Description

Technical Field

[0001] The present disclosure relates generally to laundry detergents and solid articles, and more particularly to laundry detergents and solid articles that exhibit reduced residue deposition on fabrics. Background Art

[0002] While effective at removing stains, some detergent formulations can introduce an undesirable buildup of residue on washed items, impacting appearance, fabric softness, and user comfort. This issue has become increasingly prominent as consumer expectations continue to rise, demanding not only excellent cleaning efficacy but also a residue-free look and feel after washing. The challenge lies in developing detergent compositions and convenient delivery formats that deliver superior stain removal while mitigating the tendency to leave unwanted residue on fabrics. Addressing this issue is crucial to meeting the growing preference for environmentally friendly and fabric-safe laundry solutions and aligning with the evolving standards of modern consumers.

[0003] The discussion of shortcomings and needs in the art prior to the present disclosure is in no way an admission that those skilled in the art recognized such shortcomings and needs prior to the present disclosure. Summary of the Invention

[0004] Various iterations have addressed the above problems and provided compositions, articles and methods useful for providing detergent compositions, and convenient forms for delivering those detergent compositions, which have excellent stain removal while reducing the tendency to leave unwanted residues on fabrics.

[0005] Various embodiments relate to laundry detergent compositions comprising a particulate material. The particulate material may comprise one or more particles that are at least partially insoluble in water. The at least one particle may comprise a first component, preferably an active component, and a second component, preferably an inactive component. The second component, preferably the inactive component, is at least partially insoluble in water and may have a dry particle size of about 0.01 μm to about 20 μm. Various embodiments relate to solid articles comprising a porous dissolvable sheet and a laundry detergent composition or at least the particulate material.

[0006] Various iterations relate to solid articles comprising a water-soluble, flexible, porous structure. The solid article may have one layer or multiple layers. The plurality of particles may be dispersed within a layer, between multiple layers, or a combination thereof. One, more than one, or each of the plurality of particles may comprise a first component, preferably an active component, and a second component, preferably an inactive component. Upon exposure to water at a temperature of 5° C. to 40° C., preferably about 10° C. to about 25° C., for a period of about 5 minutes to about 60 minutes, preferably about 10 minutes to about 20 minutes, at least about 50% to about 100%, preferably about 70% to 90%, of the plurality of particles may release at least some of the first component, preferably the active component, contained therein and have a particle size of about 0.01 μm to about 50 μm.

[0007] These and other features, aspects and advantages of the various iterations will become better understood with reference to the following description, drawings and claims. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] It should be understood that the various embodiments are not limited to the examples shown in the drawings. DETAILED DESCRIPTION

[0059] I. Definition

[0060] This disclosure is written to describe the present invention to those of ordinary skill in the art, and those of ordinary skill in the art will understand that the disclosure is not limited to the specific examples or embodiments described. The examples and embodiments are single instances of the present invention, which will make the greater scope apparent to those of ordinary skill in the art. Unless otherwise defined, all technical terms and scientific terms used herein have the same meaning as those commonly understood by those of ordinary skill in the art. It should also be understood that the terms used herein are not merely for the purpose of describing the examples and embodiments, and are not intended to be limiting, as the scope of the present disclosure will be limited only by the appended claims.

[0061] Unless otherwise expressly stated, all features disclosed in this specification (including any accompanying claims, abstracts and drawings) may be replaced by alternative features for the same, equivalent or similar purposes. Therefore, unless otherwise expressly stated, each feature disclosed is only an example of a general series of equivalent or similar features. The examples and embodiments described herein are for illustrative purposes only, and those of ordinary skill in the art will propose various modifications or changes based on these examples and embodiments, and these modifications or changes will be included in the spirit and scope of this application. Without substantially departing from the spirit and principles of the present disclosure, many changes and modifications can be made to the embodiments of the present disclosure. All such modifications and changes are intended to be included within the scope of the present disclosure herein. For example, unless otherwise indicated, the present disclosure is not limited to specific materials, reagents, reaction materials, manufacturing processes, etc., because they can vary. It should also be understood that the terms used herein are only used to describe the purpose of specific embodiments and are not intended to be limiting. It is also possible in the present disclosure that steps can be performed in different orders that are logically possible.

[0062] All numerical values herein are assumed to be modified by the term "about," whether or not explicitly stated. The term "about" generally refers to a range of values that one skilled in the art would consider equivalent to the stated value (e.g., having the same function or result). In many cases, the term "about" may include values that are rounded to the nearest significant figure.

[0063] In everyday usage, indefinite articles (such as "a") precede countable nouns, and uncountable nouns almost never take indefinite articles. Therefore, it must be noted that, as used in this specification and the claims that follow, the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to "a carrier" includes a plurality of carriers. In particular, when a singular countable noun is listed as an element in a claim, this specification will typically use phrases such as "single." For example, "a single carrier."

[0064] Unless otherwise indicated, all percentages indicating the amount of a component in a composition represent the percentage by weight of the component based on the total weight of the composition.

[0065] Where a numerical range is provided, it is understood that every intervening value, to the tenth of the unit of the lower limit unless the context clearly dictates otherwise, between the upper and lower limits of that range, as well as any other stated or intervening value in the stated range, is encompassed within the disclosure. The upper and lower limits of these smaller ranges may independently be included in the smaller ranges and are also encompassed within the disclosure, subject to any specifically excluded limit in the stated range. Where the stated range includes one or both of the limits, ranges excluding one or both of those included limits are also encompassed within the disclosure.

[0066] Throughout this specification and the claims that follow, reference will be made to a number of terms that are defined to have the following meanings, unless a contrary intention is apparent.

[0067] An "active ingredient" is the specific component or chemical substance in a preparation or product that is responsible for producing the intended functional effect.

[0068] "Inactive ingredients" refer to other ingredients or substances present in a preparation or product that do not constitute the primary active ingredient responsible for producing the intended functional effect.

[0069] "Particle size" can refer to the size of a single particle or the size of multiple particles (e.g., a cluster of particles). The particle size of a spherical object can be clearly and quantitatively defined by its diameter. However, typical material objects may be irregularly shaped and non-spherical. There are several ways to extend the term "particle size" to apply to non-spherical particles. Existing definitions are based on replacing a given particle or cluster with an imaginary sphere having one of the same properties as the particle. Volume-based particle size is equal to the diameter of a sphere with the same volume as the given particle. Area-based particle size is equal to the diameter of a sphere with the same surface area as the given particle or cluster. Weight-based particle size is equal to the diameter of a sphere with the same weight as the given particle or cluster. Hydrodynamic or aerodynamic particle size is equal to the diameter of a sphere with the same drag coefficient as the given particle or cluster.

[0070] Various particles may have a distribution of particle sizes. D50 and D100 are commonly used parameters in particle size distribution analysis, describing the median particle size and the maximum particle size, respectively. D50 represents the particle size at which 50% of the cumulative mass of particles is smaller, while D100 represents the particle size at which 100% of the cumulative mass of particles contained is smaller. D50 serves as the midpoint of the particle size distribution, representing the size in the middle of the distribution when the particles are arranged in ascending order. In contrast, D100 represents the maximum size of the particles in the distribution, where the cumulative distribution curve reaches 100%. The particles described herein may have a particle size distribution such that D50 is greater than about 150 microns and less than about 1700 microns.

