[0004] The emulsion cosmetic according to one embodiment of the present invention contains the following components (A) to (D): (A) silica particles, 0.5% by mass to 10% by mass; (B) modified silicone, 0.3% by mass to 4% by mass; (C) non-volatile oil that is liquid at 25°C, 20% by mass to 40% by mass; and (D) water, 5% by mass to 78% by mass.

[0006] In the cosmetics disclosed in Patent Documents 1 and 2, it is conceivable to increase the content of porous silica in order to further enhance the effect of suppressing discomfort caused by sweating. However, in cosmetics, there is a limit to the amount of porous silica that can be adhered to the skin, and if too much porous silica is adhered to the skin, problems such as poor compatibility with the skin and unnatural whitening can easily occur.

[0007] The present invention relates to enhancing the effect of suppressing discomfort caused by sweating in an emulsion cosmetic.

[0008] The following describes embodiments of the present invention. The present invention is not limited to the following embodiments, and various modifications can be made without departing from the spirit and scope of the present invention.

[0009] [Overall Structure of Emulsion Cosmetic] - Overview Structure The emulsion cosmetic X according to this embodiment is configured as a water-in-oil (W / O) emulsion. The emulsion cosmetic X is typically configured as a rinse-off type that is applied to bare skin without wiping and then rinsed off without wiping. A rinse-off type emulsion cosmetic X can be applied to the entire body, including the upper part of the body (e.g., shoulders), and then rinsed off with a shower or the like, i.e., rinsed off, so that it can be spread evenly over the upper and lower body, and the ingredients contained in the emulsion cosmetic X can remain on the skin even after dabbing with a towel or the like. The emulsion cosmetic X may also be a leave-on type that is applied to bare skin and not washed off. In the following description, "immediately after application" for a rinse-off type emulsion cosmetic X refers to the time after the emulsion cosmetic X has been rinsed off and the skin has been dabbed with a towel or the like.

[0010] Emulsion cosmetic X contains component (A), component (B), component (C), and component (D). Component (A) is composed of silica particles. Component (B) is composed of modified silicone. Component (C) is composed of a non-volatile oil that is liquid at 25°C. In this embodiment, "liquid" refers to being liquid at 25°C, and indicates, for example, that the viscosity at 25°C is 20,000 mPa·s or less. Component (D) is composed of water. FIG. 1 schematically shows the state of each component of emulsion cosmetic X after shaking and stirring before use. The oil phase, which is the external phase, is composed of component (C), and the aqueous phase, which is the internal phase, is composed of component (D). The silica particles that make up component (A) are dispersed in the oil phase while coated with the modified silicone that makes up component (B).

[0011] The unpleasant components that cause discomfort during sweating include water, salt, and lactic acid, which are components contained in sweat, as well as sebum secreted on the surface of the skin.

[0012] In contrast, in emulsion cosmetic X, the silica particles adsorb the salt and lactic acid contained in sweat and purify the sweat, thereby reducing the viscosity of the sweat and allowing the moisture that makes up the sweat to evaporate quickly. Furthermore, in emulsion cosmetic X, the silica particles also adsorb sebum, thereby suppressing the effects of sebum. Furthermore, in emulsion cosmetic X, the non-volatile oil that constitutes component (C) is blended in at a higher amount than in general compositions, allowing more silica particles to remain on the skin. In this way, the action of the silica particles in emulsion cosmetic X can suppress discomfort caused by sweating on the skin after application.

[0013] Furthermore, when emulsion cosmetic X is applied to the skin, the silica particles are coated on the skin with a hydrophobic, water-repellent film, as shown in Figure 2. The water-repellent film is composed of modified silicone (component (B)) and at least a portion of non-volatile oil (component (C)). As described above, emulsion cosmetic X allows a larger number of silica particles to remain on the skin, making it possible for the silica particles to form an uneven shape on the skin. Furthermore, with rinse-off emulsion cosmetic X, hydrophilic components such as surfactants, polyols, and polar oils are washed away, making it possible to more effectively obtain the water-repellent effect of the water-repellent film.

