formation of diacylperoxide - A set of experiments is completed to measure the rate of formation of a diacylperoxide RC(O)O2C(O)R from a bleach aαivator RC(O)L in aqueous solution at pH = 10.0 with constant ionic strength of IM as adjusted by addition of NaCl. The temperature is maintained at 35.0 ± 0.1 °C and the solution is buffered with NaHCO3 + Na2CO3. A solution of the activator ([RC(O)L] = 0.5 mM) is reacted with varying concentrations of peracid under stopped-flow conditions and the rate of reaction is monitored optically. Reactions are run under pseudo first-order conditions in order to determine the bimoiecular rate constant kp>. Each kinetic run is repeated at least five times with about eight different concentrations of peracid anion. All kinetic traces give satisfactory fits to a first-order kinetic rate law and a plot of the observed first-order rate constant versus total concentration of peracid is linear over the region investigated. The slope of this line is the derived second order rate constant kp<. The bimoiecular rate constant for the formation of a diacylperoxide from peracid anion (kp) is calculated according to where K a is the acid dissociation constant for the peracid RC(O)O2H. One skilled in the art will realize that the pK a values for peracids fall into a rather narrow range from about 7 to about 8.5 and that at pH = 10.0, when K a ≥ about 10~ 8 , {(K a + [H+]yK a } ≡ 1 and kp = kp.. Test for Perhvdrolvsis Efficiency - This method is applicable as a test for screening any bleach activators RC(O)L (not intending to be limiting of any specific MSBA structure herein) by confirmation of the formation of peracid analyte RC(O)O2H. The minimum standard for perhydrolysis efficiency (PE) is the generation of ≥10%, preferably >20%, of theoretical peracid within 10 minutes when tested under the conditions specified below. Test Conditions - Distilled, deionized water at 40 °C adjusted to pH = 10.3 with Na2CO3, 100 ppm bleach activator RC(O)L, 500 ppm sodium percarbonate Test Protocol - Distilled, deionized water (90 mL; pH adjusted to 10.3 with Na2CO3) is added to a 150 mL beaker and heated to 40 ± 1 °C. Fifty (50) mg sodium percarbonate is added to the beaker and the mixture is stirred two minutes before a 10 mL solution containing 10 mg of bleach activator (predissolved in 1 mL of a water miscible organic solvent (e.g., methanol or dimethylformamide) and brought to volume with pH 10.3 distilled, deionized water) is added. The initial time point is taken 1 minute thereafter. A second sample is removed at 10 minutes. Sample aliquots (2 mL) are examined via analytical HPLC for the quantitative determination of peracid RC(O)O2H. Sample aliquots are individually mixed with 2 mL of a pre-chiUed 5 °C solution of acetonitrile/acetic acid (86/14) and placed in temperature controlled 5 ° C autosampler for subsequent injection onto the HPLC column. High performance liquid chromatography of the authentic peracid under a given set of conditions establishes the characteristic retention time (rp for the analyte. Conditions for the chromatography will vary depending on the peracid of interest and should be chosen so as to allow baseline separation of the peracid from other analytes. A standard calibration curve (peak area vs. concentration) is constructed using the peracid of interest. The analyte peak area of the 10 minute sample from the above described test is thereby converted to ppm peracid generated for determination of the quantity PE. A bleach activator is considered acceptable when a value of PE = [(ppm of peracid generated)/(theoretical ppm peracid)] x 100% ≥ 10% is achieved within ten minutes under the specified test conditions. Note, by comparison with 4,5-saturated cyclic amidine embodiments of the instant bleach activators, known related chemical compounds wherein the 4,5 position is unsaturated have surprisingly greater rates of hydrolysis. Specifically, acetyl imidazole has kjj, greater than ; ϋ 0 M"l s"l. Accordingly this invention does not encompass imidε 1« as a leaving r ../..p. Determination of krø, kp and kp when the MSBA has formula O(C(Xιl t wherein t > 1: or has formula L'(C(X)Q)^ The present invention comprises MSBA embodiments wherein there are single or multiple -C(X)L groups. When only a single -C(X)L moiety is present, measurement of kj-j, kp and kp is accomplished straightforwardly as described hereinabove. When the MSBA comprises multiple -C(X)L or multiple -C(X)Q groups, those skilled in the art will realize that the determination of kjj, kp and kp for such bleach activators is best accomplished through the use of model compounds. "Model compounds" herein are chemical compounds identified purely for purposes of simplifying testing and measurement, and are not required to lie within the instant invention (though they may in certain instances do so). The formula of model compounds is generally arrived at by replacing all but one of the -C(X)L or -C(X)Q moieties in any multiple -C(X)L or multiple -C(X)Q -containing MSBA with methyl or H. A number of different cases are identified, depending on the precise formula of the MSBA: For bleach activators of formula Q(C(X)L)t wherein t > 1: Case (i) a When Q is symmetric and all C(X)L groups are identical, a single model compound is required. Case (i)° When Q is symmetric and all C(X)L groups are not identical, t model compounds are needed. Case (i) c When Q is asymmetric, t model compounds are needed regardless of whether or not all C(X)L groups are identical. For bleach activators of formula L'(C(X)Q>y: Case (ϋ) a When L' is symmetric and all C(X)Q groups are identical, a single model compound is required. Case (ϋ) D When L' is symmetric and all C(X)Q groups are not identical, f model compounds are needed. Case (ϋ) c When L' is asymmetric, t' model compounds are needed regardless of whether or not all C(X)Q groups are identical. The choice of suitable model compounds is nonlimitingly illustrated as follows. Examples of each case described above are illustrated below. A model compound for