Description

【0001】
【発明の属する技術分野】
本発明は、養毛料に関し、更に詳しくは、育毛、養毛、脱毛予防効果に優れ、エタノール、含水エタノール等に対する溶解性及び使用感に優れた養毛料に関する。本発明の養毛料は、具体的には、医薬品、医薬部外品又は化粧品の分野において利用される。
【0002】
【従来の技術】
一般的に、脱毛症は血行の不全、毛母細胞活性の低下や性ホルモンのアンバランス等の様々な要因が複雑に絡み合って生じていると考えられている。特に現代社会は高齢化社会、ストレス社会と言われるように、様々な原因によって脱毛の危機にさらされる機会が多くなっている。しかし、脱毛の発生機作やメカニズムが未だ十分に解明されていないのが現状である。従来の養毛料には養毛、育毛効果が期待される薬効成分として、例えば、トウガラシチンキ、センブリエキス、朝鮮ニンジンエキス、ニコチン酸誘導体等の頭皮の血行促進物質、セファランチン等の皮膚機能亢進物質、アセチルコリン誘導体等の血管拡張剤、エストラジオール等の女性ホルモン剤、パントテン酸誘導体等のメラニン合成触媒剤、サリチル酸、レゾルシン等の角質溶解剤、グリチルレチン酸、シコンエキス等の抗炎症剤が配合され、脱毛の予防や治療に用いられている。しかしながら、これらの薬剤は、場合によっては皮膚刺激を引き起こしたりするため、配合量に制限があったり、十分な育毛、脱毛防止、ふけ防止等の効果が発現する効果が充分でなく、その為、より効果的な養毛料が強く要望されている。
【0003】
本発明者等は、養毛料に配合して有効な効果を示す物質として、特開2001−192322号公報に開示されているファルネシル酢酸ゲラニオール(ゲファルナート)を見出した。本物質は、ファルネシル酢酸(5,9,13−trimethyl−4,8,12−tetradecatrienoic acid)とゲラニオール(3,7−dimethyl−2,6−octadienol)のエステルであり、淡黄色〜黄色の澄明油状物質である。従来、医療用製剤原料として用いられており、胃潰瘍、十二指腸潰瘍に効果があり、粘液中のヘキソサミン量を増加させ粘膜抵抗性を増強すると共にその修復を促進し、粘膜の血流量を増加させる等の効果があることが知られている物質である。
【0004】
しかしながら、上記ファルネシル酢酸ゲラニオールはエタノールや含水エタノールに溶解せず、また油性感が強いためにべたつきなどの使用感触に問題を有しており、製剤化に当たっては特段の工夫を要し、改良の余地があった。養毛・育毛を目的とした養毛料においては、透明液状の製品が一般的であり、また、透明液状であることは有効成分の経皮吸収性を高めるためにも必要である。しかし、使用する有効成分の化学構造によりエタノールや含水エタノール等の溶剤に溶解せず、白濁或いは沈殿を生じる場合は、透明液状とならないため育毛効果の低下や経皮透過性の低下が懸念される。従って、養毛料に使用される有効成分は、育毛、養毛効果はもちろんのこと、エタノール、含水エタノール等に対する溶解性、更に使用感のいずれにも優れていることが望まれている。
【0005】
【発明が解決しようとする課題】
本発明の目的とするところは、育毛、養毛、脱毛予防効果に優れ、エタノール、含水エタノール等の溶媒に対する溶解性に優れている上、使用感も良好な養毛料を提供することにある。
【0006】
【課題を解決するための手段】
本発明者等は、上記目的を達成するために、鋭意研究を重ねた結果、ファルネシル酢酸と多価アルコールより合成されるファルネシル酢酸誘導体が、育毛、養毛、脱毛予防効果に優れ、エタノール、含水エタノール等の溶媒に対する溶解性に優れている上、使用感も良好であることを見出して本発明を完成するに至った。
【0007】
即ち、本発明は、下記一般式(1)〜(4)いずれかで表されるファルネシル酢酸誘導体から選ばれる少なくとも一種以上を含有することを特徴とする養毛料である。

【発明の実施の形態】
以下、本発明の実施形態について詳述する。
【0013】
本発明に用いる上記一般式(1)〜(4)いずれかで表わされるファルネシル酢酸誘導体は、ファルネシル酢酸(5,9,13−trimethyl−4,8,12−tetradecatrienoic acid)と多価アルコールとのエステル化合物である。ファルネシル酢酸をエステル誘導体化する多価アルコールとしては、エチレングリコール及びエチレングリコールの脱水縮合物であるジエチレングリコール,トリエチレングリコール,ポリエチレングリコール、プロピレングリコール及びプロピレングリコールの脱水縮合物であるジプロピレングリコール,ポリプロピレングリコール、グリセリン及びグリセリンの脱水縮合物であるジグリセリン,ポリグリセリン、3−メチル−1,3−ブタンジオール、イソプレングリコール、1,3−ブチレングリコール等が挙げられる。
