Definitions
- the present invention relates to cleaning compositions, and in particular it relates to a liquid laundry detergent composition, that comprising a cationic polymer in a specific surfactant system for optimizing sudsing profile.
- the present invention also relates to methods of making and using such cleaning compositions.
- Sudsing profile is important for a cleaning composition, particularly laundry detergent, where the appropriate volume and speed of suds formation, retention and dissolution in the wash and rinse cycles are considered key benchmarks of performance by consumers.
- laundry detergents While a sudsing profile is important for machine washing process, it is even more important in a typical hand-washing process as the consumer would see changes in the suds level in the wash and rinse cycles.
- consumers particularly hand-washing consumers, desire laundry detergent that dissolves in the wash liquor to give voluminous suds during the wash cycle to signify sufficient performance. The suds are then carried over to the rinse solution and require additional time, water and labor to thoroughly rinse from the laundered fabric.
- a cleaning composition preferably a laundry detergent composition
- a laundry detergent composition which enables strong suds formation (e.g., fast generation of large volume of suds and/or stability or sustainability of the suds already generated over time) during the wash cycle while reducing and eliminating the suds quickly during the rinse cycle(s), preferably across a range of consumer wash habits and fabric/material surfaces being washed. It may be advantageous to have a laundry detergent composition that only requires a single rinse cycle to effectively remove the suds, thereby enabling the "single rinse" concept.
- conventional de-foaming or anti-foaming agents especially the polymeric de-foaming or anti-foaming agents, are known to cause significant whiteness loss in fabrics after repeated wash cycles, i.e., the grey or dull color in fabrics that have been exposed to many wash cycles. Therefore, the usage of such polymeric de-foaming or anti-foaming agents has been limited in laundry detergent compositions.
- the present invention relates to a laundry detergent composition which exhibits significant suds reduction during the rinse cycle while minimizing reduction of suds volume during the wash cycle, and at the same time leading to less fabric whiteness loss after repeated washing. It has now been discovered that the challenges presented hereinabove for conventional laundry detergents can be met by employing a specific cationic polymer in a unique surfactant system.
- the cationic polymer contains a first, nonionic monomeric unit derived from (meth)acrylamide (AAm), a second, cationic monomeric unit, and optionally a third, nonionic monomeric unit (which is not AAm) at a specific monomeric ratio and having a Molecular Weight within a specific range.
- Laundry detergent compositions containing the cationic polymer of the present invention demonstrate outstanding sudsing profile with no or little fabric whiteness loss. Absence of any silicone-derived structural component in such cationic polymer may help to optimize wash suds generation and stability while reducing/minimizing the cost of synthesis. Further, a surfactant system enriched with an alkylalkoxy sulfate (AES) surfactant is employed by the present invention to further improve the sudsing benefit of the cationic polymer.
- AES alkylalkoxy sulfate
- the present invention relates to a liquid laundry detergent composition, containing:
- the cationic polymer may contain one or more additional structural units other than (i), (ii), and (iii).
- the total mol% of all structural units contained by the cationic polymer adds up to be 100%.
- the total mol% of (i), (ii) and (iii) adds up to 100 mol%, i.e., the cationic polymer contains no other structural units than (i), (ii), and (iii).
- the second, cationic structural unit of the cationic polymer is derived or made from DADMAS, and more preferably derived or made from diallyl dimethyl ammonium chloride (DADMAC).
- DADMAS diallyl dimethyl ammonium chloride
- the third, nonionic structural unit may be made from a monomer which is vinylpyrrolidone (VP).
- VP vinylpyrrolidone
- the Molecular Weight of the cationic polymer ranges from 10,000 to 1,000,000 Daltons, more preferably from 15,000 to 700,000 Daltons, and most preferably from 20,000 to 350,000 Daltons.
- the present invention relates to a liquid laundry detergent composition that comprises:
- the present invention relates to a liquid laundry detergent composition, containing:
- sucher indicates a non-equilibrium dispersion of gas bubbles in a relatively smaller volume of a liquid.
