Description

Technical Field

[0001] The present invention relates to a fiber product treatment agent.

Background Art

[0002] In recent years, the domestic share of products among fiber product treatment agents (such as detergents and fabric softeners) that appeal for a deodorizing function has been increasing year by year. In order to prevent the adhesion of odors such as sweat odor to fiber products, a technique of blending benzyl benzoate into a fabric softener is known (Patent Document 1). In order to obtain an anti-odor composition excellent in body odor suppression effect, a technique of using a specific type of plant extract in combination is known (Patent Document 2). In order to obtain a formulated fragrance excellent in masking effect and deodorizing effect, a technique of using top note, middle note and base note in combination is known (Patent Document 3). In order to effectively mask the odor derived from a cleaning liquid, a technique of blending a specific combination of fragrances into a laundry detergent is known (Patent Document 4). In addition, there is also a deodorizing technique (masking by fragrance) that utilizes the fragrance of a fiber product treatment agent, but there is also a concern that the fragrance remaining on the fiber product (residual fragrance property) is too strong (smehara).

[0044] Cationic surfactants are well-known substances and are readily available on the market or can be prepared. Cationic surfactants may be used individually or in combination of multiple types (for example, a mixture of compounds represented by general formulas (A1-3) to (A1-5)).

[0045] The content of the cationic surfactant is not particularly limited as long as the purpose of formulation is achieved, but is preferably 5 to 30% by mass, more preferably 8 to 25% by mass, and especially preferably 10 to 23% by mass, based on the total mass of the liquid softener.

[0046] [Nonionic surfactants] Nonionic surfactants are added to liquid fabric softeners to improve the emulsification and dispersion stability of oil-soluble components and to impart freeze-recovery properties. As nonionic surfactants, any substance known in the field of liquid fabric softeners can be used without particular limitations. For example, alkylene oxide adducts of alcohols or fatty acids can be used. Each carbon chain portion of the alcohol and fatty acid may be linear or branched, and may contain unsaturated groups. The carbon chain may also have a distribution. The number of carbon atoms in the carbon chain is preferably 6 to 20, more preferably 8 to 18. If the carbon chain is linear, the number of carbon atoms is preferably 6 to 14, more preferably 8 to 12, and particularly preferably 10 to 12. If the carbon chain is branched, the number of carbon atoms is preferably 6 to 18, more preferably 9 to 18, and particularly preferably 13. As raw materials for nonionic surfactants, you can use Exal from ExxonMobil, the Lutenzol series from BASF, Oxocol from Kyowa Hakko Kogyo, and the DOBANOL series from Shell. When the nonionic surfactant is an alkylene oxide adduct of an alcohol, either primary or secondary alcohols can be used. A C13 alcohol can be produced, for example, using dodecene as a starting material, but the starting material can be either butylene or propylene. If the carbon chain contains an unsaturated group, it is particularly preferable that the number of carbon atoms is 18. The stereoisomer structure of the unsaturated group may be the cis isomer, the trans isomer, or a mixture of both, but the ratio of the cis / trans isomer is preferably 25 / 75 to 100 / 0 (by mass). Ethylene oxide (EO) is preferred as the alkylene oxide, but propylene oxide (PO) or butylene oxide (BO) may be added together with EO. The average number of moles of EO added is preferably 10 to 100 moles, more preferably 20 to 80 moles, and particularly preferably 40 to 70 moles. The average number of moles of PO or BO added together with EO is preferably 1 to 5, more preferably 1 to 3 moles. In this case, PO or BO may be added after EO, ​​or EO may be added after PO or BO.

[0047] Examples of nonionic surfactants include nonyl alcohol with an average of 9 moles of EO and an average of 1 mole of PO added, a primary isononyl alcohol adduct with an average of 40 moles of EO, a primary isodecyl alcohol adduct with an average of 20 moles of EO, a lauryl alcohol adduct with an average of 10 to 100 moles (preferably 20 to 30 moles) of EO, a primary isohexadecyl alcohol adduct with an average of 60 moles of EO, a primary isotridecyl alcohol adduct with an average of 10 to 100 moles (preferably 60 moles) of EO, a tridecyl alcohol adduct with an average of 50 moles of EO, and a lauric acid adduct with an average of 20 moles of EO. Commercially available products include the Emarex series from Nippon Emulsion, the Emarumin series from Sanyo Chemical Industries, the TDA series from Lion Chemical Industries, the Softanol series from Nippon Shokubai, and the LUTESOL series from BASF.

