Description

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。   The present invention relates to a hair nourishing agent, and more particularly, to a hair nourishing agent excellent in hair growth, hair nourishing and hair loss prevention effects, and excellent in solubility and use feeling in ethanol, hydrous ethanol and the like. Specifically, the hair nourishing agent of the present invention is used in the field of pharmaceuticals, quasi drugs or cosmetics.

一般的に、脱毛症は血行の不全、毛母細胞並びに毛乳頭細胞の活性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。   In general, alopecia is considered to be caused by complex intertwining of various factors such as blood circulation failure, decreased activity of hair matrix cells and dermal papilla cells, and imbalance of sex hormones. In particular, the modern society is exposed to the risk of hair loss due to various causes, as it is said to be an aging society and a stress society. However, the mechanism and mechanism of hair loss have not been fully elucidated yet. Conventional hair nourishing agents are expected to have hair growth and hair-growth effects, for example, chili pepper tincture, assembly extract, ginseng extract, nicotinic acid derivative and other scalp blood circulation promoting substances, cephalanthin and other skin function enhancing substances, Prevents hair loss by combining vasodilators such as acetylcholine derivatives, female hormone agents such as estradiol, melanin synthesis catalyst agents such as pantothenic acid derivatives, keratolytic agents such as salicylic acid and resorcin, and anti-inflammatory agents such as glycyrrhetinic acid and sicon extract. It is used for treatment. However, these drugs may cause skin irritation in some cases, so the amount of blending is limited, or the effect of sufficient hair growth, hair loss prevention, anti-dandruff etc. is not sufficient, therefore, There is a strong demand for more effective hair nourishment.

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、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(特許文献1参照)。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。   The present inventors have discovered farnesyl geraniol acetate (gefarnate) as a substance that shows an effective effect when blended in a hair nourishing agent (see Patent Document 1). 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), light yellow to yellow clear It is an oily substance. It has been used as a raw material for pharmaceutical preparations and is effective for gastric and duodenal ulcers. It increases hexosamine in mucus, enhances mucosal resistance, promotes its repair, increases mucosal blood flow, etc. It is a substance known to have the effect of.

しかしながら、上記ゲファルナート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(特許文献2〜4参照)。   However, the above-mentioned gefarnate does not dissolve in ethanol or hydrous ethanol, and has a problem of feeling of use such as stickiness due to its strong oily feeling, so special preparation is required for formulation and there is room for improvement. It was. Transparent hair products are common in hair nourishing agents for the purpose of hair nourishment and hair growth, and it is necessary to enhance the transdermal absorbability of the active ingredient as well. However, depending on the chemical structure of the active ingredient used, if it does not dissolve in a solvent such as ethanol or hydrous ethanol and causes white turbidity or precipitation, it does not become a transparent liquid, so there is a concern that the hair-growth effect and the transdermal permeability may be reduced . Therefore, it is desired that the active ingredient used in the hair nourishing agent is excellent in both hair growth and hair nourishing effect, solubility in ethanol, hydrous ethanol, etc., and also in the feeling of use (patent document) 2-4).

一方で、ゲラニルゲラニルアルコール等のポリプレニルアルコール類にも育毛活性があることが報告されているが(特許文献5参照)、その効果は十分ではなかった。

On the other hand, polyprenyl alcohols such as geranylgeranyl alcohol have also been reported to have hair growth activity (see Patent Document 5), but the effect was not sufficient.

(但し、式中Rは炭素数1〜7の直鎖又は分岐鎖状の、飽和又は不飽和炭化水素基を示す)で表される脂肪酸ゲラニオールエステルの少なくとも1種以上を配合することを特徴とする養毛料。 (Wherein R represents a linear or branched, saturated or unsaturated hydrocarbon group having 1 to 7 carbon atoms), and is characterized by blending at least one fatty acid geraniol ester represented by Hair nourishing to do.

本発明は、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ができる。   INDUSTRIAL APPLICABILITY The present invention can provide a hair nourishing agent that is excellent in hair growth, hair nourishing, and hair loss prevention effects, has excellent solubility in solvents such as ethanol and hydrous ethanol, and also has a good feeling in use.

