Description

【0001】
【発明の属する分野】
本発明は各種成分による皮膚、頭皮および粘膜への刺激を緩和したり抑制したりする皮膚外用剤に関する。
【0002】
【従来の技術】
生活環境の変化により人間は常に各種刺激物質に曝されている。このため鼻炎、アトピー性皮膚炎や花粉症、喘息など患者の増大、また過去に存在しなかったような疾患などが増えてきており大きな社会問題となっている。我々は各種刺激物質に曝されているため皮膚が過敏になり、また今まで刺激を起こさなかった物質などに敏感に反応してしまう人や、また皮膚外用剤の有効成分として配合された物質などによる炎症が報告されており、皮膚科学分野において問題となっている。
【0003】
従来はこれまで使用してきた商品の使用を中止したり、これら炎症に対して炎症がおこってから抗炎症剤配合の外用剤を塗布して炎症を鎮めたり、あるいは予防を目的として、各種の保湿剤を使用することにより表皮を保護して皮膚機能を高めたりする対策がとられている。
【0004】
一方、これらの目的のためにさまざまな試みがなされている。例をあげるならば炎症を抑制したり、緩和させたりする目的でクララ、ホウセンカなど多様な植物抽出物が利用されている(特許公開公報2000−044481号、特許公開公報 平11−180852号、特許公開公報 平11−012122号)。また多価アルコールの利用についてはポリプロピレングリコール、ポリアルキレングリコール、ポリエチレングリコールによる効果も提案されている(特許公開公報2000−284705号、特許公開公報2000−212044号)。また、ヒアルロン酸やトレハロースなどによる糖の刺激抑制も行なわれている(特許公開公報 平10−017430号、特許公開公報平10−045560号、特許公開公報 平10−017427号)。また、副腎皮質ホルモンなどのステロイド剤や各種抗炎症剤(消炎剤)の使用も市販外用剤中や皮膚科などの医療現場などの場で繁用されている。しかしながら安全性はもちろんのこと、得られる効果もまた未だ理想的に満足できるものではなかった。
【0005】
【発明が解決しようとする課題】
本発明は上記従来からの技術の課題に鑑みて、その目的は皮膚の炎症や刺激を抑制したり軽減する効果に優れた皮膚外用剤を提供するものである。
【0006】
【課題を解決するための手段】
本発明者等はこのような事情に鑑み、鋭意検討した結果、水深2500〜3000メーターで生存する微小生物であるAlteromonas macleodiiが生成、分泌する外分泌性ポリサッカライド、アルテロモナス発酵エキスが皮膚炎症や刺激を抑制したり軽減する効果についての知見を得て、本発明を完成するに至った。以下、本発明について詳細に説明する。

【0009】
ポリサッカライド複合体の製造法はAlteromonas macleodii菌(グラム陰性菌)を培養して、分泌させ、これらを集め、特殊な方法により沈殿、精製、乾燥して製造する。皮膚外用剤に使用する際には取り扱いや剤型中への配合性を良くする目的で上記で得たアルテロモナス発酵エキス0.3g、ブチレングリコール4.0g、防腐剤0.5gおよび精製水95.2g の組成物を含有した皮膚刺激緩和剤を使用した。この組成物の比重は1.00±0.01、pHは5.7±1.0であり透明な液状である。
【0010】
本発明の皮膚外用剤に使用する皮膚刺激緩和剤の好ましい濃度は0.01%から8.0%であり、より好ましい使用濃度は0.5%から5.0%である。皮膚外用剤の含有量が0.01%より少ないと皮膚炎症や刺激を抑制したり軽減する効果を発揮することは困難であり、8.0%以上の含有量では見合うような著しい効果の増大は期待できない。
【0011】
本発明の成分は化粧料、医薬品、医薬部外品など外皮に適用される皮膚外用剤として用いることができる。したがってその剤型として水溶性系(ローション系)、可溶化系、乳化系(W/O型、O/W型)、粉末系、軟膏系、油液系、ジェル系、水−油二層系、水−油−粉末三層系など幅広い形態に使用することができる。
【0012】
本発明の皮膚外用剤の製剤化は上記物質に加えて本発明の効果を損なわない範囲内で、通常の医薬品等の皮膚外用剤、医薬部外品や化粧品に用いられる他の成分、例えば陰イオン(高級脂肪酸アルカリ金属塩、高級脂肪酸アミン塩、アミノ酸系界面活性剤)や非イオン界面活性剤、リン脂質ステロールエステルなどの界面活性剤、炭化水素(流動パラフィン、スクワラン、ワセリンなど)、油脂(動植物油、トリグリセリド、ワックスエステル、高級アルコール、高級脂肪酸、シリコーン、エステル油、ロウ類など)など、湿潤剤(多価アルコール、糖類、生体高分子、アミノ酸、ペプチド類など)、アルコール(エチルアルコール)、皮膜形成剤(ポリビニルアルコール、ペクチン)や水溶性ないし油溶性高分子、樹脂、紫外線吸収剤、殺菌防腐剤、抗酸化剤、金属封鎖剤、着色剤(天然色素、合成色素)、各種香料の他、各種の植物および動物抽出物、油溶性ビタミン、水溶性ビタミンや美白剤として、アスコルビン酸誘導体、アルブチン、エラグ酸、胎盤抽出液、肌荒れ防止剤としてアラントイン、抗炎症剤としてグルチルレチン酸、グリチルリチン酸、アズレン、ヒスタミン剤など、抗老化剤としてビタミンAパルミテートなど、収斂剤としてパラフェノールスルフォン酸亜鉛や、クエン酸およびその塩などを含めた有機酸類とその塩等、そして紫外線散乱剤として有機あるいは無機系粉体等を、必要に応じて適宜配合もしくは併用することができる。
