Description

[Technical Field]

[0001] The present invention relates to compositions for the controlled release of meristems. In particular, the present invention relates to compositions comprising a water-soluble matrix and a meristem at least partially encapsulated in core-shell microcapsules comprising a core and a shell surrounding the core. The present invention also relates to methods for making the compositions defined herein, consumer products comprising the compositions defined herein, and the use of compositions and consumer products for improving the perception or enhancing the performance of meristems in consumer products. [Background technology]

[0002] Background of the present invention Developing consumer products that optimize long-term exposure of receptor sites to effective levels of beneficial agents, such as home care, personal care, and fabric care products, is a major challenge. Several studies have shown that beneficial agents are perceived as more effective when they are available at the target site at a individually customized level at a specific time. This challenge can be addressed by utilizing encapsulated beneficial agents.

[0003] The incorporation of encapsulated beneficial agents into consumer products such as home care, personal care, fabric care, and pet care products is well known. Beneficial agents include, for example, fragrances, cosmetics, food ingredients, nutraceuticals, drugs, and substrate enhancers.

[0004] Beneficial agents are encapsulated for a variety of reasons. Microcapsules can separate and protect such materials from external suspension media, such as consumer product bases, where they might be incompatible or unstable. They are also used to help deposit beneficial agents onto substrates such as skin, hair, fabrics, or hard household surfaces. They also function as a means of controlling the spatiotemporal release of beneficial agents.

[0005] Spray drying is a well-known technique for encapsulating active ingredients. Such spray-dried compositions are typically prepared from an emulsion of the beneficial agent to be encapsulated, which is sprayed into a drying chamber. In this process, biopolymers with surface-active properties are commonly used as emulsifiers, which form a water-soluble matrix during spray drying, encapsulating the beneficial agent within it.

[0006] Such spray-dried compositions offer a simple manufacturing process and provide a powder form with the benefits of a pleasant odor. Furthermore, as modern consumers become increasingly environmentally and resource-conscious, these encapsulated products are becoming even more appealing as they are often based on bio-derived materials. Thus, spray-dried compositions have a low environmental impact and enable highly efficient encapsulation of beneficial agents. They also exhibit beneficial release properties. [Overview of the project]

[0007] It is important to control the release of beneficial agents in consumer products at the desired location and rate. For example, if the consumer product is a fabric care product, it is desirable to provide the perception of beneficial agents such as fragrance throughout the entire wash and rinse cycle, from the moment the fabric is removed from the washing machine, during drying, and even after the fabric is dry.

[0008] Such release profiles are achieved by combining a free, unencapsulated fragrance enhancer with an encapsulated fragrance enhancer, where the unencapsulated fragrance essentially contributes to enhancing fragrance perception on wet fabrics, while the encapsulated fragrance essentially contributes to enhancing fragrance perception on dry fabrics. In addition, the encapsulated fragrance may be released during fabric handling, typically under the action of mechanical forces. Core-shell microcapsules may be used, where the core contains the encapsulated fragrance and is surrounded by an impermeable, fragile shell.

[0009] For example, WO2018 / 172514 relates to a composition comprising a solid carrier and a granular powder containing particles with a low fragrance loading, which is employed as a solid fragrance booster. A low fragrance loading was determined to be necessary to avoid breakage during a manufacturing process that requires high shear and to provide stability against leakage. However, a composition employing a higher benefit agent loading would be able to provide consumers with an enhanced perception of the benefit agent. The present invention solves the above disadvantages.

[0010] Summary of the Invention In a first aspect, the present invention provides a composition comprising: a) a water-soluble matrix; and b) a benefit agent at least partially encapsulated in a core-shell microcapsule comprising a core and a shell surrounding the core; wherein the composition comprises from about 54 wt% to about 85 wt%, optionally between about 55 wt% and about 75 wt%, preferably about 55 wt% of the benefit agent based on the total dry weight of the composition.

[0011] In a further aspect, the present invention provides a method for preparing the composition described herein. The present invention further provides a consumer product comprising the composition described herein. The use of the composition and consumer product described herein for improving the perception or enhancing the performance of a benefit agent in a consumer product is provided in a further aspect.

Mode for Carrying Out the Invention

[0012] Definitions The term "benefit agent" refers to a substance that, when added to a product, may improve the consumer's perception of the product or enhance the action of this product in an application. Examples of benefit agents include perfume or fragrance components, cosmetic components, bioactive agents (such as bactericides, insect repellents, and pheromones), substrate enhancers (such as silicones and whitening agents), enzymes (such as lipase and protease), dyes, pigments, and nutraceuticals.

[0013] According to the present invention, an "encapsulated" benefit agent refers to a benefit agent encapsulated in a core-shell microcapsule. Conversely, according to the present invention, an "unencapsulated benefit agent" refers to a benefit agent simply confined (or dispersed) within a water-soluble matrix and not encapsulated in a core-shell microcapsule.

[0014] The term "solid" indicates that the material is in an aggregated solid state at a temperature below about 40°C. The term "water-soluble" indicates that the material completely dissolves in water at a temperature higher than about 10°C. The term "post-rub intensity" refers to the intensity of the fragrance released when the core-shell microcapsule ruptures.

[0015] In the context of the present invention, unless otherwise indicated, all percentages refer to weight percentages (% w / w). Dv50 or Dv(50) represents the maximum particle diameter at which 50% of the volume of the sample is present and is also known as the median particle size by volume. It is also known as the "volume-weighted distribution" or the median of the Malvern volume-weighted particle size distribution and is generally measured using light scattering methods. In the context of the present invention, "dry weight" refers to the weight of the composition after moisture has been removed by spray drying.

[0016] Detailed description Herein, preferred and / or optional features of the present invention are described. Unless otherwise required by context, any aspect of the present invention may be combined with any other aspect of the present invention. Unless otherwise required by context, any preferred or optional feature of any aspect may be combined with any aspect of the present invention, as well as any other preferred or optional feature, either alone or in combination.

[0017] The applicant has surprisingly and unexpectedly discovered a composition comprising the following: a) Water-soluble matrix; and b) A beneficial agent at least partially encapsulated in a core-shell microcapsule comprising a core and a shell surrounding the core; Herein, we can provide a composition containing between approximately 54 wt% and approximately 85 wt% of the enriching agent based on the total dry weight of the composition, such a composition can provide an improved perception of the enriching agent when used in consumer products, compared to compositions containing a smaller amount of the enriching agent.

[0018] The present invention therefore provides a composition comprising: a) Water-soluble matrix; and b) A beneficial agent at least partially encapsulated in a core-shell microcapsule comprising a core and a shell surrounding the core; Here, the composition contains a profit agent in an amount between approximately 54 wt% and approximately 85 wt% based on the total dry weight of the composition.

