Description

[Technical Field]

[0001] The present invention relates to a textile product treatment agent composition and a method for producing 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 incorporating microcapsules with silica as the shell structure, which contain fragrances produced by the core-shell method, into liquid detergents and fabric softeners for the rinse cycle improves the lingering scent. Patent Document 6 describes silica shell microcapsules with first and second shell structures containing fragrances produced by a sol-gel reaction, and discloses an example of their incorporation into a commercially available fabric softener. Patent Document 7 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] Patent Document 8 discloses a liquid fabric softener composition containing (A) component, which includes one or more selected from specific tertiary amine compounds and their salts and quaternary compounds, component (B) consisting of microcapsules containing a fragrance that includes 90% by mass or more of a fragrance compound having a logP value of 2.0 to 6.0, component (C) consisting of a fragrance precursor that 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. Patent Document 9 discloses a textile product treatment agent composition containing a silicic acid ester compound and a specific fragrance to improve the lifespan of the fragrance on the fabric. Patent Document 10 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 due to moisture absorption. Patent document 11 describes the use of an amine compound with a structural formula containing alkanoylaminopropyldialkylamine to suppress the volatilization of alcohol-based fragrances from textile products, and Patent document 12 describes a liquid fabric softener composition with excellent fragrance persistence containing an ester-type cationic compound, N-alkanoylaminoalkyl-N-dialkylamine or a salt thereof, and an alcohol-based fragrance residue, and describes a microencapsulated fragrance as an alcohol-based fragrance precursor.

[0007] In recent years, several technologies have been proposed to provide lasting fragrance to textile products. However, adsorption of fragrances added to textile treatment agents to textile products is difficult. When incorporated into textile treatment agents used for bath treatment, such as fabric softeners, hydrophilic fragrance compounds with low logP do not remain on the surface of the textile product but flow away. Furthermore, when fragrances are applied directly to textile products by spraying, high vapor pressure fragrance compounds disappear during drying. Microencapsulation of fragrances has been proposed as a means to improve the effectiveness of the fragrance, but the capsules must be physically destroyed to release the fragrance. Some fragrances are released on the fiber surface, which is effective in releasing the scent in situations involving moisture, such as when sweating, but it is not sufficient and challenges remain. Additionally, the creation of fragrance precursors by silicate esterification or fatty acid esterification of alcohol-based fragrance compounds 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, and it remains a challenge that there are limitations in satisfying a wider range of preferences.

[0008] The present invention provides a textile product treatment agent composition and a method for producing the same, which exhibits a pleasant fragrance when the treated textile product becomes wet with water, for example, due to perspiration during use of the textile product. [Means for solving the problem]

[0009] The inventors of the present invention conducted research to improve the effectiveness of fragrance in situations involving moisture, and discovered that by combining specific capsules, which adhere to fibers in an aqueous medium and then disintegrate upon drying, with amino acids, not only is adsorption to textile products improved, but the fragrance becomes noticeably stronger when the textile products are re-wetted, leading to the present invention.

[0010] In other words, the present invention relates to a textile product treatment agent composition containing the following components (a), (b), (c), and water. (a) Components: Microcapsules having a shell containing an inorganic metal and a core containing a fragrance compound inside the shell. (b) Components: Amino acids (c) Ingredients: Cationic surfactant

[0011] Furthermore, the present invention relates to a method for producing a textile product treatment composition by mixing component (a), component (b), component (c), and water. [Effects of the Invention]

Silica is a substance whose structural unit is silicon dioxide. Hereinafter, microcapsules having a shell containing silica as a constituent and a core containing a fragrance compound inside the shell will also be called silica capsules. The fragrance compound can be incorporated into the silica capsule as a fragrance composition containing multiple fragrance compounds.

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.

[0029] Depending on the acidity or alkalinity of the oil phase components containing the fragrance compounds, any acidic or alkaline pH adjusting agent 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.

[0031] 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.

[0034] 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.

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.

[0037] 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 sol-gel reaction in step 1 and the sol-gel reaction in step 2 may be carried out at different reaction temperatures.

