[0002] This application claims priority to U.S. Application No. 63 / 487,168, filed February 27, 2023, entitled “Compositions and Methods for Reducing Pet Hair Adhesion to Fabric,” the contents of which are incorporated herein by reference in their entirety for all purposes. Background Technology

[0003] Fabric care compositions are typically used during the rinsing or drying cycles of a washing process to improve various properties of washed fabrics, such as softness, fragrance, static reduction, and ironing ease. Liquid fabric care compositions are usually used in the rinsing cycle, while solid fabric care compositions are used in the drying cycle and are typically incorporated into a nonwoven substrate placed in the washer-dryer.

[0004] Pet hair adhering to fabrics is a problem that bothers many pet owners. The persistence of pet hair, especially during daily life, poses challenges to hygiene and aesthetics. Existing technologies aim to remove the hair during washing or dissolve it with peroxides during washing. However, these methods are not suitable for imparting a repellent barrier effect to the fabric. Other technologies apply active materials by completely melting them onto the fabric at high temperatures during the drying process. Still other methods describe spraying the ingredients onto the fabric.

[0005] The interactions between pet hair and fabric can be diverse. However, a significant portion of them have been shown to be based on electrostatic charge and the attraction resulting from opposite surface potentials between the fabric and the hair.

[0006] Therefore, it would be useful to develop more cost-effective fabric care compositions that reduce or prevent pet hair from adhering to fabrics. Embodiments of the present invention are designed to satisfy this and other objectives. Summary of the Invention

[0007] This summary is intended only to provide a brief overview of some aspects of one or more embodiments of the present disclosure. Other applicable areas of the present disclosure will become apparent from the detailed description provided below. This summary is not an exhaustive overview, nor is it intended to identify key or essential elements of the teachings, nor is it intended to define the scope of the disclosure. Rather, its purpose is merely to present one or more concepts as an introduction to the following detailed description.

[0008] This invention describes techniques to make fabrics less susceptible to hair adhesion, resulting in less hair being trapped on the surface during daily exposure and easier removal of any hair that eventually adheres and / or sticks. Therefore, this invention describes pet hair repellency and shielding techniques applied in the form of a fabric softener during a washing cycle.

[0009] Surprisingly, the addition of cationic surfactants and polymers to the washing process resulted in a significant and lasting reduction in pet hair adhesion. It is important to mention that this technology allows for the application of surface potential-altering substances from aqueous solutions, and thus can be integrated into the washing process. This is likely due to the substances used selectively targeting the fabric fibers in polar solvents such as water.

[0010] This technical approach has proven superior to existing technical solutions, including the melting process using dry-coating sheets as described above.

[0011] Some embodiments of the present invention provide a liquid fabric care composition comprising: water; dialkyl ester triethanolamine sulfate; and an effective amount of an anti-adhesion component comprising: a copolymer of organosilicon and / or acrylamide with diallyl dimethyl ammonium chloride, wherein the anti-adhesion component is present in an amount that effectively reduces the adhesion of pet hair to the fabric.

[0012] Other embodiments of the present invention provide a method for reducing or preventing the adhesion of pet hair to fabrics, the method comprising: applying a liquid composition to the fabric, the liquid composition comprising: water; dialkyl ester triethanolamine sulfate; and an effective amount of an anti-adhesion component comprising: an organosilicon and / or a copolymer of acrylamide and diallyl dimethyl ammonium chloride, wherein the anti-adhesion component is present in an amount that effectively reduces the adhesion of pet hair to the fabric.

[0013] In another embodiment, the viscosity of the fabric care composition is from 30 cP to 500 cP.

[0016] In another embodiment, the fabric softener mixture is a stable water-soluble liquid mixture.

[0017] In another embodiment, the amounts of ester quaternary ammonium salt and polyquaternary ammonium salt-7 in the fabric softening composition are based on the following formula I: Y = -0.0043X 2+0.0649X-0.0037, where X is the amount of the ester quaternary ammonium salt to be replaced, and Y is the amount of polyquaternary ammonium salt-7.

[0018] The foregoing and / or other aspects and uses embodied in this disclosure can also be achieved by providing a method for producing a fabric care composition with reduced ester quaternary ammonium salts, the method comprising: determining the amount of ester quaternary ammonium salts in a known fabric care composition; modifying the known fabric care composition by replacing x% by weight of the ester quaternary ammonium salts with x% by weight of polyquaternary ammonium salt-7; and producing a fabric care composition with reduced ester quaternary ammonium salts based on the modified fabric care composition, wherein the fabric care composition with reduced ester quaternary ammonium salts has at least equivalent properties to the known fabric care composition in terms of at least one of softness, ironing ease, and wrinkle reduction.

[0019] In another embodiment, the fabric care composition with reduced ester quaternary ammonium salts does not contain surfactants other than ester quaternary ammonium salts.

[0020] In another embodiment, the fabric care composition with reduced ester quaternary ammonium salt does not contain any other fabric softeners besides ester quaternary ammonium salt and polyquaternary ammonium salt-7.

[0021] In another embodiment, the viscosity of the fabric care composition with reduced ester quaternary ammonium salt is 50 cP to 300 cP.

