Description
【0001】
【発明の属する技術分野】
本発明は、ヨクイニンから水にて抽出したエキスを水蒸気蒸留して得られた液体を有効成分とする美白剤又は肌あれ防止剤、及びこれを含有する皮膚外用剤に関する。更には他の特定の薬効剤とを組み合わせて含有することにより、より優れた美白効果、肌あれ防止効果を有する皮膚外用剤に関する。
【0002】
【従来の技術】
従来より、乳液、クリーム、化粧水、パック、洗浄料、分散液、軟膏、液剤、エアゾール、貼付剤、パップ剤、リニメント剤等の皮膚外用剤には、これらに所定の薬効を付与することを目的として薬効剤が加えられている。そして、日常的に浴びる紫外線や乾燥などにより生じる皮膚のしみやくすみ、肌あれを予防あるいは改善するために、例えばビタミンCやアロエ抽出物等が加えられている。
しかしながら、これらの薬効剤は、目的の効果を得ようとして製剤に多量に配合すると、変色したり変質するなど製剤に悪影響を与えたり、あるいは所期の薬効が得られない場合があり、その改善が望まれていた。
【0003】
【発明が解決しようとする課題】
本発明は、上記の事情に鑑みなされたもので、製剤中に多量に配合しても経時的に安定であり、製剤の外観等にも悪影響を与えずに使用することができ、美白効果又は肌あれ防止効果が高く発揮できる美白剤又は肌あれ防止剤を提供することを目的とする。また、この美白剤、肌あれ防止剤を含有する皮膚外用剤を提供することを目的とする。ここで言う美白効果には、紫外線などの外的な環境因子、あるいはホルモンバランスの変調、加齢などの内的因子によって生じる皮膚のくすみ、しみを改善、あるいは防御する効果が含まれる。
【0004】
【課題を解決するための手段】
本発明者等は、従来の製剤中の水と同様に、多量に配合しても経時的に安定で、製剤の外観等に悪影響を与えずに使用することができ、かつ効果を高く発揮することが可能な薬効剤について鋭意検討した結果、ヨクイニンから水にて抽出したエキスを水蒸気蒸留して得られた液体(以下、この液体をヨクイニン水と言うことがある)が美白効果を有し、又肌あれ防止剤としても優れたものであることを見出した。更に、このような効果を有するヨクイニン水は、皮膚外用剤中に用いられる従来の精製水と同様に使用することが可能な上、他の薬効剤と組み合わせることにより、皮膚外用剤としてより優れた美白、及び肌あれ防止効果が得られることを見出し、本発明を完成した。
【0005】
すなわち本発明は、ヨクイニンから水にて抽出したエキスを水蒸気蒸留して得られた液体を有効成分とする美白剤である。また、本発明は、ヨクイニン水を有効成分とする肌あれ防止剤である。更に本発明は、この美白剤又は肌あれ防止剤を含有することを特徴とする皮膚外用剤である。
【0006】
そして、更に、本発明は、次の成分(A)及び(B)
(A)ヨクイニン水
(B)アスコルビン酸及びその誘導体並びにそれらの塩から選ばれる一種又は二種以上、
を配合することを特徴とする皮膚外用剤である。
また、本発明は、次の成分(A)及び(B)
(A)ヨクイニン水
(B)グリチルリチン酸及びその誘導体並びにそれらの塩から選ばれる一種又は二種以上、
を配合することを特徴とする皮膚外用剤である。
また更に、本発明は、次の成分(A)、(B)及び(C)
(A)ヨクイニン水
(B)アスコルビン酸及びその誘導体並びにそれらの塩、又はグリチルリチン酸及びその誘導体並びにそれらの塩から選ばれる一種又は二種以上
(C)トウキ抽出液、センキュウ抽出液、センプクカ抽出液、ボタン抽出液、ハマメリス抽出液、冬虫夏草抽出液、メロスリア抽出液、ビタミンE及びその誘導体並びにそれらの塩、小麦胚芽油から選ばれる一種又は二種以上
を含有することを特徴とする皮膚外用剤である。
【0007】
【発明の実施の形態】
本発明に用いられるヨクイニンは、イネ科ジュズダマ属ジュズダマ(Coixlachryma−jobi L.)、又はイネ科ジュズダマ属ハトムギ(Coix lachryma−jobi L.var.ma−yuen(Romam))の種仁であり、それらの産地は特に限定されない。
【0008】
本発明のヨクイニン水としてハトムギの種仁が好ましく用いられるが、ハトムギ(Coix lachryma−jobi L.var.ma−yuen(Romam))は、中国、インドシナ原産で日本に古くから渡来し、西南部の暖地で栽培される一年草で、鎮痛、消炎、排膿効果のある生薬として用いられてきた。
【0009】
ヨクイニン水は、ヨクイニンから水にて抽出したエキスを水蒸気蒸留して得られる水性画分であり、抽出までの過程で必要に応じて圧力や熱を加えても良い。また、抽出して得た液を必要に応じて精製、あるいはろ過、脱臭脱色処理等を施した後、水蒸気蒸留を行なっても良い。得られたヨクイニン水はリノール酸を含有する。リノール酸が確認される範囲内において、更に得られた水蒸気蒸留物を必要に応じてろ過や濃縮、あるいは加水してもよい。
【0010】
本発明のヨクイニン水を有効成分とする美白剤又は肌あれ防止剤は、常法に従い通常の皮膚外用剤に使用される種々の形態の基剤に配合し、製剤化することにより皮膚外用剤を得ることができる。本発明の美白剤又は肌あれ防止剤の有効成分であるヨクイニン水の皮膚外用剤中における含有量は0.1質量%(以下単に「%」で示す)以上が好ましい。含有量が0.1%以上であれば、本発明で目的とする美白効果、肌あれ防止効果を発揮することができる。本発明の美白剤又は肌あれ防止剤の有効成分であるヨクイニン水は、各種形態の皮膚外用剤において精製水や常水の代わりに用いることもできる。その場合には、ヨクイニン水は水としての役割を発揮しつつ、美白効果、肌あれ防止効果を発揮する。また、本発明の美白剤又は肌あれ防止剤は、更に他の特定の薬効剤と組み合わせることにより、より美白効果、肌あれ防止効果の優れた皮膚外用剤が得られる。
【0011】

