Description

[Technical Field]

[0001] This invention relates to a textile product treatment agent composition. [Background technology]

[0002] Consumer interest in fragrances during washing, drying, and wearing clothes is increasing, and the market for liquid fabric softeners and fragrance enhancers that emphasize fragrance has grown significantly. However, because textile treatment compositions used in general households are applied to textile products via water, the fragrance may not adhere sufficiently to the fibers, or it may evaporate from the fabric during drying or over time after drying, resulting in a weakened scent. To address these problems, for example, Patent Document 1 discloses a fabric softening composition containing a specific long-lasting fragrance composition that improves the lifespan of fragrances on fabrics.

[0003] Patent Document 2 discloses a sustained-release fragrance composition that can be used in clothing, for the purpose of prolonging the fragrance, by using a mixture of dibasic acid monoesters and / or dibasic acid diesters with ethylene glycol or propylene glycol. Patent Document 3 also discloses that a fragrance can be prolonged by using an aqueous liquid containing emulsion particles obtained by emulsifying and dispersing a mixture of oils and fats with a melting point of 30°C or higher at atmospheric pressure and a fragrance composition in water.

[0004] On the other hand, as a conventional technology to improve the lingering scent during wear, attempts have been made to incorporate fragrances by microencapsulating them. Patent document 4 describes an encapsulated fragrance containing a fragrance composition with a flash point in the range of 50 to 130°C as the core material. Patent document 5 describes that the lingering scent can be improved by using microcapsules containing fragrances manufactured by the core-shell method. Patent document 6 describes that by using microcapsules containing fragrances in combination with a polymer containing a specific amine, fragrances can be uniformly attached to multiple different surfaces at high concentrations.

[0005] Furthermore, Patent Document 7 discloses a liquid fabric softener composition that, in addition to normal fragrance persistence, aims to achieve excellent odor release when the wearer perspires, comprising: (A) component containing one or more selected from specific tertiary amine compounds and their salts and quaternary compounds; (B) component consisting of microcapsules containing a fragrance encapsulating 90% by mass or more of a fragrance compound having a logP value of 2.0 to 6.0; (C) component consisting of a fragrance precursor which is an ester of a specific fragrance and a specific fatty acid ester or fatty acid diester; and water, with a pH of 2.5 to 4.0 at 30°C. Furthermore, Patent Document 8 discloses a textile product treatment agent composition containing a silicic acid ester compound and a specific fragrance, which improves the lifespan of the fragrance on the fabric. Patent Document 9 discloses a fragrance composition for fabric softener containing a silicic acid ester compound and a specific highly persistent fragrance. The silicic acid ester compound has the property of releasing fragrance when its ester bond is hydrolyzed by moisture absorption. [Prior art documents] [Patent Documents]

[0007] In recent years, several technologies have been proposed to provide lasting fragrance to textile products. However, the adsorption of fragrances added to textile treatment agents to textile products is difficult, and the scent remains on the surface of the textile product, causing it to quickly diffuse into the air. Depending on the base material, the scent may even disappear during drying. Microencapsulation of fragrances has been proposed as a means to improve the effectiveness of the fragrance, but there are still challenges in terms of fragrance release in situations involving moisture, such as during perspiration, where the release of fragrance from textile products is extremely important. Furthermore, the creation of fragrance precursors has been proposed as a means to improve effectiveness in situations involving moisture, but there are limitations in the types of fragrances that can be used, which limits the ability to satisfy a wider range of preferences. [Means for solving the problem]

[0008] The inventors of this invention conducted research to improve the effectiveness of fragrance in situations involving moisture, and discovered that by combining capsules containing silica, which has the property of disintegrating when dry, with a silicate ester compound, a good fragrance is released even in textile products that have been dried for a long period of time after treatment and are re-moistened with water or sweat.

