Title: Cleaning compositions with improved sudsing profile comprising a cationic polymer and silicone mixture

Description:
FIELD OF THE INVENTION 
     The present invention relates to detergent or cleaning products, more preferably liquid laundry detergent products, and most preferably products that can be used for hand-washing fabrics. The detergent or cleaning products of the present invention contain foam control agents, namely a cationic polymer, an organomodified silicone and a siloxane-based diluent, and exhibit surprising and unexpected improvements in their sudsing profiles. 
     BACKGROUND OF THE INVENTION 
     Sudsing profile is important for a cleaning composition, particularly laundry detergents, where the appropriate volume and speed of suds formation, retention and disappearance in the wash and rinse cycles are considered key benchmarks of performance by the consumers. 
     Consumers viewed copious suds in the wash as the primary and most desirable signal of cleaning. High suds are especially desirable during hand washing of fabrics, since the consumer can directly feel and touch the suds generated during the wash cycle and will intuitively correlates the high suds volume with the achievement of sufficient fabric cleaning. 
     Paradoxically, while a large volume of suds is desirable during the wash cycle of fabric cleaning, it is nevertheless undesirable during the rinse cycle. If such high suds are still present during rinse, then the consumers immediately infer from it that there may still be surfactant residue on the fabrics and that the fabrics are not yet “clean”. As a result, the consumers feel the need to rinse the fabrics multiple times in order to make sure that the surfactants are removed as thoroughly as other soils. Because water is often a limited resource, especially in hand washing countries, the excess amount of water consumed by multiple rinses reduces the amount of water available for other possible uses, such as irrigation, drinking, bathing, etc. 
     Various foam-control or anti-foaming agents have been added to detergent for cleaning compositions to control and reduce the suds volume during the wash. For example, U.S. Pat. No. 8,536,109 (Dow Corning) discloses a foam control composition that contains a silicone anti-foam dispersed in an organopolysiloxane resin, wherein the silicone anti-foam includes an organopolysiloxane, an organosilicon resin, and a hydrophobic filler; U.S. Pat. No. 7,566,750 (Wacker) discloses a defoamer composition containing an organopolysiloxane, filler particles and/or an organopolysiloxane resin, and a very minor amount of added water, which is more effective in reducing the foam or suds volume. 
     However, the suds control benefit imparted by such foam control or anti-foaming agents may come at the expense of wash suds. Timing for release of the foam control or anti-foam agents is difficult to control. Correspondingly, inopportune release of the foam control or anti-foam agents may lead to significant reduction of the wash suds volume, which will give consumer the impression that the detergent or cleaning composition contains lower surfactant level and is therefore of lower quality/value. 
     Accordingly, there is a continuing need for better foam control or anti-foaming compositions that can further improve or optimize the sudsing profile of detergent or cleaning compositions, by achieving significant rinse suds reduction but at little or no expense to the wash suds, i.e., minimizing the wash suds reduction. 
     It would also be advantageous to formulate an improved detergent or cleaning composition that can generate ample suds during the wash cycle to delight the consumers but leaves little or no suds during the rinse cycle to enable a “single rinse” of the fabric for more cost saving and better environmental conservation. 
     SUMMARY OF THE INVENTION 
     The present invention discovers that a detergent or cleaning composition, especially a liquid laundry detergent composition, containing the combination of a cationic polymer with an organomodified silicone having one or more aryl moieties and a siloxane-based diluent having a Solubility Index of from 0.8 to 1.25 in the organomodified silicone (measured according to the test method described hereinafter) exhibits surprising and unexpected synergistic improvement in its sudsing profile. Specifically, the cationic polymer comprises a first nonionic structural unit derived from (meth)acrylamide (AAm), and a second cationic structural unit derived from an amine-containing monomer. The detergent or cleaning composition of the present invention is characterized by significant suds reduction during the rinsing cycle but little or no suds reduction during the washing cycle, in comparison with detergent or cleaning compositions that do not contain the above-described cationic polymer, organomodified silicone, and/or siloxane-based diluent. In certain embodiments, the detergent or cleaning compositions are characterized by an optimized sudsing profile sufficient to enable the “single rinse” concept. 
     In one aspect, the present invention relates to a detergent or cleaning composition containing: (a) a cationic polymer including a first nonionic structural unit derived from (meth)acrylamide (AAm) and a second cationic structural unit derived from an amine-containing monomer; (b) an organomodified silicone comprising one or more aryl moieties each including a 5- to 9-membered aromatic ring, wherein said aromatic ring can be either substituted or unsubstituted, either heteroatomic or homoatomic, either monocyclic or multicyclic; and (c) a siloxane-based diluent having a Solubility Index of from 0.8 to 1.25 in said organomodified silicone. In a preferred embodiment of the present invention, the detergent or cleaning composition further comprises hydrophobically modified silica, a silicone resin, and optionally an emulsifier. 
     In another aspect, the present invention relates to a detergent or cleaning composition containing: (a) from about 0.1% to about 1% by weight of a cationic polymer, which is an AAm/DADMAC copolymer or an AAm/DADMAC/VP terpolymer; (b) from about 0.2% to about 0.5% by weight of an organomodified silicone, which contains from about 10 mol % to about 40 mol % of siloxane units containing a 2-phenylpropyl moiety and from about 3 mol % to about 10 mol % of siloxane units containing a C 6 -C 10  alkyl moiety; (c) from about 0.2% to about 0.5% by weight of a siloxane-based diluent having a Solubility Index of from 0.85 to 1 in the afore-mentioned organomodified silicone, while the siloxane-based diluent includes a first polydimethylsiloxane polymer having a first, higher viscosity ranging from 8 cSt to 12 cSt and a second polydimethylsiloxane polymer having a second, lower viscosity ranging from 5 cSt to 10 cSt, when measured at a shear rate of 20 sec −1  and 25° C.; (d) from 0.02% to 0.05% by weight of a hydrophobically modified silica; and (e) from 0.01% to 0.05% by weight of a silicone resin. 
     The detergent or cleaning composition of the present invention may further contain one or more surfactants selected from the group consisting of anionic surfactants, nonionic surfactants, cationic surfactants, amphoteric surfactants, zwitterionic surfactants, and combinations thereof. The detergent or cleaning composition of the present invention is preferably a laundry detergent product and more preferably a liquid laundry detergent product. 
     Still another aspect of the present invention relates to the use of a detergent or cleaning composition as described hereinabove for hand-washing fabric to achieve optimized sudsing profile.