- suds indicates a non-equilibrium dispersion of gas bubbles in a relatively smaller volume of a liquid.
- suds can be used interchangeably within the meaning of the present invention.
- sudsing profile refers to the properties of a detergent composition relating to suds character during the wash and rinse cycles.
- the sudsing profile of a detergent composition includes, but is not limited to, the speed of suds generation upon dissolution in the laundering liquor, the volume and retention of suds in the wash cycle, and the volume and disappearance of suds in the rinse cycle.
- the sudsing profile includes the Wash Suds Index and Rinse Suds Index, as specifically defined by the testing methods disclosed hereinafter in the examples. It may further include additional suds-related parameters, such as suds stability measured during the washing cycle and the like.
- the term "cleaning composition” means a liquid or solid composition for treating fabrics, hard surfaces and any other surfaces in the area of fabric and home care, and includes hard surface cleaning and/or treatment including floor and bathroom cleaners (e.g., toilet bowl cleaners); hand dishwashing agents or light duty dishwashing agents, especially those of the high-foaming type; machine dishwashing agents; personal care compositions; pet care compositions; automotive care compositions; and household care compositions.
- the cleaning composition of the present invention is a hard surface cleaning composition, preferably wherein the hard surface cleaning composition impregnates a nonwoven substrate.
- laundry detergent composition is a subset of "cleaning composition”, and includes a liquid or solid composition, and includes, unless otherwise indicated, granular or powder-form all-purpose or “heavy-duty” washing agents for fabric, especially cleaning detergents as well as cleaning auxiliaries such as bleach, rinse aids, additives or pre-treat types.
- the laundry detergent composition is a solid laundry detergent composition, and preferably a free-flowing particulate laundry detergent composition (i.e., a granular detergent product).
- charge density refers to the net charge density of the polymer itself and may be different from the monomer feedstock.
- Charge density for a homopolymer may be calculated by dividing the number of net charges per repeating (structural) unit by the molecular weight of the repeating unit.
- the positive charges may be located on the backbone of the polymers and/or the side chains of polymers.
- the charge density depends on the pH of the carrier.
- charge density is calculated based on the charge of the monomer at pH of 7. Typically, the charge is determined with respect to the polymerized structural unit, not necessarily the parent monomer.
- CCD Cationic Charge Density
- E2 is the molar equivalents of charge of the cationic structural unit
- C2 is the molar percentage of the cationic structural unit
- C1 and C3 are the molar percentages of the first and second (if any) nonionic structural units
- W1, W2 and W3 are the molecular weights in g/mol of the first, nonionic structural unit, the cationic structural unit, and the second nonionic structural unit (if any), respectively.
- mol% refers to the relative molar percentage of a particular monomeric structural unit in a polymer. It is understood that within the meaning of the present invention, the relative molar percentages of all monomeric structural units that are present in the cationic polymer shall add up to 100 mol%.
- the term "derived from” refers to monomeric structural unit in a polymer that can be made from a compound, or salts or acids thereof, or any derivative of such compound, i.e., with one or more substituents. Preferably, such structural unit is made directly from the compound in issue.
- structural unit derived from (meth)acrylamide refers to monomeric structural unit in a polymer that can be made from (meth)acrylamide, or salts or acids thereof, or any derivative thereof with one or more substituents.
- such structural unit is made directly from (meth)acrylamide.
- the term "(meth)acrylamide” refers to either methacrylamide or acrylamide, and it is abbreviated herein as "AAm.”
- ammonium salt or “ammonium salts” as used herein refers to various compounds selected from the group consisting of ammonium chloride, ammonium fluoride, ammonium bromide, ammonium iodine, ammonium bisulfate, ammonium alkyl sulfate, ammonium dihydrogen phosphate, ammonium hydrogen alkyl phosphate, ammonium dialkyl phosphate, and the like.
