Description

[Technical field]

[0001] The present invention relates to a textile product treatment composition. [Background technology]

[0002] By using a textile product treatment composition containing capsule particles containing a functional compound, it is possible to provide various functions to textile products. Examples of functional compounds include fragrances, oils, silicones, ultraviolet absorbers, bactericides, antibacterial agents, cooling agents, and warming agents. By encapsulating the functional compounds, the functional compounds can be directly applied to textile products without being diluted with water used during treatment. For example, it is known that capsule particles containing a fragrance as a functional compound are contained in a textile product treatment agent for the purpose of enhancing the fragrance of textile products or for the purpose of imparting fragrance by crushing the capsules by physical stimulation.

Patent Document 2 discloses a detergent composition containing an anionic surfactant, a cationic polymer, and an encapsulated fragrance in which a fragrance is encapsulated in a poly(meth)acrylic acid alkyl ester resin. In addition to capsules, Patent Documents 3 and 4 disclose an aqueous liquid containing emulsion particles obtained by emulsifying and dispersing a mixture of a fragrance composition and an oil having a melting point of 30°C or more at normal pressure in water, and a textile product treatment composition containing a cationic compound. Microcapsules using solid oils are also known. Patent Document 5 discloses an ultraviolet protective cosmetic obtained by emulsifying and cooling a liquid oil containing an ionic surfactant, a hydrophobic amphiphilic substance, and an oil-soluble ultraviolet absorber, a solid oil, and water in a specified procedure.

[0005] However, most of the capsule particles containing functional compounds currently in practical use are encapsulated with synthetic polymer compounds, and in recent years, the problem of microplastic pollution has attracted worldwide attention, so there is a demand for the development of alternative technologies. In that case, it is also desirable to efficiently impart functional compounds to textile products.

[0006] The present invention provides a textile product treatment composition which contains capsule particles containing a functional compound such as a fragrance and can efficiently impart the functional compound to textile products such as clothing. [Means for solving the problem]

[0007] In order to solve the above problems, the present inventors have found that a functional compound can be encapsulated by using wax, and have developed capsule particles encapsulating a functional compound that can be used as an alternative to synthetic polymer capsules. In addition, they have found that by forming an emulsion membrane using a cationic surfactant around the wax shell, when the capsule particles are added to a textile product treatment composition containing a cationic surfactant, the functional compound exhibits high adsorption properties regardless of the type of textile.

[0008] The present invention relates to a textile product treatment composition comprising capsule particles (A) [hereinafter sometimes referred to as capsule particles (A) or (A) component] containing a functional compound (a3) ​​encapsulated in a shell containing a wax (a1) and a cationic surfactant (a2), a cationic surfactant (B) [hereinafter sometimes referred to as (B) component] present separately from the capsule particles (A), and water. Effect of the Invention

[0009] According to the present invention, there is provided a textile product treatment composition that contains capsule particles containing a functional compound such as a fragrance, and can efficiently impart the functional compound to textile products such as clothing. For example, according to the present invention, there is provided a textile product treatment composition that contains functional particles, preferably fragrance particles, that can be adsorbed to clothing by washing and deliver a fragrance with high efficiency. The functional particles of the present invention are excellent in the effect of highly efficiently delivering a functional compound that is difficult to adsorb to clothing alone, and are also excellent in the effect of suppressing the volatilization of a functional compound with a high vapor pressure.

[0011] <Component (A)> The textile product treatment composition of the present invention contains capsule particles (A) containing a functional compound (a3) ​​[hereinafter sometimes referred to as component (a3)] encapsulated in a shell containing a wax (a1) [hereinafter sometimes referred to as component (a1)] and a cationic surfactant (a2) [hereinafter sometimes referred to as component (a2)]. The capsule particles as component (A) are particles that encapsulate the functional compound of component (a3), preferably a fragrance composition, in a shell mainly composed of components (a1) and (a2). Components (a1) to (a3) ​​will be described below.