[0019] Water-soluble polymer matrix The water-soluble polymer matrix may include at least one material selected from the group consisting of starch, particularly water-soluble modified starch, maltodextrin, mannitol, chitosan, gum arabic, arginate, cellulose, pectin, gelatin, polyvinyl alcohol, and mixtures thereof. The resulting encapsulated beneficial agents are easy to manufacture and cost-effective. Furthermore, they are prepared from naturally derived materials that are non-toxic and biodegradable. Thus, such encapsulated agents become more appealing to consumers.

[0020] If the starch is a water-soluble modified starch, such starch can be made from unprocessed starch or pregelatinized starch. It can be derived from tubers, legumes, cereals and grains, such as corn starch, wheat starch, rice starch, waxy corn starch, oat starch, cassava starch, waxy barley starch, waxy rice starch, glutinous rice starch, amyoca starch, potato starch, tapioca starch, and mixtures thereof.

[0021] Water-soluble modified starch may be selected from the group consisting of bleached starch, hydroxypropylated starch, hydroxypropylated phosphate cross-linked starch, hydroxypropylated glycerol cross-linked starch, acetylated phosphate cross-linked starch, acetic acid starch esterified with acetic anhydride, acetic acid starch esterified with vinyl acetate, acetylated adipic acid cross-linked starch, acetylated glycerol cross-linked starch, sodium octenyl succinate starch, and mixtures thereof.

[0022] Water-soluble modified starches possess emulsifying and emulsion-stabilizing capabilities. Due to the hydrophobic properties of the starch modifier, they have the ability to encapsulate droplets of beneficial agents in the form of water-in-oil emulsions. The modified starches described herein provide numerous advantages, including high emulsifying and encapsulating properties when the composition is dried, low viscosity even with high solids content, and excellent oxidation resistance, thereby ensuring good preservation of fragrances and / or cosmetics and stabilization of sensitive ingredients.

[0023] If the water-soluble matrix contains water-soluble modified starch, it may further contain a material selected from the group consisting of maltodextrin, mannitol, and mixtures thereof. Both maltodextrin and mannitol increase the glass transition temperature of the matrix. Furthermore, maltodextrin also acts as a film-forming agent when dried.

[0024] Maltodextrins are characterized by their dextrin equivalents (DE). The higher the DE, the lower the molecular weight of the maltodextrin. In the context of this invention, combining maltodextrins with different DEs may provide optimized encapsulation properties. While not bound by any theory, mixtures of low-DE and high-DE maltodextrins are thought to improve the packing of water-soluble matrices when the composition is dried, for example, by spray drying.

[0025] In addition to the materials described above, the water-soluble matrix may further include hemicellulose. In the context of the present invention, the term "hemicellulose" is understood as a polysaccharide selected from the group consisting of glucans, in particular xyloglucan; mannans, in particular glucomannan; and xylans, in particular arabinoxylan and glucuronoxylan. It has been found that the addition of hemicellulose to water-soluble matrices, particularly starch matrices, leads to a modification of the matrix after drying, improving its release properties under moisture.

[0026] Hemicellulose is preferably xyloglucan, particularly xyloglucan obtainable from tamarind seeds. Xyloglucan is the most abundant hemicellulose in the primary cell walls of non-grass plants, often containing 20 wt.-% of the dry mass of the cell wall. Xyloglucan has a back chain composed of 1,4-linked β-D-glucose residues. Up to 75% of the residues in the back chain are substituted at the C6 position with monosaccharide, disaccharide, or trisaccharide side chains. Preferably, the hemicellulose is xyloglucan obtainable from tamarind seeds, particularly xyloglucan obtained from tamarind seeds, which is also known as "tamarind kernel powder" or "tamarind gum." In tamarind gum, the side chain consists of one or two α-D-xylopyranosyl units, which are optionally capped with β-D-galactopyranosyl, α-L-arabinofuranosyl, or β-D-xylopyranosyl.

[0027] In one embodiment, the water-soluble matrix is ​​in powder form. Spray drying is a well-known technique for encapsulating fragrances or perfumes. Such spray-dried fragrance compositions are generally prepared from an emulsion of the fragrance to be encapsulated, which is sprayed into a drying chamber. In this process, biopolymers with surface-active properties are commonly used as emulsifiers, which form a water-soluble matrix during spray drying, within which the fragrance is encapsulated. Such spray-dried compositions are simple to produce and offer a form of powdered fragrance exhibiting good odor benefits.

[0028] Core-shell microcapsules In the context of the present invention, the beneficial agent is at least partially encapsulated in a core-shell microcapsule comprising a core and a shell surrounding the core. Such compositions enable the release of beneficial agents, for example, in deodorant or antiperspirant applications, either through mechanical action or water-mediated activation. However, such compositions are also particularly useful when employed as beneficial agent delivery means in consumer products that require core-shell microcapsules to adhere to the substrate to which they are applied, such as laundry detergents, in order to deliver optimal benefits.

[0029] The composition of the meristem encapsulated in the core-shell microcapsule and the composition of the meristem not encapsulated in the core-shell microcapsule may be the same or different. This results in modulated release of the same or different meristem components, depending on whether the capsule material is exposed to moisture or mechanical stress. In particular, sequential release of meristem components is anticipated.

[0030] In the context of the present invention, the shell of the core-shell microcapsule may contain a polymer selected from the group consisting of melamine-formaldehyde polymer, urea-formaldehyde polymer, polyurea, polyurethane, polyamide, polyacrylate, polycarbonate, and mixtures thereof.

[0031] thermosetting resin Core-shell microcapsules with a melamine-formaldehyde resin shell have been proven to be particularly suitable for encapsulating fragrances. These are described in the prior art, for example, in WO2008 / 098387A1, WO2016 / 207180A1, WO2017 / 001672A1, and WO2018 / 197266A1.

[0032] A preferred example of a core-shell microcapsule includes a shell surrounding a core, wherein the shell includes a network of crosslinked resins, wherein the resins include a triple copolymer and a polymeric stabilizer, wherein the triple copolymer includes a portion derived from at least one polyamine, a portion derived from a milk protein or milk protein derivative, and a portion derived from the group consisting of alkylene and alkylene oxy portions having 1 to 6 methylene units.

[0033] Furthermore, core-shell microcapsules with polyurea or polyurethane polymer shells have also been successfully used for encapsulating fragrances. They have the advantage of addressing consumer concerns regarding residual formaldehyde in compositions. Such capsules are also described in the prior art, for example, in WO2016 / 071151A1 and WO2019 / 174978A1.

