All documents cited are in relevant part, incorporated herein by reference. DETAILED DESCRIPTION OF THE INVENTION The present invention relates to laundry detergent compositions which comprise a fabric enhancement system. The laundry detergent compositions comprise from about 0.01%, preferably from about 0.1%, more preferably from 0.25%, most preferably from about 0.5% to about 20%, preferably to about 10%, more preferably to about 5% by weight, of a fabric enhancement system. Said fabric enhancement system is comprised of one or more modified polyamine compounds. The fabric care and/or fabric enhancement compositions may take any form, for example, solids (i.e., powders, granules, extrudates), gels, thixotropic liquids, liquids (i.e., dispersions, isotropic solutions), preferably the rinse-added fabric conditioning compositions take the form of liquid dispersions or isotropic liquids. For the purposes of the present invention the terms "fabric enhancement" and "fabric care" are used interchangeable throughout the present specification and stand equally well for one another. Fabric enhancement/fabric care is achieved when the properties ter alia color, fiber integrity of the garment are conserved (that is no further damage is done during the laundry process) or the damaging process is reversed and the fabric appears more like its original form. Fabric Enhancement System The fabric enhancement system of the present invention is comprised of one or more modified polyamines according to the present invention. The modified polyamines of the present invention which comprise the fabric enhancement system may be formulated as an admixture wherein a proportional amount of two or more compounds are combined to make up the fabric enhancement system. Alternatively, the formulator may adjust the reaction conditions which form the modified polyamines of the present invention in order to create an admixture of suitable ingredients inter alia an admixture of polyamine fragments and/or partially crosslinked modified polyamines. Whether a formulated admixture or a product by process is used, or a mixture of both, the compounds which comprise the fabric enhancement compositions of the present invention have the formula: i) (PA) W (T)„ ii) (PA) W (L)-; iii) [(PA) w (T)J y [L] z ; wherein PA is a grafted or non-grafted, modified or unmodified polyamine backbone unit, T is an amide-forming polycarboxylic acid crosslinking unit, and L is a non-amide forming crosslinking unit. For compounds of type (i) and (iii) the relative amounts of PA units and T units which are present are such that the molar ratio of PA units to T units is from 0.8 : 1 to 1.5 : 1. For compounds of type (ii) the relative amounts of PA units and L units which are present are such that the (PA) W (L) Z comprises from about 0.05, preferably from about 0.3 to 2 parts by weight of said L units. Therefore, 1 part of a grafted or non-grafted, modified or unmodified polyamine backbone unit may be combined with from about 0.05, preferably from about 0.3 parts by weight of an L unit to about 2 parts by weight of an L unit to form a suitable modified polyamine compound. Likewise, for compounds of type (iii), crosslinked polyamines having the formula (PA) W (T) X may be combined with from about 0.05, preferably from about 0.3 parts by weight of an L unit to about 2 parts by weight of an L unit to form a suitable modified polyamine compound having the formula [(PA) W (T) X ] V [L] Z . Polyamine Backbone (PA units) The modified polyamine compounds of the present invention comprise a Polyamine Backbone, PA unit, which can be optionally, but preferably grafted. The following are non- limiting examples of suitable PA units according to the present invention. Polyalkyleneimine A preferred PA unit according to the present invention are polyalkyleneimines and polyalkyleneamines having the general formula: H B I I [H 2 N-R] w [N-R] x [N-R] y NH 2 wherein R is C 2 -C 12 linear alkylene, C 3 -C 12 branched alkylene, and mixtures thereof; B representing a continuation of the chain structure by branching. The indices w, x, and y have various values depending upon such factors as molecular weight and relative degree of branching. The polyalkyleneimines and polyalkyleneamines which comprise PA units of the present invention are divided into three categories based upon relative molecular weight. The terms polyalkyleneimine and polyalkyleneamine