Description: DETERGENT COMPOSITIONS COMPRISING POLYMERIC SUDS ENHANCERS AND THEIR USE FIELD OF THE INVENTION The present invention relates to polymers, mixtures thereof suitable for use as suds volume and suds duration enhancers in detergent compositions useful for hand washing of dishware and cookware. The present invention also relates to polymers having sufficient cationic charge at a pH of from about 4 to about 12 to be effective as suds volume and suds duration enhancers. BACKGROUND OF THE INVENTION Liquid detergent compositions which are suitable for hand dishwashing must satisfy several criteria in order to be effective. These compositions must be effective in cutting grease and greasy food material and once removed, must keep the greasy material from re-depositing on the dishware. The presence of suds in a hand dishwashing operation has long been used as a signal that the detergent continues to be effective. However, depending upon the circumstances, the presence of suds or the lack thereof, has no bearing upon the efficacy of liquid detergents. Therefore, the consumer has come to rely upon a somewhat erroneous signal, the lack or absence of soap suds, to indicate the need for additional detergent. In many instances the consumer is adding an additional amount of detergent far in excess of the amount necessary to thoroughly clean the dishes. This wasteful use of detergent is especially true in hand dishwashing since the soiled cooking articles are usually cleaned in a "washing difficulty" queue, for example, glasses and cups, which usually do not contact greasy food, are washed first, followed by plates and flatware, and finally pots and pans which contain the most residual food material and are usually, therefore, the "greasiest". The lack of suds in the dishwater when pots and pans are usually cleaned, together with the visual inspection of the amount of residual food material on the cookware surface, typically compels the consumer to add additional detergent when a sufficient amount still remains in solution to effectively remove the soil and grease from the dishware or cookware surface. However, effective grease cutting materials do not necessarily produce a substantial amount of corresponding suds. Accordingly, there remains a need in the art for liquid dishwashing detergents useful for hand washing dishware which have an enduring suds level while maintaining effective grease cutting properties. The need exists for a composition which can maintain a high level of suds as long as the dishwashing composition is effective. Indeed, there is a long felt need to provide a hand dishwashing composition which can be used efficiently by the consumer such that the consumer uses only the necessary amount of detergent to fully accomplish the cleaning task. SUMMARY OF THE INVENTION The present invention meets the aforementioned needs in that it has been surprisingly discovered that certain polymers serve as suds duration and suds volume extenders. The effective polymers of the present invention provide both increased suds volume and suds duration when formulated in a liquid detergent having a pH range of from about 4 to about 12 when measured as a 10% aqueous solution. A first aspect of the present invention relates to detergent compositions suitable for use in hand dishwashing, said composition comprising: a) an effective amount of a polymeric suds stabilizer comprising at least one monomeric unit of the formula: wherein each of R 1 , R 2 and R 3 are independently selected from the group consisting of hydrogen, C, to C 6 alkyl, and mixtures thereof; L is selected from the group consisting of a bond, O, NR 6 , SR 7 R 8 and mixtures thereof, wherein R 6 is selected from the group consisting of hydrogen, C, to C 8 alkyl and mixtures thereof; each of R 7 and R 8 are independently hydrogen, O, C, to C 8 alkyl and mixtures thereof, or SR 7 R 8 form a heterocyclic ring containing from 4 to 7 carbon atoms, optionally containing additional hetero atoms and optionally substituted; Z is selected from the group consisting of: -(CH 2 )-, (CH 2 -CH=CH)-, -(CH 2 -CHOH)- , (CH 2 -CHNR 6 )-, -(CH 2 -CHR ,4 -O)- and mixtures thereof; wherein R 14 is selected from the group consisting of hydrogen, C, to C 6 alkyl and mixtures thereof; z is an integer selected from about 0 to about 12; A is NR 4 R 5 , wherein each of R 4 and R 5 are independently selected from the group consisting of hydrogen, Cj-Cg linear or branched alkyl, alkyleneoxy having the formula: wherein T ® is C2-C4 linear or branched alkylene, and mixtures thereof; R*** *** is hydrogen, C1-C4 alkyl, and mixtures thereof; y is from 1 to about 10;, or NR 4 R 5 form an heterocyclic ring containing from 4 to 7 carbon atoms, optionally containing additional hetero atoms, optionally fused to a benzene ring, and optionally substituted by C- to C 8 hydrocarbyl; and wherein said polymeric suds stabilizer has a molecular weight of from about 1,000 to about 2,000,000 daltons; b) an effective amount of a detersive surfactant; and c) the balance carriers and other adjunct ingredients; provided the pH of a 10% aqueous solution of said composition is from about 4 to about 12. The present invention also relates to methods for providing increased suds and increased duration of suds while hand washing dishware comprising the step of dissolving a composition according to the present invention in water to form a hand dishwashing solution and then washing dishware by hand in said solution. These and other aspects, features and advantages will become apparent to those of ordinary skill in the art from a reading of the following detailed description and the appended claims. All percentages, ratios and proportions herein are by weight, unless otherwise specified. All temperatures are in degrees Celsius (°C) unless otherwise specified.

