Description

[Technical Field]

[0001] The present invention relates to a detergent composition containing a capsule encapsulating a functional agent. [Background technology]

[0002] Functional agents such as fragrances, sensory agents, moisturizers, and disinfectants are incorporated into products for various purposes. For example, fragrances are used in products such as fabric softeners, laundry detergents, and body washes to add scent to the product itself, clothing, and the body. In such cases, it is necessary to be able to stably retain the fragrance so that it does not escape within the product. To prolong the effects of these functional agents, attempts are being made to encapsulate them in microcapsules and incorporate them into products. Furthermore, conventional microcapsules using resins such as melamine as wall material may be classified as microplastics due to future rule changes based on increased social environmental awareness, raising concerns about environmental impact. On the other hand, silica capsules, because their wall material is an inorganic compound, are not classified as microplastics, and if they can be incorporated into products, a reduction in environmental impact can be expected.

[0003] Patent Document 1 discloses a microcapsule having an average particle size of 0.5 μm or more and 50 μm or less, which is obtained by a predetermined manufacturing method and comprises a core made of one or more organic compounds, a first shell enclosing the core and containing silica as a constituent component, and a second shell enclosing the first shell and containing silica as a constituent component.

[0004] Patent Document 2 discloses an aqueous liquid detergent and cleaning agent containing a surfactant and other common components of detergents and cleaning agents, wherein the agent contains at least one capsule, the capsule containing an active ingredient, aluminum silicate and silica in a matrix, and the aluminum silicate and silica are present in a ratio of 1:10 to 10:1.

[0005] Patent Document 3 discloses a fragrance carrier system comprising a encapsulated fragrance composition, wherein the fragrance composition contains an emulsion of a fragrance compound in an aqueous medium and is encapsulated within a shell containing a silicon-containing material, the average diameter size of the shell being less than 30 micrometers, and a surfactant composition containing the fragrance carrier system.

[0006] [Patent Document 1] Japanese Patent Publication No. 2015-128762 [Patent Document 2] Special Publication No. 2009-504812 [Patent Document 3] Special Publication No. 2011-517323 [Overview of the project] [Problems that the invention aims to solve]

[0007] The present inventors have found that in the washing process of textile products, silica capsules containing functional agents adsorbed onto the textile product during washing detach from the textile product during rinsing, resulting in a problem where the effectiveness of the silica capsules containing the functional agent (for example, the release of fragrance from the fragrance contained in the silica capsules) cannot be obtained when the textile product is used (for example, when wearing the clothing).

[0008] In other words, the present invention provides a detergent composition, a method for producing the same, a method for washing textile products, and a kit for a washing solution that suppresses the detachment of silica capsules containing a functional agent adsorbed on the textile product from the textile product during rinsing in the washing process of textile products. [Means for solving the problem]

[0009] The present invention relates to a detergent composition containing the following components (A), (B), and water. (A) Ingredients: Silica capsules containing functional agents (B) Component: Cationic polymer (excluding those encapsulated in the silica capsule of component (A))

[0010] The present invention also relates to a method for washing textile products, comprising washing textile products using a washing solution obtained by mixing the washing agent composition of the present invention with water, and then rinsing the textile products with water.

[0011] The present invention also relates to a cleaning solution kit comprising a first agent containing component (A) and a second agent containing component (B).

[0012] The present invention also relates to a method for producing a detergent composition by mixing component (A), component (B), and water. [Effects of the Invention]

[0013] The present invention provides a detergent composition, a method for producing the same, a method for washing textile products, and a kit for a washing solution, which suppress the detachment of silica capsules containing a functional agent adsorbed on the textile product from the textile product during rinsing in the washing process of textile products. [Modes for carrying out the invention]

[0014] The reason why the detergent composition, textile product cleaning method, and cleaning solution kit of the present invention suppress the detachment of silica capsules containing the functional agent adsorbed on the textile product during rinsing in the textile product cleaning process is not entirely clear, but it is presumed to be as follows: During the textile product cleaning process, component (A), whose capsule surface is negatively charged, and component (B), which has a cationic group and is positively charged, have an electrostatic interaction, and it is expected that these two components form a complex and are adsorbed onto the fibers. Furthermore, since component (B) is a polymer, it has a certain degree of adhesiveness, and component (A), which does not have adhesiveness on its own, is given a certain degree of adhesiveness by forming a complex with component (B). Therefore, it is presumed that even when mechanical force due to the water flow is applied to the textile product during the subsequent rinsing process, the detachment of component (A) adsorbed on the textile product is suppressed.

[0015] [Detergent composition] <(A) component> The detergent composition of the present invention contains a silica capsule containing a functional agent as component (A). Examples of silica capsules containing functional agents of component (A) include those having a shell containing silica as a constituent component and a core enclosed in the shell and containing one or more functional agents.

