[0013] Figure 1 is a schematic diagram showing one embodiment of the composition of the present invention. Figure 2 is a schematic diagram showing one embodiment in which the composition of the present invention further comprises an aqueous phase containing water. Figure 3 is a schematic diagram showing another embodiment in which the composition of the present invention further comprises an aqueous phase containing water. Figure 4 is a micrograph of the state of oil droplets in the composition of Example 1. Figure 5 is a micrograph of the state of oil droplets in the composition of Example 3. Figure 6 is a micrograph of the state of oil droplets in the composition of Comparative Example 1.

[0014] The embodiments of the present invention will be described in detail below. However, the present invention is not limited to the embodiments described below, and can be implemented with various modifications within the scope of the essence of the invention.

[0015] The composition of the present invention comprises a first oil phase containing a polar oil, a second oil phase containing a silicone oil, and an amphiphilic compound having a portion that is compatible with the polar oil and a portion that is compatible with the silicone oil, wherein the second oil phase is dispersed in the first oil phase in the form of oil droplets, or the first oil phase is dispersed in the second oil phase in the form of oil droplets.

[0016] Figure 1 is a schematic diagram showing one embodiment of the composition of the present invention.

[0017] As shown in Figure 1, the composition of the present invention comprises a first oil phase, a second oil phase, and an amphiphilic compound. Here, the first oil phase contains a polar oil, the second oil phase contains a silicone oil, and the amphiphilic compound has a portion that is compatible with the polar oil and a portion that is compatible with the silicone oil. This amphiphilic compound is present at the interface between the first oil phase and the second oil phase, and the second oil phase is dispersed in the first oil phase in the form of oil droplets (i.e., the configuration shown in Figure 1(a)), or the first oil phase is dispersed in the second oil phase in the form of oil droplets (i.e., the configuration shown in Figure 1(b)). These configurations shown in Figures 1(a) and 1(b) can also be described as an oil-in-oil emulsion state.

[0018] Therefore, the composition of the present invention is capable of forming an oil-in-oil emulsion unlike any other, and possesses the characteristics of a novel emulsifying composition.

[0019] Furthermore, in order to disperse the second or first oil phase in the first or second oil phase as oil droplets, it is preferable to select oils that are poorly miscible or incompatible with each other. Here, "miscible" refers to the property of two or more substances mixing uniformly and forming a single phase. In contrast, "poorly miscible" or "incompatible" refers to the property of two or more substances not mixing uniformly, or not mixing at all and forming two or more phases.

[0020] Specifically, for example, two or more oils with a large difference in polarity, or two or more oils that differ significantly in molecular weight or structure, are highly likely to be incompatible or incompatible. The difference in polarity can be appropriately selected from two or more oils with an IOB value difference of 0.1 or more, 0.2 or more, 0.3 or more, 0.4 or more, or 0.5 or more, as defined below. More specifically, examples of combinations of two or more oils with a large difference in polarity include, but are not limited to, polar oils (especially polar oils with an IOB value of 0.1 or more, 0.2 or more, 0.3 or more, 0.4 or more, or 0.5 or more) and silicone oils (especially silicone oils with an IOB value of 0.05 or less). Also, examples of two or more oils that differ significantly in molecular weight or structure include, but are not limited to, linear oils and branched oils. Furthermore, examples of combinations of two types of oil with a large difference in viscosity include, but are not limited to, combinations of polar oil and silicone oil with viscosity of 1 cSt or more, 2 cSt or more, 6 cSt or more, 20 cSt or more, 50 cSt or more, 300 cSt or more, 5000 cSt or more, or 10000 cSt or more.

[0021] Furthermore, whether the second oil phase is dispersed in the first oil phase as oil droplets or the first oil phase is dispersed in the second oil phase as oil droplets can be controlled, for example, by adjusting the type of amphiphilic compound used and / or the content of the first oil phase and the content of the second oil phase.

[0022] More specifically, for example, by making the amphiphilic compound have a greater affinity for the first oil phase than for the second oil phase, it becomes easier to disperse the second oil phase in the form of oil droplets within the first oil phase. Furthermore, by making the amphiphilic compound have a greater affinity for the second oil phase than for the first oil phase, it becomes easier to disperse the first oil phase in the form of oil droplets within the second oil phase. In addition, for example, by making the content of the first oil phase greater than the content of the second oil phase, it becomes easier to disperse the second oil phase in the form of oil droplets within the first oil phase. Furthermore, by making the content of the first oil phase the same as or less than the content of the second oil phase, it becomes easier to disperse the first oil phase in the form of oil droplets within the second oil phase.

[0023] The composition of the present invention may be in liquid, semi-solid, or solid form. "Liquid" refers to a state of matter that is fluid at normal pressure (1 atm) and room temperature (25°C) and conforms to the shape of the container. "Semi-solid" refers to a state of matter that maintains a constant shape at normal pressure (1 atm) and room temperature (25°C) unless an external force is applied, but is deformable in response to an external force (e.g., an external force of 0.1 MPa or less). "Solid" refers to a state of matter that does not deform even when a certain external force (e.g., an external force of 0.1 MPa or less) is applied at normal pressure (1 atm) and room temperature (25°C).