For the purposes of the present invention the term "pK a " stands equally well for the terms "pKj" and "pK " either separately or collectively. The term pK a as used herein throughout the present specification in the same manner as used by those of ordinary skill in the art. pK a values are readily obtained from standard literature sources, for example, "Critical Stability Constants: Volume 2, Amines" by Smith and Martel, Plenum Press, N.Y. and London, (1975). As an applied definition herein, the pK a values of the diamines are specified as being measured in an aqueous solution at 25° C having an ionic strength of from about 0.1 to about 0.5 M. As used herein, the pK a is an equilibrium constant dependent upon temperature and ionic strength, therefore, value reported by literature references, not measured in the above described manner, may not be within full agreement with the values and ranges which comprise the present invention. To eliminate ambiguity, the relevant conditions and/or references used for pK a 's of this invention are as defined herein or in "Critical Stability Constants: Volume 2, Amines".

Protease enzyme may be incorporated into the compositions in accordance with the invention at a level of from 0.0001%) to 2% active enzyme by weight of the composition. Amylase - Amylases (α and/or β) can be included for removal of carbohydrate-based stains. Suitable amylases are Termamyl® (Novo Nordisk), Fungamyl® and BAN® (Novo Nordisk). The enzymes may be of any suitable origin, such as vegetable, animal, bacterial, fungal and yeast origin.

Such Phadebas® α-amylase activity assay is described at pages 9-10, WO95/26397. (b) α-amylases according (a) comprising the amino sequence shown in the SEQ ID listings in the above cited reference, or an α-amylase being at least 80% homologous with the amino acid sequence shown in the SEQ ID listing.

A polypeptide is considered to be X% homologous to the parent amylase if a comparison of the respective amino acid sequences, performed via algorithms, such as the one described by Lipman and Pearson in Science 227, 1985, p. 1435, reveals an identity of X% (d) α-amylases according (a-c) wherein the α-amylase is obtainable from an alkalophilic Bacillus species; and in particular, from any of the strains NCIB 12289, NCIB 12512, NCIB 12513 and DSM 935. In the context of the present invention, the term "obtainable from" is intended not only to indicate an amylase produced by a Bacillus strain but also an amylase encoded by a DNA sequence isolated from such a Bacillus strain and produced in an host organism transformed with said DNA sequence. (e)α-amylase showing positive immunological cross-reactivity with antibodies raised against an α-amylase having an amino acid sequence corresponding respectively to those α-amylases in (a-d).

