Abstract

A low moisture content composition includes a solid soluble composition domain having a crystallizing agent and a PEGC domain.

Description

Technical Field

[0001] The low water content composition comprises a solid soluble composition (SDC) domain having a network microstructure formed by a dry sodium fatty acid carboxylate preparation, and a polyethylene glycol domain (PEGC). Background Art

[0002] There are considerable challenges in formulating effective solid soluble compositions. The composition needs to be physically stable, preferably resistant to temperature and moisture, but still be able to perform the desired function by dissolving in solution and leaving little or no material behind. Solid soluble compositions are well known in the art and have been used in several applications such as detergents, oral and body medications, disinfectants, and cleaning compositions.

[0003] Surprisingly, a solid soluble composition (SDC) having a network microstructure formed from dried sodium fatty acid carboxylates can be produced that can contain high levels of actives that are easily solubilized in water and are also both temperature and humidity resistant, allowing for supply chain stability. It was discovered that low water content compositions having both domains of PEGC and SDC offer significant advantages over current solid compositions such as beads, including enhanced solubilization rates, sustainability, moisture control, increased sourcing opportunities, cost reduction, lightweighting for efficient e-commerce shipping, and protection of incompatible chemical ingredients. Summary of the invention

[0004] A low water content composition is provided, comprising: at least one solid soluble composition domain (SDC) having a crystallizing agent; at least one polyethylene glycol domain (PEGC); an active agent; and wherein the crystallizing agent is a sodium salt of a saturated fatty acid having 8 to about 12 carbon atoms; wherein the active agent is present in at least one of the SDC or the PEGC.

[0005] A low moisture content composition is provided which substantially dissolves during normal use and is composed of: a solid soluble composition (SDC) domain made from a crystallizing agent; a polyethylene glycol (PEGC) domain; and water; wherein the crystallizing agent is a sodium fatty acid carboxylate having 8 to about 12 carbon atoms; wherein the amount of water is less than 10% by weight of the final low moisture content composition as determined by the "Moisture Test Method".

[0006] Provided is a method for producing a low water content composition, comprising: mixing - heating a crystallizing agent and an aqueous phase until the crystallizing agent is substantially dissolved, cooling to a temperature before the crystallizing agent significantly crystallizes in the form of a SDCM; forming - forming the SDC into a designed shape and size by cooling the solid soluble composition mixture to below the crystallization temperature and allowing the solid soluble composition mixture to crystallize into an intermediate rheological solid; drying - removing excess water and producing a solid soluble composition (SDC) by removing between about 90% and about 99% of the water (as determined by the "Water Test Method") from the intermediate rheological solid composition to produce a solid soluble composition having an average solubility percentage greater than 5% at 37°C (as determined by the "Dissolution Test Method"); providing polyethylene glycol (PEGC); mixing SDC and PEGC to produce a low water content composition having an SDC domain and a PEGC domain; wherein an active agent is added to at least one of the SDC domain or the PEGC domain.

[0022] The present invention includes low water content compositions that are substantially completely soluble in aqueous environments. The low water content compositions comprise at least one solid soluble composition (SDC) domain having a crystalline network, and at least one polyethylene glycol composition (PEGC) domain. The crystalline network ("network") comprises a relatively rigid three-dimensional interlocking skeletal framework of fibrous crystals formed during processing with a crystallizing agent. The solid soluble compositions of the present invention have a crystallizing agent and a low water content, and are readily soluble in an aqueous environment.

[0023] The present invention may be more readily understood by reference to the following detailed description of exemplary compositions. It should be understood that the scope of the claims is not limited to the specific products, methods, conditions, devices or parameters described herein, and the terminology used herein is not intended to limit the invention protected by the claims.

[0024] As used herein, a "solid soluble composition" (SDC) comprises the crystallizing agent sodium fatty acid carboxylate (which, when properly processed, forms a crystalline network of interconnected fibers that readily dissolves at the target wash temperature), an optional active agent such as a fresh feel benefit agent, and 10% by weight or less of water in the form of solid particles during the initial mixing stage.

[0025] As used herein, a "PEG composition" (PEGC) comprises PEG and optionally a fresh feel benefit agent.

[0026] As used herein, "domain" means a continuous mass comprising substantially the same material. In one embodiment, the domain may include SDC; in another embodiment, the domain may include PEGC.

[0027] As used herein, "low moisture content composition" means a freshness feel composition comprising both domains of SDC and PEGC and a freshness feel benefit agent, and wherein the low moisture content composition has a moisture content of less than about 10% by weight.

[0028] "Consumer products" herein include purchased low-water compositions for at least partially dissolving and releasing one or more active agents. Such products include, but are not limited to: laundry cleaning compositions and detergents, fabric softening compositions, fabric enhancing compositions, fabric refreshing compositions, laundry pre-washes, laundry pre-treaters, laundry additives, spray-on products, dry cleaning agents or compositions, laundry rinse additives, washing additives, post-rinse fabric treatments, ironing aids, unit dose formulations, delayed delivery formulations, detergents contained on or in porous substrates or nonwoven sheets, and other suitable forms that may be apparent to those skilled in the art based on the teachings herein. Such products may be used as pre- and post-treatment agents for washing.

[0029] As used herein, "particles" means discrete masses (or blocks) in a low water content composition, typically with a mass greater than about 5 mg and a size greater than 1 mm. Particles can have different shapes, including but not limited to hemispherical, spherical, plate-like, jelly bear-shaped, and cashew-shaped. Particles can have one or more domains.

[0030] As used herein, a "solid soluble composition mixture" (SDCM) comprises the components of a solid soluble composition before water is removed (e.g., during a mixture stage or a crystallization stage). To produce a solid soluble composition, an intermediate solid soluble composition mixture is first formed that comprises an aqueous phase having an aqueous carrier. The aqueous carrier can be distilled water, deionized water, or tap water. The aqueous carrier can be present in an amount of about 65% to 99.5% by weight, alternatively about 65% to about 90% by weight, alternatively about 70% to about 85% by weight, alternatively about 75% by weight, based on the weight of the SDCM.

[0031] As used herein, "rheological solid composition" (RSC) describes the solid form of the SDCM after crystallization (crystallization stage) and before water is removed to obtain the SDC, wherein the RSC contains more than about 65% by weight water and the solid form results from the "structured" interlocking network (network microstructure) of fibrous crystalline particles from the crystallization agent.

[0032] As used herein, "PEG" includes polyethylene glycol (PEG) having a molecular weight of about 200 Daltons to about 50,000 Daltons, most preferably between about 6,000 Daltons and 10,000 Daltons.

[0033] As used herein and further described below, "freshness benefit agent" includes materials added to the fabric to impart a freshness benefit to the fabric through washing. In an embodiment, the freshness benefit agent can be a pure fragrance; in an embodiment, the freshness benefit agent can be an encapsulated fragrance (fragrance capsule); in an embodiment, the freshness benefit agent can be a mixture of fragrance and / or fragrance capsule.

[0034] As used herein, "crystallization temperature" describes the temperature at which a crystallization agent (or combination of crystallization agents) is completely dissolved in SDCM; alternatively, it describes the temperature at which a crystallization agent (or combination of crystallization agents) exhibits any crystallization in SDCM.

[0035] As used herein, "dissolution temperature" describes the temperature at which a low water content composition completely dissolves in water under normal washing conditions.

[0036] As used herein, "stable temperature" is the temperature at which most (or all) of the SDC domain material and / or the 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 water content composition no longer functions as expected. The stable temperature is the lowest temperature thermal transition determined by the "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 to ensure stability in the supply chain. Those skilled in the art understand how to measure this lowest thermal transition with a differential scanning calorimetry (DSC) instrument.

[0037] As used herein, "humidity stability" is such a relative humidity: at this relative humidity, the low moisture content composition spontaneously absorbs more than 5% by weight of the initial mass of water from the humidity of the surrounding environment at 25°C. Water absorption can occur in the SDC domain and / or the PEGC domain. The absorption of small amounts of water when exposed to a humid environment can achieve a more sustainable packaging. The absorption of large amounts of water risks causing the composition to soften or liquefy, so that it can no longer function as expected. In embodiments of the present invention, the humidity stability may be higher than 70% RH, more preferably higher than 80% RH, more preferably higher than 90% RH, and most preferably higher than 95% RH. Those skilled in the art understand how to measure a 5% weight increase with a DVS (dynamic vapor sorption) instrument, which is further described in the "Humidity Test Method".