[0071] The "dry particle size" of a material refers to the size of individual particles, aggregates, or agglomerates of the material when measured under low ambient relative humidity conditions, particularly at ambient temperature, where the ambient relative humidity is maintained below 15%. This measurement is performed to prevent or minimize any changes in particle size, structure, or properties due to moisture, ensuring that the size measurement accurately represents the characteristics of the material in the low humidity environment. Dry particle size can be determined using appropriate techniques and instrumentation, such as laser diffraction, dynamic light scattering, or similar methods appropriate to the material under consideration. Dry particle size measurements can provide valuable information for a variety of applications, including but not limited to the pharmaceutical, chemical, and materials industries, where maintaining low humidity conditions is critical to preserving the integrity and performance of the material.

[0072] The "average dry particle size" of a material is the average size of individual particles, aggregates, or agglomerates of the material when measured at low ambient relative humidity (less than 15%) and ambient temperature as defined for "dry particle size." This measurement is critical for a variety of applications, including pharmaceuticals, chemicals, and materials, where maintaining low humidity conditions is crucial to preserving material integrity and performance.

[0073] "Water-insoluble" refers to substances or materials that do not effectively dissolve or disperse in water under ordinary conditions. When a material is labeled "water-insoluble," it means that it exhibits limited or negligible solubility in water and that any attempt to dissolve it in water results in only minimal or undetectable changes in its physical state or chemical composition.

[0074] "At least partially water-insoluble" refers to a substance or material that, while not completely water-insoluble, has limited or restricted solubility in water under ordinary conditions. Unlike completely water-insoluble materials, those materials described as "at least partially water-insoluble" may exhibit some degree of solubility or dispersibility in water, but the degree of solubility is minimal, and they generally do not readily dissolve or disperse in water.

[0075] The "swelling index" is a numerical value that indicates the swelling capacity of a particle. It is calculated by dividing the volume or weight of a swollen particle after immersion in water at temperature T (°C) for time t (seconds) by the initial volume of the dry particle. The swelling index is a dimensionless number.

[0076]

[0077] "Swelling index adjusted particle size" is a quantitative measure that reflects the size of a single particle or the average size of a group of particles when they reach their maximum swelling capacity. The adjusted particle size is obtained by multiplying the particle size by the swelling index.

[0078] "Cellulose derivatives" are compounds or materials chemically modified from cellulose, a naturally occurring polysaccharide found in plant cell walls. Cellulose derivatives can be produced by modifying the structure of cellulose through various chemical methods to impart specific properties or functionality, such as improved solubility, increased flexibility, or enhanced compatibility with other materials. These modifications can produce a wide range of cellulose derivatives, non-limiting examples of which include cellulose acetate, hydroxyethyl cellulose (HEC), methyl cellulose, carboxymethyl cellulose (CMC), cellulose ethers (such as ethyl cellulose, hydroxypropyl cellulose, and hydroxypropyl methyl cellulose), and nitrocellulose.

[0079] A "crystalline material" is a substance or solid structure characterized by an ordered and repetitive arrangement of its constituent atoms, ions, or molecules in a three-dimensional lattice or framework. In a crystalline material, the atoms or particles are positioned with a high degree of periodicity, resulting in the formation of distinct, well-defined crystal structures. These materials exhibit specific and repeatable geometric patterns, called lattices, which give rise to the material's unique physical and chemical properties, including well-defined melting points, regular cleavage planes, and optical characteristics, such as birefringence. In contrast to crystalline materials are amorphous materials, whose atomic arrangements lack long-range order. Crystalline materials can include a wide range of substances, including metals, minerals, and various organic and inorganic compounds.

[0080] As used herein, "ambient conditions" refers to 23°C ± 1.0°C and 50% ± 2% relative humidity. The water-soluble solid particles may contain insoluble material that is dispersible into a suspension under aqueous washing conditions, with an average particle size of less than about 20 microns, or less than about 50 microns.

[0081] As used herein, the term "flexible" refers to the ability of an article to withstand stress without breaking or significantly rupturing when the article is bent 90° along a centerline perpendicular to its longitudinal direction. Preferably, such articles can undergo significant elastic deformation and are characterized by a Young's modulus of no greater than 5 GPa, preferably no greater than 1 GPa, more preferably no greater than 0.5 GPa, and most preferably no greater than 0.2 GPa.

[0082] As used herein, the term "solid" refers to the ability of an article to substantially retain its shape (ie, without any visible change in its shape) at 20°C and atmospheric pressure when the article is unrestrained and when no external forces are applied thereto.

[0083] As used herein, the term "sheet" refers to a non-fibrous structure having a three-dimensional shape, i.e., having a thickness, a length, and a width, and the length to thickness aspect ratio and the width to thickness aspect ratio are both at least about 5: 1, and the length to width ratio is at least about 1: 1. Preferably, the length to thickness aspect ratio and the width to thickness aspect ratio are both at least about 10: 1, more preferably at least about 15: 1, and most preferably at least about 20: 1; and the length to width aspect ratio is preferably at least about 1.2: 1, more preferably at least about 1.5: 1, and most preferably at least about 1.618: 1.

[0084] The term "substantially free" means that the indicated material is present at very small levels, is not intentionally added to the composition or product, or preferably is present in such a composition or product at levels that cannot be detected by analytical methods. This may include compositions or products in which the indicated material is present only as an impurity in one or more materials intentionally added to such composition or product.

[0085] Solid products

[0086] The solid article may be in the form of, for example, a flexible porous dissolvable solid sheet. Figure 1A and Figure 1B Schematic and cross-sectional views of an exemplary flexible porous dissolvable solid sheet 1 are shown, having opposing first and second planar surfaces 2 and 4. At least one particle 10 is located between the opposing first and second surfaces 2 and 4. The particle may be located in a matrix 20 formed from a water-soluble polymer, a surfactant, and optionally other auxiliary ingredients (not shown). Preferably, a majority, more preferably greater than 80%, still more preferably greater than 90%, and most preferably greater than 90%, of the particles 10 are located between the opposing first and second surfaces 2 and 4.

[0087] Flexible porous dissolvable solid sheets can be formed by the following processing steps or any process known in the art. The sheet and / or article can have a Young's modulus of no greater than 5 GPa, no greater than 1 GPa, no greater than 0.5 GPa, or no greater than 0.2 GPa. Such materials can completely dissolve or disperse in water without leaving visible solids or forming a visible separate phase when at least about 25 grams, at least about 50 grams, at least about 100 grams, or at least about 200 grams of the sheet and / or article is placed in one liter (1 L) of deionized water at 20° C. and atmospheric pressure and stirred thoroughly.

[0088] Typically, such solid sheets may be characterized by: (i) an open cell percentage of about 80% to 100%, about 85% to 100%, or about 90% to 100%, as measured by Test 3 below; and (ii) an overall average pore size of about 100 μm to about 2000 μm, about 150 μm to about 1000 μm, or about 200 μm to about 600 μm, as measured by the Micro-CT method described in Test 2 below. The overall average pore size can define the porosity of the OCF (open cell foam) structure. The open cell percentage can define the interconnectivity between the pores in the OCF structure. The interconnectivity of the OCF structure can also be described by the star volume or structural model index (SMI) as disclosed in WO2010077627 and WO2012138820.