[0048] Nonionic surfactants are known substances and are readily available on the market or can be prepared. Nonionic surfactants may be used individually or in combination of multiple types.

[0049] The content of the nonionic surfactant is not particularly limited as long as the formulation objective is achieved, but is preferably 0.01 to 10% by mass, more preferably 0.1 to 8% by mass, and especially preferably 0.5 to 5% by mass, relative to the total mass of the liquid softener. A content of 10% by mass or less yields a viscosity with excellent usability.

[0050] [Viscosity modifier] Viscosity modifiers are added to improve the usability of liquid fabric softeners. Examples of viscosity modifiers include calcium chloride, magnesium chloride, sodium chloride, sodium p-toluenesulfonate, and sodium citrate. Calcium chloride is preferred among these. A single type of viscosity modifier may be used, or multiple types may be used in combination. The viscosity modifier content is 0.001 to 5% by mass, preferably 0.003 to 3% by mass, and more preferably 0.005 to 1% by mass, relative to the total mass of the liquid softener.

[0051] [Cyclic dextrin compounds] Cyclic dextrin compounds are added to further improve the deodorizing properties of textile products. Cyclic dextrin compounds are glucans having a cyclic structure with a degree of polymerization (n) of 5 or more. Examples include common cyclodextrins such as α-cyclodextrin (n=6), β-cyclodextrin (n=7), and γ-cyclodextrin (n=8), which have 6 to 8 glucose units linked together, as well as highly branched cyclic dextrins that have an internally branched cyclic structure and an externally branched structure. The internally branched cyclic structure refers to the cyclic structure formed by α-1,4-glucosidic bonds and α-1,6-glucosidic bonds, while the externally branched structure refers to the acyclic structure bonded to the internally branched cyclic structure. Highly branched cyclic dextrins mainly consist of dextrins with a weight-average degree of polymerization of about 2500, in which numerous acyclic branched glucan chains (external branched structural portions) are bonded to one internally branched cyclic structure, and have a molecular weight of about 30,000 to 1,000,000. The internally branched cyclic structure is composed of approximately 10 to 100 glucose molecules. The degree of polymerization of highly branched cyclic dextrins is, for example, 50 to 5000. The degree of polymerization of the internally branched cyclic structure is, for example, 10 to 100. The degree of polymerization of the outer branched structure is, for example, 40 or higher. The degree of polymerization of each unit chain in the outer branched structure is, for example, 10 to 20 on average. Highly branched cyclic dextrins can be produced, for example, by reacting starch with a blanching enzyme. The raw material starch consists of amylose, in which glucose is linked linearly by α-1,4-glucosidic bonds, and amylopectin, which has a complex branched structure by α-1,6-glucosidic bonds. Amylopectin is a macromolecule in which many cluster structures are linked together. The blanching enzyme is a glucan transferase widely distributed in plants, animals, and microorganisms, and it acts on the junctions of the amylopectin cluster structure, catalyzing the reaction that cyclicizes it. Specific examples of highly branched cyclic dextrins include glucans having an internally branched cyclic structure portion and an externally branched structure portion, as described in Japanese Patent Publication No. 8-134104, with a degree of polymerization of 50 to 10000, and "Cluster Dextrin" (registered trademark) of Glico Nutrition Foods Co., Ltd. A single type of cyclic dextrin compound may be used, or multiple types may be used in combination. The content of the cyclic dextrin compound is not particularly limited as long as the purpose of formulation is achieved, but is preferably 0.01 to 10% by mass, more preferably 0.1 to 5% by mass, and especially preferably 0.1 to 2% by mass, relative to the total mass of the liquid softener.