[0016] (shell) Component (A) includes those having a shell containing silica as a constituent component. The shell of component (A) may be made up of silica as a constituent component in part or substantially all of the structure constituting the shell. From the viewpoint of suppressing the detachment of the functional agent-containing silica capsule from the textile product during rinsing, it is preferable that the silica is produced from raw material silica that generates a silanol compound by hydrolysis of alkoxysilane or the like. From the viewpoint of suppressing the detachment of the functional agent-containing silica capsule from the textile product during rinsing, it is preferable that the shell of component (A) of the present invention is formed by a sol-gel reaction using alkoxysilane as a precursor. In the present invention, "sol-gel reaction" means a reaction in which alkoxysilane undergoes hydrolysis and polycondensation reactions to form silica, which is a constituent component of the shell, via sol and gel states. Specifically, for example, tetraalkoxysilane is hydrolyzed, the silanol compound generates a siloxane oligomer through dehydration condensation and de-alcoholization condensation reactions, and silica is formed by further dehydration condensation reactions.

[0017] Examples of raw material silica include at least one selected from the group consisting of silicon tetrachloride, tetraalkoxysilane, alkylalkoxysilane, water glass, and metal silicates. From the viewpoint of suppressing the detachment of the silica capsule containing the functional agent from the textile product during rinsing, tetraalkoxysilane or alkylalkoxysilane is preferred among the raw material silica, and tetraalkoxysilane is more preferred.

[0018] Specific examples of tetraalkoxysilanes include tetramethoxysilane, tetraethoxysilane, and tetrapropoxysilane. From the viewpoint of suppressing the detachment of the silica capsule containing the functional agent from the textile product during rinsing, tetramethoxysilane and tetraethoxysilane are preferred, and tetraethoxysilane is more preferred. Specific examples of alkylalkoxysilanes include methyltrimethoxysilane, methyltriethoxysilane, ethyltrimethoxysilane, ethyltriethoxysilane, phenyltrimethoxysilane, phenyltriethoxysilane, dimethyldimethoxysilane, methylphenyldimethoxysilane, dimethyldiethoxysilane, diphenyldiethoxysilane, methylphenyldiethoxysilane, ethylphenyldimethoxysilane, diethyldiethoxysilane, ethylphenyldiethoxysilane, trimethylmethoxysilane, trimethylethoxysilane, dimethylphenylethoxysilane, triethylmethoxysilane, and triethylethoxysilane. These can be used individually or in combination of two or more types. Their condensed products can also be used.

[0019] Furthermore, the shell of the silica capsule of the present invention may contain inorganic polymers other than silica as constituent components, to the extent that they do not impair the effects of the present invention. In the present invention, an inorganic polymer refers to a polymer containing inorganic elements. Examples of such inorganic polymers include polymers consisting only of inorganic elements, and polymers in which the main chain consists only of inorganic elements and has organic groups as side chains or substituents. From the viewpoint of suppressing the detachment of the silica capsule containing the functional agent from the textile product during rinsing, the inorganic polymer is preferably a metal oxide containing a metal element or a metalloid element, and more preferably a metal alkoxide [M(OR)] x This polymer is formed using [ ] as a precursor by a reaction similar to the silica sol-gel reaction described above. Here, M is a metal or metalloid element, and R is a hydrocarbon group. Examples of metals or metalloid elements that constitute metal alkoxides include titanium, zirconium, aluminum, and zinc.

[0020] The shell may have a first shell and a second shell, and component (A) may have a first shell enclosing a core containing one or more functional agents, and a second shell enclosing the first shell. That is, component (A) may have a second shell composed of silica, a first shell enclosed in the second shell and containing silica as a component, and a core enclosed in the first shell and containing one or more functional agents. Furthermore, component (A) of the present invention may have a third shell made of an organic polymer compound that encloses the second shell. Such a multilayer shell can retain functional agents such as fragrances for a long period of time and is preferable from the viewpoint of suppressing the detachment of the silica capsules containing the functional agents from the textile product during rinsing.

[0021] The thickness of the shell (or the first shell if there is a first and second shell) is preferably 5 nm or more, preferably 20 nm or less, and more preferably 15 nm or less, from the viewpoint of suppressing the detachment of the silica capsules containing the functional agent from the textile product during rinsing. Furthermore, from the viewpoint of suppressing the detachment of the silica capsules containing the functional agent from the textile product during rinsing, the shell (first shell) is preferably a dense layer with as few pores as possible in order to retain the encapsulated functional agent for a long period of time.

[0022] (A) If component has a second shell, the thickness of the second shell is preferably 10 nm or more, more preferably 20 nm or more, and preferably 100 nm or less, and more preferably 80 nm or less, from the viewpoint of suppressing the detachment of the functional agent-encapsulating silica capsule from the textile product during rinsing. The second shell preferably has a mesoporous structure, which is a higher-order structure in which silica exists not only in the direction along the interface with the first shell but also in the thickness direction, from the viewpoint of suppressing the detachment of the functional agent-encapsulating silica capsule from the textile product during rinsing. Here, the "mesoporous structure" in the second shell refers to a structure in which the diameter of the pores (so-called mesopores) present in the structure is preferably greater than 2 nm, more preferably 10 nm or more, even more preferably 30 nm or more, and preferably 50 nm or less, more preferably 45 nm or less, and even more preferably 40 nm or less, from the viewpoint of suppressing the detachment of the silica capsule containing the functional agent from the textile product during rinsing. Due to the mesoporous structure of the second shell, component (A) possesses high mechanical strength.