[0034] In one embodiment, the shell comprises a thermosetting resin formed by the reaction of a polyfunctional amine containing at least one amino group with at least one polyfunctional isocyanate, wherein the shell comprises a cationic polymer containing a quaternary ammonium group, wherein the shell further comprises a polymeric stabilizer containing a completely or partially dissociated carboxylic acid group, such as that described in WO2023 / 017014A1.

[0035] Core-shell microcapsules, with a shell made of polyacrylate, i.e., one or more monoethylenically unsaturated and / or polyethylenically unsaturated monomers (one or more) in polymer form, have also been successfully used for encapsulating fragrances. Such capsules are described in the prior art, for example, in WO2013 / 111912A1 or WO2014 / 032920A1.

[0036] In one embodiment, the core-shell microcapsule comprises a shell made of a thermosetting resin formed by the reaction of a shell-forming monomer containing a polyamine and a material containing multiple olefinic double bonds that enable reaction with the polyamine, such as those described in WO2019 / 121738A1.

[0037] Polymeric stabilizers In one embodiment, the shell comprises a thermosetting resin formed by the reaction of a shell-forming material selected from monomers, prepolymers and / or precondensates, and also comprises a polymeric surfactant and a polymeric stabilizer containing a functional group that enables the formation of a covalent bond with the shell, such as that described in WO2019 / 121736A1.

[0038] In one embodiment, the shell may include a polymeric stabilizer formed by a combination of a polymeric surfactant and at least one aminosilane. The polymeric surfactant includes polysaccharides containing carboxylic acid groups. The aminosilane is as defined hereafter herein. The shell may further include polysaccharides, preferably polysaccharides containing beta(1→4) linked monosaccharide units, more preferably cellulose derivatives, particularly selected from the group consisting of hydroxyethylcellulose, hydroxypropylmethylcellulose, cellulose acetate, carboxymethylcellulose and combinations thereof, and preferably hydroxyethylcellulose. Such capsules are described in the prior art, for example, WO2020 / 233887A1.

[0039] Hydrated polymer phase and polymeric stabilizer In one embodiment, the shell may include a hydrated polymer phase and a polymeric stabilizer at the interface between the shell and the core. In this configuration, the polymeric stabilizer provides an impermeable encapsulation material, while the hydrated polymer phase provides the desired deposition and adhesion to the substrate. Furthermore, although not bound by any theory, it is presumed that the hydrated polymer phase also provides an optimal site for microbial degradation.

[0040] The polymeric stabilizer may be selected from a wide range of film-forming materials and resins. Preferably, the polymeric stabilizer is highly crosslinked to significantly reduce the diffusion of the encapsulated benefiting agent through the shell. Preferably, the impermeability of the shell is sufficiently high to significantly prevent leakage of the benefiting agent into the extraction base, such as in consumer products containing surfactants.

[0041] In one embodiment of the present invention, the polymeric stabilizer is a thermosetting resin. Thermosetting resins are typically obtained by reacting polyfunctional monomers such as amines, isocyanates, alcohols, or phenols, chlorocarboxylic acids, (meth)acrylates, epoxides, silanes, and aldehydes.

[0042] In one embodiment of the present invention, a polymeric stabilizer is formed by the reaction of an aminosilane with a polyfunctional isocyanate. Such a polymeric stabilizer has the advantage of readily providing surface anchor groups that are highly crosslinked and can be used to immobilize additional materials to complete shell formation. These additional materials may include additional encapsulating materials, coatings, and simple and composite coacervates and hydrogels, as described in more detail below.

[0043] The aminosilane used in the formation of polymeric stabilizers can be selected from the compounds of formula (I). Si(R 1 )(R 2 ) f (OR 3 ) (3-f) Equation (I) In the formula, R 1is a linear or branched alkyl or alkenyl residue containing an amine functional group; R 2 is each independently a linear or branched alkyl group having 1 to 4 carbon atoms; R 3 is each independently H, or a linear or branched alkyl group having 1 to 4 carbon atoms; and f is 0, 1 or 2.

[0044] The silane groups may undergo polycondensation reactions with each other to form a silica network at this interface that further stabilizes the oil / water interface. In one embodiment, R 2 and R 3 are each independently methyl or ethyl. In one embodiment, f is 0 or 1.

[0045] In one embodiment, R 1 is a linear or branched alkyl or alkenyl residue of C1 - C 12 containing an amine functional group. Optionally, R 1 is a linear or branched alkyl or alkenyl residue of C1 - C4 containing an amine functional group. In one embodiment, the amine functional group is a primary amine, secondary amine or tertiary amine.

[0046] In one embodiment, at least one aminosilane is a bipodal aminosilane. A "bipodal aminosilane" means a molecule containing at least one amino group and two residues, each of those residues having at least one alkoxysilane moiety. Bipodal aminosilanes are particularly advantageous for forming a stable oil / water interface. Without wishing to be bound by theory, this beneficial role is thought to be due to the specific bi - directional arrangement of the silane moieties in the molecule of the bipodal aminosilane, which enables the formation of a more tightly linked silica network at the oil / water interface.

[0047] In one embodiment, the bipodal aminosilane is a compound of formula (II). (OR 3 ) (3-f) (R 2 ) f Si-R 4 -XR 4 -Si(OR 3 ) (3-f) (R 2 ) f Formula (II) In the formula, X is -NR 5 -, -NR 5 -CH2-NR 5 -, -NR 5 -CH2-CH2-NR 5 -, -NR 5 -CO-NR 5 -,or [ka] And, R 2 Each of these is independently a linear or branched alkyl group having 1 to 4 carbon atoms; R 3 Each of these is independently a linear or branched alkyl group having H or 1 to 4 carbon atoms; R 4 Each of these is an independent linear or branched alkylene group having 1 to 6 carbon atoms; R 5 Each of these is independently H, CH3, or C2H5; and f is independently 0, 1, or 2.

[0048] In one embodiment, R 2 It is either CH3 or C2H5. In one embodiment, R 3 It is either CH3 or C2H5. In one embodiment, R 4 These are -CH2-, -CH2-CH2-, or -CH2-CH2-CH2-CH2-. In one embodiment, R 5 It is either H or CH3. In one embodiment, f is 0 or 1.

[0049] Suitable examples of bimodal aminosilanes include, but are not limited to, bis(3-(triethoxysilyl)propyl)amine, N,N'-bis(3-(trimethoxysilyl)propyl)urea, bis(3-(methyldiethoxysilyl)propyl)amine, N,N'-bis(3-(trimethoxysilyl)propyl)ethane-1,2-diamine, bis(3-(methyldimethoxysilyl)propyl)-N-methylamine, N,N'-bis(3-(triethoxysilyl)propyl)piperazine, and combinations thereof.