As the water-soluble solvent, one or more selected from the group consisting of lower (C1-C4) alcohols, glycol ether solvents, and polyhydric alcohols are preferred. Specifically, those selected from the group consisting of ethanol, isopropanol, glycerin, ethylene glycol, propylene glycol, diethylene glycol, dipropylene glycol, hexylene glycol, polyoxyethylene phenyl ether, and compounds represented by general formula (X) are preferred. R 11 -O-(C2H4O) y -(C3H6O) z -H ···(X) In general formula (X), R 11 is an alkyl or alkenyl group having 1 to 6 carbon atoms (preferably 2 to 4). y and z are the average number of moles added, where y is 1 to 10, preferably 2 to 5, and z is 0 to 5, preferably 0 to 2.

A single type of water-soluble solvent may be used, or multiple types may be used in combination. The content of the water-soluble solvent is not particularly limited as long as the purpose of the formulation is achieved, but is preferably 0 to 30% by mass, more preferably 0.01 to 25% by mass, and especially preferably 0.1 to 20% by mass, relative to the total mass of the liquid softener.

[0053] [Silicone compounds] Silicone compounds are added to further improve the deodorizing properties of textile products. Any silicone compound known in the field of liquid softeners can be used without particular limitations. The silicone compound may be linear, branched, or crosslinked. The silicone compound may be a modified silicone compound that has been modified with one or more organic functional groups. The silicone compound may be an oil or an emulsion dispersed with an emulsifier. Examples of silicone compounds include dimethyl silicone, polyether-modified silicone, methylphenyl silicone, alkyl-modified silicone, higher fatty acid-modified silicone, methyl hydrogen silicone, fluorine-modified silicone, epoxy-modified silicone, carboxy-modified silicone, carbinol-modified silicone, and amino-modified silicone. From the viewpoint of formulation purpose and versatility, polyether-modified silicone, amino-modified silicone, and dimethyl silicone are preferred. From the viewpoint of formulation purpose and handling during manufacturing, polyether-modified silicone and amino-modified silicone are preferred. Examples of polyether-modified silicones include copolymers of alkylsiloxanes and polyoxyalkylenes. The alkyl group of the alkylsiloxane preferably has 1 to 3 carbon atoms, and the alkylene group of the polyoxyalkylene preferably has 2 to 5 carbon atoms. As the polyether-modified silicone, a copolymer of dimethylsiloxane and polyoxyalkylene (such as polyoxyethylene, polyoxypropylene, or random or block copolymers of ethylene oxide and propylene oxide) is preferred.

[0054] An example of a polyether-modified silicone is a polyether-modified silicone represented by the following general formula (I). [ka] In general formula (I), R represents hydrogen or an alkyl group, preferably hydrogen or an alkyl group having 1 to 4 carbon atoms. M, N, a, and b represent the average degree of polymerization. M is preferably 10 to 10,000, and more preferably 100 to 300. N is preferably 1 to 1,000, and more preferably 1 to 100. Furthermore, it is preferable that M > N. a is preferably 2 to 100, and more preferably 2 to 50. b is preferably 0 to 50, and more preferably 0 to 10. Polyether-modified silicones represented by general formula (I) are generally produced by subjecting an organohydrogenpolysiloxane having Si-H groups to a polyoxyalkylene alkyl ether having a carbon-carbon double bond at its terminus, such as polyoxyalkylene allyl ether, in an addition reaction under platinum catalyst. Therefore, polyether-modified silicones may contain small amounts of unreacted polyoxyalkylene alkyl ether or organohydrogenpolysiloxane having Si-H groups. Since organohydrogenpolysiloxane having Si-H groups is highly reactive, its presence in the polyether-modified silicone is preferably 30 ppm or less (as the amount of Si-H).

[0055] Examples of polyether-modified silicones include linear polysiloxane-polyoxyalkylene block copolymers, which are generally represented by (II) below. [ka] In general formula (II), R represents an alkyl group, preferably an alkyl group having 1 to 5 carbon atoms. R' represents hydrogen or an alkyl group, preferably hydrogen or an alkyl group having 1 to 4 carbon atoms. A, B, h, and i are the average degrees of polymerization. A is preferably 5 to 10,000, B is preferably 2 to 10,000, h is preferably 2 to 100, and i is preferably 0 to 50. A linear polysiloxane-polyoxyalkylene block copolymer represented by general formula (II) can be produced by reacting a polyoxyalkylene compound having a reactive end group with a dihydrocarbylsiloxane having an end group that reacts with the reactive end group of the compound. The viscosity of this copolymer increases as the polyoxyalkylene side chains become longer and the degree of polymerization of the polysiloxane chains increases. Therefore, to improve workability during production and facilitate blending into aqueous compositions, it is preferable to blend it in the form of a premix with a water-soluble organic solvent. Examples of water-soluble organic solvents include ethanol, dipropylene glycol, and butyl carbitol.