[0009] The present invention relates to a textile product treatment agent composition containing component (a), component (b), and component (c). (a) A microcapsule having a shell containing silica and a core containing a fragrance compound inside the shell. (b) A fragrance precursor comprising an ester of an alcohol-based or phenol-based fragrance with silicic acid. (c) A component containing one or more of the components (c1) and (c2) listed below. (c1) Components: A tertiary amine compound represented by the following general formula (1), and its salt. (c2) Components: Quaternary compounds of tertiary amine compounds represented by the following general formula (1). [R 1c -C(=O)-O-(Cp H 2p O) r -C q H 2q 〕 m N(R 2c ) 3-m (C1) 〔In the formula, R 1c is a hydrocarbon group having 11 to 23 carbon atoms, and R 2c is a hydrocarbon group having 1 to 3 carbon atoms and HO-(C p H 2p O) r -C q H 2q group, m is an integer of 1 to 3, p and q are numbers of 2 or 3, and r is an integer of 0 to 5. When there are a plurality of R 1c , R 2c , p, q, and r in the same molecule, they may be the same or different.〕

[0026] The initial pH of the sol-gel reaction in step 1 is preferably 3.0 or higher, more preferably 3.3 or higher, and even more preferably 3.5 or higher, from the viewpoint of maintaining a balance between the hydrolysis and condensation reactions of the tetraalkoxysilane, and from the viewpoint of suppressing the formation of a highly hydrophilic sol and promoting the progress of encapsulation. Furthermore, from the viewpoint of suppressing the simultaneous occurrence of silica shell formation and emulsion droplet aggregation and obtaining silica capsules with a dense shell, the initial pH is preferably 4.5 or lower, more preferably 4.3 or lower, and even more preferably 4.1 or lower.

[0027] Depending on the acidity or alkalinity of the oil phase components containing the fragrance composition, any acidic or alkaline pH adjuster may be used to adjust to the desired initial pH. The pH of the emulsified solution may fall below the desired value. In such cases, it is preferable to adjust the pH using an alkaline pH adjusting agent, as described later. In other words, steps 1-4 may preferably be the following steps 1-4'. Step 1-4': The pH of the emulsion obtained in Step 1-3 is adjusted using a pH adjusting agent, and the first sol-gel reaction is carried out to form a silica capsule (1) having a core and a first shell, and an aqueous dispersion containing the silica capsule (1) is obtained.

[0028] Examples of acidic pH adjusters include solutions obtained by adding inorganic acids such as hydrochloric acid, nitric acid, and sulfuric acid, organic acids such as acetic acid and citric acid, and cation exchange resins to water or ethanol, with hydrochloric acid, sulfuric acid, nitric acid, and citric acid being preferred. Examples of alkaline pH adjusters include sodium hydroxide, sodium bicarbonate, potassium hydroxide, ammonium hydroxide, diethanolamine, triethanolamine, and trishydroxymethylaminomethane, with sodium hydroxide and ammonium hydroxide being preferred.

[0029] The reaction temperature for the sol-gel reaction in step 1 can be any value as long as it is above the melting point and below the boiling point of the water contained in the aqueous phase. However, from the viewpoint of controlling the balance between the hydrolysis reaction and the condensation reaction in the sol-gel reaction and forming a dense shell, it is preferable to keep the temperature within a certain range. This range is preferably 5°C or higher, more preferably 10°C or higher, even more preferably 15°C or higher, and preferably 60°C or lower, more preferably 50°C or lower, and even more preferably 40°C or lower.

[0032] In step 2, the tetraalkoxysilane to be added to the aqueous dispersion containing the silica capsule (1) obtained in step 1 may be added all at once, added intermittently in divided portions, or added continuously. However, from the viewpoint of forming a highly dense second shell, it is preferable to add it continuously by drop. When tetraalkoxysilane is added dropwise continuously, the dropwise addition time can be set appropriately according to the scale of production, but from the viewpoint of suppressing the separation of the added tetraalkoxysilane and the aqueous dispersion, it is preferably 5 minutes or more, more preferably 10 minutes or more, even more preferably 30 minutes or more, and preferably 1200 minutes or less, more preferably 1000 minutes or less, and even more preferably 500 minutes or less.

[0033] In the present invention, the total amount of tetraalkoxysilane added, that is, the total amount of tetraalkoxysilane used in steps 1 and 2, is preferably 30% by mass or more, more preferably 35% by mass or more, even more preferably 40% by mass or more, and preferably 250% by mass or less, more preferably 200% by mass or less, and even more preferably 150% by mass or less, relative to the fragrance compound in step 1. By keeping the total amount of tetraalkoxysilane added within the above range, the encapsulated fragrance compound can be retained for a long period of time.

