Description

[[Technical Field]]

[0001] The present invention relates to a cosmetic composition. [[Background Art]]

[0002] Protecting the skin from ultraviolet rays is one of the important issues for skin care and body care. It is well known that not only medium-wavelength ultraviolet rays (UVB region: wavelength 290 to 320 nm), which are known to cause sunburn and inflammation, but also long-wavelength ultraviolet rays (UVA region: wavelength 320 to 400 nm) have effects on the skin such as photoaging.

[0003] Conventional cosmetics for ultraviolet protection generally and often contain 2-ethylhexyl p-methoxycinnamate as an ultraviolet absorber. While 2-ethylhexyl p-methoxycinnamate has an ultraviolet absorbing effect in the UVB region, there is a need for an ultraviolet absorber with better ultraviolet absorbing capacity in the UVA region.

[0004] In contrast, the ultraviolet absorber disclosed in Patent Document 1 has absorption capacity in both the UVA region and the UVB region, exhibits an ultraviolet blocking effect over a wide range of wavelengths, and has a previously unobserved property that the ultraviolet absorption capacity in the UVA and UVB regions increases as the duration of ultraviolet irradiation progresses.

[0005] More specifically, the ultraviolet absorber of Patent Document 1 is represented by general formula I: [[Chemical Drawing]] wherein -OA represents an alkoxy group, which contains the compound represented by the formula as an active ingredient. [[Prior Art Documents]] [[Patent Documents]]

[0006] [[Patent Document 1]] International Publication No. 2009 / 041098 [[Summary of the Invention]] [Problems that the invention aims to solve]

[0007] In Patent Document 1, the ultraviolet absorption capacity of the compound represented by the above general formula I was investigated by incorporating it into an ointment in its original state. As a result, it was found that the ultraviolet absorption capacity in the UVA and UVB regions of the ointment containing the compound represented by general formula I increased with increasing ultraviolet irradiation time.

[0008] However, when the compound represented by the above general formula I was incorporated into sunscreen lotion and its UV absorption capacity was investigated, its UV absorption capacity did not decrease with increasing exposure time, but no significant increase was observed either.

[0009] The present invention aims to improve the above circumstances, and its objective is to provide a cosmetic composition in which the ultraviolet or sunlight exposure time is increased and the ultraviolet absorption capacity in at least the UVA region is significantly improved.

[0010] In this invention, the degree to which the effect of improving ultraviolet absorption capacity in at least one of the UVA and UVB regions by ultraviolet irradiation or sunlight irradiation is increased can be evaluated by the ratio of the ultraviolet absorbance after irradiation to the ultraviolet absorbance before irradiation (ultraviolet absorbance after irradiation / ultraviolet absorbance before irradiation). [Means for solving the problem]

[Effects of the Invention]

[0013] According to the present invention, it is possible to provide a cosmetic composition in which the effect of improving ultraviolet absorption capacity in at least the UVA region is enhanced by ultraviolet irradiation or sunlight irradiation. [Modes for carrying out the invention]

[0014] Hereinafter, embodiments of the present invention will be described in detail. It should be noted that the present invention is not limited to the following embodiments, and can be implemented with various modifications within the scope of the spirit of the invention.

[0015] <<Cosmetic Composition>> The cosmetic composition of the present invention (hereinafter sometimes simply referred to as "the composition of the present invention") is a cosmetic composition comprising a polar oil and Compound I having a structure represented by the following formula (I),

Chemical Formula

[0016] The present inventors have found that by blending the polar oil and Compound I in the composition at a specific composition ratio, the effect of improving the ultraviolet absorption ability caused by ultraviolet irradiation or sunlight irradiation can be further increased at least in the UVA region.

[0053] The compound used as compound I is the one shown in the following structural formula: [ka]

[0054] Evaluation of the effect of improving UV absorption capacity through UV irradiation or sunlight irradiation. Samples of each of the prepared examples and comparative examples were spread onto PMMA plates and irradiated with simulated sunlight using a device that emits simulated sunlight (Suntest XLS+ device manufactured by ATLAS Corporation) (hereinafter referred to as "Suntest"). Specifically, the Suntest was performed under the following conditions. Irradiation time: 2 hours Surface temperature: 50℃ Irradiation output: 3860KJ / m 2

[0055] The ultraviolet absorption wavelengths of the samples before and after the sun test were measured.

[0056] Changes were observed in the ultraviolet absorption wavelengths of the samples in each example and comparative example before and after SunTest. The absorbance of each sample before and after irradiation at 360 nm (UVA region) was then calculated as the improvement rate of ultraviolet absorption capacity due to sunlight irradiation (hereinafter also simply referred to as the "improvement rate") according to the following formula: Improvement rate = (Absorbance after irradiation / Absorbance before irradiation) × 100%

[0057] Furthermore, the improvement rate of Comparative Example 1 was set as "1 (baseline)," and the ratio of the improvement rates of each example was calculated as the "relative improvement rate" (improvement rate of each example / improvement rate of Comparative Example 1). The results are shown in Tables 1 and 2.

[0058] Furthermore, for each example and comparative example sample, we checked for an increase in absorption in the UVA region (wavelength 320-400 nm) of ultraviolet absorption wavelengths after the sun test. Similarly, we checked for an increase in absorption in the UVB region (wavelength 290-320 nm) of ultraviolet absorption wavelengths after the sun test. The results are shown in Tables 1 and 2.

[0059] [Table 1]

[0060] [Table 2]

[0061] As is clear from the results in Tables 1 and 2, all of the compositions in Examples 1 to 12 showed an increased effect in improving ultraviolet absorption capacity, at least in the UVA region, compared to Comparative Example 1.
