Description

[Technical Field]

[0001] Contains a mesh microstructure formed from a dry sodium fatty acid carboxylate compound. water soluble solid Body composition A low-moisture composition comprising a compound (SDC), a polyethylene glycol domain (PEGC), and a freshness-enhancing agent, which dissolves during normal use and delivers remarkable freshness to fabrics. [Background technology]

[0002] Freshness beads are added directly to the washing machine drum to supply freshness to the wash cycle. In the most basic design, the beads consist of a “primary” carrier (e.g., PEG, different molecular weights) and a freshness-enhancing agent (e.g., fragrance capsules, neat fragrance) to deliver the freshness effect. Suitable base compositions are disclosed, for example, in U.S. Patent No. 8,476,219 (B2). In more advanced designs, the beads also consist of one or more “secondary” carriers (often called fillers) dispersed in the primary carrier to fulfill one or more specific functions in the beads. For example, in one disclosure (U.S. Patent No. 9,347,022 (B1)), starch granules are added to the PEG in the beads to reduce the cost of the beads. In another disclosure (International Publication No. 2021 / 170759 (A1)), polymers, inorganic salts, clays, sugars, polysaccharides, glycerol, and fatty alcohols are added to facilitate processing and increase stability. In yet another example, the beads consist of a “primary” carrier comprising salts and sugars, sodium acetate trihydrate, and a block copolymer, as disclosed in U.S. Patent Nos. 11,008,535(B2), 11,220,657(B2), and 10,683,475(B2), respectively.

[0003] Formulating effective solid-soluble compositions presents considerable challenges. The compositions must be physically stable, preferably temperature and humidity resistant, and furthermore, they must be able to dissolve in solution, leaving little to no material residue, thereby performing the desired function. Solid-soluble compositions are well known in the art and are used in several roles, including detergents, oral and body medications, disinfectants, and cleaning compositions.

[0004] It has a mesh microstructure formed from dry sodium fatty acid carboxylate that can contain high concentrations of active substances. water soluble solid Body composition The product (SDC) is readily soluble in water during washing conditions, yet is temperature and humidity resistant, enabling supply chain stability. water soluble solid Body composition The ability to create the product (SDC) is remarkable. Low-moisture compositions containing both PEGC and SDC domains have been found to offer significant advantages over current freshness beads, including improved dissolution rate, sustainability, wider fragrance range, moisture control, broader sourcing opportunities, cost reduction, lighter weight for efficient e-commerce transport, and protection of unsuitable chemicals.

Such products may be used as pre-wash and post-wash treatments.

[0017] As used herein, "particles" typically means separate masses (or chunks) in a low-moisture composition, having a mass exceeding approximately 5 mg and a size exceeding 1 mm. Particles may have different shapes, including, but not limited to, hemispheres, spheres, plates, gummy bears, and cashews. Particles may have one or more layers.

[0018] When used herein, the "Solid Solubility Composition Mixture" (SDCM) is defined as the mixture before water removal (e.g., during the mixing or crystallization stage). water soluble solid Body composition Contains the components of the finished product. water soluble solid Body compositionTo produce the product, an intermediate solid-soluble composition mixture containing an aqueous phase with an aqueous carrier is first formed. The aqueous carrier may be distilled water, deionized water, or tap water. The aqueous carrier may be present in an amount of about 65% to 99.5% by weight, or about 65% to 90% by weight, or about 70% to 85% by weight, or about 75% by weight of the SDCM.

[0019] As used herein, “rheological solid composition” (RSC) describes the solid form of SDCM after crystallization (crystallization stage) before water removal to obtain SDC, where RSC contains more than approximately 65% ​​by weight of water, and the solid form is derived from a linked “structured” mesh (mesh microstructure) of fibrous crystalline particles from the crystallizing agent.

[0020] As used herein, "PEG" comprises polyethylene glycol (PEG) having a molecular weight of about 200 to about 50,000 daltons, most preferably about 6,000 to 10,000 daltons.

[0021] As used herein and as further described below, “freshness beneficial agent” includes materials added to a domain to impart a freshness effect to a fabric through washing. In some embodiments, the freshness beneficial agent may be a neat fragrance. In embodiments, the freshness beneficial agent may be an encapsulated fragrance (fragrance capsule). In embodiments, the freshness beneficial agent may be a mixture of fragrances and / or fragrance capsules.

[0022] As used herein, “crystallization temperature” is used to describe the temperature at which a crystallizing agent (or combination of crystallizing agents) is completely solubilized in SDCM, or, as used herein, to describe the temperature at which a crystallizing agent (or combination of crystallizing agents) exhibits any crystallization in SDCM.

[0023] As used herein, “dissolution temperature” is used to describe the temperature at which a low-water-content composition is completely solubilized in water under normal washing conditions.

[0024] As used herein, “stable temperature” is the temperature at which the SDC and / or PEGC domain material completely melts, such that the composition no longer exhibits a stable solid structure and can be considered a liquid or paste, and the low-moisture composition no longer functions as intended. The stable temperature is the lowest thermal transition temperature determined by a thermal stability test method. In embodiments of the present invention, the stable temperature may be greater than about 40°C, more preferably greater than about 50°C, more preferably greater than about 60°C, and most preferably greater than about 70°C, in order to ensure stability in the supply chain.

[0025] As used herein, “humidity stability” is the relative humidity at which a low-moisture composition spontaneously absorbs more than 5% by weight of its original mass in water from the ambient humidity at 25°C. Water absorption may occur in either the SDC domain and / or the PEGC domain. Absorption of small amounts of water when exposed to a humid environment allows for more sustainable packaging. Absorption of large amounts of water risks the composition softening or liquefying and no longer functioning as intended. In embodiments of the present invention, humidity stability may be greater than 70% RH, more preferably greater than 80% RH, more preferably greater than 90% RH, and most preferably greater than 95% RH. Those skilled in the art will understand the method of measuring a 5% weight increase using a dynamic vapor sorption (DVS) apparatus, which is further described in the humidity test method.

[0027] As used herein, “dissolves during normal use” means that a low-water-content composition dissolves completely or substantially during a cleaning cycle. Those skilled in the art will recognize that cleaning cycles have a wide range of conditions (e.g., cycle time, machine type, cleaning solution composition, temperature). A suitable composition dissolves completely or substantially under at least one of these conditions.

[0028] As used herein, the term "bio-based" material refers to renewable materials.

[0029] As used herein, the term “renewable material” refers to a material produced from a renewable material. As used herein, the term “renewable resource” refers to a resource produced by natural processes at a rate comparable to its consumption rate (e.g., within a 100-year timeframe). This resource may be replenished naturally or by agricultural technology. Non-limiting examples of renewable resources include plants (e.g., sugarcane, beets, maize, potatoes, citrus fruits, woody plants, lignocellulose, hemicellulose, and cellulose waste), animals, fish, bacteria, fungi, and forest products. These resources may be naturally occurring, hybridized, or genetically modified organisms. Natural resources such as crude oil, coal, natural gas, and peat, which take more than 100 years to form, are not considered renewable resources. Since at least a portion of the materials of the present invention are derived from renewable resources that can be decarbonized, the use of these materials can reduce the potential for global warming and fossil fuel consumption.