[0023] The average thickness of the first and second shells of component (A), as well as the pore diameters of the first and second shells, can be measured by transmission electron microscopy (TEM). Specifically, the thickness of the first and second shells and the pore diameters of the first and second shells are measured on photographs under transmission electron microscopy. This operation is performed by changing the field of view five times. From the obtained data, the distribution of the thickness and pore diameter of the first and second shells is determined. The approximate magnification of the transmission electron microscope is 10,000 to 100,000 times, but it is adjusted appropriately depending on the size of component (A). Here, for example, the product name "JEM-2100" (manufactured by JEOL Ltd.) can be used as the transmission electron microscope (TEM).

[0024] (core) The core of component (A) of the present invention comprises one or more functional agents. The functional agent may be, for example, an oil-soluble liquid. When a fragrance is used as the functional agent, component (A) encapsulates the fragrance inside the shell, and when the shell breaks, the fragrance is released and emits a scent.

[0025] Examples of functional agents include one or more selected from fragrances, fragrance precursors, oils, antioxidants, cooling agents, warming agents, antibacterial agents, dyes, pigments, UV absorbers, silicones, solvents, and oil-soluble polymers; further, one or more selected from fragrances, fragrance precursors, oils, antioxidants, cooling agents, warming agents, antibacterial agents, UV absorbers, and solvents; and further, one or more selected from fragrances and fragrance precursors. In addition, the functional agent may be one or more selected from skincare ingredients such as moisturizers, cosmetic oils, preservatives, antioxidants, insecticides, and insect repellents.

[0026] Examples of fragrances include γ-undecalactone, 2-cyclohexylidene-2-phenylacetonitrile, damascenone, δ-damascone, α-methyl-β-(pt-butylphenyl)-propionaldehyde, β-ionone, myraldehyde, ethyltricyclo[5.2.1.0-2,6]decane-2-carboxylate, citronellol, geraniol, α-ionone, patchouli alcohol, 6,7-dihydro-1,1,2,3,3-pentamethyl-4(5H)-indanone, methyl Dihydrojasmonate, hexyl cinnamic aldehyde, amyl cinnamic aldehyde, allylcyclohexyl propionate, dimethylbenzylcarbin butyrate, tricyclodecenyl propionate, amyl salicylate, γ-methyl ionone, α-damascone, β-damascone, nerolin jalayala, phenylhexanol, 2-methyl-4-(2,2,3-trimethyl-3-cyclopenten-1-yl)-2-buten-1-ol, dodecahydro-3a,6,6,9a-tetramethyl Naphtho[2,1-b]furan, γ-nonalactone, methyl β-naphthylketone, eugenol, lyral, dimethylbenzylcarbyl acetate, isodamascone, 2-cyclohexylidene-2-phenylacetonitrile, γ-decalactone, α-methyl-3,4-methylenedioxyhydrocinnamicaldehyde, 7-methyl-3,5-dihydro-2H-benzodioxepinone, tricyclodecinyl acetate (tricyclodecenyl acetate), tricyclodecinyl propionate, 2-pentene Allyl hydroxyglycolate, 1-(2-tert-butylcyclohexyloxy)-2-butanol, citronelloxyacetaldehyde, indole, 4-methyl-3-decen-5-ol, para-menthan-8-thiol-3-one, 3-(para-tert-butylphenyl)-propanal, ethyl cinnamate, 5-methyl-3-heptanone oxime, methyl anthranilate, terpineol, β-caryophyllene, citronellyl acetate, geranyl acetate, neryl acetate, p,t-butylcyclohexyl acetate, o,t-butylcyclohexyl acetate, tetrahydrogeraniol, 2-isobutyl-4-hydroxy-4-methyltetrahydropyranol (florosa), α-dynascone, cisjasmon, bicyclo[3.2.1) Octane-8-one-1,5-dimethyl-oxime, 2,4-dimethyl-4,4α,5,9β-tetrahydroindeno[1,2-d]-m-dioxin, 3-(para-ethylphenyl)-2,2-dimethylpropanal, ethyl-2-tert-butylcyclohexyl carbonate, hexyl benzoate, 4-acetoxy-3-amyltetrahydropyran, dodecylaldehyde, dihydro-β-ionone, methylcyclooctyl carbonate, methylf Ethyl phenylglycidate, isoeugenol, diphenyl oxide, 2,2,5-trimethyl-5-pentylcyclopentanone, thymol, nerolin bromeliad, 5,6-dimethyl-8-isopropenyl, bicyclo"4,4,0"-1-decen-3-one, 3-(4-isopropylphenyl)-propanal, 4-isopropylcyclohexanemethanol, methyl methyl anthranilate, dodecanenitrile 3-dodecenal, octanal, nonanal, de Canal, Lilial, p,t-butylhydrocinnamic aldehyde, dimethyltetrahydrobenzaldehyde, hexyl acetate, linalyl acetate, terpinyl acetate, allyl caproate, hexyl salicylate, benzyl salicylate, cyclohexyl salicylate, cis-3-hexenyl salicylate, methyl dihydrojasmonate, cyclamenaldehyde, limonene, linalool, tetrahydrolinalool, dihydromyrcenol, methyl β-naphthyl ketone, i Examples include So-E Super, cedyl methyl ether, Javanol (manufactured by Divaudan), ambroxan, 1,8-cineole, geranyl nitrile, citronellyl nitrile, 11-oxa-16-hexadecanolide (Musk R-1, manufactured by Divaudan), ethylene brassirate, ethylenedodecanediate, cashmeran, cyclopentadecanolide, cyclohexadecanolide, and ambrettelide. The fragrance may be a fragrance composition containing several of these fragrances.