     Cationic Polymer 
     The cationic polymer used in the present invention is a copolymer that consists of at least two types of structural units. The structural units, or monomers, can be incorporated in the cationic polymer in a random format or can be in a blocky format. 
     In a particularly preferred embodiment of the present invention, such cationic polymer is a copolymer that contains only the first and second structural units as described hereinabove, i.e., it is substantially free of any other structural components, either in the polymeric backbone or in the side chains. In another preferred embodiment of the present invention, such cationic polymer is a terpolymer that contains only the first and second structural units as described hereinabove and an additional third structural unit, substantially free of any other structural components. Alternatively, it can include one or more additional structural units besides the first, second and third structural units described hereinabove. 
     The first nonionic structural unit in the cationic polymer of the present invention is derived from (meth)acrylamide (AAm). Preferably, the cationic polymer contains from about 5 mol % to about 99 mol %, preferably from about 25 mol % to about 98 mol %, more preferably from about 45 mol % to about 97 mol %, and most preferably from about 60 mol % to about 96 mol %, of the AAm-derived structural unit. 
     The second structural unit in the cationic polymer is a cationic structural unit that can be derived from any suitable water-soluble cationic ethylenically unsaturated monomer, such as, for example, N,N-dialkylaminoalkyl methacrylate, N,N-dialkylaminoalkyl acrylate, N,N-dialkylaminoalkyl acrylamide, N,N-dialkylaminoalkylmethacrylamide, methacylamidoalkyl trialkylammonium salts, acrylamidoalkylltrialkylamminium salts, vinylamine, vinyl imidazole, quaternized vinyl imidazole and diallyl dialkyl ammonium salts. 
     Preferably, the second cationic structural unit is derived from an amine-containing monomer selected from the group consisting of diallyl dimethyl ammonium salts (DADMAS), N,N-dimethyl aminoethyl acrylate, N,N-dimethyl aminoethyl methacrylate (DMAM), [2-(methacryloylamino)ethyl]tri-methylammonium salts, N,N-dimethylaminopropyl acrylamide (DMAPA), N,N-dimethylaminopropyl methacrylamide (DMAPMA), acrylamidopropyl trimethyl ammonium salts (APTAS), methacrylamidopropyl trimethylammonium salts (MAPTAS), and quaternized vinylimidazole (QVi). 
     More preferably, the second cationic structural unit is derived from a diallyl dimethyl ammonium salt (DADMAS), as described hereinabove. 
     Alternatively, the second cationic structural unit can be derived from a [2-(methacryloylamino)ethyl]tri-methylammonium salt, such as, for example, [2-(methacryloylamino)ethyl]tri-methylammonium chloride, [2-(methacryloylamino)ethyl]tri-methylammonium fluoride, [2-(methacryloylamino)ethyl]tri-methylammonium bromide, [2-(methacryloylamino)ethyl]tri-methylammonium iodine, [2-(methacryloylamino)ethyl]tri-methylammonium bisulfate, [2-(methacryloylamino)ethyl]tri-methylammonium alkyl sulfate, [2-(methacryloylamino)ethyl]tri-methylammonium dihydrogen phosphate, [2-(methacryloylamino)ethyl]tri-methylammonium hydrogen alkyl phosphate, [2-(methacryloylamino)ethyl]tri-methylammonium dialkyl phosphate, and combinations thereof.