the above is Two model compounds for the above are: and Case (i) c Model compounds for the above are and A model compound for the above is: Model compounds for the above are and Model compounds for the above are: and The above examples are given by way of illustration. One skilled in the art will realize that if the connection between any two -C(X)L (or -C(X)Q) is conjugated, any electronic effect of one -C(X)L (or -C(X)Q) on the kinetics of the other must be suitably accounted for in the model compounds chosen. When model compounds have been selected for a multiple -C(X)L or multiple -C(X)Q -containing MSBA, kjj, kp and kp are measured for each model compound as described hereinabove. The bleach activator corresponding to the set of model compounds is considered to conform with the kp/lqj, kp/kp and krr-j criticalities of the invention provided that all model compounds meet the specified kp/kjj, kp kp and jj criticalities. Bleaching Compositions - The MSBAs herein are not preferably employed alone but in combination with a source of hydrogen peroxide, as disclosed hereinafter. Levels of the MSBAs herein may vary widely, e.g., from about 0.05% to about 95%, by weight, of composition, although lower levels, e.g., from about 0.1% to about 20% are more typically used. Source of hydrogen peroxide - A source of hydrogen peroxide herein is any convenient compound or mixture which under consumer use conditions provides an effective amount of hydrogen peroxide. Levels may vary widely and are typically from about 0.5% to about 60%, more typically from about 0.5% to about 25%, by weight of the bleaching compositions herein. The source of hydrogen peroxide used herein can be any convenient source, including hydrogen peroxide itself. For example, perborate, e.g., sodium perborate (any hydrate but preferably the mono- or tetra-hydrate), sodium carbonate peroxyhydrate or equivalent percarbonate salts, sodium pyrophosphate peroxyhydrate, urea peroxyhydrate, or sodium peroxide can be used herein. Mixtures of any convenient hydrogen peroxide sources can also be used. A preferred percarbonate bleach comprises dry particles having an average particle size in the range from about 500 micrometers to about 1,000 micrometers, not more than about 10% by weight of said particles being smaller than about 200 micrometers and not more than about 10% by weight of said particles being larger than about 1,250 micrometers. Optionally, the percarbonate can be coated with silicate, borate or water-soluble surfactants. Percarbonate is available from various commercial sources such as FMC, Solvay and Tokai Denka. While effective bleaching compositions herein may comprise only the MSBAs of the invention and a source of hydrogen peroxide, fully-formulated laundry and automatic dishwashing compositions typically will further comprise adjunct ingredients to improve or modify performance. Typical, non-limiting examples of such ingredients are disclosed hereinafter for the convenience of the formulator. Adjunct Ingredients Bleach catalysts - If desired, the bleaches can be catalyzed by means of a manganese compound. Such compounds are well known in the art and include, for example, the manganese-based catalysts disclosed in U.S. Pat. 5,246,621, U.S. Pat. 5,244,594; U.S. Pat. 5,194,416; U.S. Pat. 5,114,606; and European Pat.

Other metal-based bleach catalysts include those disclosed in U.S. Pat. 4,430,243 and U.S. Pat. 5,114,611. The use of manganese with various complex ligands to enhance bleaching is also reported in the following United States Patents: 4,728,455; 5,284,944; 5,246,612; 5,256,779; 5,280,117; 5,274,147; 5,153,161; and 5,227,084. Said manganese can be precomplexed with ethylenediaminedisuccinate or separately added, for example as a sulfate salt, with ethylenediaminedisuccinate. (See U.S. Application Ser. No. 08/210,186, filed March 17, 1994.) Other preferred transition metals in said transition-metal-containing bleach catalysts include iron or copper. As a practical matter, and not by way of limitation, the bleaching compositions and processes herein can be adjusted to provide on the order of at least one part per ten million of the active bleach catalyst species in the aqueous washing liquor, and will preferably provide from about 0.1 ppm to about 700 ppm, more preferably from about 1 ppm to about 50 ppm, of the catalyst species in the laundry liquor. Conventional Bleach Activators - "Conventional bleach activators" herein are any bleach activators which do not respect the above-identified provisions given in connection with the MSBAs. Numerous conventional bleach activators are known and are optionally included in the instant bleaching compositions. Various nonlimiting examples of such activators are disclosed in U.S. Patent 4,915,854, issued April 10, 1990 to Mao et al, and U.S. Patent 4,412,934. The nonanoyloxybenzene sulfonate (NOBS) and tetraacetyl ethylenediamine (TAED) activators are typical, and mixtures thereof can also be used. See also U.S. 4,634,551 for other typical conventional bleach activators. Known amido-derived bleach activators are those of the formulae: RlN(R 5 )C(O)R 2 C(O)L or RlC(O)N(R 5 )R 2 C(O)L wherein Rl is an alkyl group containing from about 6 to about 12 carbon atoms, R 2 is an alkylene containing from 1 to about 6 carbon atoms, R^ is H or alkyl, aryl, or alkaryl containing from about 1 to about 10 carbon atoms, and L is any suitable leaving group. Further illustration of optional, conventional bleach activators of the above formulae include (6- octanamido-caproyl)oxybenzenesulfonate, (6-nonanamidocaproyl)oxybenzenesul- fonate, (6-decanamido-caproyl)oxybenzenesulfonate, and mixtures thereof as described in U.S. Patent 4,634,551. Another class of conventional bleach activators comprises the benzoxazin-type activators disclosed by Hodge et al in U.S. Patent 4,966,723, issued October 30, 1990. Still another class of conventional bleach activators includes those acyl lactam activators which do not contain any cationic moiety, such as acyl caprolactams and acyl