[0027] Examples of fragrance precursors include compounds that release fragrance components upon reaction with water. Specifically, these include silicate ester compounds having an alkoxy component derived from fragrance alcohol, fatty acid ester compounds having an alkoxy component derived from fragrance alcohol, acetal compounds or hemiacetal compounds obtained by the reaction of a carbonyl component derived from a fragrance aldehyde or fragrance ketone with an alcohol compound, Schiff base compounds obtained by the reaction of a carbonyl component derived from a fragrance aldehyde or fragrance ketone with a primary amine compound, and hemiaminal compounds or hydrazone compounds obtained by the reaction of a carbonyl component derived from a fragrance aldehyde or fragrance ketone with a hydrazine compound.

[0028] Other forms of fragrance precursors include compounds that release fragrance components in response to light. Examples include 2-nitrobenzyl ether compounds having an alkoxy component derived from fragrance alcohol, α-ketoester compounds having a carbonyl component derived from fragrance aldehyde or fragrance ketone, and coumaric acid ester compounds having an alkoxy component derived from fragrance alcohol. These fragrance precursors may also be used as polymers, for example, as reaction products between some carboxyl groups of polyacrylic acid and fragrance alcohol. Among these, silicate ester compounds having an alkoxy component derived from fragrance alcohol are preferred. One or more of these fragrance precursors can be used.

[0029] The ClogP value of the functional agent is preferably 2 or higher, more preferably 3 or higher, even more preferably 4 or higher, and preferably 30 or lower, more preferably 20 or lower, and even more preferably 10 or lower. A ClogP value of 2 or higher for the functional agent improves the encapsulation rate (hereinafter also referred to as "encapsulation rate") of the functional agent within component (A). The same applies when the functional agent is a fragrance composition containing multiple fragrances; a ClogP value of 2 or higher for the fragrance composition improves the encapsulation rate (encapsulation rate) of the fragrance composition within component (A). Here, the ClogP value is the "calculated logP(ClogP)" calculated using the method described in A. Leo in "Comprehensive Medicinal Chemistry", Vol. 4, (C. Hansch, PG Sammes, JB Taylor and CARamsden, Eds.), p. 295, Pergamon Press, 1990, and is the ClogP value calculated using the program CLOGP v4.01. In the case of a fragrance composition containing multiple fragrances, the CLogP value of the fragrance composition can be obtained by multiplying the CLogP value of each fragrance by its volume ratio in the fragrance composition and summing them up.

[0030] Furthermore, from the viewpoint of retaining the functional agent, the oil-water interface tension of the functional agent is preferably 7 mN / m or more, more preferably 10 mN / m or more, and even more preferably 13 mN / m or more at 25°C. The oil-water interface tension of the functional agent can be measured, for example, using a contact angle meter "DropMaster DM-501" (product name, manufactured by Kyowa Interface Science Co., Ltd.).

[0031] (A) The volume-average particle size of component (A) is preferably 0.5 μm or more, more preferably 0.7 μm or more, even more preferably 1 μm or more, and preferably 50 μm or less, more preferably 10 μm or less, and even more preferably 5 μm or less, from the viewpoint of compatibility with the product and retention of the functional agent. In this invention, the volume-average particle size of component (A) can be measured by the method described in the examples. For example, it can be measured using the laser diffraction / scattering particle size distribution analyzer "LA-960" (product name, manufactured by Horiba, Ltd.). In this case, a flow cell is used for measurement, the medium is water, and the refractive index is set to 1.40-0i. A dispersion containing component (A) is added to the flow cell, and the measurement is performed at a concentration where the transmittance is around 90%, and the average particle size is determined on a volume basis.

[0032] If component (A) has a second shell containing silica as a constituent component, a first shell enclosed within the second shell and containing silica as a constituent component, and a core enclosed within the first shell and containing one or more functional agents, then component (A) can be obtained, for example, by a manufacturing method having the following steps (1) and (2). Step (1): A step in which an organic phase containing one or more functional agents and raw material silica (e.g., tetraalkoxysilane) is mixed with an aqueous phase containing a surfactant (e.g., a cationic surfactant) and emulsified, and then a sol-gel reaction is carried out under acidic conditions to form a shell and create a capsule containing the functional agent. Step (2): A step in which raw material silica (e.g., tetraalkoxysilane) is added to the dispersion containing the capsules obtained in step (1) to carry out a sol-gel reaction and form a capsule having a second shell that encloses the first shell. More specifically, component (A) can be obtained, for example, by a manufacturing method comprising the following steps (1a) and (2a), and optionally further comprising the following step (3a). Step (1a): A step in which an organic phase containing one or more functional agents and tetraalkoxysilane, wherein the amount of tetraalkoxysilane is 10% by mass or more and 60% by mass or less relative to the functional agent is emulsified in an aqueous phase containing a surfactant (e.g., a cationic surfactant), a sol-gel reaction is carried out under acidic conditions to form a capsule having a core and a first shell. Step (2a): A step in which a tetraalkoxysilane is added to an aqueous dispersion containing the capsule obtained in step (1a), and the initial pH of the sol-gel reaction in step (2a) is maintained lower than the initial pH of the sol-gel reaction in step (1a), and the sol-gel reaction is carried out to form a capsule having a second shell enclosing a first shell. Step (3a): A step of mixing a dispersion containing the capsules obtained in step (2a) with an aqueous solution containing an organic polymer compound (e.g., an anionic synthetic polymer compound) to form capsules having a third shell.

