Description

Technical Field

[0001] The present invention relates to a composition containing capsules encapsulating a functional agent.

Background Art

[0002] Functional agents such as fragrances, sensory agents, humectants, bactericides, etc. are incorporated into products for various uses. For example, fragrances are used in products such as softeners, laundry detergents, body washes, etc. for the purpose of scenting the product itself and clothing, the body, etc. At that time, it is required to be able to stably hold the fragrance so that the fragrance does not escape in the product. In order to sustain the effects of such functional agents, attempts have been made to encapsulate the functional agents in microcapsules and incorporate them into products.

[0003] In addition, microcapsules having a resin such as melamine as a wall material, which have been conventionally used, may fall under microplastics due to rule revisions based on the increasing social environmental awareness in the future, and there are concerns about the environmental load. On the other hand, since the wall material of silica capsules is an inorganic compound, they do not fall under microplastics, and if they can be incorporated into products, a reduction in environmental load can be expected.

[0004] Patent Document 1 discloses microcapsules having a core composed of one or more organic compounds obtained by a predetermined production method, a first shell that encapsulates the core and contains silica as a constituent component, and a second shell that encapsulates the first shell and contains silica as a constituent component, and having an average particle size of 0.5 μm or more and 50 μm or less.

[0005] Patent Document 2 discloses an aqueous liquid detergent and a cleaning agent containing a surfactant and the usual components of further detergents and cleaning agents, the agent containing at least one kind of capsule, the capsule containing an active ingredient, aluminum silicate and silica in a matrix, and aluminum silicate and silica being present in a ratio of 1:10 to 10:1.

[0006] Patent Document 3 discloses a fragrance carrier system containing a capsule-encapsulated fragrance composition, wherein the fragrance composition contains an emulsion of a fragrance compound in an aqueous medium and is encapsulated in a shell containing a silicon-containing material, and the average diameter size of the shell is less than 30 micrometers, a fragrance carrier system containing a capsule-encapsulated fragrance composition, and a surfactant composition containing the fragrance carrier system.

Means for Solving the Problems

[0009] The present invention relates to a composition containing the following component (A), component (B), and water, wherein component (B) is contained in the composition separately from component (A). Component (A): Silica capsules encapsulating a functional agent Component (B): A compound selected from silicic acid and silicate

Effects of the Invention

[0010] According to the present invention, a composition containing silica capsules encapsulating a functional agent and water, and having excellent storage stability at high temperatures is provided.

Modes for Carrying Out the Invention

[0011] Examples of silica capsules containing the functional agent of component (A) include those having a shell containing silica as a constituent component and a core containing the functional agent inside the shell.

[0012] (shell) Component (A) may have a shell containing silica as a constituent component. The shell of component (A) may have a structure in which part or substantially all of the shell's constituent components are silica. From the viewpoint of high-temperature storage stability, it is preferable that the silica is produced from raw material silica that generates silanol compounds by hydrolysis of alkoxysilanes, etc. From the viewpoint of high-temperature storage stability, it is preferable that the shell of component (A) of the present invention is formed by a sol-gel reaction using alkoxysilane as a precursor. In the present invention, "sol-gel reaction" means a reaction in which alkoxysilane undergoes hydrolysis and polycondensation reactions to form silica, which is a constituent component of the shell, through sol and gel states. Specifically, for example, tetraalkoxysilane is hydrolyzed, the silanol compound generates a siloxane oligomer through dehydration condensation and de-alcoholization condensation reactions, and silica is formed by further dehydration condensation reactions.

[0013] Examples of raw material silica include at least one selected from the group consisting of silicon tetrachloride, tetraalkoxysilane, alkylalkoxysilane, water glass, and metal silicates. Among these, tetraalkoxysilane and alkylalkoxysilane are preferred from the viewpoint of high-temperature storage stability, and tetraalkoxysilane is more preferred.

[0014] Specific examples of tetraalkoxysilanes include tetramethoxysilane, tetraethoxysilane, and tetrapropoxysilane. From the viewpoint of high-temperature storage stability, tetramethoxysilane and tetraethoxysilane are preferred, and tetraethoxysilane is more preferred. Specific examples of alkylalkoxysilanes include methyltrimethoxysilane, methyltriethoxysilane, ethyltrimethoxysilane, ethyltriethoxysilane, phenyltrimethoxysilane, phenyltriethoxysilane, dimethyldimethoxysilane, methylphenyldimethoxysilane, dimethyldiethoxysilane, diphenyldiethoxysilane, methylphenyldiethoxysilane, ethylphenyldimethoxysilane, diethyldiethoxysilane, ethylphenyldiethoxysilane, trimethylmethoxysilane, trimethylethoxysilane, dimethylphenylethoxysilane, triethylmethoxysilane, and triethylethoxysilane. These can be used individually or in combination of two or more types. Their condensed products can also be used.