[0022] In another embodiment, the fabric care composition with reduced ester quaternary ammonium salts further comprises an aqueous carrier; 0.3% to 3% by weight of a fragrance; 0.001% by weight or more of a thickener; and 0.2% by weight or less of a preservative.

[0102] Regarding the procedures, methods, techniques, and workflows disclosed herein, some operations may be combined and / or the order of some operations may be changed, based on the procedures, methods, techniques, and workflows of some implementation schemes.

[0103] The fabric care compositions disclosed herein include a fabric softener and an anti-adhesion component containing a co-softener. The fabric care compositions may be in liquid form and may contain an aqueous carrier.

[0104] The fabric care composition comprises one or more fabric softeners. In some embodiments, the fabric softener is selected from ester quaternary ammonium salts and imidazolines. Cationic fabric softeners, including quaternary ammonium salts, di-fatty acid dimethyl ammonium sulfate, di-tallow dimethyl ammonium chloride, and mixtures thereof. For example, in some embodiments, the fabric softener is an ester quaternary ammonium salt of the following formula:

[0105] Formula 1:

[0106]

[0107] R4 represents an aliphatic hydrocarbon group with 8 to 22 carbon atoms, while R2 and R3 represent (CH2). s -R5, where R5 is an alkoxycarbonyl, benzyl, phenyl, or C1-C group containing 8 to 22 carbon atoms. -4 Alkyl-substituted phenyl, OH, or H; R1 is (CH2). t -R6, where R6 is benzyl, phenyl, C1-C -4 Alkyl-substituted phenyl, OH, or H; q, s, and t are each independently an integer from 1 to 3; and X - It is an anionic softener.

[0108] The ester quaternary ammonium salt can be produced by reacting about 1.65 (1.5 to 1.75) moles of fatty acid methyl ester with 1 mole of alkanolamine, followed by quaternization with dimethyl sulfate (further details of this preparation method are disclosed in U.S. Patent No. 3,915,867, which is incorporated herein by reference in its entirety for all purposes). The ratio is used to control the amounts of the monoester quaternary ammonium salt, diester quaternary ammonium salt, and trimer quaternary ammonium salt in the composition. In some embodiments, the alkanolamine comprises triethanolamine. In some embodiments, it is desirable to increase the amount of the diester quaternary ammonium salt and minimize the amount of the trimer quaternary ammonium salt to improve the softening ability of the composition. By selecting a ratio of about 1.65, the trimer quaternary ammonium salt can be minimized while the monoester quaternary ammonium salt is increased. For example, by producing ester quaternary ammonium salts via reacting fatty acid methyl esters with alkanolamines in a molar ratio of about 1.5:1 to about 1.8:1, about 1.6:1 to about 1.7:1, or about 1.65:1, the production of triester quaternary ammonium salts can be minimized while the production of monoester quaternary ammonium salts can be increased.

[0109] Monoester quaternary ammonium salts are more soluble in water than trimer quaternary ammonium salts. Depending on the AI ​​(Alternative Intake), more or less monoester quaternary ammonium salt is desired. At higher AI levels (typically at least 7%), more monoester quaternary ammonium salt is desired compared to trimer quaternary ammonium salts, making the quaternary ammonium salt more soluble in water and allowing it to be delivered to the fabric during use. At lower AI levels (typically up to 3%), less monoester quaternary ammonium salt is desired because during use, it is expected that the quaternary ammonium salt will leave the solution and deposit on the fabric to achieve fabric softening. Depending on the AI, the amounts of monoester and trimer quaternary ammonium salts are adjusted to balance the solubility and delivery of the quaternary ammonium salt.

[0110] In some embodiments, the reaction product is 50% to 65% by weight of a diester quaternary ammonium salt, 20% to 40% by weight of a monoester, and 25% by weight or less of a trimer. In other embodiments, the amount of the diester quaternary ammonium salt is 52% to 60% by weight, 53% to 58% by weight, or 53% to 55% by weight. In other embodiments, the amount of the monoester quaternary ammonium salt is 30% to 40% by weight or 35% to 40% by weight. In other embodiments, the amount of the trimer quaternary ammonium salt is 1% to 12% by weight or 8% to 11% by weight.

[0111] The weight percentages of the monoester, diester, and trimer quaternary ammonium salts, as described above, were determined by quantitative analytical methods. The weight percentages of the monoester, diester, and trimer quaternary ammonium salts measured on the dried sample were normalized to 100%. Normalization is necessary because of the presence of 10% to 15% by weight of unquaternized substances, such as ester amines and free fatty acids. Therefore, the normalized weight percentages refer to the pure ester quaternary ammonium salt component of the raw material. In other words, for each of the monoester, diester, and trimer quaternary ammonium salts, the weight percentage is based on the total amount of the monoester, diester, and trimer quaternary ammonium salts in the composition.