[0033] Here, the "sol-gel reaction" in steps (1) and (2), as well as steps (1a) and (2a), is a reaction in which raw material silica (silica precursor) is polymerized while removing alcohol by hydrolysis and polycondensation under acidic conditions to synthesize the first and second shells of silica.

[0034] The above manufacturing method can be carried out by referring to, for example, Japanese Patent Publication No. 2015-128762 and Japanese Patent Publication No. 2017-114802. In the above manufacturing method, component (A) is usually obtained in a dispersed state in water. Depending on the application, this aqueous dispersion can be used as is, but in some cases, component (A) is separated before use. As a separation method, filtration, centrifugation, etc. can be used.

[0035] (A) The proportion of the functional agent in the components may be, for example, 5% by mass or more, further 10% by mass or more, further 12% by mass or more, and 50% by mass or less, further 45% by mass or less, and further 40% by mass or less.

[0036] <(B) component> The detergent composition of the present invention contains a cationic polymer as component (B). However, the cationic polymer encapsulated in component (A) is excluded from component (B).

[0037] The weight-average molecular weight of component (B) of the present invention is preferably 100,000 or more, more preferably 500,000 or more, even more preferably 1,000,000 or more, even more preferably 1,500,000 or more, and preferably 5,000,000 or less, more preferably 4,000,000 or less, even more preferably 3,000,000 or less, even more preferably 2,500,000 or less, and even more preferably 2,000,000 or less, from the viewpoint of suppressing the detachment of the silica capsule containing the functional agent from the textile product during rinsing.

[0038] (B) Component is preferably one or more selected from (B1) a polysaccharide derivative having a cationic group (hereinafter referred to as (B1) component) and (B2) a cationic polymer obtained by polymerizing an unsaturated monomer having a cationic group (hereinafter referred to as (B2) component), from the viewpoint of suppressing the detachment of the silica capsule containing the functional agent from the textile product during rinsing, and (B2) a cationic polymer obtained by polymerizing an unsaturated monomer having a cationic group is more preferred.

[0039] Component (B1) is a polysaccharide derivative having a cationic group. The (B1) component of the present invention is characterized by being a polysaccharide derivative in which a cationic group is directly or via a linking group bonded to a hydroxyl group from which a hydrogen atom has been removed, which is a precursor compound of component (B1) or a derivative thereof. The phrase "a cationic group is directly or via a linking group bonded to a hydroxyl group from which a hydrogen atom has been removed, which is a polysaccharide or a derivative thereof" does not include bonding modes in which the cationic atom of the cationic group, such as a nitrogen cation, is directly covalently bonded to the hydroxyl group from which a hydrogen atom has been removed, i.e., the oxygen atom.

[0040] As for the polysaccharide, from the viewpoint of suppressing the detachment of the silica capsule containing the functional agent from the textile product during rinsing, for example, one or more polysaccharides selected from cellulose, guar gum, and starch can be used. Component (B1) is a polysaccharide derivative, but a polysaccharide derivative can be used as a precursor compound to obtain it. That is, component (B1) may be a derivative of a polysaccharide derivative. Examples of polysaccharide derivatives that are precursor compounds of component (B1) include polysaccharide derivatives in which some or all of the hydrogen atoms of the hydroxyl group of the polysaccharide are substituted with a hydroxyalkyl group having 1 to 4 carbon atoms (hereinafter also referred to as a hydroxyalkyl substituted product). From the viewpoint of suppressing the detachment of the silica capsule containing the functional agent from the textile product during rinsing, the hydroxyalkyl group having 1 to 4 carbon atoms is preferably a hydroxyalkyl group having 2 to 4 carbon atoms. Examples of hydroxyalkyl groups having 2 to 4 carbon atoms include one or more groups selected from hydroxyethyl, hydroxypropyl, and hydroxybutyl groups, and from the viewpoint of suppressing the detachment of the silica capsule containing the functional agent from the textile product during rinsing, one or more groups selected from hydroxyethyl and hydroxypropyl groups are preferred. Component (B1) may be a polysaccharide derivative in which a cationic group has been introduced into one or more polysaccharides selected from cellulose, guar gum, and starch, or a polysaccharide derivative selected from hydroxyalkyl substituted products thereof.

