Particularly preferred oily liquid media include ethylhexyl salicylate and ethylhexyl methoxycinnamate. The preferred amount of oily liquid medium, in relation to the aqueous liquid medium described below, is such that the mass ratio of oily liquid medium / (aqueous liquid medium+oily liquid medium) is in the range of 0.1 to 0.9, more preferably 0.3 to 0.7. In the present invention, the "oil-based liquid medium" may be an oil component that is solid at room temperature (20°C) by itself, as long as it dissolves in other coexisting oil-based liquid media and is liquid as a whole.

[0010] [Aqueous liquid medium] In the present invention, an aqueous liquid medium refers to an organic liquid medium other than water, which forms a homogeneous phase when mixed with water in a 1:1 ratio, and also forms a homogeneous phase when mixed with the oily liquid medium. Specific examples include dipropylene glycol, polyethylene glycol (for example, PEG-8) that is liquid at room temperature, alkylene oxide derivatives, 1,2-hexanediol, isopropylene glycol, propylene glycol, and 1,3-butylene glycol. More preferred are dipropylene glycol, polyethylene glycol (for example, PEG-8) which is liquid at room temperature, alkylene oxide derivatives, and 1,2-hexanediol. Some examples may include 1,3-propanediol, diglycerin, dynamite glycerin. Particularly preferred are dipropylene glycol and polyethylene glycol which is liquid at room temperature.

[0011] [Water-based solidifying agent] In the present invention, the aqueous solidifying agent that is particularly preferably used is soluble in the aqueous liquid medium and has a solidifying function. Specific examples include bis(polyethylene glycol methyl ether dimethyl silane), polyethylene glycols that are solid at 25°C (e.g., polyethylene glycol-400), and polyethylene glycol-decyltetradeceth-20-hexamethylene diisocyanate copolymers.

[0012] [Oil-based solidifying agent] Although not an essential component, a small amount of an oil-based solidifying agent can be added to the present invention. Examples of oily solidifying agents that can be suitably used in the present invention include 12-hydroxystearic acid and dibutyl lauroyl glutamide.

[0013] [Amount of each ingredient] In the present invention, the total amount of the aqueous liquid medium, oily liquid medium, and aqueous solidifying agent is preferably 90% by mass or more of the composition excluding powder. If the essential components are less than 90% by mass of the composition excluding the powder, the solidification property may be reduced. Here, the powder also includes porous powders carrying oily components and aqueous components. Since these powders do not affect the affinity of the aqueous liquid medium and oily liquid medium, they can be considered as being excluded from the system, including the carried oily and aqueous components. In the present invention, the mass ratio of oily liquid medium to (aqueous liquid medium + oily liquid medium) is preferably 0.1 to 0.9, more preferably 0.3 to 0.7. If the mass ratio of the oily liquid medium is less than 0.3, the properties of the oily composition are difficult to exhibit. If it exceeds 0.7, the proportion of the aqueous liquid medium decreases relatively, and solidification tends to deteriorate.

[0037] Preferred embodiments of the solid oily composition of the present invention will be described below. First, the inventors investigated aqueous liquid media that are compatible with oily liquid media in order to solidify the oily liquid media with an aqueous solidifying agent. The results are shown in Table 1. The evaluation of the solidification property was carried out visually, and the hardness was measured using a rheometer by reading the range when a probe with a diameter of 5.6 mm was inserted 2 mm at a speed of 20 mm / min. The hardness of the solid oily composition of the present invention is preferably 10-500, and more preferably 20-250.

[0038] [Table 1]

[0039] As shown in Table 1, first, ethylhexyl methoxycinnamate, a relatively highly polar oil, was used as the oil-based liquid medium, and an aqueous liquid medium compatible with ethylhexyl methoxycinnamate in a mass ratio of 1:1 was selected. As a result, dipropylene glycol (Test Example 1-1) and polyethylene glycol 400 (Test Example 1-2) were miscible with the ethylhexyl methoxycinnamate in a mass ratio of 1:1, but glycerin, propanediol, and diglycerol (Test Examples 1-3 to 1-5) were not miscible and separated. Furthermore, when polyethylene glycol-400 was added as an aqueous solidifying agent to attempt solidification, gelation of the entire system was observed in Test Examples 1-1 and 1-2.

[0040] Next, the inventors investigated oily liquid media, and the results are shown in Table 2.

[0041] [Table 2]

[0042] As shown in Table 2, ethylhexyl salicylate formed a homogeneous phase when combined with dipropylene glycol (Test Example 2-1), but did not show good compatibility with PEG-8 (Test Example 2-2). Furthermore, silicone oil, isopropyl myristate, and phenyl silicone, which have low polarity, did not show good compatibility with either DPG or PEG-8 (Test Examples 2-3 to 2-5).

[0043] Next, the inventors investigated solidifying agents, and the results are shown in Table 3.