[0038] Unless otherwise specified, "cleaning compositions" as used herein include all-purpose or "heavy-duty" detergents in granular or powder form, especially cleaning detergents; all-purpose detergents in liquid, gel or paste form, especially the so-called heavy-duty liquid types; liquid fine fabric detergents; hand dishwashing detergents or light-duty dishwashing detergents, especially those of the high-sudsing type; machine dishwashing detergents, including various pouches, tablets, granules, liquids and rinse-aid types for home and institutional use; liquid cleaning and disinfecting agents, including antibacterial hand wash types, cleaning bars, mouthwashes, denture cleaners, dentifrices, car or carpet washes, bathroom cleaners; hair shampoos and hair rinses; shower gels and bubble baths and metal cleaners; and cleaning aids, such as bleach additives and "stain bars" or pre-treatment products carrying substrates, such as dryer-added papers, dry and moistened wipes and pads, nonwoven substrates and sponges; and sprays and aerosols.

[0039] As used herein, "dissolves during normal use" means that the low water content composition completely dissolves or substantially dissolves during use in an aqueous environment.

[0040] As used herein, the term "bio-based" material refers to a renewable material.

[0041] As used herein, the term "renewable material" refers to a material made from renewable resources. As used herein, the term "renewable resources" refers to a resource produced via a natural process at a rate equivalent to its consumption rate (e.g., within a 100-year period). The resource can be natural or replenished by agricultural technology. Non-limiting examples of renewable resources include plants (e.g., sugar cane, beet, corn, potato, citrus fruit, woody plants, lignocellulose, hemicellulose, fibrous waste), animals, fish, bacteria, fungi and forestry products. These resources can be naturally occurring, hybrids, or genetically engineered organisms. The formation of natural resources such as crude oil, coal, natural gas and peat requires more than 100 years, and they are not considered to be renewable resources. Since at least a portion of the material of the present invention derives from a renewable resource that can isolate carbon dioxide, the use of this material can reduce global warming potential, and reduce fossil fuel consumption.

[0042] As used herein, the term "biobased content" refers to the amount of carbon in a material that is derived from renewable resources as a percentage of the total organic carbon weight (mass) in the material as determined by ASTM D6866-10 Method B.

[0043] The term "solid" refers to the state of a low-water content composition under the conditions of expected storage and use of the composition.

[0044] As used herein, the articles including "a" and "an" when used in a claim should be understood to mean one or more of what is claimed or described.

[0045] As used herein, the terms "including," "comprising," and "containing" are intended to be non-limiting.

[0046] Unless otherwise indicated, all component or composition levels are in terms of the active portion of that component or composition and are exclusive of impurities, for example, residual solvents or by-products, which may be present in commercially available sources of such component or composition.

[0047] Unless otherwise indicated, all percentages and ratios are calculated by weight. Unless otherwise indicated, all percentages and ratios are calculated based on the total composition.

[0048] It should be understood that each maximum numerical limitation given throughout this specification includes each lower numerical limitation, as if such lower numerical limitations were expressly written herein. Each minimum numerical limitation given throughout this specification will include each higher numerical limitation, as if such higher numerical limitations were expressly written herein. Each numerical range given throughout this specification will include each narrower numerical range falling within such wider numerical range, as if such narrower numerical ranges were all expressly written herein.

[0049] Solid soluble composition (SDC) comprises fibrous interlocking crystals ( Figure 1A and Figure 1B ), these interlocking crystals have sufficiently large crystal 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 entrapment and protection of particulate active agents such as freshness benefit agents, such as fragrance capsules ( Figure 2A and Figure 2B ). In an embodiment, the active material is a discrete particle having a diameter of less than 100 μm, preferably less than 50 μm, more preferably less than 25 μm. In addition, the significant voids in the reticular microstructure also allow for the inclusion of liquid active agents such as freshness benefit agents, such as pure fragrances. In an embodiment, up to about 15% by weight of active agent, preferably between 13% and 0.5% by weight of active agent, preferably between 13% and 2% by weight of active agent, most preferably between 10% and 2% by weight of active agent may be added. These voids also provide a path for water to be entrained into the microstructure during washing to accelerate dissolution relative to completely solid compositions.

[0050] Surprisingly, SDC with high dissolution rate, low water content, moisture resistance and thermal stability can be prepared. The sodium salt of long-chain fatty acid (i.e., sodium myristate (NaCl4) to sodium stearate (NaCl8)) can form fibrous crystals. It is generally believed that the crystal growth pattern that leads to fibrous crystal habit reflects the hydrophilic (head group) and hydrophobic (hydrocarbon chain) balance of NaCl4-NaCl8 molecules. As disclosed in the present patent application, although the crystallizer used has the same contribution to hydrophilicity, they have extraordinarily different hydrophobic characteristics due to the shorter hydrocarbon chain of the fatty acid sodium carboxylate adopted. In fact, the carbon chain length is approximately half of the length of the previously disclosed carbon chain (US2021 / 0315783A1). In addition, those skilled in the art recognize that many surfactants (such as alkyl sulfates) are susceptible to significant humidity absorption and significant temperature-induced changes, thereby having the same chain, but having different head groups. The crystallizer group selected in the present invention can achieve all these useful properties.

[0051] Current water-soluble polymers (e.g., separate PEG) are limited to using encapsulated spices as a fragrance enhancer delivery system. Encapsulated spices are delivered in a water-based slurry, and the slurry is limited to containing at most 20% to 30% by weight of encapsulated spices, thereby limiting the total amount of encapsulated spices to about 1.2% by weight. Using an encapsulated fragrance content higher than these contents prevents the water-soluble carrier from solidifying, thereby limiting the delivery of encapsulated spices. As a result, consumers are generally only limited by the limitations of the materials they can add to the washing liquid to make the desired freshness level insufficient. Compared with current water-soluble polymers, the solid soluble composition of the present invention can constitute a component of up to about 18% by weight of the spice capsule, and produces about 15 times of the spice delivery amount. Such a high delivery amount is achieved at least in part by the low water content of the composition of the present invention, and this low water content allows the user to feel a significantly improved freshness ( Figure 3 ).

[0052] The improved performance of the compositions of the present invention compared to existing solid soluble compositions such as freshening laundry beads is believed to be associated with the dissolution rate of the composition matrix. Without being limited by theory, it is believed that if the composition dissolves later in the wash cycle, the encapsulated fragrance is more likely to be deposited on the fabric throughout the wash (TTW) to enhance the freshness performance. The water-soluble polymers currently used in commercially available fabric freshening beads have a limited dissolution rate, where the dissolution rate is set by the limited molecular weight (MW) range of the polyethylene glycol (PEG) used as the dissolution matrix. Therefore, a single PEG bead must work under a certain range of machine and washing conditions, thereby limiting performance. In contrast, by adjusting the ratio of the composition components (e.g., the ratio of sodium laurate (NaL) to sodium caprate (NaD)), the dissolution rate of the composition of the present invention can be adjusted under a certain range of machine and washing conditions ( FIG. 4A to FIG. 4C This allows the opportunity to create a wide range of compositions that can be used in many different wash conditions, where the SDC domains can release the freshness benefit agent at different times in the wash cycle.

[0053] The main commercially available fabric freshness bead preparation process limits the choice of freshness benefit agents; instead, SDC domains can be processed and added to low moisture content compositions. The PEG used to form most current commercial beads must be processed at temperatures above the PEG melting point (between 70°C and 80°C); preparing SDC domains at room temperature allows a wider variety of freshness technologies to be implemented. During implementation, the PEG melting point temperature must be maintained for several hours, and some fragrance raw materials are particularly volatile and therefore flash evaporate during processing. For SDC, the inclusion of fragrance oils is carried out at about 25°C, thereby widening the range of pure fragrance additions. In addition, many fragrance capsule wall constructions will fail at higher processing temperatures, thereby releasing the encapsulated fragrance and making it ineffective in low moisture content compositions. Processing in fragrance capsules at lower temperatures enables a wider range of capsules.