[0034] In the present invention, the total amount of the fragrance compound and tetraalkoxysilane in step 1 relative to the total amount of the aqueous dispersion before the addition of tetraalkoxysilane in step 2 is preferably 20% by mass or less, more preferably 18% by mass or less, even more preferably 15% by mass or less, and even more preferably 10% by mass or less, from the viewpoint of improving the long-term retention of the fragrance compound, and from the viewpoint of production efficiency, it is preferably 2% by mass or more, more preferably 3% by mass or more, and even more preferably 5% by mass or more. The adjustment of the total amount of the fragrance compound and tetraalkoxysilane in Step 1 relative to the total amount of the aqueous dispersion before the addition of tetraalkoxysilane in Step 2 may be performed by carrying out Step 1 so that the amounts of the fragrance compound and tetraalkoxysilane in Step 1 and the total amount of the aqueous dispersion obtained in Step 1 are within the above range, or by further adding water to the aqueous dispersion obtained in Step 1 to dilute it.

[0035] From the viewpoint of production efficiency, in step 2, the aqueous dispersion obtained in step 1 may be diluted with water before adding the tetraalkoxysilane. The total amount of the fragrance compound and tetraalkoxysilane from step 1 relative to the total amount of the aqueous dispersion obtained in step 1 before dilution is preferably 3% by mass or more, more preferably 5% by mass or more, even more preferably 10% by mass or more, and even more preferably 15% by mass or more, and preferably 50% by mass or less, more preferably 40% by mass or less, and even more preferably 30% by mass or less. The dilution ratio is preferably 2 times or more, more preferably 2.5 times or more, and preferably 20 times or less, more preferably 10 times or less, and more preferably 7 times or less.

[0036] The reaction temperature for the sol-gel reaction in step 2 can be arbitrarily selected as long as it is above the melting point and below the boiling point of the water contained as the dispersion medium. However, from the viewpoint of controlling the balance between the hydrolysis reaction and the condensation reaction in the sol-gel reaction and forming a dense shell, it is preferably 5°C or higher, more preferably 10°C or higher, even more preferably 15°C or higher, and preferably 60°C or lower, more preferably 50°C or lower, and even more preferably 40°C. The sol-gel reaction in step 1 and the sol-gel reaction in step 2 may be carried out at different reaction temperatures.

[0037] In step 2 of the present invention, an organic polymer compound may be further added to the aqueous dispersion obtained in step 1 for the purpose of stabilizing the aqueous dispersion and suppressing aggregation. Here, an organic polymer compound means a compound with a weight-average molecular weight of 5,000 or more. Examples of the aforementioned organic polymer compounds include nonionic polymers, cationic polymers, and anionic polymers. The nonionic polymer refers to a water-soluble polymer that does not have an electric charge in water. By using a nonionic polymer, it is possible to impart functions to the silica capsule according to its intended use. When a nonionic polymer, cationic polymer, or anionic polymer is used as the organic polymer compound, for example, when the silica capsules according to the present invention are used in a fiber treatment composition such as a softener composition, an improvement in the adsorption of the silica capsules to fibers can be expected. In this specification, "water-soluble polymer" means a polymer that, when dried at 105°C for 2 hours to reach a constant weight, is dissolved in 100g of water at 25°C, and the amount dissolved is 1 mg or more.

Examples of nonionic monomers include (meth)acrylates having hydrocarbon groups derived from aliphatic alcohols with 1 to 22 carbon atoms; styrene monomers such as styrene; aromatic group-containing (meth)acrylates such as benzyl (meth)acrylate; vinyl acetate; vinylpyrrolidone; vinyl alcohol; polyalkylene glycol (meth)acrylates such as polyethylene glycol mono(meth)acrylate; alkoxy polyalkylene glycol mono(meth)acrylates such as methoxy polyethylene glycol mono(meth)acrylate and octoxy polyethylene glycol mono(meth)acrylate; and (meth)acrylamide. Note that (meth)acrylate means acrylate or methacrylate. Similarly, (meth)acrylic means acrylic or methacrylic.

