Description

[Technical field]

[0001] The present invention relates to an oily gel composition. [Background technology]

[0002] Conventionally, in products such as oil-based cosmetics, it has been desired to achieve both shape retention during storage and spreadability during use, and for example, oil-based gel compositions using organically modified clay minerals have been investigated. For example, Patent Document 1 describes that an oil-based gel composition containing an organically modified clay mineral having a plate-like particle structure, a nonionic surfactant, and an oil exhibits a thickening gel effect, and can provide a water-in-oil emulsion composition that has low viscosity and high emulsion stability. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2008-63331 A Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional oil-based gel compositions containing organically modified clay minerals, when octyl paramethoxycinnamate is used in combination, there are problems in that application and usability deteriorate, and oil seepage occurs due to a decrease in viscosity. [Means for solving the problem]

[0005] The present inventors have discovered that an oil-based gel composition, which is a combination of an organic modified clay mineral, octyl paramethoxycinnamate, a specific modified silicone, a liquid non-volatile oil, and a small amount of water, a lower alcohol, and a polyol, is in a gel state with no fluidity when left to stand, but when physical force such as stirring (shaking) is applied, the fluidity is improved, the composition spreads while maintaining its thickness, and a thick oily film feeling is obtained on the skin.When left to stand, the composition returns to a gel with no fluidity, so that the gel can be prevented from dripping even if the container is turned over during storage, and oil separation is suppressed, making the composition highly stable.

[0006] The present invention comprises the following components (A), (B), (C), (D) and (E): (A) Organically modified clay minerals, (B) octyl paramethoxycinnamate, (C) a modified silicone having an alkyl group having 12 or more carbon atoms and a polyoxyalkylene group or a polyglyceryl group, (D) a non-volatile oil that is liquid at 25°C other than component (B), (E) One or more selected from water, lower alcohols and polyols, 1% by mass or less The present invention relates to an oily gel composition comprising the above compound. Effect of the Invention

[0007] The oily gel composition of the present invention is in a gel state with no fluidity when left to stand, but when physical force such as stirring (shaking) is applied, the fluidity is improved and it becomes easy to take, and when left to stand, it returns to a gel with no fluidity, so that the gel can be prevented from dripping even if the container is turned over during storage. In addition, when applied to the skin after shaking with a physical force, it spreads while maintaining its thickness, and a thick oily film feeling is obtained on the skin. Furthermore, oil separation is suppressed, and the stability is excellent. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0058] [Table 2]

[0059] From the results in Table 2, it was confirmed that the oily gel compositions of the Examples had larger storage modulus (G') [Pa] values ​​than the Comparative Examples, and became harder gels when left at rest.

[0060] Examples 13 to 16 In the same manner as in Examples 1 to 12, oily gel compositions (foundations) having the compositions shown in Table 3 were produced, and the properties one hour after filling the container, the fluidity immediately after shaking, the properties one hour after shaking, the spreadability while maintaining the thickness, the thick oily film feeling on the skin, and the stability after 7 days were evaluated. The results are also shown in Table 3.

[0061] [Table 3]

[0062] Example 17 Oily gel compositions (foundations) having the compositions shown in Table 4 were produced in the same manner as in Examples 1 to 12. The obtained oily compositions suppress the settling of pigments when left to stand, and when applied to the skin after being shaken by physical force, they spread while maintaining their thickness, providing a thick oily film feeling on the skin.