[0054] It is difficult to control water migration in mixed bead compositions (e.g., low and high moisture content beads) using currently used water-soluble polymers because water migrates to the surface of the high moisture content beads. Since the beads are typically packaged in closed packages that minimize moisture transfer into and out of the package, moisture trapped on the surface of the high moisture content beads contacts the surface of the low moisture content beads, causing bead agglomeration and product dispensing problems. In contrast, the structure of solid soluble compositions prevents water migration, thus enabling the use of materials that are sensitive to water absorption (e.g., cationic polymers, bleach).

[0055] As previously discussed, existing bead formulations use PEG (and other structural materials) that are susceptible to degradation when exposed to heat and / or humidity during shipping. To mitigate such degradation, special shipping conditions and / or packaging are often required. The SDC of the present invention has a crystalline structure that is stable over a range of temperature and humidity conditions. The SDC domain preferably exhibits %dm <5% at 70% RH, more preferably %dm <5% at 80% RH, and most preferably %dm <5% at 90% RH ( Figure 5 ), as determined by the Humidity Test Method; and substantially no melting transition at temperatures below 50°C, as determined by the Thermal Stability Test Method ( Figure 6 ). Therefore, no additional resources are required for refrigeration during transportation, nor for plastic packaging to prevent moisture transfer. The inclusion of SDC domains in low water content compositions enables robust protection of freshness benefit agents.

[0056] Finally, without wishing to be limited by theory, it is believed that the high dissolution rate of the solid soluble composition is provided at least in part by the reticular microstructure. This is believed to be important because it is this porous structure that provides the product with a "light feel", as well as the ability to dissolve rapidly relative to compressed tablets, which allows for immediate delivery of the active ingredient during use. It is believed to be important that a single crystallizing agent (or in combination with other crystallizing agents) forms fibers during the preparation of the solid soluble composition. Forming fibers allows the solid soluble composition to retain the active ingredient without the need for compression, which may destroy the microcapsules.

[0057] In an embodiment, the fibrous crystals may have a minimum length of 10 μm and a thickness of 2 μm as determined by the Fiber Test Method.

[0058] In embodiments, the active ingredient may be in the form of particles that may be: a) uniformly dispersed within the mesh microstructure; b) applied to the surface of the mesh microstructure; or c) partially dispersed within the mesh microstructure and partially applied to the surface of the mesh microstructure. In embodiments, the active ingredient may be: a) in the form of a soluble film on the top surface of the mesh microstructure; b) in the form of a soluble film on the bottom surface of the mesh microstructure; or c) in the form of a soluble film on both the bottom and top surfaces of the mesh microstructure. The active ingredient may be present as a combination of a soluble film and particles. Non-limiting examples of particles are presented in Figure 7 , Figure 8 , Fig. 9 and Fig.10 middle.

[0059] Crystallization agent

[0060] The crystallization agent is selected according to its ability to impart different properties to the SDC domain. The crystallization agent is selected from sodium carboxylates of small-group fatty acids with saturated chains and chain lengths ranging from C8 to C12. Within this composition range, using the preparation method described, such sodium carboxylates of fatty acids provide a fibrous network microstructure, an ideal solubilization temperature for dissolution in preparation and use, and through appropriate blending, the resulting solid soluble composition has adjustability in these properties for various uses and conditions.

[0061] Crystallization agent can be present in the solid soluble composition mixture for producing SDC domains in an amount of about 5 wt % to about 35 wt %, about 10 wt % to about 35 wt %, or about 15 wt % to about 35 wt %. Crystallization agent can be present in the SDC domain in an amount of about 50 wt % to about 99 wt %, about 60 wt % to about 95 wt %, about 70 wt % to about 90 wt %. Crystallization agent can be present in the low water content composition in an amount of about 5 wt % to about 60 wt %, about 10 wt % to about 50 wt %, about 15 wt % to about 40 wt %.

[0062] Suitable crystallizing agents include sodium caprylate (NaC8), sodium caprate (NaC10), sodium dodecanoate or sodium laurate (NaC12), and combinations thereof.

[0064] The capsule may include a wall material (active agent delivery capsule or simply "capsule") that encapsulates an active agent (described below) such as a freshness benefit agent.

[0146] It will be appreciated that combinations of the quaternary ammonium compounds disclosed above are suitable for use in the present invention.

[0147] In the cationic nitrogenous salts herein, the anion A- is any anion compatible with the softener that provides electrical neutrality. Most commonly, the anions used to provide electrical neutrality in these salts come from strong acids, especially halides, such as chloride, bromide, or iodide. However, other anions, such as methyl sulfate, ethyl sulfate, acetate, formate, sulfate, carbonate, etc., may be used. Chloride and methyl sulfate may be anions A. Anions may also be doubly charged, in which case A- represents half a group.

[0148] The low moisture content composition may comprise from about 10% to about 40% by weight of the quaternary compound.

[0149] The iodine value of a quaternary ammonium compound is that of the parent fatty acid from which the compound is formed and is defined as the number of grams of iodine which react with 100 grams of the parent fatty acid from which the compound is formed.

[0150] First, the quaternary ammonium compound is hydrolyzed according to the following protocol: 25 g of the quaternary ammonium compound is mixed with 50 mL of water and 0.3 mL of sodium hydroxide (50% active). The mixture is boiled on a hot plate for at least one hour while avoiding the mixture from drying out completely. After one hour, the mixture is cooled and the pH is adjusted to neutral (pH between 6 and 8) with 25% sulfuric acid using pH test strips or a calibrated pH electrode.

[0151] Next, extract fatty acids from the mixture via liquid-liquid extraction acidified with hexane or petroleum ether: dilute the sample mixture to 160mL with water / ethanol (1:1) in an extraction cylinder, add 5 grams of sodium chloride, 0.3mL sulfuric acid (25% activity) and 50mL hexane. Stopper the cylinder and shake for at least 1 minute. Then, allow the cylinder to stand until 2 layers are formed. The top layer containing the fatty acid hexane solution is transferred to another container. Then use a hot plate to evaporate the hexane, leaving the extracted fatty acids.

[0152] Next, the iodine value of the parent fatty acid forming the fabric softening active substance is determined according to ISO3961:2013. The method for calculating the iodine value of the parent fatty acid includes dissolving a predetermined amount (0.1-3g) in 15mL chloroform. Then the dissolved parent fatty acid is reacted with 25mL acetic acid solution (0.1M) of iodine monochloride. 20mL 10% potassium iodide solution and 150mL deionized water are added thereto. After the halogen has been added, the excess iodine monochloride is determined by titrating with sodium thiosulfate solution (0.1M) in the presence of blue starch indicator powder. At the same time, the blank is determined under the same conditions with the same amount of reagent. The difference between the volume of sodium thiosulfate used in the blank and the volume of sodium thiosulfate used in the reaction with the parent fatty acid can calculate the iodine value.

Without being bound by theory, it is believed that the cleaning performance of the laundry detergent in the wash decreases as the cationic polymer content in the low water content composition increases, and the acceptable cleaning performance of the detergent can be maintained within the above range.

[0159] The cationic polymer may have a cationic charge density of more than about 0.05 meq / g (meq means milliequivalent) to 23 meq / g, preferably from about 0.1 meq / g to about 4 meq / g, even more preferably from about 0.1 meq / g to about 2 meq / g, and most preferably from 0.1 meq / g to about 1 meq / g.

The cationic charge density of a polymer refers to the ratio of the number of positive charges on the polymer to the molecular weight of the polymer. The charge density is calculated by dividing the net number of charges per repeating unit by the molecular weight of the repeating unit. The positive charge can be located on the polymer backbone and / or on the polymer side chains. The average molecular weight of such a suitable cationic polymer can generally be between about 10,000 and about 10 million, or even between about 50,000 and about 5 million, or even between about 100,000 and about 3 million.

[0244] Vitamins

[0245] As used herein, "xanthine compound" means one or more xanthines, their derivatives, and mixtures thereof. Xanthine compounds useful herein include, but are not limited to, caffeine, xanthine, 1-methylxanthine, theophylline, theobromine, their derivatives, and mixtures thereof. Among these compounds, caffeine is preferred in view of its solubility in the composition. The composition may contain by weight from about 0.05%, preferably from about 2.0%, more preferably from about 0.1%, still more preferably from about 1.0%, and to about 0.2%, preferably to about 1.0%, more preferably to about 0.3% of xanthine compounds.

