Description

【0001】
【発明の属する技術分野】
本発明は、複数の植物抽出物を併用して含有して成り、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】
従来より、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(フレグランス ジャーナル,臨時増刊第1号,1979年、同誌,臨時増刊第6号,1986年等)。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抽出物を含有させると、好ましくない着色や着臭が見られたり、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】
【発明が解決しようとする課題】
そこで本発明においては、皮膚の生理機能を十分に向上させることにより、高い皮膚保湿効果,美肌効果及び肌荒れ改善効果を発揮することができ、且つ皮膚とのなじみもよく、製剤安定性及び安全性に優れる皮膚外用剤を得ることを目的とした。
【0005】
【課題を解決するための手段】
上記の課題を解決するべく種々検討した結果、特定の植物より選択した1種又は2種以上と、特定の植物及び菌類の抽出物を組み合わせて含有させることにより、良好な結果が得られることを見いだし、本発明を完成するに至った。
【0006】
すなわち、本発明においては、
1.フキタンポポ,メリロートから選択される1種又は2種の植物抽出物と、ナツメ抽出物
2.フキタンポポ,メリロートから選択される1種又は2種の植物抽出物と、オウレン抽出物
3.メリロート抽出物と、コガネヤナギ抽出物
4.メリロート抽出物と、ブクリョウタケ抽出物
5.メリロート抽出物と、キハダ抽出物
6.フキタンポポ,メリロートから選択される1種又は2種の植物抽出物と、ウコン抽出物
7.フキタンポポ,メリロートから選択される1種又は2種の植物抽出物と、ショウガ抽出物

をそれぞれ組み合わせて保湿,肌荒れ改善用皮膚外用剤に配合する。
【0007】
【発明の実施の形態】
本発明において用いる植物及び菌類について説明する。
【0011】
本発明において用いるフキタンポポ(Tussilago farfara L.)はキク科(Compositae)に属する多年草で、葉,茎,花,根等の各部位及び全草を用いることができるが、葉又は花を用いることが好ましい。
【0026】
本発明において用いるメリロート(Melilotuis officinalis L.)は、マメ科(Leguminosae)に属する越年草で、葉,茎,花,果実等の各部位及び全草を用いることができるが、葉,茎などの地上部位を用いることが好ましい。
【0032】
本発明において用いるナツメ(Ziziphus jujuba Mill.)は、クロウメモドキ科(Rhamnaceae)に属する高木で、葉,枝,幹,樹皮,根,花,果実等の各部位を用いることができるが、果実を用いることが好ましい。また、ナツメの果実を乾燥させたものは、「タイソウ」と呼ばれる生薬であり、かかる生薬を用いることもできる。
【0033】
本発明において用いるオウレン(Coptis japonica (Thunb.) Makino)は、キンポウゲ科(Ranunculaceae)に属する多年草で、葉,茎,花,果実,根等の各部位及び全草を用いることができるが、根を用いることが好ましい。また、オウレンの根茎は、「オウレン」と呼ばれる生薬であり、かかる生薬を用いることもできる。
【0043】
本発明において用いるウコン(Curcuma domestica Valet.)は、ショウガ科(Zingiberaceae)に属する多年草で、葉,茎,花,果実,根等の各部位及び全草を用いることができるが、根茎を用いることが好ましい。また、ウコンの根茎を乾燥させたものは「ウコン」と呼ばれる生薬の一種であり、かかる生薬を用いることもできる。
【0046】
本発明において用いるショウガ(Zingiber officinale Rosc.)は、ショウガ科(Zingiberaceae)に属する多年草で、葉,茎,花,果実,根等の各部位及び全草を用いることができるが、根茎を用いることが好ましい。また、ショウガの根茎を乾燥させたものは「ショウキョウ」と呼ばれる生薬の一種であり、かかる生薬を用いることもできる。
【0054】

【0056】
続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。
【0057】
本発明において、上記各植物及び菌類は生のまま抽出に供してもよいが、抽出効率を考えると、細切,乾燥,粉砕等の処理を行った後に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よい。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や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。
【0058】
抽出溶媒としては、水の他、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、エチルエーテル,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などの極性有機溶媒を用いることができ、これらより1種又は2種以上を選択して用いる。また、生理食塩水,リン酸緩衝液,リン酸緩衝生理食塩水等を用いてもよい。
【0059】
上記植物及び菌類の上記溶媒による抽出物は、そのままでも本発明に係る皮膚外用剤に含有させることができるが、濃縮,乾固したものを水や極性溶媒に再度溶解したり、或いはそれらの皮膚生理機能向上作用を損なわない範囲で脱色,脱臭,脱塩等の精製処理を行ったり、カラムクロマトグラフィーによる分画処理を行った後に用いてもよい。また保存のため、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もできる。また、リポソーム等のベシクルやマイクロカプセル等に内包させて用いることもできる。
【0060】
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への配合量としては、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、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。
【0061】
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。
【0062】
なお本発明に係る皮膚外用剤には、上記植物及び菌類の抽出物の他に、油性成分,界面活性剤,保湿剤,顔料,紫外線吸収剤,抗酸化剤,香料,防菌防黴剤等の一般的な医薬品及び化粧料用原料や、皮膚細胞賦活剤,抗炎症剤,美白剤等の生理活性成分をも含有させることができる。
【0063】
【実施例】
さらに本発明の特徴について、実施例により詳細に説明する。まず、本発明において用いる植物の各抽出物の調製例について以下に示す。
【0064】
[調製例1〜49]
表1に示した植物及び菌類各200gを乾燥,粉砕し、50容量%エタノール水溶液各1リットル中にて20℃で3日間撹拌抽出した後、ろ過してろ液を回収し、調製例1〜調製例49に係る植物抽出物を得た。