[0112] In some embodiments, the percentage of saturated fatty acids is 45% to 75% based on the total weight of the fatty acids. Esters of quaternary ammonium salts using this percentage of saturated fatty acids do not experience the processing disadvantages of 100% saturated materials. When used for fabric softening, these compositions provide good consumer-perceived fabric softness while maintaining good fragrance delivery. In other embodiments, the amount is at least 50%, 55%, 60%, 65%, or 70%, up to 75%. In other embodiments, the amount does not exceed 70%, 65%, 60%, 55%, or 50%, down to a minimum of 45%. In other embodiments, the amount is 50% to 70%, 55% to 65%, or 57.5% to 67.5%. For example, based on the total weight of fatty acids, the percentage of saturated fatty acids can be about 45% to about 75%, about 45% to about 70%, about 45% to about 65%, about 45% to about 60%, about 45% to about 55%; about 50% to about 75%, about 50% to about 70%, about 50% to about 65%, about 50% to about 60%; about 55% to about 75%, about 55% to about 70%, about 55% to about 65%; about 60% to about 75%, about 60% to about 70%, about 65% to 75%, or any range or subrange thereof.

[0113] In one embodiment, the percentage of saturated fatty acid chains is approximately 62.5% by weight of the fatty acids. In this embodiment, this can be obtained from a 50:50 ratio of hard fatty acids to soft fatty acids. Hard means that the fatty acids are close to fully hydrogenated. In some embodiments, the fully hydrogenated fatty acids have an iodine value of 10 or less. Soft means that the fatty acids are not more than partially hydrogenated. In some embodiments, the iodine value of the partially hydrogenated fatty acids is at least 40. In some embodiments, the iodine value of the partially hydrogenated fatty acids is 40 to 55. The iodine value can be measured according to ASTM D5554-95 (2006). In some embodiments, the ratio of hard fatty acids to soft fatty acids is 70:30 to 40:60. In other embodiments, the ratio is 60:40 to 40:60 or 55:45 to 45:55. In one embodiment, the ratio is approximately 50:50. Because in these specific embodiments, hard fatty acids and soft fatty acids each cover a range of different saturation levels (hydrogenation), the actual percentage of fully saturated fatty acids can vary. In some implementations, soft tallow contains approximately 47% saturated chains by weight.

[0114] The percentage of saturated fatty acids can be achieved by preparing an ester quaternary ammonium salt using a mixture of fatty acids, or by blending the ester quaternary ammonium salt with different amounts of saturated fatty acids.

[0115] The fatty acid can be any fatty acid used to manufacture ester quaternary ammonium salts for fabric softening. Examples of fatty acids include, but are not limited to, coconut oil, palm oil, tallow, rapeseed oil, fish oil, or chemically synthesized fatty acids. In some embodiments, the fatty acid is tallow. For example, the ester quaternary ammonium salt can be a hydrogenated tallow ester quaternary ammonium salt, for example, commercially available from Kao Chemicals, Tokyo, Japan, TETRANYL L1 / 90.

[0116] Although ester quaternary ammonium salts can be provided in solid form, they are typically present in liquid form within a solvent. When in solid form, ester quaternary ammonium salts can be delivered by dry sheets in laundry. In some embodiments, the solvent includes water.

[0117] AI refers to the effective weight of a combination of monoester quaternary ammonium salts, diester quaternary ammonium salts, and trimer quaternary ammonium salts. Delivered AI refers to the mass (in grams) of ester quaternary ammonium salts used in a washing load. A load is 3.5 kg of fabric by weight. The delivered AI is adjusted proportionally as the load varies, for example, by using smaller or larger loads in a washing machine. In some embodiments, the delivered AI is 2.8 g / load to 8 g / load. In other embodiments, the delivered AI is 2.8 g / load to 7 g / load, 2.8 g / load to 6 g / load, 2.8 g / load to 5 g / load, 3 g / load to 8 g / load, 3 g / load to 7 g / load, 3 g / load to 6 g / load, 3 g / load to 5 g / load, 4 g / load to 8 g / load, 4 g / load to 7 g / load, 4 g / load to 6 g / load, or 4 g / load to 5 g / load.

[0118] In one embodiment, the fabric care composition contains 20% by weight or less of a fabric softener based on the total weight of the composition. In some embodiments, the fabric care composition contains 15% by weight or less, 10% by weight or less, or 5% by weight or less of a fabric softener. In other embodiments, the fabric care composition contains 3% by weight or less, 2% by weight or less, or 1% by weight or less of a fabric softener. For example, the fabric care composition may contain 4% by weight or less of quaternized triethanolamine diester. Typically, when included, the fabric care composition contains at least 0.5% by weight of a fabric softener. For example, based on the total weight of the fabric care composition, the amount of fabric softener in the fabric care composition can be from about 0.5 wt% to about 20 wt%, from about 0.5 wt% to about 15 wt%, from about 0.5 wt% to about 10 wt%, from about 0.5 wt% to about 5 wt%, from about 0.5 wt% to about 3 wt%, from about 0.5 wt% to about 2 wt%, from about 0.5 wt% to about 1 wt%; from about 1 wt% to about 20 wt%, from about 1 wt% to about 15 wt%, from about 1 wt% to about 10 wt%, from about 1 wt% to about 5 wt%, from about 1 wt% to about 3 wt%, from about 1 wt% to about 2 wt%; from about 1.5 wt% to about 20 wt%, from about 1.5 wt% to about 20 wt%.