[0246] As used herein, "vitamin B3 compound" refers to one or more compounds having the formula:

[0247]

[0248] Wherein R is -CONH2 (ie nicotinamide), -COOH (ie nicotinic acid) or -CH2OH (ie nicotinic alcohol); their derivatives; their mixtures; and salts of any of the foregoing substances.

[0249] Exemplary derivatives of the foregoing vitamin B3 compounds include nicotinic acid esters, including non-vasodilating nicotinic acid esters (e.g., tocopheryl nicotinate and myristyl nicotinate), nicotinyl amino acids, nicotinyl alcohol esters of carboxylic acids, nicotinic acid N-oxide, and nicotinamide N-oxide. The composition may contain from about 0.05%, preferably from about 2.0%, more preferably from about 0.1%, still more preferably from about 1.0%, and to about 0.1%, preferably to about 0.5%, more preferably to about 0.3% by weight of the vitamin B3 compound.

[0250] As used herein, the term "panthenol compound" is broad enough to include panthenol, one or more pantothenic acid derivatives, and mixtures thereof. Panthenol and its derivatives may include D-panthenol ([R]-2,4-dihydroxy-N-[3-hydroxypropyl]-3,3-dimethylbutyramide), DL-panthenol, pantothenic acid and its salts (preferably calcium salts), panthenol triacetate, royal jelly, pantethine, panthenylthioethylamine, panthenyl ethyl ether, pancreatic acid, pantothenic acid lactose, vitamin B complexes, or mixtures thereof.

[0251] Sodium chloride (and other sodium salts) are particularly useful additives to the aqueous phase to adjust the thermal stability of the composition, but must be added to the composition with particular care (Example 3). Without wishing to be bound by theory, sodium chloride is thought to "salt out" the crystallizer of the present invention, thereby reducing its solubility. This has the effect of increasing the thermal stability temperature of the rheological solid composition, as measured by the thermal stability test method. For example, the crystallizer of the optimal chain length can have a thermal stability temperature increased by up to 15°C after the addition of sodium chloride. This is particularly valuable because the addition of other ingredients to the aqueous phase in the absence of sodium chloride typically reduces the thermal stability temperature. Surprisingly, the addition of sodium chloride can cause adverse effects in the preparation of rheological solid compositions. In most preparation methods, sodium chloride is preferably added to the hot crystallizer aqueous phase before cooling to form a network. However, too much addition may result in "coagulation" of the crystallizer and an absolutely unpleasant composition. Sodium chloride can also be added after the network is formed to provide the beneficial effect of increasing the thermal stability temperature at a higher level without coagulation. Finally, while the thermal stability temperature increases with the addition of sodium chloride, the addition of other non-sodium salts can also change the fibrous nature of the crystals formed by the crystallizing agent to form flake or plate-like crystals that are not rheologically solid.

[0271] Dissolution Test Method

[0272] All samples and procedures were kept at room temperature (25 ± 3°C) prior to testing and then placed in a desiccant chamber (0% RH) for 24 hours or until they reached constant weight.

[0273] All dissolution measurements were carried out at controlled temperature and constant stirring rate. Attached 600mL jacketed beaker (Cole-Palmer, product number UX-03773-30, or equivalent), water was circulated through the jacketed beaker using a water circulator (Fisherbrand Isotemp 4100, or equivalent) set to the desired temperature to cool to a certain temperature. The jacketed beaker was centered on the stirring element of a VWR multi-position stirrer (VWR North American, West Chester, Pa., USA catalog number 12621-046). 100mL deionized water (model 18MΩ, or equivalent) and a stirring bar (VWR, Spinbar, catalog number 58947-106, or equivalent) were added to a second 150mL beaker (VWR North American, West Chester, Pa., USA catalog number 58948-138, or equivalent). Place the second beaker into the jacketed beaker. Add enough Millipore water to the jacketed beaker to bring it above the water level in the second beaker, being very careful so that the water in the jacketed beaker does not mix with the water in the second beaker. The speed of the stir bar is set to 200 RPM, enough to create a gentle vortex. The temperature in the second beaker is set to reach 25°C or 37°C using water flow from a water circulator, the relevant temperatures are reported in the examples. Before performing the dissolution experiment, measure the temperature in the second beaker with a thermometer.

[0274] All samples were sealed in a desiccator prepared with fresh desiccant (VWR, Indicating Anhydrous Drierite, Stock No. 23001, or equivalent) until constant weight was reached. The mass of all tested samples was less than 15 mg.

[0275] Take out a single sample from the desiccator for a single dissolution test. After taking the sample out of the desiccator, weigh it within 1 minute and measure the initial mass (M I ). The sample is dripped into the second beaker under stirring. The sample is allowed to dissolve for 1 minute. At the end of this minute, the sample is carefully removed from the deionized water. The sample is placed in the desiccator again until a constant final mass is reached. The percentage mass loss of the sample in a single experiment is calculated as M L =100*(M I -M F ) / M I calculate.

[0276] Nine additional dissolution experiments were performed: first replacing 100 ml of water with fresh deionized water, adding new sample to the desiccator for each experiment, and then repeating the dissolution experiment described in the previous paragraph.

[0277] The average mass loss percentage of the test (M A ) was calculated based on the average mass loss percentage of these ten experiments, and the standard deviation of the average mass loss (SD A ) is the standard deviation of the average mass loss percentage of these ten experiments.

[0278] This method returns three values: 1) the average mass of the sample (M S ), 2) the temperature at which the sample dissolved (T), and 3) the average percent mass loss (M A If the method is not performed on a sample, the method returns "NM" for all values. Average mass loss percentage (M A ) and the average standard deviation (SD A ) is used to draw Figure 4A , Figure 4B and Figure 4C Dissolution curves used in this study.

[0279] Humidity test method

[0280] The humidity test method is used to determine the amount of water vapor adsorption that occurs when a composition is dried at 0% RH and various RH at 25°C. In this method, 10 mg to 60 mg of sample are weighed and the mass changes associated with conditioning with different environmental states are captured in a dynamic vapor sorption instrument. The resulting mass increase is expressed as a mass change per % of the mass of the dried sample recorded at 0% RH.

[0281] The method uses an SPSx vapor sorption analyzer with 1 μg resolution (ProUmid GmbH & Co. KG, Ulm, Germany), or an equivalent dynamic vapor sorption (DVS) instrument capable of controlling the relative humidity percentage (%RH) within ±3%, the temperature within ±2°C, and the mass measurement accuracy within ±0.001 mg.

[0282] 10 mg to 60 mg of the raw material or composition sample is evenly dispersed into a tared 1" diameter aluminum pan. The aluminum pan with the raw material or composition sample dispersed thereon is placed in a DVS instrument set to 25°C and 0% RH. At this set point, the mass is recorded approximately every 15 minutes to an accuracy of 0.001 mg or better. After the sample has been in the DVS at this environmental setting for at least 12 hours and a constant weight has been reached, the mass of the sample, md, is recorded to an accuracy of 0.01 mg or better. After this step is completed, the instrument is advanced in 10% RH increments until 90% RH. The sample is maintained in the DVS for at least 12 hours at each step until a constant weight has been reached. The mass of the sample, md, is recorded at each step. n , to an accuracy of 0.001mg or better.

[0283] For a particular sample, constant weight can be defined as the mass variation of successive weighings not exceeding 0.004%. For a particular sample, the mass variation per dry sample mass (% dm) is defined as

[0284]

[0285] % Mass change is reported in % per dried sample mass to the nearest 0.01%.

[0286] Humidity stability at 80% RH means a change at 80% RH of less than or equal to 5%; no humidity stability at 80% RH means a change at 80% RH of greater than 5%.

[0287] Thermal stability test method

[0288] All samples and procedures were maintained at room temperature (25 ± 3°C) prior to testing and at a relative humidity of 40% ± 10% for 24 hours prior to testing.

[0289] In the thermal stability test method, a 20 mg ± 10 mg sample of the sample composition is subjected to differential scanning calorimetry (DSC). A simple scan is performed between 25°C and 90°C, and the temperature at which the maximum peak is observed is reported as the stable temperature, accurate to the nearest °C.

