Description

【0001】
【発明の属する技術分野】
本発明は、抗酸化剤、及び抗酸化効果に優れ、皮膚の老化症状の防止と改善に優れた皮膚外用剤に関する。
【0002】
【従来の技術】
紫外線等の外来ストレスによって生じる活性酸素やフリーラジカルは、皮膚細胞に損傷を与えるだけでなく、皮膚マトリックスの破壊や過酸化脂質の生成に関与し、シワや皮膚弾性の低下といった老化症状を引き起こす要因となっている。これまでの皮膚外用剤の分野では、係る老化を防止あるいは改善するために、様々な抗酸化剤の検索及び配合検討がなされてきた。抗酸化剤としては、トコフェロール(ビタミンE),BHT(ジブチルヒドロキシトルエン)の他、様々な植物由来成分、例えば、キク科へテロテカ属植物抽出物(特開平11−180886)やカユアンギンの抽出物(特開平10−182413)等が知られている。
【0003】
【発明が解決しようとする課題】
しかしながら、上記の有効成分を含有する皮膚外用剤はいずれにおいてもその抗酸化効果、老化防止や改善効果は必ずしも十分ではなく、皮膚外用剤の基剤中に配合した場合、有効な効果を得るにはかなりの高濃度を配合しなければならず、製剤に好ましくない色や臭いを付与してしまう場合があるなど、作用効果や安定性の面ですべてを満足できるものが少ないのが現状であった。本発明は、上記事情に鑑みてなされたものであり、その課題は、優れた抗酸化剤と、抗酸化効果に優れ、老化の防止や改善効果に優れた皮膚外用剤を提供することにある。
【0004】
【課題を解決するための手段】
本発明者らは、上記課題を解決するために、抗酸化効果に優れ、老化の防止や改善効果に優れた成分を得るべく鋭意研究を重ねた結果、クビレヅタ(Caurelpa lentillifera)の抽出物が、優れた抗酸化剤であり、係る抗酸化剤を皮膚外用剤に配合することにより、老化の防止や改善効果に優れていることを見出し、本発明を完成するに至った。
【0005】
すなわち、本発明は、クビレヅタ(Caurelpa lentillifera)の抽出物を含有する抗酸化剤及び皮膚外用剤を提供するものである。
【0006】
クビレヅタあるいはその近縁種の利用としては、ヒアルロニダーゼ阻害剤(特開平09−67266),スリミング剤(特開2000−72642),育毛剤(特2001−55314)がこれまでに開示されている。
【0007】
しかし、クビレヅタ抽出物が抗酸化効果に優れていること、さらに係るクビレヅタ抽出物を皮膚外用剤に配合することにより、老化の防止や改善に優れた効果を発揮することに関しては、本発明により初めて明らかとなったことである。
【0008】
【発明の実施の形態】
本発明は、クビレヅタ(Caurelpa lentillifera)の抽出物を含有する抗酸化剤及び皮膚外用剤にかかるものである。
【0009】
本発明においては、クビレヅタ抽出物を皮膚外用剤に配合することにより、老化の防止や改善に優れた効果を発揮する。
【0010】
本発明で用いるクビレヅタ抽出物の出発原料となるクビレヅタ(Caurelpa lentillifera)は、緑藻綱イワヅタ科(Caurelpac eae)イワヅタ属(Caulerpa)に属する海藻である。南西諸島,フィリピン,ミクロネシア,紅海等に広く分布しており、ウミブドウとも言われ、食品としても市販されている。
【0011】
クビレヅタの抽出物を得る際は、クビレヅタを生のまま、若しくは細切,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、抽出溶媒に浸漬するか、超臨界流体や亜臨界流体を用いた抽出方法でも行うことができる。抽出効率を上げるため、撹拌や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、1時間〜14日間程度とするのが適切である。
【0012】
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、酢酸エステル,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。さらに、水や二酸化炭素,エチレン,プロピレン,エタノール,メタノール,アンモニアなどの1種又は2種以上の超臨界流体や亜臨界流体を用いてもよい。
【0013】
クビレヅタの上記溶媒による抽出物は、そのままでも使用することができるが、濃縮,乾固した物を水や極性溶媒に再度溶解したり、或いはこれらの生理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等による分画処理を行った後に用いてもよい。クビレヅタの前記抽出物やその処理物及び分画物は、各処理及び分画後に凍結乾燥し、要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。
【0014】
本発明におけるクビレヅタ抽出物の配合量は、皮膚外用剤の種類や目的等によって調整することができるが、皮膚外用剤の全量に対して、0.0001〜10.0重量%が好ましく、より好ましくは、0.001〜5.0重量%である。
【0015】
本発明に係る皮膚外用剤の剤型は任意であり、例えばローションなどの可溶化系、クリームや乳液などの乳化系,カラミンローション等の分散系として提供することができる。さらに、噴射剤と共に充填したエアゾール,軟膏剤,粉末,顆粒などの種々の剤型で提供することもできる。
【0016】
なお、本発明に係る皮膚外用剤には、クビレヅタ抽出物の他に、必要に応じて、通常医薬品,医薬部外品,皮膚化粧料,毛髪用化粧料及び洗浄料に配合される、油性成分,保湿剤,粉体,色素,乳化剤,可溶化剤,洗浄剤,紫外線吸収剤,増粘剤,薬剤,香料,樹脂,防菌防黴剤,アルコール類等を適宜配合することができる。また、本発明の効果を損なわない範囲において、他の抗酸化剤や抽出物との併用も可能である。

It is widely distributed in the Southwest Islands, the Philippines, Micronesia, the Red Sea, etc., and is also called sea grapes, and is commercially available as food.
[0011]