[0039] Cationic polymers include polymers containing quaternary ammonium bases, polymers having nitrogen-based cationic groups, and polymers that may become cationic through pH adjustment. By using cationic polymers, the tendency of silica capsules (1) obtained in step 1 to aggregate in the aqueous dispersion can be mitigated, and the generation of coarse particles and the like can be suppressed in the subsequent step 2. Examples of cationic polymers include polydiallyldimethylammonium salts and copolymers thereof, such as poly(diallyldimethylammonium chloride), poly(co-diallyldimethylammonium acrylate), poly(acrylamide-co-diallyldimethylammonium chloride), and poly(acrylamide-co-acrylate-co-diallyldimethylammonium chloride), as well as poly(2-(methacryloyloxy)ethyltrimethylammonium chloride), polyethyleneimine, polyallylamine, cationized cellulose, cationized guar gum, cationized tara gum, cationized fenugreek gum, and cationized locust bing gum. Among these, polydiallyldimethylammonium salts and copolymers thereof are preferred, with one or more selected from poly(diallyldimethylammonium chloride), poly(co-diallyldimethylammonium acrylate), and poly(acrylamide-co-acrylate-co-diallyldimethylammonium chloride) being more preferred, and poly(diallyldimethylammonium chloride) being even more preferred.

[0040] The cationic group equivalent of the cationic polymer is preferably 1 meq / g or more, more preferably 3 meq / g or more, even more preferably 4.5 meq / g or more, and preferably 10 meq / g or less, even more preferably 8 meq / g or less, from the viewpoint of dispersibility of the silica capsule (1), suppression of the generation of coarse particles, and improvement of long-term retention. The cationic polymer may contain anionic groups, in which case the anionic group equivalent contained in the cationic polymer is preferably 3.5 meq / g or less, more preferably 2 meq / g or less, even more preferably 1 meq / g or less. In this invention, the cationic group equivalent of the cationic polymer is calculated based on the monomer composition.

[0041] Examples of anionic polymers include polymers containing monomer units having carboxyl groups, polymers containing monomer units having sulfonic acid groups, and polymers that become anionic when the pH is adjusted. Examples of anionic polymers include poly(meth)(acrylic acid), poly(maleic acid), poly((meth)acrylic acid-co-maleic acid), poly((meth)acrylic acid-co-maleic anhydride), poly((meth)acrylic acid-co-isobutylene), poly((meth)acrylic acid-co-styrene), poly(isobutylene-co-maleic acid), poly(styrene-co-maleic acid), and carboxymethylcellulose. Note that (meth)acrylic acid means acrylic acid or methacrylic acid.

[0042] The amount of organic polymer compound added is preferably 0.05% by mass or more, more preferably 0.1% by mass or more, even more preferably 0.2% by mass or more, and preferably 5% by mass or less, more preferably 3% by mass or less, and even more preferably 2% by mass or less, relative to the aqueous dispersion obtained in step 1.

[0043] The silica capsules obtained in step 2 are dispersed in water. Depending on the application, they can be used as is, but in some cases, the silica capsules may need to be separated before use. Separation methods include filtration and centrifugation.

[0044] <core> The core of the silica capsule according to the present invention contains a fragrance compound. In this invention, from the viewpoint of fragrance release when the fibers become wet with moisture such as perspiration, it is preferable that the proportion of fragrance compounds having a logP of 2.0 or more and a vapor pressure of 0.01 Pa or more and 8.00 Pa or less at 25°C is 25% by mass or more of the total amount of fragrance compounds.

[0045] In this invention, the logP value is a coefficient that indicates the affinity of an organic compound for water and 1-octanol. The 1-octanol / water partition coefficient P is the ratio of the equilibrium concentrations of the compound in each solvent when a trace amount of the compound dissolves as a solute in a solvent consisting of two liquid phases, 1-octanol and water, and reaches partition equilibrium. It is generally expressed in the form of its logarithm logP with respect to base 10. Today, the value of "calculated logP (sometimes called ClogP)", which is calculated by a calculation program that uses the fragment value of the atomic group determined by the number of atoms constituting the compound molecule and the type of chemical bond, is widely used, and in this invention as well, the value of ClogP is used when selecting compounds.

[0046] In this invention, the ClogP value is calculated using the EPI Suite (registered trademark; The EstimationsProgramsInterface for Windows version 4.11), software jointly developed by the U.S. Environmental Protection Agency and Syracuse.

[0047] In this invention, the vapor pressure at 25°C is determined by measurement or estimation from the boiling point, and is estimated from the melting point if the chemical substance is solid at room temperature. Vapor pressure can be estimated by several known methods (Antoine method, Modified Grain method, Mackay method, etc.), but in this invention, the value is calculated using MPBPWIN, which is incorporated into the EPI suite available from the U.S. Environmental Protection Agency (EPA).