【0013】
本発明の皮膚外用剤は必要によりさらに公知の炎症効果のある薬剤を添加してもよい。これらの薬剤としては副腎皮質ホルモン類、レチノイド、トコフェロール、L−アスコルビン酸塩およびL−アスコルビン酸誘導体を含むビタミン類、インドメタシン、アラントイン、グリチルリチン酸およびその誘導体、グリチレレチン酸およびその誘導体、ヒアルロン酸類およびコラーゲンやコンドロイチン硫酸塩類や植物抽出液、ビオチン、パントテン酸誘導体などがあげられる。
【0014】
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、光感作性試験、変異原性試験およびヒトパッチテスト(皮膚貼付試験)を実施し、いずれも問題はなかった。
【0015】
以下に実験例および実施例をあげて本発明について更に説明するが、本発明がこれら例に何ら限定するものではない。
【0016】
【実験例1】培養ヒトケラチノサイトによるICAM−1の抑制率測定)
ICAM−1(Inter Celluar Adehesion Molecule−1)、細胞間接着分子は皮膚の反応性に関する最適マーカーである。皮膚などの組織では隣接した細胞同士は互いに接着している。この細胞間接着は接着分子と呼ばれる数郡の膜貫通型たんぱく質ファミリーにより仲介される。これらの接着分子は細胞を接着するだけでなく、様々な免疫細胞と組織細胞の接着やそのための情報伝達に非常に重要な役割を担っている。通常ICAM−1の発現は低いが、アレルゲンや炎症誘導物質などによりその発現レベルは明らかに増加するため、皮膚病理学の分野では皮膚の炎症反応などのマーカーとして利用されている。接触性アレルゲン、炎症性前駆物質により荒れ肌となった皮膚で、このIMCAM−1の増加を放置することにより、皮膚はアレルギー、過敏症など、不快感を伴う状態となる。皮膚刺激緩和剤はこのICAM−1の上昇を抑制するに極めて有効であり、肌に快適な状態をもたらす。そこでヒトケラチノサイト細胞に対し、対照(単独)、2.0%および5.0%皮膚刺激緩和剤を24時間処理後、ICAM−1の測定をおこなった。結果は図1に示した。
【0017】
図1から対照(単独)のICAM−1量が100に対し、2.0%皮膚刺激緩和剤でのICAM−1量は24で、76%の抑制を示し、5.0%皮膚刺激緩和剤のICAM−1量は15で85%の抑制であった。すなわち、ヒトケラチノサイトに対して ICAM−1の極めて有意な減少がみられた。皮膚刺激緩和剤はICAM−1の上昇を抑制するのに極めて有効であり、肌に快適な状態をもたらすことが判明した。
【0018】
【実験例2】培養ヒト皮膚繊維芽細胞によるコラーゲンのマトリックス化(ゲル化)の定量試験
ヒト繊維芽細胞懸濁液、コラーゲン溶液、被験物質を混合したコラーゲン溶液を調整して、培養皿に入れ、湿潤条件下で、インキューベートを行った。被験物質として、0.03%皮膚刺激緩和剤、レチノイン酸を用い、被験物質を含まないものをコントロールとした。コラーゲンマトリックス形成による収縮をマトリックスの直径を測定して比較した。
【0019】
コラーゲン溶液は、繊維芽細胞存在下でマトリックス化するとゲル状になり、溶液の体積は収縮する。図2に示したとおり、本試験により、0.03%皮膚刺激緩和剤は低濃度においてもコラーゲンマトリックスの形成を改善することがわかる。この結果は皮膚障害における組織の再構築に有効であることを示している。また、コラーゲンとの同時投与が有効であることを示唆している。

[Field of the Invention]
The present invention relates to an external preparation for skin that alleviates or suppresses irritation to skin, scalp and mucous membrane by various components.
[0002]
[Prior art]
Due to changes in the living environment, humans are constantly exposed to various stimulating substances. For this reason, the number of patients such as rhinitis, atopic dermatitis, hay fever and asthma is increasing, and diseases that did not exist in the past are increasing, which is a big social problem. Because we are exposed to various irritants, the skin becomes irritable, and people who react sensitively to substances that have not caused irritation until now, and substances formulated as active ingredients in skin external preparations, etc. Inflammation has been reported and is a problem in the field of dermatology.