[0050] In one embodiment, the bimodal aminosilane is a bis(3-(triethoxysilyl)propyl)amine, which has the advantage of releasing ethanol instead of the more toxic and undesirable methanol during the polycondensation of the ethoxysilane group.

[0051] Bimodal aminosilanes can be secondary aminosilanes. Using secondary bimodal aminosilanes instead of primary aminosilanes reduces the reactivity of polymeric stabilizers to electrophilic species, particularly aldehydes. Therefore, ferriants containing high levels of aldehydes can be encapsulated with a lower tendency towards adverse interactions between the core-forming material and the shell-forming material. Other aminosilanes can also be used in combination with the bimodal aminosilanes mentioned above, particularly the aminosilanes described herein.

[0052] Polyfunctional isocyanates may be selected from organic isocyanates in which the isocyanate group is bonded to an organic residue (RN=C=O or R-NCO). Polyfunctional isocyanates may be selected from alkyl, alicyclic, aromatic, alkyl-aromatic, and anionic modified polyfunctional isocyanates having two or more (e.g., three, four, five, etc.) isocyanate groups in the molecule, as well as combinations thereof.

[0053] Preferably, the polyfunctional isocyanate is an aromatic or alkyl aromatic isocyanate, and the alkyl aromatic polyfunctional isocyanate preferably has a methyl isocyanate group attached to the aromatic ring. Both aromatic and methyl isocyanate-substituted aromatic polyfunctional isocyanates exhibit superior reactivity compared to alkyl and alicyclic polyfunctional isocyanates. Among these, 2-ethylpropane-1,2,3-tolyltris((3-(isocyanatemethyl)phenyl)carbamate) is particularly preferred due to its trifunctional properties favorable for the formation of intermolecular crosslinks and its intermediate reactivity favorable for network uniformity. This alkyl aromatic polyfunctional isocyanate is commercially available under the trademark Takenate D-100 N, sold by Mitsui, or under the trademark Desmodur® Quix175, sold by Covestro.

[0054] As an alternative to aromatic or alkyl-aromatic polyfunctional isocyanates, the addition of anionically modified polyfunctional isocyanates may be advantageous due to their ability to react at the oil / water interface, and even in the aqueous phase near the oil / water interface. Particularly preferred anionically modified polyfunctional isocyanates have formula (III). [ka] Formula (III) shows a commercially available anionically modified polyisocyanate, which is a modified isocyanurate of hexamethylene diisocyanate sold by Covestro under the trademark Bayhydur® XP2547.

[0055] In a preferred embodiment of the present invention, the polyfunctional isocyanate is 2-ethylpropane-1,2,3-tolyltris((3-(isocyanatomethyl)phenyl)carbamate). Particularly preferably, the polymeric stabilizer is formed by the reaction of bis(3-(triethoxysilyl)propyl)amine with 2-ethylpropane-1,2,3-tolyltris((3-(isocyanatomethyl)phenyl)carbamate). This particular combination of bimodal secondary aminosilane and polyfunctional isocyanate provides advantageous interfacial stability and release properties. The stabilized interface is sufficiently impermeable to effectively encapsulate at least one beneficial agent contained in the core and has the desired surface functional groups.

[0056] In one embodiment, the shell may be as described in WO2020 / 207849A1. In a preferred embodiment of the present invention, the hydrated polymer phase may be a coacervate, particularly a composite coacervate. "Composite coacervation" refers to the formation of an interfacial layer containing a mixture of polymer electrolytes.

[0057] The phenomenon of coacervation can be observed under an optical microscope, where it is most evident by the appearance of a ring around the droplet of the core composition. This ring consists of the aforementioned polymer electrolyte-rich phase, which has a different refractive index from the surrounding aqueous phase.

[0058] Coacervation of polymer electrolytes is generally induced by bringing the polymer electrolyte closer to its isoelectric point, that is, the point where the net charge of the polymer electrolyte is zero or close to zero. This can be achieved by changing the salt concentration or pH of the medium. In composite coacervation, composite formation occurs at a pH where one polymer electrolyte has an overall positive charge (polycation) and the other polymer electrolyte has an overall negative charge (polyanion), so the overall charge of the composite is neutral.

[0059] In a preferred embodiment of the present invention, the coacervate may be formed from polycations and polyanions. In one embodiment, the shell may comprise a complex coacervate formed from at least one protein and at least one polysaccharide. Such core-shell capsules have been proven suitable for encapsulating beneficial agents and are described, for example, in WO1996 / 020612A1, WO2001 / 03825A1 or WO2015 / 150370A1.

[0060] Preferably, pH is used as a parameter to drive coacervation. Therefore, the polycation preferably has a pH-dependent charge. This is the case for polymers with primary, secondary, and tertiary amino groups, such as polyamines, e.g., chitosan, and most proteins, e.g., gelatin. Proteins have the additional advantage of being prone to temperature-dependent structural changes, which can also be used to control the morphology of the coacervate. In particular, by changing the temperature of some proteins, the formation of secondary, tertiary, and quaternary structures of the protein can be induced, which can also be used to control the properties of the coacervate.

[0061] Chitosan has the advantage of being derived from chitin, a natural polymer. In preferred embodiments of the present invention, the polycation is selected from the group consisting of proteins, chitosan, and combinations thereof.

[0062] More specifically, the polycation may be a protein selected from the group consisting of gelatin, casein, albumin, polylysine, soy protein, pea protein, rice protein, hemp protein, potato protein, and combinations thereof.

[0063] In a particularly preferred embodiment of the present invention, at least one protein is gelatin, more preferably type B gelatin, or potato protein. Type B gelatin is obtained from the alkali treatment of collagen and is well known for its ability to form complexes with anionic polyelectrolytes such as negatively charged polysaccharides under weakly acidic conditions.

[0064] Gelatin is typically characterized by its so-called "Bloom Strength." In the context of this invention, Bloom Strength refers to the stiffness of a gelatin film as measured by a so-called "Bloom Gelometer," according to Chapter 2.1 of the Official Procedure of the American Gelatin Manufacturers Association (revised 2019). According to this procedure, Bloom Strength (expressed in Bloom) is equal to the weight (expressed in grams) required to vertically move a standardized plunger with a diameter of 12.5 mm to a depth of 4 mm into a gelatin gel prepared under controlled conditions (i.e., by dissolving 6.67 wt.-% gelatin in deionized water at 60°C in a standardized jar and allowing the gel to form at 10°C for 17 hours). A higher weight indicates a higher Bloom Strength of the gelatin used to prepare the gel tested.

[0065] In a preferred embodiment of the present invention, type B gelatin has a bloom intensity of 90 to 250. If the bloom strength is too low, the gel will be mechanically weak, and the resulting coacervate may not form a self-supporting layer of gelatin-rich phase around the core composition. If the bloom strength is too high, the coacervate and the resulting gelatin-rich phase may become too brittle.