valerolactams of the formulae RόC(O)Ll and R6C(O)L2 wherein R 6 is H, an alkyl, aryl, alkoxyaryl, or alkaryl group containing from 1 to about 12 carbon atoms, or a substituted phenyl group containing from about 6 to about 18 carbons and wherein Ll and Z are caprolactam or valerolactam moieties. See copending U.S. applications 08/064,562 and 08/082,270, which disclose substituted benzoyl lactams. Highly preferred lactam activators include benzoyl caprolactam, octanoyl caprolactam, 3,5,5-trimethylhexanoyl caprolactam, nonanoyl caprolactam, decanoyl caprolactam, undecenoyl caprolactam, benzoyl valerolactam, octanoyl valerolactam, decanoyl valerolactam, undecenoyl valerolactam, nonanoyl valerolactam, 3,5,5-trimethylhexanoyl valerolactam and mixtures thereof. See also U.S. Patent 4,545,784, issued to Sanderson, October 8, 1985, which discloses acyl caprolactams, including benzoyl caprolactam, adsorbed into sodium perborate. Bleaching agents other than hydrogen peroxide sources are also known in the art and can be utilized herein as adjunct ingredients. One type of non-oxygen bleaching agent of particular interest includes photoactivated bleaching agents such as the sulfonated zinc and/or aluminum phthalocyanines. See U.S. Patent 4,033,718, issued July 5, 1977 to Holcombe et al. If used, detergent compositions will typically contain from about 0.025% to about 1.25%, by weight, of such bleaches, especially sulfonated zinc phthaiocyanine. Organic Peroxides, especially Diacyl Peroxides - are extensively illustrated in Kirk Othmer, Encyclopedia of Chemical Technology, Vol. 17, John Wiley and Sons, 1982 at pages 27-90 and especially at pages 63-72, all incorporated herein by reference. Suitable organic peroxides, especially diacyl peroxides, are further illustrated in "Initiators for Polymer Production", Akzo Chemicals Inc., Product Catalog, Bulletin No. 88-57, incorporated by reference. Preferred diacyl peroxides herein whether in pure or formulated form for granule, powder or tablet forms of the bleaching compositions constitute solids at 25°C , e.g., CADET® BPO 78 powder form of dibenzoyl peroxide, from Akzo. Highly preferred organic peroxides, particularly the diacyl peroxides, for such bleaching compositions have melting points above 40°C, preferably above 50°C. Additionally, preferred are the organic peroxides with SADPs (as defined in the foregoing Akzo publication) of 35°C or higher, more preferably 70°C or higher. Nonlimiting examples of diacyl peroxides useful herein include dibenzoyl peroxide, lauroyl peroxide, and dicumyl peroxide. Dibenzoyl peroxide is preferred. In some instances, diacyl peroxides are available in the trade which contain oily substances such as dioctyl phthalate. In general, particularly for automatic dishwashing applications, it is preferred to use diacyl peroxides which are substantially free from oily phthalates since these can form smears on dishes and glassware. Conventional Quaternary Substituted Bleach Activators - The present compositions can optionally further comprise conventional, known quaternary substituted bleach activators (CQSBA). CQSBA's are further illustrated in U.S. 4,539,130, Sept. 3, 1985 and U.S. Pat. No. 4,283,301. British Pat. 1,382,594, published Feb. 5, 1975, discloses a class of CQSBA's optionally suitable for use herein. U.S. 4,818,426 issued Apr. 4., 1989 discloses another class of CQSBA's. Also see U.S. 5,093,022 issued March 3, 1992 and U.S. 4,904,406, issued Feb. 27, 1990. Additionally, CQSBA's are described in EP 552,812 Al published July 28, 1993, and in EP 540,090 A2, published May 5, 1993. Particularly preferred are CQSBA's having a caprolactam or valerolactam leaving group, and are the subject of copending applications, in particular co-pending commonly assigned British Patent Appl. Ser. No. 9407944.9, filed April 21, 1994, P&G Case No. CM705F. Detersive Surfactants - Nonlimiting examples of surfactants useful herein include the conventional Cu.Ci g alkylbenzene sulfonates ("LAS") and primary, branched-chain and random C10-C20 alkyl sulfates ("AS"), the CiQ-Cjg secondary (2,3) alkyl sulfates of the formula CH 3 (CH2)χ(CHOSθ3-M + )CH3 and CH3(CH2)y(CHOSO3-M + ) CH2CH3 where x and (y + 1) are integers of at least about 7, preferably at least about 9, and M is a water-solubilizing cation, especially sodium, unsaturated sulfates such as oleyl sulfate, the Cjo-Cjg alkyl alkoxy sulfates ( M AEχS"; especially EO 1-7 ethoxy sulfates), Cjo-Cig alkyl alkoxy carboxylates (especially the EO 1-5 ethoxycarboxylates), the Cio-Ciβ glycerol ethers, the CIQ- Ci g alkyl polyglycosides and their corresponding sulfated polyglycosides, and C12- Ci g alpha-sulfonated fatty acid esters. If desired, the conventional nonionic and amphoteric surfactants such as the C^-Cjg alkyl ethoxylates ("AE") including the so-called narrow peaked alkyl ethoxylates and C6-C12 alkyl phenol alkoxylates (especially ethoxylates and mixed ethoxylate/propoxylates), C^-Cjg betaines and sulfobetaines ("sultaines"), Cιo~C|g amine oxides, and the like, can also be included in the overall compositions. The Cjo-Cig N-alkyl polyhydroxy fatty acid amides can also be used. Typical examples include the C12-C18 N-methylglucamides. See WO 9,206,154. Other sugar-derived surfactants include the N-alkoxy polyhydroxy fatty acid amides, such as C10-C18 N-(3-methoxypropyl) glucamide. The N-propyl through N-hexyl Ci2~Cι g glucamides can be used for low sudsing. C10-C20 conventional soaps may also be used. If high sudsing is desired, the branched-chain C10-C16 soaps may be used. Mixtures of anionic and nonionic surfactants are especially useful. Automatic dishwashing compositions typically employ low sudsing surfactants, such as the mixed ethyleneoxy/propyleneoxy nonionics. Other conventional useful surfactants are listed in standard texts. Builders - Detergent builders can optionally be included in the compositions herein to assist in controlling mineral hardness. Inorganic as well as organic builders can be used. Builders are typically used in automatic dishwashing and fabric laundering compositions to assist in the removal of paniculate soils. The level of builder can vary widely depending upon the end use of the composition and its desired physical form. When present, the compositions will typically comprise at least about 1% builder. High performance compositions typically comprise 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 excluded. Inorganic or P-containing detergent builders include, but are not limited to, the alkali metal, ammonium and alkanolammonium salts of polyphosphates (exemplified by the tripolyphosphates, pyrophosphates, and glassy polymeric meta- phosphates), phosphonates, phytic acid, silicates, carbonates (including bicarbonates and sesquicarbonates), sulphates, and aluminosilicates. 