[0064] [ka]

[0065] Here, with respect to component (b), alcohol-based fragrance compounds and phenol-based fragrance compounds may refer to compounds having an alcohol or phenol skeleton that are listed as fragrance components (fragrance materials) in publications such as books and literature. In addition, it may include compounds having an alcohol or phenol skeleton that persons in the relevant art know empirically to be usable as fragrance materials.

[0066] (b) The component is R in general formula (B1) 1b , R 2b , R 3b and R 4b Compounds in which all are the same group, and R 1b , R 2b , R 3b and R 4b There are compounds in which some or all of the groups are different, and either can be used. Also, the R in general formula (B2) 1b’ , R 2b’ , R 3b’ and R 4b’ Compounds in which all are the same group, and R 1b’ , R2b’ , R 3b’ and R 4b’ There are compounds in which some or all of the groups are different, and any of them can be used.

[0067] (b1) The components will be explained. (b1) With respect to the component, an alcohol compound used as a fragrance that has a hydroxyl group on the carbon atom at the allyl position and that carbon atom is a primary carbon atom will be hereinafter referred to as a "primary allyl alcohol fragrance." Also, an alcohol compound used as a fragrance that has a hydroxyl group on the carbon atom at the allyl position and that carbon atom is a secondary carbon atom will be hereinafter referred to as a "secondary allyl alcohol fragrance." When referring to "allyl alcohol fragrance," both "primary allyl alcohol fragrances" and "secondary allyl alcohol fragrances" are included.

[0068] Therefore, the term "allyl alcohol fragrance" as used herein refers to an alcohol fragrance that is also used as a fragrance and is a so-called allyl alcohol compound having a hydroxyl group at the allyl position.

[0069] (b1)Specific examples of allyl alcohol fragrances that make up the components include primary allyl alcohol fragrances such as geraniol, nerol, cis-2-hexenol, trans-2-hexenol, 3-phenyl-2-propen-1-ol (cinnamic alcohol), 2-ethyl-4-(2,2,3-trimethyl-3-cyclopenten-1-yl)-2-buten-1-ol (bakudanol), 2-methyl-4-(2,2,3-trimethyl-3-cyclopenten-1-yl)-2-buten-1-ol (sandal mysol coir), 3,7,11-trimethyl-2,6,10-dodecatrien-1-ol (farnesol), and 2-methyl-5-(2,3-dimethyltricyclo[2.2.1.0 2,6Examples include heptane-3-yl)-2-penten-1-ol (santalol), and as secondary allyl alcohol fragrances, examples include 4-methyl-3-decen-5-ol (undecapertol) and 1-octen-3-ol. Among these, fragrance compounds selected from geraniol, nerol, undecapertol, and sandalmysolcore are preferred as fragrances with a high lifting effect that enhances the fragrance from the surface of the fibers.

[0070] (b1) The component is R in general formula (B1) 1b , R 2b , R 3b and R 4b In addition to residues of allyl alcohol compounds contained in allyl alcohol fragrances, the fragrance may have a hydrogen atom or a hydrocarbon group having 1 to 30 carbon atoms, which may have a substituent (excluding residues obtained by removing the phenolic hydroxyl group from a phenol compound used as a fragrance). Examples of hydrocarbon groups having 1 to 30 carbon atoms include aliphatic hydrocarbon groups having 1 to 30 carbon atoms, which may have a substituent, and aralkyl groups having 7 to 30 carbon atoms, which may have a substituent. Examples of aliphatic hydrocarbon groups include saturated aliphatic hydrocarbon groups and unsaturated aliphatic hydrocarbon groups.

[0071] Examples of substituents that the aliphatic hydrocarbon group or aralkyl group may have include alkyl groups having 1 to 10 carbon atoms, alkenyl groups having 2 to 10 carbon atoms, alkoxy groups having 1 to 10 carbon atoms, or acyl groups having 2 to 10 carbon atoms, which may be interrupted by ester bonds, amide bonds, ether bonds, etc.