[0066] In a preferred embodiment of the present invention, type B gelatin is obtained from fish because fish gelatin is more readily accepted by consumers than beef or pork gelatin, mainly due to health concerns, social contexts, or religious regulations. Alternatively, the protein may be plant-based protein, particularly pea protein, potato protein, and / or soy protein, which have the advantage of being vegan.

[0067] Polycations may also be denatured proteins. In contrast to native proteins, denatured proteins are essentially amorphous, deprived of the ability to form secondary, tertiary, or quaternary structures. Such amorphous proteins can form more impermeable films compared to native proteins and thus can also contribute to the encapsulation ability of the shell. Denaturation may be achieved by treating the protein with chemical or physical means such as acid or alkali treatment, heat, or exposure to hydrogen bond disruptors.

[0068] When the polycation is chitosan, the chitosan can have a molecular weight between 3,000 and 1,000,000 g / mol, more specifically between 10,000 and 500,000 g / mol, and even more specifically between 30,000 and 300,000 g / mol.

[0069] The polyanion may be any negatively charged polymer. However, since pH is preferably used to control coacervation, it may be more advantageous for the polymer's charge to be pH-dependent. Such polymers may be selected from polymers having pendant carboxyl groups, such as polymers and copolymers of methacrylic acid and acrylic acid, hydrolyzed maleic anhydride copolymers, and polysaccharides having carboxyl groups.

[0070] In a preferred embodiment of the present invention, the polyanion is a polysaccharide containing a carboxylate group and / or a sulfate group.

[0071] Polysaccharides containing carboxylate groups are particularly suitable for complex coacervation with proteins. This is because the net charge of these polysaccharides can be adjusted by adjusting the pH, thereby promoting complexation with amphoteric electrolytic proteins. Complexation occurs at a pH where the protein is positively charged overall and the polysaccharide is negatively charged overall, thereby neutralizing the overall charge of the complex. These polysaccharides include native polysaccharides, i.e., polysaccharides that have not been modified from nature, and modified polysaccharides.

[0072] Polysaccharides containing carboxylic acid groups may contain uronic acid units, particularly hexuronic acid units. Such polysaccharides are widely available in nature. The hexuronic acid unit is selected from the group consisting of galacturonic acid units, glucuronic acid units, particularly 4-O-methyl-glucuronic acid units, glucuronic acid units, mannuronic acid units, and combinations thereof.

[0073] Polysaccharides containing carboxylic acid groups may be branched. Branched polysaccharides containing carboxylic acid groups have the advantage of forming a more compact network than linear polysaccharides, which can be advantageous for the impermeability of the encapsulation shell, resulting in reduced leakage and higher encapsulation efficiency.

[0074] The carboxylate group can be present, at least partially, in the form of the corresponding carboxylate salt, particularly the corresponding sodium, potassium, magnesium, or calcium carboxylate salt.

[0075] In certain embodiments of the present invention, the polyanion is selected from the group consisting of pectin, gum arabic, arginate, and combinations thereof. In pectin, carboxylic acid groups can be partially present in the form of their corresponding methyl esters. The percentage of carboxylic acid groups present in the form of their corresponding methyl esters may be 3% to 95%, preferably 4% to 75%, and more preferably 5% to 50%. Pectin containing 50% or more carboxyl groups present in the form of their corresponding methyl esters is referred to as "highly methoxylated." Pectin containing less than 50% carboxylic acid groups present in the form of their corresponding methyl esters is referred to as "lowly methoxylated."

[0076] Of the two variants of gum arabic, namely Acacia Senegal rubber and Acacia Seyal rubber, Acacia Senegal rubber is preferred because it contains a higher level of glucuronic acid.

[0077] The hydrated polymer phase can be a hydrogel. In the context of the present invention, "hydrogel" is a three-dimensional (3D) network of hydrophilic polymers that can swell in water while maintaining its structure due to chemical or physical crosslinking of individual polymer chains.

[0078] Such hydrogels can be formed by several methods, including the self-assembly of polyelectrolytes at the interface, particularly around existing interfaces; covalent grafting of pre-formed hydrogel particles in solution; polymerization of water-soluble monomers initiated at the interface; and phase separation of water-soluble polymers at the interface. To avoid ambiguity, in the context of this invention, coacervates, particularly complex coacervates, that are crosslinked by covalent bonds are considered hydrogels.

[0079] The applicant has found that the use of hydrogels particularly enhances both the deposition and adhesion of microcapsules on substrates, especially on fabrics. Hydrogels can be interconnected with polymeric stabilizers, particularly through functional groups present on the surface of these stabilizers.

[0080] This allows for the creation of a shell composed of polymer composites, instead of a blend alone, by locking a hydrogel layer onto a polymeric stabilizer present at the droplet interface. Both hydrogel crosslinking and hydrogel interconnection with polymeric stabilizers can be performed sequentially or simultaneously.

[0081] In a preferred embodiment of the present invention, the hydrogel is a complex coacervate crosslinked with a crosslinked coacervate, particularly a polyfunctional aldehyde, more specifically a bifunctional aldehyde selected from the group consisting of succinaldehyde, glutaraldehyde, glyoxal, benzene-1,2-dialdehyde, benzene-1,3-dialdehyde, benzene-1,4-dialdehyde, piperazine-N,N-dialdehyde, 2,2'-bipyridyl-5,5'-dialdehyde, and combinations thereof. Bifunctional aldehydes are known as effective crosslinking agents for proteins.

[0082] WO2021 / 239742A1 describes crosslinking at least one protein with a first crosslinking agent, followed by the addition of at least one polysaccharide to form a complex coacervate.

[0083] Hydrogels are temperature-sensitive and can have a gelation temperature particularly between 20°C and 50°C, preferably between 25°C and 40°C. When using such hydrogels, the capsule deposition performance on the fabric can be enhanced when the fabric is washed at a temperature higher than the hydrogel gelation temperature.

[0084] The shell can be further stabilized with a stabilizer. Preferably, the stabilizer contains at least two carboxylic acid groups. More preferably, the stabilizer is selected from the group consisting of citric acid, benzene-1,3,5-tricarboxylic acid, benzene-1,2,4-tricarboxylic acid, 2,5-franzicarboxylic acid, itaconic acid, poly(itaconic acid), and combinations thereof. In one embodiment, the core-shell microcapsule may be as described in WO2023 / 020883A1.