Said variants are described in the patent application PCT/DK96/00056. Other amylases suitable herein include, for example, α-amylases described in GB 1,296,839 to Novo; RAPID ASE®, International Bio-Synthetics, Inc. and TERMAMYL®, Novo. FUNGAMYL® from Novo is especially useful. Engineering of enzymes for improved stability, e.g., oxidative stability, is known. See, for example J. Biological Chem., Vol. 260, No. 11, June 1985, pp. 6518-6521. Certain preferred embodiments of the present compositions can make use of amylases having improved stability in detergents such as automatic dishwashing types, especially improved oxidative stability as measured against a reference-point of TERMAMYL® in commercial use in 1993. These preferred amylases herein share the characteristic of being "stability-enhanced" amylases, characterized, at a minimum, by a measurable improvement in one or more of: oxidative stability, e.g., to hydrogen peroxide/tetraacetylethylenediamine in buffered solution at pH 9-10; thermal stability, e.g., at common wash temperatures such as about 60°C; or alkaline stability, e.g., at a pH from about 8 to about 11, measured versus the above-identified reference-point amylase. Stability can be measured using any of the art-disclosed technical tests. See, for example, references disclosed in WO 9402597. Stability-enhanced amylases can be obtained from Novo or from Genencor International. One class of highly preferred amylases herein have the commonality of being derived using site-directed mutagenesis from one or more of the Bacillus amylases, especially the Bacillus α-amylases, regardless of whether one, two or multiple amylase strains are the immediate precursors. Oxidative stability- enhanced amylases vs. the above-identified reference amylase are preferred for use, especially in bleaching, more preferably oxygen bleaching, as distinct from chlorine bleaching, detergent compositions herein. Such preferred amylases include (a) an amylase according to the hereinbefore incorporated WO 9402597, Novo, Feb. 3, 1994, as further illustrated by a mutant in which substitution is made, using alanine or threonine, preferably threonine, of the methionine residue located in position 197 of the B. licheniformis alpha-amylase, known as TERMAMYL®, or the homologous position variation of a similar parent amylase, such as B. amyloliquefaciens, B. subtilis, or B. stearothermophilus; (b) stability-enhanced amylases as described by Genencor International in a paper entitled "Oxidatively Resistant alpha-Amylases" presented at the 207th American Chemical Society National Meeting, March 13-17 1994, by C. Mitchinson. Therein it was noted that bleaches in automatic dishwashing detergents inactivate alpha-amylases but that improved oxidative stability amylases have been made by Genencor from B. licheniformis NCIB8061. Methionine (Met) was identified as the most likely residue to be modified. Met was substituted, one at a time, in positions 8, 15, 197, 256, 304, 366 and 438 leading to specific mutants, particularly important being M197L and M197T with the M197T variant being the most stable expressed variant. Stability was measured in CASCADE® and SUNLIGHT®; (c) particularly preferred amylases herein include amylase variants having additional modification in the immediate parent as described in WO 9510603 A and are available from the assignee, Novo, as DURAMYL®. Other particularly preferred oxidative stability enhanced amylase include those described in WO 9418314 to Genencor International and WO 9402597 to Novo. Any other oxidative stability-enhanced amylase can be used, for example as derived by site-directed mutagenesis from known chimeric, hybrid or simple mutant parent forms of available amylases. Other preferred enzyme modifications are accessible. See WO 9509909 A to Novo. Various carbohydrase enzymes which impart antimicrobial activity may also be included in the present invention. Such enzymes include endoglycosidase, Type II endoglycosidase and glucosidase as disclosed in U.S. Patent Nos. 5,041,236, 5,395,541, 5,238,843 and 5,356,803 the disclosures of which are herein incorporated by reference. Of course, other enzymes having antimicrobial activity may be employed as well including peroxidases, oxidases and various other enzymes. It is also possible to include an enzyme stabilization system into the compositions of the present invention when any enzyme is present in the composition.

