【発明の属する技術分野】
この発明はコラーゲン生成促進剤に関するものであり、とりわけ、有効成分として、オニウム塩と、L−アスコルビン酸又はその塩若しくは誘導体とをそれぞれ含んでなるコラーゲン生成促進剤に関するものである。
【0002】
【従来の技術】
最近、皮膚の老化防止を標榜する、コラーゲンを配合した香粧品が市場を賑わしている。ところが、コラーゲンは、周知のとおり、分子量約100,000ダルトンの高分子物質であることから、表皮から経皮的に適用したのでは、皮下へ浸透する量に限界がある。また、これまで、香粧品へコラーゲンを0.01乃至10質量%配合することが提案されているれども(例えば、特許文献1などを参照)、香粧品へ10質量%にも達する、大量の高分子物質を配合するとなると、使用感も含めて、香粧品の形態ごとに基本処方を丹念に見直し、コラーゲンを比較的大量に配合し得る処方を試行錯誤的に検索しなければならないという問題があった。

皮膚外用剤におけるオニウム塩の配合量としては、皮膚外用剤の使用目的にもよるけれども、通常、0.0001質量%を超え、0.01質量%を超えない範囲、好ましくは、0.0005乃至0.005質量%の範囲で加減する。L−アスコルビン酸類は、通常、0.001質量%を超え、10質量%を超えない範囲、好ましくは、0.005乃至5質量%の範囲で加減する。オニウム塩及びL−アスコルビン酸は、いずれも、上記した範囲を下回って配合すると、所期のコラーゲン生成促進が得られ難くなり、また、上記した範囲を上回って配合しても、配合量に見合ったコラーゲン生成が得られなくなることから、通常、上記した範囲で加減するのが望ましい。

この発明によるコラーゲン生成促進剤を含んでなる皮膚外用剤は、通常の香粧品としての形態である、例えば、クレンジングフォーム、クレンジングクリーム、化粧水、バニシングクリーム、ハイゼニッククリーム、ナリッシングクリーム、エモリエントクリーム、コールドクリーム、乳液、パックなどの基礎化粧品、ファンデーション、ほほ紅、アイライナー、マスカラ、アイシャドー、まゆずみ、おしろいなどの仕上化粧品、ボディクリーム、ボディローション、マッサージクリーム、ボディパウダーなどのボディ化粧品、さらには、浴用剤などの形態に調製することができ、皮膚へ塗布、貼付又は噴霧するか、あるいは、液状に調製した皮膚外用剤へ皮膚を浸漬したり皮膚を洗浄する。皮膚外用剤の形態にもよるけれども、用法としては、通常、例えば、1日当たり1乃至5回の頻度で、1週間当たり1乃至7日間適用する。
【0024】
この発明によるコラーゲン生成促進剤を含んでなる皮膚外用剤は、後述する実験例などからも明らかなように、人をはじめとする哺乳類において、表皮から経皮的に適用することによって、コラーゲンの生成を著明に促進することから、例えば、コラーゲンの欠乏が直接又は間接の要因となる皮膚の不都合、例えば、肌あれ、小じわ、しみ、そばかす、くすみ、かさつき、湿疹、かぶれなどの予防や解消に効果を発揮する。また、一般式1又は一般式2のいずれかで表されるオニウム塩は、L−アスコルビン酸類と組み合わせて用いることによって、生体内においてL−アスコルビン酸類単独では容易に達成できない、高レベルのコラーゲン生成をもたらすことから、コラーゲンの生成促進を目的の一つとする、L−アスコルビン酸類を含有する香粧品などの皮膚外用剤へ配合することによって、皮膚外用剤へ本来配合すべきL−アスコルビン酸類の量を著減することができる実益がある。皮膚外用剤の種類やその使用目的にもよるけれども、この発明のコラーゲン生成促進剤は、一般に、少量配合することによって所期の効果が得られることから、天然のコラーゲンをそのまま配合する場合などとは違って、香粧品などの皮膚外用剤の基本処方を大幅に変更する必要がない。しかも、この発明で用いるオニウム塩及びL−アスコルビン酸類は、いずれも、低分子の物質であって、生体組織に対する親和性も大きいことから、表皮から経皮的に適用しても容易に有効量を皮下へ浸透させることができる。
【0025】
次に、この発明によるコラーゲン生成促進剤のコラーゲン生成促進能につき、実験例に基づいて説明する。
【0026】
【実験例1】
〈生体外におけるコラーゲン生成促進〉
人新生児の包皮に由来する正常線維芽細胞(商品名『NHDF』、倉敷紡績株式会社販売)を20体積%仔ウシ血清を補足したダルベッコ変法イーグル培地(pH7.4)に分散させ、培養プレートへ播種した。その後、常法にしたがって、培地を適宜交換しながら、均一な細胞単層を形成するまで培養した後、培養物に対して、化学式1で表されるピリジニウム塩(「感光素301号」、純度98%以上、株式会社林原生物化学研究所製造)又は化学式2で表されるオキサゾリウム塩(「感光素401号」、純度98%以上、株式会社林原生物化学研究所製造」)のいずれかと、2−O−α−D−グルコピラノシル−L−アスコルビン酸(商品名『アスコルビン酸 2−グルコシド』、純度98%以上、株式会社林原生物化研究所製造、以下、「AA−2G」と略記する。)とを表1に示す濃度にそれぞれ溶解させた上記と同様の培地を添加し、37℃でさらに6日間培養した。