[0085] In one embodiment, the shell comprises a polymeric stabilizer formed by a combination of a polymeric surfactant and at least one aminosilane; a hydrocolloid; and a linker derived from an epoxy resin. The polymeric surfactant and at least one aminosilane are as defined above herein. In one embodiment, the hydrocolloid is selected from the group consisting of polysaccharides such as pectin, modified starch, guar gum, locust bean gum, konjac mannan, acacia gum, guatti gum, tragacanth, agar, arginate, and carrageenan; proteins such as gelatin and potato protein; and combinations thereof. In one embodiment, the epoxy resin is selected from the group consisting of epoxidized vegetable oils, epoxidized alcohols, epoxidized furans, epoxidized phenols, and combinations thereof.

[0086] In one embodiment, the shell comprises first and second polymer electrolytes forming a composite coacervate, wherein the microcapsule comprises at least one interface activating means. In one embodiment, the interface activating means is or derived from a diacid or dialdehyde, such as the shell described in WO2022 / 112204A1.

[0087] In one embodiment, the shell of the microcapsule can be made of a biodegradable or non-biodegradable material. In one embodiment, the microcapsule is made of a biodegradable material.

[0088] In a preferred embodiment of the present invention, the median volume diameter Dv(50) of the multiple core-shell microcapsules is 1 to 100 μm, preferably 5 to 75 μm, more preferably 8 to 60 μm, and even more preferably 10 to 30 μm. Microcapsules having a median volume diameter in the range of 10 to 30 μm exhibit optimal deposition on various substrates such as fabrics and hair.

[0089] The resulting encapsulated composition, presented in the form of a slurry of microcapsules suspended in an aqueous suspension medium, may be directly incorporated into a composition containing a water-soluble matrix, which may optionally contain a beneficial agent encapsulated within it. If necessary, however, the slurry may be dried to present the encapsulated composition in the form of a dry powder. Drying of the microcapsule slurry is conventional and may be carried out according to techniques known in the art, such as spray drying, evaporation, freeze-drying, or the use of a desiccant. Typically, as is conventional in the art, the dried microcapsules are dispersed or suspended in a suitable powder, such as powdered silica, which can function as a bulk agent or flow aid. Such a suitable powder may be added to the encapsulated composition before, during, or after the drying step.

[0090] Combining at least two encapsulation processes has the advantage of providing different mechanisms for releasing functional materials, such as a combination of moisture-induced release and mechanical stress-induced release.

[0091] Profit Agent Suitable beneficial agents for incorporation into the core of the core-shell microcapsules of the present invention include fragrance or scent components, cosmetic components, bioactive agents (such as bactericides, insecticides, and pheromones), substrate enhancers (such as silicones and whitening agents), enzymes (such as lipases and proteases), dyes, pigments, and nutraceuticals.

[0092] In one embodiment, the beneficial agent comprises, optionally, at least one fragrance component.

[0093] A comprehensive list of fragrance components that can be encapsulated according to the present invention can be found in the fragrance literature, for example, “Perfume & Flavor Chemicals”, S. Arctander (Allured Publishing, 1994).

[0096] The aforementioned components are not only biodegradable, but have also been confirmed to be suitable for encapsulation in terms of their physical and chemical properties, such as lipophilicity, molecular size, and reactivity to shell materials. They therefore offer a useful selection of perfume components for easily and reliably providing more sustainable fragrance capsules.

[0097] In one embodiment, the beneficial agent may include at least one fragrance precursor (meaning a material that enables the release of fragrance components by stimulating means such as changes in temperature, the presence of an oxidizing agent, the action of an enzyme, or the action of light). Such fragrance precursors are well known in the art.

[0098] In one embodiment, the beneficial agent may contain at least one functional cosmetic ingredient. The functional cosmetic ingredient for use in the encapsulated composition is preferably hydrophobic. Optionally, the cosmetic ingredient has an octanol / water partition coefficient (ClogP) of 1.5 or greater, and optionally 3 or greater. Alternatively, the ClogP of the cosmetic ingredient is between 2 and 7.

[0099] Particularly useful functional cosmetic ingredients may be selected from the group consisting of emollients, smoothing ingredients, hydrating ingredients, soothing and relaxing ingredients, decorative ingredients, deodorants, anti-aging ingredients, cell rejuvenating ingredients, draining ingredients, remodeling ingredients, skin leveling ingredients, preservatives, antioxidants, antibacterial or bacteriostatic ingredients, cleansing ingredients, lubricating ingredients, structuring ingredients, hair conditioning ingredients, whitening ingredients, texture ingredients, softening ingredients, anti-dandruff ingredients, and exfoliating ingredients.

[0100] Examples of suitable functional cosmetic ingredients include, but are not limited to, the following: hydrophobic polymers such as alkyldimethylsiloxane, polymethylsilsesquioxane, polyethylene, polyisobutylene, styrene-ethylene-styrene and styrene-butylene-styrene block copolymers; mineral oils such as hydrogenated isoparaffin and silicone oil; vegetable oils such as argan oil, jojoba oil, and aloe vera oil; fatty acids and fatty alcohols and their esters; glycolipids; phospholipids; and ceramides. Sphingolipids such as mids; sterols and steroids; terpenes, sesquiterpenes, triterpenes and their derivatives; essential oils such as arnica oil, artemisia oil, bark tree oil, birch leaf oil, calendula oil, cinnamon oil, echinacea oil, eucalyptus oil, ginseng oil, jujube oil, helianthus oil, jasmine oil, lavender oil, lotus seed oil, perilla oil, rosemary oil, sandalwood oil, tea tree oil, thyme oil, valerian oil, absinthe oil, ylang-ylang oil, and yucca oil.

[0101] In particular, at least one functional cosmetic ingredient may be selected from the group consisting of sandalwood oil such as Fusanus Spicatus kernel oil; panthenyl triacetate; tocopheryl acetate; tocopherol; naringinine; ethyl linoleate; farnesyl acetate; farnesol; citronellyl methylcrotonic acid; and ceramide-2 (1-stearoyl-C18-sphingosine, CAS number: 100403-19-8).

[0102] In one embodiment, the beneficial agent may include an agent that suppresses or reduces malodors and their perception by adsorption of odors, an agent that provides a warming or cooling effect, an insecticide, or an ultraviolet absorber.

[0103] In one embodiment, the beneficial agent is completely encapsulated in a core-shell microcapsule comprising a core and a shell surrounding the core. If present, the unencapsulated meristem may be identical or different from the meristem used in the microcapsule compositions described herein. This results in modulated release of the same or different odor impression, depending on whether the capsule material is exposed to moisture or mechanical stress. In particular, sequential release of the meristem is anticipated.

[0104] The compositions of the present invention enable the release of beneficial agents, for example, in deodorant or antiperspirant applications, either through mechanical action or water-mediated activation. However, such compositions are particularly useful when employed as fragrance delivery means in consumer products that require core-shell microcapsules to adhere to a substrate to which they are applied, such as laundry detergents, in order to deliver optimal perfume effect.

