Description

[Technical Field]

[0001] The present invention relates to a sheet-type cosmetic in which a liquid composition is impregnated into a sheet. [Background technology]

[0002] Sheet-type cosmetics consist of a sheet impregnated with a liquid composition containing cosmetic ingredients and are used to wipe away sweat, sebum, and other substances from the skin. In recent years, there has been a growing demand for sheet-type cosmetics that can be used on a wider area, such as the chest and back, in addition to areas like the neck and arms, creating a need to increase the amount of liquid composition impregnated into the sheet.

[0003] Sheet-type cosmetics are required to provide a refreshing feeling that lasts after use (after wiping), meaning that the refreshing feeling experienced immediately after use should persist for a long time, even after sweating begins. To achieve this sustained refreshing feeling after use, porous silica that absorbs sweat and sebum can be incorporated into the liquid composition (see, for example, Patent Documents 1 and 2).

[0008] Sheet-type cosmetic products are manufactured and provided as a package in which a liquid composition is impregnated into a sheet and then sealed with packaging material. The sheets inside the package may be folded. In addition, in packaged sheet-type cosmetic products, if multiple sheets of cosmetic products are stacked and contained within the packaging material, the sheets of cosmetic products are taken out and used one at a time.

[0009] When a liquid composition contains silica particles, the silica particles may settle due to gravity, resulting in variations in the amount of silica particles between, for example, one side of a sheet and the other, or between one side and the other. When a sheet is folded and contained in packaging material, there may be a difference in the amount of silica particles between the top and bottom surfaces. Furthermore, in products containing multiple sheet-like cosmetic materials, there may be variations in the amount of silica particles between each sheet.

[0010] This invention relates to a technique for maintaining a state in which silica particles are well dispersed and retained in a sheet-like cosmetic composition impregnated with a liquid composition.

[0011] The embodiments of the present invention will be described below. The present invention is not limited to the embodiments shown below, and various modifications can be made without departing from the spirit of the invention.

[0012] [Overall composition of sheet-type cosmetic product] ·Schematic configuration The sheet-like cosmetic composition according to this embodiment comprises a sheet X and a liquid composition Y impregnated in the sheet X, and is a sheet product used to wipe away sweat, sebum, and other substances adhering to the skin. The sheet X is composed of one or more sheets selected from woven fabrics and nonwoven fabrics, and is configured as a base material that holds each component of the liquid composition Y. The liquid composition Y contains component (A), component (B), and water. Preferably, the liquid composition Y further contains component (C). In this embodiment, "liquid" in the liquid composition Y refers to being liquid at 25°C, for example, having a viscosity of 20,000 mPa·s or less at 25°C. In this embodiment, the state in which the sheet X is impregnated with the liquid composition Y broadly includes not only the state after the sheet X has been immersed in the liquid composition Y, but also the state in which the liquid composition Y has been impregnated into the sheet X using a spray or nozzle (dropper, etc.), and so on, in which case the liquid composition Y is held over a wide area of ​​the sheet X.

[0013] • Ingredient (A) Component (A) of liquid composition Y is composed of silica particles. The silica particles constituting component (A) constitute the powder component of liquid composition Y and have the effect of adsorbing sweat, sebum, etc. In liquid composition Y, it is preferable to use porous silica with a large surface area as component (A) in order to adsorb more sweat, sebum, etc. Furthermore, it is preferable that the silica particles constituting component (A) are untreated from the viewpoint of uniform dispersion in liquid composition Y.

[0014] The particle size of the silica particles constituting component (A) is advantageous to be small in order to obtain a smooth feel on the transferred skin, and not too small in order to be easily retained by the fibers of sheet X. From these perspectives, component (A )teeth It is preferable that the component (A) contains silica particles with a particle size of 0.2 μm to 25 μm. In particular, the silica particles constituting component (A) are preferably those with an average particle size of 0.5 μm to 20 μm, more preferably those with an average particle size of 1.0 μm to 15 μm, and most preferably those with an average particle size of 3.0 μm to 12 μm. It is also preferable that component (A) contains silica particles with a particle size of 3.0 μm to 20 μm. Furthermore, it is also preferable that component (A) contains silica particles with a particle size of 8.0 μm to 20 μm. In this embodiment, particle size is the particle size measured using a Coulter Counter Multisizer (manufactured by Beckman Coulter) in accordance with JIS Z 8832:2010, and average particle size is the volume-based median diameter (D50) obtained by measurement.