[0290] The sample was loaded into the DSC pan. All measurements were performed in a high capacity stainless steel pan set (TA part number 900825.902). The pan, lid, and liner were weighed and tared on a Mettler Toledo MT5 analytical microbalance (or equivalent; Mettler Toledo, LLC., Columbus, OH). The sample was loaded into the pan according to the manufacturer's instructions with a target weight of 20 mg (+ / - 10 mg), taking care to ensure that the sample was in contact with the bottom of the pan. The pan was then sealed with a TA high capacity die set (TA part number 901608.905). The final assembly was measured to obtain the sample weight. The sample was loaded into a TA Q Series DSC (A Instruments, New Castle, DE) according to the manufacturing instructions. The DSC program used the following settings: 1) equilibrate at 25°C; 2) mark the end point of cycle 1; 3) heat up to 90.00°C at 1.00°C / min; 4) mark the end point of cycle 3; then 5) end the method; click Run.

[0291] Moisture Testing Methods

[0292] All samples and procedures were maintained at room temperature (25 ± 3°C) prior to testing and at a relative humidity of 40% ± 10% for 24 hours prior to testing.

[0293] The moisture test method is used to quantify the weight percentage of water in a composition. In this method, a Karl Fischer (KF) titration is performed on each of three similar samples of the sample composition. A volumetric KF titration apparatus is used and the titration is performed using a single component solvent system. The sample mass is 0.3 g ± 0.05 g and is allowed to dissolve in the titration vessel for 2.5 minutes prior to titration. The average (arithmetic mean) water content of the three replicates is recorded to the nearest 0.1 weight % of the sample composition.

[0294] In order to measure the water content of the sample, a Mettler Toledo V30S volumetric KF titrator was used for measurement. The instrument used Honeywell Fluka Hydraanal solvent (catalog number 34800-1L-US) to dissolve the sample, used Honeywell Fluka Hydranal titrant-5 (catalog number 34801-1L-US) to titrate the sample, and was equipped with three drying tubes filled with Honeywell Fluka Hydranal 3nm molecular sieves (catalog number 34241-250g) to maintain the efficacy of anhydrous materials.

[0310] Fiber Test Methods

[0311] The Fiber Test Method is used to determine whether a solid soluble composition crystallizes under process conditions and contains fibrous crystals. A fiber is simply defined as a "filament, or a filament-like structure or object." A fiber has a long length in only one direction ( Figure 1A and Figure 1B This is different from other crystal forms, such as plates or flakes, which have long lengths in two or more directions ( Fig.11A and Fig. 11B Only solid soluble compositions in which the DCS is a fiber fall within the scope of the present invention. One skilled in the art will recognize the SDC domain from the PEGC domain in a solid soluble composition provided that the two domains are present in the same particle.

[0312] The sample measuring about 4 mm in diameter was mounted on a SEM sample shuttle and sample holder (Quorum Technologies, AL200077B and E7406) slit-precoated with a 1:1 mixture of Scigen Tissue Plus optimal cutting temperature (OCT) compound (Scigen 4586) and colloidal graphite (Agar Scientific G303E). The mounted sample was placed in a liquid nitrogen-slush bath and plunge-frozen. Next, the frozen sample was inserted into a Quorum PP3010T cryopreparation chamber (Quorum Technologies PP3010T) or equivalent and equilibrated to -120°C before freeze-fracture. Frozen fracture was performed by splitting the top of the glassy sample using an ice-cold built-in knife in the cryopreparation chamber. Additional sublimation was performed at -90°C for 5 minutes to remove residual ice on the sample surface. The sample was further cooled to -150 °C and sputter-coated with a layer of Pt, which was kept in a cryo-preparation chamber for 60 s to mitigate charging.

[0313] High-resolution imaging was performed in a Hitachi Ethos NX5000 FIB-SEM (Hitachi NX5000) or equivalent.

[0314] To determine the fiber morphology of the sample, imaging was performed at 20,000× magnification. At this magnification, single crystals of the crystallization agent can be observed. The magnification can be slightly adjusted to lower or higher values ​​until single crystals are observed. One skilled in the art can assess the longest dimension of a representative crystal in the image. If the longest dimension is about 10 times or more of the other orthogonal dimensions of the crystal, the crystals are considered fibers and are within the scope of the present invention.

[0315] Example

[0316] These examples provide non-limiting examples of low moisture content compositions comprising solid soluble composition (SDC) domains having a network microstructure formed from a dry sodium fatty acid carboxylate formulation, polyethylene glycol (PEGC) domains, and active agents such as freshness benefit agents dispersed into these domains that deliver exceptional freshness to fabrics.

[0317] The present compositions exhibit particles comprising SDC domains with a crystallizing agent which, when properly processed, forms a fibrous web that completely dissolves within a wash cycle. The present compositions also exhibit PEGC domains which, when used in combination with SDC domains, produce a unique low water content composition that is easy to process, provides unique aesthetic properties and enhanced freshness performance.

[0318] The freshness benefit agent takes the form of perfume capsules and / or pure perfume distributed in different domains. Example 1 shows a particle composed of two or more domains, where the SDC domain is smaller and completely enclosed in a single PEGC domain ( Figure 7 Example 2 demonstrates particles composed of two or more domains, wherein a single SDC domain is coated with a PEGC domain coating and is completely enclosed in the PEGC domain coating ( Figure 8 Example 3 shows particles composed of two or more domains, wherein the core of these particles is a PEGC domain and is interspersed with SDC domains ( Fig. 9 Example 4 shows particles composed of two or more domains, wherein one side of the particles contains a PEGC domain and the other side contains a SDC domain ( Fig.10). Example 5 presents a low moisture composition consisting of a physical mixture of two or more different types of particles and a novelty benefit agent, some of which are constructed as described in Examples 1 to 4. Example 6 presents a composition made from a specific blend of fatty acid materials that are neutralized with and blended with PEGC to produce a solid soluble composition and blended with fragrance capsules having different wall configurations.

[0319] The data in Tables 1 to 8 provide parameters about the particles in the following manner:

[0320] preparation SDC Domain - All weights listed in this section of the table correspond to the amount added to produce the solid soluble composition mixture (SDCM). "% Freshener (Dry)" is the weight percent of freshener remaining in the SDC after drying, assuming no remaining water, as determined by the "Moisture Test Method". "% Slow CA" is the weight percent of NaCl2 (slowly dissolving) in a mixture of NaCl2 with NaClO and NaC8 (fast dissolving).

[0321] All SDC domains were prepared in three fabrication steps to ensure the formation of a fiber mesh in the domains:

[0322] 1. mix - wherein the crystallization agent is completely dissolved in water to form the SDCM, optionally with the addition of an active agent;

[0323] 2. Forming - wherein the composition resulting from the mixing step is shaped according to the size and dimensions of the desired SDC by techniques including crystallization;

[0324] 3. dry - wherein the amount of water is reduced to ensure the desired properties, including dissolution, hydration and thermal stability, optionally with the addition of active agents.

[0325] Preparation of PEGC domain , all weights listed in this section of the table correspond to the amounts of PEG and freshener added to produce the PEGC. Any water added to this domain by including a fragrance capsule slurry is used when combining to form a low moisture composition. No Removed and stay to become part of the domain.

[0326] Low water content composition, all weights listed in this section of the table correspond to the amounts of SDC and PEGC combined to produce the low water content composition particles. For clarity, the percentages of the components in the low water content composition are provided as follows: "% CA", which is equal to the crystallization agent from SDC in the final low water content composition; "% flavor capsules", which is equal to the flavor capsules in the final low water content composition; "% flavor", which is equal to the pure flavor in the low water content composition; "% PEG", which is equal to the PEG in the low water content composition; "% water", which is equal to the water in the low water content composition, including the water not removed from the PEGC. Finally, "Average Mass" = the average mass of the particles produced from the low water content composition as described in each example.

[0327] The data in Tables 9-10 provide contemplated particles consisting solely of SDC domains with varying blends of crystalline agents and freshness benefit agents and PEGC domains with varying molecular weights of PEG and freshness benefit agents.

[0328] The data in Tables 11 to 12 provide a contemplated low-water composition comprising a physical mixture of particles having an SDC domain, a PEGC domain, and a freshness benefit agent. The amount of "perfume capsules in the wash liquor" is the dose of perfume capsules in the wash liquor that delivers the desired dry fabric feel benefit to the consumer. The amount of "pure perfume in the wash liquor" is the amount of pure perfume in the wash liquor that delivers the desired wet fabric feel benefit to the consumer. The @ symbol shown with the particles represents the mass of the particles in the low-water composition. The "composition dose" is the sum of all particles in the low-water composition and the amount added by the consumer to the wash liquor.