[0012] <Component (a1)> The wax of the component (a1) of the present invention is a compound that is solid at room temperature, for example at 25°C, and is substantially composed of a hydrocarbon or a skeleton of hydrocarbons and ester bonds (excluding the components (a4-1) to (a4-5) described below), and preferably is a hydrocarbon compound that does not have hydroxyl groups or carboxy groups and is composed only of hydrocarbons, or a compound that is composed only of a skeleton of hydrocarbons and ester bonds. Unlike the component (a4) described below, the component (a1) is a hydrophobic organic compound that does not substantially form an α-gel structure together with water and the cationic surfactant of the component (a2). Since wax may be a mixture of compounds having a molecular weight distribution, it may have a wide temperature range from solid to flowable liquid, but in this invention, a solid refers to one that is in a solid state at room temperature, for example, 25°C.

[0013] Examples of the (a1) component include natural waxes such as mineral waxes, such as ozokerite (melting point: 66°C-78°C) and ceresin (melting point: 60°C-80°C), petroleum waxes, such as microcrystalline wax (melting point: 60°C-90°C) and paraffin (melting point: 40°C-70°C), etc. Examples of synthetic waxes include polyethylene wax (melting point: 94°C-152°C), etc.

[0014] From the viewpoint of the stability of the capsule particles (A) and the rate of fragrance adsorption to the fiber, the melting point of the (a1) component is preferably 60°C or higher, more preferably 65°C or higher, and even more preferably 70°C or higher, and from the viewpoint of production, it is preferably 90°C or lower, more preferably 80°C or lower.

[0015] Capsule particles (A) can be obtained, for example, by mixing components (a1), (a2), (a3), and, if necessary, component (a4) described below at a temperature higher than the melting point of component (a1), and then cooling the mixture containing the functional compound of component (a3) ​​to solidify the wax layer of component (a1), thereby encapsulating the mixture. Note that component (a1) is excluded from component (a4).

[0016] <(a2) component> The component (a2) of the present invention is a cationic surfactant. Examples of the component (a2) include amine-based surfactants and quaternary ammonium salt-based surfactants. The component (a2) may be the same as the cationic surfactant of the component (B) described below.

[0017] The cationic surfactant is preferably a quaternary amine represented by the following general formula (A1). [R 1a -(TR 3a ) m -〕 n N(R 2a ) 3-n (A1) [In the formula, R 1a R is a hydrocarbon group having 15 to 23 carbon atoms. 2a is a hydrocarbon group having 1 to 3 carbon atoms, a phenyl group, a benzyl group, and HO-(C p H 2p O) r -C q H 2q When n=1, two R 2a and R are not both groups selected from the group consisting of a phenyl group and a benzyl group. 3a is an alkylene group having 1 to 6 carbon atoms or -(C p H 2p O) r -, and T represents -COO-, -OCO-, -CONH-, -NHCO- or a phenylene group. m is a number of 0 or 1, and m is preferably 0. n is a number of 1 or 2, and n is preferably 1. p and q are each a number of 2 or 3. r is a number of 0 to 5. 1a , R 2a , HO-(C p H 2p O) r -C q H 2q When a plurality of groups p, q, and r are present, they may be the same or different.

[0018] The quaternary amine compound represented by the general formula (A1) can be obtained by a quaternization reaction using the tertiary amine compound represented by the general formula (A1) and an alkylating agent. Examples of the alkylating agent include dimethyl sulfate, diethyl sulfate, methyl chloride, methyl bromide, methyl iodide, etc., and it is preferable to use one or more selected from methyl chloride, dimethyl sulfate, and diethyl sulfate. That is, the component (a2) can be a quaternary amine compound obtained by quaternizing the tertiary amine compound represented by the general formula (A1) with one or more alkylating agents selected from methyl chloride, dimethyl sulfate, and diethyl sulfate. The component (a2) is more preferably a chloride salt, a methyl sulfate salt, or an ethyl sulfate salt of a quaternary ammonium in which, among the groups bonded to the quaternary nitrogen atom, one is a linear primary alkyl or alkenyl group having 15 to 23 carbon atoms, and the remaining groups are selected from a methyl group, an ethyl group, or a hydroxyethyl group.