[0105] The unencapsulated meristem may preferably contain, and preferably consist of, at least one, preferably at least two, more preferably at least four, even more preferably at least eight, and even more preferably at least sixteen biodegradable components. The biodegradable components may be present at a total concentration of at least 75 wt.-%, preferably at least 80 wt.-%, more preferably at least 85 wt.-%, even more preferably at least 90 wt.-%, and even more preferably at least 95 wt.-%, relative to the total weight of the unencapsulated meristem. The biodegradable components may be selected from the group defined above herein.

[0106] The composition of the present invention contains approximately 54 wt% to approximately 85 wt%, optionally between approximately 55 wt% and approximately 75 wt%, preferably approximately 55 wt%, of the enriching agent based on the total dry weight of the composition. Although prior art has suggested the instability of granular powders containing fragrance loads exceeding 30 wt% dry, the composition of the present invention is nevertheless stable in dry form.

[0107] Even more surprisingly, it has been found that it is advantageous for the composition to contain more than approximately 31 wt% of the encapsulated meristem relative to the total dry weight of the composition. The olfactory performance of compositions containing more than approximately 31 wt% of the encapsulated meristem relative to the total dry weight of the composition has been found to be higher than that of compositions containing less than approximately 31 wt% of the encapsulated meristem.

[0108] In one embodiment, the composition includes: a) A water-soluble matrix comprising approximately 3 wt% to 44 wt%, optionally approximately 36 wt% to 40 wt%, based on the total dry weight of the composition; b) Core-shell microcapsules containing a core and a shell surrounding the core, with a core of approximately 10 wt% to approximately 97 wt%, and optionally between approximately 36.5 wt% and approximately 64 wt%; and c) Unencapsulated fermented agent in a concentration of 0-46 wt% (Based on the total dry weight of the composition). In one embodiment, the shell of the microcapsule comprises a thermosetting resin, particularly a melamine-formaldehyde polymer.

[0109] In one embodiment, the composition includes: - Sodium octenyl succinate starch in an amount between approximately 1 wt% and 35 wt%; - Mannitol between approximately 2 wt% and 9 wt%; - Core-shell microcapsules comprising a core and a shell surrounding the core, with a concentration between approximately 10 wt% and approximately 97 wt%, wherein a beneficial agent is encapsulated within them; and - Unencapsulated profit agent between 0 wt% and approximately 46 wt% (Based on the total dry weight of the composition). In one embodiment, the shell of the microcapsule comprises a thermosetting resin, particularly a melamine-formaldehyde polymer.

[0110] In one embodiment, the composition includes: - Sodium octenyl succinate starch in an amount between approximately 29 wt% and 32 wt%; - Mannitol content between approximately 7 wt% and 8 wt%; - Core-shell microcapsules comprising a core and a shell surrounding the core, with a yielding agent encapsulated within them, between approximately 36.5 wt% and approximately 64 wt%; and - Unencapsulated profit agent between 0 wt% and approximately 26 wt% (Based on the total dry weight of the composition). In one embodiment, the shell of the microcapsule comprises a thermosetting resin, particularly a melamine-formaldehyde polymer. In one embodiment, the composition is provided in solid form.

[0111] Solid carriers In one embodiment, if the composition is in solid form, a solid carrier is further included in the composition. The solid carrier may be any particle, preferably a porous particle suitable for serving as a vehicle for the stimulant on a fabric. In one embodiment, the solid carrier is water-soluble to avoid dyeing the fabric.

[0112] It is known that the risk of explosion increases as the concentration of the beneficial agent in the solid composition increases, especially when it is in powder form. Therefore, by diluting the solid composition with a solid carrier, it is possible to provide a formulation that complies with dust explosion regulations.

[0113] The solid carrier may be selected from the group consisting of inorganic or organic salts or oxides thereof of alkali metals, alkaline earth metals, or transition metals; carbohydrates such as monosaccharides, disaccharides, and polysaccharides and their derivatives; polyethylene glycol (PEG); polyvinylpyrrolidone (PVP); urea; water-soluble organic solid acids; water-soluble fatty alcohols or fatty acids; and mixtures thereof.

[0114] In one embodiment, the solid carrier is selected from the group consisting of sodium chloride, sodium sulfate, sodium acetate, zeolite, sodium carbonate, sodium bicarbonate, clay, talc, calcium carbonate, magnesium sulfate, gypsum, calcium sulfate, magnesium oxide, zinc oxide, titanium dioxide, calcium chloride, potassium chloride, magnesium chloride, zinc chloride, and combinations thereof. In one embodiment, the solid carrier is a sodium salt such as sodium sulfate.

[0115] In one embodiment, the solid carrier is selected from the group consisting of monosaccharides, disaccharides, and polysaccharides and their derivatives, such as sucrose, starch, cellulose, methylcellulose, ethylcellulose, propylcellulose, polyols / sugar alcohols (such as sorbitol, maltitol, xylitol, erythritol, and isomalt). Also included are PEG, PVP, citric acid or any water-soluble solid acid, fatty alcohols or fatty acids, and mixtures thereof.

[0116] In one embodiment, the solid carrier is selected from the group consisting of polyethylene glycol (PEG), polyvinylpyrrolidone (PVP), urea, water-soluble organic solid acids, water-soluble fatty alcohols or fatty acids, and mixtures thereof.

[0117] When using a solid carrier, the proportion of the solid carrier is between about 10 wt.-% and 99.9 wt.-% of the total weight of the solid composition, preferably between about 30 wt.-% and 97 wt.-% and more preferably between about 50 wt.-% and 95 wt.-%. Under these conditions, the solid composition may be kept below the critical explosion value, even when in powder form, in terms of explosiveness class and minimum ignition energy value.

[0118] As an alternative to or in addition to a solid carrier, the solid-form composition according to the present invention may also contain a fluidizer. The fluidizer may be selected from the group consisting of silicon dioxide, sodium salts, calcium salts, and zeolites. The fluidizer limits the risk of powder aggregation and clogging and facilitates the transfer of the solid composition from one container to another.

[0119] In one embodiment, the median particle size by volume (Dv(50)) in a solid composition is between approximately 10 μm and approximately 10,000 μm, arbitrarily between approximately 25 μm and approximately 1,000 μm, arbitrarily between approximately 50 μm and approximately 500 μm, and arbitrarily between approximately 50 μm and approximately 250 μm.