【0027】
培養物から細胞を採取し、常法にしたがってペプシンで処理した後、市販のコラーゲン定量キット(商品名『Sircol Collagen Assay Kit』、フナコシ株式会社販売)を用いて細胞表面の可溶性コラーゲンの量を調べた。併行して、オニウム塩又はAA−2Gのいずれかを省略した以外は上記と同様に処理する4種類の系を別に設け、対照とした。結果を表1に併記する。
【0028】
【表1】
【0029】
表1の結果に見られるとおり、本例の試験に供したオニウム塩は、いずれも、単独では検出し得るレベルのコラーゲンを生成しなかった。また、宮田聡美ら『ナチュラル・メディスンズ』、第56巻、第5号、191乃至194頁(2002年)などにコラーゲンの生成促進作用が報告されているAA−2Gも、単用によるコラーゲンの生成量は6乃至12μg/ウェル程度にすぎなかった。ところが、培地にAA−2Gと化学式1又は化学式2のいずれかで表されるオニウム塩とを添加すると、細胞表面におけるコラーゲンレベルが著増し、コラーゲンレベルがAA−2G単用の場合の3乃至5倍にも達した。
【0030】
これらの実験結果は、一般式1又は一般式2のいずれかで表されるオニウム塩とL−アスコルビン酸類とを組み合わせて生体へ適用すると、後者のL−アスコルビン酸類だけでは達成されない、極めて高レベルのコラーゲン生成がもたらされることを物語っている。なお、固相酵素免疫測定法による数値データは割愛するけれども、化学式1又は化学式2で表されるオニウム塩とAA−2Gとを組み合わせて適用した系の培養上清は、哺乳類において、コラーゲン関連遺伝子の転写を促進することによってコラーゲンの生成を促進すると考えられている形質転換成長因子(TGF−β1)を著量含んでいた。L−アスコルビン酸類は、例えば、林照伸ら『フラグランス・ジャーナル』、第20巻、第2号、32乃至40頁(1992年)に記載されているように、コラーゲンにおけるプロリン残基及びリジン残基の水酸化を触媒する酵素の補助因子としてコラーゲンの生成を促進することが知られている。本例の実験において、著量のTGF−β1が特定の培養上清に検出されたことは、生体へ適用された一般式1又は一般式2で表されるオニウム塩が、L−アスコルビン酸類の存在下において、先ず、TGF−β1の産生を誘発し、次いで、その誘発されたTGF−β1がコラーゲンの生成を誘発する、別のコラーゲン生成機構の存在を示唆している。
【0031】
【実験例2】
〈生体内におけるコラーゲン生成促進〉
一群の成熟白色家兎の背部に2cm前後の切創をつくり、直ちに手術糸で縫合した。その後、2週間に亙って切創部へ化学式1で表されるピリジニウム塩(「感光素301号」、純度98%以上、株式会社林原生物化学研究所製造)又は化学式2で表されるオキサゾリウム塩(「感光素401号」、純度98%以上、株式会社林原生物化学研究所製造)のいずれかと、2−O−α−D−グルコピラノシル−L−アスコルビン酸(商品名『アスコルビン酸 2−グルコシド』、純度98%以上、株式会社林原生物化研究所製造)とを、それぞれ、0.005質量%及び5質量%になるように蒸留水に溶解せしめてなる液状コラーゲン生成促進剤を毎日1回塗布した。併行して、蒸留水のみを塗布する系を設け、対照とした。
【0032】
塗布を開始してから2週間目に、常法にしたがって、切創部位の組織を摘出し、染色した後、顕微鏡により組織検査したところ、この発明によるコラーゲン生成促進剤を塗布した系は、いずれにおいても、対照と比較して、切創部を中心に有意により顕著な新生肉芽組織が増生し、コラーゲンがその随所に浮腫状に染出された。この実験結果は、この発明によるコラーゲン生成促進剤が、生体において、表皮から経皮的に適用して有効であることを物語っている。

BACKGROUND OF THE INVENTION
The present invention relates to a collagen production promoter, and more particularly, to a collagen production promoter comprising an onium salt and L-ascorbic acid or a salt or derivative thereof as active ingredients.