Amino-modified silicones may be silicone oils obtained by introducing amino groups to the terminal or side chains of a dimethyl silicone skeleton. They may also be substituted with substituents other than amino groups (such as hydroxyl groups, alkyl groups, or phenyl groups). Amino-modified silicones can be oils or emulsions dispersed with emulsifiers (nonionic surfactants or cationic surfactants). The preferred base oil of the amino-modified silicone oil or emulsion has a structure represented by general formula (III).

Among these, at least one anionic surfactant selected from linear alkylbenzene sulfonic acid or its salts, alkane sulfonates, polyoxyethylene alkyl ether sulfates, and α-olefin sulfonates is more preferred, and polyoxyethylene alkyl ether sulfates are particularly preferred. Other anionic surfactants can also be used. Specific examples include carboxylic acid-type anionic surfactants such as higher fatty acids with 10 to 20 carbon atoms or their salts, alkyl ether carboxylates, polyoxyalkylene ether carboxylates, alkyl (or alkenyl) amide ether carboxylates, and acylaminocarboxylates; and phosphate ester-type anionic surfactants such as alkyl phosphate esters, polyoxyalkylene alkyl phosphate esters, polyoxyalkylene alkylphenyl phosphate esters, and glycerin fatty acid ester monophosphate esters. Anionic surfactants are well-known substances and are readily available on the market or can be prepared. Anionic surfactants may be used individually or in combination of multiple types.

[0076] It is preferable to use an anionic surfactant having an SO3 group or an SO4 group in combination with a fatty acid (higher fatty acid) having 8 to 22 carbon atoms or a salt thereof (higher fatty acid salt) as the anionic surfactant. Examples of higher fatty acids include single fatty acids such as caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, isostearic acid, hydroxystearic acid, oleic acid, and behenic acid, as well as mixed fatty acids such as coconut oil fatty acids and beef tallow fatty acids. Examples of higher fatty acid salts include alkali metal salts such as sodium salts and potassium salts, alkanolamine salts such as ammonium salts, monoethanolamine salts, diethanolamine salts, triethanolamine salts, 2-amino-2-methylpropanol salts, and 2-amino-2-methylpropanediol, and basic amino acid salts such as lysine and arginine.

[0077] [Nonionic surfactants] Examples of nonionic surfactants that can be used without particular restriction from substances known in the field of detergents for textile products include polyoxyalkylene-type nonionic surfactants, alkylphenols, alkylene oxide adducts of fatty acids having 8 to 22 carbon atoms or amines having 8 to 22 carbon atoms, polyoxyethylene polyoxypropylene block copolymers, fatty acid alkanolamines, fatty acid alkanolamides, polyhydric alcohol fatty acid esters or their alkylene oxide adducts, polyhydric alcohol fatty acid ethers, alkyl (or alkenyl)amine oxides, alkylene oxide adducts of hydrogenated castor oil, sugar fatty acid esters, N-alkyl polyhydroxy fatty acid amides, alkyl glycosides, and the like. When the detergent is a liquid, a polyoxyalkylene-type nonionic surfactant that can maintain its viscosity appropriately while improving appearance stability is preferred. Examples of polyoxyalkylene-type nonionic surfactants include compounds represented by general formula (b-1) (hereinafter referred to as "compound (b1)") and compounds represented by the following general formula (b-2) (hereinafter referred to as "compound (b2)"). R 51 -CO-(OR 52 )m-OR 53 ...(b-1) R 54 -O-[(EO)s / (PO)t]H ···(b-2) In formula (b-1), R 51 R is a hydrocarbon group having 9 to 13 carbon atoms. 52 R is an alkylene group having 2 to 4 carbon atoms. 53 is an alkyl group having 1 to 4 carbon atoms. m is OR 52represents the average number of repetitions, which is 5 to 25. A plurality of R 52 may be the same as or different from each other. A plurality of R 52 When they are different, they may be added in a block form or randomly added. In formula (b-2), R 54 is a hydrocarbon group having 10 to 22 carbon atoms, EO is an oxyethylene group, and PO is an oxypropylene group. s represents the average number of repetitions of EO, which is 5 to 20, and t represents the average number of repetitions of PO, which is 0 to 4. EO and PO may be added in a block form or randomly added. From the points such as enhancing the detergency against sebum dirt and being less likely to gel in a high-concentration region, at least one selected from the group consisting of compound (b1) and (b2) is preferred. A combined use of compound (b1) and (b2) or a single use of compound (b1) is more preferred. When the detergent is liquid, at least one selected from the group consisting of compound (b1) and (b2) is preferred from the point of being less likely to gel in a high-concentration region. A combined use of compound (b1) and (b2) or a single use of compound (b1) is more preferred.