[0089] Such solid sheets have opposing top and bottom surfaces, with the top surface thereof being characterized by a surface average pore size greater than about 100 μm, greater than about 110 μm, greater than about 120 μm, greater than about 130 μm, or greater than about 150 μm, as measured by the SEM method described below in Test 1. When compared to solid sheets formed by conventional heating / drying arrangements (e.g., convection-based, microwave-based, or impingement oven-based arrangements), the solid sheets formed by the improved heating / drying arrangement have a significantly larger surface average pore size at their top surface because, under the directional heating of the specially arranged arrangement, the top surface of the formed aerated wet premix sheet is the last to dry / solidify, and the bubbles near the top surface have the longest time to expand and form larger pore openings at the top surface.

[0090] The solid sheet is further characterized by an average pore wall thickness of about 5 μm to about 200 μm, about 10 μm to about 100 μm, or about 10 μm to about 80 μm, as measured by Test 2 below.

[0091] The solid sheet may contain a small amount of water. It is characterized by a final moisture content of 0.5% to 25%, 1% to 20%, or 3% to 10% by weight of the solid sheet, as measured by Test 4 below. The appropriate final moisture content in the resulting solid sheet ensures the desired flexibility / deformability of the sheet and provides a soft / smooth sensory feel to the consumer. If the final moisture content is too low, the sheet may be too brittle or too hard. If the final moisture content is too high, the sheet may be too sticky, and its overall structural integrity may be compromised.

[0092] The solid sheet may have a thickness in the range of about 0.6 mm to about 3.5 mm, about 0.7 mm to about 3 mm, about 0.8 mm to about 2 mm, or about 1 mm to about 2 mm. The thickness of the solid sheet may be measured using Test 6 described below. The solid sheet after drying may be slightly thicker than the aerated wet premix sheet due to the expansion of the pores and the resulting overall volume expansion.

[0093] The solid sheet may also be characterized by a basis weight of about 50 g / m 2 About 500g / m 2 , about 150g / m 2 About 450g / m 2 or about 250g / m 2 About 400g / m 2 , as measured by Test 6 described below.

[0094] Furthermore, the solid sheet may have a viscosity of about 0.05 g / cm 3 to about 0.5g / cm 3 , about 0.06g / cm 3 to about 0.4g / cm 3 , about 0.07g / cm 3 to about 0.2g / cm 3 or about 0.08g / cm 3 to about 0.15g / cm 3 The density of the solid sheet is lower than that of the aerated wet premix sheet, again due to the cell expansion and consequent overall volume expansion.

[0095] In some examples, the solid sheet may have a viscosity of about 0.06 g / cm 3 to about 0.16g / cm 3 , about 0.07g / cm 3 to about 0.15g / cm 3 or about 0.08g / cm 3 to about 0.145g / cm 3 A solid article containing a sheet material having such a relatively low density can achieve even more improved leakage performance.

[0096] Furthermore, the solid sheet may be characterized by a specific surface area of about 0.03 m 2 / g to about 0.25m 2 / g, about 0.04m 2 / g to about 0.22m 2 / g, 0.05m 2 / g to 0.2m 2 / g, 0.1m 2 / g to 0.18m 2 / g, as measured by Test 8 described below. The specific surface area of a solid sheet can indicate its porosity and can affect its dissolution rate, eg, the larger the specific surface area, the more porous the sheet and the faster its dissolution rate.

[0097] The solid sheet and / or dissolvable solid article may be characterized by:

[0098] · Open cell content of 85% to 100%, 90% to 100%; and / or

[0099] An overall average pore size of 150 μm to 1000 μm, 200 μm to 600 μm; and / or

[0100] Average pore wall thickness: 5μm to 200μm, 10μm to 100μm, 10μm to 80μm;

[0101] and / or

[0102] a final moisture content of 0.5% to 25%, 1% to 20%, 3% to 10% by weight of the solid sheet product; and / or

[0103] Thickness of 0.6mm to 3.5mm, 0.7mm to 3mm, 0.8mm to 2mm, 1mm to 2mm; and / or

[0104] Basis weight is about 50g / m 2 About 500g / m 2 , about 150g / m 2 About 450g / m 2 , about 250g / m 2 About 400g / m 2 and / or

[0105] Density: 0.05g / cm 3 to 0.5g / cm 3 , 0.06g / cm 3 to 0.4g / cm 3 , 0.07g / cm 3 to 0.2g / cm 3 , 0.08g / cm 3 to 0.15g / cm 3 and / or

[0106] Specific surface area is 0.03m 2 / g to 0.25m 2 / g, 0.04m 2 / g to 0.22m 2 / g, 0.05m 2 / g to 0.2m2 / g, 0.1m 2 / g to 0.18m 2 / g.

[0107] Solid product formulations

[0108] Water-soluble polymers

[0109] As mentioned above, the flexible porous dissolvable solid sheet can be formed from a wet premix comprising a water-soluble polymer and a first surfactant. Such a water-soluble polymer can be used as a film former, structurant, and carrier for other active ingredients (e.g., surfactants, emulsifiers, builders, chelating agents, fragrances, colorants, etc.) in the resulting solid sheet.

[0110] The wet premix may comprise from about 3% to about 20% water-soluble polymer by weight of the premix, and in one example from about 5% to about 15% water-soluble polymer by weight of the premix, and in one example from about 7% to about 10% water-soluble polymer by weight of the premix.

[0111] After drying, the water-soluble polymer may be present in the flexible porous dissolvable solid sheet in an amount ranging from about 5% to about 60%, from about 7% to about 50%, from about 9% to about 40%, from about 10% to about 30%, for example, 10%, 12%, 15%, 18%, 20%, 25%, 30%, or any range therebetween, based on the total weight of the solid sheet. The total amount of water-soluble polymer present in the flexible porous dissolvable solid sheet may be no more than 25% by weight of the total weight of such sheet.

[0112] Suitable water-soluble polymers for use herein can be selected from those having a weight average molecular weight in the following ranges: about 5,000 to about 400,000 daltons, about 10,000 to about 300,000 daltons, about 15,000 to about 200,000 daltons, about 20,000 to about 150,000 daltons. The weight average molecular weight is calculated by multiplying the average molecular weight of each polymer raw material by the relative weight percentages of the total weight of the polymers present in the porous solid sheet. The weight average molecular weight of the water-soluble polymer used herein can affect the viscosity of the wet premix, which can in turn affect the number and size of bubbles during the aeration step and the pore expansion / opening results during the drying step. In addition, the weight average molecular weight of the water-soluble polymer can affect the overall film-forming properties of the wet premix and its compatibility / incompatibility with a specific surfactant.