are used interchangeably throughout the present specification and are taken to mean polyamines having the general formula indicated above regardless of method of preparation. Low Molecular Weight Polyalkyleneimines For low molecular weight polyalkyleneimines having the formula: H B I [H 2 N- R] w [N- R] x [N- R] y NH 2 R is C 2 -C 12 linear alkylene, C 3 -C 12 branched alkylene, and mixtures thereof; preferably R is ethylene, 1,3-propylene, and 1 ,6-hexylene, more preferred is ethylene. The indices w, x, and y are such that the molecular weight of said polyamines does not exceed about 600 daltons. For example, for an entirely linear polyethyleneimine having a molecular weight of about 600 daltons, the index w = 1, x = 13, and y = 0. For an entirely branched polyethyleneimine having a molecular weight of approximately 600 daltons, w = 8, x = 0 and y =7. (This combination of indices results in a material having an average molecular weight of about 646 daltons, which, for the purposes of the present invention is a low molecular weight polyalkyleneimine.) The index w typically has the value of y + 1. The simplest of the low molecular weight polyamines of this type is ethylene diamine which may be present up to about 10% by weight of the PA unit mixture. Non-limiting examples of low molecular weight polyalkyleneimine PA units include diethylene triamine, triethylene tetramine, tetraethylene pentamine, dipropylene triamine, tripropylene tetramine, and dihexamethylene triamine. PA units may be used as crude products or mixtures, and if desired by the formulator, these PA units may be used in the presence of small amounts of diamines as described herein above, wherein the amount of diamines, inter alia, ethylene diamine, hexamethylene diamine may be present up to about 10% by weight, of the PA unit mixture. Medium Range Molecular Weight Polyalkyleneimines For medium range molecular weight polyalkyleneimines having the formula: H B I I [H 2 N- R] w [N- R] x [N- R] y NH 2 R is C 2 -C 4 linear alkylene, C 3 -C 4 branched alkylene, and mixtures thereof; preferably R is ethylene, 1,3-propylene, and mixtures thereof, more preferred is ethylene wherein said polyamines are polyethylene-mines (PEI's). The indices w, x, and y are such that the molecular weight of said polyamines is from about 600 daltons to about 50,000 daltons. The indices w, x, and y will indicate not only the molecular weight of the polyalkyleneimines but also the degree of branching present in the PA unit backbone. High Molecular Weight Polyalkyleneimines For high molecular weight polyalkyleneimines having the formula: H B I I [H 2 N- R] w [N- R] x [N- R] y NH 2 R is C 2 -C 3 linear alkylene, preferably R is ethylene. The indices w, x, and y are such that the molecular weight of said polyamines is from about 50,000 daltons to about 1,000,000 (1 million) daltons. The indices w, x, and y will indicate not only the molecular weight of the polyalkyleneimines but also the degree of branching present in the PA unit backbone. Co-polymeric Polyamines Another example of a preferred PA unit according to the present invention are the polyvinyl amine homo-polymers or co-polymers having the formula: wherein V is a co-monomer, non-limiting examples of which include vinyl amides, vinyl pyrrolidone, vinyl imidazole, vinyl esters, vinyl alcohols, and mixtures thereof, all of which can be taken together or in combination with polyvinyl amine to form suitable co-polymerization products suitable for use in the fabric enhancement systems of the present invention. The indices m and n are such that the copolymers comprise at least 10%, more preferably at least about 30% of units derived from vinyl amine and wherein further the molecular weight of said copolymers if from about 500 daltons, preferably from about 5,000 daltons to about 50,000 daltons, preferably to about 20,000 daltons. Polyamine Backbone Modifications Optionally but preferably the PA units of the present invention are modified either before or after reaction with a T unit or L unit crosslinking agent. The two preferred types of modifications are grafting and capping. Preferably the PA units of the present invention are grafted, that is the PA unit is further reacted with a reagent which elongates said PA unit chain, preferably by reaction of the nitrogens of the PA backbone unit with one or more equivalents of aziridine (ethyleneimine), caprolactam, and mixtures thereof. Grafting