[0078] As compound (b1), polyoxyethylene fatty acid alkyl ester in which R 52 is an ethylene group is preferred, and among them, polyoxyethylene fatty acid methyl ester in which R 53 is a methyl group (hereinafter also referred to as "MEE") is particularly preferred. Liquid detergents containing polyoxyethylene fatty acid alkyl esters exhibit good solubility in water and high cleaning power. Furthermore, even when polyoxyethylene fatty acid alkyl esters are added at high concentrations, they do not significantly increase viscosity (gelling), resulting in a concentrated liquid detergent with good fluidity. The reasons for this are as follows: Polyoxyethylene fatty acid alkyl esters have high solubility in water and exhibit good fluidity at high concentrations. Therefore, when the liquid detergent is added to water, the concentration of polyoxyethylene fatty acid alkyl esters in the washing solution quickly becomes uniform, allowing it to come into contact with textile products at the predetermined concentration from the beginning of washing, thus exhibiting high cleaning power. In addition, polyoxyethylene fatty acid alkyl esters (especially MEE) have weak molecular orientation in aqueous solutions, and their micelles are unstable, making gelling less likely even at high concentrations, thus allowing for large amounts to be added on their own. As compound (b2), primary alcohol ethoxylates obtained by adding ethylene oxide to a primary alcohol are particularly preferred.

[0079] [Cationic surfactants] As cationic surfactants, any substance known in the field of detergents for textile products can be used without particular restriction. Specific examples include cationic surfactants such as alkyltrimethylammonium salts, dialkyldimethylammonium salts, alkylbenzyldimethylammonium salts, and alkylpyridinium salts. Other examples of cationic surfactants include long-chain aliphatic amide alkyl tertiary amines or salts thereof, such as caprylic acid dimethylaminopropylamide, capric acid dimethylaminopropylamide, laurate dimethylaminopropylamide, myristate dimethylaminopropylamide, palmitate dimethylaminopropylamide, stearate dimethylaminopropylamide, behenate dimethylaminopropylamide, and oleate dimethylaminopropylamide; and palmitate diethanolaminopropylamide and stearate diethanolaminopropylamide. The molecular weight of the cationic surfactant is preferably less than 1000.

[0080] [Amphoteric surfactants] As amphoteric surfactants, any substance known in the field of detergents for textile products can be used without particular restriction. Specific examples include alkylbetaine type, alkylamidebetaine type, imidazoline type, alkylaminosulfone type, alkylaminocarboxylic acid type, alkylamidecarboxylic acid type, amide amino acid type, and phosphoric acid type amphoteric surfactants.

[0081] A single type of surfactant may be used, or multiple types may be used in combination. Due to their high cleaning performance, anionic surfactants and nonionic surfactants are preferred, and a combination of anionic and nonionic surfactants is even more preferred. The surfactant content is not particularly limited as long as the formulation objective is achieved, but is preferably 15 to 79% by mass, more preferably 20 to 60% by mass, and especially preferably 30 to 55% by mass, relative to the total mass of the detergent. Within these content ranges, in addition to the formulation effect, improved re-soiling prevention is obtained. The content of the anionic surfactant is preferably 1 to 30% by mass, more preferably 5 to 20% by mass, and particularly preferably 7 to 15% by mass, relative to the total mass of the detergent. Within this content range, in addition to the blending effect, improved solubility of the fragrance composition and improved re-soiling prevention are obtained. The content of the nonionic surfactant is preferably 10 to 50% by mass, more preferably 10 to 40% by mass, and particularly preferably 15 to 30% by mass, relative to the total mass of the detergent. Within this content range, in addition to the blending effect, improved solubility and usability of the fragrance composition can be obtained.

