【課題を解決するための手段】
すなわち、本発明は安全性が高く皮膚の代謝を向上させ、皮膚の形成に必須なたんぱくの産生を促し、しかも紫外線などの外的刺激要因から皮膚を保護する効果を有し、肌老化及び肌荒れ改善、予防する作用のある皮膚化粧料を提供する。
【0007】
【発明の実施の形態】
以下に本発明について詳細に記載する。本発明に使用されるアルテミアエキスは海洋フ゜ランクトン、アルテミア(Artemia Salina 和名:ホウネンエヒ゛)の孵化直前の耐久卵から水抽出したエキスでたんぱくおよび生体高エネルキ゛ー分子であるシ゛ク゛アノシンテトラフォスフェートを主成分とする。
【0008】
本発明者らは、海洋フ゜ランクトン、アルテミア(Artemia Salina 和名:ホウネンエヒ゛)の孵化直前の耐久卵から水抽出したエキスを本皮膚化粧料に配合した。
【0009】
本発明においてアルテミアエキスは抽出溶媒としてエタノール、フ゜ロヒ゜レンク゛リコール、1.3−フ゛チレンク゛リコールやク゛リセリンなどのアルコール類、アセトン、酢酸エチルなどの有機溶媒、水、含水アルコールなどをそれぞれ単独、あるいは組み合わせて用いることが出来る。本発明に使用される本品は淡黄色の透明な液体で特異なにおいがある。
【0010】
本発明においてアルテミアエキスは皮膚化粧料、特にスキンケア剤に0.01から10%、好ましくは0.5から5%が推奨できる範囲が充分効果の発揮され好ましい。一方、この範囲濃度以上の配合は充分に効果の発揮され難く製品の配合上、使用感や安定性の点からも好ましくない。
【0011】
本物質の熱安定性は高く、乳化物に使用しても安定である。また本物質の溶解性はフ゜ロヒ゜レンク゛リコール、エタノール、ヒマシ油、また水に溶解することが出来る。
【0012】
次にアルテミアエキスの皮膚への効果を確認するためにインヒ゛トロレヘ゛ルによる細胞の代謝活性化と皮膚構成たんぱくの合成促進作用及びDNA保護作用を調べた結果、即効的且つ強力なセルリハ゛ラタライサ゛ーとして、皮膚代謝を向上させ、皮膚形成に必須のたんぱく産生を促し、DNAを紫外線などの要因から守る作用があることを発見した。
【0013】
(細胞の代謝活性化と皮膚構成たんぱくの合成促進作用)細胞の代謝活性化と皮膚構成たんぱくの合成促進作用の指標としてc−AMPの増殖作用、コラーケ゛ンI、IIIの合成作用、フィラク゛リンの合成促進作用、ケラチン繊維を凝集させる顆粒層たんぱくの合成促進、ケラチン合成促進作用及びフィフ゛ロネクチン合成促進作用、さらにはDNA保護作用について検討した。
【0014】
その結果、c−AMPの増殖作用では本品2%処理したヒトフィフ゛ロフ゛ラスト培養細胞は非処理同一細胞に比較して40%のc−AMPの増殖が認められ、コラーケ゛ンI、IIIの合成作用において本品1%処理ヒトフィフ゛ロフ゛ラスト培養細胞において、非処理同一細胞に比べ、50%の合成促進作用が確認された。同様に本品1%処理ヒトフィフ゛ロフ゛ラスト培養細胞において表皮細胞マーカーとしてのヒトフィラク゛リンを蛍光染色により観察した結果、非処理同一細胞に比べ明らかな合成促進作用が確認された。また、ケラチン合成促進作用ではヒトケラチノサイト培養細胞に本品1%を処理し10時間後及び20時間後の電気泳動によってたんぱくを分離し免疫染色法によりケラチンを定量した結果、約25%、68%のケラチン合成促進が確認された。フィフ゛ロネクチンは細胞と細胞外マトリックス間の接着因子として知られており、本品1%処理ヒトフィフ゛ロフ゛ラスト培養細胞における合成促進作用は非処理同一細胞に比べ27%の増加が確認された。次に紫外線を24時間ケラチノサイト細胞に照射前、照射後に本品を処理し、非処理同一細胞に比べた結果、細胞の壊死率は明らかに低減し、またアクチノマイシンによる細胞壊死率も低減され、本品がDNA保護作用に関与していることが示唆された。また、フリーラシ゛カル消去作用についてもアルテミアエキスは、同様な作用が公知されているサリチル酸と比較して、優れたフリーラシ゛カル消去効果があることが判明した。
【0015】
インヒ゛ホ゛レヘ゛ルの試験では損傷部位に本品を6日間連続塗布し、タ゛イナモメーターで損傷部位の引っ張り強度を測定した。その結果、治癒期間の短縮と皮膚弾力性を向上させる結果が得られ、優れた皮膚への作用があることが証明された。
【0016】
一方、本品の安全性については皮膚一次刺激性試験、皮膚感作性試験、急性経口毒性試験、眼粘膜刺激性試験、光毒性試験、変異原性試験及びヒトハ゜ッチテスト(皮膚貼付試験)を実施し、いずれも問題はなかった。

DETAILED DESCRIPTION OF THE INVENTION
The present invention is described in detail below. The artemia extract used in the present invention is an extract extracted from a durable egg just before the hatching of marine plankton and artemia (Artemia Salina Japanese name: Honnen), and is mainly composed of protein and diganosin tetraphosphate which is a biologically high energy molecule. To do.