     Still further, the second cationic structural unit can be derived from a MAPTAS, which includes, for example, methacrylamidopropyl trimethylammonium chloride (MAPTAC), methacrylamidopropyl trimethylammonium fluoride, methacrylamidopropyl trimethylammonium bromide, methacrylamidopropyl trimethylammonium iodine, methacrylamidopropyl trimethylammonium bisulfate, methacrylamidopropyl trimethylammonium alkyl sulfate, methacrylamidopropyl trimethylammonium dihydrogen phosphate, methacrylamidopropyl trimethylammonium hydrogen alkyl phosphate, methacrylamidopropyl trimethylammonium dialkyl phosphate, and combinations thereof. 
     More preferably, the second cationic structural unit is derived from DADMAC, MAPTAC, APTAC, or QVi. Most preferably, the second cationic structural unit as mentioned herein is made directly from DADMAC. 
     The second cationic structural unit is present in the cationic polymer in an amount ranging from about 1 mol % to about 95 mol %, preferably from about 2 mol % to about 75 mol %, more preferably from about 3 mol % to about 55 mol %, and most preferably from about 4 mol % to about 40 mol %. 
     The additional third structural unit, which is optional for the cationic polymer of the present invention, is a nonionic structural unit derived from a vinyl-based nonionic monomer, such as vinylpyrrolidone (VP), vinyl acetate, vinyl alcohol, vinyl formamide, vinyl acetamide, vinyl alkyl ether, vinyl pyridine, vinyl imidazole, vinyl caprolactam, and combinations thereof. More preferably, the third nonionic structural unit of the cationic polymer is derived from VP. The cationic polymer may contain from about 0 mol % to about 95 mol %, preferably from about 0 mol % to about 90 mol %, and more preferably from about 0 mol % to about 85 mol % of the third nonionic structural unit. 
     In a specific embodiment of the present invention, the cationic polymer does not contain any of the third nonionic structural unit (i.e., the third nonionic structural unit is present at 0 mol %) and consists essentially only of the first and second structural units as described hereinabove. For example, such cationic polymer can be a copolymer consisting essentially of: (i) from about 60 mol % to about 95 mol %, and preferably from about 65 mol % to about 90 mol %, of the AAm-derived first structural unit; (ii) from about 5 mol % to about 40 mol %, and preferably from about 10 mol % to about 35 mol %, of the second cationic structural unit as described hereinabove; and (iii) 0 mol % of the third nonionic structural unit. 
     In another specific embodiment of the present invention, the cationic polymer contains the first, second and third structural units as described hereinabove, and is substantially free of any other structural unit. For example, such cationic polymer can be a terpolymer consisting essentially of: (i) from about 60 mol % to about 95 mol %, and preferably from about 65 mol % to about 90 mol %, of the first nonionic AAm-derived structural unit as described hereinabove; (ii) from about 5 mol % to about 25 mol %, and preferably from about 10 mol % to about 35 mol %, of the second cationic structural unit as described hereinabove; and (iii) from about 0.1 mol % to about 86 mol %, and preferably from about 3 mol % to about 60 mol %, of the third nonionic structural unit as described hereinabove. 
     The preferred molar percentage ranges of the first, second, and optionally third structural units of the cationic polymer as specified hereinabove may help to further improve the sudsing profile generated by the laundry detergent compositions containing such cationic polymer during the wash and rinse cycles. 
     Molecular weights of the cationic polymers may also be modulated to help improving sudsing profile. Further, by modulating or controlling the molecular weights of the cationic polymers of the present invention, the whiteness loss that is commonly seen in fabrics after they have been exposed to multiple washes can be reduced or minimized Cationic polymers have been known to contribute to fabric whiteness loss, which is a limiting factor for wider usage of such polymers. However, inventors of the present invention have discovered that by controlling the molecular weight of the cationic polymer within a specific range, i.e., from about 1,000 to about 1,500,000 Daltons, preferably from about 10,000 to about 1,200,000 Daltons, and more preferably from about 20,000 to about 600,000 Daltons, the fabric whiteness loss can be effectively reduced in comparison with conventional cationic polymers. 
     The cationic polymer can be present in the detergent or cleaning composition of the present invention in an amount ranging from about 0.005% to about 10%, preferably about 0.01% to about 5%, more preferably from about 0.05% to about 3%, and most preferably from about 0.1% to about 1%, by total weight of the detergent or cleaning composition. In the event that such detergent or cleaning composition is a concentrated liquid laundry detergent composition, e.g., as a part of a unit-dose laundry detergent product (i.e., encapsulated by a single compartment or multi-compartment water-soluble pouch formed of a water-soluble polymeric film), the cationic polymer is preferably present in an amount ranging from about 0.2% to about 30%, more preferably from about 0.5% to about 20%, and most preferably from 1% to about 15%, by total weight of such concentrated liquid laundry detergent composition.