[0014] As shown in Figure 2, emulsion cosmetic X can effectively reduce sweat wettability through the synergistic effect of the water-repellent film and the lotus effect of the uneven surface formed by the silica particles. Therefore, emulsion cosmetic X can suppress the discomfort caused by sweat spreading on the skin. Furthermore, emulsion cosmetic X does not easily retain sweat on the skin after application, so the amount of sweat that needs to be purified by the action of silica can be reduced. Therefore, emulsion cosmetic X can maintain the effect of the silica particles for a longer period of time without increasing the amount of silica particles.

[0015] Component (A) As described above, the silica particles constituting component (A) have the effect of adsorbing unpleasant components such as salt and lactic acid contained in sweat, and sebum secreted on the surface of the skin. In emulsion cosmetic X, it is advantageous for the content of component (A) to be high in order to more effectively obtain the effect of adsorbing unpleasant components, while it is advantageous for the content of component (A) to be not too high in order to ensure compatibility with the skin and prevent the skin from appearing unnaturally white. From these perspectives, the content of component (A) in emulsion cosmetic X is from 0.5% to 10% by mass, preferably from 1% to 8% by mass, and more preferably from 2% to 5% by mass.

[0016] Examples of silica particles constituting component (A) include porous silica, nonporous silica, and hollow silica, and one or more selected from these can be used. In order to adsorb more salt, lactic acid, sebum, and the like, emulsion cosmetic X preferably includes component (A1) as component (A) composed of porous silica particles with an oil absorption of 250 mL / 100 g or more. In this case, in order to achieve a smooth, non-gritty feel on the skin, emulsion cosmetic X more preferably also includes component (A2) as component (A) composed of silica particles with an oil absorption of less than 250 mL / 100 g. The oil absorption can be measured in accordance with JIS K 5101-13-2.

[0017] In order to obtain a sufficient effect of adsorbing unpleasant components while maintaining a smooth, non-gritty feel on the skin, it is preferable that the components (A1) and (A2) are blended in a well-balanced manner in emulsion cosmetic X. Specifically, in emulsion cosmetic X, the mass ratio (A2) / (A1), which is the ratio of the mass of component (A2) to the mass of component (A1), is preferably 0.3 or more and 35 or less, more preferably 0.5 or more and 35 or less, even more preferably 0.5 or more and 10 or less, even more preferably 0.5 or more and 5 or less, and even more preferably 1 or more and 5 or less.

[0018] The particle size of the silica particles constituting component (A) is advantageously small in order to obtain a smooth feel on the skin to which emulsion cosmetic X has been applied, and is advantageously not too small in order to reduce the likelihood of the particles feeling rough to the touch. From these viewpoints, the average particle size of the silica particles constituting component (A) is preferably 1 μm or more and 15 μm or less, more preferably 2 μm or more and 12 μm or less, even more preferably 3 μm or more and 12 μm or less, and even more preferably 3 μm or more and 5 μm or less. Similarly, the average particle size of the silica particles constituting component (A1) is preferably 1 μm or more and 15 μm or less, more preferably 2 μm or more and 12 μm or less, even more preferably 3 μm or more and 12 μm or less, and even more preferably 3 μm or more and 5 μm or less. Similarly, the average particle size of the silica particles constituting component (A2) is preferably 1 μm or more and 15 μm or less, more preferably 2 μm or more and 12 μm or less, even more preferably 3 μm or more and 12 μm or less, and even more preferably 3 μm or more and 5 μm or less. In this embodiment, the particle size is the particle size measured using a Coulter Counter Multisizer (manufactured by Beckman Coulter, Inc.) according to a method conforming to JIS Z 8832:2010, and the average particle size is the volume-based median diameter (D50) obtained by measurement.

[0019] Component (B) The modified silicone that constitutes component (B) is a surfactant with relatively high hydrophobicity. In emulsion cosmetic X, the modified silicone functions as a water-in-oil emulsifier and, as shown in Figure 1, is thought to coat each silica particle, thereby imparting hydrophobicity to the surface of the silica particles. This allows emulsion cosmetic X to disperse the silica particles that constitute component (A) in the oil phase. The content of component (B) in emulsion cosmetic X is 0.3% by mass or more and 4% by mass or less, preferably 0.5% by mass or more and 3% by mass or less, and more preferably 1% by mass or more and 2% by mass or less.