[0024] The composition of the present invention is in liquid or semi-solid form, and the composition of the present invention may further comprise (i) an aqueous phase containing water and an amphiphilic compound further having a portion that is compatible with water, or (ii) an aqueous phase containing water and an emulsifier with an HLB value of less than 10, wherein the aqueous phase is dispersed in the first oil phase in the form of water droplets when the second oil phase is dispersed in the first oil phase in the form of oil droplets, or the aqueous phase is dispersed in the second oil phase in the form of water droplets when the first oil phase is dispersed in the second oil phase in the form of oil droplets.

[0025] For example, Figure 2 is a schematic diagram showing one embodiment in which the composition of the present invention further comprises an aqueous phase containing water.

[0026] As shown in Figure 2, the composition of the present invention comprises a first oil phase, a second oil phase, and an amphiphilic compound aqueous phase. Here, the first oil phase contains a polar oil, and the second oil phase contains a silicone oil. In this case, the composition of the present invention may further comprise (i) an aqueous phase containing water and an amphiphilic compound having a water-affinity portion, or (ii) an aqueous phase containing water and an emulsifier with an HLB value of less than 10. In the embodiment of Figure 2(a), the amphiphilic compound having a water-affinity portion is present at the interface between the first oil phase and the second oil phase, and at the interface between the first oil phase and the aqueous phase, with the second oil phase dispersed in the first oil phase in the form of oil droplets and the aqueous phase dispersed in the form of water droplets. In the embodiment shown in Figure 2(b), an amphiphilic compound further having a water-affinity portion is present at the interface between the first oil phase and the second oil phase, and at the interface between the second oil phase and the water phase, with the first oil phase dispersed in the second oil phase as oil droplets and the water phase dispersed in the second oil phase as water droplets. Such embodiments as shown in Figures 2(a) and 2(b) can also be described as an oil-in-water (oil and water) type emulsion state. Although not shown, an emulsifier with an HLB value of less than 10 may be used instead of the "amphiphilic compound" in Figures 2(a) and 2(b). In this invention, the HLB value (Hydrophile-Lipophile Balance) can be defined by the Griffin method. However, in the case of surfactants having an oxypropylene structure, it can be defined by the Kawakami method.

[0027] Here, the HLB value of an emulsifier with an HLB value of less than 10 may more specifically be, for example, less than 10, 9.5 or less, 9.0 or less, 8.5 or less, 8.0 or less, 7.5 or less, 7.0 or less, 6.5 or less, 6.0 or less, 5.5 or less, or 5.0 or less, and may also be greater than 0, 1.0 or more, 1.5 or more, 2.0 or more, 2.5 or more, 3.0 or more, or 3.5 or more.

[0028] The composition of the present invention may also be in liquid or semi-solid form, and the composition of the present invention may further comprise (i) an aqueous phase containing water and an amphiphilic compound further having a portion that is compatible with water, (ii) an aqueous phase containing water and an emulsifier with an HLB value of 10 or more, or (iii) an aqueous phase containing water and an acrylic emulsifier, wherein the second oil phase is dispersed in the first oil phase in the form of oil droplets, and the first oil phase is dispersed in the aqueous phase in the form of oil droplets, or the second oil phase is dispersed in the second oil phase in the form of oil droplets, and the second oil phase is dispersed in the aqueous phase in the form of oil droplets.

[0029] For example, Figure 3 is a schematic diagram showing another embodiment in which the composition of the present invention further comprises an aqueous phase containing water.

[0030] As shown in Figure 3, the composition of the present invention comprises a first oil phase, a second oil phase, and an amphiphilic compound. Here, the first oil phase contains a polar oil, and the second oil phase contains a silicone oil. In this case, the composition of the present invention may further comprise (i) an aqueous phase containing water and an amphiphilic compound further having a water-affinity portion, (ii) an aqueous phase containing water and an emulsifier with an HLB value of 10 or higher, or (iii) an aqueous phase containing water and an acrylic emulsifier. In the embodiment of Figure 3(a), the amphiphilic compound further having a water-affinity portion is present at the interface between the first oil phase and the second oil phase, the second oil phase is dispersed in the first oil phase in the form of oil droplets, and the amphiphilic compound further having a water-affinity portion is also present at the interface between the first oil phase and the aqueous phase, and the first oil phase is dispersed in the aqueous phase in the form of oil droplets. In the embodiment shown in Figure 3(b), an amphiphilic compound having a water-affinity portion is present at the interface between the first oil phase and the second oil phase, and the first oil phase is dispersed in the second oil phase as oil droplets. Furthermore, an amphiphilic compound having a water-affinity portion is also present at the interface between the second oil phase and the water phase, and the second oil phase is dispersed in the water phase as oil droplets. Such embodiments as shown in Figures 3(a) and 3(b) can also be described as an oil-in-water (oil-in-oil) type emulsion state. Although not shown, an emulsifier with an HLB value of 10 or higher or an acrylic emulsifier may be used instead of the "amphiphilic compound" in Figures 3(a) and 3(b).

[0031] Here, the HLB value of an emulsifier with an HLB value of 10 or higher may more specifically be, for example, 10 or higher, 11 or higher, 12 or higher, 13 or higher, 14 or higher, or 15 or higher, and may also be 20 or lower, 19 or lower, 18 or lower, 17 or lower, 16 or lower, or 15 or lower.