units, in contrast to the "capping" units described herein below, can further react on themselves to provide PA unit chain propagation. An example of a preferred grafted PA unit of the present invention has the formula: G B I I [G 2 N-R] W [N-R] X [N-R] y NG 2 wherein R, B, w, x, and y are the same as defined herein above and G is hydrogen or an extension of the PA unit backbone by grafting. Non-limiting examples of preferred grafting agents are aziridine (ethyleneimine), caprolactam, and mixtures thereof. A preferred grafting agent is aziridine wherein the backbone is extended by units having the formula: B' I - [CH 2 CH 2 NH] p [CH 2 CH 2 N] q CH 2 CH 2 NH 2 wherein B' is a continuation by branching wherein the graft does not exceed about 8 units, preferably -CH 2 CH 2 NH 2 and the value of the indices p + q have the value from 0, preferably from about 1 , more preferably from about 2 to about 7, preferably to about 5. Another preferred grafting unit is caprolactam. The PA units of the present invention can be grafted pπor to or after crosslinking with one or more T units described herein below, preferably the grafting is accomplished after crosslinking with said T unit. This allows the formulator to take advantage of the differential reactivity between the primary and secondary ammo units of the PA unit backbone thereby allowing the formulator to controllably link said PA units and to also control the amount of subsequent branching which results from the grafting step. Another optional but preferred PA unit modification is the presence of "capping" units. For example, a PA unit is reacted with an amount of a monocarboxyhc acid, non-limiting examples of which are C,-C 22 linear or branched alkyl, preferably C 10 -C 18 linear alkyl inter aha lauπc acid, myπstic acid The amount of capping unit which is reacted with the PA unit is an amount which is sufficient to achieve the desired properties of the formula. However, the amount of capping unit used is not sufficient to abate any further crosslinking or grafting which the formulator may choose to perform. Crosslinking Units Amide-forming T Crosslinking Units T crosslinking units are preferably carbonyl compπsmg polyamido forming units. The T units are taken together with PA units to form crosslmked modified polyamine compounds having the formula (PA) W (T) X or [(PA) w (T) x ] y [L] z . A preferred embodiment of the present invention includes crosslmked PA units wherein a T unit provides crosslinking between two or more PA units to form a (PA) ft (T) λ polyamido crosslmked section. A preferred crosslinking T unit has the general formula: O O — C 1 1 — (R 2 2 ) — (R 1 1 ) k -(R 2 2 ) -C l ! — wherein R 1 is methylene, phenylene, and mixtures thereof; preferably methylene The index k has the value from 2 to about 8, preferably to about 4. Preferred values of k are 2, 3, and 4 R 2 is - NH- thereby forming a urethane amide linkage when said R 2 comprising T units react with the backbone nitrogens of the PA units. The value of the index j is independently 0 or 1 The presence of R 2 units can result, for example, from the use of diisocyanates as crosslinking agents. Non-limiting examples of dibasic acids which are used as a source for T units in the above formula include succinic acid, maleic acid, adipic acid, glutaric acid, suberic acid, sebacic acid, and terephthalic acid. However, the formulator is not limited to crosslinking T units deriving from dibasic acids, for example, tribasic crosslinking T units, wter alia, citrate, may be used to link the PA units of the present invention. Examples of (PA) W (T) X compounds according to the present invention are obtained by condensation of dicarboxylic acids inter alia succinic acid, maleic acid, adipic acid, terephthalic acid, with polyalkylene polyamines inter alia diethylenetriamine, triethylenetetramine, dipropylenetriamine, tripropylenetetramine wherein the ratio of the dicarboxylic acid to polyalkyleneamine is from 1 :0.8 to 1 : 1.5 moles, preferably a ratio of from 1 :0.9 to 1 : 1.2 moles wherein the resulting crosslinked material has a viscosity in a 50% by weight, aqueous solution of more than 100 centipoise at 25 °C. Non-amide Forming L Crosslinking Units Another preferred embodiment of the polyamines of the present invention are (P A) W (T) X units which are further crosslinked by L units to form polyamido amines having the formula [(PA) w (T) x ] y [L] z or are