[0015] Furthermore, the shell of the silica capsule of the present invention may contain inorganic polymers other than silica as constituent components, to the extent that they do not impair the effects of the present invention. In the present invention, an inorganic polymer refers to a polymer containing inorganic elements. Examples of such inorganic polymers include polymers consisting only of inorganic elements, and polymers in which the main chain consists only of inorganic elements and has organic groups as side chains or substituents. From the viewpoint of high-temperature storage stability, the inorganic polymer is preferably a metal oxide containing a metal element or a metalloid element, and more preferably a metal alkoxide [M(OR)] x This polymer is formed using [ ] as a precursor by a reaction similar to the silica sol-gel reaction described above. Here, M is a metal or metalloid element, and R is a hydrocarbon group. Examples of metals or metalloid elements that make up metal alkoxides include titanium, zirconium, aluminum, and zinc.

[0016] The shell may have a first shell and a second shell, and component (A) may have a first shell enclosing a core containing one or more functional agents, and a second shell enclosing the first shell. Furthermore, component (A) of the present invention may have a third shell made of an organic polymer compound in contact with the second shell. Such a multilayer shell can retain functional agents such as fragrances for a long period of time and is preferable from the viewpoint of high-temperature storage stability.

[0017] The thickness of the shell (or the first shell if there is a first and second shell) is preferably 5 nm or more, preferably 20 nm or less, and more preferably 15 nm or less, from the viewpoint of high-temperature storage stability. Furthermore, from the viewpoint of high-temperature storage stability, the shell (or the first shell if there is a first and second shell) is preferably a dense layer with as few pores as possible in order to preserve the encapsulated functional agent for a long period of time.

[0018] (A) If component has a second shell, the thickness of the second shell is preferably 10 nm or more, more preferably 20 nm or more, and preferably 100 nm or less, more preferably 80 nm or less, from the viewpoint of high-temperature storage stability. From the viewpoint of high-temperature storage stability, the second shell is preferably a mesoporous structure in which silica exists not only in the direction along the interface with the first shell but also in the thickness direction. Here, the "mesoporous structure" in the second shell refers to a structure in which the diameter of the pores (so-called mesopores) present in the structure is preferably greater than 2 nm, more preferably 10 nm or more, even more preferably 30 nm or more, and preferably 50 nm or less, more preferably 45 nm or less, and even more preferably 40 nm or less, from the viewpoint of high-temperature storage stability. Due to the mesoporous structure of the second shell, component (A) possesses high mechanical strength.

[0019] The average thickness of the first and second shells of component (A), as well as the pore diameters of the first and second shells, can be measured by transmission electron microscopy (TEM). Specifically, the thickness of the first and second shells and the pore diameters of the first and second shells are measured on photographs under transmission electron microscopy. This operation is performed by changing the field of view five times. From the obtained data, the distribution of the thickness and pore diameter of the first and second shells is determined. The approximate magnification of the transmission electron microscope is 10,000 to 100,000 times, but it is adjusted appropriately depending on the size of component (A). Here, for example, the product name "JEM-2100" (manufactured by JEOL Ltd.) can be used as the transmission electron microscope (TEM).

[0020] (core) The core of component (A) of the present invention comprises one or more functional agents. The functional agent may be, for example, an oil-soluble liquid. When a fragrance is used as the functional agent, component (A) encapsulates the fragrance inside the shell, and when the shell breaks, the fragrance is released and emits a scent.

[0025] The ClogP value of the functional agent is preferably 2 or higher, more preferably 3 or higher, even more preferably 4 or higher, and preferably 30 or lower, more preferably 20 or lower, and even more preferably 10 or lower. A ClogP value of 2 or higher for the functional agent improves the encapsulation rate (hereinafter also referred to as "encapsulation rate") of the functional agent within component (A). The same applies when the functional agent is a fragrance composition containing multiple fragrances; a ClogP value of 2 or higher for the fragrance composition improves the encapsulation rate (encapsulation rate) of the fragrance composition within component (A). Here, the ClogP value is the "calculated logP(ClogP)" calculated using the method described in A. Leo in "Comprehensive Medicinal Chemistry", Vol.4, (C. Hansch, PG Sammes, JB Taylor and CARamsden, Eds.), p.295, Pergamon Press, 1990, and is the ClogP value calculated using the program CLOGP v4.01. In the case of a fragrance composition containing multiple fragrances, the CLogP value of the fragrance composition can be obtained by multiplying the CLogP value of each fragrance by its volume ratio in the fragrance composition and summing them up.

