Abstract
Description
【0001】
【発明の属する技術分野】本発明は、皮膚外用剤に関し、詳しくは、皮膚を紫外線障害に対して細胞修復効果を有すること、及び表皮ターンオーバー調整作用を有する皮膚外用剤に関する。
【0002】
【従来の技術および課題】紫外線等により皮膚内で発生する活性酸素は、皮膚の角質層及び表皮細胞、真皮細胞にダメージを与え、老化の原因の一つとして考えられている。従来、肌の老化を促進する活性酸素や肌の酸化を抑える成分として、ビタミンEやその誘導体、ビタミンCやその誘導体などの配合した皮膚外用剤が試みられている。
【0003】
【発明が解決しようとする課題】しかしながら、従来用いられてきた成分では効果の面で充分ではなく、満足な結果は得られていない。又、近年ではオゾン層の破壊による紫外線量の増大が考えられ、肌にとって有害であり、老化の原因の一つとして知られている活性酸素の対策やそれに伴ってダメージを受けた肌細胞の修復効果、又環境の破壊や変化による肌の乾燥などに対応する化粧品の開発が望まれている。ダメージを受けた皮膚は、ターンオーバーが速くなり、正常なサイクルが乱れて結果として、皮膚のハリや弾力がなくなり、若々しい肌の状態を維持することができなくなる。
【0004】
【課題を解決するための手段】そこで、本発明者らは、上述した課題に鑑み、鋭意研究を重ねた結果、ダイズ抽出物とクルミ及び/又は麦芽及び/又はトウモロコシ種子の抽出物のうち一種又は二種以上を含有することをすることにより、画期的に細胞修復作用が高まり、日常の紫外線により受けた皮膚細胞の損傷を修復させ、又皮膚繊維の損傷を防止し、更に皮膚内の表皮細胞のターンオーバーを正常に保つことを見出し、本発明の完成に至った。そして、若々しい肌を維持するという美肌効果を有する皮膚化粧料の提供を可能とした。
【0005】本発明に用いることができるダイズ抽出物は、マメ科ダイズ属ダイズGlycine max Merrill(Leguminosae)の種子から得られる抽出物であれば特に限定されない。本発明に用いることができるクルミ抽出物は、クルミ科クルミ属の植物であれば特に限定はなく、例えば、オニグルミJuglans mandshurica Maximowicz var.sieboidianaana MakinoやテウチグルミJuglans regia Linne var. sinensis Decandlle等である。本発明に用いることができる麦芽抽出物は、イネ科オオムギ属の植物であれば特に限定はなく、例えばオオムギHordeum vulgara Linne(Gramineae)である。本発明に用いることができるトウモロコシの種子抽出物は、イネ科トウモロコシ属のトウモロコシZea mays L.の種子から得られる抽出物であれば特に限定されない。又、抽出溶媒は特に限定されていないが、水、1,3−ブチレングリコール又はグリセリン等の多価アルコール、エチルアルコール又はイソプロピルアルコール等の低級アルコール類等を用いることでき、単独・もしくは二種以上の混液から抽出することもできる。
【0006】本発明に用いられる植物エキスの配合量は、皮膚化粧料の総量を基準として0.0001〜10.0質量%が好ましく、更に好ましくは、0.01〜10.0質量%である。
【0007】本発明の皮膚化粧料は、例えばクリーム類・乳液類・ローション類・パック類に適用することができる。
【発明の実施の形態】
【0008】
1.
細胞の培養
細胞は人胎児皮膚ケラチノサイトを用い、培地は大日本製薬株式会社のDMEM培地に牛胎児血清(以下FBSと記す。)を15%になるように添加した培地を用いた。直径8cmのシャーレに人皮膚ケラチノサイト細胞をコンフルエントになるまで培養した。コンフルエントになった細胞を24wellプレートに継代し、培地0.5mlで1日から3日培養し、UV−Bを150mJ/cm2照射した。その後、各種抽出液を添加したFBS5%のDMEM培地10mlで48時間培養し、培養液の細胞増殖度を測定し、UVダメージからの修復効果を調べた。植物抽出物を単独で添加する際は系内濃度が100ppm、組み合わせて添加する際は、ダイズ抽出物とその他の植物抽出物の系内濃度をそれぞれ50ppmずつとした。2.
細胞増殖度の測定
細胞増殖度の測定は、24wellプレートで48時間培養した培養液にCell Counting Kit(同仁)を50μl添加し、よく混和した。呈色反応時間は2時間とした。反応後、96wellプレートに培養液を100μlづつ移し、プレートリーダーで測定した。リン酸緩衝液(蒸留水1リットル当たりに、NaCl:0.8g,KCl:0.2g,KH2PO4:0.2g,Na2HPO4・12H2O:2.9gに調整した緩衝液で、以下PBSと記す。)を試料と同体積量添加したものをコントロールとして細胞修復率(%)を算出した。
修復率(%)={(UV照射後の試料添加の48時間培養後の細胞増殖度−UV照射試料無添加の48時間培養後の細胞増殖度)/(UV未照射試料無添加の48時間培養後の細胞増殖度−UV照射試料無添加の48時間培養後の細胞増殖度)}×100
【0009】表1、及び表2に測定結果から求めた細胞修復率(%)を示す。表1、及び表2に示したように、クルミ、麦芽、及びトウモロコシの種子の抽出物は、単独では高い細胞修復効果があるとは言えないが、ダイズ抽出物と組み合わせることにより、何れも高い細胞修復効果を示した。