[0030] As used herein, the term “bio-based content” refers to the amount of carbon in a material derived from renewable resources, as a percentage of the weight (mass) of the total organic carbon in the material, determined using ASTM D6866-10, Method B.

[0031] The term "solid" refers to the state of the composition under the expected storage and use conditions for low-moisture compositions.

[0032] When used herein, articles such as "a" and "an" are understood to mean one or more of the claims or descriptions when used in the claims.

[0033] As used herein, the terms “include,” “includes,” and “including” are intended to be non-limiting.

[0034] Unless otherwise noted, all concentrations of components or compositions refer to the active portion of that component or composition, excluding impurities that may be present in the commercially available source of such components or compositions, such as residual solvents or by-products.

[0035] All percentages and ratios are calculated on a weight basis unless otherwise specified. All percentages and ratios are calculated based on the total composition unless otherwise specified.

[0036] It should be understood that all maximum numerical limits given throughout this specification include all lower numerical limits as if they were explicitly stated herein. All minimum numerical limits shown throughout this specification include all higher numerical limits as if they were explicitly stated herein. All numerical ranges given throughout this specification include all narrow numerical ranges that fall within such broad numerical ranges as if they were explicitly stated herein.

[0037] water soluble solid Body composition The composition (SDC) comprises fibrous linked crystals (Figures 1A and 1B) having sufficient crystalline fiber length and concentration to form a mesh microstructure. The mesh allows the SDC to be solid with a relatively small amount of material. The mesh also allows for the capture and protection of particles such as freshness beneficial agents, such as fragrance capsules (Figures 2A and 2B). In embodiments, the active material is discrete particles having a diameter of less than 100 μm, preferably less than 50 μm, and more preferably less than 25 μm. Furthermore, the considerable voids in the mesh microstructure also allow for the inclusion of liquid freshness beneficial agents, such as neat fragrances. In embodiments, up to about 15% by weight of neat fragrance, preferably 13% to 0.5% by weight, preferably 13% to 2% by weight, and most preferably 10% to 2% by weight, can be added. The voids also provide pathways for water to be incorporated into the microstructure during washing to accelerate dissolution compared to a completely solid composition.

[0038] Remarkably, it is possible to prepare SDCs with high dissolution rates, low water content, moisture resistance, and thermal stability. Sodium salts of long-chain fatty acids (i.e., sodium myristate (NaC14) to sodium stearate (NaC18)) can form fibrous crystals. It is generally understood that the crystal growth pattern resulting in fibrous crystallization reflects the hydrophilic (head group) and hydrophobic (hydrocarbon chain) balance of the NaC14-NaC18 molecules. As disclosed in this application, the crystallizers used have the same hydrophilic contribution but exhibit very different hydrophobicity due to the shorter hydrocarbon chain of the fatty acid sodium carboxylate used. In fact, the carbon chain is about half the length of those previously disclosed (U.S. Patent Application Publication 2021 / 0315783(A1)). Furthermore, those skilled in the art will recognize that many surfactants, such as alkyl sulfates, which have the same chain but different head groups, are susceptible to considerable moisture uptake and significant temperature-induced changes. The selected group of crystallizers in the present invention enables all of these useful properties.

[0039] Current water-soluble polymers (e.g., PEG only) limit the use of fragrance capsules as a fragrance enhancer delivery system. The encapsulated fragrance is delivered in an aqueous slurry, with the slurry limited to a maximum of 20-30% by weight of the encapsulated fragrance, and the total amount of encapsulated fragrance limited to approximately 1.2% by weight. Using encapsulated fragrances at concentrations exceeding these limits the solidification of the water-soluble carrier, thereby restricting fragrance delivery. As a result, consumers generally do not fully enjoy the desired amount of freshness due to the limitations on what they can add to their cleaning solutions. This invention addresses this issue. water soluble solid Body composition The composition can construct fragrance capsules of up to 18% by weight, resulting in approximately 15 times greater fragrance delivery compared to current water-soluble polymers. Such high delivery is at least partially enabled by the low water content of the composition, allowing users to experience a significant freshness upgrade compared to current commercially available fabric freshness beads (Figure 3).

[0040] The improved performance of the present invention's compositions compared to current freshness laundry beads is thought to be related to the dissolution rate of the composition's matrix. While not limited to theory, it is considered likely that if the composition dissolves later in the wash cycle, the encapsulated fragrance will deposit on the fabric throughout the wash (TTW), enhancing freshness performance. Current water-soluble polymers used in commercially available fabric freshness beads have a limited dissolution rate, set by the limited molecular weight (MW) range of polyethylene glycol (PEG) used as the dissolution matrix. As a result, single PEG beads must function under a certain range of machine and wash conditions, limiting their performance. In contrast, the dissolution rate of the present composition can be adjusted to suit a range of machine and wash conditions by adjusting the ratio of the composition components (e.g., sodium laurate (NaL) to sodium decanoate (NaD) ratio) (Figures 4A-4C). This allows for the creation of a wide range of compositions useful under many different wash conditions, where the SDC domains can release freshness beneficial agents at different times during the wash cycle.

[0041] The main commercially available fabric freshness bead manufacturing processes limit the selection of freshness beneficial agents. Alternatively, SDC domains can be processed and added to low-moisture compositions. PEG, used to form most currently commercially available beads, must be processed at temperatures between 70°C and 80°C, above the melting point of PEG. Preparing SDC domains at room temperature allows for a wider variety of freshness technologies. In practical processes, the melting point of PEG must be maintained for several hours, and some fragrance ingredients are highly volatile and evaporate during processing. Inclusion of fragrance oils for SDC is performed at around 25°C, opening up a wide range of neatly added fragrances. Furthermore, many fragrance capsule wall structures cease to function at higher process temperatures, releasing the encapsulated fragrances and rendering them inactive in low-moisture compositions. Processing fragrance capsules at lower temperatures allows for a wider range of capsules.

[0042] Controlling water migration in mixed bead compositions (e.g., low-water-content and high-water-content beads) is difficult with current water-soluble polymers because water migrates to the surface of the high-water-content beads. Since beads are often packaged in encapsulated packages to minimize moisture permeation to and from the package, moisture trapped on the surface of the high-water-content beads comes into contact with the surface of the low-water-content beads, leading to bead aggregation and product distribution problems. In contrast, water soluble solid Body composition The structure of the material prevents water movement and therefore allows the use of materials sensitive to water absorption (e.g., cationic polymers, bleaches).