When obtaining an extract of crevice, it is preferable to extract the crevice as it is or after performing processing such as shredding, drying, and pulverization. The extraction can be performed by immersion in an extraction solvent or by an extraction method using a supercritical fluid or a subcritical fluid. In order to increase the extraction efficiency, homogenization may be performed with stirring or in an extraction solvent. It is appropriate to set the extraction temperature at a temperature of about 5 ° C. to the boiling point of the extraction solvent or lower. The extraction time varies depending on the type of the extraction solvent and the extraction temperature, but is suitably about 1 hour to 14 days.
[0012]
Examples of the extraction solvent include water, lower alcohols such as methanol, ethanol, propanol and isopropanol, polyhydric alcohols such as 1,3-butylene glycol, propylene glycol, dipropylene glycol and glycerin, and ethers such as ethyl ether and propyl ether. And solvents such as esters, acetates, butyl acetate and the like, and ketones such as acetone and ethyl methyl ketone. One or more of these can be selected and used. Further, physiological saline, phosphate buffer, phosphate buffered saline, or the like may be used. Further, one or more supercritical fluids or subcritical fluids such as water, carbon dioxide, ethylene, propylene, ethanol, methanol, and ammonia may be used.
[0013]
The extract of the cigarette from the above solvent can be used as it is, but the concentrated and dried extract may be redissolved in water or a polar solvent, or decolorized, deodorized, and decolored to the extent that these physiological actions are not impaired. It may be used after purifying a salt or the like or fractionating by column chromatography or the like. The extract or processed product and fractionated product of the millet can be lyophilized after each treatment and fractionation, and used by dissolving in a solvent when necessary. It can also be used by being encapsulated in vesicles such as liposomes or microcapsules.
[0014]
The blending amount of the extract of the present invention can be adjusted depending on the type and purpose of the external preparation for skin, but is preferably 0.0001 to 10.0% by weight, more preferably 0.0001 to 10.0% by weight, based on the total amount of the external preparation for skin. Is 0.001 to 5.0% by weight.
[0015]
The dosage form of the external preparation for skin according to the present invention is arbitrary, and can be provided, for example, as a solubilizing system such as a lotion, an emulsifying system such as a cream or an emulsion, or a dispersion system such as a calamine lotion. Furthermore, it can be provided in various dosage forms such as an aerosol, an ointment, a powder, and a granule filled together with a propellant.