- diallyl dimethyl ammonium salts as described herein include, but are not limited to: diallyl dimethyl ammonium chloride (DADMAC), diallyl dimethyl ammonium fluoride, diallyl dimethyl ammonium bromide, diallyl dimethyl ammonium iodine, diallyl dimethyl ammonium bisulfate, diallyl dimethyl ammonium alkyl sulfate, diallyl dimethyl ammonium dihydrogen phosphate, diallyl dimethyl ammonium hydrogen alkyl phosphate, diallyl dimethyl ammonium dialkyl phosphate, and combinations thereof.
- the ammonium salt is ammonium chloride.
- the terms “comprising,” “comprises,” “include”, “includes” and “including” are meant to be non-limiting.

- SEC Size Exclusion Chromatography
- RI differential refractive index detection
- 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 ⁇ m pore size GVWP membrane filter (MILLIPORE, Massachusetts, USA).
- the RI detector needs to be kept at a constant temperature of 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 ⁇ L. Flow rate is set to 0.8 mL/min.
- 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 ⁇ m pore size nylon membrane (manufactured by WHATMAN, UK) into an auto sampler vial using a 5mL 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.
- the solution of 0.1M sodium chloride and 0.3% trifluoroacetic acid in DI water is first injected onto the column as the background.
- the weight-average molecular weight (Mw or "Molecular Weight”) 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.
- 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 following factors affect results and therefore should be controlled properly: (a) concentration of detergent in solution, (b) water hardness, (c) water 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 height generated during the washing stage by the laundry detergent containing the cationic polymer of the present invention or a comparative cationic polymer not falling within the scope of the present invention, versus control laundry detergent that does not contain any cationic polymer.
- the height of suds generated by each test 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.
- 2. Pour the sample aliquot to the tubes. Put in the rubber stopper and lock the tubes in place. 3.
- Average suds height of different categories described above are calculated by average the height data of each replicate.

Therefore, the lower the RSI percentage, the more suds reduction is effectuated during rinse, and the better the performance.
- a cationic polymer either an inventive cationic polymer with the specific monomeric composition and Molecular Weight as defined hereinabove, or a comparative cationic polymer not falling within the scope of the present invention
- An optimal sudsing profile as defined within the meaning of this invention includes a WSI of more than 70% and a RSI of less than 40%, preferably a WSI of more than 80% and a RSI of less than 30%, and more preferably a WSI of more than 100% (i.e., a suds boosting effect during wash) and a RSI of less than 20%.
- Test 4 Fabric Whiteness Loss Test (Fast Wash Method)
- the steps for assaying the whiteness maintenance of the laundry detergent of the present invention are as follows: (1) Formulation preparation: Formulate detergent compositions with or without polymers of interest. (2) Solution Preparation:
- WLP is the relative fabric whiteness loss (expressed in percentage) caused by a detergent composition containing a cationic polymer (which is typically known to cause some fabric whiteness loss) over that caused by a control detergent composition not containing such cationic polymer
- a larger WLP is indicative of more relative fabric whiteness loss observed in comparison with the control sample. Therefore, it is in turn indicative of poorer whiteness performance of the cationic polymer, i.e., its presence causes more fabric whiteness loss in the laundry detergent.
- the WLP is a negative number, it is indicative of the fact that the presence of the cationic polymer not only does not cause fabric whiteness loss, but actually imparts whiteness benefit to the fabric, which is the most desirable.
- the wash and rinse suds volumes of the laundry detergent compositions of the present invention can also be measured via the SITA Foam Tester (model: R-2000) made by SITA Messtechnik GmbH (Germany).
- the SITA Foam Tester R-2000 utilizes a patented rotor of defined geometry for foam generation. The rotor mechanically inserts air bubbles into the liquid. The foam volume is measured by an array of sensor needles, which scan the foam surface. Using an array of sensor needles permits exact measurement of the foam volume even with uneven foam surfaces. The output is given as average milliliters of foam height per measure. Foam height measurements are recorded every 10 seconds while stirring of the test composition continues - this occurs 15 times in total (i.e., resulting in 15 measurements in total).