[0041] Polysaccharide derivatives having a cationic group of component (B1) include polysaccharides that are precursor compounds of component (B1), or derivatives thereof, preferably the hydroxyalkyl substituted product, to which a cationic group is bonded via a linking group, which is an alkylene group having 1 to 4 carbon atoms and may contain a hydroxyl group [hereinafter referred to as linking group (1)]. From the viewpoint of suppressing the detachment of the silica capsule containing the functional agent from the textile product during rinsing, the cationic group is preferably a group containing a nitrogen cation, and more preferably a quaternary ammonium group.

[0042] The linking group (1) is an alkylene group having 1 to 4 carbon atoms, which may contain a hydroxyl group. Examples of alkylene groups having 1 to 4 carbon atoms include one or more alkylene groups selected from linear alkylene groups having 1 to 4 carbon atoms, which may contain a hydroxyl group, and branched alkylene groups having 1 to 4 carbon atoms, which may contain a hydroxyl group.

[0043] When the cationic group is a quaternary ammonium group, the three hydrocarbon groups other than the linking group (1) bonded to the quaternary ammonium group can each be independently a linear or branched hydrocarbon group having 1 to 4 carbon atoms. Examples of linear hydrocarbon groups having 1 to 4 carbon atoms include groups selected from methyl, ethyl, n-propyl, and n-butyl groups. Examples of branched hydrocarbon groups having 1 to 4 carbon atoms include groups selected from isopropyl, sec-butyl, tert-butyl, and isobutyl groups. From the viewpoint of suppressing the detachment of the silica capsule containing the functional agent from the textile product during rinsing, a methyl or ethyl group is preferred as the linear hydrocarbon group having 1 to 4 carbon atoms. The counterion for the quaternary ammonium group can be one or more counterions selected from alkyl sulfate ions having 1 to 3 carbon atoms, sulfate ions, phosphate ions, fatty acid ions having 1 to 3 carbon atoms, and halide ions. Among these, from the viewpoint of ease of manufacture, availability of raw materials, and suppression of detachment of the silica capsule containing the functional agent from the textile product during rinsing, it is preferable to use one or more selected from alkyl sulfate ions having 1 to 3 carbon atoms, sulfate ions, and halide ions, more preferably halide ions. Examples of halide ions include one or more selected from fluoride ions, chloride ions, bromide ions, and iodide ions. From the viewpoint of water solubility and chemical stability of the polysaccharide derivative of component (B1) and suppression of detachment of the silica capsule containing the functional agent from the textile product during rinsing, it is preferable to use one or more selected from chloride ions and bromide ions, more preferably chloride ions. Note that the counterion may be a single type or two or more types.

[0044] The degree of substitution (cationization) of the cationic group of the polysaccharide derivative having a cationic group in component (B1) is preferably 0.001 or higher, more preferably 0.01 or higher, even more preferably 0.1 or higher, even more preferably 0.5 or higher, and preferably 1.5 or lower, more preferably 1.4 or lower, and even more preferably 1.3 or lower, from the viewpoint of suppressing the detachment of the silica capsule containing the functional agent from the textile product during rinsing.

[0045] Component (B1) may have a hydrocarbon group having 1 to 18 carbon atoms. That is, component (B1) may be a polysaccharide derivative having both a cationic group and a hydrocarbon group having 1 to 18 carbon atoms. Among the components of (B1), polysaccharide derivatives having hydrocarbon groups with 1 to 18 carbon atoms include polysaccharide derivatives in which hydrocarbon groups with 1 to 18 carbon atoms are bonded directly or via a linking group (hereinafter referred to as linking group (2)) to a polysaccharide or derivative thereof that is a precursor compound of component (B1).

[0046] The aforementioned linking group (2) can be one or more groups selected from an alkylene oxy group having 1 to 3 carbon atoms which may have a hydroxyl group, a polyoxyalkylene group in which the alkylene group has 1 to 3 carbon atoms, a carbonyl group, a carbonyl oxy group, and an oxycarbonyl group. One linking group (2) may be one of the aforementioned linking groups or may be a combination of multiple types. Furthermore, the polysaccharide derivative may contain one type of linking group or multiple types. In the present invention, when the hydrocarbon group is linked to the oxygen atom of the linking group (2), the number of carbon atoms in the hydrocarbon group of component (B1) represents the number of carbon atoms in the hydrocarbon group bonded to the oxygen atom. When the hydrocarbon group is linked via a carbonyl group, it becomes a structure with an acyl group bonded, and in this case, the number of carbon atoms in the hydrocarbon group of component (B1) represents the number of carbon atoms in the acyl group. Similarly, when linked via a carbonyloxy group and an oxycarbonyl group, the number of carbon atoms in those groups is also included. When introducing a hydrocarbon group into a polysaccharide or polysaccharide derivative using 1,2-epoxyalkane, it represents the number of carbon atoms in the aliphatic hydrocarbon group bonded to the ether group generated from the epoxy group. The epoxy group portion becomes linking group (2). For example, when introducing a hydrocarbon group into a polysaccharide or polysaccharide derivative using 1,2-epoxytetradecane, the number of carbon atoms in the hydrocarbon group is 12. In other words, an oxyethylene group, which is a linking group (2), is bonded to the hydroxyl group of a polysaccharide or polysaccharide derivative, and a C12 alkyl group (dodecyl group) is bonded via this linking group. The same applies when alkylglycidyl ethers are used.