     The detergent or cleaning composition of the present invention further contains an organomodified silicone comprising one or more aryl moieties each comprising a 5- to 9-membered aromatic ring.

Preferably, the siloxane-based diluent is characterized by a Solubility Index of from about 0.85 to about 1.2, more preferably from about 0.9 to about 1.1, and most preferably from about 0.95 to about 1.0. 
     In a preferred but not necessary embodiment of the present invention, the siloxane-based diluent contains one or more polydimethylsiloxanes (PDMS) having viscosity ranging from about 0.5 cSt to about 10,000 cSt, preferably from about 1 cSt to about 1,000 cSt, more preferably from about 2 cSt to about 100 cSt, and most preferably from about 5 cSt to about 15 cSt, measured at a shear rate of 20 sec −1  and 25° C. The PDMS can be linear, branched, cyclic, grafted or cross-linked or cyclic structures, while linear PDMS is particularly preferred. 
     The siloxane-based diluent can be present in the detergent or cleaning composition of the present invention in an amount ranging from about 0.005% to about 10%, preferably from about 0.02% to about 5%, more preferably from about 0.05% to about 2.5%, and most preferably from about 0.2% to about 0.5%, by total weight of the detergent or cleaning composition. 
     In the event that such detergent or cleaning composition is a concentrated liquid laundry detergent composition, e.g., as a part of a unit-dose laundry detergent product (i.e., encapsulated by a single compartment or multi-compartment water-soluble pouch formed of a water-soluble polymeric film), the siloxane-based diluent is present in an amount ranging from about 0.02% to about 30%, preferably from about 0.1% to about 20%, more preferably from about 0.2% to about 10%, and most preferably from about 1% to about 5%, by total weight of such concentrated liquid laundry detergent composition.