[0008]
The inventors of the present invention formulated an extract obtained by extracting water from a durable egg just before the hatching of marine plankton and artemia (Artemia Salina Japanese name: Hounen).
[0009]
In the present invention, the artemia extract is used as an extraction solvent with ethanol, fluoroethylene glycol, alcohols such as 1.3-butylene glycol and glycerin, organic solvents such as acetone and ethyl acetate, water, hydrous alcohol, etc., either alone or in combination. I can do it. The product used in the present invention is a pale yellow transparent liquid with a unique odor.
[0010]
In the present invention, the artemia extract is preferably used in a range where 0.01 to 10%, preferably 0.5 to 5% can be recommended for skin cosmetics, particularly skin care agents. On the other hand, blending at a concentration over this range is not preferred from the standpoints of usability and stability in terms of blending of the product, since it is difficult to exert its effect sufficiently.
[0011]
This material has high thermal stability and is stable when used in emulsions. The solubility of this substance can be dissolved in fluorene glycol, ethanol, castor oil, and water.
[0012]
Next, in order to confirm the effect of Artemia extract on the skin, the metabolic activation of cells by in vitro level, the synthesis promoting action of skin constituent proteins, and the DNA protecting action were examined. As a result, the skin was rapidly and powerfully used as a cellular regulator. It has been discovered that it improves metabolism, promotes protein production essential for skin formation, and protects DNA from factors such as ultraviolet rays.
[0013]
(Cell metabolism activation and skin composition protein synthesis promoting action) c-AMP proliferation action, collagen I and III synthesis action, fibrillin synthesis promotion as indicators of cell metabolism activation and skin composition protein synthesis promotion action Studies were made on the action, the synthesis of granule layer protein that aggregates keratin fibers, the action of promoting keratin synthesis, the action of promoting fibronectin synthesis, and the DNA protecting action.
[0014]
As a result, in the proliferative effect of c-AMP, cultured human fibroblast cells treated with 2% of this product showed 40% proliferation of c-AMP compared to untreated identical cells, and in the synthesis of collagens I and III. In this product 1% -treated human fibroblast cultured cells, 50% of the synthesis promoting action was confirmed compared to the untreated identical cells. Similarly, as a result of observing human fibrin as an epidermal cell marker by fluorescent staining in 1% -treated human fibroblast cultured cells of this product, a clear synthesis promoting action was confirmed as compared with the untreated identical cells. Further, in the keratin synthesis promoting action, human keratinocyte cultured cells were treated with 1% of this product, the protein was separated by electrophoresis after 10 hours and 20 hours, and keratin was quantified by immunostaining. As a result, about 25%, 68% Of keratin synthesis was confirmed. Fibronectin is known as an adhesion factor between cells and extracellular matrix, and it was confirmed that the synthesis promoting action in this 1% -treated human fibroblast cultured cell was increased by 27% compared to the untreated identical cells. Next, this product was treated before and after irradiating keratinocyte cells with ultraviolet rays for 24 hours, and as a result of comparing with untreated identical cells, the cell necrosis rate was clearly reduced, and the cell necrosis rate due to actinomycin was also reduced. It was suggested that this product is involved in DNA protection. Further, regarding the free radical scavenging action, it has been found that Artemia extract has an excellent free radical scavenging effect as compared to salicylic acid, which is known to have a similar action.
[0015]
In the in-vivo level test, the product was continuously applied to the damaged site for 6 days, and the tensile strength of the damaged site was measured with a dynamometer. As a result, shortening of the healing period and improvement of skin elasticity were obtained, and it was proved that there was an excellent action on the skin.
[0016]
On the other hand, regarding the safety of this product, primary skin irritation test, skin sensitization test, acute oral toxicity test, ocular mucosal irritation test, phototoxicity test, mutagenicity test and human hatch test (skin patch test) There was no problem.