reacted with PA units to form non-amide polyamines having the formula (PA) W (L) Z . The L units of the present invention are any unit which suitably crosslinks PA units or (PA) W (T) X units. Preferred L linking units comprise units which are derived from the use of epihalohydrins, preferably epichlorohydrin, as a crosslinking agent. The epihalohydrins can be used directly with the PA units or suitably combined with other crosslinking adjuncts non- limiting examples of which include alkyleneglycols, and polyalkylene polyglycols inter alia ethylene glycol, diethylene glycol, polyethylene glycol, propylene glycol, dipropylene glycol, polypropylene glycol, butylene glycol, hexanediol-l,6-glycerol, oligoglycerol, pentaerythrites, polyols which are obtained by the reduction of carbohydrates (sorbitol, mannitol), monosaccharides, disaccharides, oligosaccharides, polysaccharides, polyvinyl alcohols, and mixtures thereof. For example, a suitable L unit is a dodecylene unit having the formula: (CH 2 ) 12 wherein an equivalent of 1,12-dichlorododecane is reacted, for example, with a suitable amount of a PA unit to produce a polyamine which is crosslinked via dodecylene units. For the purposes of the present invention, L crosslinking units which comprise only carbon and hydrogen are considered to be "hydrocarbyl" L units. Preferred hydrocarbyl units are polyalkylene units have the formula: (CH 2 ) n wherein n is from 1 to about 50. Hydrocarbyl L units may be derived from hydrocarbons having two units which are capable of reacting with the nitrogen of the PA units. Non-limiting examples of precursors which result in the formation of hydrocarbyl L units include 1,6-dibromohexane, 1,8- ditosyloctane, and 1,14-dichlorotetradecane. Further examples of preferred non-amide forming crosslinking L units are the units which derive from crosslinking units wherein epihalohydrin is used as the connecting unit. For example, 1,12-dihydroxydodecane is reacted with epichlorohydrin to form the bis-epoxide non- amide forming L unit precursor having the formula: r> CH 2 0— (CH 2 ) 12 — OCH 2 <1 & O which when reacted with one or more PA units or (PA) W (T) units results in an L crosslinking unit having the formula: CH 2 — CH — CH 2 0 — (CH 2 ) , 2 — OCH 2 — CH — CH 2 — OH OH however, it is not necessary to pre-form and isolate the bis-epoxide, instead the crosslinking unit precursor may be formed in situ by reaction of 1,12-dihydroxydodecane or other suitable precursor unit with epihalohydrin in the presence of grafted or ungrafted PA units or (PA) W (T) X units. Other crosslinking L units which utilize one or more epihalohydrin connecting units include polyalkyleneoxy L units having the formula: CH 2 — CH— CH 2 — 0(R 1 0) x (R 2 0) y — CH 2 — CH— CH 2 — OH OH wherein R 1 is ethylene, R 2 is 1 ,2-propylene, x is from 0 to 100 and y is from 0 to 100. Another preferred unit which can comprise an L unit and which can be suitably combined with epihalohydrin connecting units include polyhydroxy units having the formula: OH I CH 2 — CH— CH 2 — 0(CH 2 ) t (CH) u O— CH 2 — CH— CH 2 — OH OH wherein the index t is from at least 2 to about 20 and the index u is from 1 to about 6. The formulator may also combine units to form hybrid L crosslinking units, for example, units having the formula: OH I CH 2 — CH-CH 2 — fθ(CH 2 ) t (CH) u O 0(R 1 0) x (R 2 0) y - CH 2 -CH— CH 2 - OH OH wherein the indexes w and y are each independently from 1 to 50, z is units are present in a sufficient to suitably connect the polyhydroxy units and the polyalkyleneoxy units into the backbone without the formation of ether linkages. The following is an example of an L linking group which comprises both a polyalkyleneoxy and a polyhydroxy unit. OH CH 2 OH CH 2 CHCH 2 -OCH 2 CHCHCHCHO— CH 2 CHCH 2 — 0(CH 2 CH 2 0) 4 - -CH 2 CHCH 2 — OH OH OH OH A further example of a preferred crosslinking L units are units which comprises at least two aziridine groups as connecting groups, for example an L unit having the formula: which can be used to link two (PA) W units, two (PA) W (T) X units, or mixtures thereof. The polyamines of the present invention may have varying final compositions, for example, (PA) W (T) X , [(PA) w (T) x ] y [L] z , [(PA)] W [L] Z , and mixtures thereof, wherein each PA unit may be grafted or ungrafted. The indices w and x have values such that the ratio of w to x is from 0.8 : 1 to 1.5 : 1 ; y and z have values such