[0047] Among the components of (B1), polysaccharide derivatives having a cationic group and a hydrocarbon group having 1 to 18 carbon atoms include polysaccharide derivatives in which a hydrocarbon group having 1 to 18 carbon atoms is bonded directly or via a linking group (2) to an oxygen atom obtained by removing a hydrogen atom from some or all of the hydroxyl groups of the hydroxyalkyl substituted product, preferably via a linking group (2) from the viewpoint of suppressing the detachment of the silica capsule containing the functional agent from the textile product during rinsing.

[0050] In the present invention, the degree of substitution of hydrocarbon groups and cationic groups having 1 to 18 carbon atoms in component (B1) refers to the number of substitutions of the group per constituent monosaccharide unit, i.e., the molar average degree of substitution (MS). For example, when the polysaccharide is cellulose, the "degree of substitution of the group" refers to the average number of moles of the group introduced per mole of anhydroglucose units. The degree of substitution of cationic groups and the degree of substitution of hydrocarbon groups having 1 to 18 carbon atoms in the polysaccharide derivative can be determined by the method described in the examples.

[0051] Component (B1) may have anionic groups, but the ratio of the degree of substitution of anionic groups in component (B1) to the sum of the degree of substitution of cationic groups and hydrocarbon groups having 1 to 18 carbon atoms is, from the viewpoint of suppressing the detachment of the silica capsule containing the functional agent from the textile product during rinsing, preferably 3 or less, more preferably 1.7 or less, even more preferably 1.5 or less, even more preferably 1 or less, even more preferably 0.5 or less, even more preferably 0.1 or less, and may be 0 or more, but is preferably 0.

[0223] <Composition ingredients> The following components were used in the examples and comparative examples. <(A) component> a-1: Silica capsules containing fragrance manufactured by the following method (1)

[0224] (Manufacturing of a-1) Process (1) 3.0 g of Cotamin 60W (product name, manufactured by Kao Corporation, cetyltrimethylammonium chloride, 30% by mass of active ingredient) was diluted with 750 g of deionized water to obtain the aqueous phase component. To this aqueous phase component, an oil phase component prepared by mixing 200 g of model fragrance A in the proportions shown in Table 1 and 50 g of tetraethoxysilane (hereinafter also referred to as "TEOS") was added, and the mixture was emulsified at a rotation speed of 8,500 rpm using a homomixer (manufactured by HsiangTai, model: HM-310, the same applies hereafter) to obtain the emulsion. The volume-average particle size of the emulsion droplets at this time was 1.4 μm. The pH of the resulting emulsion was adjusted to 3.8 using a 1% aqueous sulfuric acid solution. The mixture was then transferred to a separable flask equipped with a stirring blade and a condenser, and stirred at 200 rpm for 24 hours while maintaining the liquid temperature at 30°C to obtain an aqueous dispersion containing silica capsules having a core made of model fragrance A and a first shell made of silica.

[0225] Process (2) In step (1), 21 g of TEOS was added dropwise over 420 minutes while stirring the aqueous dispersion at a liquid temperature of 30°C. After addition, stirring was continued for a further 17 hours, followed by cooling to form a second shell enclosing the first shell, resulting in an aqueous dispersion containing silica capsules in which model fragrance A was encapsulated in amorphous silica (the content of model fragrance A (functional agent) was 19.4% by mass in the silica capsules). The volume-average particle size of the silica capsules was 2.1 μm. The volume-average particle size of the emulsion droplets and silica capsules was measured using a laser diffraction / scattering particle size distribution analyzer "LA-960" (product name, manufactured by Horiba, Ltd.). A flow cell was used for the measurement, the medium was water, and the refractive index was set to 1.40-0i. The aqueous dispersion containing the emulsion or silica capsules was added to the flow cell, and measurements were performed at a concentration where the transmittance was around 90%, and the volume-average particle size was determined on a volume basis. The thickness of the first shell was approximately 5 nm, and the thickness of the second shell was 5-30 nm.

[0226] Model fragrance A As the organic compound encapsulated in the silica capsule, model fragrance A (volume-average ClogP: 3.9, specific gravity: 0.96) having the composition shown in Table 1 was used. The volume-average ClogP value of the model fragrance was calculated by multiplying the ClogP value of each fragrance component contained in the model fragrance by the volume fraction of each component in the model fragrance, and summing these values. In this calculation, all fragrance components whose content in model fragrance A is 0.5% by mass or more were considered, and fragrance components whose content in model fragrance A is less than 0.5% by mass were also included in the calculation if their specific gravity and ClogP value were known.

[0230] The degree of substitution and weight-average molecular weight of component (B1) were measured by the following method. (1) Measurement of the degree of substitution • Pretreatment of polysaccharide derivatives (B1) One g of the polysaccharide derivative was dissolved in 100 g of water, and the aqueous solution was placed in a dialysis membrane (Spectrapore, molecular weight cutoff 1000) and dialysis was performed for two days. The resulting aqueous solution was freeze-dried using a freeze-dryer (eyela, FDU1100) to obtain the pre-treated polysaccharide derivative.