Carriers such as diethylphthalate can be used in the finished perfume compositions. Chelating Agents - The detergent compositions herein may also optionally contain one or more iron and or manganese chelating agents. Such chelating agents can be selected from the group consisting of amino carboxylates, amino phosphonates, polyfunctionally-substituted aromatic chelating agents and mixtures therein, all as hereinafter defined. 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. Amino carboxylates useful as optional chelating agents include ethylenediaminetetrace-tates, N-hydroxyethylethylenediaminetriacetates, nitrilo-tri- acetates, ethylenediamine tetrapro-prionates, triethylenetetraaminehexacetates, diethylenetriaminepentaacetates, and ethanoldi-glycines, alkali metal, ammonium, and substituted ammonium salts therein and mixtures therein. Amino phosphonates are also suitable for use as chelating agents in the compositions of the invention when at lease low levels of total phosphorus are permitted in detergent compositions, and include ethylenediaminetetrakis (methylenephosphonates) as DEQUEST. Preferred, these amino phosphonates to 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 dihydroxydisulfobenzenes such as 1,2- dihydroxy-3,5-disulfobenzene. A preferred biodegradable chelator for use herein is ethylenediamine disuccinate ("EDDS"), especially the [S,S] isomer as described in U.S. Patent 4,704,233, November 3, 1987, to Hartman and Perkins. The compositions herein may also contain water-soluble methyl glycine diacetic acid (MGDA) salts (or acid form) as a chelant or co-builder. Similarly, the so called "weak" builders such as citrate can also be used as chelating agents. If utilized, these chelating agents will generally comprise from about 0.1% to about 15% by weight of the detergent compositions herein. More preferably, if utilized, the chelating agents will comprise from about 0.1% to about 3.0%> by weight of such compositions. Composition pH Dishwashing compositions of the invention will be subjected to acidic stresses created by food soils when put to use, i.e., diluted and applied to soiled dishes. If a composition with a pH greater than 7 is to be more effective, it preferably should contain a buffering agent capable of providing a generally more alkaline pH in the composition and in dilute solutions, i.e., about 0.1% to 0.4% by weight aqueous solution, of the composition. The pKa value of this buffering agent should be about 0.5 to 1.0 pH units below the desired pH value of the composition (determined as described above). Preferably, the pKa of the buffering agent should be from about 7 to about 10. Under these conditions the buffering agent most effectively controls the pH while using the least amount thereof. The buffering agent may be an active detergent in its own right, or it may be a low molecular weight, organic or inorganic material that is used in this composition solely for maintaining an alkaline pH. Preferred buffering agents for compositions of this invention are nitrogen-containing materials. Some examples are amino acids such as lysine or lower alcohol amines like mono-, di-, and tri-ethanolamine. Other preferred nitrogen-containing buffering agents are Tri(hydroxymethyl)amino methane (HOCH 2 ) 3 CNH 3 (TRIS), 2-amino-2-ethyl-l,3-propanediol, 2-amino-2-methyl-propanol, 2-amino-2 -methyl- 1,3-propanol, disodium glutamate, N-methyl diethanolamide, 1,3- diamino-propanol N,N'-tetra-methyl-l ,3-diamino-2-propanol, N,N-bis(2- hydroxyethyl)glycine (bicine) and N-tris (hydroxymethyl)methyl glycine (tricine). Mixtures of any of the above are also acceptable. Useful inorganic buffers/alkalinity sources include the alkali metal carbonates and alkali metal phosphates, e.g., sodium carbonate, sodium polyphosphate. For additional buffers see McCutcheon's EMULSIFIERS AND DETERGENTS, North American Edition, 1997, McCutcheon Division, MC Publishing Company Kirk and WO 95/07971 both of which are incorporated herein by reference. The buffering agent, if used, is present in the compositions of the invention herein at a level of from about 0.1%) to 15%>, preferably from about 1% to 10%, most preferably from about 2% to 8%, by weight of the composition. Calcium and/or Magnesium Ions The presence of calcium and/or magnesium (divalent) ions improves the cleaning of greasy soils for various compositions, i.e., compositions containing alkyl ethoxy sulfates and/or polyhydroxy fatty acid amides. This is especially true when the compositions are used in softened water that contains few divalent ions. It is believed that calcium and/or magnesium ions increase the packing of the surfactants at the oil/water interface, thereby reducing interfacial tension and improving grease cleaning. Compositions of the invention herein containing magnesium and/or calcium ions exhibit good grease removal, manifest mildness to the skin, and provide good storage stability. These ions can be present in the compositions herein at an active level of from about 0.1%) to 4%, preferably from about 0.3%) to 3.5%, more preferably from about 0.5%) to 1%, by weight. Preferably, the magnesium or calcium ions are added as a hydroxide, chloride, acetate, formate, oxide or nitrate salt to the compositions of the present