[0113] Water-soluble polymers may include, but are not limited to, synthetic polymers including polyvinyl alcohol, polyvinyl pyrrolidone, polyalkylene oxides, polyacrylates, caprolactams, polymethacrylates, polymethyl methacrylates, polyacrylamides, polymethacrylamides, polydimethylacrylamides, polyethylene glycol monomethacrylate, copolymers of acrylic acid and methyl acrylate, polyurethanes, polycarboxylates, polyvinyl acetates, polyesters, polyamides, polyamines, polyethyleneimines, maleic acid / (acrylate or methacrylate) copolymers, copolymers of methyl vinyl ether and maleic anhydride, copolymers of vinyl acetate and crotonic acid, copolymers of vinylpyrrolidone and vinyl acetate, copolymers of vinylpyrrolidone and caprolactam, vinylpyrrolidone / vinyl acetate copolymers, copolymers of anionic, cationic and amphoteric monomers, and combinations thereof.

[0114] The water-soluble polymers may also be selected from polymers derived from nature, including those of plant origin, examples of which include gum karaya, gum tragacanth, gum arabic, acetomorphan, konjac glucoside, gum acacia, gum dawa, whey protein isolate, and soy protein isolate; seed extracts, including guar gum, locust bean gum, quince seed, and psyllium seed; seaweed extracts such as carrageenan, alginates, and agar; fruit extracts (pectin); those of microbial origin, including xanthan gum, gellan gum, pullulan, hyaluronic acid, chondroitin sulfate, and dextran; and those of animal origin, including casein, pectin, keratin, keratin hydrolysates, sulfokeratin, albumin, collagen, gluten, glucagon, gluten, zein, and shellac.

[0115] Modified natural polymers can also be used as water-soluble polymers herein. Suitable modified natural polymers include, but are not limited to, cellulose derivatives such as hydroxypropyl methylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, methylcellulose, hydroxypropyl cellulose, ethylcellulose, carboxymethylcellulose, cellulose acetate phthalate, nitrocellulose and other cellulose ethers / esters; and guar gum derivatives such as hydroxypropyl guar gum.

[0116] The water-soluble polymer may include starch. As used herein, the term "starch" includes naturally occurring or modified starch. Typical natural sources of starch may include cereals, tubers, roots, beans, and fruits. More specific natural sources may include corn, peas, potatoes, bananas, barley, wheat, rice, sago, amaranth, cassava, arrowroot, canna, sorghum, and waxy or high-amylase varieties thereof. Natural starches can be modified by any modification method known in the art to form modified starches, including physically modified starches, such as sheared starches or heat-inhibited starches; chemically modified starches, such as those that have been cross-linked, acetylated and organically esterified, hydroxyethylated and hydroxypropylated, phosphorylated, and inorganically esterified, cationic, anionic, nonionic, amphoteric and zwitterionic derivatives thereof, and succinate and substituted succinate derivatives thereof; conversion products derived from any of the starches, including fluid starches or thin-boiling starches prepared by oxidation, enzymatic conversion, acid hydrolysis, heating, or acid dextrinization, heat-treated and / or sheared products can also be used herein; and pregelatinized starches as known in the art.

[0117] The water-soluble polymer may include polyvinyl alcohol, polyvinyl pyrrolidone, polyalkylene oxide, starch and starch derivatives, pullulan, gelatin, hydroxypropyl methylcellulose, methylcellulose and carboxymethylcellulose. In one example, the water-soluble polymer includes polyvinyl alcohol and / or hydroxypropyl methylcellulose.

[0118] The polyvinyl alcohol may be characterized by a degree of hydrolysis ranging from about 40% to about 100%, from about 50% to about 95%, from about 65% to about 92%, or from about 70% to about 90%. Commercially available polyvinyl alcohols include those available under the CELVOL trade name from Celanese Corporation (Texas, USA), including but not limited to CELVOL 523, CELVOL 530, CELVOL 540, CELVOL 518, CELVOL 513, CELVOL 508, CELVOL 504; and POVAL TM The flexible porous dissolvable solid sheet may comprise, based on the total weight of the sheet, from about 10% to about 25% or from about 15% to about 23% of a polyvinyl alcohol having a weight average molecular weight in the range of 80,000 to about 150,000 daltons and a degree of hydrolysis in the range of about 80% to about 90%.

[0119] In addition to the polyvinyl alcohol mentioned above, a single starch or a combination of starches can be used as a filler material in an amount that reduces the total required water-soluble polymer content, as long as this helps provide a solid sheet having the desired structure and physical / chemical properties as described herein. However, excessive starch can affect the solubility and structural integrity of the sheet. Therefore, it is desirable that the solid sheet contain no more than 20%, 0% to 10%, 0% to 5%, or 0% to 1% starch by weight of the solid sheet.

[0120] surfactants

[0121] In addition to the water-soluble polymers described above, the solid sheet also contains a surfactant. The surfactant can act as an emulsifier during the aeration process to generate a sufficient amount of stable bubbles for forming the desired OCF structure. In addition, the surfactant can act as an active ingredient for delivering the desired cleaning benefits.

[0122] The solid sheet can include a surfactant selected from the group consisting of anionic surfactants, nonionic surfactants, cationic surfactants, zwitterionic surfactants, amphoteric surfactants, polymeric surfactants, and any combination thereof. Depending on the desired application of this type of solid sheet and the desired consumer benefit to be achieved, different surfactants can be selected. One benefit is that the OCF structure of the solid sheet allows for the introduction of a high surfactant content while still providing rapid dissolution. Therefore, highly concentrated cleaning compositions can be formulated into solid sheets to provide new and excellent cleaning experiences to consumers.

[0123] As used herein, surfactants may include surfactants from the conventional sense (i.e., those that provide a foaming effect readily visible to the consumer) and emulsifiers (i.e., those that do not provide any foaming properties but are primarily used as processing aids to prepare a stable foam structure). Examples of emulsifiers useful as the surfactant component herein include mono- and diglycerides, fatty alcohols, polyglycerol esters, propylene glycol esters, sorbitan esters, and other emulsifiers known or otherwise commonly used to stabilize air interfaces.

[0124] The total amount of surfactant present in the solid sheet can be in a wide range of about 5% to about 95%, about 30% to about 90%, about 40% to about 80%, about 50% to about 70%, for example, 20%, 30%, 40%, 50%, 60%, 70%, 80%, or any range therebetween, based on the total weight of the solid sheet. Accordingly, the wet premix can comprise from about 1% to about 50% surfactant by weight of the wet premix, and in one example, from about 2% to about 40% surfactant by weight of the wet premix, and in one example, from about 10% to about 35% surfactant by weight of the wet premix, and in one example, from about 15% to about 30% surfactant by weight of the wet premix.

[0125] Non-limiting examples of anionic surfactants suitable for use herein include alkyl sulfates and alkyl ether sulfates, sulfated monoglycerides, sulfonated olefins, alkyl aryl sulfonates, primary or secondary alkane sulfonates, alkyl sulfosuccinates, acyl taurates, acyl isethionates, alkyl glyceryl ether sulfonates, sulfonated methyl esters, sulfonated fatty acids, alkyl phosphates, acyl glutamates, acyl sarcosinates, alkyl sulfoacetates, acylated peptides, alkyl ether carboxylates, acyl lactylates, anionic fluorosurfactants, sodium lauroyl glutamate, and combinations thereof.