[0015] From the viewpoint of maintaining a good dispersed state of the silica particles, it is advantageous that the oil absorption of the silica particles constituting component (A) is high. From this viewpoint, the oil absorption of the silica particles constituting component (A) is preferably 10 mL / 100 g or more, more preferably 20 mL / 100 g or more, and still more preferably 30 mL / 100 g or more. In addition, it is advantageous that the oil absorption of the silica particles constituting component (A) is not excessively high, so as to obtain a smooth and pleasant feel on the skin to which liquid composition Y is transferred. From this viewpoint, the oil absorption of the silica particles constituting component (A) is preferably 450 mL / 100 g or less, more preferably 400 mL / 100 g or less, and still more preferably 300 mL / 100 g or less. In the present embodiment, the oil absorption of silica particles can be measured by a method in accordance with JIS K 5101-13-2.

[0016] In liquid composition Y, it is advantageous that the content of silica particles is high in order to more effectively obtain the above-described effects, and it is advantageous that the content of silica particles is not excessively high in order to obtain better skin compatibility. From these viewpoints, the content of component (A) in liquid composition Y is preferably 0.5 mass% or more and 20 mass% or less, more preferably 1 mass% or more and 12 mass% or less, and still more preferably 2 mass% or more and 8 mass% or less.

[0017] • Component (B) Component (B) of liquid composition Y is constituted by polyether-modified silicone. The polyether-modified silicone constituting component (B) is a nonionic surfactant having relatively high hydrophobicity. In liquid composition Y, the HLB (Hydrophile Lipophile Balance) value of component (B) is 10 or less, preferably less than 8.0, more preferably less than 7.0, and still more preferably less than 5.0. In addition, the HLB value of component (B) is preferably 1.0 or more, more preferably 2.0 or more, and still more preferably 4.0 or more. The HLB value is an index representing the balance between hydrophilicity and lipophilicity, and in the present invention, it refers to a value determined by the following Griffin's formula. HLB value = 20 × Sum of molecular weights of hydrophilic groups / Molecular weight

[0018] In liquid composition Y, it is considered that the polyether-modified silicone coats each silica particle, thereby imparting hydrophobicity to the surface of the silica particles. As a result, in liquid composition Y, hydrophobic interaction comes to act between silica particles, and a plurality of silica particles are bound by a weak force due to the hydrophobic effect, so that they can exist as secondary particles with a large diameter. Since these silica secondary particles have hydrophobicity, they are less likely to be decomposed by the presence of water in liquid composition Y. In liquid composition Y, the lower the HLB value of the polyether-modified silicone is, the more hydrophobic the surface of the silica particles coated with the polyether-modified silicone becomes. Therefore, the silica particles are prone to aggregate due to hydrophobic interaction to form secondary particles.

[0019] For this reason, in the sheet-shaped cosmetic according to the present embodiment, as shown in Figure 1, silica secondary particles that cannot pass through the gaps between fibers constituting sheet X can be stably retained by the fibers constituting sheet X. As a result, in the sheet-shaped cosmetic according to the present embodiment, even when the amount of liquid composition Y impregnated into sheet X is increased, the uniform dispersion state of silica particles in sheet X is easily maintained over a long period of time.

[0020] Furthermore, in the sheet-shaped cosmetic according to the present embodiment, since the silica particles exist as large-diameter secondary particles in liquid composition Y, even if a woven fabric and / or non-woven fabric with relatively coarse fiber openings is used as sheet X, the uniform dispersion state of silica particles in sheet X can be maintained. Therefore, for the sheet-shaped cosmetic according to the present embodiment, the options for woven fabrics and / or non-woven fabrics used as sheet X are expanded.

[0021] In the sheet-type cosmetic composition according to this embodiment, a uniform dispersion state of silica particles is maintained within the sheet X, so that silica particles are present throughout the entire surface of the sheet X. Therefore, a predetermined amount of silica particles is transferred to the skin regardless of which part of the sheet X is used during wiping. For this reason, the sheet-type cosmetic composition according to this embodiment can more reliably obtain the effect of adsorbing sweat, sebum, and other substances by silica particles.