In some cases, the weight-average molecular weight (Mw) of the organosilicon is preferably in the range of 2,000 to 200,000, for example, 5,000 to 100,000 or 10,000 to 50,000.

[0125] In some embodiments, the copolymer of acrylamide and diallyl dimethyl ammonium chloride is modified. In other embodiments, the copolymer of acrylamide and diallyl dimethyl ammonium chloride is linearly or branched hydrocarbon modified. In some embodiments, the liquid fabric care composition comprises about 0.01 wt% to about 2 wt% of the copolymer of acrylamide and diallyl dimethyl ammonium chloride.

[0129] In some embodiments, the liquid fabric care composition described herein reduces static electricity between pet hair and fabric.

[0130] In other embodiments, the liquid fabric care composition provides a hair adhesion benefit score of less than 50, optionally less than 49, less than 48, less than 47, less than 46, less than 45, less than 44, less than 43, less than 42, less than 41, less than 40, less than 39, less than 38, less than 37, less than 36, less than 35, less than 34, less than 33, less than 32, less than 31, less than 30, less than 29, less than 28, less than 27, less than 26, less than 25, less than 24, less than 23, less than 22, less than 21, or less than 20. The hair adhesion benefit score can be evaluated as described in Example 2. For example, the hair adhesion benefit score can be evaluated by visually assessing two fabric samples with equal amounts of hair, one sample being washed with detergent and the fabric care composition disclosed herein, and the other fabric sample being washed under the same conditions but with detergent only, and wherein the visual assessment involves multiple assessors (e.g., 4, 6, 8, 10, 20, 30 or more) assigning a score (if less hair) or two scores (if more hair) to the fabric sample compared to the fabric sample washed with detergent only, and then averaging the scores to determine the hair adhesion benefit score achieved by the fabric care composition.

[0131] Some embodiments of the present invention provide a liquid fabric care composition comprising: water; dialkyl ester triethanolamine sulfate; and an effective amount of an anti-adhesion component comprising: organosilicon; and / or a copolymer of acrylamide and diallyl dimethyl ammonium chloride; wherein the anti-adhesion component is present in an amount that effectively reduces the adhesion of pet hair to the fabric.

[0132] Other embodiments of the present invention provide liquid fabric care compositions for reducing or preventing pet hair adhesion to fabrics, comprising: dialkyl ester triethanolamine sulfate; organosilicon, or a copolymer of acrylamide and diallyl dimethyl ammonium chloride; and greater than about 50% by weight of water.

In some embodiments, the composition is a liquid composition comprising: water; dialkyl ester triethanolamine sulfate; and an effective amount of an anti-adhesion component comprising: organosilicon; and / or a copolymer of acrylamide and diallyl dimethyl ammonium chloride.

Still other embodiments of the present invention provide methods for reducing / preventing the adhesion of pet hair to fabrics, the methods comprising applying to the fabric a liquid composition comprising: water; dialkyl ester triethanolamine sulfate; and an effective amount of an anti-adhesion component comprising: organosilicon; and / or a copolymer of acrylamide and diallyl dimethyl ammonium chloride; wherein the anti-adhesion component is present in an amount that effectively reduces the adhesion of pet hair to the fabric.

[0135] As described herein, the inventors have unexpectedly discovered that PQ7 offers significant advantages compared to other polyquaternium polymers. For example, PQ7 is typically supplied as a liquid dispersion. This is advantageous for its use in continuous manufacturing systems. PQ7 also forms stable mixtures compared to mixtures using powdered or solid polyquaternium polymers. Given the lower amount of this material used, the fabric conditioning properties of PQ7 are also unexpected, and such properties may not be achievable with other polyquaternium polymers (e.g., polyquaternium 67, polyquaternium 5, etc.). The use of PQ7 also exhibits improved fragrance delivery at some key touchpoints important to consumers. Other polyquaternium polymers that may be included in fabric care compositions or, in some cases, not included in fabric care compositions include hydroxyethyl cellulose dimethyl diallyl ammonium chloride copolymer (PQ-4) and a terpolymer of acrylic acid, methacrylamide-propyltrimethylammonium chloride, and methyl acrylate (PQ-47).

[0136] In one embodiment, the fabric care composition contains up to 0.30% by weight of an anti-adhesion component (e.g., polyquaternium-7) based on the total weight of the fabric care composition. In other embodiments, the fabric care composition contains 0.05% to 0.25% by weight of an anti-adhesion component or 0.05% to 0.20% by weight of an anti-adhesion component. For example, the fabric care composition may contain 0.5% to 0.25% by weight of polyquaternium-7.

[0137] In another embodiment, the amount of the anti-adhesion component and / or co-softener in the fabric care composition can be determined by the amount of the fabric softener to be replaced. That is, the inventors have unexpectedly discovered a method to reduce the content of fabric softeners (e.g., ester quaternary ammonium salts) in known fabric care compositions with defined performance characteristics (e.g., softness, fragrance delivery, ironing ease, wrinkle reduction, dispersion, etc.) while maintaining similar or superior performance characteristics by replacing them with an anti-adhesion component and / or co-softener (e.g., PQ7). For example, the amount of the anti-adhesion component and / or co-softener in the fabric care composition can be determined by the following formula.