[0043] As mentioned above, current bead formulations using PEG (and other structured materials) are prone to degradation when exposed to heat and / or humidity during transport. Therefore, special transport conditions and / or packaging are often required to mitigate such degradation. The SDC of the present invention contains a crystalline structure that is stable within a range of temperature and humidity conditions. The SDC domain exhibits %dm of less than 5% at 70% RH, more preferably less than 5% at 80% RH, and most preferably less than 5% at 90% RH, as determined by a humidity test method (Figure 5), and does not exhibit an intrinsic melt transition below 50°C, as determined by a thermal stability test method (Figure 6). As a result, no additional resources are required for refrigeration and plastic packaging during transport to prevent moisture migration. Including the SDC domain in a low-moisture composition allows for robust protection of freshness beneficial agents.

[0044] Finally, although I don't want to limit myself to theory, water soluble solid Body composition The high dissolution rate of the product is thought to be at least partially provided by the mesh microstructure. This is considered important because this porous structure provides the product with both "lightness" and the ability to dissolve rapidly compared to compressed tablets, which allows for easy delivery of the active substance during use. A single crystallizing agent (or in combination with other crystallizing agents) water soluble solid Body compositionIt is considered important to form fibers in the manufacturing process. Fiber formation allows for the retention of active substances without requiring compression that could break microencapsulation. water soluble solid Body composition Making finished products possible.

[0045] In the embodiment, the fibrous crystals may have a minimum length of 10 μm and a thickness of 2 μm, as determined by a fiber testing method. Non-limiting examples of particles are shown in Figures 7, 8, 9, and 10.

[0046] In the embodiment, the active substance may take the form of particles, which may be a) uniformly dispersed within a mesh microstructure, b) coated on the surface of a mesh microstructure, or c) some of the particles may be dispersed within the mesh microstructure and some of the particles may be coated on the surface of a mesh microstructure. In the embodiment, the active substance may be a) in the form of a soluble film on the upper surface of a mesh microstructure, b) in the form of a soluble film on the bottom surface of a mesh microstructure, or c) in the form of a soluble film on both the bottom and top surfaces of a mesh. The active substance may exist as a combination of a soluble film and particles.

[0047] Crystallizing agent The crystallizing agent is selected for its ability to impart different properties to the SDC domain. The crystallizing agent is selected from a small group of sodium fatty acid carboxylates having saturated chains and chain lengths in the range of C8-C12. Within this compositional range, using the preparation method described, such sodium fatty acid carboxylates provide a fibrous mesh microstructure, an ideal solubilization temperature for dissolution during preparation and use, and can be obtained by appropriate blending. water soluble solid Body composition The finished product's properties can be adjusted to suit various applications and conditions.

The crystallizing agent may be present in the solid soluble composition in amounts of about 50% to about 99% by weight, about 60% to about 95% by weight, and about 70% to about 90% by weight. The crystallizing agent may be present in the low moisture composition in amounts of about 5% to about 60% by weight, about 10% to about 50% by weight, and about 15% to about 40% by weight.

[0086] Dissolution test method All samples and procedures are maintained at room temperature (25±3°C) before testing and placed in a desiccant chamber (0%RH) for 24 hours or until a constant weight is reached.

[0087] All dissolution measurements are performed at a controlled temperature and a constant stirring rate. A 600 mL jacketed beaker (Cole-Palmer, catalog no. UX-03773-30, or equivalent) is mounted and cooled to the desired temperature by circulating water through the jacketed beaker using a water circulator (Fisherbrand Isotemp 4100, or equivalent) set to the desired temperature. The jacketed beaker is placed in the center of the stirring element of a VWR Multi-Position Stirrer (VWR North American, West Chester, PA, USA catalog no. 12621-046). 100 mL of deionized water (MODEL 18MΩ, or equivalent) and a stirring rod (VWR, Spinbar, catalog no. 58947-106, or equivalent) are added to a second 150 mL beaker (VWR North American, West Chester, PA, USA catalog no. 58948-138, or equivalent). Place the second beaker into the jacketed beaker. Add enough Millipore water to the jacketed beaker so that the water level in the jacketed beaker is higher than that in the second beaker, taking great care to prevent the water in the jacketed beaker from mixing with the water in the second beaker. Set the stirring rod speed to 200 RPM, sufficient to generate a gentle vortex. The temperature is set to reach 25°C or 37°C in the second beaker using the flow from the water circulator, and the relevant temperature is reported in the example. Before conducting the dissolution experiment, measure the temperature in the second beaker with a thermometer.

[0088] All samples were sealed in a desiccator prepared with a fresh desiccant (VWR, Desiccant-Anhydrous Indicating Drierite, stock number 23001, or equivalent) until a certain weight was reached. All test samples had a mass of less than 15 mg.

[0089] A single dissolution experiment is performed by removing a single sample from the desiccator. The sample is weighed within one minute of being removed from the desiccator, and its initial mass (M I) is measured. The sample is dropped into the second beaker while stirring the sample. The sample is dissolved for 1 minute. At the end of 1 minute, the sample is carefully removed from the deionized water. The sample is placed back in the desiccator until a constant final mass is reached. The percentage of mass loss of the sample in a single experiment is M L = 100 * (M I - M F ) / M I and is calculated as follows.

[0090] Nine additional dissolution experiments are performed by first replacing 100 ml of water with fresh deionized water, adding a new sample from the desiccator for each experiment, and repeating the dissolution experiment described in the previous paragraph.

[0091] The average percent mass loss (M A ) for the test is calculated as the average percent mass loss for the 10 experiments, and the average standard deviation of the mass loss (SD A ) is the standard deviation of the average percent mass loss for the 10 experiments.

[0092] This method returns three values: 1) the average mass of the sample (M S ), 2) the temperature (T) at which the sample is dissolved, and 3) the average percent mass loss (M A ). If the method is not run on a sample, the method returns "NM" for all values. The average percent mass loss (M A ) and the average standard deviation of the average percent mass loss (SD A ) are used to plot the dissolution curves shared in Figures 4A, 4B, and 4C. [[ID=3&6]]

[0093] Humidity Test Method Using the humidity test method, the amount of water vapor sorption occurring in the composition is determined between drying at 0% RH and drying at various RHs at 25°C. In this method, a 10 - 60 mg sample is weighed, and the mass changes associated with being conditioned in different environmental states are captured with a dynamic vapor sorption instrument. The resulting mass gain is expressed as the percent change in mass per dry sample mass recorded at 0% RH.

[0094] This method utilizes an SPSx Vapor Sorption Analyzer (ProUmid GmbH&Co.KG, Ulm, Germany) with a resolution of 1 μg, or an equivalent dynamic vapor sorbent (DVS) instrument capable of controlling relative humidity (%RH) to within ±3%, temperature to within ±2°C, and measuring mass with an accuracy of ±0.001 mg.

[0095] Disperse 10-60 mg of the raw material or composition sample uniformly in a tare-filled 1-inch diameter aluminum pan. Place the aluminum pan containing the dispersed raw material or composition sample into a DVS instrument, set the DVS instrument to 25°C and 0%RH, and record the mass at that point with an accuracy of 0.001 mg or better every 15 minutes. After the sample has been in the DVS for at least 12 hours under these conditions and a constant weight has been achieved, record the mass of the sample m d The amount is recorded with an accuracy of 0.01 mg or higher. Once this step is complete, the instrument is advanced in 10% RH increments up to 90% RH. The sample is held in DVS for a minimum of 12 hours at each step, and the mass of the sample is measured m until a constant weight is reached. n The data is recorded with an accuracy of 0.001 mg or higher at each stage.