[0022] Furthermore, in the sheet-type cosmetic composition according to this embodiment, silica particles that exist as secondary particles due to weak bonds within the sheet X are decomposed into primary particles when the liquid composition Y is transferred to the skin. As a result, the adsorption effect of sweat and sebum by the silica particles is obtained more uniformly on the skin to which the liquid composition Y has been transferred, resulting in a smooth and pleasant texture.

[0023] Furthermore, in liquid composition Y, the polyether-modified silicone imparts a soft touch to the surface of the silica particles, in addition to its hydrophobic properties. Therefore, when liquid composition Y is applied to the skin, the inherent hard texture of the silica particles is not directly felt, thus alleviating the discomfort caused by the presence of silica particles.

[0024] In liquid composition Y, a larger amount of polyether-modified silicone is advantageous to more effectively obtain the effects described above, while a smaller amount of polyether-modified silicone is advantageous to obtain a more comfortable user experience. From these viewpoints, the content of component (B) in liquid composition Y is preferably 0.02% by mass or more and 2.0% by mass or less, more preferably 0.03% by mass or more and 1.0% by mass or less, and even more preferably 0.05% by mass or more and 0.5% by mass or less.

[0025] Furthermore, in liquid composition Y, it is preferable that the amount of component (B) is not too much compared to component (A) in order to more effectively obtain the above-mentioned effects of component (B) and to effectively obtain a smooth feeling on the skin. Therefore, it is preferable to blend component (A) and component (B) in a well-balanced manner. Specifically, in liquid composition Y, the ratio of the mass of component (A) to the mass of component (B) rate A certain mass ratio (A) / (B) is preferably 0.5 to 180, more preferably 1.0 to 150, even more preferably 2.0 to 100, and most preferably 4.0 to 80. It is also preferable that the mass ratio (A) / (B) is 4.0 to 150. Furthermore, it is also preferable that the mass ratio (A) / (B) is 2.0 to 80.

[0026] ·Component (C) The anionic polymer constituting component (C) can suppress the sedimentation of silica particles, which exist as heavier secondary particles due to the thickening effect caused by electrostatic repulsion, when the liquid composition Y exists alone before being impregnated into the sheet X during the manufacturing process. As a result, when the liquid composition Y is impregnated into the sheet X, the silica particles can be dispersed more uniformly, making it easier to obtain a sheet-type cosmetic with well dispersed silica particles. Furthermore, component (C) also has the effect of suppressing the sedimentation of silica particles in the liquid composition Y after it has been impregnated into the sheet X.

[0027] In liquid composition Y, a larger amount of anionic polymer is advantageous to more effectively obtain the effects described above, while a smaller amount of anionic polymer is advantageous to obtain a more comfortable user experience. From these viewpoints, the content of component (C) in liquid composition Y is preferably 0.005% by mass or more and 0.3% by mass or less, more preferably 0.01% by mass or more and 0.1% by mass or less, and even more preferably 0.02% by mass or more and 0.06% by mass or less.

[0028] Furthermore, in liquid composition Y, it is preferable to blend component (A) and component (C) in a balanced manner so that the above-mentioned effects of component (C) can be more effectively obtained. Specifically, in liquid composition Y containing component (C), the mass ratio (A) / (C), which is the ratio of the mass of component (A) to the mass of component (C), is preferably 2 to 2000, more preferably 10 to 1200, even more preferably 10 to 750, even more preferably 15 to 300, even more preferably 34 to 300, even more preferably 80 to 300, and most preferably 80 to 100. It is also preferable that the mass ratio (A) / (C) is 50 to 500.

[0029] Furthermore, in liquid composition Y, it is advantageous that the amount of component (C) is not too much relative to component (B) in order to more effectively obtain the hydrophobic effect of component (B). Specifically, in liquid composition Y containing component (C), the mass ratio (C) / (B), which is the ratio of the mass of component (C) to the mass of component (B), is preferably 15 or less, more preferably 10 or less, even more preferably 2 or less, and even more preferably 0.6 or less.

[0030] ·water In liquid composition Y, for example, purified water, ion-exchanged water, or distilled water can be used as water. In liquid composition Y, the remainder after removing components other than water can be water. In liquid composition Y, a large amount of water is advantageous for suppressing skin irritation, while a moderate amount of water is advantageous from the viewpoint of quick drying of the skin after wiping. From these viewpoints, the water content in liquid composition Y is preferably 45% by mass or more and 98% by mass or less, more preferably 55% by mass or more and 75% by mass or less, and even more preferably 60% by mass or more and 75% by mass or less.