[0138] Formula 2:

[0139] Y = -0.0043X 2 +0.0649X -0.0037

[0140] Where X is the amount of the fabric softener to be replaced (e.g., ester quaternary ammonium salt), and Y is the amount of anti-adhesion component and / or co-softener (e.g., PQ7) required to provide similar performance to the amount of fabric softener in X.

[0141] Formula 2 can be used to reduce the amount of fabric softener in known fabric care compositions containing fabric softeners while maintaining comparable performance. For example, according to Formula 2, about 0.06% of the anti-adhesion component (e.g., polyquaternium-7) can replace 1% by weight of the fabric softener (e.g., ester quaternium-7). That is, known fabric care compositions containing ester quaternium-7 can be modified to contain 1% less ester quaternium-7 for every 0.06% by weight of polyquaternium-7 added. In another embodiment, about 0.11% by weight of polyquaternium-7 can replace 2% by weight of ester quaternium-7, or about 0.15% by weight of polyquaternium-7 can replace 3% by weight of ester quaternium-7.

[0142] In some embodiments, a combination of a fabric softener (e.g., an ester quaternary ammonium salt) and an anti-adhesion component (e.g., polyquaternary ammonium salt-7) forms a fabric softener mixture. The fabric softener mixture can form a stable liquid mixture that does not separate when stored at room temperature. The fabric softener mixture can form a water-soluble mixture.

[0143] Fabric care compositions may be substantially free of fabric softeners other than the fabric softener and anti-adhesion component. For example, in some embodiments, the fabric care composition is substantially free of any other fabric softener besides the ester quaternary ammonium salt. In some embodiments, the fabric care composition is substantially free of any other anti-adhesion component and / or co-softener besides polyquaternary ammonium salt-7. In some embodiments, the fabric care composition is substantially free of any other fabric softener and co-softener, respectively, besides the ester quaternary ammonium salt and polyquaternary ammonium salt-7.

[0144] Ester quaternary ammonium salts can be considered cationic surfactants. In some embodiments, the fabric care composition is substantially free of surfactants other than fabric softeners. For example, the fabric care composition is substantially free of surfactants other than ester quaternary ammonium salts. In some embodiments, the fabric care composition is substantially free of detergent surfactants. In another embodiment, the fabric care composition is substantially free of anionic surfactants.

[0145] Fabric care compositions may contain an aqueous carrier. For example, a fabric care composition may contain water as a carrier. In some embodiments, the amount of water is at least 30%, 40%, 50%, 60%, 70%, 80%, or 85% by weight of the composition. In one embodiment, the fabric care composition contains 25% by weight or more water based on the total weight of the composition. In other embodiments, the fabric care composition contains 50% by weight or more water, or 75% by weight or more water, based on the total weight of the composition.

[0146] In some embodiments, the fabric care composition may be a low-water or "concentrated" formulation intended for dilution prior to use. In such embodiments, the fabric care composition contains a low amount of an aqueous carrier. In some embodiments, the amount of water does not exceed 50 wt%, 40 wt%, 30 wt%, 20 wt%, 15 wt%, or 10 wt% of the composition. For example, based on the total weight of the fabric care composition, the fabric care composition may contain 50 wt% or less of water or 30 wt% or less of water.

[0147] Fabric care compositions may also contain other components, typically used in small amounts in the fabric care composition, to enhance the appearance or properties of the fabric care composition. For example, fabric care compositions may contain thickeners, fragrances, preservatives, colorants (e.g., dyes or pigments), bluing agents, bactericides, and opacifiers.

[0148] In some embodiments, the fabric care composition must be readily pourable by the end user. Therefore, for ready-to-use fabric care compositions, the viscosity should not exceed 500 centipoise (cP), preferably not exceeding 250 cP, and for fabric care compositions intended to be diluted before use, the viscosity should not exceed 10,000 cP. In one embodiment, the pourable viscosity of the fabric care composition is 30 cP to 500 cP, or 50 cP to 200 cP. Unless otherwise specified, viscosity is measured using a Brookfield RVTD digital viscometer with a No. 2 rotor at 50 rpm at 25°C.

[0149] To adjust viscosity, the fabric care composition may contain one or more thickeners. One or more thickeners may include water-soluble cationic polymer thickeners having a high molecular weight. For example, the thickener may be a crosslinked cationic polymer, such as FLOSOFT DP200. FLOSOFT DP200 is commercially available from SNF Floerger and is described in U.S. Patent No. 6,864,223 to Smith et al. FLOSOFT DP200 is a water-soluble crosslinked cationic polymer derived from the polymerization of 5 mol% to 100 mol% cationic vinyl adduct monomers, 0 mol% to 95 mol% acrylamide, and 70 ppm to 300 ppm difunctional vinyl adduct monomer crosslinking agents.