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. For examples of preferred aluminosilicates see U.S. Pat. 4,605,509. Examples of silicate builders are the alkali metal silicates, particularly those having a SiO2:Na2O ratio in the range 1.6:1 to 3.2:1 and layered silicates, such as the layered sodium silicates described in U.S. Patent 4,664,839, issued May 12, 1987 to H. P. Rieck. NaSKS-6® is a crystalline layered silicate marketed by Hoechst (commonly abbreviated herein as "SKS-6"). Unlike zeolite builders, the Na SKS-6 silicate builder does not contain aluminum. NaSKS-6 is the δ-Na2Siθ5 morphology form of layered silicate and can be prepared by methods such as those described in German DE-A-3,417,649 and DE-A-3,742,043. SKS-6 is a highly preferred layered silicate for use herein, but other such layered silicates, such as those having the general formula NaMSi x θ2 χ +ryH2θ wherein M is sodium or hydrogen, x is a number from 1.9 to 4, preferably 2, and y is a number from 0 to 20, preferably 0 can be used herein. Various other layered silicates from Hoechst include NaSKS-5, NaSKS-7 and NaSKS-11, as the α-, β- and γ- forms. Other silicates may also be useful, such as for example magnesium silicate, which can serve as a crispening agent in granular formulations, as a stabilizing agent for oxygen bleaches, and as a component of suds control systems. Silicates useful in automatic dishwashing (ADD) applications include granular hydrous 2-ratio silicates such as BRITESIL® H20 from PQ Corp., and the commonly sourced BRITESIL® H24 though liquid grades of various silicates can be used when the ADD composition has liquid form. Within safe limits, sodium metasilicate or sodium hydroxide alone or in combination with other silicates may be used in an ADD context to boost wash pH to a desired level. 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. Various grades and types of sodium carbonate and sodium sesquicarbonate may be used, certain of which are particularly useful as carriers for other ingredients, especially detersive surfactants. Aluminosilicate builders are useful in the present invention. Aluminosilicate 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. Aluminosilicate builders include those having the empirical formula: [M z (zAlθ2)y] H2O 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. Useful aluminosilicate ion exchange materials are commercially available. These aluminosilicates can be crystalline or amorphous in structure and can be naturally-occurring aluminosilicates or synthetically derived. A method for producing aluminosilicate ion exchange materials is disclosed in U.S. Patent 3,985,669, Knimmel, et al, issued October 12, 1976. Preferred synthetic crystalline aluminosilicate ion exchange materials useful herein are available under the designations Zeolite A, Zeolite P (B), Zeolite MAP and Zeolite X. In an especiaUy preferred embodiment, the crystalline aluminosilicate ion exchange material has the formula: Nai2[(Alθ2)i2(Siθ2)i2] xH2θ wherein x is from about 20 to about 30, especially about 27. This material is known as Zeolite A. Dehydrated zeolites (x = 0 - 10) may also be used herein. Preferably, the aluminosilicate has a particle size of about 0.1-10 microns in diameter. As with other builders such as carbonates, it may be desirable to use zeolites in any physical or morphological form adapted to promote surfactant carrier function, and appropriate particle sizes may be freely selected by the formulator. Organic detergent builders suitable for the purposes of the present invention include, but are not restricted to, a wide variety 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 in the form of a neutralized salt or "overbased". When utilized in salt form, alkali metals, such as sodium, potassium, and lithium, or alkanolammonium salts are preferred. Included among the polycarboxylate builders are a variety of categories of useful materials. One important category of polycarboxylate builders encompasses the ether polycarboxylates, including oxydisuccinate, as disclosed in Berg, U.S. Patent 3,128,287, issued April 7, 1964, and Lamberti et al, U.S. Patent 3,635,830, issued January 18, 1972. See also "TMS/TDS" builders of U.S. Patent 4,663,071, issued to Bush et al, on May 5, 1987. Suitable ether polycarboxylates also include cyclic compounds, particularly alicyclic compounds, such as those described in U.S. Patents 3,923,679; 3,835,163; 4,158,635; 4,120,874 and 4,102,903. Other useful detergency builders include the ether hydroxypolycarboxylates, copolymers of maleic anhydride with ethylene or vinyl methyl ether, 1, 3, 5- trihydroxy benzene-2, 4, 6-trisulphonic acid, and carboxymethyloxysuccinic acid, the various alkali metal, ammonium and substituted ammonium salts of polyacetic acids such as ethylenediaminetetraacetic acid and nitrilotriacetic acid, as well as polycarboxylates such as mellitic acid, succinic acid, oxydisuccmic acid, polymaleic acid, benzene 1,3,5-tricarboxylic acid, carboxymethyloxysuccinic acid, and soluble salts thereof. Citrate builders, e.g., citric acid and soluble salts thereof (particularly sodium salt), are polycarboxylate builders of particular importance for heavy duty laundry detergent formulations due to their availability from renewable resources and their