[0031] Other ingredients Liquid composition Y may contain components other than those listed above, as needed. For example, liquid composition Y may further contain component (D), which is composed of a cationic compound. Among cationic compounds, cationic polymers tend to cause "slippery" or "sticky" sensations on skin to which liquid composition Y is transferred. Furthermore, cationic compounds tend to counteract the thickening effect due to electrostatic repulsion by anionic polymers when liquid composition Y exists alone before being impregnated into sheet X. For this reason, it is preferable that liquid composition Y does not contain component (D), but if it contains component (C) and component (D), the mass ratio (D) / (C), which is the ratio of the mass of component (D) to the mass of component (C), is preferably less than 0.1, more preferably less than 0.01, and even more preferably less than 0.005.

[0032] Furthermore, liquid composition Y may also contain component (E), which is composed of a nonionic surfactant other than component (B). This makes it possible to include oils such as silicone oil, ester oil, and hydrocarbon oil, for example, and further improve the skin compatibility of liquid composition Y. If no oils are included, the content of component (E) in liquid composition Y is preferably 1.5% by mass or less, more preferably 1% by mass or less, and even more preferably 0.5% by mass or less. In addition, the HLB value of the nonionic surfactant constituting component (E) is preferably 1.0 to 15, more preferably 2.0 to 12.1, from the viewpoint of improving the feel of the sheet-type cosmetic during and after use.

[0033] Furthermore, liquid composition Y may contain ethanol to obtain oil removal, quick drying, and preservative effects. Liquid composition Y may also contain an oiling agent. Preferably, the oiling agent to be included in liquid composition Y is a silicone oil, an ester oil, or a hydrocarbon oil, more preferably a silicone oil or an ester oil, and even more preferably a silicone oil.

[0034] In addition, liquid composition Y may contain other components besides those listed above. Specifically, liquid composition Y may contain, for example, preservatives, pH adjusters, humectants, anti-inflammatory agents, whitening agents, UV absorbers, bactericides, antiperspirants, cooling agents, chelating agents, fragrances, colorants, and the like, in addition to the components listed above.

[0035] [Packaging] The packaging body containing the sheet-like cosmetic material according to this embodiment will now be described. As shown in Figure 2, the packaging body 100 has a plurality of sheet-like cosmetic materials 10 and a packaging material 20. In the packaging body 100, the sheet-like cosmetic materials 10 according to this embodiment are housed in the packaging material 20 in a laminated state where they are directly stacked on top of each other. In Figure 2, a portion of the packaging material 20 is cut out to show the laminated state of the plurality of sheet-like cosmetic materials 10.

[0036] The packaging material 20 has an opening 20a at a position opposite to the lamination direction of the sheet-like cosmetic. The packaging material 20 has a sealing body S attached to it that covers the opening 20a. In the package 100, it is possible to remove the sheet-like cosmetic 10 one by one by peeling off at least a part of the sealing body S from the packaging material 20 to open the opening 20a.

[0037] In the packaging 100, even when stored for a long period of time, the silica particles present as secondary particles in each sheet-like cosmetic 10 remain attached to the fibers constituting the sheet X. Therefore, in the packaging 100, the silica particles effectively adsorb sweat and sebum regardless of the position of the sheet-like cosmetic 10 in the stacking direction. In other words, variations in the feel of the sheet-like cosmetic 10 can be suppressed within a single packaging 100, and the quality can be maintained at a good level.

[0038] In particular, the packaging 100 is often stored with the opening of the packaging material 20 facing vertically upward. Even when the packaging 100 is stored in this state for a long period of time, the silica particles in the laminate of sheet-like cosmetic material 10 do not settle by weaving between the fibers that make up each sheet X, and the silica particle content in the upper sheet-like cosmetic material 10 is prevented from decreasing.

[0039] In this embodiment, the packaging 100 does not necessarily have to be configured in which multiple sheet-like cosmetic materials 10 are contained in the packaging material 20; in other words, it may have a configuration in which only a single sheet-like cosmetic material 10 is contained. Even with this configuration of packaging 100, if a single sheet-like cosmetic material 10 is contained in the packaging material 20 in a folded and laminated state, the effect of preventing uneven distribution of silica particles in the laminated direction can be effectively obtained in the same way as described above.