[0072] As a hydrocarbon group having 1 to 30 carbon atoms, which may have substituents, a residue obtained by removing a hydroxyl group from an alcohol compound used as a fragrance (hereinafter referred to as "alcoholic fragrance") (hereinafter referred to as "alcoholic fragrance residue") is preferred. Although the concept of alcoholic fragrance residue includes the allyl alcoholic fragrance residue mentioned above, in component (b1), it is used separately from a rational viewpoint for explaining the structure of general formula (B1).

[0073] From the viewpoint of providing a moderately long-lasting fragrance, the hydrocarbon group is preferably a residue obtained by removing a hydroxyl group from a primary alcohol having 1 or more carbon atoms, more preferably 2 or more carbon atoms, and more preferably 20 or less carbon atoms, and more preferably 18 or less carbon atoms. Specific examples of primary alcohols include lower alcohols such as ethanol and butanol; higher alcohols such as lauryl alcohol, myristyl alcohol, palmityl alcohol, and stearyl alcohol; and Guerbet alcohols such as 2-ethylhexanol and 4-butyloctanol. Alcoholic fragrance residues are also included among the residues obtained by removing a hydroxyl group from a primary alcohol having 1 to 20 carbon atoms.

[0074] As mentioned above, component (b1) is R in general formula (B1) 1b , R 2b , R 3b and R 4b It is preferable that two or more, three or more, four or fewer, and four of these are allyl alcohol fragrance residues. Furthermore, it is more preferable that the allyl alcohol fragrance is an allyl alcohol fragrance obtained from geraniol, nerol, undecabertol, and sandalmysol core.

[0075] (b1) The following combinations can be used as components. A mixture of each group may also be used. That is (b1-1) Component: A compound represented by the general formula (B1), R 1b , R 2b , R 3b and R 4b The compound consists of one to three allyl alcohol fragrance residues, preferably selected from geraniol, nerol, undecaverthol, and sandalmysolcore, with the remaining residues independently being a hydrogen atom, an aliphatic hydrocarbon group having 1 to 30 carbon atoms (which may have substituents), or an aralkyl group having 7 to 30 carbon atoms (which may have substituents).

(b1-5) Components: Compounds represented by general formula (B1), R 1b , R 2b , R 3b and R 4bOne to two of these are allyl alcohol fragrance residues, preferably selected from geraniol, nerol, undecaverthol, and sandalmysolcore, and one or two are independently alcohol fragrance residues having 1 to 30 carbon atoms, and one or two are compounds selected from alcohol fragrance residues other than primary alcohols having 1 to 20 carbon atoms, and more preferably the primary alcohol is a lower alcohol such as ethanol or butanol; a higher alcohol such as lauryl alcohol, myristyl alcohol, palmityl alcohol, or stearyl alcohol; or a Guerbet alcohol such as 2-ethylhexanol or 4-butyloctanol.

That is the case.

[0076] Next, we will explain component (b2). (b2) The phenolic fragrance of the present invention that constitutes the component refers to an aromatic compound having a hydroxyl group as a substituent on an aromatic ring and being used as a fragrance, and does not mean phenol itself. In addition, some literature classifies phenolic fragrances as alcoholic fragrances in the fragrance classification, but in the present invention, they are treated as different fragrance compounds.

[0077] Specific examples of phenolic fragrances include 4-(3-oxobutyl)phenol (raspberry ketone), eugenol, isoeugenol, 4-hydroxy-3-methoxybenzaldehyde (vanillin), 3-ethoxy-4-hydroxybenzaldehyde (ethyl vanillin), thymol, carvacrol, and 3-methyl-4-isopropylphenol. Among these, fragrance compounds selected from raspberry ketone, vanillin, and ethyl vanillin are preferred because they can continuously impart a refreshing, sweet scent to the surface of the fibers.

[0078] Regarding phenolic fragrance residues, the residues obtained by removing the phenolic hydroxyl group from a phenolic fragrance refer to residues from which the hydroxyl group substituted on the aromatic ring has been removed.

[0079] (b2) The component is R in general formula (B2) 1b’ , R 2b’ , R 3b’ and R 4b’ In addition to phenolic fragrance residues, the compound may have a hydrogen atom or a hydrocarbon group having 1 to 30 carbon atoms (excluding phenolic fragrance residues), which may have a substituent. Examples of hydrocarbon groups having 1 to 30 carbon atoms include aliphatic hydrocarbon groups having 1 to 30 carbon atoms, which may have a substituent, and aralkyl groups having 7 to 30 carbon atoms, which may have a substituent. Examples of aliphatic hydrocarbon groups include saturated aliphatic hydrocarbon groups and unsaturated aliphatic hydrocarbon groups.