biodegradability. Citrates can also be used in combination with zeolite and/or layered silicate builders. Oxydisuccinates are also especially useful in such compositions and combinations. Also suitable in the detergent compositions of the present invention are the 3,3-dicarboxy-4-oxa-l,6-hexanedioates and the related compounds disclosed in U.S. Patent 4,566,984, Bush, issued January 28, 1986. Useful succinic acid builders include the C5-C20 alkyl and alkenyl succinic acids and salts thereof. A particularly preferred compound of this type is dodecenylsuccinic acid. Specific examples of succinate builders include: laurylsuccinate, myristylsuccinate, palmitylsuccinate, 2- dodecenylsuccinate (preferred), 2-pentadecenylsuccinate, and the like. Laurylsuccinates are the preferred builders of this group, and are described in European Patent Application 86200690.5/0,200,263, published November 5, 1986. Other suitable polycarboxylates are disclosed in U.S. Patent 4,144,226, Crutchfield et al, issued March 13, 1979 and in U.S. Patent 3,308,067, Diehl, issued March 7, 1967. See also U.S. Patent 3,723,322. Fatty acids, e.g., C12-C18 monocarboxylic acids, can also be incorporated into the compositions alone, or in combination with the aforesaid builders, especially citrate and/or the succinate builders, to provide additional builder aαivity. Such use of fatty acids will generally result in a diminution of sudsing, which should be taken into account by the formulator. In situations where phosphorus-based builders can be used, and especially in the formulation of bars used for hand-laundering operations, the various alkali metal phosphates such as the well-known sodium tnpolyphosphates, sodium pyrophosphate and sodium orthophosphate can be used. Phosphonate builders such as ethane- 1 - hydroxy-l,l-diphosphonate and other known phosphonates (see, for example, U.S. Patents 3,159,581; 3,213,030; 3,422,021; 3,400,148 and 3,422,137) can also be used. Chelating Agents - The compositions herein may also optionally contain one or more iron and/or manganese chelating agents, such as hydroxyethyldiphosphonate (HEDP). More generally, chelating agents suitable for use herein can be seleαed from the group consisting of aminocarboxylates, aminophosphonates, polyfunctionally-substituted aromatic chelating agents and mixtures thereof. Without intending to be bound by theory, it is believed that the benefit of these materials is due in part to their exceptional ability to remove iron and manganese ions from washing solutions by formation of soluble chelates; other benefits include inorganic film or scale prevention. Other suitable chelating agents for use herein are the commercial DEQUEST® series, and chelants from Nalco, Inc. Aminocarboxylates useful as optional chelating agents include ethylenediaminetetracetates, N-hydroxyethylethylenediaminetriacetates, nitrilotriacetates, ethylenediamine tetraproprionates, triethylenetetraaminehexacetates, diethylenetriamine-pentaacetates, and ethanoidiglycines, alkali metal, ammonium, and substituted ammonium salts therein and mixtures therein. Aminophosphonates are also suitable for use as chelating agents in the compositions of the invention when at least low levels of total phosphorus are permitted in detergent compositions, and include ethylenediaminetetrakis (mαhylenephosphonates). Preferably, these aminophosphonates do not contain alkyl or alkenyl groups with more than about 6 carbon atoms. Polyfunctionally-substituted aromatic chelating agents are also useful in the compositions herein. See U.S. Patent 3,812,044, issued May 21, 1974, to Connor et al. Preferred compounds of this type in acid form are dihydroxydisuifobenzenes such as l,2-dihydroxy-3,5-disulfobenzene. A highly preferred biodegradable chelator for use herein is ethylenediamine disuccinate ("EDDS"), especially (but not limited to) the [S,S] isomer as described in U.S. Patent 4,704,233, November 3, 1987, to Hartman and Perkins. The trisodium salt is preferred though other forms, such as Magnesium salts, may also be useful. If utilized, especially in ADD compositions, these chelating agents or transition-metal-selective sequestrants will preferably comprise from about 0.001% to about 10%, more preferably from about 0.05% to about 1% by "weight of the bleaching compositions herein. Enzvmes - Enzymes can be included in the formulations herein for a wide variety of fabric laundering or other cleaning purposes, including removal of protein- based, carbohydrate-based, or triglyceride-based stains, for example, and for the prevention of refugee dye transfer, and for fabric restoration. The enzymes to be incorporated include proteases, amylases, Upases, ceUulases, and peroxidases, as well as mixtures thereof Other types of enzymes may also be included. They may be of any suitable origin, such as vegetable, animal, baαerial, fungal and yeast origin. However, their choice is governed by several faαors such as pH-actrvity and/or stabUity optima, thermostabiUty, stabiUty versus active dαergents, buUders, etc.. In this respeα baαerial or fiingal enzymes are preferred, such as baαerial amylases and proteases, and fiingal ceUulases. Enzymes are normally incorporated at levels sufficient to provide up to about 5 mg by weight, more typically about 0.01 mg to about 3 mg, of aαive enzyme per gram of the composition. Stated otherwise, the compositions herein will typically comprise from about 0.001% to about 5%, preferably 0.01%-1% by weight of a commercial enzyme preparation. Protease enzymes are usuaUy present in such commercial preparations at levels sufficient to provide from 0.005 to 0.1 Anson units (AU) of aαivity per gram of composition. Suitable examples of proteases are the subtilisins which are obtained from particular strains of B. subtilis and B. licheniformis. Another suitable protease is obtained from a strain of Bacillus, having maximum aαivity throughout the pH range of 8-12, developed and sold by Novo Industries A/S as ESPERASE®. The preparation of this enzyme and analogous enzymes is described