[0126] One class of anionic surfactants particularly suitable for use in the practice of this invention includes C6-C 20 Linear alkylbenzene sulfonate (LAS) surfactants. LAS surfactants are well known in the art and can be readily obtained by sulfonating commercially available linear alkylbenzenes. Exemplary C 10 -C 20 Linear alkylbenzene sulfonates may include C 10 -C 20 Alkali metal salts, alkaline earth metal salts or ammonium salts of linear alkylbenzenesulfonic acid, and C 11 -C 18 or C 11 -C 14 Sodium, potassium, magnesium and / or ammonium salts of linear alkylbenzene sulfonic acid. 12 and / or C 14 Sodium or potassium salts of linear alkylbenzenesulfonic acid, i.e. sodium dodecylbenzenesulfonate and / or sodium tetradecylbenzenesulfonate.

[0127] LAS provides excellent cleaning benefits and is particularly suitable for use in laundry detergent applications. Surprisingly and unexpectedly found herein is that when the polyvinyl alcohol with higher weight-average molecular weight (for example, about 50,000 dalton to about 400,000 dalton, 60,000 dalton to about 300,000 dalton, about 70,000 dalton to about 200,000 dalton, about 80,000 dalton to about 150,000 dalton) is used as film former and carrier, LAS can be used as primary surfactant, i.e., be present in solid sheet with an amount exceeding 50% by the weight of total surfactant content, without adversely affecting the film-forming properties and the stability of overall composition. Accordingly, in a particular example, LAS is used as the primary surfactant in solid sheet. When present, the amount of LAS in solid sheet can be in the range of about 10% to about 70%, about 20% to about 65%, about 40% to about 60% by the gross weight of solid sheet.

[0128] Another class of anionic surfactants suitable for use in the practice of this invention includes sodium trideceth sulfate (STS), which has a weight average degree of alkoxylation ranging from about 0.5 to about 5, from about 0.8 to about 4, from about 1 to about 3, or from about 1.5 to about 2.5. Trideceth is a 13-carbon branched alkoxylated hydrocarbon, which, in one example, contains an average of at least one methyl branch per molecule. The STS used in the present invention may include ST(eOxPOy)S, where eOx refers to repeating ethylene oxide units having a repeat number x ranging from 0 to 5, 1 to 4, or 1 to 3, and pOy refers to repeating propylene oxide units having a repeat number y ranging from 0 to 5, 0 to 4, or 0 to 2. It will be appreciated that a material such as ST2S having a weight average degree of ethoxylation of about 2 may, for example, contain significant amounts of molecules having no ethoxylate, 1 mole ethoxylate, 3 moles ethoxylate, etc., while the distribution of ethoxylation may be broad, narrow, or trapped, still resulting in an overall weight average degree of ethoxylation of about 2. STS is particularly well suited for personal cleansing applications, and it has been surprisingly and unexpectedly discovered herein that when polyvinyl alcohol having a relatively high weight average molecular weight (e.g., about 50,000 Daltons to about 400,000 Daltons, about 60,000 Daltons to about 300,000 Daltons, about 70,000 Daltons to about 200,000 Daltons, about 80,000 Daltons to about 150,000 Daltons) is used as the film former and carrier, STS can be used as the primary surfactant, i.e., present in the solid sheet in an amount exceeding 50% by weight of the total surfactant content, without adversely affecting the film forming properties and stability of the overall composition. Accordingly, in one particular example herein, STS is used as the primary surfactant in the solid sheet. When present, the amount of STS in the solid sheet can range from about 10% to about 70%, from about 20% to about 65%, or from about 40% to about 60%, based on the total weight of the solid sheet.

[0129] Another class of anionic surfactants suitable for practice includes alkyl sulfates. These materials have the corresponding formula ROSO3M, where R is an alkyl or alkenyl group of about 6 to about 20 carbon atoms, x is 1 to 10, and M is a water-soluble cation such as ammonium, sodium, potassium, and triethanolamine. R can have from about 6 to about 18, from about 8 to about 16, or from about 10 to about 14 carbon atoms. Previously, due to the unalkoxylated C6-C 20Linear or branched alkyl sulfates (AS) are considered to be preferred surfactants in soluble solid sheets, especially as the primary surfactant therein, due to their compatibility with low molecular weight polyvinyl alcohols (e.g., those having a weight average molecular weight of not more than 50,000 Daltons) in terms of film-forming properties and storage stability. However, it was surprisingly and unexpectedly discovered that when polyvinyl alcohols having higher weight average molecular weights (e.g., about 50,000 Daltons to about 400,000 Daltons, about 60,000 Daltons to about 300,000 Daltons, about 70,000 Daltons to about 200,000 Daltons, about 80,000 Daltons to about 150,000 Daltons) are used as film-forming agents and carriers, other surfactants (such as LAS and / or STS) can be used as the primary surfactant in the solid sheet without adversely affecting the film-forming properties and stability of the overall composition. Thus, it is desirable to provide a solid sheet having no greater than about 20%, 0% to about 10%, 0% to about 5%, 0% to about 1% AS by weight of the solid sheet.

[0130] Another class of anionic surfactants includes C6-C 20 Linear or branched alkyl alkoxy sulfates (AAS). In this category, the corresponding formula RO(C2H4O) can be used. x A linear or branched alkyl ethoxy sulfate (AES) of SO3M, wherein R is an alkyl or alkenyl group of about 6 to about 20 carbon atoms, x is 1 to 10, and M is a water-soluble cation such as ammonium, sodium, potassium, and triethanolamine. R may have from about 6 to about 18, from about 8 to about 16, or from about 10 to about 14 carbon atoms.

[0131] The nonionic surfactant that can be included in the solid sheet can be any conventional nonionic surfactant, including but not limited to: alkyl alkoxylated alcohols, alkyl alkoxylated phenols, alkyl polysaccharides (especially alkyl glucosides and alkyl polyglucosides), polyhydroxy fatty acid amides, alkoxylated fatty acid esters, sucrose esters, sorbitan esters and alkoxylated derivatives of sorbitan esters, amine oxides, etc. The nonionic surfactant can include a nonionic surfactant having the formula R 1 (OC2H4) n Those of OH, where R 1 C8-C 18 An alkyl group or an alkylphenyl group, and n is from about 1 to about 80. For example, a C8-C8 having a weight average degree of ethoxylation of from about 1 to about 20, from about 5 to about 15, from about 7 to about 10, or a C8-C8 having a weight average degree of ethoxylation of from about 1 to about 20, from about 5 to about 15, from about 7 to about 10, can be used. 18 Alkyl ethoxylated alcohols, such as those available from Commercially available Nonionic surfactants. Other non-limiting examples of nonionic surfactants that can be used herein include: C6-C 12Alkylphenol alkoxylates, wherein the alkoxylate units may be ethyleneoxy units, propyleneoxy units, or mixtures thereof; C 12 -C 18 Alcohol and C6-C 12 Condensates of alkylphenols with ethylene oxide / propylene oxide block polymers, such as BASF's C 14 -C 22 Medium-chain branched alcohol (BA); C 14 -C 22 Mid-chain branched alkyl alkoxylate, BAE x , wherein x is 1 to 30; alkyl polysaccharides, specifically alkyl polyglycosides; polyhydroxy fatty acid amides; and ether-terminated poly (alkoxylated) alcohol surfactants. Suitable nonionic surfactants also include those sold by BASF under the trade name Those that are sold.