[0150] Other suitable thickeners are water-soluble crosslinked cationic vinyl polymers crosslinked with a crosslinking agent using a level of 70 ppm to 300 ppm, preferably 75 ppm to 200 ppm, and most preferably 80 ppm to 150 ppm of difunctional vinyl adduct monomers. These polymers are further described in U.S. Patent No. 4,806,345, and other polymers available are disclosed in WO 90 / 12862. Typically, such polymers are prepared as water-in-oil emulsions, wherein the crosslinked polymer is dispersed in a mineral oil that may contain a surfactant. During the manufacture of the finished product, upon contact with an aqueous phase, the emulsion is inverted, causing the water-soluble polymer to swell. The most preferred thickener can be a crosslinked copolymer of quaternary ammonium acrylate or methacrylate with an acrylamide comonomer. The thickener can provide long-term stability of the fabric care composition during storage and allows for relatively high levels of electrolytes without affecting the stability of the composition. Additionally, the fabric care composition remains stable when shear is applied to it. In some embodiments, the amount of the thickening polymer is at least 0.001% by weight. In other embodiments, the amount is from 0.001% by weight to 0.35% by weight.

[0151] In one embodiment, the fabric care composition contains 0.5% by weight or less of a thickener based on the total weight of the fabric care composition. In other embodiments, the fabric care composition contains 0.1% by weight or less of a thickener, or 0.05% by weight or less of a thickener based on the total weight of the fabric care composition.

[0152] Fabric care compositions may contain one or more fragrances, aromatic oils, or fragrances. As used herein, the term "fragrance" is used in its common sense to refer to and include any non-water-soluble aromatic substance or a mixture of naturally occurring (i.e., obtained by extraction from flowers, herbs, clusters of flowers, or plants), artificially occurring (i.e., mixtures of natural oils or oil components), and synthetically produced aromatic substances. As used herein, a fragrance or fragrance refers to an aromatic substance capable of providing a desired fragrance to fabrics and encompasses conventional substances commonly used in detergent compositions to provide a pleasant aroma and / or counteract unpleasant odors. Fragrances are generally liquid at ambient temperature, but solid fragrances may also be used. Fragrance substances include, but are not limited to, substances such as aldehydes, ketones, esters, etc., conventionally used to impart a pleasant aroma to laundry compositions. Naturally occurring plant and animal oils are also commonly used as components of fragrances.

[0153] Fabric care compositions may contain free fragrances, encapsulated fragrances, or a mixture of both.

[0154] In other embodiments, the fabric care composition may be provided as a fragrance-free composition. The amount of fragrance may be any desired amount, depending on the user's preference. In some embodiments, the total amount of fragrance is from 0.3% to 3% by weight, based on the total weight of the fabric care composition. The fragrance may be in free form, encapsulated form, or both.

[0155] Fabric care compositions may contain one or more preservatives. One or more preservatives may include one or more organic acids, such as lactic acid and / or phosphonic acid. For example, a fabric care composition may contain a combination of food-grade lactic acid and aminotrimethylphosphonic acid. In some embodiments, the fabric care composition may also contain isothiazolinones as preservatives. For example, one or more preservatives may include a mixture of (OIT / MIT / CIT) isothiazolinones. Suitable isothiazolinone preservatives include isothiazolinones sold under the trademark KATHON DP3 and available from Rohm & Haas.

[0156] In one embodiment, the fabric care composition contains 0.2% by weight or less of a preservative, based on the total weight of the fabric care composition. In other embodiments, the fabric care composition contains 0.15% by weight or less of a preservative, or 0.10% by weight or less of a preservative, based on the total weight of the fabric care composition.

[0157] Example

[0158] Example 1

[0159] Table 1 (hereinafter) describes exemplary compositions of the present invention (Example Compositions 1 to 5), which can be prepared by conventional methods known to those skilled in the art.

[0160] Table 1

[0161]

[0162] Example 2

[0163] To evaluate the formulation under the most challenging conditions, heterogeneous pet hair samples were obtained from a dog grooming shop. These samples consisted of hair from different dog breeds and had not undergone further processing upon receipt. This meant the use of a complex mixture of short and long hair, along with contaminants such as dust, dander, nails, and other unidentified components. This complex mixture was chosen as the worst-case scenario; and therefore, as the optimal option for evaluating the reduction of pet hair adhesion to fabrics.

[0164] To determine the best approach to assessing benefits, different types of fabrics and pet hair adhesion methods were used to determine the optimal conditions for the assessment. Fabrics were selected considering their manufacturing materials, their generality, and the differences in manufacturing techniques employed in their construction, to evaluate the potential impact of color, composition, and surface roughness on perceived benefits. The selected fabrics included knitted fabrics, denim, and cotton.

[0165] For analysis, 15cm x 15cm squares were cut from each fabric type and marked with a circle of 11.5cm diameter. This circle was drawn to define the exposed area between pet hair and the fabric. Similarly, the assessment of the amount of pet hair adhering to the fabric was limited to this defined area (see [reference needed]). Figure 1 ).

[0166] To expose the fabric to pet hair, direct contact between the hair and the fabric is forced. Three different methods for pet hair adhesion were evaluated to determine the optimal conditions for obtaining the most reproducible results.