- the Stir Count as used herein, means the total number of stirring intervals in one test.
- the instrument settings below are used in the suds volume measurements.
- the final suds volume for each detergent composition is the average of 6 suds readings from the 10 th to 15 th measurement.
- This method is used to evaluate the sudsing profile of laundry detergent and obtain a reading on wash suds and rinse suds volume.
- the following factors affect results and therefore should be controlled properly: (a) concentration of detergent in solution, (b) water hardness, (c) water temperature, (d) soil load in the solution, (e) instrument settings, and (f) cleanliness of the sample vessel of SITA.
- the performance is determined by comparing the suds volume generated by a laundry detergent containing the cationic polymer versus the laundry detergent without the cationic polymer.
- test liquid laundry detergent compositions are prepared, including: (1) a control composition containing no cationic polymer, (2) a first inventive composition containing 0.5 wt% of the inventive polymer 3 as described hereinabove in Table II of Example I; (3) a second inventive composition containing 0.5 wt% of the inventive polymer 4 as described hereinabove in Table II of Example I; (4) a third inventive composition containing 0.5 wt% of the inventive polymer 5 as described hereinabove in Table II of Example I; (5) a first inventive composition containing 0.5 wt% of the inventive polymer 11 as described hereinabove in Table II of Example I; (6) a second inventive composition containing 0.5 wt% of the inventive polymer 12 as described hereinabove in Table II of Example I; and (7) a third inventive composition containing 0.5 wt% of the inventive polymer 13 as described hereinabove in Table II of Example I.
- inventive compositions containing inventive cationic polymers of the present invention provide optimized sudsing profiles characterized by a satisfactory wash suds volume (a WSI of more than 70%) and significantly lower rinse suds volume (a RSI of less than 40%) in comparison with the control composition.
- the cationic polymers of the present invention also demonstrate observable sudsing benefit across different detergent dosing levels, i.e., the laundry detergent composition containing such cationic polymers may be added into water at different amounts to form laundering liquor of different detergent concentrations. Because different consumers may have very different dosing habits when it comes to laundry detergents, with some more prone to over-dosing and others more prone to under-dosing, it is an important advantage if the sudsing benefit of the present invention is observable across a wider dosing range, thereby accommodating different consumer dosing habits.
- test liquid laundry detergent compositions including: (1) a control composition containing no cationic polymer, (2) 5 inventive compositions, each of which containing the same ingredients as the control composition but further including 0.5 wt% of an inventive polymer within the scope of the present invention; and (3) 7 comparative compositions, each of which containing the same ingredients as the control composition but further including 0.5 wt% of a comparative polymer that has either AAm/DADMAC molar percentages falling outside of the scope of the present invention, or a Molecular Weight falling outside of the scope of the present invention.
- Sudsing Profile Test as described hereinabove is carried out for each of these thirteen (13) test compositions by dissolving each composition in water having a water hardness level of 16 gpg to form a laundering liquor containing 5000ppm of the test composition.
- the Sudsing Profile Test is repeated several times (the number of actual tests conducted for each test composition is listed at below), and the suds data provided hereinafter is obtained by averaging the data obtained from the repetition.
- the Wash Suds Index (WSI) and Rinse Suds Index (RSI) of each of the seven (7) comparative compositions and five (5) inventive compositions are calculated based on the wash suds volume and rinse suds volume measured for such compositions in comparison with the control composition.
- the comparative polymers contained in the comparative compositions have either AAm/DADMAC molar percentages or Molecular Weights falling outside of the scope of the present invention.
- the above data shows that only the inventive polymers with the appropriate AAm/DADMAC molar percentages and Molecular Weights provide optimal sudsing profiles, i.e., having a satisfactory wash suds volume quantified by a WSI of more than 70% and a sufficiently reduced rinse suds volume quantified by a RSI of less than 40%.