[0132] An example of a nonionic surfactant is a C6-C8 surfactant having a weight average degree of alkoxylation in the range of 5 to 15. 20 Linear or branched alkyl alkoxylated alcohols (AA), C 12 -C 14 Linear ethoxylated alcohols. If present, the amount of AA-type nonionic surfactant in the solid sheet may range from about 2% to about 40%, from about 5% to about 30%, or from about 8% to about 12%, based on the total weight of the solid sheet.

[0133] Suitable amphoteric surfactants for use in solid sheets include those broadly described as derivatives of aliphatic secondary and tertiary amines, in which the aliphatic radical may be straight or branched chain, and in which one of the aliphatic substituents contains from about 8 to about 18 carbon atoms and one contains an anionic water-solubilizing group such as a carboxyl, sulfonate, sulfate, phosphate, or phosphonate. Examples of compounds falling within this definition are sodium 3-dodecylaminopropionate, sodium 3-dodecylaminopropanesulfonate, sodium lauryl sarcosinate, N-alkyltaurines (such as those prepared by the reaction of dodecylamine with sodium isethionate), and N-higher alkyl aspartic acids.

[0134] Suitable zwitterionic surfactants include those broadly described as derivatives of aliphatic quaternary ammonium, phosphonium, and sulfonium compounds, wherein the aliphatic radical may be straight or branched chain, and wherein one of the aliphatic substituents contains from about 8 to about 18 carbon atoms and one aliphatic substituent contains an anionic group such as carboxyl, sulfonate, sulfate, phosphate, or phosphonate. Such suitable zwitterionic surfactants can be represented by the formula:

[0135]

[0137] Cationic surfactants are also useful herein, especially in fabric softener and hair conditioner products. When used to prepare products containing cationic surfactants as the primary surfactant, such cationic surfactants may be present in an amount of from about 2% to about 30%, from about 3% to about 20%, or from about 5% to about 15%, based on the total weight of the solid sheet.

[0138] Cationic surfactants can include DEQA compounds, which include descriptions of diamide actives and actives having mixed amide and ester bonds. DEQA compounds are typically prepared by the reaction of alkanolamines such as MDEA (methyldiethanolamine) and TEA (triethanolamine) with fatty acids. Some materials commonly generated by such reactions include N,N-bis(acyloxyethyl)-N,N-dimethylammonium chloride or N,N-bis(acyloxyethyl)-N,N-methylhydroxyethylammonium methyl sulfate, where the acyl groups are derived from tallow, unsaturated and polyunsaturated fatty acids.

[0141] plasticizers

[0142] The flexible porous dissolvable solid sheet may also include a plasticizer in an amount ranging from about 0.1% to about 25%, about 0.5% to about 20%, about 1% to about 15%, or 2% to 12%, based on the total weight of the solid sheet. Accordingly, the wet premix used to form such a solid sheet may include about 0.02% to about 20% plasticizer by weight of the wet premix, and in one example, about 0.1% to about 10% plasticizer by weight of the wet premix, and in one example, about 0.5% to about 5% plasticizer by weight of the wet premix.

[0143] Suitable plasticizers for use herein include, for example, polyols, copolyols, polycarboxylic acids, polyesters, dimethicone copolyols, and the like.

[0148] Examples of plasticizers include glycerin, ethylene glycol, polyethylene glycol, propylene glycol, or mixtures thereof.

[0149] Additional ingredients

[0150] In addition to the above-mentioned ingredients such as water-soluble polymers, surfactants, and plasticizers, the solid sheet may contain one or more additional ingredients, depending on its intended application. Such one or more additional ingredients may be selected from fabric care actives, dishwashing actives, hard surface cleaning actives, beauty and / or skin care actives, personal cleansing actives, hair care actives, oral care actives, feminine care actives, baby care actives, bittering agents, and any combination thereof. The solid sheet may contain a bittering agent.

[0151] The solid sheet may also contain other optional ingredients known for use or useful in compositions, provided that such optional materials are compatible with the selected essential materials described herein or do not unduly impair the performance of the product.

[0152] Non-limiting examples of examples of the types of products that can be formed from the solid sheet include laundry detergent products, fabric softener products, hand cleaning products, shampoo or other hair treatment products, body cleansing products, shave preparation products, dish cleaning products, personal care bases containing medications or other skin care actives, moisturizing products, sunscreen products, beauty or skin care products, deodorant products, oral care products, feminine cleansing products, baby care products, fragrance-containing products, and the like.

[0153] Granular Material. The solid article may include a granular material. The granular material may comprise one or more at least partially water-insoluble particles comprising a first component, preferably an active component, and a second component, preferably an inactive component. The granular material may be within a single sheet, sandwiched between multiple sheets, or a combination thereof.

[0154] It has been unexpectedly discovered that some active agents may be coupled to other components and / or include other components, such as inactive components, which may contribute significantly to the residues seen on fabrics after washing. The present disclosure focuses on particulate materials that may be included in a solid article that may include one or more particles that are at least partially insoluble in water.

[0155] The particles or particle clusters can be distributed in pockets, which are distributed in layers, wherein such pockets can form between layers; the contact network and porosity within each particle cluster are governed by the physics of conventional particle packing, but within the layer the clusters are substantially expanded. The particles or particle clusters can be relatively uniformly distributed throughout the structure, with substantially no localized particle clustering; the filler is substantially expanded on the scale of a single particle, with less inter-particle contact and greater inter-particle porosity. Without wishing to be bound by theory, it is believed that a water-soluble dissolvable article comprising a layer containing elements and particles, wherein a viscous surfactant such as AES is separated into particles having an expanded structure, can improve the dispersion and dissolution of the solid article by faster absorption of water into the expanded structure and by reducing contact between particles having the viscous surfactant.

[0156] The granular material may comprise at least one at least partially water-insoluble particle. Each particle may comprise a first component, preferably an active component, and a second component, preferably an inactive component. These second components, preferably inactive components, may be insoluble or partially soluble. The inactive components may comprise fillers, carriers, structurants, builders, cellulosic polymers, or mixtures thereof.

[0157] The active ingredient can be selected from surfactants, organic polymeric compounds, enzymes, enzyme stabilizers, bleach systems, whitening agents, colorants, chelating agents, suds suppressors, conditioners, humectants, perfumes, perfume microcapsules, alkaline systems, pH control systems, buffers, alkanolamines and mixtures thereof.

[0158] The particles or particle clusters may have a particle size distribution such that D100 is in the range of about 1300 μm to about 20 μm, or about 1200 μm to about 50 μm, or about 1100 μm to about 100 μm, or about 1000 μm to about 200 μm, or about 900 μm to about 300 μm, or about 800 μm to about 400 μm, or about 700 μm to about 500 μm.

[0159] The particles or particle clusters may have a particle size distribution such that D50 is in the range of about 1800 μm to about 25 μm, or about 1700 μm to about 50 μm, or about 1600 μm to about 100 μm, or about 1500 μm to about 200 μm, or about 1400 μm to about 300 μm, or about 1300 μm to about 400 μm, or about 1200 μm to about 500 μm, or about 1100 μm to about 600 μm, or about 1000 μm to about 700 μm, or about 900 μm to about 800 μm.

