[0074] A composition for treating fabrics, as disclosed herein, includes a fabric softening agent and an anti-adherent component that works for treating an aqueous carrier.

[0075] The composition for treating fabrics includes one or more fabric softening agents, which is a cationic softener selected from esterquats, imidazolinium quaternary cations, diammonium methyl sulfate, dichloride of certain compounds with the following formula: Petition 870250073490, dated 08 / 20 / 2025, p. 28 / 78 15 / 44 Formula 1: R1 (CH2)q—OC—R4 where R4 is an aliphatic hydrocarbon group with 8 to 22 carbon atoms, R2 and R3 represent (CH2)s-R5, where R5 is an alkoxycarbonyl group containing 8 to 22 carbon atoms, benzyl, phenyl, C1-C-4 alkyl-substituted phenyl, OH or H; Ri is (CH2)t-R6, where R6 is benzyl, phenyl, C1-C4 alkyl-substituted phenyl, OH or H; q, s, et, each independently, are an integer from 1 to 3; and X- is a softener-compatible anion.

[0076] Esterquat can be produced by the reaction of about 1.65 (1.5 to 1.75) mole of fatty acid methyl ester with one mole of alkane amine, followed by quaternization with dimethyl sulfate (more details on this). 3,915,867, which is incorporated herein in its entirety for all purposes). The use of these ratios controls the amount of each of monoesterquat, diesterquat, and triesterquat within the co-alkanol; it is desirable to increase the amount of diesterquat and minimize the amount of triesterquat to increase the amount of diesterquat. By selecting a ratio of approximately 1.65, the triesterquat can be minimized while increasing the monoesterquat. For example, when producing the esterquat by reacting the methyl fatty acid with an alkane amine at approximately 1.7:1, or approximately 1.65:1, the triesterquat can be minimized while increasing the monoesterquat. Petition 870250073490, dated 08 / 20 / 2025, p. 29 / 78 16 / 44

[0077] Monoesterquat is more water-soluble than triesterquat. Depending on Al, more or less monoesterquat is preferable. At high AI levels (typically at least 7%), more monoesterquat is preferable to triesterquat so that the esterquat is more water-soluble, allowing it to be distributed to the fabric during use. At reduced AI levels (typically down to 3%), less monoesterquat is preferable because, during use, the esterquat is desired to leave the solution and deposit on the fabric to soften it. They are adjusted to balance the solubility and distribution of the esterquat.

[0078] In certain embodiments, the reaction products are 50-65% by weight of diesterquat, 20-40% by weight of monoester, and 25% or less by weight of triester. In other embodiments, the amount of diesterquat is 52-60%, 53-58%, or 53-55% by weight. In other embodiments, the amount of monoesterquat is 30-40% or 35-40% by weight. In other embodiments, the amount of triesterquat is 1-12% or 8-11% by weight.

[0079] The percentages, by weight, of mono-, di-, and tri-esterquats, as described above, are determined by a quantitative analytical method. The percentages are necessary due to the presence of 10% to 15%, by weight, of non-quaternized species, such as... Consequently, normalized weight percentages refer to the % by weight of each of monoesterquat, diesterquat, and triesterquat; the % by weight is based on the total amount of monoesterquat, diesterquat, and triesterquat in the composition.

[0080] And saturated co Petition 870250073490, dated 08 / 20 / 2025, p. 30 / 78 17 / 44 Esterquat compositions using this percentage of saturated fatty acids do not have the processing disadvantages of 100% saturated materials. When used to soften fabrics, these compositions provide good fabric softness perception to the consumer while retaining good fragrance distribution. 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 up to 45%. In other embodiments, the amount is 50 to 70%, 55 to 65%, or 57.5 to 67.5%. For example, the percentage of saturated fatty acids based on the total weight of fatty acids can be approximately 45 to approximately 75%, approximately 45 to approximately 70%, approximately 45 to approximately 65%, approximately 45 to approximately 60%, approximately 45 to approximately 55%, approximately 70%, approximately 55 to approximately 75%, approximately 65%; approximately 60 to approximately 75%, approximately 60 to approximately 70%, approximately 65 to 75%.

[0081] In one embodiment, the percentage of fatty acid chains that are saturated is aci In this method, this can be obtained from a 50:50 ratio of hard:soft fatty acid. By hard, it is understood that the fatty acid is almost completely hydrogenated; by soft, it is understood that the fatty acid is only partially hydrogenated. And this partially hydrogenated fatty acid can be used. AND Petition 870250073490, dated 08 / 20 / 2025, p. 31 / 78 In a 18 / 44 formulation, the ratio is approximately 50:50. Since in these specific formulations, each of the hard and soft fatty acids covers ranges for different levels of saturation (hydrogenation), the actual percentage of fatty acids that are completely saturated can vary. In certain saturated and

[0082] The percentage of saturated fatty acids can be achieved using u percentage quantities of saturated fatty acids.