[0020] Component (C) The non-volatile oil constituting component (C) preferably contains one or more types selected from known non-volatile oils. In this embodiment, "non-volatile" refers to the property that, when 1 g of the oil is spread on a 48 mm diameter glass petri dish and left at 25°C and normal pressure for 24 hours, the weight loss rate is 3% or less. The non-volatile oil constituting component (C) adheres to the skin in a dispersed state with silica particles, thereby retaining the silica particles on the skin. In emulsion cosmetic X, by incorporating a larger amount of component (C) than in a typical composition, more silica particles can be retained on the skin. On the other hand, in emulsion cosmetic X, it is advantageous not to include too much component (C) in order to avoid causing the skin to feel oily and sticky. From these perspectives, the content of component (C) in emulsion cosmetic X is preferably 20% by mass or more and 40% by mass or less, more preferably 25% by mass or more and 35% by mass or less, and even more preferably 28% by mass or more and 32% by mass or less.

[0021] When emulsion cosmetic X is formulated as a rinse-off type, a portion of component (C) is washed away, so it is preferable to incorporate a larger amount of component (C) than when it is formulated as a leave-on type. Therefore, the content of component (C) in rinse-off type emulsion cosmetic X is preferably 30% by mass or more and 40% by mass or less. The content of component (C) in leave-on type emulsion cosmetic X is preferably 20% by mass or more and 30% by mass or less.

[0022] In emulsion cosmetic X, component (C) is composed of at least one of component (C1) composed of a non-polar oil and component (C2) composed of a polar oil. The non-polar oil that constitutes component (C1) is hydrophobic and therefore functions as part of the water-repellent coating shown in Figure 2. On the other hand, the polar oil that constitutes component (C2) is hydrophilic and therefore, if it remains on the skin, it tends to interfere with the water-repellent effect of the water-repellent coating shown in Figure 2.

[0023] For this reason, in emulsion cosmetic X, in order to form a water-repellent coating that provides a high water-repellent effect, it is preferable that component (C) contains component (C1). Furthermore, in emulsion cosmetic X, the mass ratio (C1) / (C), which is the ratio of the mass of component (C1) to the mass of component (C), is more preferably 0.33 or more and 1 or less, and even more preferably 0.5 or more and 1 or less. Note that, although it is preferable that component (C) contains component (C1) in emulsion cosmetic X, component (C) may be composed only of component (C2), in which case the water-repellent coating is formed substantially only by the modified silicone that constitutes component (B).

[0024] In emulsion cosmetic X, it is preferable to blend components (A) and (C) in a balanced manner so that a predetermined amount of silica particles remains on the skin. Specifically, in emulsion cosmetic X, the mass ratio (C) / (A), which is the ratio of the mass of component (C) to the mass of component (A), is preferably 2 or more and 50 or less, more preferably 3 or more and 20 or less, and even more preferably 6 or more and 12 or less. Furthermore, in emulsion cosmetic X, it is preferable to blend components (A) and (C1) in a balanced manner so that a good water-repellent film can be formed. Specifically, in emulsion cosmetic X, the mass ratio (C1) / (A), which is the ratio of the mass of component (C1) to the mass of component (A), is preferably 2 or more and 50 or less, more preferably 3 or more and 20 or less, and even more preferably 6 or more and 12 or less.

[0025] Component (D) Component (D) in emulsion cosmetic X is composed of water. In emulsion cosmetic X, for example, purified water, ion-exchanged water, distilled water, etc. can be used as component (D). In emulsion cosmetic X, the remainder, excluding components other than component (D), can be composed of component (D). In emulsion cosmetic X, a high content of component (D) is advantageous for providing a fresh feeling upon application, and it is advantageous for emulsion stability that the content of component (D) is not too high. From these perspectives, the content of component (D) in emulsion cosmetic X is preferably 5% by mass or more and 78% by mass or less, more preferably 15% by mass or more and 42% by mass or less, and even more preferably 20% by mass or more and 35% by mass or less.

[0044] [Examples and Comparative Examples] - General Description Examples of the present invention will be described below, but the present invention should not be construed as being limited by these examples. In Examples 1 to 30 of the present invention and Comparative Examples 1 to 3, samples of emulsion cosmetics with different compositions were prepared, and evaluations were performed for each composition. In the tables shown below, the numerical values ​​listed for the components of the emulsion cosmetics indicate the content (% by mass) in the emulsion cosmetics. First, the evaluation method common to Examples 1 to 30 and Comparative Examples 1 to 3 will be described.