The present invention relates to an external preparation for skin, and more particularly, to an external preparation for skin having a cell repair effect against ultraviolet damage and an epidermal turnover regulating action.
[0002]
2. Description of the Related Art Active oxygen generated in the skin due to ultraviolet rays or the like damages the stratum corneum, epidermal cells and dermal cells of the skin, and is considered as one of the causes of aging. BACKGROUND ART Conventionally, skin external preparations containing vitamin E and its derivatives, vitamin C and its derivatives, etc. have been tried as active oxygen that promotes skin aging and as a component that suppresses skin oxidation.
[0003]
However, the conventionally used components are not sufficient in terms of effect, and satisfactory results have not been obtained. In recent years, an increase in the amount of ultraviolet rays due to the destruction of the ozone layer is considered, which is harmful to the skin and measures against active oxygen, which is known as one of the causes of aging, and repairs damaged skin cells. There is a demand for the development of cosmetics that respond to the effects and the dryness of the skin due to destruction or change in the environment. Damaged skin has a faster turnover and disrupts normal cycles, resulting in a lack of firmness and elasticity of the skin and a failure to maintain a youthful skin condition.

BEST MODE FOR CARRYING OUT THE INVENTION
[0008]
1.
Human fetal skin keratinocytes were used as cell culture cells, and a medium obtained by adding fetal bovine serum (hereinafter referred to as FBS) to DMEM medium of Dainippon Pharmaceutical Co., Ltd. to a concentration of 15% was used. Human skin keratinocyte cells were cultured in a petri dish having a diameter of 8 cm until they became confluent. The confluent cells were subcultured on a 24-well plate, cultured in 0.5 ml of a medium for 1 to 3 days, and irradiated with UV-B at 150 mJ / cm 2 . Thereafter, the cells were cultured for 48 hours in 10 ml of a 5% FBS DMEM medium to which various extracts were added, and the degree of cell proliferation of the culture was measured to examine the effect of repair from UV damage. When the plant extract was added alone, the concentration in the system was 100 ppm, and when combined, the soybean extract and the other plant extract were each 50 ppm in the system. 2.
Measurement of Cell Proliferation Degree The cell proliferation degree was measured by adding 50 μl of Cell Counting Kit (Dojin) to a culture solution cultured for 48 hours on a 24-well plate, and mixed well. The color reaction time was 2 hours. After the reaction, 100 μl of the culture solution was transferred to a 96-well plate at a time, and measured with a plate reader. Per phosphate buffer (1 liter of distilled water, NaCl: 0.8g, KCl: 0.2g , KH 2 PO 4: 0.2g, Na 2 HPO 4 · 12H 2 O: buffer adjusted to 2.9g The cell repair rate (%) was calculated using a sample to which the same volume as the sample was added as a control.
Repair rate (%) = {(cell proliferation after culture for 48 hours after addition of sample after UV irradiation−cell proliferation after culture for 48 hours without addition of UV irradiation sample) / (48 hours without addition of sample without UV irradiation) Degree of cell proliferation after culturing-Degree of cell proliferation after culturing for 48 hours without addition of UV irradiation sample)} × 100
Tables 1 and 2 show the cell repair rates (%) determined from the measurement results. As shown in Tables 1 and 2, walnut, malt, and corn seed extracts cannot be said to have a high cell repair effect by themselves, but are all high when combined with a soybean extract. A cell repair effect was shown.

[0021]
The present invention will be described below in detail based on examples and comparative examples. The test for measuring the turnover of the stratum corneum used in the present invention is as follows.
[0022]
[Stratum corneum turnover measurement test]
Ultraviolet rays were applied to the forearms of 10 subjects. Three days after the first UV irradiation, an ointment containing 5% by weight of a fluorescent dye, dansyl chloride, was prepared in white petrolatum, and was occlusively applied to the skin of the subject's UV-irradiated forearm for 24 hours. Dansyl chloride was permeated. From the 5th day after irradiation with ultraviolet light, apply about 0.2 g of the test sample twice a day (morning / ta), and examine the fluorescence of dansyl chloride once a day in a dark place using an ultraviolet lamp. The number of days until a one-step decrease was defined as the number of skin stratum corneum turnovers. Normal skin stratum corneum turnover is 13 to 15 days, but in tanned skin it can be as short as about 10 days. On the other hand, when the cell repair effect is observed, the turnover recovers even in the tanned skin up to 13 to 15 days.
Table 3 shows Comparative Examples 1 to 5, Table 4 shows Examples 1 to 5, and Table 5 shows Examples 6 to 10. Further, the production methods of the lotions of Comparative Examples and Examples described in Tables 3 to 5 were prepared according to a conventional method. In addition, the turnover measurement test result of the stratum corneum was also described in Tables 3-5. Then, although not described in Tables 3 and 4, the number of turnovers was measured as a comparison in the case of non-irradiation with ultraviolet light.
[0024]
[Table 3]
[0025]
[Table 4]
[0026]
[Table 5]
The cosmetics of Comparative Example 1 containing no active ingredient, the cosmetics of Comparative Examples 2, 3 and 4 containing solely the walnut / malt / corn extract, and the soybean extract of Comparative Example 4 were used alone. For the cosmetic liquid of Comparative Example 5, the number of turnovers (about 10 days) was about the same as that of ultraviolet irradiation. In addition, when applying the cosmetics of Examples 1 to 10 in which the soybean extract and the walnut / malt / corn seed extract were combined, approximately the same as the non-irradiation of ultraviolet light which is the normal skin turnover number. Turnover number (around 14 days). This indicates that the cell repairing effect component of the present invention has a high effect of recovering from damage caused by ultraviolet light, and is excellent in turnover regulating effect. In addition, the same excellent effect was obtained with the cosmetic liquid of Example 10 in which two or more plant extracts including walnut, malt, and corn seeds were combined with a soybean extract.
[0027]
As described above, it is apparent that the present invention can provide a skin cosmetic which has an excellent cell repairing effect and is effective in controlling turnover disturbed by damage of ultraviolet rays.