[0096] For a specific sample, constant weight can be defined as the change in continuous mass weighing that does not differ by more than 0.004%. For a specific sample, the change in mass % (%dm) per unit of dry sample mass is defined as follows:

[0097]

number

[0098] The percentage change in mass per unit of dry sample mass is reported in units of 0.01%.

[0099] Humidity stability at 80%RH means that the humidity level fluctuates by 5% or less at 80%RH. Lack of humidity stability at 80%RH means that the humidity level fluctuates by more than 5% at 80%.

[0100] Thermal stability test method All samples and procedures are maintained at room temperature (25±3°C) and at a relative humidity of 40±10% for 24 hours prior to testing.

[0101] In the thermal stability test method, differential scanning calorimetry (DSC) is performed on a 20 mg ± 10 mg sample of the sample composition. Simple scanning is performed between 25°C and 90°C, and the temperature at which the maximum peak is observed is considered the stable temperature and reported in the nearest °C.

[0102] The sample is filled into the DSC dish. All measurements are performed using a high-volume stainless steel dish set (TA part number 900825.902). The dish, lid, and gasket are weighed using a Mettler Toledo MT5 analytical microbalance (or equivalent, Mettler Toledo, LLC., Columbus, OH) to determine the tare weight. The sample is filled into the dish to a target weight of 20 mg (+ / - 10 mg) according to the manufacturer's specifications, taking care to ensure that the sample is in contact with the bottom of the dish. The dish is then sealed with a TA High Volume Die Set (TA part number 901608.905). The final assembly is weighed to obtain the weight of the sample. The sample is filled into a TA Q Series DSC (TA Instruments, New Castle, DE) according to the manufacturer's instructions. The DSC procedure uses the following settings: 1) Equilibrate at 25°C; 2) Mark the end of cycle 1; 3) Increase temperature to 90.00°C at 1.00°C / min; 4) Mark the end of cycle 3; then 5) End method; press Run.

[0103] Moisture Test Method All samples and procedures are maintained at room temperature (25±3°C) and at a relative humidity of 40±10% for 24 hours prior to testing.

[0104] The moisture content test method is used to quantify the weight percentage of water in a composition. In this method, Karl Fischer (KF) titration is performed on each of three similar samples of the sample composition. The titration is performed using a volumetric KF titrator and a one-component solvent system. The sample is 0.3 ± 0.05 g in mass and is dissolved in the titration vessel for 2.5 minutes before titration. The average (arithmetic mean) moisture content of the three test specimen replicas is reported in units of 0.1 wt% of the sample composition.

[0105] To measure the water content of the sample, a Mettler Toledo V30S Volumetric KF Titrator is used. The instrument is equipped with Honeywell Fluka Hydraanal Solvent (catalog no. 34800-1L-US) for dissolving the sample, Honeywell Fluka Hydraanal Titrant-5 (catalog no. 34801-1L-US) for titrating the sample, and three drying tubes (titration bottle, solvent bottle, and waste bottle) filled with Honeywell Fluka Hydraanal Molecular sieve 3nm (catalog no. 34241-250g) to preserve the effectiveness of the anhydrous material.

The reported value is the weight percentage of water in the sample. Repeat this measurement three times for each sample and report the average of the three measurements.

[0116] Fiber testing methods The fiber testing method is: water soluble solid Body composition This is used to determine whether the product crystallizes under process conditions and whether it contains fibrous crystals. A simple definition of a fiber is "a thread or a thread-like structure or object." Fibers have a long length in only one direction (e.g., Figures 1A and 1B). This is different from other crystalline forms such as plates or lamellae that have long lengths in two or more directions (Figures 11A and 11B). Having DCS as a fiber. water soluble solid Body composition Only the finished product is within the scope of this invention. Those skilled in the art will know that if present in the same particles, water soluble solid Body composition Recognizes SDC domains from PEGC domains in the finished product.

[0117] A sample approximately 4 mm in diameter is placed on an SEM sample shuttle and stub (Quorum Technologies, AL200077B and E7406) having a pre-coated slit containing a 1:1 mixture of Scigen Tissue Plus optimal cutting temperature (OCT) compound (Scigen 4586) and colloidal graphite (agar scientific G303E). The placed sample is plunge-frozen in a liquid nitrogen slush bath. Next, the frozen sample is inserted into a Quorum PP 3010 Tcryo prep chamber (Quorum Technologies PP3010T) or equivalent and equilibrated to -120°C before freeze-fracturing. Freeze-fracturing is performed by cutting off the top of the vitreous sample using a cryogenic built-in knife in the cryoprep chamber. Additional sublimation is performed at -90°C for 5 minutes to remove any residual ice on the sample surface. The sample is further cooled to -150°C and sputter-coated with a Pt layer that is present in the cryo-prep chamber for 60 seconds to reduce static charge.

[0118] High-resolution imaging is performed using a Hitachi Ethos NX5000 FIB-SEM (Hitachi NX5000) or an equivalent device.

[0119] To determine the fibrous morphology of the sample, imaging is performed at a magnification of 20,000x. At this magnification, individual crystals of the crystallizing agent can be observed. The magnification may be slightly adjusted to a lower or higher value until individual crystals are observed. Those skilled in the art can evaluate the longest dimension of a representative crystal in the image. If this longest dimension is about 10 times or more the other orthogonal dimensions of the crystal, these crystals are considered fibers and are within the scope of the present invention. [Examples]

[0120] These examples have a mesh microstructure formed from a dry sodium fatty acid carboxylate formulation. water solublesolid Body composition This provides non-limiting examples of low-moisture compositions comprising a product (SDC) domain, a polyethylene glycol (PEGC) domain, and activators dispersed within these domains, such as freshness-enhancing agents that deliver exceptional freshness to fabrics.

[0121] The composition of the present invention represents particles containing an SDC domain that, when properly processed, forms a fibrous mesh that dissolves completely within a washing cycle, and which contains a crystallizing agent. The composition of the present invention also represents a PEGC domain that, when used in combination with the SDC domain, creates a unique low-moisture composition that is easy to process and provides distinctive aesthetic properties and improved freshness performance.

[0122] The freshness enhancer takes the form of a fragrance capsule and / or neat fragrance distributed to different domains. Example 1 demonstrates a particle consisting of two or more domains in which the SDC domain is small and completely encapsulated within a single PEGC domain (Figure 7). Example 2 demonstrates a particle consisting of two or more domains in which a single SDC domain is coated and completely encapsulated within the coating of the PEGC domain (Figure 8). Example 3 shows a particle consisting of two or more domains in which the particle has a PEGC domain core and SDC domains are scattered (Figure 9). Example 4 demonstrates a particle consisting of two or more domains in which the particle has one side containing a PEGC domain and one side containing an SDC domain (Figure 10). Example 5 proposes a low-moisture composition consisting of a physical mixture of two or more different types of particles and a freshness enhancer, wherein some of the particles are structured as described in Examples 1-4. Example 6 is neutralized and blended with PEGC water soluble solid Body composition This suggests specific blends of fatty acid materials used to manufacture the product, and compositions prepared from fragrance capsules having different wall structures.