invention. Calcium ions may also be added as salts of the hydrotrope. The amount of calcium or magnesium ions present in compositions of the invention will be dependent upon the amount of total surfactant present therein. When calcium ions are present in the compositions of this invention, the molar ratio of calcium ions to total anionic surfactant should be from about 0.25:1 to about 2:1. Formulating such divalent ion-containing compositions in alkaline pH matrices may be difficult due to the incompatibility of the divalent ions, particularly magnesium, with hydroxide ions. When both divalent ions and alkaline pH are combined with the surfactant mixture of this invention, grease cleaning is achieved that is superior to that obtained by either alkaline pH or divalent ions alone. Yet, during storage, the stability of these compositions becomes poor due to the formation of hydroxide precipitates. Therefore, chelating agents discussed hereinbefore may also be necessary. Other Ingredients - The detergent compositions will further preferably comprise one or more detersive adjuncts selected from the following: soil release polymers, polymeric dispersants, polysaccharides, abrasives, bactericides, tarnish inhibitors, builders, enzymes, dyes, buffers, antifungal or mildew control agents, insect repellents, perfumes, opacifiers, hydrotropes, thickeners, processing aids, suds boosters, brighteners, anti-corrosive aids, stabilizers antioxidants and chelants. A wide variety of other ingredients useful in detergent compositions can be included in the compositions herein, including other active ingredients, carriers, hydrotropes, antioxidants, processing aids, dyes or pigments, solvents for liquid formulations, solid fillers for bar compositions, etc. If high sudsing is desired, suds boosters such as the Cjo-Ci6 alkanolamides can be incorporated into the compositions, typically at 1%-10%> levels. The C10-C14 monoethanol and diethanol amides illustrate a typical class of such suds boosters. Use of such suds boosters with high sudsing adjunct surfactants such as the amine oxides, betaines and sultaines noted above is also advantageous. An antioxidant can be optionally added to the detergent compositions of the present invention. They can be any conventional antioxidant used in detergent compositions, such as 2,6-di-tert-butyl-4-methylphenol (BHT), carbamate, ascorbate, thiosulfate, monoethanolamine(MEA), diethanolamine, triethanolamine, etc. It is preferred that the antioxidant, when present, be present in the composition from about 0.001%) to about 5% by weight. 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 surfactant before being absorbed into the porous substrate. In use, the detersive ingredient is released from the substrate into the aqueous washing liquor, where it performs its intended detersive function. To illustrate this technique in more detail, a porous hydrophobic silica (trademark SIPERNAT D10, DeGussa) is admixed with a proteolytic enzyme solution containing 3%-5%> of C j 3_25 ethoxylated alcohol (EO 7) nonionic surfactant. Typically, the enzyme/surfactant solution is 2.5 X the weight of silica. The resulting powder is dispersed with stirring in silicone oil (various silicone oil viscosities in the range of 500- 12,500 can be used). The resulting silicone oil dispersion is emulsified or otherwise added to the final detergent matrix. By this means, ingredients such as the aforementioned enzymes, bleaches, bleach activators, bleach catalysts, photoactivators, dyes, fluorescers, fabric conditioners and hydrolyzable surfactants can be "protected" for use in detergents, including liquid laundry detergent compositions. Further , these hand dishwashing detergent embodiments preferably further comprises a hydrotrope. Suitable hydrotropes include sodium, potassium, ammonium or water-soluble substituted ammonium salts of toluene sulfonic acid, naphthalene sulfonic acid, cumene sulfonic acid, xylene sulfonic acid. The detergent compositions of this invention can be in any form, including granular, paste, gel or liquid. Highly preferred embodiments are in liquid or gel form. Liquid detergent compositions can contain water and other solvents as carriers. Low molecular weight primary or secondary alcohols exemplified by methanol, ethanol, propanol, and isopropanol are suitable. Monohydric alcohols are preferred for solubilizing surfactant, 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-propanediol) can also be used. The compositions may contain from 5% to 90%, typically 10% to 50% of such carriers. An example of the procedure for making granules of the detergent compositions herein is as follows: - Linear aklylbenzenesulfonate, citric acid, sodium silicate, sodium sulfate perfume, diamine and water are added to, heated and mixed via a crutcher. The resulting slurry is spray dried into a granular form. An example of the procedure for making liquid detergent compositions herein is as follows: - To the free water and citrate are added and dissolved. To this solution amine oxide, betaine, ethanol, hydrotrope and nonionic surfactant are added. If free water isn't available, the citrate are added to the above mix then stirred until dissolved. At this point, an acid is added to neutralize the formulation.