[0045] Measurement of contact angle and determination of contact angle score For the evaluation of contact angle, a sample of emulsion cosmetic was applied to a PMMA plate (5 × 5 cm, manufactured by Fuji Kasei Co., Ltd.) at a concentration of 1 mg / cm ２The solution was dripped onto the PMMA plate so that the surface was covered with water and applied with a finger. The PMMA plate was then rinsed with tap water for 5 seconds, and gently pressed with a towel to remove the surface water droplets, forming a coating film. Using an automatic contact angle meter DM501Hi (manufactured by Kyowa Interface Science Co., Ltd.), a 10 uL droplet of purified water was dripped onto the formed coating film using the sessile drop method to measure the contact angle of water. The contact angle was measured 30 seconds after dripping the purified water droplet. In this evaluation, purified water was used as the simulated sweat because it was confirmed that the contact angles of purified water and artificial sweat, which reproduces the components of sweat, were equivalent. The larger the contact angle, the less likely sweat will cling to the skin after sweating. The contact angle was evaluated using a five-point contact angle score: "1: 60° or less," "2: more than 60° and less than 70°," "3: more than 70° and less than 75°," "4: more than 75° and less than 80°," and "5: more than 80°."

[0046] - Smooth feeling (after sweating) For the evaluation of smooth feeling (after sweating), a sample of the emulsion cosmetic was applied at 1 mg / cm to an artificial leather (5 x 5 cm, Laforet black leather for experiments manufactured by Okamoto Chemicals Co., Ltd.). ２ The artificial leather was then exposed to running tap water for 5 seconds, and lightly pressed with a cloth (towel) to remove the water droplets on the surface, forming a coating film. Water was sprayed onto the coating film in the form of a mist (approximately 10 mg / cm) to simulate sweat. ２ Then, a sensory evaluation was conducted on the smooth feel of the coating film when touched. The smooth feel (after sweating) was evaluated using a 5-point scale: "1: Not smooth," "2: Not very smooth," "3: Slightly smooth," "4: Smooth," and "5: Very smooth."

[0047] - Smooth feeling (immediately after application) For the evaluation of smooth feeling (immediately after application), a sample of the emulsion cosmetic was applied at 1 mg / cm to an artificial leather (5 x 5 cm, Laforet black leather for experiments manufactured by Okamoto Chemicals Co., Ltd.). ２The solution was dropped onto the surface of the artificial leather so that the surface was covered with water and applied with a finger. The artificial leather was then rinsed with tap water for 5 seconds, and gently pressed with a cloth (towel) to remove the water droplets on the surface, forming a coating film. The resulting coating film was then subjected to a sensory evaluation to assess its smooth feel when touched. The smooth feel (immediately after application) was evaluated using a 5-point scale: "1: not smooth," "2: not very smooth," "3: slightly smooth," "4: smooth," and "5: very smooth."

[0048] - Absence of squeaking (immediately after application) For the evaluation of absence of squeaking (immediately after application), a sample of the emulsion cosmetic was applied at 1 mg / cm to an artificial leather (5 x 5 cm, Laforet black leather for experiments manufactured by Okamoto Chemical Products Co., Ltd.). ２ The solution was dropped onto the surface of the artificial leather so that the surface was covered with water and applied with a finger. The artificial leather was then rinsed with tap water for 5 seconds, and gently pressed with a cloth (towel) to remove the water droplets on the surface, forming a coating film. The resulting coating film was then subjected to a sensory evaluation to assess the creaking sensation felt when touched. The lack of creaking sensation (immediately after application) was evaluated using a five-point scale: "1: creaking", "2: slightly creaking", "3: not much creaking", "4: not creaking", and "5: not creaking at all".

[0049] - Non-oily feeling (immediately after application) For the evaluation of non-oily feeling (immediately after application), a sample of the emulsion cosmetic was applied at 1 mg / cm to an artificial leather (5 x 5 cm, Laforet black leather for experiments manufactured by Okamoto Chemicals Co., Ltd.). ２ The solution was dropped onto the surface of the artificial leather so that the surface was covered with water and applied with a finger. The artificial leather was then rinsed with tap water for 5 seconds, and gently pressed with a cloth (towel) to remove the water droplets on the surface, forming a coating film. A sensory evaluation was then conducted on the oily feel of the coating film when touched. The lack of oiliness (immediately after application) was evaluated using a 5-point scale: "1: oily," "2: slightly oily," "3: not very oily," "4: not oily," and "5: not oily at all."