[0083] Fatty acids can be any fatty acid that is used to manufacture esterquats for fabric softening. Examples of fatty acids include synthesized tallow. In certain embodiments, the fatty acid is tallow. For example, the esterquat can be u L1 / 90, commercially available from Kao Chemicals, Tokyo, Japan.

For example, the non-stick component and / or co-softening agent may be polyquaternium-7. Polyquaternium-7 (PQ7) is a copolymer of acrylamide and diallyldimethylammonium chloride, and is typically represented by the following chemical formula: (CsH5nI)C1N1N1C5H5NO1N1. Polyquaternium-7 is commercially available as NOVERITE 300 from Lubrizol Corporation, Wickliffe, Ohio, and as FLOCARE LS737 from SNF Floerger, Andrézieux, France.

[0103] As described in this document, the inventors discovered surprising PQ7 offers considerable advantages. For example, PQ7 is typically supplied as a liquid dispersion. This facilitates its use in continuous manufacturing systems. PQ7 also forms stable mixtures compared to other liquid dispersions. Petition 870250073490, dated 08 / 20 / 2025, page 39 / 78 26 / 44 cannot be achieved by other polyquaternium polymers (e.g., Polyquaternium 67, Polyquaternium 5, etc.). The use of PQ7 also exhibited improved fragrance distribution at some key contact points that can treat tissues, including hydroxyethylcellulose dimethyl diallylammonium chloride copolymer (PQ-4), a terpolymer of acrylic acid, methacrylamide-propyl trimethylammonium chloride, and methyl acrylate (PQ-47).

[0105] In another embodiment, the amount of non-stick component and / or co-sticking agent can determine the amount of fabric to be replaced. That is, the inventors have discovered surprising fabrics (e.g., esterquat) of a known composition for co-stick care (e.g., wrinkle reduction, dispersion, etc.) by replacing them with a non-stick component and / or co-sticking agent with the characteristics of that amount of co-stick. Petition 870250073490, dated 08 / 20 / 2025, page 40 / 78 27 / 44 composition for tissue treatment can be determined by the following formula. Formula 2: Y = -0.0043X² + 0.0649X - 0.0037 where X is the amount of fabric softener (e.g., esterquat) to be replaced, and Y is the amount of non-stick component and / or co-softener (e.g., PQ7) needed to provide u of fabrics.

[0106] Formula 2 can be used to reduce the amount of agent a containing agent a by about 0.06% of anti-adherent component (e.g., polyquaternium-7). That is, a known tissue treatment composition containing esterquat can be modified to include 1% by weight less esterquat for every 0.06% by weight of polyquaternium-7 added. In another embodiment, 2% by weight of esterquat can be replaced by about 0.11% by weight polyquaternium-7, or 3% by weight of esterquat can be replaced by about 0.15% by weight polyquaternium-7.

[0108] The fabric treatment composition may be substantially free of fabric softeners, except for the fabric softening agent and the non-stick component. For example, in some embodiments, the fabric treatment composition is substantially free of any fabric softening agents, except for esterquat. In some embodiments, the fabric treatment composition is substantially free of any fabric softening agents and co-softening agents, except, respectively, for esterquat and polyquaternium-7.

For example, the thickener may be a crosslinked cationic polymer such as FLOSOFT DP200. FLOSOFT DP200 is commercially available through 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 to 100 mg percent of cationic vinyl addition monomer, 0 to 95 mg percent of acrylamide, and 70 to 300 ppm of a bifunctional vinyl addition monomer crosslinking agent.

[0115] Other suitable thickeners are water-soluble crosslinked cationic vinyl polymers that are crosslinked using a crosslinking agent of 300 ppm, preferably 75 to 200 ppm, and more preferably 80 to 150 ppm. These polymers are further described in US Patent 4,806,345, and other polymers that may be used are disclosed in WO 90 / 12862. Generally, such polymers are prepared as water-in-oil emulsions, in which the crosslinked polymers are dispersed in mineral oil, which may contain surfactants. During the manufacture of the finished product, in contact with the aqueous phase, the emulsion inverts, allowing the polymer copolymer to provide long-term stability to the composition for tissue treatment during storage and permitting the presence of relatively high levels of electrolytes without affecting the stability of the composition. Additionally, the amount of thickener is between 0.001 and 0.35. Petition 870250073490, dated 08 / 20 / 2025, page 44 / 78 31 / 44

[0123] To evaluate the formula under the most challenging conditions, a heterogeneous sample of pet hair is obtained from a grooming salon. The sample consists of hair samples from different dog breeds, with no further treatment applied after receiving the samples, including short and long hair, as well as in the presence of contaminants such as dust, dander, nails, and other unidentified components. The use of this complex mixture was selected as the worst-case scenario; and, as such, as the best option to evaluate the reduction of pet hair adhesion.