in British Patent Specification No. 1,243,784 of Novo. Proteolytic enzymes suitable for removing protein-based stains that are commercially available include those sold under the tradenames ALCALASE® and SAVINASE® by Novo Industries A/S (Denmark) and MAXATASE® by International Bio-Synthetics, Inc. (The Netherlands). Other proteases include Protease A (see European Patent AppUcation 130,756, pubUshed January 9, 1985) and Protease B (see European Patent AppUcation Serial No. 87303761.8, filed April 28, 1987, and European Patent AppUcation 130,756, Bott et al, pubUshed January 9, 1985). An especiaUy preferred protease, referred to as "Protease D" is a carbonyl hydrolase variant having an amino acid sequence not found in nature, which is derived from a precursor carbonyl hydrolase by substituting a different amino acid for a plurality of amino acid residues at a position in said carbonyl hydrolase equivalent to position +76 in combination with one or more amino acid residue positions equivalent to those seleαed from the group consisting of +99, +101, +103, +107 and +123 in Bacillus amyloliquefaciens subtiUsin as described in the patent applications of A. Baeck, C.K. Ghosh, P.P. Greycar, R.R. Bott and L.J. WUson, entitled "Protease-Containing Cleaning Compositions" having U.S. Serial No. 08/136,797 (P&G Case 5040), and "Bleaching Compositions Comprising Protease Enzymes" having U.S. Serial No. 08/136,626. Amylases include, for example, α-amylases described in British Patent Specification No. 1,296,839 (Novo), RAPID ASE®, International Bio-Synthrtics, Inc. and TERMAMYL®, Novo Industries. CeUulases usable in the present invention include both baαerial or fiingal ceUulases. Preferably, they will have a pH optimum of between 5 and 9.5. Suitable ceUulases are disclosed in U.S. Patent 4,435,307, Barbesgoard et al, issued March 6, 1984, which discloses fungal cellulase produced from Humicola insolens and Humicola strain DSM1800 or a cellulase 212-producing fungus belonging to the genus Aeromonas, and ceUulase extracted from the hepatopancreas of a marine moUusk (Dolabella Auricula Solander). Suitable ceUulases are also disclosed in GB- A-2.075.028; GB-A-2.095.275 and DE-OS-2.247.832. CAREZYME® (Novo) is especially useful. Suitable lipase enzymes for detergent use include those produced by microorganisms of the Pseudomonas group, such as Pseudomonas stutzeri ATCC 19.154, as disclosed in British Patent 1,372,034. See also Upases in Japanese Patent Application 53,20487, laid open to public inspeαion on February 24, 1978. This lipase is available from Amano Pharmaceutical Co. Ltd., Nagoya, Japan, under the trade name Lipase P "Amano," hereinafter referred to as "Amano-P." Other commercial Upases include Amano-CES, Upases ex Chromobacter viscosum, e.g. Chromobacter viscosum var. lipolyticum NRRLB 3673, commercially available from Toyo Jozo Co., Tagata, Japan; and further Chromobacter viscosum Upases from U.S. Biochemical Corp., U.S.A. and Disoynth Co., The Netherlands, and Upases ex Pseudomonas gladioli. The LIPOLASE® enzyme derived from Humicola lanuginosa and commercially avaUable from Novo (see also EPO 341,947) is a preferred lipase for use herein. Peroxidase enzymes can be used in combination with oxygen sources, e.g., percarbonate, perborate, persulfate, hydrogen peroxide, etc. They are used for "solution bleaching," i.e. to prevent transfer of dyes or pigments removed from substrates during wash operations to other substrates in the wash solution. Peroxidase enzymes are known in the art, and include, for example, horseradish peroxidase, Ugninase, and haloperoxidase such as chloro- and bromo-peroxidase. Peroxidase-containing detergent compositions are disclosed, for example, in PCT International AppUcation WO 89/099813, published Oαober 19, 1989, by O. Kirk, assigned to Novo Industries A/S. A wide range of enzyme materials and means for their incorporation into synthetic detergent compositions are also disclosed in U.S. Patent 3,553,139, issued January 5, 1971 to McCarty et al. Enzymes are further disclosed in U.S. Patent 4,101,457, Place et al, issued July 18, 1978, and in U.S. Patent 4,507,219, Hughes, issued March 26, 1985. Enzyme materials useful for liquid detergent formulations, and their incorporation into such formulations, are disclosed in U.S. Patent 4,261,868, Hora et al, issued April 14, 1981. Enzymes for use in detergents can be stabilized by various techniques. Enzyme stabilization techniques are disclosed and exemplified in U.S. Patent 3,600,319, issued August 17, 1971 to Gedge, et al, and European Patent Application Publication No. 0 199 405, Application No. 86200586.5, published October 29, 1986, Venegas. Enzyme stabilization systems are also described, for example, in U.S. Patent 3,519,570. Other Ingredients - Usual detersive ingredients can include one or more other detersive adjunαs or other materials for assisting or enhancing cleaning performance, treatment of the substrate to be cleaned, or to modify the aesthetics of the detergent composition. Usual dαersive adjunαs of detergent compositions include the ingredients set forth in U.S. Pat. No. 3,936,537, Baskerville et al. Adjunαs which can also be included in detergent compositions employed in the present invention, in their conventional art-established levels for use (generally from 0% to about 20% of the detergent ingredients, preferably from about 0.5% to about 10%), include other active ingredients such as dispersant polymers from BASF Corp. or Rohm & Haas; color speckles, anti-tarnish and/or anti-corrosion agents, dyes, fUlers, optical bnghteners, germicides, aUcalinity sources, hydrotropes, anti-oxidants, enzyme stabilizing agents, perfumes, solubilizing agents, clay soU remolval/anti-redeposition agents, carriers, processing aids, pigments, solvents for liquid formulations, fabric softeners, static control agents, solid fillers for bar compositions, etc. Dye transfer inhibiting agents, including polyamine N-oxides such as polyvinylpyridine N-oxide can be used. Dye-transfer-inhibiting agents