[0329] The data in Table 13 provide contemplated low moisture compositions comprising SDC domains prepared from a mixture of C8, C10, and C12 chain length fatty acids that are neutralized to produce SDC domains that are then combined with PEGC domains and with flavor capsules having different wall configurations.

[0348] Example 1

[0349] Example 1 demonstrates particles composed of two or more domains, wherein an SDC domain is completely enclosed within a single PEGC domain ( Figure 7 ).

[0350] This embodiment demonstrates the existence of compositions that can use different domains in a single particle to adjust the amount and distribution of different freshness benefit agents. In this non-limiting embodiment, the SDC domain is dispersed in the continuous domain of PEGC. This provides several advantages. First, the SDC domain provides an opportunity to increase the amount of flavor capsules in the particle (e.g., about 18% by weight) relative to a single PEGC domain (e.g., about 1.2% by weight). Second, these particles maintain a "smooth" appearance due to PEGC to enhance the aesthetics of the particles. Third, such compositions provide advantages for manufacturing, wherein the flow properties of the "molten" composition are similar to the flow properties of the full PEG composition, thereby providing the potential for preparing these composite compositions on existing commercial equipment. Samples AA to AI are non-limiting examples of the composition and weight ratio of different domains that may be present in the resulting particles, which can be used as low water content compositions.

[0351] preparation SDC Domain

[0352] Mixing - Place a 250 ml stainless steel beaker (Thermo Fischer Scientific, Waltham, MA.) on a hot plate (VWR, Radnor, PA, 7×7 CER hot plate, catalog number NO97042-690). Add water (Milli-Q Academic) and crystallization agent to the beaker. Place a temperature probe in the composition. Assemble a mixing apparatus including an overhead mixer (IKA Works Inc, Wilmington, NC, model RW20 DMZ) and a three-blade impeller design and place the impeller in the preparation. Set the heater to 80° C., set the impeller to rotate at 250 rpm, and then heat the composition to 80° C., or until all the crystallization agent is dissolved and the composition is clear. The preparation is then poured into a Max 100 Mid cup (Speed ​​Mixer), covered, and allowed to cool to 25° C. The preparation was spun in a Speedmixer (Flack Tek. Inc, Landrum, SC, Model DAC 150.1FVZ-K) at 3000 rpm for 3 minutes to add the fresh feel benefit agents as indicated in the table.

[0353] Forming - The preparation was poured onto aluminum foil to a uniform thickness of about 1 mm. The preparation was then placed in a refrigerator (VWR Door Solid Lock F refrigerator, 115V, 76300-508, or equivalent) equilibrated to 4°C for 8 hours to allow the crystallization agent to crystallize.

[0354] Drying - Place the preparation in a convection oven (Yamato, DKN400 or equivalent) set at 25°C for an additional 8 hours with a steady stream of air to dry the composition. Confirm that the final SDC has less than 10% moisture by the "Moisture Test Method". The domains are in the shape of the molds, or the flat plate is broken into coarse pieces of approximately 1 mm x 1 mm in size.

[0355] preparation PEGC domain

[0356] Separately, a 250 ml stainless steel beaker (Thermo Fischer Scientific, Waltham, MA.) was placed on a hot plate (VWR, Radnor, PA, 7×7 CER hot plate, catalog number NO97042-690). PEG (materials 8-11) was added to the beaker. A mixing apparatus including an overhead mixer (IKA Works Inc, Wilmington, NC, model RW20 DMZ) and a three-blade impeller design was assembled and the impeller was placed in the preparation. 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. The preparation was placed in a Speedmixer high-speed mixer (Flack Tek. Inc, Landrum, SC, model DAC 150.1FVZ-K) and rotated at a rate of 3000 rpm for 3 minutes to add a fresh feeling benefit agent as indicated in the table. This preparation is used to prepare low water content compositions within 5 minutes of reaching the final temperature.

[0357] Preparation of low water content compositions

[0358] The 60 ml Speed ​​Mixer cup and lid were weighed. The lid was removed and the SDC domains were added to the cup. The cup was resealed with the lid and reweighed, and the mass of the SDC domains in the preparation was the weight difference.

[0359] Weigh a second 60 ml Speed ​​Mixer cup and lid. Remove lid and add freshness benefit agent to cup. Reseal cup with lid and re-weigh, where the mass of freshness benefit agent in preparation is the weight difference. Remove lid from cup again.

[0360] Within 30 seconds, PEGC was added to the cup, the lid was replaced, and the entire preparation was reweighed, where the mass of PEGC in the preparation was the weight difference. The cup was placed in a Speedmixer, started, and the preparation was mixed at 3,000 RPM for 1 minute. After mixing, within 30 seconds (and before crystallization), the preparation was transferred to a polymer mold patterned with 5 mm diameter hemispheres. The preparation was allowed to cool at 25°C for at least 30 minutes. The structure of the particles in the low water content composition is shown in Figure 7 Shown in.

[0388] Example 2

[0389] Example 2 demonstrates particles composed of two or more domains, wherein a single SDC domain is coated with a PEGC domain coating and is completely enclosed in the PEGC domain coating ( Figure 8 ).

[0390] This embodiment shows a composition in which particles having an SDC domain core and a PEGC coating are included. In this non-limiting embodiment, a single SDC domain is enclosed in a continuous PEGC domain. This has several advantages. These particles provide an opportunity to increase the amount of fragrance capsules in the SDC domain (e.g., up to about 18% by weight) relative to the amount of fragrance capsules in the SDC domain (e.g., only up to about 1.3% by weight). These particles are increased to about 10 times in terms of the capacity of the freshness benefit agent. The density of the SDC domain is also reduced by about 50% to 70%, making the particles (and the resulting low-water content composition) more suitable for different commercial approaches (such as e-commerce approaches), the carrier required for unit freshness is less and more sustainable, and it is more sustainable to replace petroleum-based PEG with natural crystallizers. In addition, the use of a PEGC coating allows the particles to maintain the "smooth" or shiny appearance of the PEGC domain, which is valued by many consumers. Samples BA to BI are non-limiting examples of the composition and weight ratio of different domains that may be present in the resulting particles.

[0391] Preparation of SDC domain

[0392] Mixing - Place a 250 ml stainless steel beaker (Thermo Fischer Scientific, Waltham, MA.) on a hot plate (VWR, Radnor, PA, 7×7 CER hot plate, catalog number NO97042-690). Add water (Milli-Q Academic) and crystallization agent to the beaker. Place a temperature probe in the composition. Assemble a mixing apparatus including an overhead mixer (IKA Works Inc, Wilmington, NC, model RW20 DMZ) and a three-blade impeller design and place the impeller in the preparation. Set the heater to 80° C., set the impeller to rotate at 250 rpm, and then heat the composition to 80° C., or until all the crystallization agent is dissolved and the composition is clear. The preparation is then poured into a Max 100 Mid cup (Speed ​​Mixer), covered, and allowed to cool to 25° C. The preparation was spun in a Speedmixer (Flack Tek. Inc, Landrum, SC, Model DAC 150.1FVZ-K) at 3000 rpm for 3 minutes to add the fresh feel benefit agents as indicated in the table.

[0393] Forming - The preparation was transferred to a polymer mold patterned with a 5 mm diameter hemisphere. The preparation was then placed in a refrigerator equilibrated to 4°C (VWR Door Solid Lock F refrigerator, 115V, 76300-508, or equivalent) for 8 hours to allow the crystallization agent to crystallize.

[0394] Drying - Place the preparation in a convection oven (Yamato, DKN400 or equivalent) set at 25°C for an additional 8 hours with a steady stream of air to dry the composition. Confirm that the moisture of the final SDC is less than 10% by the "Moisture Test Method".