[0120] method A further aspect of the present invention relates to a method for producing the compositions described herein. This method includes the following steps: a) To provide a slurry of microcapsules containing an encapsulated stimulant, wherein the stimulant is encapsulated in a microcapsule comprising a core shell, which includes a core and a shell surrounding the core; b) Optionally, the slurry of microcapsules from step a) is subjected to drying, particularly spray drying, to obtain a solid composition; c) To provide emulsions or suspensions of a water-soluble polymer matrix material and optionally an unencapsulated beneficial agent; d) optionally, to obtain a solid composition by subjecting an emulsion or suspension of a water-soluble polymer matrix material and optionally an unencapsulated beneficial agent to drying, particularly by spray drying; e) Blend the composition from step a) with the composition from step c), or blend the composition from step b) with the composition from step d); f) Optionally, obtain a solid composition by drying, particularly by spray drying, the blend resulting from blending the composition of step a) with the composition of step c); Here, if steps b) and d) are performed, then step f) will not be performed; and Here, the composition contains about 54 wt% to about 85 wt%, optionally between about 55 wt% and about 75 wt%, preferably about 55 wt%, of the enriching agent based on the total dry weight of the composition.

[0121] The water-soluble matrix, meristem, and core-shell microcapsule are as defined above herein. In one embodiment, a solid support may be added between step e) if both step b) and step d) are carried out; or between step f).

[0122] The present invention also relates to consumer products comprising the compositions described herein. In one embodiment, the consumer product is selected from the group consisting of personal care products, fabric care products, home care products, or pet care products, preferably the consumer product is a fabric care product.

[0123] In one aspect, the consumer product is laundry detergent. Consumer products may contain the compositions described herein at a level of preferably 0.005 to 5 wt.-%, more preferably 0.01 to 1 wt.-%, and even more preferably 0.02 to 0.5 wt.-% of the consumer product.

[0124] The present invention also relates to the use of compositions or consumer products described herein for improving the perception or enhancing the performance of beneficial agents in consumer products. The present invention can be further illustrated by the following non-limiting examples.

[0125] Example 1: Preparation of compositions 1-4 (according to the present invention) and 5 and 6 (for comparison) by co-spraying. Measure 450g of tap water into a stainless steel beaker. Then, measure sodium starch octenyl succinate E1450 (amount according to Table 1) and mannitol 60 (amount according to Table 1) into the same beaker. Obtain a homogeneous solution by first stirring the resulting mixture manually with a stainless steel rod, and then homogenizing it at 13,500 rpm using an IKA T25 Ultra-Turrax Homogenizer. Add the fragrance (amount according to Table 1) to this resulting mixture. Create a stable emulsion using a two-stage high-pressure homogenizer. The droplet size is controlled by dynamic light scattering to be between 1 and 5 μm.

[0126] Add the core-shell microcapsule slurry (prepared according to Example 1 of WO2016 / 207180A1, in the amount specified in Table 1) to the emulsion and stir at 300 rpm for 10 minutes.

[0127] The resulting mixture is subjected to spray drying using a Mobile Niro spray dryer. The parameters for the spray drying process are as follows: - Inlet temperature: 190℃ - Outlet temperature: 90℃ - Peristaltic pump speed: 1.5 L / h - Fan speed: 80 kg / h

[0128] Table 1: Compositions 1-6 [Table 1]

[0129] Example 2: Preparation of compositions 2' and 3' (according to the present invention) by blending Add the following to the blender: a) A composition comprising a contained fragrance, sodium octenyl succinate starch (E1450), and mannitol in amounts according to Table 1, wherein the composition is in powder form; b) A composition comprising a dry microcapsule slurry in the amount specified in Table 1. Close the blender and blend the two compositions for 25-30 minutes, or until the resulting mixture is uniform.

[0130] Example 3: Comparison of olfactory performance of laundry detergents containing compositions 1-6, 2', and 3'. Olfactory performance was evaluated by a panel of four panelists, who assessed the intensity of the odor on a scale of 1 to 5 (0 = odorless, 1 = weak intensity, 2 = acceptable intensity, 3 = good intensity, 4 = strong intensity, and 5 = very strong intensity).

[0131] The following protocol was followed for the application of handwashing: Laundry: Two 100% cotton terry towels (approximately 70g, 30cm x 30cm). Volume of water: 3L Water details: Standard tap water Base: Dali powder detergent (unscented) Dosage: 0.1 wt% of spray-dried composition in a detergent sample

[0132] • Detergent dosage: 12g of detergent Measure out the amount of detergent (12g). • Pour 3 liters of room temperature water into the sink (measured by a thermometer). • Dissolve the powder by pouring it into water and stirring by hand for 30 seconds. Add two towels to the sink, one after the other. • Push each towel up and down 10 times underwater. Soak both towels for 30 minutes. • Re-lather each towel by pressing it up and down 10 times in the water. Prepare a washbasin filled with 3 liters of water. Rinse two towels in a washbasin (by pushing each towel up and down 10 times in the water). • Wring out the towel by hand. Dry the towel at room temperature for 24 hours.

[0133] After hand-washing and drying towels at room temperature (approximately 20°C) for 24 hours, an olfactory evaluation was performed before rubbing, measuring the perceived fragrance intensity before rubbing. A portion of the air-dried towel was gently rubbed, and an evaluation was performed after rubbing, measuring the intensity of the fragrance boost. Table 2 shows the performance of the freshly prepared compositions and the compositions after 2 weeks at 4°C and 37°C on terry towels.

[0134] Table 2: Olfactory performance of detergents containing compositions 1-5, 2', and 3' [Table 2] From the data above, despite prior art teaching that compositions with a fragrance load exceeding 30% lack stability, the compositions of the present invention (1-4, 2', and 3'), when used in laundry detergents, exhibit good stability over two weeks (at both low and high temperatures), at least equivalent to or better than comparative composition 6, which contains significantly less total fragrance than the compositions of the present invention. As expected, comparative composition 5 (which does not contain fragrance encapsulated in core-shell microcapsules) showed no strength after rubbing.

[0135] Furthermore, it has been observed that a composition containing a total fragrance amount between approximately 54 wt% and approximately 85 wt% based on the total dry weight of the composition, in addition to at least 31 wt% of fragrance encapsulated in core-shell microcapsules, exhibits superior olfactory performance when used in laundry detergents compared to a composition (capsule 4) in which the concentration of fragrance encapsulated in core-shell microcapsules is less than 31 wt% (compositions 1-3, 2', and 3').

[0136] Example 4: Preparation of compositions 7-10 using a high amount of fragrance Compositions 7-10 were prepared using the same method as described in Example 1, the same materials as in Example 1, and in the amounts specified in Table 3, with a total fragrance content ranging from over 54 wt% to a maximum of approximately 85 wt%.

[0137] Table 3: Compositions 7-10 [Table 3] Compositions 7-10 exhibit good stability and consistent performance over a period of approximately 12 weeks at 37°C.