[0123] The data in Tables 1 to 8 provides parameters related to the particles in the following manner. Preparation of SDC Domains - All weights listed in this part of the table correspond to the amounts added to prepare the solid soluble composition mixture (SDCM). "Freshness Agent % (Dry)" is the weight percentage of freshness agent remaining in the SDC after drying, assuming no residual water as determined by the moisture content test method. "Retardant CA %" is the weight percentage of NaC12 (slow dissolution) in a mixture of NaC12 and NaC10 and NaC8 (fast dissolution).

[0124] All SDC domains are prepared through three fabrication steps to ensure the formation of a fibrous mesh within the domain. 1. Mix the crystallizing agents completely in water to form SDCM, and optionally add the activator. 2. Formation - The composition from the mixing step is formed to the desired SDC size and dimensions by techniques including crystallization. 3. Drying - The amount of water is reduced to ensure desired performance, including solubility, hydration, and thermal stability, and an activator is optionally added.

[0125] Preparation of PEGC Domains - All weights listed in this part of the table correspond to the amounts of PEG and freshness agent added to prepare the PEGCs. Any water added to the domains by inclusion in the flavor capsule slurry is not removed and remains as part of the domains when combined to form a low-moisture composition.

[0126] Low Moisture Compositions - All weights listed in this section correspond to the amounts of SDC and PEGC combined to produce low moisture composition particles. For clarity, the percentages of the components of the low moisture composition are given as follows: "CA%" = crystallizer from SDC in the final low moisture composition, "Fragrance Capsules%" = fragrance capsules in the final low moisture composition, "Fragrance%" = neat fragrance in the low moisture composition, "PEG%" = PEG in the low moisture composition, and "Water%" = water in the low moisture composition, including water not removed from PEGC. Finally, "Average Mass" = the average mass of particles produced as described in each example of the low moisture composition.

[0127] The data in Tables 9-10 provide predictive particles composed solely of SDC and PEGC domains, the former having different blends of crystallizers and freshness enhancers, and the latter having PEG and freshness enhancers of different molecular weights.

[0128] The data in Tables 11-12 provide predictive low-moisture compositions containing a physical mixture of particles having SDC domains, PEGC domains, and freshness-enhancing agents. The "Amount of Fragrance Capsules During Washing" is the amount of fragrance capsules during washing to deliver the desired dry fabric feel effect to the consumer. The "Amount of Neat Capsules During Washing" is the amount of neat fragrance during washing to deliver the desired wet fabric feel effect to the consumer. The @ symbol displayed with the particles identifies the mass of the particles in the low-moisture composition. "Amount of Composition" is the total amount of all particles in the low-moisture composition, which the consumer adds to the washing solution.

[0129] The data in Table 13 provide a predictive low-moisture composition comprising an SDC domain prepared from a mixture of C8, C10, and C12 long-chain fatty acids that are neutralized to produce an SDC domain, and then combined with a PEGC domain and a flavor capsule having a different wall structure.

[0131] (Example 1) Example 1 demonstrates a particle composed of two or more domains in which the SDC domain is completely encapsulated within a single PEGC domain (Figure 7).

[0132] This embodiment demonstrates a composition that allows for the adjustment of the amount and distribution of different freshness beneficial agents using different domains within a single particle. In this non-limiting example, SDC domains are dispersed within a continuous domain of PEGC. This offers several advantages. First, SDC domains offer the opportunity to increase the amount of fragrance capsules in the particle (e.g., about 18% by weight) compared to a single PEGC domain (e.g., about 1.2% by weight). Second, these particles improve the aesthetics of the particles by maintaining the "smooth" appearance from PEGC. Third, such compositions offer advantages in manufacturing, as the flow properties of the "molten" composition are similar to those of the whole PEG composition, and these composite compositions offer the possibility of being prepared using existing commercially available equipment. Samples AA to AI are non-limiting examples of possible different domain compositions and weight ratios in the resulting particles that can be used as low-moisture compositions.

[0133] Preparation of the SDC domain Mixing - A 250 ml stainless steel beaker (Thermo Fisher Scientific, Waltham, MA) was placed on a hot plate (VWR, Radnor, PA, 7×7CER Hotplate, catalog number NO97042-690). Water (Milli-Q Academic) and a crystallizing agent were added to the beaker. A temperature probe was placed in the composition. An overhead mixer (IKA Works Inc, Wilmington, NC, model RW20 DMZ) and a mixing device including a 3-blade impeller design were assembled and adjusted. Made An impeller was placed in the material. The heater was set to 80°C and the impeller was set to rotate at 250 rpm, and the composition was heated to 80°C until all the crystallizing agent was solubilized and the composition became transparent. Then, MadeThe mixture was poured into a Max100 Mid Cup (Speed ​​Mixer), covered, and allowed to cool to 25°C. As specified in the table, the freshness enhancer was added by mixing the prepared mixture in a Speedmixer (Flack Tek.Inc, Landrum, SC, model DAC 150.1 FVZ-K) at 3000 rpm for 3 minutes.

[0134] Formation - The preparation was poured onto aluminum foil to a uniform thickness of approximately 1 mm. The preparation was then placed in a refrigerator (VWR Door Solid Lock F Refrigerator 115V, 76300-508, or equivalent) equilibrated at 4°C for 8 hours to allow the crystallizing agent to crystallize.

[0135] Drying - The compositions were dried for an additional 8 hours in a convection oven (Yamato, DKN400, or equivalent) set to 25°C, passing a steady flow of air through them. The final SDC was confirmed to have a moisture content of less than 10% by a moisture content test method. The domains were either in the shape of a mold or flat sheets were crushed into coarse pieces approximately 1 mm x 1 mm in size.

[0136] Preparation of PEGC domains Separately, a 250 ml stainless steel beaker (Thermo Fischer Scientific, Waltham, MA) was placed on a hot plate (VWR, Radnor, PA, 7×7CER Hotplate, catalog number NO97042-690). PEG (materials 8-11) was added to the beaker. An overhead mixer (IKA Works Inc, Wilmington, NC, model RW20 DMZ) and a mixing device including a 3-blade impeller design were assembled, and the impeller was placed in the composition. A temperature probe was also placed in the preparation. The impeller was set to rotate at 250 rpm. The preparation was heated to 100°C until the PEG was completely melted. As specified in the table, a freshness enhancer was added by placing the preparation in a Speedmixer (Flack Tek. Inc, Landrum, SC, model DAC 150.1 FVZ-K) at 3000 rpm for 3 minutes. Using this preparation, a low-moisture composition was prepared within 5 minutes of reaching the final temperature.