【0014】
上記一般式(1)中、mで示される整数は1〜5であり、上記一般式(2)中、nで示される整数は1〜5であり、上記一般式(3)中、pで示される整数は1〜5であり、上記一般式(4)中、Rは水素又は炭素数1〜3の直鎖の飽和又は不飽和炭化水素基である。また、養毛効果の点からm、n及びpは1〜2がより好ましい。m、n、pが1未満の場合、皮膚刺激性を生じる場合があり好ましくなく、またm、n、pが5を超えると分子量が大きくなり、経皮浸透性が劣るために養毛効果が見られず、好ましくない。また、これらのファルネシル酢酸誘導体は公知のエステル化の方法でファルネシル酢酸と各種多価アルコールから容易に合成することができるし、また、通常市販されているものをそのまま、或いは蒸留等によって精製した後に使用することも可能である。
【0015】
これらのファルネシル酢酸誘導体は、それぞれ単独で用いることができるし、また2種以上組み合わせて用いることができる。また、これらのファルネシル酢酸誘導体の養毛料への配合量は、好ましくは、0.01〜10.0質量%(以下、%とする)であり、更に好ましくは0.05〜5.0%である。ファルネシル酢酸誘導体の配合量が0.01%未満では本発明の目的とする効果が十分に得られない場合があり、配合量が10.0%を越えても、その増加分に見合った効果の向上は望めない場合があり、また使用時の感触が悪くなり易く、製剤化上支障をきたす傾向が顕著となり好ましくない。
【0016】
また、本発明においては、更に血流促進剤を配合し、ファルネシル酢酸誘導体と血流促進剤とを併用することによって、より発毛促進効果を増大させることができる。血流促進剤は、それを皮膚上に塗布すると、血流が促進され、かつ外用剤の配合成分として安全性上問題がない限り、特に限定されるものではなく、その作用機序も問われるべきものではない。具体的には、ニコチン酸ベンジル,ニコチン酸トコフェロール,ニコチン酸β−ブトキシエチル,ニコチン酸アミド等のニコチン酸誘導体、ミノキシジル並びにその誘導体及びその類縁体、セファランチン、ビタミンE及びその誘導体、γ−オリザノール、アルコキシカルボニルピリジンN−オキシド、塩化カプロニウム、アセチルコリン及びその誘導体、末梢血行障害治療薬(プロスタグランジン、カルバシクリン、パパベリン、シクランデレート、シンナリジン、ナイリドリン、カリクレイン)、カルシウム拮抗剤、ホスホジエステラーゼ阻害剤、亜硝酸化合物、アデノシン作用増強性血管拡張薬、ヒドラジン等の従来から血流促進剤として使用されているものを適宜選択することができる。また、これらの血流促進剤を単独で本発明の養毛料に配合することも可能であるが、2種以上を組み合わせて配合することも可能である。本発明の養毛料においては、上記の血流促進剤は、養毛料全体に対して0.001〜5.0%の範囲で配合されるのが好ましく、同0.01〜2.0%の範囲で配合されるのが特に好ましい。血流促進剤の配合量が養毛料全体に対して5.0%を超えると、皮膚刺激等が伴う等、安全性の側面から問題が生じる恐れがあり好ましくない。
【0017】
本発明の養毛料は、種々の形態で用いることができ、例えば、ヘアートニック、ヘアーローション、ヘアークリーム、シャンプー、リンス、ヘアーフォーム、ヘアージェル、エアゾール等の直接頭皮に塗布する剤形に配合し、常法に従い製造することができる。
【0018】
また、本発明の養毛料には、前記の各成分に加えて必要に応じて、かつ本発明の効果を損なわない範囲において、化粧品、医薬部外品、医薬品等において一般的に用いられる各種の成分、例えば、油分、保湿剤、増粘剤、色素、香料、殺菌剤、防腐剤、紫外線吸収剤、溶剤、水、角質溶解剤、抗炎症剤、抗アンドロゲン剤、養毛剤、抗酸化剤、清涼剤、生薬抽出物やビタミン類等を適宜配合することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a hair restorer, and more particularly, to a hair restorer which has an excellent hair-growth, hair-growth, and hair loss-preventing effect, and is excellent in solubility in ethanol, aqueous ethanol, and the like, and in use. The hair restorer of the present invention is specifically used in the fields of pharmaceuticals, quasi-drugs, and cosmetics.