[0160] Inactive ingredients

[0161] As previously mentioned, an inactive ingredient is a component or substance present in a formulation or product that does not constitute the primary active ingredient responsible for producing the intended functional effect. Inactive ingredients can provide a variety of other functions and can generally be classified according to these other functions. However, it should be understood that inactive ingredients can provide more than one function and some overlap is expected. Therefore, the following categories should not be interpreted too rigidly; many examples given for each category can reasonably be classified into other categories. However, attempts have been made to classify many examples of inactive ingredients by their primary function as fillers, carriers, structurants, or builders.

[0162] filler

[0163] Generally, filler is a kind of inactive component, is mainly used for increasing the bulk volume and the volume of detergent formulations.Filler, such as soluble salt (such as sodium sulfate, sodium chloride, sodium carbonate) helps the physical structure of detergent products, and does not actively participate in the cleaning process.They are used to optimize the form and the economic benefit of the product.These fillers are used for main structure or economic purpose, help the overall physical integrity of detergent products and help cost-effective manufacturing.Although fillers do not actively participate in the cleaning process, they are most important in optimizing the physical characteristics of detergents such as its outward appearance, texture and processing characteristics.Due to the solubility of sodium sulfate, sodium chloride and sodium carbonate in water and the compatibility with detergent formulations, they can be used as fillers.It should be understood that other examples of suitable fillers can be determined and used based on these standards.

[0164] carrier

[0165] Carriers can serve as a medium for uniform distribution and dispersion of active ingredients, facilitating their effective delivery during use. Carriers can help optimize the solubility and dispersibility of detergents in washing. Examples of carriers include inorganic salts, clays, starches, cyclodextrins, and their derivatives and / or combinations thereof. Examples of inorganic salts include, but are not limited to, magnesium carbonate, calcium carbonate, potassium carbonate, their derivatives and / or combinations thereof. Examples of clays include, but are not limited to, kaolin, bentonite, montmorillonite, illite, their derivatives and / or combinations thereof. Examples of cyclodextrins include, but are not limited to, α-cyclodextrin, β-cyclodextrin, and γ-cyclodextrin, their derivatives and / or combinations thereof.

[0166] Structuring agent

[0167] Structuring agents or structurants are components that impart a specific physical structure or form to solid laundry detergents. They contribute to the overall stability and consistency of the product. Structuring agents play a role in shaping the detergent into a desired form, such as a tablet or bar, and help maintain its structural integrity during storage and use. While fillers can also contribute to structure, structuring agents are particularly focused on shaping the detergent product.

[0168] The example of structurant includes silicate, including but not limited to sodium silicate.

[0169] detergent

[0170] A detergent builder is a component of a formulation that primarily assists in water softening, ion exchange, or complexation, thereby improving the overall cleaning efficiency of the product. They are not the primary active agents responsible for the intended functional effect of a detergent (usually cleaning).

[0171] Suitable builders include aluminosilicates (e.g., zeolite builders such as zeolite A, zeolite P, and zeolite MAP), silicates, phosphates such as polyphosphates (e.g., sodium tripolyphosphate), especially sodium salts thereof; carbonates, bicarbonates, sesquicarbonates, and carbonate minerals other than sodium carbonate or sodium sesquicarbonate; organic monocarboxylates, dicarboxylates, tricarboxylates, and tetracarboxylates, especially water-soluble non-surfactant carboxylates in the form of acid, sodium, potassium, or alkanolammonium salts, and oligomeric or water-soluble low molecular weight polymer carboxylates, including aliphatic and aromatic types; and phytic acid.

Active ingredients play different roles and can be broadly categorized based on their different functions. It is important to recognize that active ingredients can provide more than one function and that some overlap is expected. Therefore, the subsequent categories should not be interpreted too rigidly; many of the examples given for each category could reasonably be classified into other categories. However, attempts have been made to categorize many examples of active ingredients by their primary function. The following list summarizes the types of active ingredients, including surfactants, enzymes, polymeric dispersants, soil release polymers, amines, bleaches, bleach catalysts, brighteners, fabric softeners, encapsulating agents, fragrances, dye transfer inhibitors, chelating agents, foam suppressants, foam boosters, conditioners, fabric enhancers, pearlescent agents, sanitizing and malodorizing agents, and buffer systems.

[0249] Example

[0250] The following examples are presented to provide those of ordinary skill in the art with a complete disclosure and description of how to implement the methods, how to prepare and how to use the compositions and compounds disclosed and claimed herein. Efforts have been made to ensure accuracy with respect to numbers (e.g., amounts, temperatures, etc.), but some errors and deviations should be taken into account. The purpose of the following examples is not to limit the scope of the various embodiments, but rather to provide examples that illustrate specific embodiments.

[0251] Example 1

[0252] The purpose of this example is to illustrate the preparation of four unit dose preparations (Compositions 1 to 4). Compositions 1 and 2 contain granules that were prepared in a drum batch process to produce mixed granules (hereinafter referred to as "Production Route 1"). Compositions 3 and 4 contain granules that were prepared in a fluidized bed process to produce layered granules ("Production Route 2").

[0253] Various components were used in various compositions, as detailed in Table 1. Generally speaking, in compositions 1 to 4, a nonwoven web (hereinafter referred to as BW VT33 web) was used; a granular laundry detergent composition comprising a surfactant, a chelating agent, a polymeric builder, and a carbonate (hereinafter referred to as PolyAgg HT33) was used; a suds suppressor was used; an amylase was used; a protease was used; a processing aid, minor ingredients, and a fragrance were used. The specific amounts of each component and the enzyme activity of the final product are listed in Table 1. Material additions are shown as active material levels in the final product (FP).

[0254]

[0255] Production Route 1, a drum batch method for producing blended granules, involves mixing and homogenizing the various solid components to produce a uniform and consistent granular product. In this method, a large cylindrical drum or mixer is used. Dry raw materials are weighed and loaded into the drum. The drum is then rotated using a variable speed and tilt mechanism to ensure thorough mixing. During rotation, liquid components are sprayed onto the material to promote adhesion. This controlled stirring and blending process continues until the desired level of uniformity is achieved. Once the mixture is homogeneous, it is discharged from the drum and prepared for testing as described in Example 2.

[0256] Production path 2, fluidized bed method, uses fluidized bed reactor or dryer. Dry raw materials are introduced into the fluidized bed. Then heated air or gas is blown into the chamber from below, so that these materials become suspended and behave like fluid. Additional liquid materials are then introduced through nozzles above the fluidized bed. When these additional liquid materials are sprayed or poured onto the fluidized core, they adhere to the original raw materials to form different layers. Control of gas flow and manipulation of process parameters (such as temperature, airflow and spray rate) can determine the thickness and composition of each layer. This process continues until the desired layered granular structure is obtained. Once completed, take out the product and prepare for testing as described in Example 2.