     Method of Making the Detergent or Cleaning Composition 
     Incorporation of the above-described components and various other ingredients as described hereinabove into the detergent or cleaning compositions of the invention can be done in any suitable manner and can, in general, involve any order of mixing or addition. 
     For example, the cationic polymer, the organomodified silicone, the siloxane-based diluent, the hydrophobically modified silica, the silicone resin and the solvent as received from the manufacturer can be mixed first with a surfactant, such as an alkylalkoxy sulfate and preferably an alkylethoxy sulfate having a weight average degree of ethoxylation ranging from 0.1 to 5.0, to form a foam control composition, which is then mixed with two or more of the other components to form the final detergent or cleaning composition.

     Test Methods 
     Various techniques are known in the art to determine the properties of the compositions of the present invention comprising the cationic polymer. However, the following assays must be used in order that the invention described and claimed herein may be fully understood. 
     Test 1: Solubility Index Test—Measuring the Miscibility or Solubility of Materials in Organomodified Silicones Via UV-Vis % Transmittance 
     The Solubility Index is determined by measuring the percentage of light transmittance through samples using a UV-Vis Spectrophotometer operated in transmission mode, at 480 nm, using 1 cm path length cuvettes, in accordance with the following procedure. Suitable instruments include the Beckman Coulter model DU 800 UV-Vis Spectrophotometer (Beckman Coulter Inc., Brea, Calif., USA). 
     All sample preparations and analyses are conducted in a laboratory with air temperature of 22° C.+/−2° C. In a glass scintillation vial combine the predominant organocompatible silicone present in the composition, along with the material to be tested (for example, a polydimethyl siloxane polymer), at the ratio of 80:20 vol/vol. Cap the vial, and mix the materials thoroughly for 5 minutes using a benchtop vortex mixer set to its highest speed. If two or more distinct layers of materials are clearly visible by eye in the vial after mixing, then the Solubility Index of the test material is considered to be indeterminate via this method. If distinct layers are not clearly visible by eye, then continue with the analysis. 
     Turn on the spectrophotometer lamps and allow them to warm up for 30 minutes prior to commencing measurements. Set the instrument to collect the measurement in Percentage Transmission (% T) mode, at a wavelength of 480 nm Load all samples into 1 cm path length plastic cuvettes. If air bubbles are visible in the cuvettes, use a pipette to remove the bubbles, or let the bubbles settle out of the cuvette prior to measurement. 
     Zero the baseline for a neat sample of the organocompatible silicone by using a cuvette loaded with deionized (DI) water along with a cuvette loaded with the neat silicone. Measure the % T of the neat organocompatible silicone. Measure the % T of the mixture of organocompatible silicone and test sample, as prepared under the previous instructions. Compare the % T of the mixture of organocompatible silicone and test sample, to the % T of the neat organomodified silicone (which was measured using a DI water blank as a baseline). 
     The Solubility Index is reported as a decimal number, and is calculated as the % T of the mixture of organocompatible silicone and test sample, divided by the % T of the neat organocompatible silicone. For example, Solubility Index of a specific Test Sample A=% T of ABC in Organocompatible Silicone/% T of the Organocompatible Silicone=85%/98%=0.867 
     Test 2: Measurement of Weight Average Molecular Weight (Mw) 