that said polyamido compound comprises from about 0.3 to 2 parts by weight of said L unit. In the cases wherein no crosslinking takes place the indices w and y will be equal to 1 and x and z will be equal to 0. In the case wherein no crosslinking occurs using L units, the index y is equal to 1 and z is equal to 0. In the case wherein no crosslinking occurs using T units, the indices w and y are equal to 1 and x is equal to 0. An preferred embodiment of the present invention which comprises PA units, T units, and L units includes the reaction product of: a) 1 part by weight, of a polyamine obtained by condensation of 1 mole of a dicarboxylic acid with a polyalkylene polyamine (i.e., diethylenetriamine) to the extent wherein at least about 10% of the -NH backbone hydrogens are unmodified by reaction with said dicarboxylic acid, then optionally reacting the obtained polyamine condensation product with up to 8 ethyleneimine units (i.e., grafting of the backbone using aziridine) per basic nitrogen atom; and b) further reacting the product obtained in (a) with from 0.3 to 2 parts by weight, of an L units, inter alia the reaction product of a polyalkylene oxide having from 8 to 100 alkylene oxide units with epichlorohydrin at a temperature of form about 20 °C to about 100 °C.

The laundry detergent compositions of the present invention can also comprise from about 0.001% to about 100% of one or more (preferably a mixture of two or more) mid-chain branched surfactants, preferably mid-chain branched alkyl alkoxy alcohols having the formula: R R 1 R 2 I CH 3 CH 2 (CH 2 ) w CH(CH 2 )^CH(CH 2 ) y CH(CH 2 ) 2 (EO/PO) m OH mid-chain branched alkyl sulfates having the formula: R R 1 R 2 I I I CH 3 CH 2 (CH 2 ) w CH(CH 2 ) x CH(CH 2 ) y CH(CH 2 ) 2 OS0 3 M and mid-chain branched alkyl alkoxy sulfates having the formula: R R 1 R 2 I I I CH 3 CH 2 (CH 2 ) w CH(CH 2 )^CH(CH 2 ) y CH(CH 2 ) z (EO/PO) m OS0 3 M wherein the total number of carbon atoms in the branched primary alkyl moiety of these formulae (including the R, R 1 , and R^ branching, but not including the carbon atoms which comprise any EO/PO alkoxy moiety) is from 14 to 20, and wherein further for this surfactant mixture the average total number of carbon atoms in the branched primary alkyl moieties having the above formula is within the range of greater than 14.5 to about 17.5 (preferably from about 15 to about 17); R, R 1 , and R^ are each independently selected from hydrogen, Ci -C3 alkyl, and mixtures thereof, preferably methyl; provided R, R', and R^ are not all hydrogen and, when z is 1, at least R or R! is not hydrogen. M is a water soluble cation and may comprises more than one type of cation, for example, a mixture of sodium and potassium. The index w is an integer from 0 to 13; x is an integer from 0 to 13; y is an integer from 0 to 13; z is an integer of at least 1; provided w + x + y + z is from 8 to 14. EO and PO represent ethyleneoxy units and propyleneoxy units having the formula: CH 3 CH 3 I I CHCH 2 0 or CH 2 CHO respectively, however, other alkoxy units inter alia 1,3 -propyleneoxy, butoxy, and mixtures thereof are suitable as alkoxy units appended to the mid-chain branched alkyl moieties. The mid-chain branched surfactants are preferably mixtures which comprise a surfactant system. Therefore, when the surfactant system comprises an alkoxylated surfactant, the index m indicates the average degree of alkoxylation within the mixture of surfactants. As such, the index m is at least about 0.01, preferably within the range of from about 0.1, more preferably from about 0.5, most preferably from about 1 to about 30, preferably to about 10, more preferably to about 5. When considering a mid-chain branched surfactant system which comprises only alkoxylated surfactants, the value of the index m represents a distribution of the average degree of alkoxylation corresponding to m, or it may be a single specific chain with alkoxylation (e.g., ethoxylation and/or propoxylation) of exactly the number of units corresponding to m.