[0082] [Optional ingredients] Known ingredients that can be incorporated into detergents for textile products can be used without particular restriction. Specific examples include cationic polymers, cleaning builders, dyes, fluorescent whitening agents, bleaches, bleach activators, bleach activation catalysts, enzymes, enzyme stabilizers, polymers, caking inhibitors, defoamers, preservatives, reducing agents, metal ion scavengers (chelating agents), clay minerals, UV absorbers, antioxidants, color transfer inhibitors, re-soiling inhibitors, pearlescent agents, soil release agents, hydrotropes, pH adjusters, water, and organic solvents.

[0083] [Formulation and physical properties of detergents] The detergent can be in solid or liquid form. Examples of solid detergents include granular (powder, granule) detergents, tablet detergents, briquette detergents, bar detergents, and individual-package detergents made by packaging granular or paste detergents in water-soluble films or sheets. The pH of the liquid detergent is not particularly limited, but it is preferably adjusted to 5-9, and more preferably 6-8, at 25°C. For pH adjustment, sulfuric acid, hydrochloric acid, sodium hydroxide, potassium hydroxide, or alkanolamines can be used.

[0084] [Method of manufacturing detergent] Detergents can be manufactured according to known methods. Examples of methods for manufacturing liquid detergents include adding a fragrance composition, a surfactant, and optional components to water, which is used as a dispersion medium, and then mixing them. Examples of methods for manufacturing solid detergents include dispersing and dissolving a fragrance composition, surfactant, and optional components in water and then spray-drying them; spraying a fragrance composition onto a group of particles containing a surfactant and optional components; subjecting a fragrance composition, surfactant, and optional components to equipment such as kneading and extrusion, stirring granulation, or rolling granulation, and further crushing as necessary; and forming the granular material obtained by these methods into any desired dosage form.

[0085] [How to use detergent] There are no particular restrictions on how the detergent is used, and it can be used in the same way as general textile detergents. For example, one method is to put the detergent alone or together with bleach or fabric softener in water to make a cleaning solution, put the textile product in this solution and wash it in a washing machine, or to soak the textile product in the cleaning solution for a certain period of time and then wash it in a washing machine. Alternatively, the liquid detergent may be applied to the soiled area of ​​the textile product, left for a suitable amount of time, and then washed in a washing machine. Examples of textile products include clothing, dishcloths, sheets, curtains, and pillowcases. The material of the textile products is not particularly limited and may be any of the following: natural fibers such as cotton, silk, and wool, or synthetic fibers such as polyester and polyamide.

[0089] TIFF0007844104000006.tif135149

[0090] [Evaluation of residual fragrance in treated textile products] The residual fragrance of textile products treated with liquid fabric softener was evaluated. Ten new, commercially available cotton towels (each weighing approximately 70g) were subjected to a washing process using a commercially available synthetic detergent (product name: Top Super NANOX, manufactured by Lion Corporation). The process consisted of two 10-minute washes followed by two 3-minute rinses (using a 20x dilution ratio). During the second rinse, 1g of liquid fabric softener was added for softening. The fragrance of towels was evaluated according to the following criteria after being dehydrated (1 minute) following a softening treatment and then left at room temperature (24 hours). To prevent the evaluation results from being affected by the rupture of encapsulated fragrances in the liquid fabric softener composition and the leakage of fragrance (core material), the fragrance was evaluated without touching the towels. The evaluation was conducted by 10 expert panelists. The average score of the 10 panelists was calculated to zero decimal places. The results are shown in the "Lingering Fragrance" column of Table 1. An average score of 0 or higher was considered a passing grade. <Evaluation Criteria> 2: No scent was detected, and the characteristics of the scent could not be identified. 1: A faint scent is noticeable, but its characteristics cannot be identified. 0: The scent can be perceived, but its characteristics cannot be identified. -1: The scent can be perceived, and its characteristics can be captured.