are further iUustrated by polyvinylpyrroUdone and copolymers of N-vinyl imidazole and N-vinyl pyrroUdone. If high sudsing is desired, suds boosters such as the C\Q-C\6 alkanolamides can be incorporated into the compositions, typically at 1%-10% levels. The C10-C14 monoethanol and diethanol amides iUustrate a typical class of such suds boosters. Use of such suds boosters with high sudsing adjunα surfaoants such as the amine oxides, betaines and sultaines noted above is also advantageous. If desired, soluble magnesium salts such as MgC , MgSO4, and the Uke, can be added at levels of, typicaUy, 0.1%-2%, to provide additional suds and to enhance grease removal performance. Various detersive ingredients employed in the present compositions optionally can be further stabilized by absorbing said ingredients onto a porous hydrophobic substrate, then coating said substrate with a hydrophobic coating. Preferably, the detersive ingredient is admixed with a surfaαant before being absorbed into the porous substrate. In use, the detersive ingredient is released from the substrate into the aqueous washing Uquor, where it performs its intended detersive function. To illustrate this technique in more detail, a porous hydrophobic siUca (trademark SLPERNAT® D10, Degussa) is admixed with a proteolytic enzyme solution containing 3%-5% of C13.15 ethoxylated alcohol (EO 7) nonionic surfaαant. Typically, the enzyme/surfaαant solution is 2.5 X the weight of siUca. The resulting powder is dispersed with stirring in silicone oil (various siUcone oU viscosities in the range of 500-12,500 can be used). The resulting siUcone oil dispersion is emulsified or otherwise added to the final detergent matrix. By this means, ingredients such as the aforementioned enzymes, bleaches, bleach aαivators, bleach catalysts, photoactivators, dyes, fluorescers, fabric conditioners and hydrolyzable surfaαants can be "proteαed" for use in detergents, including liquid laundry detergent compositions. Liquid or gel compositions can contain some water and other fluids as carriers. Low molecular weight primary or secondary alcohols exemplified by mαhanol, ethanol, propanol, and isopropanol are suitable. Monohydric alcohols are preferred for solubilizing surfaαant, but polyols such as those containing from 2 to about 6 carbon atoms and from 2 to about 6 hydroxy groups (e.g., 1,3-propanediol, ethylene glycol, glycerine, and 1,2-propanedioI) can also be used. The compositions may contain from 5% to 90%, typically 10% to 50% of such carriers. Certain bleaching compositions herein among the generally encompassed Uquid (easUy flowable or gel forms) and soUd (powder, granule or tablet) forms, especiaUy bleach additive compositions and hard surface cleaning compositions, may preferably be formulated such that the pH is acidic during storage and alkaline during use in aqueous cleaning operations, i.e., the wash water wiU have a pH in the range from about 7 to about 11.5. Laundry and automatic dishwashing produαs are typically at pH 7-12, preferably 9 to 11.5. Automatic dishwashing compositions, other than rinse aids which may be acidic, will typically have an aqueous solution pH greater than 7. Techniques for controlling pH at recommended usage levels include the use of buffers, alkalis, acids, pH-jump systems, dual compartment containers, etc., and are well known to those skilled in the art. The compositions are useful from about 5°C to the boil for a variety of cleaning and bleaching operations. Bleaching compositions in granular form typically limit water content, for example to less than about 7% free water, for best storage stability. Storage stabUity of bleach compositions can be further enhanced by limiting the content in the compositions of adventitious redox-aαive substances such as rust and other traces of transition metals in undesirable form. Certain bleaching compositions may moreover be limited in their total haUde ion content, or may have any particular halide, e.g., bromide, substantiaUy absent. Bleach stabilizers such as stannates can be added for improved stability and liquid formulations may be substantiaUy nonaqueous if desired. The following examples illustrate the MSBA's of the invention, intermediates for making same and bleaching compositions which can be prepared using the MSBA's, but are not intended to be limiting thereof. EXAMPLE I An MSBA, l,4-Di-(methyl-(6'-(Λ r l- V-Dimethylammonio)hexanoyl)caprolaαam) benzene dichloride, is prepared as follows: 2 (COO), 6-fiV.iV-Dimqhylamino^hexanoic acid (2) - To a 2000 mL three-necked round-bottomed flask equipped with an internal thermomαer and reflux condenser are added 6-aminocaproic acid (200.00 g, 1.53 mol), formaldehyde (357.61 g, 4.41 ol, 37 wt%), and formic acid (454.56 g, 8.69 mol, 88%). Once addition is complete, the mixture is heated to reflux for 3 h, then cooled to room temperature. Analysis by TLC (74:25: 1, propanol. water: formic acid, Rf=0.45) indicates the reaction is complete. To the crude mixture is added 158 mL of concentrated HCI (36-37%). The mixture is concentrated to dryness by rotary evaporation for 5 h to remove excess formaldehyde and formic acid. The hydrochloride is redissolved in 300 mL of water and neutralized with 132.5 g of 50 wt% NaOH solution to a pH of about 7.0. The mixture is concentrated by rotary evaporation with isopropanol to faciUtate drying. The produα is leached out from the soUds by triturating with dichioromethane. After drying the organic layer over MgSO4 and filtering, the product is isolated by concentrating the organic layer by rotary evaporation and drying under vacuum to give 2 as a white soUd, 251.86 g (>99% yield): mp 89-91 °C. 6-(yV.yV-Dimethylamino exanoyl chloride hydrochloride (3) - Into a 500 mL three-necked round-bottomed flask equipped with a reflux condenser, internal thermometer, mechanical stirrer, and argon inlet, is placed oxalyl chloride (398.67 g, 3.14 mol). Acid 2 (100 g, 0.63 mol) is added over 30 min while maintaining the reaαion temperature at 40 °C. As reaαion takes place, CO2 and CO are swept away from the mixture with argon. After addition is complete, the mixture is stirred for 2 h while the reaαion flask cools to room temperature. Excess oxalyl chloride is removed by rotary evaporation at 50 °C and then by Kugelrohr distiUation at 50 °C (0.1 mm Hg) for 2 h. Isolated is 3, 118.98 g (88.5%) as an oil that soUdifies on standing. ό-CiV.