[0032] The composition of the present invention may also be in solid form, and after being applied to the surface of an object, the second oil phase may be dispersed in the first oil phase in the form of oil droplets.

[0033] In this case, before applying the composition of the present invention to the surface of the object, either of the embodiments shown in Figure 1(a) and Figure 1(b) described above may be used, but the embodiment shown in Figure 1(a) is preferred.

[0034] Furthermore, when the composition of the present invention is in solid form, it is preferable that the content of silicone oil in the second oil phase is greater than the content of polar oil in the first oil phase. More specifically, for example, the ratio of the content of polar oil in the first oil phase to the content of silicone oil in the first oil phase (content of polar oil / content of silicone oil) may be 0.10 or more, 0.20 or more, 0.25 or more, 0.30 or more, 0.35 or more, or 0.4 or more, and may also be less than 0.60, 0.55 or less, 0.50 or less, 0.45 or less, or 0.40 or less.

[0035] Furthermore, when the composition of the present invention is in solid form, it is preferable that the amphiphilic compound having a portion that is compatible with polar oils and a portion that is compatible with silicone oils is different from the amphiphilic compound used when the composition of the present invention described above is in liquid or semi-solid form (i.e., an amphiphilic compound having a portion that is compatible with water).

[0036] In this invention, the pressure during coating (i.e., coating pressure) is not particularly limited and may be, for example, 300 Pa or more, 400 Pa or more, 500 Pa or more, 600 Pa or more, 700 Pa or more, or 800 Pa or more, or 7000 Pa or less, 5000 Pa or less, 2000 Pa or less, 1800 Pa or less, 1500 Pa or less, 1200 Pa or less, or 1000 Pa or less. The method for measuring the coating pressure is not particularly limited and may be, for example, a gauger, or more specifically, a load cell.

[0037] In any form of the composition of the present invention described above, the oil phase is dispersed in the form of oil droplets. For example, if the polar oil contains an ultraviolet absorber, the ultraviolet absorber can not only absorb ultraviolet rays but also scatter them, thereby further improving the ultraviolet protection effect.

[0038] The following describes in detail each component that may be contained in the composition of the present invention.

[0039] <First Oil Phase>The composition of the present invention contains a first oil phase. The first oil phase contains a polar oil, preferably containing a polar oil as a main component. Here, the "main component" refers to a component in which the polar oil shows the highest ratio with respect to the total mass of the first oil phase. For example, when the polar oil shows 50% by mass or more with respect to the total amount of the first oil phase, it can be said that "the first oil phase contains a polar oil as a main component". Note that the first oil phase may contain one type of polar oil or a combination of two or more types of polar oils.

[0040] In the present invention, the "polar oil" refers to an oil having a high polarity among oils that can be used in cosmetics other than silicone oil. For example, the IOB value may be 0.05 or more, 0.10 or more, 0.15 or more, 0.20 or more, 0.25 or more, or 0.30 or more, and may also be an oil having 0.80 or less, 0.75 or less, 0.70 or less, 0.65 or less, or 0.60 or less. Note that the IOB value is an abbreviation of Inorganic / Organic Balance (inorganicity / organicity ratio), which is a value representing the ratio of the inorganic value to the organic value and is an index indicating the degree of polarity of an organic compound. Specifically, the IOB value is expressed as IOB value = inorganic value / organic value. For each of the "inorganic value" and "organic value", for example, the "organic value" is 20 for one carbon atom in the molecule, and the "inorganic value" is 100 for one hydroxyl group. The "inorganic value" and "organic value" corresponding to various atoms or functional groups are set, and the IOB value of the organic compound can be calculated by integrating the "inorganic value" and "organic value" of all atoms and functional groups in the organic compound (see, for example, Yoshiaki Koda, "Organic Conceptual Diagram - Basics and Applications -", pp. 11-17, Sankyo Publishing, issued in 1984). However, the polyorganosiloxane having a benzalmalonate functional group described later is classified as an "ultraviolet absorber" according to the present invention, that is, a "polar oil" as an exception.

[0041] Specifically, the polar oil can contain at least one of an ultraviolet absorber (particularly an oily ultraviolet absorber) and an ester oil. From the viewpoint of imparting an ultraviolet protection effect to the composition of the present invention, the polar oil preferably contains an ultraviolet absorber, particularly an oily ultraviolet absorber.

[0059] For example, with respect to the total amount of the composition of the present invention, the first oil phase may be, for example, 1.0% by mass or more, 5.0% by mass or more, 10% by mass or more, 20% by mass or more, 30% by mass or more, 40% by mass or more, 50% by mass or more, 80% by mass or more, 70% by mass or more, or 80% by mass or more, or 90% by mass or less, 80% by mass or less, 70% by mass or less, 60% by mass or less, 50% by mass or less, 40% by mass or less, 30% by mass or less, 20% by mass or less, or 10% by mass or less.

[0060] Furthermore, the content of polar oil in the composition of the present invention is not particularly limited, and may be 1.0% by mass or more, 5.0% by mass or more, 10% by mass or more, 20% by mass or more, 30% by mass or more, 40% by mass or more, 50% by mass or more, 80% by mass or more, 70% by mass or more, or 80% by mass or more, relative to the total amount of the composition, or it may be 90% by mass or less, 80% by mass or less, 70% by mass or less, 60% by mass or less, 50% by mass or less, 40% by mass or less, 30% by mass or less, 20% by mass or less, or 10% by mass or less.