[0019] <(a3) component> In constructing the capsule particle (A) of the present invention, the component (a3) ​​which corresponds to the core portion is a functional compound. Examples of the functional compound include a fragrance (herein, "fragrance" refers to a fragrance used in the relevant technical field, which may be a single fragrance or a fragrance composition, and includes aromatic essential oils extracted from natural products), oils, lubricants, ultraviolet absorbers, bactericides, antibacterial agents, cooling agents, and warming agents. In the present invention, the component (a3) ​​is preferably a fragrance. The fragrance as the functional compound may be, for example, a single fragrance (single fragrance compound) or a fragrance composition containing a fragrance compound and other components. The fragrance composition may contain, for example, a diluent. Hereinafter, the single fragrance (fragrance compound) and the fragrance composition will be collectively described as the fragrance composition. In addition, the fragrance composition described collectively may be referred to as the component (a3-1).

[0020] The component (a3-1) of the present invention is a fragrance composition. The fragrance composition contains one or more fragrance compounds. The fragrance compound of the component (a3-1) is preferably a fragrance compound having a Hansen solubility parameter (HSP) value such that the HSP distance from the component (a1) is 2.0 or more (requirement 1). Hansen Solubility Parameters (HSP) use a multidimensional vector to indicate the solubility of a substance. This vector is expressed by a dispersion term, a polar term, and a hydrogen bond term. The dispersion term is the van der Waals force, the polar term is the dipole moment force, and the hydrogen bond term is the force possessed by water, alcohol, etc. The HSP distance is the distance between the vector of the (a1) component and the vector of the (a3-1) component.

[0021] In the present invention, the HSP distance is calculated by the following procedure. First, using HSP analysis software, for example, HSPiP ver. 3.0.33, calculations are performed based on the SMILES formula to obtain the values ​​of the polar term (dD), dispersion term (dP), and hydrogen bond term (dH) of each compound. Then, the HSP distance is calculated based on the following formula.

[0022]

number

[0023] Many waxes of component (a1) contain impurities and are mixtures. It is preferable to use paraffin, a petroleum wax, as component (a1). Therefore, in the present invention, the Hansen solubility parameters (HSP) [dD=16.2, dP=2.3, dH=2.4] of a paraffin having 36 carbon atoms, which is a representative pure n-paraffin, are used as the standard for component (a1) to calculate the HSP distance between the component (a3-1) and the fragrance compound. That is, it is preferable that component (a3-1) of the present invention contains a fragrance compound whose HSP distance calculated using a paraffin having 36 carbon atoms as the standard is 2.0 or more. In the present invention, unless otherwise specified, the HSP distance is the HSP distance calculated using a paraffin having 36 carbon atoms as the standard.

[0024] The HSP distance of requirement 1 is 2.1 or more, preferably 2.5 or more, and more preferably 3.0 or more, from the viewpoint of compatibility with wax.

[0025] Many waxes of component (a1) contain impurities and are mixtures. In the case of a wax that is a mixture, as described above, it is preferable that the wax is mixed with a fragrance compound having an HSP distance of 2.0 or more calculated using paraffin having 36 carbon atoms as a standard, such as benzyl benzoate, and the temperature is lowered from a high temperature state and DSC measurement is performed, and the wax has a recrystallization starting temperature of 65°C to 85°C, preferably 70°C to 80°C.

[0026] The fragrance compound of the component (a3-1) includes a fragrance compound having a logP value of 1.0 or more and 6.0 or less (requirement 2).

[0027] The logP value of requirement 2 is, from the viewpoint of emulsification during capsule production, 1.0 or more, preferably 2.0 or more, more preferably 2.3 or more, even more preferably 2.5 or more, and is 6.0 or less, preferably 5.5 or less, more preferably 5.0 or less.

[0028] In the present invention, the logP value is a coefficient indicating the affinity of an organic compound to water and 1-octanol. The 1-octanol / water partition coefficient P is the ratio of the equilibrium concentrations of a compound in each solvent when a trace amount of a compound is dissolved as a solute in a solvent consisting of two liquid phases, 1-octanol and water, and reaches distribution equilibrium, and is generally expressed in the form of their logarithm logP to the base 10. Nowadays, the value of "calculated logP (sometimes called ClogP)" calculated by a calculation program using fragment values ​​of atomic groups determined by the number of atoms constituting the compound molecule and the type of chemical bond is widely used, and in the present invention, the value of ClogP is used when selecting a compound. In the present invention, the value of ClogP is calculated using the software EPI Suite (registered trademark; The Estimations Programs Interface for Windows version 4.11) jointly developed by the U.S. Environmental Protection Agency and Syracuse, Inc.