The surfactant systems of the present invention which comprise mid-chain branched surfactants are preferably formulated in two embodiments. A first preferred embodiment comprises mid-chain branched surfactants which are formed from a feedstock which comprises 25% or less of mid-chain branched alkyl units. Therefore, prior to admixture with any other conventional surfactants, the mid-chain branched surfactant component will comprise 25% or less of surfactant molecules which are non-linear surfactants. A second preferred embodiment comprises mid-chain branched surfactants which are formed from a feedstock which comprises from about 25% to about 70% of mid-chain branched alkyl units. Therefore, prior to admixture with any other conventional surfactants, the mid-chain branched surfactant component will comprise from about 25% to about 70% surfactant molecules which are non-linear surfactants. The surfactant systems of the laundry detergent compositions of the present invention can also comprise from about 0.001%, preferably from about 1%, more preferably from about 5%, most preferably from about 10% to about 100%, preferably to about 60%, more preferably to about 30% by weight, of the surfactant system, of one or more (preferably a mixture of two or more) mid-chain branched alkyl arylsulfonate surfactants, preferably surfactants wherein the aryl unit is a benzene ring having the formula: wherein L is an acyclic hydrocarbyl moiety comprising from 6 to 18 carbon atoms; R 1 , R 2 , and R 3 are each independently hydrogen or C r C 3 alkyl, provided R 1 and R 2 are not attached at the terminus of the L unit; M is a water soluble cation having charge q wherein a and b are taken together to satisfy charge neutrality. ADJUNCT INGREDIENTS The following are non-limiting examples of adjunct ingredients useful in the laundry compositions of the present invention, said adjunct ingredients include builders, optical brighteners, soil release polymers, dye transfer agents, dispersents, enzymes, suds suppressers, dyes, perfumes, colorants, filler salts, hydrotropes, photoactivators, fluorescers, fabric conditioners, hydrolyzable surfactants, preservatives, anti-oxidants, chelants, stabilizers, anti- shrinkage agents, anti-wrinkle agents, germicides, fungicides, anti corrosion agents, and mixtures thereof. Builders - The laundry detergent compositions of the present invention preferably comprise one or more detergent builders or builder systems. When present, the compositions will typically comprise at least about 1% builder, preferably from about 5%, more preferably from about 10% to about 80%, preferably to about 50%, more preferably to about 30% by weight, of detergent builder. 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. Formulations typically comprise from about 5% to about 50%, more typically about 5% to about 30%, by weight, of detergent builder. Granular formulations 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 meant to be 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. Examples of silicate builders are the alkali metal silicates, particularly those having a Si0 2 :Na 2 0 ratio in the range 1.6:1 to 3.2:1 and layered silicates, such as the layered sodium silicates described in U.S. 4,664,839 Rieck, issued May 12, 1987. NaSKS-6 is the trademark for 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 has the delta-Na 2 Siθ5 morphology form of layered silicate. It 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 0 2x +ι -yH 2 0 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 alpha, beta and gamma forms. As noted above, the delta-Na 2 Siθ5 (NaSKS-6 form) is most preferred for use herein. 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. 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. 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 (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. 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. 3,985,669, Krummel 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 especially preferred embodiment, the crystalline aluminosilicate ion exchange material has the formula: Na 12 [(A10 2 ) 12 (Si0 2 ) 12 ]-xH 2 0 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. 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, "poly- carboxylate" 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. 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 polycarboxy- lates, including oxydisuccinate, as disclosed in U.S. 3,128,287 Berg, issued April 7, 1964, and U.S. 3,635,830 Lamberti et al., issued January 18, 1972. See also "TMS/TDS" builders of U.S. 4,663,071 Bush et al., issued May 5, 1987. Suitable ether polycarboxylates also include cyclic compounds, particularly alicyclic compounds, such as those described in 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; and U.S. 4,102,903 Crutchfield et al., issued July 25, 1978. 