[0137] Preparation of low-moisture compositions A 60 ml Speed ​​Mixer cup and cap were weighed. The cap was removed, and the SDC domain was added to the cup. The cup was resealed with the cap and weighed again. The mass of the SDC domain in the preparation was the difference in weight.

[0138] A second 60 ml Speed ​​Mixer cup and cap were weighed. The cap was removed, and the freshness enhancer was added to the cup. The cup was resealed with the cap and weighed again, where the mass of the freshness enhancer in the preparation is the difference in weight. The cap was removed from the cup once more.

[0139] Less than 30 seconds later, PEGC was added to the cup, the cap was replaced, and the entire preparation was reweighed. The mass of PEGC in the preparation was the difference in weight. The cup was placed in a Speedmixer, started, and the preparation was mixed at 3000 RPM for 1 minute. Less than 30 seconds after mixing (and before crystallization), the preparation was transferred to a polymer mold patterned with 5 mm diameter hemispheres. The preparation was cooled at 25°C for at least 30 minutes. A diagram of the particle structure in this low-moisture composition is shown in Figure 7.

[0140] [Table 1]

[0141] [Table 2]

[0142] [Table 3]

[0143] (Example 2) Example 2 demonstrates particles consisting of two or more domains, each coated with a single SDC domain and completely encapsulated within a PEGC domain coating (Figure 8).

[0144] This embodiment demonstrates that the composition has particles having an SDC domain core and a PEGC coating. In this non-limiting example, a single SDC domain is encapsulated within a continuous domain of PEGC. This offers several advantages. These particles offer the opportunity to increase the amount of fragrance capsules in the SDC domain (e.g., about 18% by weight) compared to the amount in the SDC domain (e.g., about 1.3% by weight). The particles increase the freshness beneficial agent capacity by about 10 times. The SDC domain is also about 50-70% lower in density, making the particles (and the resulting low-moisture composition) more favorable for different commercial methods such as e-commerce, making them more sustainable with less carrier than required for unit freshness, and sustainably replacing petroleum-based PEG with a natural crystallizer. Furthermore, the use of the PEGC coating allows the particles to maintain the "smooth" or glossy appearance of the PEGC domain, which is appreciated by many consumers. Samples BA-BI are non-limiting examples of possible different domain compositions and weight ratios in the resulting particles.

[0145] Preparation of the SDC domain Mixing - A 250 ml stainless steel beaker (Thermo Fischer Scientific, Waltham, MA) was placed on a hot plate (VWR, Radnor, PA, 7×7 CER Hotplate, catalog number NO97042-690). Water (Milli-Q Academic) and crystallizer were added to the beaker. A temperature probe was placed in the composition. An overhead mixer (IKA Works Inc, Wilmington, NC, model RW20 DMZ) and a mixing device including a 3-blade impeller design were assembled, and the impeller was placed in the composition. The heater was set to 80°C and the impeller was set to rotate at 250 rpm, and the composition was heated to 80°C until all the crystallizer was solubilized and the composition became clear. The mixture was then poured into a Max100 Mid Cup (Speed ​​Mixer), covered, and allowed to cool to 25°C. As specified in the table, the freshness-enhancing agent was added by placing the preparation in a Speedmixer (Flack Tek.Inc, Landrum, SC, model DAC 150.1 FVZ-K) at 3000 rpm for 3 minutes.

[0146] Formed - The prepared material was transferred to a polymer mold patterned with hemispheres 5 mm in diameter. The mold was then placed in a refrigerator (VWR Door Solid Lock F Refrigerator 115V, 76300-508, or equivalent) equilibrated at 4°C for 8 hours to allow the crystallizing agent to crystallize.

[0147] Drying - The compositions were dried for an additional 8 hours in a convection oven (Yamato, DKN400, or equivalent) set to 25°C, passing a steady flow of air through them. The final SDC was confirmed to have a moisture content of less than 10% by a moisture content test method.

[0148] Preparation of PEGC domains Separately, a 250 ml stainless steel beaker (Thermo Fischer Scientific, Waltham, MA) was placed on a hot plate (VWR, Radnor, PA, 7×7 CER Hotplate, catalog number NO97042-690). PEG (materials 8-11) was added to the beaker. An overhead mixer (IKA Works Inc, Wilmington, NC, model RW20 DMZ) and a mixing device including a 3-blade impeller design were assembled, and the impeller was placed in the composition. A temperature probe was also placed in the preparation. The impeller was set to rotate at 250 rpm. The preparation was heated to 100°C until the PEG was completely melted. As specified in the table, a freshness enhancer was added by placing the preparation in a Speedmixer (Flack Tek. Inc, Landrum, SC, model DAC 150.1 FVZ-K) at 3000 rpm for 3 minutes. Using this preparation, a low-moisture composition was prepared within 5 minutes of reaching the final temperature.

[0149] Preparation of low-moisture compositions The weight of the weighing dish was measured. SDC was placed in the weighing dish, and the weight of the SDC was determined by the difference in mass. The SDC was immersed in PEGC molten material. Excess PEGC was wiped off the surface of the SDC. The preparation was placed in the weighing dish. The preparation was cooled at 25°C for at least 30 minutes. The weight of the weighing dish was measured, and the weight of the fragrance was determined by the difference in weight. A diagram of the particle structure in this low-moisture composition is shown in Figure 8.

[0150] [Table 4]

[0151] [Table 5]

[0152] [Table 6]

[0153] (Example 3) Example 3 shows a particle in which the particle has a PEGC domain core and is composed of two or more domains in which SDC domains are scattered (Figure 9).

[0154] Such particles offer, for example, the opportunity for particles to have significant amounts of PEGC and SDC domains, independent of the solubility characteristics of each domain. In non-limiting samples CA and CB, fragrance capsules are placed in SDC domains and released into a washing cycle at a rate consistent with the composition of the crystallizer blend, while neat fragrance is placed in PEGC domains and released into a washing cycle at a rate consistent with the molecular weight of PEG. The solubility percentage determined by the solubility test method is, here, independent of different domains, in contrast to the particles described in Example 1, for example. Furthermore, such forms are aesthetically advantageous to consumers, as the fixed domains exhibit different functions within the particles. Moreover, such forms are easily commercially prepared, for example, by passing warm PEGC domains through a "spray" of SDC domain particles that can adhere to the surface of the domains.

[0155] Preparation of the SDC domain Mixing - A 250 ml stainless steel beaker (Thermo Fischer Scientific, Waltham, MA) was placed on a hot plate (VWR, Radnor, PA, 7×7 CER Hotplate, catalog number NO97042-690). Water (Milli-Q Academic) and crystallizer were added to the beaker. A temperature probe was placed in the composition. An overhead mixer (IKA Works Inc, Wilmington, NC, model RW20 DMZ) and a mixing device including a 3-blade impeller design were assembled, and the impeller was placed in the composition. The heater was set to 80°C and the impeller was set to rotate at 250 rpm, and the composition was heated to 80°C until all the crystallizer was solubilized and the composition became clear. The mixture was then poured into a Max100 Mid Cup (Speed ​​Mixer), covered, and allowed to cool to 25°C. As specified in the table, the freshness-enhancing agent was added by placing the preparation in a Speedmixer (Flack Tek.Inc, Landrum, SC, model DAC 150.1 FVZ-K) at 3000 rpm for 3 minutes.