     The weight-average molecular weight (Mw) of a polymer material of the present invention is determined by Size Exclusion Chromatography (SEC) with differential refractive index detection (RI). One suitable instrument is Agilent® GPC-MDS System using Agilent® GPC/SEC software, Version 1.2 (Agilent, Santa Clara, USA). SEC separation is carried out using three hydrophilic hydroxylation polymethyl methacrylate gel columns (Ultrahydrogel 2000-250-120 manufactured by Waters, Milford, USA) directly joined to each other in a linear series and a solution of 0.1M sodium chloride and 0.3% trifluoroacetic acid in DI-water, which is filtered through 0.22 μm pore size GVWP membrane filter (MILLIPORE, Massachusetts, USA). The RI detector needs to be kept at a constant temperature of about 5-10° C. above the ambient temperature to avoid baseline drift. It is set to 35° C. The injection volume for the SEC is 100 μL. Flow rate is set to 0.8 mL/min. Calculations and calibrations for the test polymer measurements are conducted against a set of 10 narrowly distributed Poly(2-vinylpyridin) standards from Polymer Standard Service (PSS, Mainz Germany) with peak molecular weights of: Mp=1110 g/mol; Mp=3140 g/mol; Mp=4810 g/mol; Mp=11.5 k g/mol; Mp=22 k g/mol; Mp=42.8 k g/mol; Mp=118 k g/mol; Mp=256 k g/mol; Mp=446 k g/mol; and Mp=1060 k g/mol. 
     Each test sample is prepared by dissolving the concentrated polymer solution into the above-described solution of 0.1M sodium chloride and 0.3% trifluoroacetic acid in DI water, to yield a test sample having a polymer concentration of 1 to 2 mg/mL. The sample solution is allowed to stand for 12 hours to fully dissolve, and then stirred well and filtered through a 0.45 μm pore size nylon membrane (manufactured by WHATMAN, UK) into an auto sampler vial using a 5 mL syringe. Samples of the polymer standards are prepared in a similar manner. Two sample solutions are prepared for each test polymer. Each solution is measured once. The two measurement results are averaged to calculate the Mw of the test polymer. 
     For each measurement, the solution of 0.1M sodium chloride and 0.3% trifluoroacetic acid in DI water is first injected onto the column as the background. A correction sample (a solution of 1 mg/mL polyethylene oxide with Mp=111.3 k g/mol) is analysed six times prior to other sample measurements, so as to verify repeatability and accuracy of the system. 
     The weight-average molecular weight (Mw) of the test sample polymer is calculated using the software that accompanies the instrument and selecting the menu options appropriate for narrow standard calibration modelling. A third-order polynomial curve is used to fit the calibration curve to the data points measured from the Poly(2-vinylpyridin) standards. The data regions used for calculating the weight-average molecular weight are selected based upon the strength of the signals detected by the RI detector. Data regions where the RI signals are greater than 3 times the respective baseline noise levels are selected and included in the Mw calculations. All other data regions are discarded and excluded from the Mw calculations. For those regions which fall outside of the calibration range, the calibration curve is extrapolated for the Mw calculation. 
     To measure the average molecular weight of a test sample containing a mixture of polymers of different molecular weights, the selected data region is cut into a number of equally spaced slices. The height or Y-value of each slice from the selected region represents the abundance (Ni) of a specific polymer (i), and the X-value of each slice from the selected region represents the molecular weight (Mi) of the specific polymer (i). The weight average molecular weight (Mw) of the test sample is then calculated based on the equation described hereinabove, i.e., Mw=(Σi Ni Mi2)/(Σi Ni Mi). 
     Test 3: Qualification of the Monomers by HPLC 
     Each of the monomers in the cationic polymer are quantified by high pressure liquid chromatography (HPLC) according to the follows: 
                                            Measuring device:   L-7000 series (Hitachi Ltd.)           Detector:   UV detector, L-7400 (Hitachi Ltd.)           Column:   SHODEX RSpak DE-413 (product of               Showa Denko K.K.)           Temperature:   40° C.           Eluent:   0.1% phosphoric acid aqueous solution           Flow Velocity:   1.0 mL/min                    
Test 4: Sudsing Profile Test
 