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 ethylenediamine tetraacetic acid and nitrilotriacetic acid, as well as polycarboxylates such as mellitic acid, succinic acid, oxy- disuccinic 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 liquid detergent formulations due to their availability from renewable resources and their biodegradability. Citrates can also be used in granular compositions, especially 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-dicar- boxy-4-oxa-l,6-hexanedioates and the related compounds disclosed in U.S. 4,566,984, Bush, issued January 28, 1986. Useful succinic acid builders include the C5-C 2 o alkyl and alkenyl succinic acids and salts thereof. A particularly preferred compound of this type is do- decenylsuccinic acid. Specific examples of succinate builders include: laurylsuccinate, myristylsuccinate, palmitylsuccinate, 2-dodecenylsuccinate (preferred), 2-pentadecenylsucci- nate, 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. 4,144,226, Crutchfield et al., issued March 13, 1979 and in U.S. 3,308,067, Diehl, issued March 7, 1967. See also Diehl U.S. Patent 3,723,322. Fatty acids, e.g., Ci 2 -Cι g 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 activity. 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 tripolyphosphates, sodium pyrophosphate and sodium orthophosphate can be used. Phosphonate builders such as ethane- 1 -hydroxy- 1,1-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. Dispersants A description of other suitable polyalkyleneimine dispersants which may be optionally combined with the bleach stable dispersants of the present invention can be found in U.S. 4,597,898 Vander Meer, issued July 1, 1986; European Patent Application 111,965 Oh and Gosselink, published June 27, 1984; European Patent Application 111,984 Gosselink, published June 27, 1984; European Patent Application 112,592 Gosselink, published July 4, 1984; U.S. 4,548,744 Connor, issued October 22, 1985; and U.S. 5,565,145 Watson et al., issued October 15, 1996; all of which are included herein by reference. However, any suitable clay/soil dispersant or anti-redepostion agent can be used in the laundry compositions of the present invention. In addition, polymeric dispersing agents which include polymeric polycarboxylates and polyethylene glycols, are suitable for use in the present invention. Polymeric polycarboxylate materials can be prepared by polymerizing or copolymerizing suitable unsaturated monomers, preferably in their acid form. Unsaturated monomeric acids that can be polymerized to form suitable polymeric polycarboxylates include acrylic acid, maleic acid (or maleic anhydride), fumaric acid, itaconic acid, aconitic acid, mesaconic acid, citraconic acid and methylenemalonic acid. The presence in the polymeric polycarboxylates herein or monomeric segments, containing no carboxylate radicals such as vinylmethyl ether, styrene, ethylene, etc. is suitable provided that such segments do not constitute more than about 40% by weight. Particularly suitable polymeric polycarboxylates can be derived from acrylic acid. Such acrylic acid-based polymers which are useful herein are the water-soluble salts of polymerized acrylic acid. The average molecular weight of such polymers in the acid form preferably ranges from about 2,000 to 10,000, more preferably from about 4,000 to 7,000 and most preferably from about 4,000 to 5,000. Water-soluble salts of such acrylic acid polymers can include, for example, the alkali metal, ammonium and substituted ammonium salts. Soluble polymers of this type are known materials. Use of polyacrylates of this type in detergent compositions has been disclosed, for example, in Diehl, U.S. Patent 3,308,067, issued march 7, 1967. Acrylic/maleic-based copolymers may also be used as a preferred component of the dispersing/anti-redeposition agent. Such materials include the water-soluble salts of copolymers of acrylic acid and maleic acid. The average molecular weight of such copolymers in the acid form preferably ranges from about 2,000, preferably from about 5,000, more preferably from about 7,000 to 100,000, more preferably to 75,000, most preferably to 65,000. The ratio of acrylate to maleate segments in such copolymers will generally range from about 30:1 to about 1:1, more preferably from about 10:1 to 2: 1. Water-soluble salts of such acrylic acid/maleic acid copolymers