[0156] Formation - The preparation was poured onto aluminum foil to a uniform thickness of approximately 1 mm. The preparation was then placed in a refrigerator (VWR Door Solid Lock F Refrigerator 115V, 76300-508, or equivalent) equilibrated at 4°C for 8 hours to allow the crystallizing agent to crystallize.

[0157] Drying - The compositions were dried for a further 8 hours in a convection oven (Yamato, DKN400, or equivalent) set to 25°C, passing a steady flow of air through them. The final SDC was confirmed to have a moisture content of less than 10% by a moisture content test method. The flat sheets were crushed into coarse pieces approximately 1 mm x 1 mm in size.

[0158] Preparation of PEGC domains Separately, a 250 ml stainless steel beaker (Thermo Fischer Scientific, Waltham, MA) was placed on a hot plate (VWR, Radnor, PA, 7×7 CER Hotplate, catalog number NO97042-690). PEG (materials 8-11) was added to the beaker. An overhead mixer (IKA Works Inc, Wilmington, NC, model RW20 DMZ) and a mixing device including a 3-blade impeller design were assembled, and the impeller was placed in the composition. A temperature probe was also placed in the preparation. The impeller was set to rotate at 250 rpm. The preparation was heated to 100°C until the PEG was completely melted. As specified in the table, a freshness enhancer was added by placing the preparation in a Speedmixer (Flack Tek. Inc, Landrum, SC, model DAC 150.1 FVZ-K) at 3000 rpm for 3 minutes. Using this preparation, a low-moisture composition was prepared within 5 minutes of reaching the final temperature.

[0159] Preparation of low-moisture compositions A small amount of PEGC was placed in a weighing dish and weighed. A small amount of SDC was gently sprinkled onto the PEGC before significant crystallization occurred (within 30 seconds). Small-sized SDC domains adhered to the surface of the PEGC domains as the material crystallized. The preparation was cooled at 25°C for at least 30 minutes. The resulting particles were removed from the mold and reweighed to determine the aggregated amount of SDC. A diagram of the particle structure in this low-moisture composition is shown in Figure 9.

[0160] [Table 7]

[0161] (Example 4) Example 4 demonstrates a particle composed of two or more domains, with one side containing a PEGC domain and the other side containing an SDC domain (Figure 10).

[0162] Such particles also offer the opportunity to independently possess the solubility properties of each domain, for example, particles having significant amounts of PEGC and SDC domains. In the non-limiting examples of samples DA and DB, the fragrance capsule is placed in the SDC domain and released into a washing cycle at a rate consistent with the composition of the crystallizer blend, and the neat fragrance is placed in the PEGC domain and released into a washing cycle at a rate consistent with the molecular weight of PEG. The solubility percentage determined by the solubility test method is not dependent on different domains, here in contrast to the particles described in Example 1, for example. Furthermore, such a form does not impose limitations on the absolute amount of SDC and PEGC domains in the particles, compared to Example 3.

[0163] Preparation of the SDC domain Mixing - A 250 ml stainless steel beaker (Thermo Fisher Scientific, Waltham, MA) was placed on a hot plate (VWR, Radnor, PA, 7×7CER Hotplate, catalog number NO97042-690). Water (Milli-Q Academic) and a crystallizer were added to the beaker. A temperature probe was placed in the composition. An overhead mixer (IKA Works Inc, Wilmington, NC, model RW20 DMZ) and a mixing device including a 3-blade impeller design were assembled, and the impeller was placed in the preparation. The heater was set to 80°C and the impeller was set to rotate at 250 rpm, and the composition was heated to 80°C until all the crystallizer was solubilized and the composition became clear. The preparation was then poured into a Max100 Mid Cup (Speed ​​Mixer), covered, and allowed to cool to 25°C. As specified in the table, the freshness-enhancing agent was added by placing the preparation in a Speedmixer (Flack Tek.Inc, Landrum, SC, model DAC 150.1 FVZ-K) at 3000 rpm for 3 minutes.

[0164] Formed - The prepared material was transferred to a polymer mold patterned with hemispheres 5 mm in diameter. The mold was then placed in a refrigerator (VWR Door Solid Lock F Refrigerator 115V, 76300-508, or equivalent) equilibrated at 4°C for 8 hours to allow the crystallizing agent to crystallize.

[0165] Drying - The compositions were dried for a further 8 hours in a convection oven (Yamato, DKN400, or equivalent) set to 25°C, passing a steady flow of air through them. Once completely dry, the preparations were removed from the molds. The final SDC was confirmed to have a moisture content of less than 10% by a moisture content test method.

[0166] Preparation of PEGC domains Separately, a 250 ml stainless steel beaker (Thermo Fischer Scientific, Waltham, MA) was placed on a hot plate (VWR, Radnor, PA, 7×7 CER Hotplate, catalog number NO97042-690). PEG (materials 8-11) was added to the beaker. An overhead mixer (IKA Works Inc, Wilmington, NC, model RW20 DMZ) and a mixing device including a 3-blade impeller design were assembled, and the impeller was placed in the composition. A temperature probe was also placed in the preparation. The impeller was set to rotate at 250 rpm. The preparation was heated to 100°C until the PEG was completely melted. A freshness enhancer was added by placing the preparation in a Speedmixer (Flack Tek. Inc, Landrum, SC, model DAC 150.1 FVZ-K) at 3000 rpm for 3 minutes, as specified in the table. Using this preparation, a low-moisture composition was prepared within 5 minutes after reaching the final temperature. The preparation was transferred to a polymer mold patterned with hemispheres 5 mm in diameter.

[0167] Preparation of low-moisture compositions Within 30 seconds of placing the preparation in the mold, the domains of SDC were placed on the liquid PEGC, and the flat surface of SDC was placed on the flat surface of PEGC. The preparation was cooled at 25°C for at least 30 minutes. After complete cooling, the low-moisture composition was removed from the mold. The two domains were fixed, and the resulting particles were spherical as shown in Figure 10.

[0168] [Table 8]

[0169] (Example 5) Example 5 demonstrates a low-moisture composition comprising two or more different particles, the particles may contain a combination of SDC and PEGC domains as described in the previous examples, or they may contain only a single SDC and PEGC domain together with a freshness-enhancing agent. These non-limiting examples describe the latter. However, it is understood that physical blends of such particles for producing a low-moisture composition may also include the former.