- Three (3) liquid laundry detergent compositions are prepared, including: (1) a control composition containing no cationic polymer, (2) a comparative composition containing 0.5 wt% of a comparative polymer, MerquatTM S, which contains 70 mol% of AAm and 30 mol% of DADMAC with a Molecular Weight of 3552.2K Dalton; (3) an inventive composition containing 0.5 wt% of the inventive polymer 2 as described hereinabove in Table II of Example I, MerquatTM 740, which contains 76 mol% of AAm and 24 mol% of DADMAC with a Molecular Weight of 61.5K Dalton.
- Fabric Whiteness Loss Test using the fast wash method as described in Test 4 hereinabove is carried out for each of these three (3) test compositions.
- the fabric used for conducting the test is polyester.
- the Whiteness Loss Index (i.e., ⁇ WLI) is measured for each of the control composition, the comparative composition, and the inventive composition.
- the Relative Whiteness Loss Percentage (WLP) of both the comparative composition and inventive composition are calculated based on their ⁇ WLI in comparison with that of the control composition. Following are the measurement results: Table X Control Composition Comparative Composition Inventive Composition ⁇ WLI 26.8 53.5 13.9 WLP 0% 99.6% -48.1% * Measured at 90-110 revolutions. ** Measured at 130-150 revolutions.
- WLP is the relative percentage fabric whiteness loss caused by a detergent composition containing a cationic polymer (either an inventive polymer or a comparative polymer) over that caused by a control detergent composition not containing such cationic polymer, the larger the WLP, the more relative fabric whiteness loss is caused by addition of the specific cationic polymer, which is indicative of poorer whiteness performance of such cationic polymer.
- the comparative polymer contained in the comparative composition and the inventive polymer 2 contained in the inventive composition have similar AAm and DADMAC molar percentages, but the inventive polymer 2 has a significantly lower Molecular Weight that falls within the scope of the present invention, while the comparative polymer has a high Molecular Weight that does not fall within the scope of the present invention.
- the comparative composition has a WLP as high as 99.6%, which is indicative of very poor whiteness performance of the comparative cationic polymer.
- the inventive composition has a negative WLP of -48.1%, which indicates that the presence of the inventive cationic polymer 2 not only does not cause fabric whiteness loss, but actually imparts whiteness benefit to the fabric tested.
- a total of six (6) test liquid laundry detergent compositions are prepared, which include: (1) a Composition A containing a LAS-enriched surfactant system without any cationic polymer; (2) Composition A plus a cationic polymer of the present invention, which contains 80 mol% of AAm, 16 mol% of DADMAC, and 4 mol% of VP and has a Mw of 165,300 Daltons; (3) a Composition B containing a NI-enriched surfactant system without any cationic polymer; (4) Composition B plus the cationic polymer; (5) a Composition C containing an AES-enriched surfactant system without any cationic polymer; and (6) Composition C plus the cationic polymer.
- the wash suds volume and the rinse suds volume of each test liquid laundry detergent composition are measured using the Sudsing Volume Test (SITA) described in Test 5.
- SITA Sudsing Volume Test
- wash Suds Change ⁇ Sw
- a positive ⁇ Sw is indicative of a wash suds boosting effect
- a negative ⁇ Sw is indicative of a wash suds suppressing effect. The more positive the ⁇ Sw, the stronger the suds boosting effect.
- ⁇ S R Rinse Suds Change
- a positive ⁇ S R is indicative of more rinse suds, which is undesirable, while a negative ⁇ S R is indicative of less rinse suds, which is desirable. The more negative the ⁇ S R , the stronger the suds suppressing effect.
- the overall sudsing benefit achieved by the inventive cationic polymer from the wash cycle to the rinse cycle is recorded as a Total Suds Change ( ⁇ S W - ⁇ S R ).
- heaving duty liquid detergents are made by mixing the ingredients listed below via conventional processes. Such heavy duty liquid detergents are used to launder fabrics that are then dried by line drying and/or machine drying. Such fabrics may be treated with a fabric enhancer prior to and/or during drying. Such fabrics exhibit a clean appearance and have a soft feel.