[0002]
[Prior art]
Recently, cosmetics formulated with collagen advocating the prevention of skin aging have become popular in the market. However, since collagen is a polymer substance having a molecular weight of about 100,000 daltons as is well known, there is a limit to the amount that can be percutaneously penetrated when applied percutaneously from the epidermis. In addition, until now, it has been proposed to add 0.01 to 10% by mass of collagen to cosmetics (see, for example, Patent Document 1), but a large amount of cosmetics reaches 10% by mass. When polymer substances are blended, there is a problem that the basic formula must be carefully reviewed for each cosmetic form, including the feeling of use, and a formula that can contain a relatively large amount of collagen must be searched on a trial and error basis. there were.

[0022]
The blending amount of the onium salt in the external preparation for skin depends on the intended use of the external preparation for skin, but usually exceeds 0.0001% by mass and does not exceed 0.01% by mass, preferably 0.0005 to Adjust in the range of 0.005 mass%. L-ascorbic acids are usually adjusted in a range exceeding 0.001% by mass and not exceeding 10% by mass, preferably in a range of 0.005 to 5% by mass. When both the onium salt and L-ascorbic acid are blended below the above range, it is difficult to obtain the desired promotion of collagen production, and even if blended above the above range, the amount is commensurate with the blending amount. In general, it is desirable to adjust the amount within the above-mentioned range since it is impossible to produce collagen.

The external preparation for skin comprising the collagen production promoter according to the present invention is in the form of a normal cosmetic, for example, cleansing foam, cleansing cream, lotion, vanishing cream, hizenic cream, nourishing cream, emollient cream, Basic cosmetics such as cold creams, milky lotions, packs, foundation cosmetics such as foundation, cheeks, eyeliner, mascara, eye shadow, eyebrows, and funny, body cosmetics such as body creams, body lotions, massage creams, body powders, and more Can be prepared in the form of a bath preparation or the like, applied to the skin, applied or sprayed, or immersed in a skin external preparation prepared in a liquid form or washed. Although it depends on the form of the external preparation for skin, it is usually applied, for example, 1 to 5 times per day for 1 to 7 days per week.
[0024]
An external preparation for skin comprising a collagen production promoter according to the present invention is, as will be apparent from experimental examples and the like described later, by producing a collagen by applying it percutaneously from the epidermis in mammals including humans. For example, the prevention or elimination of skin inconveniences caused directly or indirectly by collagen deficiency, such as rough skin, fine lines, spots, freckles, dullness, roughness, eczema, rash, etc. To be effective. Moreover, the onium salt represented by either the general formula 1 or the general formula 2 is used in combination with L-ascorbic acid, so that a high level of collagen production that cannot be easily achieved in vivo by L-ascorbic acid alone. The amount of L-ascorbic acids to be originally added to the skin external preparation by blending it into a skin external preparation such as cosmetics containing L-ascorbic acid, which is one of the purposes for promoting the production of collagen. There is a real benefit that can be markedly reduced. Although it depends on the type of external preparation for skin and the purpose of use, the collagen production promoter of the present invention generally provides the desired effect when blended in a small amount. On the other hand, there is no need to drastically change the basic prescription for external preparations such as cosmetics. Moreover, since both the onium salts and L-ascorbic acids used in the present invention are low molecular weight substances and have a high affinity for living tissues, they are easily effective even when applied transdermally from the epidermis. Can penetrate into the skin.
[0025]
Next, the collagen production promoting ability of the collagen production promoter according to the present invention will be described based on experimental examples.