[0257] Example 2

[0258] The purpose of this example is to illustrate the effect of the enzyme pellet production route on fabric residue. Three external replicates were performed for each composition. 1000 ml of tap water was metered into each tergotometer pot and cooled to 10°C or heated to 25°C. 1.22 g of the test composition was then added and a timer started. After 20 minutes of dissolution, the entire wash solution was removed from each tergotometer pot and the mixture was concentrated using a vacuum pump, a 3-piece 9 cm diameter Büchner funnel, and a 1 / 4" (1 / 4-inch) sidearm. The flask was filtered through black fabric. Table 2 summarizes the materials used.

[0259]

[0260]

[0261] At the beginning of each test, the black fabric was weighed using a balance so that the residual weight could be determined gravimetrically. The fabric was dried overnight at room temperature and then reweighed using Analyze the CIELAB color space of any residue deposited on the fabric.

[0262] Lab color space (CIELAB color space): Also known as L*a*b*, this is a color space defined by the International Commission on Illumination (CIE) in 1976. It represents color as three values: L* represents perceived lightness, and a* and b* represent the four unique colors of human vision: red, green, blue, and yellow. L* can range from 0 (black) to 100 (white); a* specifies the red-green color and can range from negative (green) to positive (red); and b* specifies the yellow-blue color and can range from negative (blue) to positive (yellow). The CIELAB color space is device-independent, meaning it is not dependent on any particular device or display technology. Therefore, it is a good choice for applications that require accurate color representation on a variety of devices.

[0263] The color difference between two colors can be calculated by measuring the L*a*b* values for each color. As shown in the following formula, the ΔE*ab value is a measure of the perceived color difference between the two colors. The higher the ΔE*ab value, the greater the perceived color difference.

[0264] ΔE*ab=√((ΔL*) 2 +(Δa*) 2 +(Δb*) 2 )

[0265] where ΔL*, Δa*, and Δb* are the differences in L*, a*, and b* values between the two colors.

[0266] ΔL*=L 经洗涤-L 初始

[0267] Δa*=a 经洗涤 -a 初始

[0268] Δb*=b 经洗涤 -b 初始

[0269] refer to Figure 5A L*, a*, and b* measurements are performed by analyzing a test fabric 1 containing one or more residue portions 2. The measurements are performed over the entire area enclosed by a perimeter 3 surrounding all of the one or more residue portions 2 on the fabric 1. The perimeter 3 is a circle with a radius of approximately 450 mm.

[0273]

[0274] These examples demonstrate the efficacy of fluidized bed layered granules within laundry detergent powder / web compositions, which produced less residue when tested at the same weight (Composition 3) compared to a drum batch process derived "mixed" granules (Composition 2), and when tested at the same active enzyme (Composition 4) compared to a drum batch process derived "mixed" granules (Composition 2).

[0275] Example 3

[0276] The purpose of this example is to show the residue left by various insoluble fillers (inactive ingredients) of various particle sizes on black cotton and polyester fabrics. The insoluble fillers included zeolite with a dry particle size of 4 μm, precipitated calcium carbonate with a dry particle size of 7 μm, magnesium carbonate (MgCO3) with a dry particle size of 15 μm, microcrystalline cellulose with a dry particle size of 20 μm, and microcrystalline cellulose with a dry particle size of 50 μm. In each test, 0.04 g of each filler was used per 800 ml of 6 gpg water. A vacuum pump, a 3-piece 9 cm diameter Büchner funnel and a side arm were used. The solution was filtered through a black fabric. Three replicates were performed for each material.

[0277] Figure 12A and Figure 13A Shown are photographs of three replicates of technical black cotton fabric and consumer black polyester fabric, respectively, after exposure to dry zeolite having a particle size of 4 μm.

[0278] Figure 12B and Figure 13BShown are photographs of three replicates of technical black cotton fabric and consumer black polyester fabric, respectively, after exposure to precipitated calcium carbonate having a dry particle size of 7 μm.

[0279] Figure 12C and Figure 13C Shown are photographs of three replicates of technical black cotton fabric and consumer black polyester fabric, respectively, after exposure to magnesium carbonate (MgCO3) having a dry particle size of 15 μm.

[0280] Figure 12D and Figure 13D Shown are photographs of three replicates each of technical black cotton fabric and consumer black polyester fabric after exposure to microcrystalline cellulose having a dry particle size of 20 μm.

[0281] Figure 12E and Figure 13E Shown are photographs of three replicates each of technical black cotton fabric and consumer black polyester fabric after exposure to microcrystalline cellulose having a dry particle size of 50 μm.

[0282] Based on visual inspection of these graphs, polyester fabric exhibited more residue than the cotton technical test fabric. This indicates that its smaller pore size traps insoluble particles. Insoluble particles 4 μm or smaller were shown to leave no visible residue on cotton or polyester fabrics. Polyester exhibited visible residue at particle sizes greater than approximately 7 μm. Cotton exhibited visible residue at particle sizes greater than approximately 20 μm.

[0283] Example 4

[0284] The purpose of this example is to demonstrate the residue left on black cotton and polyester fabrics by various granular formulations as shown below. Four powder detergent compositions (Compositions 1 to 4) were prepared and tested as detailed below.

[0292] II. Testing Procedure

[0293]

[0294] Analysis of residues on fabrics

[0295] The following procedure was used to determine the effect of the enzyme granule production approach on fabric residue. Three external replicates were performed for each test product. 1000 ml of tap water was metered into each tergotometer jar and cooled to 10°C or heated to 25°C. 0.75 to 0.88 g of product was then added and a timer started. After 20 minutes of dissolution, the entire wash solution was removed from each tergotometer jar and filtered through black fabric. A vacuum pump, a 3-piece 9 cm diameter Buckner funnel, and a pyrex flask with a side arm were used.

[0296] At the beginning of the test, the black fabric is weighed using a balance so that the residue weight can be determined gravimetrically. The fabric is dried overnight at room temperature and then reweighed and analyzed for L, a, b on the Digi-eye. L, a, b measurements are taken over the entire black fabric residue circle with a radius of 450 mm - see Figure 14 .

[0297] The results below show the measured levels of residue per leg by weight (g) and by color (ΔE):

[0298] ΔE=SQRT(ΔL×ΔL+Δa×Δa+Δb×Δb)

[0299] ΔL = L washed - L initial

[0306] *The residue weight used for this data point is the result of only two replicates. See the image on page 5, which highlights the blue product contamination. Therefore, this replicate was removed from the weight calculation. The image is still included to demonstrate the similar visual residue profiles of the replicates.

[0307] Figure 15A and Figure 16A Each shows a photograph of three replicates of technical black cotton fabric after exposure to Composition 1 at 10°C and 25°C, respectively.

[0309] Figure 15C and Figure 16C Each shows a photograph of three replicates of technical black cotton fabric at 10° C. and 25° C., respectively, after exposure to Composition 3. Notably, the third picture exhibits blue product contamination affecting the residue weight of this replicate.

[0310] Figure 15D and Figure 16D Each shows a photograph of three replicates of technical black cotton fabric after exposure to composition 4, at 10°C and 25°C, respectively.

[0311] These examples demonstrate the efficacy of fluidized bed layered granules within laundry detergent powder / web compositions, which produced less residue when tested at the same weight (Composition 3) compared to a drum batch process derived "mixed" granules (Composition 2), and when tested at the same active enzyme (Composition 4) compared to a drum batch process derived "mixed" granules (Composition 2).
