Description

  The present invention relates to the technical field of household fabric laundry compositions that provide fabric flexibility through washing and contain polymers.

  A number of consumer products are available for washing household fabrics. Similarly, there are a number of products that may be added during a standard washing machine rinse cycle or in a domestic dryer where softening and / or other care actives are applied to the fabric. This type of two- or three-step process has become very common for consumers seeking both excellent cleaning and fabric softening. However, this two or three step process is more time consuming and expensive than a single cleaning additive product. More recently, according to consumer demand, manufacturers of laundry detergent products have sought to provide one product that provides both fabric care, such as cleaning and flexibility, through washing.

  However, it is important to recognize that these two goals (cleaning and flexibility) are the exact opposite. Fabric cleaning generally results in the removal of dirt, allergens, stains, and other attached materials. In contrast, providing a care benefit (soft fabric feel) generally results from depositing beneficial care active materials on the fabric. Therefore, it is difficult to simultaneously perform cleaning (removal) and softening (adhesion) through cleaning. In the past, it has been recognized that, through cleaning, in cleaning and care products, attached care actives trap dirt or other materials on the fabric, resulting in a lightly soiled appearance that is clearly undesirable to the consumer. The deposited care active may itself leave a visible residue if it does not deposit uniformly on the fabric surface. Similarly, it has also been found that no care active is deposited or removed by a cleaning component.

  More recently, low levels of cationic polymers, referred to as “cationic adhesion aids”, have introduced various desirable benefit agents, fragrances, anti-wrinkle agents, hueing dyes to fabric fabrics for fabric softening. It has been recognized that adhesion can be improved. Such cationic deposition aids have been described in the art and generally include (1) a “natural” type comprising a carbohydrate moiety such as cationic hydroxyethyl cellulose or cationic guar gum, and (2) It falls into two classes, “synthetic”, which contain a cationic moiety but no carbohydrate. These “synthetic forms” are exemplified by copolymers of polyacrylamide (PAM) and methacrylamidepropyltrimethylammonium chloride (MAPTAC). One difficulty with the “natural” type is incompatibility with laundry detergent enzymes, particularly those with some cellulase activity.

  In addition, synthetic cationic deposition aids containing cationic and uncharged (nonionic) monomers now tend to leave an unsightly residue on the washed fabric at the laundry wash pH in the absence of anionic monomers. It was discovered. These residues are easily visible to the human eye when the washed fabric is dark in color. However, these discoveries are surprising in that previous disclosures of similar materials, such as US Pat. No. 6,949,498, provide only an indiscriminate list of cationic polymers in liquid laundry detergents. . Such disclosure merely provides a measure of the fabric softening effect associated with cationic polymers without any indication of visible residue, and much less disclosure of methods to alleviate such problems.

US Pat. No. 6,949,498

  Therefore, it would be highly desirable to identify improved laundry detergents that contain selected polymers that can provide good care to the fabric through washing while maintaining good cleaning and avoiding unsightly residues. I will.

  Surprisingly, a selection of polymers containing monomer units derived from a specific ratio combination of cationic monomers, nonionic monomers, and anionic monomers is a good cleaning agent. It has been discovered that care can be provided to fabrics through washing while maintaining clean and avoiding unsightly residues. Without being bound by theory, at laundry wash pH, such as from about 6 to about 11, the present polymers can adhere to the fabric surface in laundry operations, but are visible residues on the laundry fabric surface. It is thought to do so without leaving.

  All measurements referred to herein are at room temperature (about 21.1 ° C.) and atmospheric pressure unless otherwise specified.

  “Ampholytic” and “amphoteric” can be used interchangeably to describe a polymer comprising an anionic monomer unit and a cationic monomer unit.

It is pH which is.

  As used herein, “net charge” refers to the sum of the charge of monomer units comprising a polymer. The net charge of amphoteric and other ionic polymers may depend on conditions including, but not limited to, the soluble salt concentration of the polymer-containing carrier, such as pH, temperature, and the continuous phase of the aqueous dispersion.

  “Monomers”, as used herein, refers to molecules that can react by themselves or with other monomers or monomer units by chemical bonding to form polymers. “Monomer unit” as used herein refers to a chemically bonded unit in one polymer derived from one monomer.