[0231] • Calculation of cation substrate amount using the Kjeldahl method 200 mg of the polysaccharide derivative pretreated by the method described above was accurately weighed, and 10 mL of concentrated sulfuric acid and 1 Kjeldahl tablet (Merck) were added. The mixture was then thermally decomposed using a Kjeldahl decomposition apparatus (BUCHI, K-432). After decomposition, 30 mL of deionized water was added to the sample, and the nitrogen content (mass%) of the sample was determined using an automated Kjeldahl distillation apparatus (BUCHI, K-370), thereby calculating the mass of the cation group.

Calibration samples were also prepared by adding 2.4 mg or 9 mg of 1-iodododecane instead of the polysaccharide derivative. Each sample was heated at 160°C for 2 hours using a block heater (PIERCE, Reacti-Therm III Heating / Stirring module) while stirring with a stirrer tip. After the samples cooled, the upper layer (o-xylene layer) was collected and analyzed by gas chromatography (GC) (Shimadzu Corporation, QD2010plus) under the following conditions. ·GC analysis conditions Column: Agilent HP-1 (Length: 30m, Liquid phase film thickness: 0.25μL, Inner diameter: 32mm) Split ratio: 20 Column temperature: 100°C (2 min) → 10°C / min → 300°C (15 min) Injector temperature: 300℃ Detector: HID Detector temperature: 330℃ Injection volume: 2 μL The mass of alkyl groups in the sample was determined from the amount of 1-iodododecane detected by GC.

[0241] <Preparation of textile products for evaluating desorption inhibition rate> 1.7 kg of cotton cloth (Cotton 2003 (manufactured by Tanigashira Shoten)) was washed twice cumulatively using the standard course of a fully automatic washing machine (National NA-F702P) (4.7 g of Emulgen 108 (manufactured by Kao Corporation) during washing, 47 L of water, 9 minutes of washing, 2 rinses, and 3 minutes of spinning). Then, it was washed three more times cumulatively with water only (47 L of water, 9 minutes of washing, 2 rinses, and 3 minutes of spinning), and dried for 24 hours in an environment of 23°C and 45% RH. After that, it was cut into 6 cm x 6 cm pieces to prepare textile products for evaluation.

Then, 30 g of the prepared evaluation textile products were added, and the evaluation textile products were washed at 85 rpm for 10 minutes while maintaining the water temperature at 20°C. After washing, the treated textile products were dehydrated for 1 minute in a Hitachi twin-tub washing machine (model number "PS-H35L"). After dehydration, five evaluation textile products were sampled (hereinafter referred to as post-wash samples), and the remaining products were placed in a stainless steel beaker with 0.6 L of water again and rinsed at 85 rpm for 10 minutes while maintaining the water temperature at 20°C. After rinsing, the treated textile products were dehydrated again in the twin-tub washing machine for 2 minutes. After dehydration, five evaluation textile products were sampled (hereinafter referred to as post-rinse samples).

[0243] <Extraction Process> Five post-wash samples or five post-rinse samples sampled in the aforementioned washing process were placed in No. 8 screw tubes (Maruemu), and 100 mL of acetone (reagent grade, Fujifilm Wako Pure Chemical Industries) containing 10 μg / mL of benzyl benzoate as an internal standard was added. This screw tube was subjected to an extraction process using an ultrasonic cleaner (BRANSON 2800, using an ice bath) for 1 hour, followed by an extraction process using a shaker (Yamato Shaker SA-300, speed: Max) for 15 minutes, and then another extraction process using the aforementioned ultrasonic cleaner (under the same conditions) for 1 hour to extract the fragrance components remaining on the fabric into the acetone.

[0244] <Quantitative determination of residual fragrance in textile products> The amount of fragrance contained in the aforementioned acetone extract was quantified by gas chromatography using the following measuring instruments and conditions. The adsorption rate of the fragrance remaining on the textile product in the post-wash or post-rinse sample was then calculated from the total amount of fragrance contained in the acetone extract. [Measuring Instruments] GC device: "Agilent Technologies7890B" (manufactured by Agilent) MS system: "Agilent Technologies 5977A" (manufactured by Agilent) Column: DB-WAX (Length: 30m, Inner diameter: 0.25mm, Film thickness: 0.25μm, Manufactured by Agilent) Inlet temperature: 240℃ Injection method: Splitless Injection volume: 1μl Temperature: 40℃ → Increase temperature at 12.5℃ / min → 240℃ (14 min) Carrier gas: Helium.

[0245] <Calculation of detachment inhibition rate> The desorption inhibition rate of silica capsules containing fragrance during rinsing was calculated using the following formula based on the adsorption rate of fragrances remaining on textile products in post-wash or post-rinse samples. The results are shown in Tables 2 and 3. A higher desorption inhibition rate indicates superior ability to inhibit the desorption of silica capsules containing functional agents from textile products during rinsing. Desorption inhibition rate (%) = (Adsorption rate of fragrance in the sample after rinsing) / (Adsorption rate of fragrance in the sample after washing) × 100