[0124] To determine the best way to assess the benefit, different types of tissue and methods of animal hair adhesion are used to determine The fabrics were selected taking into consideration their manufacturing materials, their popularity, and how differences in manufacturing techniques and surface roughness could affect the perceived benefit. The selected fabrics were cardigan, denim, and cotton.

[0125] For the analysis, 15 cm x 15 cm squares are cut from each type of fabric and marked with a circle 11.5 cm in diameter. This circle is drawn to define an area of ​​exposure between the animal hairs adhering to the fabric, which is restricted to the defined area (see FIG. 1). Petition 870250073490, dated 08 / 20 / 2025, page 47 / 78 34 / 44

[0126] For the exposure of tissues to animal hair, direct contact between the hair and the tissues is forced. Three different methods for adhering animal hair are used to obtain the most reproducible results.

[0127] Table 2 (below) describes the methods employed. The methods were identified as: A) Light; B) Medium; and C) Strong, to express the degree of physical contact between animal hair and fabric. For handling animal hair, rubber gloves were used to protect the fabrics. Large contaminants, such as nails and dirt particles, were detected. Table 2 Method | Amount of Hair Used (g) | Contact Time with Fabric (sec) | Type of Interaction [Animal Hair] [Fabric] | A | 1 | 60 | Light: Animal hair is deposited on the fabric covering the entire area of ​​the circle. After covering the entire area, place a 300g stainless steel container over the hair for 10 seconds, then remove and leave the Pet-Hair in contact with the fabric for 50 seconds. The animal hair is removed after 10 seconds of manual agitation. | B | 1 | 60 | Medium: Animal hair is deposited on the fabric covering the entire area of ​​the circle. After the entire area is covered, a stainless steel container is used to cover the animal hair (without applying pressure). Then, a circular motion is applied across the entire area of ​​the circle to rub the hair into the area for 60 seconds. | C | 1 | 60 | Strong: Animal hair is deposited on the fabric covering the entire area of ​​the circle.After the entire area is covered, the Pet-Hair is pressed against the fabric using a PET cap wrapped in aluminum foil. Then, a circular motion is applied across the entire area to rub the hairs into the area for 60 seconds.

[0128] Animal hairs adhered to all fabrics tested (jeans, cardigan and black cotton), however, the black cotton fabric allowed the Petition 870250073490, dated 08 / 20 / 2025, page 48 / 78 35 / 44 better contrast and thus facilitated the visual assessment of the tissues (see FIG. 2).

[0129] Regarding the different methods of animal hair adhesion, method A allowed for better reproducibility for animal hair deposition because less handling was required for its removal. Thus, for the remaining evaluations, cotton fabrics and method A were used for animal hair deposition on the fabric and subsequent benefit assessment. Example 2

[0130] The evaluation of the benefits was done by determining the amount of animal hair Table 3 Parameter Conditions Water Volume 60 L Wash Load Size 2.5 Kg Laundry Detergent Type Ariel Dobel Power Powder (P&G) Liquid Fabric Softener Dosage 34 mL / wash load Dryer Sheet 1 drying sheet / wash load Water Hardness Tap water (no hard water used) Drying Setting Tumble Dryer, 1 hour

[0132] Handling animal tissues and hair is always done with laboratory gloves. The procedure for adhering animal hair to tissues is as follows: 1. Weigh 1g of animal hair. 2. Remove any large particles, adhesive material, or any other debris. 3. flat surface. 4. Take the animal's hairs (from the laboratory) and unravel them to prevent large tangles from settling on the tissues (a confounding factor for visual assessments). 5. Place the animal hairs on the black cotton fabric, in the marked area of ​​the circle, trying to cover the entire inner surface, avoiding placing hairs outside the circle. 6. fifty (50) seconds. 7. Remove pet hair manually by grasping the fabric by both corners and shaking gently. 8. Cover the fabric with aluminum foil to prevent animal hair from getting in. [0 133] Visual assessments were conducted using the 2AFCM (untrained panelists u participants are asked to choose the piece of tissue with the most hairs.

[0139] As shown in FIG. 4, the greater the amount of esterquat (ESQ), the less the benefit (more hair adheres). On the other hand, modified polyquaternium-7 (mPQ7) shows a curved behavior that may be associated with its polyelectrolyte nature. As the amount of this CO on the surface increases, so does the dissipation of electrical charge. However, if the concentration continues to increase, it may be possible to obtain an excess of positive charge on the tissue surface which, instead of helping to reduce the adhesion of animal hairs, becomes the main reason for the formation of static charge.