[0061] The content of the first oil phase and the content of the polar oil may be adjusted as appropriate to suit the desired form of the present invention (for example, liquid, semi-solid, or solid), the presence or absence of an aqueous phase, or the type of emulsion.

[0062] Furthermore, the first oil phase may contain other hydrophobic components (particularly other oily components dissolved in the polar oil) in addition to the polar oil. The other oily components dissolved in the polar oil are preferably immiscible with the silicone oil contained in the second oil phase component, or are blended in an amount that is immiscible with the silicone oil contained in the second oil phase component. The other oily components dissolved in the polar oil are particularly preferably non-volatile oils, and more preferably non-volatile oils that are immiscible with the silicone oil contained in the second oil phase component. It is even more preferable that this non-volatile oil is blended in an amount that is immiscible with the silicone oil contained in the second oil composition.

[0063] For example, the first oil phase may contain hydrocarbons such as isododecane as other oily components dissolved in the polar oil. Preferably, the hydrocarbon is included in an amount of 5.0% by mass or less, 4.0% by mass or less, 3.0% by mass or less, 2.0% by mass or less, or 1.0% by mass or less, relative to the whole composition. Furthermore, if the first oil phase contains hydrocarbons, it is preferable that the silicone oil included in the second oil phase has a high viscosity (for example, 6 cSt or more, 20 cSt or more, or 100 cSt or more).

[0064] Furthermore, when hydrocarbons such as isododecane are added, the distribution coefficient K between the second and first oil phases of the hydrocarbon determines whether it is distributed to the first or second oil phase. （第２の油相／第１の油相） It can be evaluated based on K. （第２の油相／第１の油相） If it is less than 1, it is preferentially distributed to the first oil phase, K （第２の油相／第１の油相） If the value is greater than 1, it will be preferentially distributed to the second oil phase. （第２の油相／第１の油相） If the value is 1, the oil will be distributed equally between the first oil phase and the second oil phase.

[0065] <Second Oil Phase> The composition of the present invention includes a second oil phase. The second oil phase contains silicone oil, preferably as a main component. Here, "main component" refers to the component in which silicone oil accounts for the highest proportion relative to the total mass of the second oil phase. For example, if silicone oil accounts for 50% by mass or more of the total amount of the second oil phase, it can be said that "the first oil phase contains silicone oil as a main component." The second oil phase may contain one type of silicone oil, or it may contain a combination of two or more types of silicone oil.

[0066] In the composition of the present invention, the silicone oil may be a non-volatile silicone oil, a volatile silicone oil, or a mixture thereof. Of these, the silicone oil is preferably non-volatile.

[0067] In this invention, "volatile" refers to a substance whose volatile content exceeds 5% when left at atmospheric pressure and 105°C for 3 hours. In this disclosure, "non-volatile" refers to a substance whose volatile content is 5% or less when left at 105°C for 3 hours. From the viewpoint of further demonstrating the effects of this invention, the volatile content that serves as a guideline for non-volatility is preferably 5.0% or less, 4.0% or less, or 3.0% or less. Here, the volatile content refers to the value of the weight change rate measured by gravimetric method after placing filter paper on a glass petri dish and dropping approximately 0.2 g of the sample onto it. In this invention, the above-mentioned "polar oil" is treated as "non-volatile oil".

[0068] In the composition of the present invention, the silicone oil may be selected from linear, branched, or cyclic silicone oils. More specifically, examples of silicone oils include, but are not limited to, dimethicone (also called "methylpolysiloxane"), methylpolycyclosiloxane, methylhydrogenpolysiloxane, dimethylsiloxane, dimethylsiloxane-methyl (POE)siloxane copolymer, highly polymerized methylpolysiloxane, dimethylsiloxane-methyl (POP)siloxane copolymer, tetradecamethylhexasiloxane, octamethyltrisiloxane, dimethylsiloxane-methylcetyloxysiloxane copolymer, decamethyltetrasiloxane, cyclopentasiloxane, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane, hexadecamethylcycloheptasiloxane, and the like. Of these, the silicone oil preferably contains at least one selected from the group consisting of non-volatile dimethicone (for example, those with a concentration of 5 cSt or more, 6 cSt or more, 10 cSt or more, 20 cSt or more, 30 cSt or more, 50 cSt or more, 100 cSt or more, 300 cSt or more, 5000 cSt or more, or 10000 cSt or more, as well as those with a concentration of 10000 cSt or less, 5000 cSt or less, 1000 cSt or less, 500 cSt or less, or 300 cSt or less).

[0069] In the present invention, the content of the second oil phase is not particularly limited and may be adjusted as follows, for example.

[0070] For example, with respect to the total amount of the composition of the present invention, the second oil phase may be, for example, 1.0% by mass or more, 5.0% by mass or more, 10% by mass or more, 20% by mass or more, 30% by mass or more, 40% by mass or more, 50% by mass or more, 80% by mass or more, 70% by mass or more, or 80% by mass or more, or 90% by mass or less, 80% by mass or less, 70% by mass or less, 60% by mass or less, 50% by mass or less, 40% by mass or less, 30% by mass or less, 20% by mass or less, or 10% by mass or less.