[0041] The fibers constituting sheet X preferably include at least one of cotton, rayon, pulp, PE, PP, PET, and nylon, from the viewpoint of balancing the liquid retention properties of liquid composition Y and the transferability of liquid composition Y to the skin.

In a laminated sheet X, the types of woven and / or nonwoven fabrics constituting each layer may be different, and each layer may be joined by embossing, heat sealing, or the like.

In this embodiment, the average basis weight is determined in accordance with JIS L 1913, by cutting sheet X to a certain area and measuring its mass, and using this as the basis weight per 1 m². 2 It is calculated by converting it to its mass.

[0043] The thickness of sheet X is preferably 0.15 mm to 1.30 mm, and more preferably 0.30 mm to 0.90 mm, from the viewpoint of good retention of the liquid composition Y and a good feel during wiping.

[0054] In Examples 1-20 and Comparative Examples 1-3, the impregnation rate, which is the ratio of the mass of the liquid composition impregnated into the sheet to the mass of the sheet, was set to 400%. Furthermore, the liquid compositions used in Examples 1-20 and Comparative Examples 1-3 all contained 25% by mass of ethanol (95% concentration). First, the evaluation method common to Examples 1-20 and Comparative Examples 1-3 will be explained.

[0055] • Evaluation of silica particle sedimentation (after impregnation) In evaluating the silica particle sedimentation properties (after impregnation), the likelihood of silica particles settling in a sheet impregnated with the liquid composition was assessed. The specific evaluation method was as follows: First, the liquid composition was impregnated into the sheet by spraying or using a dropper. The ends of the sheet impregnated with the liquid composition were held, and the sheet was bent so that the center was indented downwards. In this state, it was sealed in an aluminum pillow and kept for two weeks. After keeping it, the center of the sheet was pressed onto black drawing paper to transfer the liquid composition. The more widely dispersed the silica particles transferred onto the black drawing paper were, rather than being locally unevenly distributed, the less likely it was that silica particles would settle. The silica particle sedimentation properties (after impregnation) were evaluated on a five-point scale: "Silica particles are locally unevenly distributed: 1", "Silica particles are locally unevenly distributed to some extent: 3", "Silica particles are not locally unevenly distributed: 5", "Intermediate between 1 and 3: 2", and "Intermediate between 3 and 5: 4". Figures 3-5 show photographs of black drawing paper onto which a liquid composition has been transferred. In the photograph shown in Figure 3, the evaluation is "1", in the photograph shown in Figure 4, the evaluation is "3", and in the photograph shown in Figure 5, the evaluation is "5". A rating of "1" indicates that when a 20-sheet laminate is stored at room temperature for one month with the widest surface facing downwards, the bottom sheet has a clearly different feel, and a rating of "3" indicates that this is an acceptable condition.

[0056] • Evaluation of silica particle sedimentation (before impregnation) In evaluating the silica particle sedimentation properties (before impregnation), the likelihood of silica particles settling in the liquid composition when it exists alone before impregnation into the sheet was assessed. The specific evaluation method was as follows: After the impregnation liquid was mixed and allowed to stand for one month, it was thoroughly redispersed, and the time it took for it to separate into two layers was visually confirmed. The silica particle sedimentation properties (before impregnation) were evaluated on a five-point scale: "Sedimentation in less than 30 minutes: 1", "Sedimentation in 30 minutes to less than 1 hour: 2", "Sedimentation in 1 hour to less than 3 hours: 3", "Sedimentation in 3 hours to less than 5 hours: 4", and "No sedimentation in 5 hours or more: 5".

[0057] • Evaluation of the smoothness and powderiness of the skin after wiping. Samples of the prepared liquid composition were evaluated for smoothness and powdery feel to the touch after wiping. The specific evaluation method is as follows. The skin was wiped with a sheet-shaped cosmetic, and evaluated by the tester's tactile sensation. Smoothness of the touch was evaluated on a 5-level scale: "Not smooth: 1", "Cannot say either way: 2", "Slightly smooth: 3", "Smooth: 4", "Very smooth: 5". Powdery feel of the touch was evaluated on a 5-level scale: "Powdery: 1", "Cannot say either way: 2", "Slightly not powdery: 3", "Not powdery: 4", "Not powdery at all: 5".