[0091] [Odor evaluation of treated textile products after wear] We evaluated the body odor remaining after wearing textile products treated with liquid fabric softener. A blended T-shirt (60% cotton, 40% polyester) was subjected to washing and softening treatment using a commercially available synthetic detergent (product name: Top Super NANOX, manufactured by Lion Corporation) and liquid fabric softener in a washing machine (model JW-Z23A, manufactured by Haier Corporation) (normal course, water temperature 20°C, water hardness 3°DH, bath ratio 20 times). The amount of detergent added was 10 mL / 30 L of tap water, and the amount of liquid fabric softener added was 10 mL / 1.5 kg of laundry. For the treatment, a new 100% cotton undershirt (manufactured by BVD) was used as a garment to adjust the bath ratio, having been washed 5 times on the automatic course in a fully automatic washing machine (manufactured by Panasonic Corporation, NA-F70SD1) (using tap water at approximately 20°C with a hardness of approximately 3°DH). The blended T-shirt, after being treated with a softening agent, was air-dried indoors at room temperature (23°C) for 5 hours. Next, ten men in their 20s to 40s wore blended T-shirts for 12 hours. The odor (body odor) of blended T-shirts after wear was evaluated by sensory assessment according to the following criteria. For the sensory evaluation, the odor of a blended T-shirt treated in the same manner as described above, except that liquid fabric softener was not used, was used as a control. The evaluation was conducted by 10 expert panelists. The average score of the 10 panelists was calculated to zero decimal places. The results are shown in the "Body Odor Suppression Effect" column of Table 1. An average score of 0 or higher was considered a passing grade. <Evaluation Criteria> 2: No odor is detected 1: The odor is barely noticeable and is suppressed compared to the control group. 0: An odor is noticeable, but it is suppressed compared to the control. -1: Odor was detected, equivalent to the control.

[0092] In the aforementioned evaluation criteria, odor refers to a greasy odor (body odor) that results from compounds secreted from three types of skin glands (eccrine glands, sebaceous glands, and apocrine glands) present on the surface of human skin, which adhere to, accumulate, and remain on textile products. Components that make up this greasy odor include fatty acid components (e.g., hexenoic acid, nonanoic acid, isovaleric acid, butyric acid, (E)-3-methyl-2-hexenoic acid), higher fatty acid components (e.g., myristic acid, pentadecanoic acid, palmitic acid, stearic acid, oleic acid, palmitoleic acid), and aldehyde components (e.g., pentanal, hexanal, heptanal, valeraldehyde). In addition to oily odors, other unpleasant odors that can occur in textile products include sour odors (such as body odor from the armpits, or those derived from sweat and bacteria), but these were not included in the evaluation in this example.

[0093] [Evaluation of the balance of fragrances] The balance of fragrances in textile products treated with liquid fabric softener was evaluated. Ten new, commercially available cotton towels (each weighing approximately 70g) were subjected to a washing process using a commercially available synthetic detergent (product name: Top Super NANOX, manufactured by Lion Corporation). The process consisted of two 10-minute washes followed by two 3-minute rinses (using a 20x dilution ratio). During the second rinse, 1g of liquid fabric softener was added for softening. The fragrance of towels after being dehydrated (1 minute) following the softening treatment was evaluated according to the following evaluation criteria. To ensure that the fragrance (core material) leaking from the encapsulated fragrances in the liquid fabric softener composition did not affect the evaluation results, the fragrance evaluation was conducted without touching the towels. The evaluation was performed by 10 expert panelists. The average score of the 10 panelists was calculated to zero decimal places. The results are shown in the "Fragrance Balance" column of Table 1. An average score of 1 or higher was considered to indicate "improved fragrance balance." <Evaluation Criteria> 2: The fragrance is well-balanced from top to bottom. 1: The fragrance develops in a well-balanced manner from the top notes to the base notes. 0: The top, middle, and base notes are unevenly distributed.

[0094] [Liquid detergent] A liquid detergent having the following composition was prepared. The unit of content of each component is mass % relative to the total mass of the liquid detergent. The liquid detergent was prepared by mixing each component according to its composition and adjusting the pH to 7 with a pH adjuster.