[0026]
[Experiment 1]
<Promoting collagen production in vitro>
Normal fibroblasts derived from human foreskin (trade name “NHDF”, sold by Kurashiki Boseki Co., Ltd.) are dispersed in Dulbecco's modified Eagle medium (pH 7.4) supplemented with 20% by volume calf serum, and cultured plate Sowing. Thereafter, the cells are cultured until a uniform cell monolayer is formed by appropriately changing the medium according to a conventional method, and then the pyridinium salt represented by the chemical formula 1 (“photosensitive element 301”, purity) 98% or higher, manufactured by Hayashibara Biochemical Laboratories Co., Ltd.) or an oxazolium salt represented by Chemical Formula 2 (“photosensitive element 401”, purity 98% or higher, manufactured by Hayashibara Biochemical Laboratories Co., Ltd.); -O-α-D-glucopyranosyl-L-ascorbic acid (trade name “ascorbic acid 2-glucoside”, purity 98% or more, manufactured by Hayashibara Biochemical Laboratory Co., Ltd., hereinafter abbreviated as “AA-2G”) Were added at the concentrations shown in Table 1 and the same medium as above was added, followed by further culturing at 37 ° C. for 6 days.
[0027]
After collecting cells from the culture and treating with pepsin according to a conventional method, the amount of soluble collagen on the cell surface is examined using a commercially available collagen quantification kit (trade name “Sircol Collagen Assay Kit”, sold by Funakoshi Co., Ltd.). It was. In parallel, four types of systems that were treated in the same manner as above except that either the onium salt or AA-2G was omitted were provided as controls. The results are also shown in Table 1.
[0028]
[Table 1]
[0029]
As can be seen from the results in Table 1, none of the onium salts subjected to the tests of this example produced detectable levels of collagen alone. AA-2G, which has been reported to promote collagen production, such as “Natural Medicines”, Vol. 56, No. 5, pages 191 to 194 (2002), is also used by Ami Miyata et al. The amount produced was only about 6 to 12 μg / well. However, when AA-2G and an onium salt represented by either Chemical Formula 1 or Chemical Formula 2 are added to the medium, the collagen level on the cell surface increases significantly, and the collagen level is 3 to 5 in the case of using AA-2G alone. Doubled.
[0030]
When these experimental results are applied to a living body in combination with an onium salt represented by either general formula 1 or general formula 2 and L-ascorbic acid, the latter L-ascorbic acid is not achieved by the very high level. It tells us that collagen production is brought about. Although the numerical data obtained by the solid-phase enzyme immunoassay is omitted, the culture supernatant of the system applied by combining the onium salt represented by Chemical Formula 1 or Chemical Formula 2 and AA-2G is a collagen-related gene in mammals. It contained a significant amount of transforming growth factor (TGF-β1), which is believed to promote collagen production by promoting the transcription of. L-ascorbic acids are exemplified by, for example, Hayashi Terunobu et al., “Fragrance Journal”, Vol. 20, No. 2, pages 32 to 40 (1992). It is known to promote collagen production as a cofactor for enzymes that catalyze hydroxylation of groups. In the experiment of this example, a significant amount of TGF-β1 was detected in the specific culture supernatant because the onium salt represented by the general formula 1 or 2 applied to the living body was an L-ascorbic acid compound. In the presence, it suggests the existence of another collagen production mechanism that first induces the production of TGF-β1, and then the induced TGF-β1 induces the production of collagen.
[0031]
[Experimental example 2]
<Promoting collagen production in vivo>
A cut of about 2 cm was made on the back of a group of mature white rabbits and immediately sutured with a surgical thread. Then, for two weeks, the pyridinium salt represented by Chemical Formula 1 ("Photosensitive Element 301", purity 98% or more, manufactured by Hayashibara Biochemical Laboratories Co., Ltd.) or the oxazolium salt represented by Chemical Formula 2 (“Photosensitive element 401”, purity 98% or more, manufactured by Hayashibara Biochemical Laboratories Co., Ltd.) and 2-O-α-D-glucopyranosyl-L-ascorbic acid (trade name “ascorbic acid 2-glucoside”) , A purity of 98% or more, manufactured by Hayashibara Biochemical Laboratories Co., Ltd.) is applied once a day to a liquid collagen production promoter prepared by dissolving 0.005% by mass and 5% by mass in distilled water. did. In parallel, a system for applying only distilled water was provided as a control.
[0032]
Two weeks after the start of application, the tissue of the incision site was excised and stained according to a conventional method, and the tissue was examined with a microscope. In comparison with the control, significantly more prominent new granulation tissue grew mainly in the incised part, and collagen was stained in edema everywhere. This experimental result shows that the collagen production promoter according to the present invention is effective when applied percutaneously from the epidermis in a living body.
[0033]