[0395] Preparation of PEGC domain

[0396] Separately, a 250 ml stainless steel beaker (Thermo Fischer Scientific, Waltham, MA.) was placed on a hot plate (VWR, Radnor, PA, 7×7 CER hot plate, catalog number NO97042-690). PEG (materials 8-11) was added to the beaker. A mixing apparatus including an overhead mixer (IKA Works Inc, Wilmington, NC, model RW20 DMZ) and a three-blade impeller design was assembled and the impeller was placed in the preparation. 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. The preparation was placed in a Speedmixer high-speed mixer (Flack Tek. Inc, Landrum, SC, model DAC 150.1FVZ-K) and rotated at a rate of 3000 rpm for 3 minutes to add a fresh feeling benefit agent as indicated in the table. This preparation is used to prepare low water content compositions within 5 minutes of reaching the final temperature.

[0397] Preparation of low water content compositions

[0398] Measure the weight of the weighing boat. Place the SDC in the weighing boat, wherein the weight of the SDC is determined by the difference in mass. Immerse the SDC in the PEGC melt. Wipe off excess PEGC from the surface of the SDC. Place the preparation in a weighing boat. Allow the preparation to cool at 25°C for at least 30 minutes. Measure the weight of the weighing boat, wherein the weight of the fragrance is determined by the difference in weight. A diagram of the structure of the particles in the low water content composition is shown in Figure 8 Shown in.

[0425] Example 3

[0426] Example 3 demonstrates particles composed of two or more domains, wherein the core of these particles is a PEGC domain interspersed with SDC domains ( Fig. 9 ).

[0427] Such particles provide the opportunity that each domain has dissolution characteristics independently for particles with a large number of PEGC domains and SDC domains, for example. In non-limiting samples CA and CB, the flavor capsules are placed in the SDC domains and released into the washing cycle at a rate consistent with the composition of the crystallization agent blend, and the pure flavors are placed in the PEGC domains and released into the washing cycle at a rate consistent with the molecular weight of PEG. Compared with the particles described in, for example, Example 1, the solubility percentage determined by the "dissolution test method" is now independent of different domains. In addition, this form is aesthetically advantageous for consumers because the attached domains send signals that prompt different functions in the particles. In addition, this form is easy to prepare commercially-for example, warm PEGC domains are passed through "sporadic" SDC domain particles, which can adhere to the domain surface.

[0428] Preparation of SDC domain

[0429] Mixing - Place a 250 ml stainless steel beaker (Thermo Fischer Scientific, Waltham, MA.) on a hot plate (VWR, Radnor, PA, 7×7 CER hot plate, catalog number NO97042-690). Add water (Milli-Q Academic) and crystallization agent to the beaker. Place a temperature probe in the composition. Assemble a mixing apparatus including an overhead mixer (IKA Works Inc, Wilmington, NC, model RW20 DMZ) and a three-blade impeller design and place the impeller in the preparation. Set the heater to 80° C., set the impeller to rotate at 250 rpm, and then heat the composition to 80° C., or until all the crystallization agent is dissolved and the composition is clear. The preparation is then poured into a Max 100 Mid cup (Speed ​​Mixer), covered, and allowed to cool to 25° C. The preparation was spun in a Speedmixer (Flack Tek. Inc, Landrum, SC, Model DAC 150.1FVZ-K) at 3000 rpm for 3 minutes to add the fresh feel benefit agents as indicated in the table.

[0430] Forming - The preparation was poured onto aluminum foil to a uniform thickness of about 1 mm. The preparation was then placed in a refrigerator (VWR Door Solid Lock F refrigerator, 115V, 76300-508, or equivalent) equilibrated to 4°C for 8 hours to allow the crystallization agent to crystallize.

[0431] Drying - Place the preparation in a convection oven (Yamato, DKN400 or equivalent) set at 25°C for an additional 8 hours with a steady stream of air to dry the composition. Confirm that the final SDC has less than 10% moisture by the "Moisture Test Method". Break the plaque into coarse pieces of approximately 1 mm x 1 mm in size.

[0432] Preparation of PEGC domain

[0433] Separately, a 250 ml stainless steel beaker (Thermo Fischer Scientific, Waltham, MA.) was placed on a hot plate (VWR, Radnor, PA, 7×7 CER hot plate, catalog number NO97042-690). PEG (materials 8-11) was added to the beaker. A mixing apparatus including an overhead mixer (IKA Works Inc, Wilmington, NC, model RW20 DMZ) and a three-blade impeller design was assembled and the impeller was placed in the preparation. 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. The preparation was placed in a Speedmixer high-speed mixer (Flack Tek. Inc, Landrum, SC, model DAC 150.1FVZ-K) and rotated at a rate of 3000 rpm for 3 minutes to add a fresh feeling benefit agent as indicated in the table. This preparation is used to prepare low water content compositions within 5 minutes of reaching the final temperature.

[0434] Preparation of low water content compositions

[0435] A small amount of PEGC was placed in a weighing boat and weighed. Before significant crystallization (within 30 seconds), a small amount of SDC was lightly sprinkled on the PEGC. Small-sized SDC domains adhered to the surface of the PEGC domains as crystalline material. The preparation was allowed to cool at 25°C for at least 30 minutes. The resulting particles were removed from the mold and reweighed to determine the relevant amount of SDC. The structure of the particles in this low water content composition is shown in Fig. 9 Shown in.

[0444] Example 4

[0445] Example 4 demonstrates particles composed of two or more domains, wherein the particles contain a PEGC domain on one side and an SDC domain on the other side ( Fig.10 ).

[0446] Such particles also provide, for example, particles with a large number of PEGC domains and SDC domains, with the opportunity for each domain to have independent dissolution characteristics. In the non-limiting examples of samples DA and DB, the flavor capsules are placed in the SDC domains and released into the wash cycle at a rate consistent with the composition of the crystallization agent blend, and the pure flavor is placed in the PEGC domains and released into the wash cycle at a rate consistent with the molecular weight of PEG. Compared to the particles described in, for example, Example 1, the solubility percentage determined by the "Dissolution Test Method" is now independent of the different domains. In addition, relative to Example 3, this format has no restrictions on the absolute amount of SDC domains and PEGC domains in the particles.

[0447] Preparation of SDC domain

[0448] Mixing - Place a 250 ml stainless steel beaker (Thermo Fischer Scientific, Waltham, MA.) on a hot plate (VWR, Radnor, PA, 7×7 CER hot plate, catalog number NO97042-690). Add water (Milli-Q Academic) and crystallization agent to the beaker. Place a temperature probe in the composition. Assemble a mixing apparatus including an overhead mixer (IKA Works Inc, Wilmington, NC, model RW20 DMZ) and a three-blade impeller design and place the impeller in the preparation. Set the heater to 80° C., set the impeller to rotate at 250 rpm, and then heat the composition to 80° C., or until all the crystallization agent is dissolved and the composition is clear. The preparation is then poured into a Max 100 Mid cup (Speed ​​Mixer), covered, and allowed to cool to 25° C. The preparation was spun in a Speedmixer (Flack Tek. Inc, Landrum, SC, Model DAC 150.1FVZ-K) at 3000 rpm for 3 minutes to add the fresh feel benefit agents as indicated in the table.

[0449] Forming - The preparation was transferred to a polymer mold patterned with a 5 mm diameter hemisphere. The preparation was then placed in a refrigerator equilibrated to 4°C (VWR Door Solid Lock F refrigerator, 115V, 76300-508, or equivalent) for 8 hours to allow the crystallization agent to crystallize.

[0450] Drying - Place the preparation in a convection oven (Yamato, DKN400 or equivalent) set at 25°C for an additional 8 hours with a steady stream of air to dry the composition. Remove the preparation from the mold when it is completely dry. Confirm that the final SDC has less than 10% moisture by the "Moisture Test Method".

[0451] Preparation of PEGC domain

[0452] Separately, a 250 ml stainless steel beaker (Thermo Fischer Scientific, Waltham, MA.) was placed on a hot plate (VWR, Radnor, PA, 7×7 CER hot plate, catalog number NO97042-690). PEG (materials 8-11) was added to the beaker. A mixing apparatus including an overhead mixer (IKA Works Inc, Wilmington, NC, model RW20 DMZ) and a three-blade impeller design was assembled and the impeller was placed in the preparation. 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. The preparation was placed in a Speedmixer high-speed mixer (Flack Tek. Inc, Landrum, SC, model DAC 150.1FVZ-K) and rotated at a rate of 3000 rpm for 3 minutes to add a fresh feeling benefit agent as indicated in the table. This preparation was used to prepare low water content compositions within 5 minutes of reaching the final temperature.The preparation was transferred to a polymer mold patterned with a 5 mm diameter hemisphere.