  “Composition” as used herein may encompass the terms dispersion, solution, melt (such as a melt of pure liquid material), or fluid. “Dispersion” as used herein refers to a system of particles that may be uniformly distributed in a medium, which is then referred to herein as “continuous phase”. The term “aqueous dispersion” as used herein may include a dispersion of particles distributed in a continuous phase comprising water, which may include the present polymers.

  As used herein, “viscosity” refers to the flow resistance of a fluid due to shear forces. The viscosity of the fluid may depend on the conditions being measured, such as the fluid temperature.

  As used herein, the term “comprising” means that various components, ingredients, or steps can be used in combination in practicing the present invention. Thus, the term “comprising” encompasses the more restrictive terms “consisting essentially of” and “consisting of”. The composition can comprise, consist essentially of, or consist of any of the necessary and optional elements disclosed herein.

  As used herein, Markush language includes combinations of individual elements of a Markush group unless otherwise indicated.

  All percentages, ratios and proportions used herein are by weight percent of the composition, unless otherwise specified. All average values are calculated “by weight” of the composition or its components unless otherwise indicated.

Example I-Residue Test The presence of residue is evaluated in a full scale washing machine test using Miele Novotronic W527.

Residue experiment procedure The fabric used to assess the residue on the fabric was black velvet (material source: Denholme Velvets), Bradford, West Yorkshire, UK (Halifax Road, Denholme, Bradford, West Yorkshire, England) BD13 4EZ)-telephone (01274) 832 646, standard 150 cm CR Cotton Pile Velvet, quality 8897, black, 72% cotton, modal 28%).

  2. Sew a rectangular black velvet (dimensions 23.5cm x 47cm, folded to make a square with the velvet inward) using overlock stitching, leaving one open end and two sides A sachet is made by sewing. Turn the pouch inside out so that the velvet is on the outside.

  3. Dosing balls are filled with the recommended single dose of each product (125g) according to the instructions on the packaging for normal / medium soil and normal / medium water hardness cases. In each experiment, new and unused dosing balls are filled. Place the dosing ball in a black velvet pouch.

  4). The pouch is closed by folding it to a width of 2 cm along the opening side and fixed with three plastic stitches.

  5. For the cleaning test, a black sachet was placed in the back of the washing machine (Miele Novotronic W527) with the dosing ball opening up and no further ballast load. The washing machine is switched on using city water (2.5 mmol / L) using a wool washing program at 40 ° C. At the end of the washing cycle, the pouch is immediately removed from the washing machine. Open the pouch along three sides (all stitches and stitched side) except the folded side. For each test product, run with the reference product at the same time (for comparison). Each experiment is repeated twice to obtain 3 replicates per test product.

6). The sachets are dried overnight (horizontal on a flat surface) and then scored by two certified scorers using the following scoring instructions and criteria (relative criteria for the reference product results).

  To display less residue (rather than more residue), the sign of the above scale is inverted to a positive number.

  Each item is evaluated by two graders and the grade is averaged. If the grades given by the two judges differ by more than 1 PSU (excluding -1 and +1), repeat the scoring. Three replicates are evaluated and the results are averaged to obtain the final grade.

The above residue test was performed as a reference composition against the same composition containing one of the different copolymers listed in Table 3, using the standard composition described in Table 2 below.

The copolymers used and the results obtained are summarized in Table 3.

The total molar ratio is defined as: (% acrylic acid +% methacrylic acid) /
(% Acrylic acid +% methacrylic acid +% PamM APTAC)

  Based on consumer input, the difference in residue grade in this test is 2 PSUs from the reference composition (ie -2 or less PSU), giving the consumer an unsatisfactory residue level. Let's go. Thus, polymers that provide acceptable residue levels when included in the standard composition are polymers 2, 3, 5, and 7 in Table 2.

Example II-Softness Test The relative softness of fabrics washed with polymer-containing laundry products is evaluated in a full-scale washing machine test using Miele Novotronic W527.

Flexibility Experimental Procedures Fabric flexibility is a relative property and strategically examines various white fabric swatches washed with a standard single dose of laundry detergent in a commercial washing machine in this experimental procedure. Assessed by a trained flexibility scorer. The same fabric swatch set is washed separately with the reference laundry product and the test product. Flexibility results are a comparison of fabric samples obtained from washing with each test product with fabric samples obtained from washing with a reference detergent product using the following PSU scoring. All data are available on the commercial washing machine manufactured by Miele and sold as Novatronic W527 model and on the market manufactured by Miele and sold as Novotronic T490 model Obtained using a clothes dryer.