[0002]
[Prior art]
In general, alopecia is considered to be caused by various factors such as insufficiency of blood circulation, decreased hair matrix activity, and imbalance of sex hormones. Particularly in modern society, there are many opportunities to be exposed to hair loss due to various causes, such as an aging society and a stressed society. However, at present, the mechanism and mechanism of hair loss has not been sufficiently elucidated. Conventional hair restorer hair growth, as a medicinal ingredient expected hair growth effect, for example, pepper tincture, assembly extract, Korean ginseng extract, scalp blood circulation promoting substances such as nicotinic acid derivatives, skin function enhancing substances such as cepharanthin, Contains vasodilators such as acetylcholine derivatives, female hormones such as estradiol, melanin synthesis catalysts such as pantothenic acid derivatives, keratolytic agents such as salicylic acid and resorcin, anti-inflammatory agents such as glycyrrhetinic acid and sicon extract to prevent hair loss. And is used for treatment. However, these drugs may cause skin irritation, depending on the case, there is a limitation on the amount of compounding, sufficient hair growth, hair loss prevention, effects such as anti-dandruff are not sufficiently effective, There is a strong demand for more effective hair restorations.
[0003]
The present inventors have found geraniol farnesyl acetate (gefarnate) disclosed in Japanese Patent Application Laid-Open No. 2001-192322 as a substance which shows an effective effect when incorporated into a hair restoration. This substance is an ester of farnesyl acetic acid (5,9,13-trimethyl-4,8,12-tetradecatrienoic acid) and geraniol (3,7-dimethyl-2,6-octadienol), and is a pale yellow to yellow clear liquid. It is an oily substance. Conventionally, it is used as a raw material for medical preparations, is effective for gastric ulcer and duodenal ulcer, increases the amount of hexosamine in mucus, enhances mucosal resistance, promotes its repair, and increases blood flow of mucous membrane, etc. It is a substance that is known to be effective.
[0004]
However, the above geraniol farnesyl acetate does not dissolve in ethanol or hydrous ethanol, and has a problem in use feeling such as stickiness due to a strong oily feeling, so that special preparation is required for formulation, and there is room for improvement. was there. In hair restorations for the purpose of hair growth and hair growth, transparent liquid products are generally used, and transparent liquids are also necessary to enhance the transdermal absorbability of the active ingredient. However, depending on the chemical structure of the active ingredient used, if it does not dissolve in a solvent such as ethanol or hydrated ethanol and causes cloudiness or precipitation, it does not become a transparent liquid, so there is a concern that the hair growth effect is reduced and the transdermal permeability is reduced. . Therefore, it is desired that the active ingredient used in the hair restorer is excellent in not only the hair restoring and hair restoring effects but also the solubility in ethanol, ethanol containing water and the like, and further, the feeling of use.
[0005]

[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail.
[0013]
The farnesyl acetic acid derivative represented by any of the above general formulas (1) to (4) used in the present invention is a mixture of farnesyl acetic acid (5,9,13-trimethyl-4,8,12-tetradecatrienoic acid) and a polyhydric alcohol. It is an ester compound. Examples of the polyhydric alcohol for derivatizing farnesyl acetic acid as an ester include diethylene glycol, triethylene glycol, which is a dehydrated condensate of ethylene glycol, dipropylene glycol, which is a dehydrated condensate of propylene glycol and propylene glycol, and polypropylene glycol. , Glycerin and diglycerin which is a dehydration condensate of glycerin, polyglycerin, 3-methyl-1,3-butanediol, isoprene glycol, 1,3-butylene glycol and the like.
