【発明の属する技術分野】
本発明は、シラン抽出物と、特定の植物及び菌類抽出物を組み合わせて用いることにより、皮膚になじみやすく、高い皮膚保湿効果,美肌効果及び肌荒れ改善効果を発揮し得る皮膚外用剤に関する。
【0002】
【従来の技術】
従来、薬用植物をはじめとする多種類の植物の抽出物が皮膚外用剤に用いられてきた(例えば、非特許文献1,非特許文献2等)。近年、自然志向及び動物愛護による植物志向の高まりを受けて、ますます植物や菌類抽出物に有効成分を求める傾向が高まっている。
【0003】
しかし植物や菌類の抽出物は、それぞれが多様な作用を有するものの、総じてその作用はさほど強くないことが多く、皮膚外用剤において、期待する作用効果の生じる量の植物や菌類抽出物を含有させると、好ましくない着色,着臭が見られたり、製剤安定性の低下が見られたりすることがあった。複数の植物や菌類抽出物を併用して作用効果の増強を図る試みもなされてはいるが、皮膚の生理機能には種々の因子が複雑に関与するため、皮膚の状態を十分に向上させることは困難である。
【0004】
一方、本発明に係る皮膚外用剤を得る際に用いるシラン(Bletilla striata (Thunb.) Reichb. f.)は、日本及び中国に分布するラン科(Orchidaceae)の多年性草本の一種である。また、シランの地下鱗茎を乾燥調製したものは、生薬「ビャッキュウ(BLETILLAE TUBER)」として知られており、古来より止血,排膿,粘滑等の薬効を備えた生薬処方の一つとして用いられている。
【0005】
シラン抽出物を配合する皮膚外用剤,化粧料としては、保水性に優れ且つ脂性肌に適応した化粧料(特許文献1)、タウリンとの併用により、老化に伴って菲薄化した皮膚の柔軟性、弾力性を改善し、細胞を賦活化して皮膚の老化を防止する皮膚外用剤(特許文献2)、しみ,そばかす,色黒等の予防又は症状の緩和や増悪の抑制、肌の美白化を目的とした皮膚外用剤(特許文献3)、皮膚の弾性力低下に起因するシワ、たるみを生ずるとされているメイラード反応を阻害するメイラード反応阻害剤(特許文献4)、ストレスの皮膚への影響を予防・改善・抑制することが出来、ストレスに起因する皮膚の不調に対応することが出来る皮膚外用組成物(特許文献5)、脱毛,ニキビ等の予防,治療に有効であるテストステロン−5α−レダクターゼ阻害剤(特許文献6)等が開示されている。
【0006】
しかしながら、シラン抽出物と、本願発明の特定の植物及び菌類抽出物から選ばれる1種又は2種以上を併用することに関する具体的な例示、更に、これらを併用することにより、皮膚になじみやすく、高い皮膚保湿効果,美肌効果及び肌荒れ改善効果を発揮し得る皮膚外用剤を得ることができるという本発明の顕著な効果については、上記文献等において何ら記載されていなかった。

つづいて、本発明において用いる植物及び菌類抽出物の抽出方法について述べる。
【0031】
本発明において、上記各植物及び菌類は生のまま抽出操作に供しても良いが、抽出効率を考えると細切,乾燥,粉砕等の処理を行った後抽出を行うことが好ましい。抽出は、抽出溶媒に浸漬して行う。抽出効率を上げるため撹拌を行ったり、抽出溶媒中でホモジナイズしても良い。抽出温度としては、5℃程度から抽出溶媒の沸点以下の温度とするのが適切である。抽出時間は抽出溶媒の種類,抽出温度によっても異なるが、4時間〜14日間程度とするのが適切である。また、超臨界流体,亜臨界流体を用いた抽出方法をとることもできる。
【0032】
抽出溶媒としては、水を用いることが最も好ましいが、そのほか、メタノール,エタノール,プロパノール,イソプロパノール等の低級アルコール、1,3−ブチレングリコール,プロピレングリコール,ジプロピレングリコール,グリセリン等の多価アルコール、ジエチルエーテル,ジプロピルエーテル等のエーテル類、酢酸エチル,酢酸ブチル等のエステル類、アセトン,エチルメチルケトン等のケトン類等の極性有機溶媒、また、生理食塩水,リン酸緩衝液,リン酸緩衝生理食塩水等、あるいは石油エーテル,n−ヘキサン,n−ペンタン,n−ブタン,n−オクタン,シクロヘキサン等の炭化水素類、四塩化炭素,クロロホルム,ジクロロメタン,トリクロロエチレン,ベンゼン,トルエンなどの無極性若しくは低極性溶媒から選択される1種又は2種以上の溶媒を好適に使用することができる。また、抽出に水,二酸化炭素,エチレン,プロピレン,エタノール,メタノール,アンモニア等の超臨界流体,亜臨界流体を用いても良く、この際エントレーナーとして上記の溶媒を用いることもできる。
【0033】
また、抽出物はそのままでも外用剤基剤に添加できるが、濃縮,乾固したものを水,極性溶媒に再度溶解したり、あるいは脱色,脱臭,脱塩等の精製処理,分画処理を行った後に用いても良い。また保存のためには、精製処理の後凍結乾燥し、用時に溶媒に溶解して用いることが好ましい。あるいは、リポソーム等のベシクル,マイクロカプセル等に内包させることもできる。
【0034】
本発明における上述の植物及び菌類抽出物の皮膚外用剤に対する配合量としては、好ましくは0.00001〜5重量%、特に0.0001〜1重量%の範囲である。この範囲であれば、シラン抽出物と、特定の植物及び菌類抽出物を組み合わせて配合した場合、製剤及び製剤中の植物及び菌類抽出物の経時安定性に影響を及ぼすことが無く、より高い効果を発揮させることができる。
【0035】
本発明に係る皮膚外用剤は、ローション剤,乳剤,ゲル剤,クリーム剤,軟膏剤,粉末剤,顆粒剤等、種々の剤型で提供することができる。また、化粧水,乳液,クリーム,美容液,パック等の皮膚化粧料、メイクアップベースローション,メイクアップベースクリーム等の下地化粧料、乳液状,油性,固形状等の各剤型のファンデーション,アイカラー,チークカラー等のメイクアップ化粧料、クレンジングクリーム,クレンジングローション,クレンジングフォーム,洗顔石鹸,ボディシャンプー等の皮膚洗浄料、ヘアーシャンプー,ヘアーリンス,ヘアートリートメント等の毛髪用化粧料等としても提供することができる。