[0050] Absence of unnatural whiteness (immediately after application) For the evaluation of the absence of unnatural whiteness (immediately after application), a sample of the emulsion cosmetic was applied at 1 mg / cm to an artificial leather (5 x 5 cm, Laforet black leather for experiments manufactured by Okamoto Chemicals Co., Ltd.). ２The artificial leather was then showered with tap water for 5 seconds, and gently pressed with a cloth (towel) to remove the water droplets on the surface, forming a coating film. The appearance (unnatural whiteness) of the formed coating film was then subjected to a sensory evaluation. The absence of unnatural whiteness (immediately after application) was evaluated using a 5-point scale: "1: unnatural whiteness present," "2: slightly unnatural whiteness present," "3: not much unnatural whiteness present," "4: no unnatural whiteness present," and "5: no unnatural whiteness present at all."

[0071] Evaluation as a leave-on type While the samples of Examples 1 to 30 were evaluated as rinse-off types above, the samples of Examples 1, 19, and 20, which differ from one another in the content of component (C), were also evaluated as leave-on types. In each evaluation as a leave-on type, the step of "running a PMMA plate under shower-like tap water for 5 seconds, then lightly pressing with a cloth (towel) to remove water droplets from the surface" in each of the above evaluation methods was omitted; in other words, the coating film before rinsing was evaluated.

[0072] Table 6 shows the evaluation results of the samples of Examples 1, 19, and 20 as leave-on types. With regard to the contact angle score, good evaluation results were obtained for all of Examples 1, 19, and 20. With regard to the dry feeling (after sweating), good evaluation results were obtained for all of Examples 1, 19, and 20, but particularly good evaluation results were obtained for Examples 1 and 19, which did not contain a large amount of component (C). With regard to the dry feeling (immediately after application), good evaluation results were obtained for all of Examples 1, 19, and 20, but particularly good evaluation results were obtained for Examples 1 and 19, which did not contain a large amount of component (C). With regard to the absence of greasy feeling (immediately after application), good evaluation results were obtained for all of Examples 1, 19, and 20. With regard to the absence of oiliness (immediately after application), good evaluation results were obtained for all of Examples 1, 19, and 20, but particularly good evaluation results were obtained for Examples 1 and 19, which did not contain a large amount of component (C). With regard to unnatural whiteness (immediately after application), good evaluation results were obtained for all of Examples 1, 19, and 20.

[0074] Evaluation of tack value (after sweating) The tack value (after sweating) was evaluated for the samples according to Examples 1, 15, 23, and 24 and Comparative Examples 1 to 3. The tack value is a value indicating adhesiveness and serves as an index for evaluating stickiness of the skin after sweating. In the evaluation of the tack value, the preparation was applied at 1 mg / cm to an area of ​​5 cm x 5 cm on the inside of the forearm. ２ The solution was dripped onto the PMMA plate so that the surface was covered with a drop of water and applied with a finger. The PMMA plate was then rinsed with tap water for 5 seconds, and gently pressed with a cloth (towel) to remove the water droplets on the surface, forming a coating film. The patient was placed in an environment-variable chamber set at 30°C and 80% RH, and after remaining in a resting state for 15 minutes, the tack value of the applied area was measured using a friction tester (Handy Rub Tester TL701, manufactured by Trinity Lab Co., Ltd.). The tack value was determined by pressing the probe of the friction tester perpendicularly to the skin and the attractive force when pulling it away. The higher the tack value, the more sticky the skin. The tack value was evaluated using a 5-level tack value score: "greater than 1:13," "greater than 2:10 and 13 or less," "greater than 3:8 and 10 or less," "greater than 4:5 and 8 or less," and "5:5 or less."

[0075] Table 7 shows the evaluation results of the tack value of the samples according to Examples 1, 15, 23, and 24 and Comparative Examples 1 to 3. With regard to the tack value score, the samples according to Examples 1, 15, 23, and 24 all gave better results than the samples according to Comparative Examples 1 to 3, and particularly good evaluation results were obtained in Examples 1 and 15, which did not contain component (C2).