-V-Dimαhylamino^hexanoyl caprolaαam (4) - To a 1000 mL three- necked round-bottomed flask equipped with a reflux condenser, internal thermomαer, argon inlet, and mechanical stirrer, are added ε-caprolaαam (48.04 g, 0.42 mol), toluene (340 mL), and triαhylamine (189.00 g, 1.87 mol). The mixture is heated to reflux (ca. 101 °C) for 15 min. While at that temperature, acid chloride 3 (100.00 g, 0.47 mol) is added as a solid over 30 min. The reaαion is maintained at reflux for an additional 1.75 h before the heat is removed. At room temperature, the mixture is filtered and the salts washed with toluene. The dark filtrate is washed with saturated sodium bicarbonate solution (3 x 250 mL), water (100 mL), and dried over MgSO4. The mixture is filtered and concentrated by rotary evaporation at about 50°C (water aspirator) and then by Kugelrohr distUlation at 60 °C for 1 h to give 89.64 g (83%) of 4 as an oil. Now, 6-(/V,yV-Dimethylamino)hexanoyl caprolactam (4) (30.00 g, 0.118 mol) and acetonitrile (150 mL), are placed in a 500 mL three-necked round-bottomed flask fitted with a condenser and argon inlet. To the solution is added a,a'-dichloro- >- xylene (10.32 g, 0.059 mol) dissolved in 50 mL of acetonitrile. The mixture is heated to reflux for 2.5 h, cooled to room temperature, and concentrated by rotary evaporation at 50 °C. A brown semi-solid which remains is further concentrated at 60 °C (0.1 mm Hg) for 3 h. The soUd is triturated with acetonitrile and ether to remove impurities. The product, having diquaternary structure shown above, is isolated as a solid, 30.00 g (74%). EXAMPLE π An MSBA having the following structure: N^^^-Tetramethyl-jV^^^caprolaαam-N-carbony phenylmethyl)- 1,6- hexanediammonium dichloride. Preparation is as foUows. A single-neck, 500 mL round bottom flask equipped with magnetic stirring, a reflux condenser and argon line is charged with 75 mL acetonitrile, 6.48 g (37.6 mmol) N,_V,jVy^-tetramethyl-l,6-hexanedianιine > and 30.0 g (112.9 mmol) 4- chloromethylbenzoylcaprolaαam (see hereinafter). The mixture is heated at 50 °C for 2 hours, cooled and the solvent removed under reduced pressure. The remaining solid is slurried in acαone, filtered, washed with acαone and aUowed to air dry at ambient temperature to obtain an essentially quantitative yield of the MSBA as a powder. 4-Chloromαhylbenzoylcaprolaαam - A 3 -neck round bottom flask is fitted with mechanical stirring, reflux condenser, addition funnel, and gas inlet, and is charged with caprolaαam (0.5 mol), triethylamine (0.75 mol) and 75% of toluene (1.0 mol caprolactam/ 1.5 Uters toluene) under Argon. The solution is heated to reflux. 4- chloromethyl benzoyl acid chloride (0.5 mol), suspended in the remaining toluene, is added in a slow stream. The reaction is stirred under Argon at toluene reflux for 6 hours, cooled sUghtly and filtered. The collected soUd, triαhylamine hydrochloride, is discarded, and the filtrate is refrigerated to precipitate 4-chloromethylbenzoyl caprolaαam, which is colleαed by vacuum filtration, washed and dried. EXAMPLE III An MSBA having the following structure is prepared by reaαing one equivalent each of 6-(N,N-Dimethylamino)hexanoyl caprolactam (as prepared in example II) and 4-chloromethylbenzoyicaprolactam (as prepared in example II) together in acetonitrile. The reaαion is heated to 50 °C for 2 hours under argon, cooled to room temperature and the solvent is evaporated. Excess acetone is added to the flask with magnαic stirring to break apart the produα, and the mixture is heated to reflux briefly, then cooled to room temperature. The product is vacuum filtered, washed and dried to give the final produα, a soUd. EXAMPLE TV An MSBA having the foUowing structure is prepared as described in Example LU excepting that 6-(V,iV- Dimαhylamino)hexanoyl caprolactam is replaced with 6-(_V,τV- dimαhylamino)hexanoyl 2-mαhyl-2-imidazoline. Said 6-(yV. V-Dimethylamino ' )hexanoyl 2-methyl-2-imidazoline (4Y Dichloromethane (400 mL), 2-methyl-2-imidazoline (56.38 g, 0.637 mol), and triethylamine (283.51 g, 2.802 mol) are placed in a 2000 mL three-necked round bottomed flask equipped with a reflux condenser, internal thermometer, mechanical stirrer, addition funnel, and argon inlet. The solution is brought to reflux and 15 min later a solution of 6-(N,N- Dimethylamino)hexanoyl chloride hydrochloride (150 g, 0.700 mol), prepared as described in example II, dissolved in dichloromethane (300 mL) is added dropwise over 45 min. The mixture is refluxed for an additional 2 h before being cooled to room temperature. The salts are filtered and washed with methylene chloride. The combined filtrates are washed with 5% NaHCO3 solution (3 x 300 mL) and water (300 mL), After drying over MgSO4 and filtration, the organic layer is concentrated first by rotary evaporation at 50 °C and then by Kugelrohr distillation at 60-70 °C (0.2 mm Hg) to give 95.20 g (66%) of an oil which solidifies on standing. EXAMPLE V An MSBA having the following structure: is prepared by reaαing five mole equivalents of N,N,N',N'-tetramαhyl-l,6- hexanediamine with one mole equivalent of 4-chloromethylbenzoylcaprolaαam (as prepared in Example II) in acetonitrile at 50 °C for 2 hours and thereafter removing excess N,N,N, -tetramethyl-l,6-hexanediamine under reduced pressure or by trituration. The residue is taken up in acαonitrile, heated to 50 °C and charged with one mole equivalent of benzyl chloride after which heating is continued another 2 hours before the reaction mixture is filtered. The coUeαed solids, washed first with acαone, then with hexane, are dried to obtain the desired MSBA. EXAMPLE VI Granular laundry detergents are exemplified by the following formulations.