[0071] Furthermore, in the composition of the present invention, the content of silicone oil (preferably non-volatile silicone oil) contained in the second oil phase is not particularly limited, and may be 1.0% by mass or more, 3.0% by mass or more, 5.0% by mass or more, 10% by mass or more, 20% by mass or more, 30% by mass or more, 40% by mass or more, 50% by mass or more, 80% by mass or more, 70% by mass or more, or 80% by mass or more, relative to the total amount of the composition, or 90% by mass or less, 80% by mass or less, 70% by mass or less, 60% by mass or less, 50% by mass or less, 40% by mass or less, 30% by mass or less, 20% by mass or less, or 10% by mass or less.

[0072] The second oil phase may further contain other hydrophobic components (in particular, other oily components dissolved in the silicone oil) in addition to the silicone oil. However, if the silicone oil contained in the second oil phase, especially the non-volatile silicone oil, is poorly miscible or incompatible with the polar oil contained in the first oil phase, there are no particular restrictions on the other oily components dissolved in the silicone oil.

[0073] The content of the second oil phase and the content of silicone oil may be adjusted as appropriate to suit the desired form of the present invention (for example, liquid, semi-solid, or solid), the presence or absence of an aqueous phase, or the type of emulsion.

[0074] <Aqueous Phase> The composition of the present invention may include an aqueous phase. In particular, if the composition of the present invention is in a liquid or semi-solid state, the composition of the present invention includes an aqueous phase.

[0075] In the present invention, the aqueous phase contains water, preferably as the main component. Here, "main component" refers to the component in which water accounts for the highest proportion of the total mass of the aqueous phase. For example, if water accounts for 50% or more by mass of the total amount of the aqueous phase, it can be said that "the aqueous phase contains water as the main component." Of course, if the composition of the present invention contains an aqueous phase, the aqueous phase does not have to contain water substantially.

[0076] (Water) There are no particular restrictions on the type of water used; for example, it may be water used in cosmetics and quasi-drugs. For example, deionized water, distilled water, ultrapure water, and tap water can be used.

[0137] Furthermore, the cosmetic composition according to the present invention may be a two-layer type that is shaken and / or mixed before use, or it may be a type that is used as is.

[0138] <Manufacturing Method> The composition or cosmetic composition of the present invention is not particularly limited and can be manufactured by conventional methods.

[0139] Furthermore, a method for producing the composition of the present invention when it is in a liquid or semi-solid state may include, for example, providing a first composition comprising a first oil phase containing a polar oil, a second oil phase containing a silicone oil, and an amphiphilic compound ("triphiphilic compound") having a portion that is compatible with polar oil, a portion that is compatible with silicone oil, and a portion that is compatible with water, wherein the second oil phase is dispersed in the first oil phase in the form of oil droplets, or the first oil phase is dispersed in the second oil phase in the form of oil droplets; providing an aqueous phase; and mixing the first composition with the aqueous phase.

[0140] More specifically, the first composition can be obtained, for example, by preparing a first oil phase component containing a polar oil and a first oil phase component containing a silicone oil, adding a triphyllophilic compound, and emulsifying them by a conventional method.

[0141] Furthermore, providing an aqueous phase can be done, for example, by mixing water and optionally added aqueous components to prepare an aqueous phase component.

[0142] Then, by mixing the first composition with the aqueous phase, a liquid or semi-solid composition of the present invention can be prepared.

[0143] Furthermore, whether the composition of the present invention becomes a mixed emulsion state in oil (oil and water) as shown in Figures 2(a) and 2(b), or an emulsion state in water (oil in oil) as shown in Figures 3(a) and 3(b), can be adjusted, for example, by the emulsifier (surfactant) used. More specifically, for example, when an emulsifier with a relatively low HLB value (for example, an HLB value of less than 10) is used, the composition of the present invention tends to become a mixed emulsion state in oil (oil and water). Conversely, when an emulsifier with a relatively high HLB value (for example, an HLB value of 10 or more) is used, the composition of the present invention tends to become an emulsion state in water (oil in oil). Furthermore, when using common emulsifiers used to prepare oil-in-water compositions (for example, acrylic emulsifiers, and more specifically, (acrylates / alkyl acrylate (C10-30)) crosspolymer, etc.), the compositions of the present invention tend to form an emulsion state in water (oil in oil).

[0144] The present invention will be further explained with reference to the following examples, but the present invention is not limited to these examples. Unless otherwise specified, the amounts of the ingredients are expressed in mass percent.

[0145] Examples 1-15 and Comparative Examples 1-4: Based on the formulations in Table 1, liquid compositions for Examples 1-15 and Comparative Examples 1-4 were prepared.

[0146] More specifically, the first oil phase, the second oil phase, and the amphiphilic compound were mixed at 25°C to prepare the solution.

[0147] For each of the obtained compositions, the dispersion state of the first and second oil phases, the compatibility between the first and second oil phases, the state of the oil droplets, and the stability of the oil droplets (state of the oil droplets after 1 hour) were confirmed using an optical microscope. The results are shown in Table 2.