[0170] Particle composition samples EA to EH (Tables 9 and 10) represent viable particle compositions containing a single SDC or PEGC domain. Samples EI to EQ (Tables 11 and 12) represent the low-moisture compositions of the present invention, composed of the particle compositions. The type and amount of particles in the low-moisture compositions are expressed as “composition dose,” or a typical amount used by a consumer in a single wash. When determining the dose, many considerations are important, including the amount of “fragrance capsules during washing” and the amount of “neat fragrance during washing” added by the dose. However, other factors, such as the selection of SDC or PEGC domain compositions, are also important in determining the level of freshness benefit. For example, consumers may prefer a very long-lasting freshness on dry fabric, which may require a dose of about 5 to 10 grams of fragrance capsules during washing, or they may prefer only an initial burst of freshness upon friction, which may require a dose of about 0.5 to 2 grams of fragrance capsules during washing. For example, consumers may prefer an extremely "instantaneous" freshness when removing a damp cloth from a detergent solution that may require approximately 5-10 grams of neat fragrance, or they may prefer a subtly pleasant lingering freshness when removing a damp cloth from a detergent solution that may require only approximately 1-2 grams of pure fragrance. These freshness profiles are further influenced by the dissolution rate of the domains containing the freshness-enhancing agents. Finally, the selection of particles constituting a low-moisture composition is also influenced by commercial considerations. Often, it is more commercially viable to produce two types of particles and physically mix them in different ratios, rather than a special process for each consumer, to allow the composition to reach all consumer preferences. This is often referred to as "delayed product differentiation." Some consumers may prefer doses containing a large amount of composition, around 50-100 grams, while some e-consumers or sustainability-conscious consumers may prefer a more concentrated, compact dose of around 10-20 grams. Ultimately, these examples offer a variety of freshness performances and commercial opportunities.

[0172] [Table 10] * Prepared from fragrance capsule slurry materials 5 and 6.

[0173] [Table 11]

[0174] [Table 12]

[0175] (Example 6) Example 6 is neutralized with an SDC composition and blended with a PEGC composition so that the SDC (e.g., Figures 4A, 4B, and 4C) and PEGC domains have different dissolution rate profiles. water soluble solid Body composition We propose that compositions prepared from specific blends of fatty acid materials that produce the product allow for different sequences of active substances within each domain at specific times in the washing cycle. The dissolution rate of SDC is influenced by the percentage of slow crystallizing agent (delayed CA%), with high concentrations of SDC (e.g., sample EU) dissolving more slowly than low concentrations of SDC (e.g., sample ER). The absolute dissolution rates at different temperatures are determined by dissolution test methods. The dissolution rate of PEGC is influenced by the molecular weight of PEG, thereby causing sample ER (e.g., PEG10,000) to dissolve more slowly than sample ES (e.g., PEG8,000), and sample ES to dissolve more slowly than sample ET and sample EU (e.g., PEGPEG 6,000). The absolute dissolution rates at different temperatures are determined by dissolution test methods.

[0176] Preparation of the SDC domain Mixing - A 250 ml stainless steel beaker (Thermo Fischer Scientific, Waltham, MA) was placed on a hot plate (VWR, Radnor, PA, 7×7CER Hotplate, catalog number NO97042-690). Water (Milli-Q Academic) and a crystallizer were added to the beaker. A temperature probe was placed in the composition. An overhead mixer (IKA Works Inc, Wilmington, NC, model RW20 DMZ) and a mixing device including a 3-blade impeller design were assembled, and the impeller was placed in the composition. The heater was set to 80°C and the impeller was set to rotate at 250 rpm, and the composition was heated to 80°C until all the crystallizer was solubilized and the composition became clear.

[0177] Formation - The composition was then poured into a Max100 Mid Cup, covered, and allowed to cool to 25°C. A freshness enhancer was added by placing the preparation in a Speedmixer (Flack Tek.Inc, Landrum, SC, model DAC 150.1 FVZ-K) at 3000 rpm for 3 minutes, as specified in the table. In non-limiting examples, the preparation was transferred to a polymer mold patterned with hemispheres of 5 mm in diameter. In another non-limiting example, the preparation was sprayed through an orifice to produce small droplets. The size and shape of the DSC domains were formed to satisfy the final structure of the final low-moisture composition (e.g., Figures 7, 8, 9, and 10). The mold was then placed in a refrigerator (VWR Door Solid Lock F Refrigerator 115V, 76300-508, or equivalent) equilibrated at 4°C for 8 hours to crystallize the crystallizer.

[0178] Drying - The prepared material was placed in a convection oven (Yamato, DKN400, or equivalent) set to 25°C for a further 8 hours, passing a steady flow of air through it to dry the composition. Once completely dry, the prepared material was removed from the mold. The final SDC was confirmed to have a moisture content of less than 10% by a moisture content test method.

[0179] Preparation of PEGC domains Separately, a 250 ml stainless steel beaker (Thermo Fischer Scientific, Waltham, MA) was placed on a hot plate (VWR, Radnor, PA, 7×7 CER Hotplate, catalog number NO97042-690). PEG (materials 8-11) was added to the beaker. An overhead mixer (IKA Works Inc, Wilmington, NC, model RW20 DMZ) and a mixing device including a 3-blade impeller design were assembled, and the impeller was placed in the composition. A temperature probe was also placed in the preparation. The impeller was set to rotate at 250 rpm. The preparation was heated to 100°C until the PEG was completely melted. As specified in the table, a freshness enhancer was added by placing the preparation in a Speedmixer (Flack Tek. Inc, Landrum, SC, model DAC 150.1 FVZ-K) at 3000 rpm for 3 minutes. In non-limiting examples, the preparation was used to produce a low-moisture composition within 5 minutes of reaching the final temperature. In non-limiting examples, the preparation was transferred to a polymer mold patterned with hemispheres of 5 mm in diameter. The size and shape of the DSC domains were formed to satisfy the final structure of the final low-moisture composition (e.g., Figures 7, 8, 9, and 10).

[0180] Preparation of low-moisture compositions Sample ER(5mg)-SDC composition is sprayed as droplets onto a flat sheet, crystallized, and dried. PEGC is sprayed onto a flat sheet and crystallized. Two flat ends are combined to create low-moisture composition particles (e.g., Figure 10). Sample ES(5mg)-SDC composition is sprayed as droplets onto a flat sheet, crystallized, and dried. PEGC is sprayed onto the surface of the SDC composition and crystallized. The low-moisture composition is coated particles (e.g., Figure 8). Sample ET(500mg)-PEGC composition is placed on a flat sheet as a large droplet, crystallized, and dried. SDC is sprayed to generate fine granules, which adhere to the surface of the large droplet. The low-moisture composition is sugar gum droplet-like particles (e.g., Figure 9). Sample EU(500mg)-SDC composition is spray-dried small particles. Small SDC particles are added to the PEGC molten material, and larger droplets are placed on a flat surface to crystallize. The low-moisture composition encapsulates the SDC (e.g., Figure 7).

[0181] In non-limiting cases, the final low-moisture composition for the washing process may contain particles comprising one of the multiple particle combinations described in Sample ER, Sample ES, Sample ET, and Sample EU.