can include, for example, the alkali metal, ammonium and substituted ammonium salts. Soluble acrylate/maleate copolymers of this type are known materials which are described in European Patent Application No. 66915, published December 15, 1982, as well as in EP 193,360, published September 3, 1986, which also describes such polymers comprising hydroxypropylacrylate. Still other useful dispersing agents include the maleic/acrylic/vinyl alcohol terpolymers. Such materials are also disclosed in EP 193,360, including, for example, the 45/45/10 terpolymer of acrylic/maleic/vinyl alcohol. Another polymeric material 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. Soil Release Agents The compositions according to the present invention may optionally comprise one or more soil release agents. If utilized, soil release agents will generally comprise from about O.O /o, preferably from about 0.1%, more preferably from about 0.2% to about 10%, preferably to about 5%, more preferably to about 3% by weight, of the composition. Polymeric soil release agents are characterized by having both hydrophilic segments, to hydrophilize the surface of hydrophobic fibers, such as polyester and nylon, and hydrophobic segments, to deposit upon hydrophobic fibers and remain adhered thereto through completion of the laundry cycle and, thus, serve as an anchor for the hydrophilic segments. This can enable stains occuring subsequent to treatment with the soil release agent to be more easily cleaned in later washing procedures. The following, all included herein by reference, describe soil release polymers suitable for use in the present invention.

Further suitable soil release agents are described in U.S. 4,201,824 Voilland et al; U.S. 4,240,918 Lagasse et al; U.S. 4,525,524 Tung et al; U.S. 4,579,681 Ruppert et al; U.S. 4,220,918; U.S. 4,787,989; EP 279,134 A, 1988 to Rhone-Poulenc Chemie; EP 457,205 A to BASF (1991); and DE 2,335,044 to Unilever N.V., 1974; all incorporated herein by reference. As a non-limiting example, granular compositions are generally made by combining base granule ingredients, e.g., surfactants, builders, water, etc., as a slurry, and spray drying the resulting slurry to a low level of residual moisture (5-12%). The remaining dry ingredients, e.g., granules of the polyalkyleneimine dispersant, can be admixed in granular powder form with the spray dried granules in a rotary mixing drum. The liquid ingredients, e.g., solutions of the polyalkyleneimine dispersant, enzymes, binders and perfumes, can be sprayed onto the resulting granules to form the finished detergent composition. Granular compositions according to the present invention can also be in "compact form", i.e. they may have a relatively higher density than conventional granular detergents, i.e. from 550 to 950 g/1. In such case, the granular detergent compositions according to the present invention will contain a lower amount of "inorganic filler salt", compared to conventional granular detergents; typical filler salts are alkaline earth metal salts of sulphates and chlorides, typically sodium sulphate; "compact" detergents typically comprise not more than 10% filler salt. Liquid detergent compositions can be prepared by admixing the essential and optional ingredients thereof in any desired order to provide compositions containing components in the requisite concentrations. Liquid compositions according to the present invention can also be in "compact form", in such case, the liquid detergent compositions according to the present invention will contain a lower amount of water, compared to conventional liquid detergents. Addition of the polyalkyleneimine dispersant to liquid detergent or other aqueous compositions of this invention may be accomplished by simply mixing into the liquid solutions the polyalkyleneimine dispersant. The compositions of the present invention can be suitably prepared by any process chosen by the formulator, non-limiting examples of which are described in U.S. 5,691,297 Nassano et al., issued November 11, 1997; U.S. 5,574,005 Welch et al., issued November 12, 1996; U.S. 5,569,645 Dinniwell et al., issued October 29, 1996; U.S. 5,565,422 Del Greco et al., issued October 15, 1996; U.S. 5,516,448 Capeci et al., issued May 14, 1996; U.S. 5,489,392 Capeci et al., issued February 6, 1996; U.S. 5,486,303 Capeci et al., issued January 23, 1996 all of which are incorporated herein by reference.