[0003]
Various types of moisturizing agents have been used to stop the use of products that have been used so far, or to apply an external preparation containing an anti-inflammatory agent after inflammation has occurred, to reduce inflammation, or to prevent inflammation. Measures are taken to protect the epidermis and enhance skin function by using an agent.
[0004]
On the other hand, various attempts have been made for these purposes. For example, various plant extracts such as Clara and spinach are used for the purpose of suppressing or alleviating inflammation (Patent Publication No. 2000-044481, Patent Publication No. 11-180852, Patents). Publication No. 11-012122). In addition, the effects of polypropylene glycol, polyalkylene glycol, and polyethylene glycol have also been proposed for the use of polyhydric alcohols (Patent Publication Nos. 2000-284705 and 2000-212044). Further, suppression of sugar stimulation by hyaluronic acid, trehalose or the like has also been carried out (Patent Publication No. 10-014430, Patent Publication No. 10-045560, Patent Publication No. 10-01427). In addition, the use of steroidal agents such as corticosteroids and various anti-inflammatory agents (anti-inflammatory agents) is frequently used in commercially available external preparations and in medical settings such as dermatology. However, in addition to safety, the obtained effect has not yet been ideally satisfied.
[0005]
[Problems to be solved by the invention]
The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a skin external preparation excellent in the effect of suppressing or reducing skin inflammation and irritation.
[0006]
[Means for Solving the Problems]
As a result of diligent studies in view of such circumstances, the present inventors, as a result of the exocrine polysaccharide and Alteromonas fermented extract, produced and secreted by Alteromonas macleodii, a micro organism that survives at a water depth of 2500 to 3000 meters, cause skin inflammation and irritation. Obtaining knowledge about the effect of suppressing or reducing, the present invention has been completed. Hereinafter, the present invention will be described in detail.

[0014]
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, photosensitization test, mutagenicity test and human patch test (Skin application test) was conducted, and there was no problem in any case.
[0015]
Hereinafter, the present invention will be further described with reference to experimental examples and examples, but the present invention is not limited to these examples.
[0016]
[Experimental Example 1] Measurement of inhibition rate of ICAM-1 by cultured human keratinocytes)
ICAM-1 (Inter Cellular Adhesion Molecule-1), an intercellular adhesion molecule, is the optimal marker for skin reactivity. In tissues such as skin, adjacent cells adhere to each other. This intercellular adhesion is mediated by several groups of transmembrane proteins called adhesion molecules. These adhesion molecules not only adhere cells, but also play a very important role in the adhesion between various immune cells and tissue cells and the transmission of information. Although the expression level of ICAM-1 is usually low, its expression level is clearly increased by allergens, inflammation-inducing substances, and the like, so that it is used as a marker for inflammatory reactions of the skin in the field of skin pathology. By leaving this increase in IMCAM-1 in skin that has been roughened by contact allergens and inflammatory precursors, the skin becomes uncomfortable, such as allergies and hypersensitivities. The skin irritation relieving agent is extremely effective in suppressing the increase in ICAM-1 and brings a comfortable state to the skin. Therefore, human keratinocyte cells were treated with a control (single), 2.0% and 5.0% skin irritation mitigating agent for 24 hours, and then ICAM-1 was measured. The results are shown in FIG.
[0017]
From FIG. 1, the amount of ICAM-1 in the control (alone) is 100, whereas the amount of ICAM-1 in the 2.0% skin irritation mitigating agent is 24, showing 76% inhibition, and 5.0% skin irritation mitigating agent. The amount of ICAM-1 was 15 and was 85% suppression. That is, a very significant decrease in ICAM-1 was observed with respect to human keratinocytes. It has been found that the skin irritation mitigating agent is extremely effective in suppressing the increase in ICAM-1 and brings a comfortable state to the skin.
[0018]
[Experimental example 2] Quantitative test of collagen matrix formation (gelation) by cultured human skin fibroblasts Prepare human fibroblast suspension, collagen solution, and collagen solution mixed with test substance, and place in culture dish Incubation was performed under wet conditions. As a test substance, a 0.03% skin irritation relieving agent and retinoic acid were used, and a test substance not containing the test substance was used as a control. Shrinkage due to collagen matrix formation was compared by measuring the diameter of the matrix.
[0019]
A collagen solution becomes a gel when matrixed in the presence of fibroblasts, and the volume of the solution shrinks. As shown in FIG. 2, it can be seen from this test that the 0.03% skin irritation relieving agent improves collagen matrix formation even at low concentrations. This result shows that it is effective for tissue reconstruction in skin disorders. It also suggests that simultaneous administration with collagen is effective.
[0020]
The creams used in the examples and comparative examples described below were prepared according to the composition shown in the table below. The amount indicates weight percent.
[0021]