[0453] Preparation of low water content compositions

[0454] Within 30 seconds of placing the preparation in the mold, the SDC domains were placed on the liquid PEGC so that the flat side of the SDC was placed on the flat side of the PEGC. The preparation was allowed to cool at 25°C for at least 30 minutes. After the low water content composition was completely cooled, it was removed from the mold. The two domains attached and the resulting particles were spherical, as shown in FIG. Fig.10 As displayed.

[0464] Example 5

[0465] Example 5 demonstrates a low moisture composition consisting of two or more different particles, wherein these particles may contain a combination of SDC domains and PEGC domains as described in the previous example, or may contain only a single SDC domain and PEGC domain with a freshness benefit agent. These non-limiting examples are described later; however, it should be understood that physical blends of such particles to produce low moisture compositions may also include the aforementioned blends.

[0466] Granular composition sample EA-sample EH (Table 9 and Table 10) represents an active granular composition containing a single SDC domain or PEGC domain. Sample EI-sample EQ (Table 11 and Table 12) represents a low-water composition of the present invention consisting of a granular composition. The type and quantity of particles in the low-water composition are expressed as the "dose of the composition", or the typical amount used by consumers in a single wash. When determining the dosage, many considerations are important, including the amount of "spice capsules in the washing liquid" and the amount of "pure spices in the washing liquid" added by the dosage; however, other factors (such as the selection of the composition of the SDC domain or PEGC domain) are also important for delivering the degree of freshness benefits. For example, consumers may prefer an extra-long-lasting freshness on dry fabrics, which may require the addition of about 5 grams to 10 grams of spice capsule dosage in the washing liquid, or alternatively, consumers may prefer a freshness bursting only at the initial friction, which may require the addition of about 0.5 grams to 2 grams of spice capsule dosage in the washing liquid. For example, consumers may prefer a "flash" of freshness when wet fabrics are removed from the washing liquid, which may require about 5 grams to 10 grams of pure spices, or consumers may prefer a subtle, pleasant freshness aftertaste when wet fabrics are removed from the washing liquid, which may only require the addition of about 1 gram to 2 grams of pure spices in the washing liquid. These freshness characteristics are further affected by the dissolution rate of those domains containing freshness benefit agents. Finally, the selection of particles constituting low-water content compositions is also affected by commercial considerations. It is usually more commercially feasible to produce two types of particles and physically mix them in different proportions so that the composition can meet all consumer preferences, rather than using a special method for each consumer. This is generally referred to as "late product differentiation". Some consumers may prefer a dosage containing about 50 grams to 100 grams of bulk compositions, while some e-commerce consumers or consumers who focus on sustainability may prefer a more concentrated and compact dosage of about 10 grams to 20 grams. Finally, these embodiments provide a series of freshness performances and business opportunities.

[0489]

[0490] Example 6 Example 6 presents compositions prepared from a specific blend of fatty acid materials that are neutralized into an SDC composition and blended with a PEGC composition to produce a solid soluble composition wherein the SDC domains (e.g., Figure 4A , Figure 4B and Figure 4C ) and PEGC domains have different dissolution rate profiles, allowing for different ranking of actives within each domain at specific times in the wash cycle. The dissolution rate of SDC is affected by the percentage of slow crystallizer (% Slow CA), with those with higher percentage levels (e.g., sample EU) dissolving more slowly than those with lower percentage levels (e.g., sample ER). The absolute dissolution rates at different temperatures were determined by the "Dissolution Test Method". The dissolution rate of PEGC is affected by the molecular weight of PEG, such that sample ER (e.g., PEG 10,000) dissolves more slowly than sample ES (e.g., PEG 8,000), which in turn dissolves more slowly than sample ET and sample EU (e.g., PEG 6,000). The absolute dissolution rates at different temperatures were determined by the "Dissolution Test Method".

[0491] Preparation of SDC domain

[0492] mix - Place a 250 ml stainless steel beaker (Thermo Fischer Scientific, Waltham, MA.) on a hot plate (VWR, Radnor, PA, 7×7 CER hot plate, catalog number NO97042-690). Add water (Milli-Q Academic) and crystallization agent to the beaker. Place a temperature probe in the composition. Assemble a mixing apparatus including an overhead mixer (IKA Works Inc, Wilmington, NC, model RW20 DMZ) and a three-blade impeller design and place the impeller in the preparation. Set the heater to 80° C., set the impeller to rotate at 250 rpm, and then heat the composition to 80° C., or until all the crystallization agent is dissolved and the composition is clear.

[0493] Forming - The preparation was then poured into a Max 100 Mid cup (Speed ​​Mixer), covered with a lid, and allowed to cool to 25°C. The preparation was placed in a Speedmixer high-speed mixer (Flack Tek. Inc, Landrum, SC, model DAC150.1FVZ-K) and rotated at a rate of 3000 rpm for 3 minutes to add a fresh feeling benefit agent as indicated in the table. In one non-limiting embodiment, the preparation is transferred to a polymer mold patterned with a 5 mm diameter hemisphere. In another non-limiting embodiment, the preparation is sprayed through an orifice to produce small droplets. The size and shape of the DSC domain are formed to meet the requirements of the final structure of the final low water content composition (e.g., Figure 7 , Figure 8 , Fig. 9 and Fig.10 The preparation is then placed in a refrigerator (VWR Door Solid Lock F refrigerator, 115V, 76300-508, or equivalent) equilibrated to 4°C for 8 hours to allow the crystallization agent to crystallize.

[0494] Drying - Place the preparation in a convection oven (Yamato, DKN400 or equivalent) set at 25°C for an additional 8 hours with a steady stream of air to dry the composition. Remove the preparation from the mold when it is completely dry. Confirm that the final SDC has less than 10% moisture by the "Moisture Test Method".

[0495] Preparation of PEGC domain

[0496] Separately, a 250 ml stainless steel beaker (Thermo Fischer Scientific, Waltham, MA.) was placed on a hot plate (VWR, Radnor, PA, 7×7 CER hot plate, catalog number NO97042-690). PEG (materials 8-11) was added to the beaker. A mixing apparatus including an overhead mixer (IKA Works Inc, Wilmington, NC, model RW20 DMZ) and a three-blade impeller design was assembled and the impeller was placed in the preparation. 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. The preparation was placed in a Speedmixer high-speed mixer (Flack Tek. Inc, Landrum, SC, model DAC 150.1FVZ-K) and rotated at a rate of 3000 rpm for 3 minutes to add a fresh feeling benefit agent as indicated in the table. In one non-limiting example, the preparation is used to prepare a low water content composition within 5 minutes after reaching the final temperature. In one non-limiting embodiment, the preparation is transferred to a polymer mold patterned with a 5 mm diameter hemisphere. The size and shape of the DSC domain are formed to meet the requirements of the final structure of the final low water content composition (e.g., Figure 7 , Figure 8 , Fig. 9 and Fig.10 ).

[0497] Preparation of low water content compositions

[0498] The sample ER (5 mg)-SDC composition was sprayed onto the plate in small droplets, crystallized, and then dried. PEGC was sprayed onto the plate and allowed to crystallize. The two plates were combined to produce low water content composition particles (e.g., Fig.10 ). The sample ES (5 mg)-SDC composition was sprayed onto a plate in small droplets, crystallized, and then dried. PEGC was sprayed onto the surface of the SDC composition to allow it to crystallize. The low-water composition was a coated particle (e.g., Figure 8 ). The sample ET (500 mg)-PEGC composition was placed on a plate as a large droplet, crystallized and then dried. SDC was sprayed to produce fine particles, which attached to the surface of the large droplet. The low-water composition was a sugar-gum-droplet-like particle (e.g., Fig. 9 ). Sample EU (500 mg)-SDC composition was spray dried small particles. Small SDC particles were added to the PEGC melt and large droplets were placed on a flat surface to allow crystallization. The low water content composition encapsulated the SDC (e.g. Figure 7 ).

[0499] Without limitation, the final low moisture composition for laundry treatment may contain particles including one of the combinations of particles described in Sample ER, Sample ES, Sample ET and Sample EU.