[0167] Table 2 (below) describes the methods used. To indicate the degree of physical contact between pet hair and the fabric, the methods were defined as: A) light; B) moderate; and C) heavy. For pet hair treatment, rubber gloves were used to promote the formation of static electricity before the pet hair was deposited onto the fabric. Large contaminants (such as nails and dirt particles) and any hair tangles detected were removed manually.

[0168] Table 2

[0169]

[0170] Pet hair adhered to the fabrics tested (denim, knitted fabric, and black cotton); however, black cotton fabric allowed for the best contrast, thus facilitating visual evaluation of the fabric (see [link]). Figure 2 ).

[0171] Regarding different methods for pet hair adhesion, Method A allows for better reproducibility of pet hair deposition because less processing is required for pet hair removal. Therefore, for the remaining evaluation, cotton fabric and Method A were used for pet hair deposition on the fabric to further evaluate the benefits.

[0172] Example 2

[0173] Benefits are assessed by determining the amount of pet hair that adheres to the fabric after treatment with the exemplary composition of the present invention.

[0176] Groups of black cotton fabrics (15cm x 15cm) were treated with the amounts described in Table 3 (above). The black cotton fabrics were divided into several groups, one for each tested formulation. Each group of samples was washed individually under the conditions shown in Table 3 (above), such that each sample was washed with the exemplary composition of the present invention. The fabrics were dried in a tumble dryer for at least one (1) hour or until completely dry. An 11.5cm circle was marked on each fabric to define the area in contact with pet hair. The samples were stored on aluminum foil until use.

[0177] Laboratory gloves are always used when handling fabrics and pet hair. The procedure for handling pet hair adhesion to fabrics is as follows:

[0178] 1. Weigh 1g of pet hair

[0179] 2. Remove any large particles, adhesive materials, or any other contaminants from the sample (adjust the weight if necessary).

[0180] 3. Place a piece of black cotton fabric previously treated with the exemplary composition of the present invention on a flat surface.

[0181] 4. Pick up the pet hair with your hands (wearing lab gloves) and loosen the pet hair to avoid large tangles settling on the fabric (a distraction for visual assessment).

[0182] 5. Deposit pet hair into the circled area marked on the black cotton fabric, trying to cover the entire inner surface and avoiding depositing pet hair outside the circle.

[0183] 6. Place a 300g weight on the pet's fur for 10 (10) seconds. Remove the weight and let it sit for 50 (50) seconds.

[0184] 7. Manually remove pet hair by picking up the fabric from both corners and gently shaking it for ten (10) seconds.

[0185] 8. Cover fabric with aluminum foil to prevent pet hair from being removed by the wind.

[0186] Visual assessment was conducted using the 2AFCM (Two Alternative Forced Choice Method). This involved presenting untrained, specialized group members with a pair of fabrics containing pet hair. Participants were asked to choose the fabric with more hair.

[0187] To evaluate the hair adhesion benefit score, samples with more hair were rated as number 2, while samples with less hair were rated as number 1. Finally, a frequency analysis was performed to determine which samples had a higher hair adhesion benefit score (those selected most often for having the most hair). A higher hair adhesion benefit score indicated more hair adhering to the fabric, and a lower perceived benefit by the panel of experts.

[0188] To evaluate the potential benefits of liquid fabric softener formulations, different treatments were evaluated simultaneously. The treatments tested included:

[0189] 1. Detergent only

[0190] 2. Exemplary liquid compositions of the present invention

[0191] 3. Drying sheets

[0192] Washing was performed on black cotton fabrics according to the conditions described in Table 3. Pet hair adhesion and evaluation (2AFC method) were performed as described above. Each treatment was evaluated 24 times, and each individual treatment was evaluated 8 times. For example, the detergent was compared eight (8) times with the exemplary composition of the present invention (Example Composition 3), eight (8) times with dry sheets, and eight (8) times with the exemplary composition of the present invention (with a higher dosage). The results are shown in Table 4 (below) and Figure 3 As shown in the image.

[0193] Table 4

[0194] preparation Detergent Drying sheets Ex3 Ex3 Score 48 38 33 25

[0195] As from Figure 3 It can be seen that the exemplary composition of the present invention is far superior to detergents; and also shows a meaningful difference compared to dry sheets.

[0196] Example 3

[0197] The hair adhesion benefit score assesses the reduction in pet hair adhering to fabric. A lower score indicates a better benefit. The effects of certain components on pet hair adhesion were evaluated.

[0198] like Figure 4As shown, higher amounts of esterquaternium (ESQ) resulted in lower benefits (more hair adhesion). On the other hand, modified polyquaternium-7 (mPQ7) exhibited curved behavior, likely related to its polyelectrolyte properties. With increasing amounts of this component, surface conductivity increased, and charge dissipation also increased. However, if the concentration continued to rise, excessive positive charge could be generated on the fabric surface, which would not help reduce pet hair adhesion but rather tend to promote it due to the high potential difference between the fabric and pet hair. This high potential difference, without limitation to any particular theory, is considered the primary cause of static charge formation.