[0039] In step 2 of the present invention, an organic polymer may be further added to the aqueous dispersion obtained in step 1 for the purpose of stabilizing the aqueous dispersion and suppressing aggregation. Here, the organic polymer refers to a compound with a weight-average molecular weight of 5,000 or more. Examples of the aforementioned organic polymers include nonionic polymers, cationic polymers, and anionic polymers.

Note that (meth)acrylate means acrylate or methacrylate. Similarly, (meth)acrylic means acrylic or methacrylic.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] The amount of organic polymer 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.

[0045] 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.

[0046] <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 in the total amount of fragrance compounds having a logP of 2.0 or more and a vapor pressure of 0.01 or more and 8.00 or less at 25°C is 25% by mass or more.

[0047] 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.

[0048] In this invention, the ClogP value is calculated using the EPI Suite (registered trademark; The Estimations Programs Interface for Windows version 4.11), software jointly developed by the U.S. Environmental Protection Agency and Syracuse.

[0049] 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).

[0188] <Examples and Comparative Examples> [Preparation of liquid fiber product treatment agent composition] Liquid textile product treatment agent compositions were prepared by mixing each component to achieve the formulation shown in Tables 4 and 5. Specifically, the composition is as follows. Note that the mass % in the table refers to the mass % of the active ingredient (component (a) is the mass %) of the fragrance composition. In a 300 mL beaker, an amount of deionized water equivalent to 85% by mass of the amount required to produce 200 g of liquid textile product treatment agent composition was added, along with components (g), (k), (l), (n), (o), and (q). 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 component (g) was uniformly dissolved 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.

[0189] The mixed solution, heated to a temperature of 60±2℃, was stirred with the aforementioned stirring blade (300 r / m). Component (c), which had been heated and dissolved at 65℃, was added to this mixture over a period of 3 minutes, and 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. To this, the microcapsule aqueous dispersion containing the components (a), (b), water, an optional (d), and an optional (e) obtained from the synthesis of component (a) described above (Step I) was added (Step II). Then, components (f) and (h) were added sequentially and the mixture was stirred for 5 minutes. Furthermore, ion-exchanged water was added to bring the final mass to 200g, and the mixture was stirred for 5 minutes to obtain the liquid textile product treatment agent composition. In addition, sodium hydroxide or hydrochloric acid (component (l)) was used as appropriate, as needed, to adjust the pH of the liquid textile product treatment agent composition to the values ​​shown in Tables 4 and 5.

[0190] 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 for calibration instead of the pH 1.68 standard solution. 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.

[0191] The visible light transmittance of the obtained liquid fiber product treatment agent composition was measured. Specifically, a glass cell with an optical path length of 10 mm was used as the measurement cell, ion-exchanged water was put into the control cell, and measurement was carried out using an ultraviolet-visible spectrophotometer (UV-2500PC manufactured by Shimadzu Corporation). The visible light transmittance (wavelength 660 nm) of the liquid fiber product treatment agent compositions obtained in the examples and comparative examples was all less than 10%, and they were milky liquid fiber product treatment agent compositions.

The washing conditions for each time were a detergent concentration of 0.0667% by mass, 47 L of tap water, a water temperature of 20 °C, a washing time of 10 minutes, 2 rinses, and a dehydration time of 6 minutes.

[0193] A treatment liquid in which 0.867 g (10 g per 1.5 kg of underwear) of each fiber product treatment agent composition described in Tables 4 and 5 was dispersed in 4 L of tap water was put into an electric bucket N-BK2-A manufactured by Panasonic Corporation, and 1 piece of underwear washed by the above method was put in and stirred for 5 minutes.

After standing for several seconds, the cloth was opened and the fragrance at the intersection of the folds was smelled, and the difference in fragrance intensity between the dry and wet times was evaluated as the practical effect of moisture-induced fragrance. The evaluation was carried out by 5 professional panelists who evaluated the fragrance. The evaluation was conducted according to the following criteria, and the average of the evaluations from the five individuals was used as the evaluation result.

[0195] <Evaluation Criteria> (Criteria for evaluating fragrance intensity) 3: There is a large difference in fragrance intensity. 2: Small difference in fragrance intensity 1: I don't notice any difference in scent intensity. (Evaluation criteria for the expressiveness of fragrance) 3: Feels strong and refreshing 2: Feels light and fresh 1: Doesn't feel fresh at all.