以下、本発明の実施の形態を詳述する。本発明で用いられる脂肪酸ゲラニオールエステルは、ゲラニオールと、炭素原子数が2〜8の脂肪酸又はその誘導体(酸クロリド、酸無水物等)とのエステル合成反応により容易に合成することができる。前記脂肪酸は直鎖型でも分岐型でも、また飽和でも不飽和でもいずれでも構わない。また、試薬として、あるいは香料物質として市販されているものも多くあり、それらをそのまま、又は蒸留等により精製した後に使用することもできる。   Hereinafter, embodiments of the present invention will be described in detail. The fatty acid geraniol ester used in the present invention can be easily synthesized by an ester synthesis reaction between geraniol and a fatty acid having 2 to 8 carbon atoms or a derivative thereof (acid chloride, acid anhydride, etc.). The fatty acid may be linear or branched, and may be either saturated or unsaturated. Many of them are commercially available as reagents or fragrance substances, and they can be used as they are or after being purified by distillation or the like.

本発明で用いられる脂肪酸ゲラニオールエステルには立体異性体が存在するが、全ての異性体及びそれらの混合物のいずれでも育毛効果及び脱毛予防効果に優れる。本発明で用いられる脂肪酸ゲラニオールエステルの一例としては、2−エチルヘキサン酸ゲラニル、2,3−ジメチル−2−ブテン酸ゲラニル、3−メチルブタン酸ゲラニルを挙げることができる。   The fatty acid geraniol ester used in the present invention has stereoisomers, and all of the isomers and mixtures thereof are excellent in hair growth effect and hair loss prevention effect. Examples of the fatty acid geraniol ester used in the present invention include geranyl 2-ethylhexanoate, geranyl 2,3-dimethyl-2-butenoate, and geranyl 3-methylbutanoate.

本発明に用いる物質の養毛料への配合量は、好ましくは、0.01〜10.0質量%(以下、単に%と表記する)であり、更に好ましくは0.05〜5.0%である。脂肪酸ゲラニオールエステルの配合量が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、製剤化の上で支障をきたす傾向が顕著となり好ましくない。   The amount of the substance used in the present invention to the hair nourishing agent is preferably 0.01 to 10.0% by mass (hereinafter simply referred to as%), more preferably 0.05 to 5.0%. is there. If the blending amount of the fatty acid geraniol ester is less than 0.01%, the intended effect of the present invention may not be sufficiently obtained. Even if the blending amount exceeds 10.0%, the effect commensurate with the increase amount. In some cases, improvement cannot be expected, and the feeling during use tends to be poor, and the tendency to cause troubles in preparation is remarkable.

また、本発明においては、更に血流促進剤を配合し、脂肪酸ゲラニオールエステル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。   Moreover, in this invention, the hair growth promotion effect can be increased more by mix | blending a blood flow promoter and using fatty acid geraniol ester and a blood flow promoter together. The blood flow promoting agent is not particularly limited as long as the blood flow is promoted when applied to the skin, and there is no safety problem as a compounding component of the external preparation, the action mechanism is also questioned. It shouldn't be. Specifically, nicotinic acid derivatives such as benzyl nicotinate, tocopherol nicotinate, β-butoxyethyl nicotinate, and nicotinamide, minoxidil and derivatives thereof, cephalanthin, vitamin E and derivatives thereof, γ-oryzanol, Alkoxycarbonylpyridine N-oxide, capronium chloride, acetylcholine and its derivatives, peripheral hematologic disorders (prostaglandins, carbacyclin, papaverine, cyclandrate, cinnarizine, nyridrin, kallikrein), calcium antagonists, phosphodiesterase inhibitors, nitrous acid A compound, an adenosine action-enhancing vasodilator, hydrazine and the like conventionally used as a blood flow promoter can be appropriately selected. Moreover, although these blood flow promoters can be blended alone in the hair nourishing agent of the present invention, they can be blended in combination of two or more. In the hair nourishing agent of the present invention, the blood flow promoter is preferably blended in the range of 0.001 to 5.0% with respect to the entire hair nourishing agent, and in the range of 0.01 to 2.0%. It is particularly preferred to be blended with If the blending amount of the blood flow promoter exceeds 5.0% with respect to the whole hair nourishing agent, it may cause problems from the viewpoint of safety such as skin irritation and the like.

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や頭髪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。   The hair nourishing agent of the present invention can be used in various forms, for example, hair tonic, hair lotion, hair cream, shampoo, rinse, hair foam, hair gel, aerosol, etc. It can mix | blend and it can manufacture in accordance with a conventional method.

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。   In addition to the above-mentioned components, the hair nourishment of the present invention is variously used in cosmetics, quasi-drugs, pharmaceuticals, etc. as necessary and within the range not impairing the effects of the present invention. Ingredients such as oils, moisturizers, thickeners, dyes, fragrances, bactericides, preservatives, UV absorbers, solvents, water, keratolytic agents, anti-inflammatory agents, antiandrogens, hair nourishing agents, antioxidants, refreshing Agents, herbal extracts, vitamins and the like can be appropriately blended.