[0199] The hair adhesion benefit scores of various combinations of ESQ, mPQ7, and silicone were evaluated. The results are described in Table 5 below.

[0207] A 2AFCM method was used to evaluate and compare the hair adhesion benefit scores between the ESQ-based technology (Comp.Ex.1) and the exemplary composition of the present invention (ESQ+mPQ7). The results are described in Figure 5 middle.

[0208] Example 5

[0209] To evaluate the benefits of the exemplary liquid fabric care compositions of the present invention, evaluations were simultaneously conducted on both dog and cat hair using different treatments. The treatments tested are described in Table 6 (hereinafter). Each treatment included washing once with detergent (Comp. Ex. 2). The remaining treatments included using dry sheets (Comp. Ex. 3) or using the exemplary compositions of the present invention (Ex. 4).

[0210] Table 6

[0211]

[0212] *Ex.4 Evaluation is conducted in 1 single wash and 5 cumulative washes.

[0213] like Figure 6A and Figure 6B The figure shows the hair adhesion benefit scores for both dog and cat hair. As can be seen from the figure, less pet hair adheres to the fabric after treatment with the exemplary composition of the present invention.

[0214] A similar trend was observed in both assessments, with the sample treated only with detergent (Comp.Ex.2) selected as having the highest amount of adhered pet hair. The dryer sheet (Comp.Ex.3) followed as the second "most hairy" sample. Notably, the exemplary composition of the present invention (Ex.4) exhibited the lowest amount of pet hair adhered to the fabric.

[0215] Example 6

[0216] A 2AFCM evaluation was performed to compare the hair adhesion benefit scores between two exemplary compositions of the present invention: one based on ESQ + silicone (Ex. 4); and one based on ESQ + silicone + mPQ7 (Ex. 5). The results are described in... Figure 7 middle.

[0217] Example 7

[0218] The Acrylon fabric sample was washed. After a single wash, the Acrylon fabric sample was dried in a tumble dryer for 1 hour prior to testing. Initial static charge and static charge dissipation were measured using a 3M 718 electrostatic sensor. The dried Acrylon fabric sample was rubbed with a balloon twenty (20) times to form a static charge, and five (5) separate measurements (in kV) were performed according to the 3M 718 electrostatic sensor manufacturer's instructions. The main measurement scheme is shown in Table 1, in which continuous measurements were performed over time so that both the initial charge and the rate of charge dissipation could be measured.

[0221] Test the effect of ambient humidity to examine any significant changes caused by moisture absorption. Collect data and plot them for comparison.

[0222] The results are described in Table 8 (below). Two treatments and two environmental conditions were tested, and the static charge, measured in kV, was measured and compared between the treatments.

[0223] As demonstrated by the data described in Table 8 (hereinafter), less static charge is present after treatment with the exemplary composition of the present invention. Furthermore, static charge dissipation indicates that the charge present on the surface is reduced more rapidly after treatment with the exemplary composition of the present invention compared to treatment with detergent alone.

[0226] Example 8

[0227] A household consumer assessment was conducted to evaluate Example Composition 1. The household consumer assessment included 340 volunteers, with approximately equal numbers of male and female volunteers, whose homes were currently occupied by dogs or cats. Specifically, each volunteer was instructed to wash their clothes and / or fabrics using only the fabric detergent for two weeks. After two weeks of washing their clothes and / or fabrics with the fabric detergent alone, volunteers were provided with samples of Example Composition 1 for use for another two weeks according to typical instructions for using fabric conditioners. Volunteers completed a questionnaire after using Example Composition 1 for two weeks.

[0228] Based on the analysis of the questionnaire survey, 74.7% of the volunteers determined that Example Composition 1 produced fabrics and / or clothing that repelled pet hair, while 8.5% of the volunteers concluded that Example Composition 1 did not produce fabrics and / or clothing that repelled pet hair better than using fabric detergent alone, and 16.8% of the volunteers were unsure whether the Example Composition was better than using fabric detergent alone.

[0229] Example 9

[0230] According to the procedure described in the above embodiments, the benefit is evaluated by determining the amount of pet hair adhered to the fabric sample after treatment with exemplary composition 1. Specifically, a predetermined amount of hair (dog hair or cat hair) is applied to a fabric sample comprising 50% cotton and 50% polyester. The fabric sample is then treated with detergent only (Comp.Ex.2) or with detergent ( The liquid (P&G) and Example Composition 1 were washed under the following conditions: water volume 60 L; wash load consisting of a fabric sample plus a certain amount of cotton T-shirt, with a wash load of 2.5 kg; 27 mL detergent / wash load; and optionally 34 mL Example Composition 1 / wash load. The fabric sample and T-shirt were then tumble dried for one hour.

[0231] The fabric was then visually evaluated, and the observed proportions were compared with the theoretical proportions using a single-proportion z-test at a 95% confidence level using the following equation:

[0232] z = (p - p0) / √(p0(1 - p0) / n)

[0233] Where: p = the observed sample proportion; p0 = the assumed population proportion; and n = the sample size.

[0234] The summary of the benefit assessment results is shown in Tables 9 through 12.