[0148]

[0149]

[0150] As is clear from the results in Table 2, in all of the compositions of Examples 1 to 15, it was confirmed that the second or first oil phase was dispersed in the first or second oil phase in the form of oil droplets.

[0151] On the other hand, in all of the compositions of Comparative Examples 1 to 4, the first oil phase and the second oil phase became miscible, and a dispersed state of oil droplets could not be obtained. Furthermore, regarding the miscibility of the oil phases in the compositions of Comparative Examples 1 to 4, tests were conducted by changing the ratio of the first oil phase and the second oil phase, but the results still showed that the two phases were miscible. In addition, a method of mixing without adding an amphiphilic compound was attempted, but similar miscibility occurred.

[0152] For reference, a micrograph of the oil droplet state of Example 1 (immediately after preparation) is shown in Figure 4, a micrograph of the oil droplet state of Example 3 (immediately after preparation) is shown in Figure 5, and a micrograph of the state of Comparative Example 1 (immediately after preparation) is shown in Figure 6.

[0153] Examples 16-19 and Comparative Examples 5-8: Based on the formulations in Table 3, liquid compositions for Examples 16-19 and Comparative Examples 5-8 were prepared.

[0154] More specifically, the solution was prepared by mixing the first oil phase, the second oil phase, and an amphiphilic compound at 25°C, and then adding an aqueous phase.

[0155] For each of the obtained compositions, the dispersion state of the first and second oil phases, and the state of the oil droplets (immediately after preparation) were confirmed in the same manner as described above. The confirmation results are shown in Table 3.

[0156]

[0157] As is clear from the results in Table 3, in all of the compositions of Examples 16 to 19, it was confirmed that the second or first oil phase was dispersed in the first or second oil phase in the form of oil droplets, and that the aqueous phase was also dispersed in the form of water droplets in the first or second oil phase, which was the outer phase. In other words, it was found that the compositions of Examples 16 to 19 are oil-in-water (oil and water) type emulsion compositions.

[0158] In contrast, it was found that the compositions of Comparative Examples 5 to 8 all failed to achieve a dispersed state of oil droplets. The reason for this is presumed to be as follows: In the examples, the amphiphilic compounds were evenly distributed during the emulsification of water and the formation of an oil-in-oil emulsion, resulting in the formation of oil droplets and water droplets. In contrast, in Comparative Examples 5 to 8, the amphiphilic substances had a high affinity for either water or oil, meaning that the distribution balance was poor, and therefore, a dispersed state could not be properly formed.

[0159] Examples 20 and 21 and Comparative Example 9: Based on the formulations in Table 4, liquid compositions for Examples 20 and 21 and Comparative Example 9 were prepared.

[0160] More specifically, the following preparations were made: (i) Preparation of the oil phase The first oil phase components (components 15-20 and 22-24 in Table 4) were mixed, and then the second oil phase component (component 21 in Table 4) and an amphiphilic substance (component 25 in Table 4) were added and mixed. Note that the dimethicone in component 21 was 6 cs. (ii) Preparation of the aqueous phase The aqueous phase components (components 1-14 in Table 4) were mixed to prepare the aqueous phase. (iii) Emulsification Emulsification was performed by adding (i) to the system in (ii). (iv) Others Other components (components 26-28 in Table 4) were added to the system in (iii) to prepare the aqueous phase.

[0161] For each of the obtained compositions, the compatibility of the first oil phase and the second oil phase was evaluated in the same manner as described above, and the evaluation results are shown in Table 4.

[0162] Furthermore, each of the obtained compositions was applied to a PMMA plate of simulated skin, i.e., a PMMA plate (SPF MASTER® PA01, manufactured by Shiseido Co., Ltd.) having irregularities corresponding to skin furrows, and the absorbance peak value at 300 nm after application was determined. The results are shown in Table 4. The absorbance was measured using a spectrophotometer (U-4150 self-recording spectrophotometer, manufactured by Hitachi, Ltd.).

[0163]

[0164] As is clear from the results in Table 4, the compositions of Examples 20 and 21 showed a higher peak absorbance at 300 nm compared to Comparative Example 9, indicating improved UV protection. From these results, it is considered that in the compositions of Examples 20 and 21, the dispersion of oil droplets of the second oil component in the polar oil containing the UV absorber resulted in not only UV absorption by the UV absorber but also UV scattering by the oil droplets of the second oil component, further improving the UV protection effect. Furthermore, it was found that Example 21 achieved the highest UV protection effect.

[0165] Examples 20-1 and 21-1 and Comparative Example 9-1: Liquid compositions of Examples 20-1 and 21-1 and Comparative Example 9-1 were prepared in the same manner as in Examples 20 and 21 and Comparative Example 9, except that 4.8% by mass of ethylhexyl methoxycinnamate and 0.2% by mass of cresil methoxycinnamate were used as component 15 in the formulations of Table 4.

[0166] Each of the obtained compositions was measured in the same manner as in Examples 20 and 21 and Comparative Example 9, and the measurement results are shown in Table 4-1.