製法:(1)〜(7)の油相成分を混合し、加熱溶解して75℃とする。一方(8)〜(10)の水相成分を混合,溶解して75℃に加熱する。次いで、この水相成分に前記油相成分を添加して予備乳化した後ホモミキサーで均一に乳化し、冷却後40℃にて(11)及び(12)を添加,混合する。

上記本発明の実施例1〜実施例62及び比較例1〜比較例49について、肌荒れ改善効果を検討した。25〜50才の健常人10名を一群として、実験的な荒れ肌を誘起する前の肌状態をマイクロスコープで撮影し、表5に示した基準によりそのスコアを求めた。実験的な荒れ肌は、上腕内側部をエーテル、アセトン(1:1容量比)混液にて処理することにより誘起した。さらにその後は7日間にわたって毎日朝と夜の2回被験美容液を塗布し、荒れ肌誘起の1日後及び7日後に前記と同様肌状態のスコアを求めた。同時に、荒れ肌誘起の1日後及び7日後に塗布部位角質層の水分量の測定を行った。角質層水分量は、皮膚表面コンダクタンスの測定値(μムーオ)により示した。結果を表6〜表9に示す。

表6〜表9に示したとおり、本発明の実施例1〜実施例62にかかる、特定の植物及び菌類の抽出物を併用して配合した美容液を皮膚に適用することにより、肌荒れ改善効果を示し、角質層水分量が上昇することが明らかになった。これに対し、植物及び菌類の抽出物を単独、若しくは全く配合していない比較例1〜比較例49においては、肌荒れ改善及び角質層水分量の増加傾向は認められるものの、その効果は実施例より明らかに低いものであった。
【0078】
さらに、各群のパネラーに、被験美容液の皮膚へのなじみやすさを評価させた。また使用試験期間中に、試料を使用した際に皮膚刺激感を感じたり、紅斑や発疹等の異常があったかどうかについて聞き取り調査を行った。皮膚へのなじみやすさと、皮膚刺激感及び皮膚異常の有無については、表10に示す評価基準に従って点数化させ、10名の平均値を算出した。これらの結果は表11及び表12にまとめて示した。

表11及び表12において、本発明の実施例1〜実施例62使用群は、いずれについても皮膚とのなじみが良好であるとの評価が得られた。また今回使用試験に供した各試料については、表11に示すように問題となる皮膚刺激感や皮膚異常は認められていなかった。

The present invention relates to an external preparation for skin, comprising a combination of a plurality of plant extracts, easily adaptable to the skin, and capable of exhibiting a high skin moisturizing effect, skin beautifying effect and rough skin improving effect.
[0002]
[Prior art]
Conventionally, extracts of many kinds of plants including medicinal plants have been used for external preparations of the skin (Fragrance Journal, Extra Number 1, Extra 1979, the same magazine, Extra Special No. 6, 1986, etc.) . In recent years, there has been an increasing tendency to seek active ingredients in plant extracts in response to an increase in plant orientation due to nature and animal welfare.
[0003]
However, although plant extracts each have a variety of actions, the actions are generally not so strong, and it is not preferable to add a plant extract in an amount that produces the expected action and effect in a topical skin preparation. In some cases, coloring or odor was observed, or the stability of the preparation was decreased. Although attempts have been made to enhance the action and effect by using multiple plant extracts, it is difficult to improve the skin condition sufficiently because various factors are involved in the physiological functions of the skin. It is.

Production method: The oil phase components (1) to (7) are mixed and dissolved by heating to 75 ° C. On the other hand, the water phase components (8) to (10) are mixed, dissolved, and heated to 75 ° C. Next, the oil phase component is added to the aqueous phase component and pre-emulsified, and then uniformly emulsified with a homomixer. After cooling, (11) and (12) are added and mixed at 40 ° C.

With respect to Examples 1 to 62 and Comparative Examples 1 to 49 of the present invention, the effect of improving skin roughness was examined. A group of 10 healthy people aged 25 to 50 years old was photographed with a microscope for the skin condition before inducing experimental rough skin, and the score was determined according to the criteria shown in Table 5. Experimental rough skin was induced by treating the inner side of the upper arm with a mixture of ether and acetone (1: 1 volume ratio). Thereafter, the test serum was applied twice a day in the morning and night every day for 7 days, and the score of the skin condition was determined in the same manner as described above 1 day and 7 days after the induction of rough skin. At the same time, the moisture content of the stratum corneum applied site was measured 1 day and 7 days after the induction of rough skin. The stratum corneum moisture content was shown by the measured value (μ muo) of skin surface conductance. The results are shown in Tables 6-9.

As shown in Tables 6 to 9, by applying to the skin a cosmetic liquid formulated with a specific plant and fungal extract according to Examples 1 to 62 of the present invention, the effect of improving rough skin It was revealed that the stratum corneum water content increased. On the other hand, in Comparative Examples 1 to 49 in which extracts of plants and fungi were singly or not blended at all, improvement in skin roughness and an increase in the amount of water in the stratum corneum were observed, but the effect was more than in the examples It was clearly low.
[0078]
Further, each group of panelists was asked to evaluate the familiarity of the test serum with the skin. In addition, during the use test period, an interview survey was conducted to determine whether skin irritation was felt when the sample was used, and whether there were abnormalities such as erythema and rash. The familiarity with the skin, the feeling of skin irritation and the presence or absence of skin abnormality were scored according to the evaluation criteria shown in Table 10, and the average value of 10 persons was calculated. These results are summarized in Tables 11 and 12.