[0026] Furthermore, from the viewpoint of retaining the functional agent, the oil-water interface tension of the functional agent is preferably 7 mN / m or more, more preferably 10 mN / m or more, and even more preferably 13 mN / m or more at 25°C. The oil-water interface tension of the functional agent can be measured, for example, using a contact angle meter "DropMaster DM-501" (product name, manufactured by Kyowa Interface Science Co., Ltd.).

[0027] (A) The volume-average particle size of component (A) is preferably 0.5 μm or more, more preferably 0.7 μm or more, even more preferably 1 μm or more, and preferably 50 μm or less, more preferably 10 μm or less, and even more preferably 5 μm or less, from the viewpoint of compatibility with the product and retention of the functional agent. In this invention, the volume-average particle size of component (A) can be measured by the method described in the examples. For example, it can be measured using the laser diffraction / scattering particle size distribution analyzer "LA-960" (product name, manufactured by Horiba, Ltd.). In this case, a flow cell is used for measurement, the medium is water, and the refractive index is set to 1.40-0i. A dispersion containing component (A) is added to the flow cell, and the measurement is performed at a concentration where the transmittance is around 90%, and the average particle size is determined on a volume basis.

[0028] If component (A) is a component having a first shell and a second shell containing silica as a constituent component, and a core containing one or more functional agents inside the first shell, then component (A) can be obtained, for example, by a manufacturing method having the following steps (1) and (2). Step (1): A step in which an organic phase containing one or more functional agents and raw material silica (e.g., tetraalkoxysilane) is mixed with an aqueous phase containing a surfactant (e.g., a cationic surfactant) and emulsified, and then a sol-gel reaction is carried out under acidic conditions to form a shell and create a capsule containing the functional agent. Step (2): A step in which raw material silica (e.g., tetraalkoxysilane) is added to the dispersion containing the capsules obtained in step (1) to carry out a sol-gel reaction and form a capsule having a second shell that encloses the first shell. More specifically, component (A) can be obtained, for example, by a manufacturing method comprising the following steps (1a) and (2a), and optionally further comprising the following step (3a). Step (1a): A step in which an organic phase containing one or more functional agents and tetraalkoxysilane, wherein the amount of tetraalkoxysilane is 10% by mass or more and 60% by mass or less relative to the functional agent is emulsified in an aqueous phase containing a surfactant (e.g., a cationic surfactant), a sol-gel reaction is carried out under acidic conditions to form a capsule having a core and a first shell. Step (2a): A step in which a tetraalkoxysilane is added to an aqueous dispersion containing the capsule obtained in step (1a), and the initial pH of the sol-gel reaction in step (2a) is maintained lower than the initial pH of the sol-gel reaction in step (1a), and the sol-gel reaction is carried out to form a capsule having a second shell enclosing a first shell. Step (3a): A step of mixing the dispersion containing the capsule obtained in step (2a) with an aqueous solution of an organic polymer compound (e.g., an anionic synthetic polymer compound) to form a capsule having a third shell.

[0029] Here, the "sol-gel reaction" in steps (1) and (2), as well as steps (1a) and (2a), is a reaction in which raw material silica (silica precursor) is polymerized while removing alcohol by hydrolysis and polycondensation under acidic conditions to synthesize the first and second shells of silica.

[0154] <Examples and Comparative Examples> Using the following ingredients, compositions shown in Tables 2 to 6 were prepared, and the storage stability and other properties of the obtained compositions were evaluated using the following method.