Fabric samples Cut several types of fabric samples and use them to evaluate flexibility. The fabric to use,
1) White pile, sample size 30cm x 30cm, weight 450g / m2, supplied by Maes Textiles-Waregem, Belgium 2) 100% white cotton knit, sample size 50cm × 40cm, weight 165-175g / m2, with 1/1 ribs, supplied by Abanderado (Industriepark West 61, 9100 Sint Niklaas, Belgium), and 3) white polycotton (50% polyester) Blended with 50% cotton), sample size 100cm x 120cm, weight 130g / m2, supplied by Dewerchin (Vruchtendreef 19, 8520 Kuurne, Belgium)

All fabric swatches used in the experimental procedure, including reference fabric swatches, are available for commercial Ariel Liquid (medium) to remove the manufacturer-applied glue (before testing). Using a standard amount of 75 ml, which is a recommended amount of dirt, moderate water hardness, administered from the dosing ball), at 60 ° C. for a short time (“white / colored”) standard program, city water (2.5 mmol / L).

  In addition to the fabric swatches, an additional ballast load was added in each wash cycle, so that the total weight of the fabric in the wash cycle was about 3 kg (see Table 4 below). The ballast load consists of two large pile towels (80 cm x 50 cm, supplied by Maes Textiles) and six cotton knits (50 cm x 50 cm, supplied by Abanderado). At the end of the three washing cycles, all fabrics are tumbled with a commercial dryer. When dry, the fabric is ready for use in the flexibility test.

Test load The fabric test load shown in Table 4 is used for the reference product and each of the test compositions.

Cloth swatch test The test load of the fabric is then dispensed with 75 ml of laundry product (medium water hardness, medium soil recommended single dose) to be analyzed, respectively, using a dosing ball. Wash 3 times (cycles 1, 2 and 3). The reference laundry product is washed under the same conditions as the test product.

  The washing machine is set to a standard program for a short time (“white / color”) supplied with city water (2.5 mmol / L) at 40 ° C. and rotating at 1200 rpm. To avoid contamination between products, do not replace the washing machine. For each laundry product test load, during cycles 1 and 2 and during cycles 2 and 3, the entire fabric was tumbled using the “Kastdrog” setting of the dryer and all 3 cycles were processed on the same day. Must be completed.

  After cycle 3, the fabric (shown in Table 4) that needs to be hung and dried is taken out and hung and dried overnight at a controlled temperature and humidity set at 21 ° C. and a relative humidity of 50%. Other fabrics are dried using the “Extra dry” setting in a tumbler dryer.

The day after drying, the fabric samples are scored using the PSU scale by two trained flexible scorers. The PSU scale referred to herein uses a -4 to 4 scoring standard with a pair of comparisons of a fabric sample treated with the test product and a fabric sample of the same type treated with the reference product. The PSU scoring criteria for this pair of comparisons are shown in Table 5 below.

  If the number of scoring criteria is positive, it helps that the fabric samples treated with the test product are more flexible than those of the reference product, and if the number of scoring criteria is negative, the reference sample is more flexible. Show. For a particular set of samples, if the grades given by the two flexible scorers differ by more than 1 PSU (except -1 and +1), re-evaluate.

  For each test product, the sample from the load (excluding the ballast load) is compared to a sample of the same fabric type washed with the reference product. Therefore, for each test, 32 PSU grades per grader (pile swatch hang drying score 8, pile tumbler dry score 8, cotton knit hang dry score 8, polycotton Complete tumble dry scoring 8).

  Finally, the average of the flexibility scores is calculated by averaging all 32 scores from both scorers.

Test Formulation The softness test described above was carried out using the commercially available fabric softening laundry detergent composition shown in Table 6 as a reference product, which is a table containing one of each of the different copolymers listed in Table 3. Comparison with a test composition according to the formulation described in 2.

The copolymers used in the test composition and the flexibility results obtained are summarized in Table 7.

  As can be seen by comparing the data outlined in Tables 3 and 7, incorporating polymer 2, 3 or 7 into the test composition of Table 2 has a good flexibility effect and an acceptable amount of fabric. Give both ground residues. Other polymers are included as comparative examples when incorporated into the test compositions of Table 2.