[0080] Examples of substituents that the aliphatic hydrocarbon group or aralkyl group may have include alkyl groups having 1 to 10 carbon atoms, alkenyl groups having 2 to 10 carbon atoms, alkoxy groups having 1 to 10 carbon atoms, or acyl groups having 2 to 10 carbon atoms, which may be interrupted by ester bonds, amide bonds, ether bonds, etc.

The other organic group is a residue other than an alcoholic fragrance residue or a phenolic fragrance residue, and examples thereof include the above-mentioned primary alcohol.

[0084] The alcoholic fragrances constituting component (b2) can be classified based on whether the carbon atom to which the hydroxyl group is bonded is a primary carbon atom, a secondary carbon atom, or a tertiary carbon atom. Furthermore, component (b2) may also contain groups selected from the following alcoholic fragrance residues.

Then, 30g of deionized water was added, followed by 2g of sodium polyoxyethylene lauryl ether sulfate with an average addition of 2 moles, and 15g of polyoxyethylene myristyl ether with an average addition of 40 moles. Stirring continued under high shear force for another 30 minutes, and then 248g of water was added and stirred to obtain an aqueous emulsion of dimethylpolysiloxane [(h1)]. The volume-average particle size of the emulsion particles in (h1) was 500nm. The dimethylpolysiloxane content in (h1) was 50% by mass. The volume-average particle size was measured at 20°C using an electrophoretic light scattering photometer (Otsuka Electronics Co., Ltd., model ELS-8000) after dispersing the aqueous emulsion in ethanol.

[0191] <(k) component> The following two compounds were used as component (k): (k1): Propylene glycol (k2): Ethylene glycol

[0192] <(l) component> (l) Trisodium methylglycine diacetate (l1) was used as the component.

[0193] <(n) component> (n) Proxel BDN (manufactured by Arch Chemical Japan, n1) was used as component (n).

[0194] <(o) component> (o) Calcium chloride (o1) was used as the component.

[0195] <(i) Components> Hydrochloric acid was used.

[0196] <Examples and Comparative Examples> [Preparation of textile product treatment agent composition] Textile product treatment agent compositions were prepared by mixing each component to achieve the formulation shown in Table 3. Specifically, the composition is as follows. Note that the mass percentages in the table represent the mass percentage of the effective portion. In a 300 mL beaker, an amount of deionized water equivalent to 85% by mass of the amount required to produce 200 g of the textile product treatment agent composition was added, along with hydrochloric acid as components (e), (h), (k), (l), (n), and (i) as needed. The temperature of the deionized water was adjusted to 60 ± 2 °C using a water bath. A mixture was obtained by stirring with a stirring blade as needed to ensure that the added components in the aqueous layer dissolved uniformly in the deionized water. The stirring blade used was one with three blades, whose long side was positioned at a 90-degree angle to the rotational axis of a 5 mm diameter stirring rod, with a long side / short side ratio of 3 cm / 1.5 cm, and the blades positioned at a 45-degree angle to the rotational surface.

[0197] The mixture, heated to a temperature of 60±2℃, was stirred with the aforementioned stirring blade (300 rpm). Component (c), which had been heated and dissolved at 65℃, and optionally component (g), were added over a period of 3 minutes. After the addition was complete, the mixture was stirred for 15 minutes. Next, the mixture was cooled using a 5°C water bath until its temperature reached 30±2°C. Components (a), and optionally (b), (d), and (o) were added sequentially and stirred for 5 minutes. Furthermore, deionized water was added to achieve the final mass (200g), and the mixture was stirred for another 5 minutes to obtain the textile product treatment agent composition. The pH was adjusted as appropriate with an aqueous NaOH solution. The pH of the liquid fiber product treatment agent composition was measured as follows. A pH measuring composite electrode (HORIBA general-purpose sleeve type) was connected to a pH meter (HORIBA pH meter D-51), and the power was turned on. A saturated potassium chloride aqueous solution (3.33 mol / L) was used as the internal solution for the pH electrode. Next, 100 ml beakers were filled with pH 1.68 standard solution (oxalate standard solution), pH 4.01 standard solution (phthalate standard solution), and pH 6.86 (neutral phosphate standard solution), and immersed in a 30°C constant temperature bath for 30 minutes. The pH measuring electrode was immersed in the standard solutions adjusted to constant temperature for 3 minutes, and the calibration procedure was performed in the order of pH 6.86 → pH 4.01 → pH 1.68. When measuring in the alkaline range, a pH 9.18 standard solution (borate standard solution) is used instead of the pH 1.68 standard solution for calibration. The sample was filled into a 100 ml beaker and adjusted to 30°C in a 30°C constant temperature bath. The pH was measured by immersing a pH measuring electrode in the sample adjusted to constant temperature for 3 minutes.