[0167]

[0168] As is clear from the results in Table 4-1, the compositions of Examples 20-1 and 21-1 showed a higher peak absorbance at 300 nm compared to Comparative Example 9-1, indicating improved UV protection. From these results, it is considered that in the compositions of Examples 20-1 and 21-1, the dispersion of oil droplets of a second oil component in the polar oil containing the UV absorber resulted in improved UV protection not only due to UV absorption by the UV absorber but also due to the scattering effect of the oil droplets of the second oil component. Furthermore, it was found that Example 21-1 achieved the highest UV protection effect.

[0169] Examples 22-28 and Comparative Examples 10 and 11: Based on the formulations in Table 5, solid compositions for Examples 22-28 and Comparative Examples 10 and 11 were prepared.

[0170] Since the obtained compositions were solids, it was impossible to observe the state of the oil droplets or dispersion. Therefore, the absorbance peak value at 300 nm was determined, as in the case of Table 4 above. The results are shown in Table 5.

[0171]

[0172] As is clear from the results in Table 5, the compositions of Examples 22 to 28 showed a higher peak absorbance at 300 nm compared to Comparative Examples 10 and 11, indicating improved UV protection. This result suggests that in the compositions of Examples 22 to 28, the dispersion of polar oil containing UV absorbers not only absorbed UV rays but also scattered them. As a result, the UV protection effect was further improved compared to Comparative Examples 10 and 11. Furthermore, it was found that Example 28 provided the highest level of UV protection.

[0173] Examples 29 and 30 and Comparative Example 12: Based on the formulations in Table 5-1, solid compositions for Examples 29 and 30 and Comparative Example 12 were prepared.

[0174] Since the obtained compositions were solids, it was impossible to observe the state of the oil droplets or dispersion. Therefore, the absorbance peak value at 300 nm was determined in the same manner as in Table 4 above. The results are shown in Table 5-1.

[0175]

[0176] As is clear from the results in Table 5-1, the compositions of Examples 29 and 30 showed a higher peak absorbance at 300 nm compared to Comparative Example 12, indicating improved UV protection. This result suggests that in the compositions of Examples 29 and 30, the dispersion of polar oil containing a UV absorber not only absorbed UV rays but also scattered them. As a result, the UV protection effect was further improved compared to Comparative Example 12. Furthermore, it was found that Example 30 provided the highest level of UV protection.

[0177] Examples 31-39: Based on the formulations in Table 6, liquid compositions of Examples 31-39 were prepared. More specifically, they were prepared by mixing the first oil phase, the second oil phase, and the amphiphilic compound at 25°C.

[0178] For each of the obtained compositions, the dispersion state of the first and second oil phases, the miscibility between the first and second oil phases, the state of the oil droplets, and the stability of the oil droplets (state of the oil droplets after 1 hour) were confirmed using an optical microscope. The results are shown in Table 6.

[0179]

[0180] (Table 6 Notes) *1: In the evaluation of "dispersion state," "A" indicates that the second oil phase is dispersed in the first oil phase as oil droplets, and "B" indicates that the first oil phase is dispersed in the second oil phase as oil droplets. "-" means that the first oil phase and the second oil phase became miscible, and therefore the dispersion state could not be confirmed. *2: In the evaluation of "miscibility," "×" indicates that the first oil phase and the second oil phase are not miscible, and "○" indicates that the first oil phase and the second oil phase are miscible. *3: In the evaluation of "oil droplet state," "○" indicates that the oil droplets are dispersed, and "×" indicates that they are miscible and no oil droplets are formed. *4: In the evaluation of "oil droplet stability," the state of the oil droplets after storage at 25°C and 40% relative humidity for 1 hour is evaluated. If the oil droplets are dispersed, it is indicated as "○"; if a small number of oil droplets have coalesced to form slightly larger droplets but are still dispersed, it is indicated as "○△"; if about half of the oil droplets have coalesced to form larger droplets but are still dispersed, it is indicated as "△"; and if almost all of the oil droplets have coalesced to form a single layer of oil, it is indicated as "×". In the evaluation of oil droplet stability, "○" is the best evaluation result, followed by "○△", "△", and "×" in order of decreasing evaluation. An evaluation of "△" or higher is considered a pass.

[0181] Examples 40-46: Based on the formulations in Table 7, liquid compositions of Examples 40-46 were prepared. More specifically, they were prepared by mixing the first oil phase, the second oil phase, and the amphiphilic compound at 25°C.

[0182] For each of the obtained compositions, the dispersion state of the first and second oil phases, the miscibility between the first and second oil phases, the state of the oil droplets, and the stability of the oil droplets (state of the oil droplets after 1 hour) were confirmed using an optical microscope. The results are shown in Table 6.

[0183]

[0184] (Table 7 Notes) *1: In the evaluation of "dispersion state," "A" indicates that the second oil phase is dispersed in the first oil phase as oil droplets, and "B" indicates that the first oil phase is dispersed in the second oil phase as oil droplets. "-" means that the first oil phase and the second oil phase became miscible, and therefore the dispersion state could not be confirmed. *2: In the evaluation of "mismatch," "×" indicates that the first oil phase and the second oil phase are not miscible, and "○" indicates that the first oil phase and the second oil phase are miscible. *3: In the evaluation of "oil droplet state," "○" indicates that the oil droplets are dispersed, and "×" indicates that they are miscible and no oil droplets are formed. *4: In the evaluation of "oil droplet stability," the state of the oil droplets after storage at 25°C and 40% relative humidity for 1 hour is evaluated. If the oil droplets are dispersed, it is indicated as "○"; if a small number of oil droplets have coalesced to form slightly larger droplets but are still dispersed, it is indicated as "○△"; if about half of the oil droplets have coalesced to form larger droplets but are still dispersed, it is indicated as "△"; and if almost all of the oil droplets have coalesced to form a single layer of oil, it is indicated as "×". In the evaluation of oil droplet stability, "○" is the best evaluation result, followed by "○△", "△", and "×" in order of decreasing evaluation. An evaluation of "△" or higher is considered a pass.