[0014]
In the general formula (1), the integer represented by m is 1 to 5, in the general formula (2), the integer represented by n is 1 to 5, and in the general formula (3), p is The integers shown are 1 to 5, and in the above general formula (4), R is hydrogen or a linear saturated or unsaturated hydrocarbon group having 1 to 3 carbon atoms. In addition, from the viewpoint of the hair growth effect, m, n and p are more preferably 1 to 2. When m, n, and p are less than 1, skin irritation may occur, which is not preferable. When m, n, and p are more than 5, the molecular weight increases and the percutaneous permeability is inferior, so that the hair growth effect is reduced. Not seen, not preferred. Further, these farnesyl acetic acid derivatives can be easily synthesized from farnesyl acetic acid and various polyhydric alcohols by a known esterification method. It is also possible to use.
[0015]
These farnesyl acetic acid derivatives can be used alone or in combination of two or more. Further, the compounding amount of these farnesyl acetic acid derivatives in the hair growth agent is preferably 0.01 to 10.0% by mass (hereinafter, referred to as%), and more preferably 0.05 to 5.0%. is there. If the blending amount of the farnesyl acetic acid derivative is less than 0.01%, the intended effect of the present invention may not be sufficiently obtained, and even if the blending amount exceeds 10.0%, the effect corresponding to the increase may not be obtained. In some cases, improvement cannot be expected, and the feeling during use is liable to deteriorate, and the tendency to hinder preparation is notable, which is not preferable.
[0016]
Further, in the present invention, the hair growth promoting effect can be further increased by further blending a blood flow promoter and using the farnesyl acetic acid derivative together with the blood flow promoter. The blood flow enhancer is not particularly limited as long as the blood flow enhancer is applied on the skin, as long as the blood flow is promoted and there is no safety problem as a component of the external preparation, and its mechanism of action is also questioned. It should not be. Specifically, nicotinic acid derivatives such as benzyl nicotinate, tocopherol nicotinate, β-butoxyethyl nicotinate, nicotinamide, minoxidil and its derivatives and analogs, cepharanthin, vitamin E and its derivatives, γ-oryzanol, Alkoxycarbonylpyridine N-oxide, capronium chloride, acetylcholine and derivatives thereof, therapeutic agents for peripheral blood circulation disorders (prostaglandins, carbcycline, papaverine, cyclandulate, cinnarizine, nylidrin, kallikrein), calcium antagonists, phosphodiesterase inhibitors, nitrite Compounds, adenosine action-enhancing vasodilators, hydrazine and the like which have been conventionally used as a blood flow promoting agent can be appropriately selected. In addition, these blood flow promoters can be used alone in the hair restorer of the present invention, but can also be used in combination of two or more. In the hair restorer of the present invention, the blood flow enhancer is preferably blended in a range of 0.001 to 5.0% based on the entire hair restorer, and 0.01 to 2.0% of the same. It is particularly preferred to be blended in the range. If the amount of the blood flow enhancer exceeds 5.0% based on the total amount of the hair growth agent, problems such as skin irritation may occur from the safety aspect, which is not preferable.
[0017]
The hair restorer of the present invention can be used in various forms.For example, it is incorporated into a dosage form directly applied to the scalp such as hair tonic, hair lotion, hair cream, shampoo, rinse, hair foam, hair gel, aerosol and the like. It can be manufactured according to a conventional method.
[0018]
In addition, the hair restorer of the present invention includes various components generally used in cosmetics, quasi-drugs, pharmaceuticals, and the like, as needed, in addition to the above-described components, and within a range that does not impair the effects of the present invention. Ingredients, for example, oils, humectants, thickeners, pigments, fragrances, bactericides, preservatives, ultraviolet absorbers, solvents, water, keratolytics, anti-inflammatory agents, anti-androgens, hair restorers, antioxidants, cool Agents, crude drug extracts, vitamins, and the like can be appropriately blended.