[0198] The visible light transmittance of the obtained textile product treatment agent compositions was measured. Specifically, a glass cell with a path length of 10 mm was used as the measurement cell, deionized water was placed in the control cell, and the measurement was performed using a UV-Vis spectrophotometer (Shimadzu UV-2500PC). The visible light transmittance (wavelength 660 nm) of the textile product treatment agent compositions obtained in the examples and comparative examples was all less than 10%, indicating that they were emulsion-type textile product treatment agent compositions.

[0199] <Fragrance Evaluation> Beforehand, 17 pieces of underwear (Gunze Co., Ltd., men's crew neck short-sleeved shirts, size L) were washed five times in a Hitachi NW-6CY fully automatic washing machine using a commercially available weakly alkaline detergent (Kao Corporation, Attack), and excess detergent was removed by drying indoors. The washing conditions for each wash were: detergent concentration 0.0667% by mass, 47L of tap water, water temperature 20℃, wash for 10 minutes, rinse twice, and spin dry for 6 minutes.

[0200] In a Panasonic Corporation electric bucket N-BK2-A, 0.867g (10g / 1.5kg of underwear) of the textile product treatment agent composition, which had undergone the above storage conditions, was added to 4L of tap water. Then, one piece of underwear washed using the method described above was added, and the mixture was agitated for 5 minutes. After that, the underwear treated with the liquid fabric softener composition was spun dry for 3 minutes in the spin-drying tub of a Hitachi, Ltd. twin-tub washing machine, and then hung on a hanger in a room at 20°C and 40% RH to dry for 24 hours. This procedure was repeated three times for each liquid fabric softener composition, and five pieces of underwear treated with each composition were prepared.

[0201] The effectiveness of the fragrance was evaluated using the following method. One of the prepared undergarments was folded and stored in a room at 20°C / 60%RH for three days. A 20cm x 20cm piece of fabric was cut from the stored undergarment and used for fragrance evaluation. The evaluation method involved first smelling the fabric in its dry state, then moistening the fabric with 10-20% owf water using a spray, and then folding the fabric into quarters. After letting it stand for a few seconds, the fabric was unfolded and the scent at the intersection of the folds was smelled to evaluate the difference in fragrance intensity between the dry and wet states and the expressiveness of the fragrance, which was used to determine the effectiveness of moisture-induced fragrance release. The evaluation was conducted by five panelists specializing in fragrance evaluation. The evaluation was conducted using a sample treated with the formulation of Comparative Example 2, as shown in Table 3, as a reference (score 1), according to the following criteria, and the average of the evaluations from five people was used as the evaluation result. <Evaluation Criteria> Differences in fragrance intensity Score 3: Compared to the reference, I noticed a difference in fragrance intensity. Score 2: Compared to the reference, there is a slight difference in aroma intensity. Score 1: Compared to the reference, I perceive a similar difference in fragrance intensity. <Evaluation Criteria> The expressive power of scent Score 3: Compared to the reference, it has a richer and fresher scent. Score 2: Compared to the reference, it has a slightly richer yet fresher scent. Score 1: Compared to the reference, it has a similarly rich yet fresh aroma.

[0202] [Table 3]

[0203] The composition in Comparative Example 2 that did not contain component (a) had the lowest fragrance effectiveness among the examples and comparative examples, and was used as the reference (score 1). Comparative Example 1, which contained component (a) but did not contain component (b), had a higher fragrance effectiveness compared to Comparative Example 2. On the other hand, Examples 1 to 8, which included both component (a) and component (b), all showed a higher level of effectiveness than Comparative Examples 1 and 2.