[0029] Preferred fragrance compounds are those that satisfy requirement 1. Examples include cyclopentadecanolide (3.08, 6.2) and cyclohexadecanolide (3.08, 6.7). Here, the numbers in parentheses are (HSP distance, ClogP) (same below).

In addition, by containing the perfume particles as the component (a2) and further containing the cationic surfactant of the component (B) in the textile product treatment composition outside the particles, the particle dispersibility in the textile product treatment composition and the adsorption to the textile product are excellent.

[0116] <Production of Liquid Softener Composition> In this example, the liquid fabric softener composition shown in Table 3 was produced as a textile product treatment agent by mixing the components as described below. Specifically, the composition percentages by mass are the percentages by mass of the active components. In a 300 mL beaker, sterilized water with sodium hypochlorite in an amount equivalent to 75% by mass of the amount required to produce a liquid softener composition of 200 g (hereinafter referred to as hypochlorite sterilized water), component (G) and component (H) were added, and the temperature was adjusted to 60±2° C. using a water bath. A mixed liquid was obtained by stirring the mixture using a stirring blade as necessary so that the components (G) and (H) were uniformly dissolved in the water. The stirring blade used was a stirring blade with a diameter of 5 mm, with the long side oriented at 90 degrees relative to the rotation center axis of the stirring rod, with three blades, the long side / short side of the blade = 3 cm / 1.5 cm, and the blades installed at an angle of 45 degrees relative to the rotation surface. The mixture, whose temperature had been adjusted to 60±2°C, was stirred (300 rpm) with the stirring blade. The (B) component, the (C) component, and the dissolved and mixed components were added over a period of 3 minutes, and stirred for 5 minutes after the addition was complete. Next, the mixture was cooled to a temperature of 30±2°C using a 5°C water bath. Further, hypochlorous sterilized water was added to the final amount (288.18 g), and the mixture was stirred for 5 minutes to obtain an emulsified mixture. Component (A) was added to the above emulsified mixture so that the blending amount of fragrance (component (a3)) in the composition was 1 mass % (calculated based on the content of fragrance in component (A)), and component (D) was added so that the blending amount was 0.25 mass %. Thereafter, hypochlorous water was added so that the final weight was 200 g. If necessary, the pH was adjusted with component (E) ("appropriately" in the table means the amount used for this adjustment) while stirring for 1 minute at 300 rpm, thereby obtaining a liquid fabric softener composition containing fragrance particles.

The washing conditions for each wash were: detergent concentration 0.0667% by mass, tap water 47 L, water temperature 20°C, washing for 10 minutes, soaking and rinsing twice, and spin-drying for 6 minutes. After drying, the clothes were cut into pieces weighing about 500 mg each. The materials of the various clothing used are as follows: Cotton knit fabric Polyester (PE) jersey PE faille nylon Urethane

[0118] A 100 mL beaker was charged with 40 g of water and a stirrer, 16.5 μl of the above fabric softener composition was added, 1.5 g of fabric was then added, and the mixture was stirred for 10 minutes, then placed in the spin tub of a twin-tub washing machine and spin-dried for 1 minute. The dehydrated cloth was placed in a glass bottle, 30 mL of acetone was added, and the cloth was subjected to ultrasonic treatment for 40 minutes to extract the fragrance adsorbed to the cloth (fragrance amount 1). In addition, 2 mL of the treatment liquid was taken, 2 mL of acetone was added, and the mixture was subjected to ultrasonic treatment for 40 minutes in the same manner to extract the unadsorbed fragrance (fragrance amount 2). The adsorption rate was calculated by measuring the concentrations of the two extracted fragrances using HPLC (Shimadzu Corporation). The adsorption rate (%) was calculated using the formula [amount of fragrance 1 / (amount of fragrance 1+amount of fragrance 2)]×100.