     The sudsing profile of the detergent or cleaning composition of the present invention is measured by employing a suds cylinder tester (SCT). The SCT has a set of 8 cylinders. Each cylinder is typically 32 cm long and 10 cm in diameter and may be together rotated at a rate of 20-22 revolutions per minute (rpm). This method is used to assay the performance of laundry detergent to obtain a reading on ability to generate suds as well as its suds stability and rinse suds performance. The following factors affect results and therefore should be controlled properly: (a) concentration of detergent in solution, (b) water hardness, (c) temperature of water, (d) speed and number of revolutions, (e) soil load in the solution, and (f) cleanliness of the inner part of the tubes. 
     The performance is determined by comparing the suds volume generated during the washing stage by the laundry detergent containing the foam control composition versus a laundry detergent without the foam control composition (i.e., control). The amount of suds present for the detergent alone and the detergent with the foam control composition is measured by recording the total suds height (i.e., height of suds plus wash liquor) minus the height of the wash liquor alone.
         1. Weigh the required amount of product and dissolve in 0.5 liters of 16 gpg (Ca:Mg=4:1) in desired hardness for at least 15 min Dissolve the samples simultaneously.   2. Pour the sample aliquot to the tubes. Put in the rubber stopper and lock the tubes in place.   3. Spin for 10 revolutions. Lock in an upright position. Then check the suds height very quickly (˜10 sec) left to right. Record the total suds height (i.e., height of the suds plus wash liquor) and the height of the wash liquor alone. This marks the after 10 revolutions data.   4. Spin for additional 20 revolutions. This marks the after 30 revolutions data. Take recordings from left to right.   5. Spin for 20 revolutions more. This marks the after 50 revolutions data. Take readings from left to right. Repeat this step one more time; thus, the data gathered are for after 70 revolutions.   6. Open the tubes. Add 1 piece of fabric stained with clay and ¼ piece of fabric stained with dirty cooking oil (DCO) into each tube. Spin for 20 revolutions. This marks the after 90 revolutions data. Take readings. Repeat this step one time; thus, the data gathered are for after 110 revolutions.
           (Note: The fabric pieces stained with clay are prepared as follows:
               Disperse 20 g of BJ-clay (clay collected from 15 cm below the earth surface in Beijing, China) into 80 ml of DI water via agitation to make a clay suspension.   Keep agitating the suspension during the preparation process, while brushing 2 g of such clay suspension onto the center of a piece of 10 cm*10 cm cotton fabric to form a round shape stain (d=5 cm).   The cotton fabric with clay is left dry at room temperature and then used for the performance evaluation.   
               The fabric pieces stained with DCO are prepared as follows:
               100 grams of peanut oil is used to fry 20 grams of salty fish for 2 hrs at 150-180° C. to form the dirty cooking oil (DCO).   Brush 0.6 ml of the DCO onto the center of a piece of 10 cm*10 cm cotton fabric to form a round shape stain (d=5 cm).   Cut the 10 cm*10 cm cotton fabric into 4 equal pieces and use one for the performance evaluation.)   
               
           7. Pour 62.5 mL solution out of the tube gently into 500 mL beaker. Add 16 gpg (Ca:Mg=4:1) hardness water into the beaker. Dispose of the remaining solution and wash the tube with tap water. Pour the 500 mL solution into the same tube.   8. Spin for 20 revolutions. This marks the after 130 revolutions data. Take readings from left to right. Repeat this step one time; thus data gathered are for after 150 revolutions.   9. Pour 250 mL solution out of the tube gently into 500 mL beaker. Add 16 gpg hardness water (Ca:Mg=4:1) into the beaker. Dispose of the remaining solution and wash the tube with tap water. Pour the 500 mL solution into the same tube. Repeat steps 8. Data gathered are for 190 revolutions data.