参考例1 ヨクイニン水の製造
ハトムギの種皮を除いた種子(ヨクイニン)100gに、精製水1Lを加え、3時間加温抽出した後ろ過し、ろ過したろ液を水蒸気蒸留装置にいれ、得られた留液の水溶性画分をろ過してヨクイニン水1Kgを得た。得られたヨクイニン水よりリノール酸の確認は薄層クロマトグラフィーにて行なった。
【0025】
参考例2 アロエ抽出物の製造
ユリ科ケープアロエ(Aloe ferox Mill.)の葉100gに、25vol%含水エチルアルコール100Lを加え、室温にて3日間抽出を行った後濾過してアロエ抽出物80Lを得た。
【0026】
試験例1 細胞培養によるメラニン生成抑制及び細胞生存率試験
マウス由来のB16メラノーマ培養細胞を使用した。2枚の6穴プレートに10%FBS含有MEM培地を適量とり、B16メラノーマ細胞を播種し、37℃、二酸化炭素濃度5vol%中にて静置した。翌日、参考例1で得たヨクイニン水を最終濃度が0(対照)、500、5000、50000μg/mLとなるように検体調製液を添加し混和した。培養5日目に培地を交換し、再度検体調製液を添加した。翌日、培地を除き、1枚のシャーレについて、細胞をリン酸緩衝液(pH7)にて洗浄した後回収し、B16メラノーマ培養細胞の白色化度を以下の判定基準にて評価した。
又、比較例として既にメラニン生成抑制作用のあることが知られている参考例2で得たアロエ抽出物についても同様の試験を行った。
【0027】
(判定基準)
+:対照に対してあきらかに白色である。
±:対照に対してやや白色である。
−:対照と同じ黒色である。
【0028】
残りの1枚のプレートについて、細胞をホルマリン固定後、1%クリスタルバイオレット溶液を添加し染色した。各検体濃度に対する細胞生存率をモノセレーター(オリンパス社製)で測定した。以上の結果を表1に示す。

Reference Example 2 Production of Aloe Extract To 100 g of leaves of Aloe ferox Mill., 100 L of 25 vol% hydrous ethyl alcohol was added, extracted at room temperature for 3 days, filtered, and then 80 L of Aloe extract was obtained. Obtained.
[0026]
Test Example 1 Inhibition of melanin production by cell culture and cell viability test B16 melanoma cultured cells derived from mice were used. An appropriate amount of 10% FBS-containing MEM medium was taken in two 6-well plates, seeded with B16 melanoma cells, and allowed to stand at 37 ° C. in a carbon dioxide concentration of 5 vol%. On the next day, the sample preparation solution was added and mixed with the Yokuinin water obtained in Reference Example 1 so that the final concentrations were 0 (control), 500, 5000, and 50000 μg / mL. On day 5 of the culture, the medium was changed, and the sample preparation solution was added again. On the next day, the medium was removed and the cells were collected after washing with a phosphate buffer (pH 7) for one petri dish, and the degree of whitening of the cultured B16 melanoma cells was evaluated according to the following criteria.
Moreover, the same test was done also about the aloe extract obtained in the reference example 2 already known to have a melanin production inhibitory effect as a comparative example.
[0027]
(Criteria)
+: Clearly white relative to the control.
±: Slightly white with respect to the control.
-: The same black color as the control.
[0028]
The remaining one plate was stained with formalin-fixed cells after adding 1% crystal violet solution. The cell viability for each sample concentration was measured with a monocerator (Olympus). The results are shown in Table 1.
[0029]
[Table 1]
[0030]
As is apparent from the results in Table 1, Yokuinin water has a higher ability to suppress the production of melanin than the aloe extract, which is known to have a whitening effect and a prevention / improving effect on skin, and B16 melanoma cultured cells. Was found to be less toxic. Therefore, Yokuinin water, when applied to the skin, exerts an excellent melanin production inhibitory effect, suppresses skin blackening due to sunburn, spots, freckles, etc., and has a whitening effect, prevention of skin roughness, and improvement effect. It is thought that it can be obtained.

Example 1 ( reference products 1 to 3, inventive products 4 to 6 and 8 to 12 , comparative products 1 to 12): Cream Table 2 ( reference products 1 to 3, inventive products 4 to 6 and 8 to 12 ), A cream having the composition shown in Table 3 (Comparative products 1 to 12) was prepared and combined with the Yokuinin water of the present invention, and this Yokuinin water and the medicinal agent of the component (B) or (C) of the present invention were combined. The whitening effect and the anti-skin effect were investigated. The results are also shown in Table 2.