[0185] 《Additional Experiments on Compatibility》 For each of the first oil phases and amphiphilic compounds in Examples 40 to 46, compositions for Examples 40-1 to 46-1 shown in Table 7-1 were prepared using 45% by mass of dimethicone (second oil phase) with different viscosities. The compatibility of each prepared composition was evaluated. In the evaluation of "Compatibility," "×" indicates that the first oil phase and the second oil phase are not compatible, and "○" indicates that the first oil phase and the second oil phase are compatible, as shown in Table 7-1.

[0186]

[0187] As is clear from the compatibility results in Table 7-1, for each polar oil, it was found that as the viscosity of dimethicone generally increases, the first oil phase and the second oil phase tend to become less compatible (i.e., phase separation becomes easier). Furthermore, it was found that when 300 cSt dimethicone was used in combination with various polar oils, the first oil phase and the second oil phase were not compatible (i.e., phase separation occurred).

[0188] Comparative Examples 13 and 14: Based on the formulations in Table 8, liquid compositions of Comparative Examples 13 and 14 were prepared. More specifically, they were prepared by mixing the first oil phase, the second oil phase, and the amphiphilic compound at 25°C.

[0189] However, in all of these compositions, the oil phase became miscible, making it impossible to obtain an oil-in-oil composition.

[0190]

[0191] Examples 47-49 and Comparative Examples 17-20: Based on the formulations in Table 9, liquid compositions for Examples 47-49 and Comparative Examples 17-20 were prepared.

[0192] More specifically, components 5 to 10 were mixed at 25°C, and then components 1 to 4 were mixed to prepare the composition. The partition coefficient K between the second and first oil phases of the hydrocarbon oil. （第２の油相／第１の油相） Based on the evaluation (K （第２の油相／第１の油相） <1) It is possible that the blended hydrocarbon oil was preferentially distributed to the first oil phase.

[0193] For each of the obtained compositions, the compatibility of the first oil phase and the second oil phase was evaluated in the same manner as described above, and the evaluation results are shown in Table 9. Furthermore, microscopic observation revealed that the compounds of Examples 47 to 49 were compositions in an oil-in-water (oil and water) emulsion state.

[0194] Further, each of the obtained compositions was applied to a PMMA plate for artificial skin, that is, a PMMA plate having irregularities corresponding to skin grooves (SPF MASTER (registered trademark) PA01, manufactured by Shiseido Company, Limited), and the absorbance peak value at 300 nm after application was determined. The respective results are shown in Table 9. The absorbance was measured using a spectrophotometer (U-4150 type self-recording spectrophotometer, manufactured by Hitachi, Ltd.).

[0195]

[0197] More specifically, the solid component 7-4 (dextrin palmitate) was heated and dissolved in component 6, and at 25°C, components 2 to 5, component 7-2 (dimethyl distearyl ammonium hectorite), and component 7-3 were mixed, and then the aqueous components (component 1, component 7-0, component 7-1, component 7-5) were mixed and adjusted. The partition coefficient K of the hydrocarbon oil between the second oil phase and the first oil phase （第２の油相／第１の油相） Based on the evaluation results (K （第２の油相／第１の油相） <1), it is considered that the blended hydrocarbon oil was preferentially distributed in the first oil phase.

[0198] For each of the obtained compositions, the compatibility between the first oil phase and the second oil phase was evaluated in the same manner as above. Also, the absorbance peak value at 300 nm was determined in the same manner as above. The respective obtained results are shown in Table 10. The compounds of Examples 50 to 53 were found to be compositions in an oil-in-(oil and water) type emulsion state as a result of microscopic observation.

[0199]

[0200] The details of the other components in Table 10 are as follows: <00,00426>

[0201] 《Examples 54 to 58 and Comparative Examples 23 to 25》 Similar to the case of Table 10 above, based on Table 11, liquid compositions of Examples 54 to 58 and Comparative Examples 23 to 25 were prepared. <,

[0202] For each of the obtained compositions, the compatibility of the first oil phase and the second oil phase was evaluated in the same manner as described above. The absorbance peak value at 300 nm was also determined in the same manner as described above. The results are shown in Table 11. Microscopic observation revealed that the compounds of Examples 54-58 were oil-in-water (oil and water) emulsion compositions.

[0203]

[0204] The details of the other components in Table 11 are as follows:

[0205] Examples 59 and 60: Based on the formulations in Table 12, solid compositions of Examples 59 and 60 were prepared.

[0206] Since the obtained compositions were solids, it was impossible to observe the state of the oil droplets or dispersion. Therefore, the absorbance peak value at 300 nm was determined in the same manner as in Table 4 above. The results are shown in Table 12.