[0155] <Composition ingredients> [Component (A)] A-1: Fragrance-encapsulated silica capsules obtained by Method 1 below [Method 1] Process (1) 3.0 g of Cotamin 60W (product name, manufactured by Kao Corporation, cetyltrimethylammonium chloride, 30% by mass of active ingredient) was diluted with 750 g of deionized water to obtain the aqueous phase component. To this aqueous phase component, an oil phase component prepared by mixing 200 g of model fragrance A1 in the proportions shown in Table 1 and 50 g of tetraethoxysilane (hereinafter also referred to as "TEOS") was added. The mixture was emulsified using a homomixer (manufactured by HsiangTai, model: HM-310, the same applies hereafter) at a rotation speed of 8,500 rpm to obtain the emulsion. The volume-average particle size of the emulsion droplets at this time was 1.4 μm. The pH of the resulting emulsion was adjusted to 3.8 using a 1% aqueous sulfuric acid solution. The mixture was then transferred to a separable flask equipped with a stirring blade and a condenser, and stirred at 200 rpm for 24 hours while maintaining the liquid temperature at 30°C to obtain an aqueous dispersion containing silica capsules having a core made of model fragrance A1 and a first shell made of silica.

[0156] Process (2) While stirring the aqueous dispersion obtained in step 1 at a liquid temperature of 30°C, 21 g of TEOS was added dropwise over 420 minutes. After addition, stirring was continued for a further 17 hours, followed by cooling to form a second shell enclosing the first shell, resulting in an aqueous dispersion containing silica capsules in which model fragrance A1 was encapsulated in amorphous silica (the content of model fragrance A1 (functional agent) was 19.4% by mass in the silica capsules). The volume-average particle size of the silica capsules was 2.1 μm. The volume-average particle size of the emulsion droplets and silica capsules (I) was measured using a laser diffraction / scattering particle size distribution analyzer "LA-960" (product name, manufactured by Horiba, Ltd.). A flow cell was used for the measurement, the medium was water, and the refractive index was set to 1.40-0i. The aqueous dispersion containing the emulsion or silica capsules was added to the flow cell, and measurements were performed at a concentration where the transmittance was around 90%, and the volume-average particle size was determined on a volume basis (the same method was used to measure the volume-average particle size of the other (A) components). The thickness of the first shell was approximately 5 nm, and the thickness of the second shell was 5-30 nm.

[0157] Model fragrance A1 was a fragrance with the composition shown in Table 1 below (volume-average ClogP: 3.9, specific gravity: 0.96). The volume-average ClogP value of model fragrance A1 was calculated by adding the volume fraction of each fragrance component contained in model fragrance A1 to its respective ClogP value. In this calculation, all fragrance components with a content of 0.5% by mass or more in model fragrance A1 were considered, and fragrance components with a content of less than 0.5% by mass in model fragrance A1 were also included in the calculation if their specific gravity and ClogP value were known.

To this aqueous solution, an oil phase prepared by mixing 120 g of model fragrance A2 and 30 g of tetraethoxysilane (TEOS) was added, and the mixture was emulsified using a homomixer set to a rotation speed of 8500 rpm. After adjusting the pH to 3.7 with 1 wt% sulfuric acid, the mixture was transferred to a separable flask equipped with a stirring blade and a condenser, and stirred at 160 rpm for 17 hours while maintaining the liquid temperature at 30°C to obtain a suspension containing silica capsules with a volume average particle size of 1.9 μm encapsulated in amorphous silica (the content of model fragrance A2 (functional agent) was 20% by mass in the silica capsules). The composition of Model Fragrance A2 was 25% by mass of limonene, 25% by mass of methyl-iso-eugenol, and 50% by mass of α-hexylcinnamaldehyde.

[0160] A-3: Silica capsules containing a cooling agent obtained by method 3 below. [Method 3] Process (1) An aqueous solution was prepared by diluting 0.90 g of the product name "Cotamin 60W" (manufactured by Kao Corporation; cetyltrimethylammonium chloride, 30% by mass of active ingredient) with 224.10 g of deionized water. To this aqueous solution, an oil phase prepared by mixing 60 g of a cooling agent and 15 g of tetraethoxysilane (TEOS) was added, and the mixture was emulsified using a homomixer set to a rotation speed of 8500 rpm. After adjusting the pH to 3.7 with 1 wt% sulfuric acid, the mixture was transferred to a separable flask equipped with a stirring blade and a condenser, and stirred at 160 rpm for 24 hours while maintaining the liquid temperature at 30°C. Process (2) Next, maintaining the liquid temperature at 30°C and with a suspension pH of 3.7, 9.0 g of TEOS was added dropwise over 420 minutes. After addition, stirring was continued for another 24 hours, followed by cooling to obtain a suspension containing silica capsules with a volume-average particle size of 1.4 μm encapsulated in amorphous silica (containing 20% ​​by mass of the cooling agent (functional agent) in the silica capsules). The composition of the cooling agent was 60% by mass of L-menthol, 10% by mass of isopropyl myristate, and 30% by mass of hexyl salicylate.