Such compositions can contain various particulate detersive ingredients stably suspended therein. Such non-aqueous compositions thus comprise a LIQUID PHASE and, optionally but preferably, a SOLID PHASE, all as described in more detail hereinafter and in the cited references. The compositions of this invention can be used to form aqueous washing solutions for use hand dishwashing. Generally, an effective amount of such compositions is added to water to form such aqueous cleaning or soaking solutions. The aqueous solution so formed is then contacted with the dishware, tableware, and cooking utensils. An effective amount of the detergent compositions herein added to water to form aqueous cleaning solutions can comprise amounts sufficient to form from about 500 to 20,000 ppm of composition in aqueous solution. More preferably, from about 800 to 5,000 ppm of the detergent compositions herein will be provided in aqueous cleaning liquor. METHOD OF USE The present invention also relates to a method for providing increased suds volume and increased suds retention while hand washing dishware or cookware articles in need of cleaning, comprising the step of contacting said articles with an aqueous solution of a detergent composition suitable for use in hand dishwashing, said composition comprising: a) an effective amount of a polymeric suds stabilizer as herein before defined; b) an effective amount of a detersive surfactant; and c) the balance carriers and other adjunct ingredients; provided the pH of a 10% aqueous solution of said composition is from about 4 to about 12. The present invention also relates to a means for preventing the redeposition of grease, oils, and dirt, especially grease, from the hand washing solution onto dishware. This method comprises contacting an aqueous solution of the compositions of the present invention with soiled dishware and washing said dishware with said aqueous solution. An effective amount of the detergent compositions herein added to water to form aqueous cleaning solutions according to the method of the present invention comprises amounts sufficient to form from about 500 to 20,000 ppm of composition in aqueous solution. More preferably, from about 800 to 2,500 ppm of the detergent compositions herein will be provided in aqueous cleaning liquor. The liquid detergent compositions of the present invention are effective for preventing the redeposition of grease from the wash solution back onto the dishware during washing. One measure of effectiveness of the compositions of the present invention involves redeposition tests. The following test and others of similar nature are used to evaluate the suitability of the formulas described herein. A polyethylene 2 L graduated cylinder is filled to the 1 L graduation mark with an aqueous (water = 7 grain) solution comprising from about 500 to about 20,000 ppm of a liquid detergent composition according to the present invention. A synthetic greasy soil composition is then added to the cylinder and the solution is agitated. After a period of time the solution is decanted from the graduated cylinder and the interior walls of the graduated cylinder are rinsed with a suitable solvent or combination of solvents to recover any re-deposited greasy soil. The solvent is removed and the weight of greasy soil which remains in solution is determined by subtracting the amount of soil recovered from the amount initially added to the aqueous solution. Other re-deposition test include immersion of tableware, flatware, and the like and recovering any re-deposited soil. The above test can be further modified to determine the increased amount of suds volume and suds duration. The solution is first agitated then subsequently challenged with portions of greasy soil with agitation between each subsequent soil addition. The suds volume can be easily determined by using the vacant volume of the 2 L cylinder as a guide.