     Washing Suds Index (WSI) is calculated by the suds height generated by the control sample (WSH C ) during the wash cycle when suds stability is observed (i.e., 90-110 revolutions) divided by that generated by a test sample (WSH T ), i.e., containing either a cationic polymer, or an organomodified silicone with the siloxane-based dilute, or both, and then converted into a percentage, as follows:

     The WSI is indicative of how much suds is generated during the wash cycle by a test sample that may contain one or more ingredients having adverse impact on the wash suds, in comparison with the suds generated by a control sample that does not contain any of such ingredients. Therefore, the higher the WSI percentage, the more suds are generated during wash, and the better the performance. 
     Rinse Suds Index (RSI) is calculated by the suds height generated by the control sample (RSH C ) during the ⅛ rinse cycle (i.e., 130-150 revolutions) divided by that generated by a test sample (RSH T ), and then converted into a percentage, as follows:

     The RSI, on the other hand, is indicative of how much suds is left during the rinse cycle by a test sample containing one or more ingredients that may be effective in reducing the rinse suds, in comparison with the suds left by a control sample that does not contain any of such ingredients. Therefore, the lower the RSI percentage, the more suds reduction is effectuated during rinse, and the better the performance. 
     An Overall Sudsing Index (OSI) of a test sample versus the control sample is calculated as follows:

     The OSI is indicative of how the overall sudsing profile of a test sample containing one or more ingredients that may be effective in affecting either the wash suds or the rinse suds or both is compared with the overall sudsing profile of the control sample that does not contain such ingredients. If the OSI is positive, it is indicative that the overall sudsing profile of the test sample is better than that of the control sample. If the OSI is negative, it is indicative that the overall sudsing profile of the test sample is worse than that of the control sample. The larger the OSI value, the better the sudsing profile of the test sample in comparison with the control sample.

     The cationic polymers A-F as described hereinabove and/or the SRAF premix are mixed with AE3S at 2:2:1 ratio (based on active material) using an overhead blender or speed mixer to form a white foam control paste. The white foam control paste is then formulated into the base liquid detergent composition (Table II) to form a sample or test detergent composition for suds performance evaluation. The respective amounts of cationic polymer and SRAF are adjusted so as to provide 0.5 wt % of the polymer and 0.5 wt % of SRAF in the sample or test detergent composition for evaluation. A structurant such as hydrogenated castor oil may also be added to stabilize the sample or test detergent composition. 
     The Overall Suds Index (OSI) of each sample or test detergent composition formed thereby is tested using the method described in Test 3. The sample or test detergent compositions include: (1) a control composition that contains the base detergent composition alone, with neither any cationic polymer nor SRAF; (2) a comparative composition containing the base detergent composition with 0.5% SRAF alone, i.e., without any cationic polymer; (3) six comparative compositions each containing the base detergent composition with 0.5% of a cationic polymer alone, i.e., without SRAF; and (4) six inventive compositions each containing the base detergent composition with 0.5% of a cationic polymer and 0.5% SRAF. 
     The OSI results are summarized in the table below:

     It is clear from the OSI results provided hereinabove that the cationic polymers A-F and SRAF act together to improve the overall sudsing profile of the base detergent composition in a synergistic manner. When SRAF alone is added to the base detergent composition, it leads to a decrease, instead of an increase, in the OSI. When a cationic polymer alone is added to the base detergent composition, it leads to an increase in the OSI, but only to a limited extent. However, when SRAF and an inventive cationic polymer together are added to the base detergent composition, they result in an OSI increase that is significantly larger than that achieved by the cationic polymer alone. In other words, the SRAF, which results in poorer overall sudsing performance when added alone, functions to “spikes up” the overall sudsing performance when it is added in combination with an inventive cationic polymer of the present invention, which is both surprising and unexpected.