[0058] • Examples 1 to 6 In Examples 1 to 6, nonwoven fabrics having the configuration shown in Table 1 and the annotations thereto were used as the sheet, respectively. In Table 1, the numerical value described for the sheet is the average basis weight of the sheet (g / m 2 ). In Examples 2 to 6, sheets having different configurations from each other were used. In Example 1, the same sheet as that used in Example 2 was used.

[0059] In Examples 1 to 6, liquid compositions composed of the components shown in Table 1 were used, respectively. The liquid compositions used in Examples 2 to 6 have a common configuration containing an anionic polymer (component (C)). On the other hand, the liquid composition used in Example 1 does not contain component (C). It should be noted that, not limited to Examples 2 to 6, 48% caustic potash (48% by mass potassium hydroxide aqueous solution) was added as a pH adjuster to liquid compositions containing component (C).

[0060] Table 1 shows the mass ratio (A) / (B), mass ratio (A) / (C), and mass ratio (C) / (B) for the liquid compositions used in Examples 1 to 6. All of the liquid compositions used in Examples 1 to 6 had the mass ratio (A) / (B) within the range of the above embodiment. In addition, all of the liquid compositions containing component (C) used in Examples 2 to 6 had the mass ratio (A) / (C) and mass ratio (C) / (B) within the range of the above embodiment.

[0061] Table 1 shows the evaluation results for Examples 1 to 6. Good evaluation results were obtained for silica particle sedimentation (after impregnation) in all Examples 1 to 6. Regarding silica particle sedimentation (before impregnation), Examples 2 to 6, which included component (C) in the liquid composition, all showed better evaluation results than Example 1, which did not include component (C) in the liquid composition. Good evaluation results were obtained for the smoothness and powderiness of the skin after wiping in all Examples 1 to 6.

[0079] • Example 20 In Example 20, a nonwoven fabric with the same configuration as in Examples 1 and 2 was used as the sheet. In addition, Example 20 used a liquid composition composed of the components shown in Table 6 and its annotations.

[0083] Comparison Examples 1-3 In Comparative Examples 1 to 3, a nonwoven fabric with the same configuration as in Examples 1 and 2 was used as the sheet. In addition, Comparative Examples 1 to 3 each used a liquid composition composed of the components shown in Table 7 and its annotations. The liquid compositions used in Comparative Examples 1 to 3 differ from those used in Example 2 in the composition of component (B). The liquid composition used in Comparative Example 1 differs from the above embodiment in that it does not contain component (B). In Comparative Example 2, component (B') (KF-6011 (manufactured by Shin-Etsu Chemical Co., Ltd., PEG-11 methyl ether dimethicone, HLB: 14.5)), which has an HLB value greater than the upper limit of the above embodiment, was used instead of component (B) used in Example 2. In Comparative Example 3, component (B) common to Example 2 was used, but the content of component (B) in the liquid composition was less than the lower limit of the above embodiment.

[0084] Table 7 shows the mass ratios (A) / (B), (A) / (C), and (C) / (B) for the liquid compositions used in Comparative Examples 1 to 3. In all of the liquid compositions used in Comparative Examples 1 and 3, the mass ratios (A) / (B) and (C) / (B) were greater than the upper limit values ​​of the above embodiment. In addition, in the liquid composition used in Comparative Example 2, (C) / (B) was greater than the upper limit value of the above embodiment.

[0085] Table 7 shows the evaluation results for Comparative Examples 1 to 3. Regarding silica particle sedimentation (after impregnation), it was found that in all of the above Examples 1 to 20, better evaluation results were obtained than in Comparative Examples 1 and 2, which had insufficient content of component (B) in the liquid composition. Regarding silica particle sedimentation (before impregnation), Comparative Example 3, which used component (B) in small amounts, obtained better evaluation results than in Comparative Examples 1 and 2, which did not use component (B). This is thought to be because in Comparative Examples 1 and 2, component (A) was not coated with component (B), causing component (C) to be adsorbed onto component (A), and the thickening effect due to electrostatic repulsion of component (C) was not effectively obtained. Regarding the smoothness and powderiness of the skin after wiping, it was found that in each example, such as Example 2, which had a sufficient content of component (B), better evaluation results were obtained than in Comparative Examples 1 to 3, which had insufficient content of component (B).