[0044] [Table 3]

[0045] As shown in Table 3, a mixed medium of ethylhexyl methoxycinnamate and ethylhexyl salicylate was used as the oil medium, and a mixed medium of DPG and PEG-8 was used as the aqueous medium, and both showed good compatibility. The aqueous solidifying agents PEG-400, bisPEG-18 methyl ether dimethyl silane, and PEG-240·decyltetradeceth-20·hexamethylene diisocyanate copolymer had gelling ability in aqueous / oil-based mixed systems, but the oil-based solidifying agent 12-hydroxystearic acid alone showed only very weak solidifying ability.

[0046] Furthermore, the inventors investigated the polarity of the solidifying agent and its solidifying ability. The results are shown in Table 4.

[0047] [Table 4]

[0048] As is clear from Table 4, the aqueous solidifying agent PEG-400 and the oil-based solidifying agents 12-hydroxystearic acid and dibutyl lauroyl glutamide had the gelling ability for aqueous / oil-based mixed systems, but the aqueous solidifying agent Adekanol only had a weak solidifying ability, and the highly polar aqueous solidifying agent gellan gum (a sugar derivative) and the less polar oil-based solidifying agents dextrin palmitate and microcrystalline wax had no solidifying ability.

[0049] Furthermore, the inventors used ethylhexyl methoxycinnamate, a relatively highly polar oil, as an oil-based liquid medium to select aqueous liquid media that are compatible with ethylhexyl methoxycinnamate at a mass ratio of 1:1. The results are shown in Table 5.

[0050] [Table 5]

[0051] As is clear from Table 5, dipropylene glycol (DPG), polyethylene glycols (PG; PEG-6, PEG-8) which are liquid at room temperature, 1,2-hexanediol (1,2-HD), and alkylene oxide derivatives (PEG / PPG-14 / 7 dimethyl ether, PEG / PPG-9 / 2 dimethyl ether, PEG / PPG-36 / 41 dimethyl ether, PEG / PPG-55 / 28 dimethyl ether, PEG / PPG-17 / 4 dimethyl ether) are superior aqueous liquid media to oil-based liquid media (ethylhexyl methoxycinnamate; MCX).

[0052] Furthermore, the present inventors have selected aqueous liquid media that are compatible with ethylhexyl methoxycinnamate at various mass ratios. The results of this investigation are shown in Table 6.

[0053] [Table 6]

[0054] As is clear from Table 6, the good solvents that showed high compatibility in Table 5 were compatible with the oil-based liquid medium at any mass ratio. In contrast, the highly hydrophilic solvents isopropylene glycol (IPG), propylene glycol (PG), and 1,3-butylene glycol became compatible by changing the ratio, but the extremely hydrophilic solvents 1,3-propanediol (1,3-PD), diglycerin (DG), and dynamite glycerin (DDG) were not compatible even when the ratio was changed.

[0055] The present inventors also investigated the behavior of aqueous liquid media that are unlikely or unable to function alone as solvents for oily liquid media, specifically 1,3-butylene glycol (1,3-BG), diglycerin (DG), 1,3-propanediol (1,3-PD), propylene glycol (PG), isopropylene glycol (IPG), and dynamite glycerin (DDG), in the presence of dipropylene glycol, a good solvent. The results are shown in Table 7.

[0056] [Table 7]

[0057] Table 7 above shows that even for aqueous liquid media with low affinity to oily liquid media, the compatibility with the oily liquid medium is improved by coexistence with an aqueous liquid medium with high affinity (dipropylene glycol), and it can also be seen that 1,3-propanediol (1,3-PD), diglycerin (PG), and dynamite glycerin (DDG) are also compatible depending on the proportions at which they coexist as aqueous liquid solvents.

[0058] The present inventors further investigated the ethylhexyl methoxycinnamate:DPG ratio of 1:2, which showed improved compatibility in Table 6. The results are shown in Table 8.

[0059] [Table 8]

[0060] From Table 8, it was found that compatibility with the aqueous medium was improved by including an oil-based liquid medium:aqueous liquid medium with high affinity=1:2. In Table 6, 1,3-propanediol, diglycerin, and dynamite glycerin, which were not compatible at any concentration, were compatible when mixed with ethylhexyl methoxycinnamate:DPG at a ratio of 1:2, depending on the concentration.

[0061] The present inventors have investigated the state of a solid composition when an oil-absorbing powder is contained therein. The results are shown in Table 9. The smoothness and stability were evaluated as follows. [Method of evaluating smoothness] A panel of 10 experts applied the solid compositions to their skin and evaluated them based on the number of people who felt a smooth sensation. ◎: More than 8 out of 10 people felt smoothness 〇: 7 out of 10 people felt smoothness 〇△: 6 out of 10 people felt smoothness △: 4-5 out of 10 people felt smoothness ×: Fewer than 3 out of 10 people felt smoothness [Stability evaluation method] The test was visually inspected at 25°C and 50% humidity to see if any separation or lumps had occurred. 〇: No separation or lumps have occurred ×: Separation or lumps have occurred

[0062] [Table 9]

[0063] As can be seen from Table 9, when oil-absorbing powder is added, smoothness tends to improve, but it is preferable that the total amount of liquid is slightly higher (55% by mass or more).
