Description

【0001】
【発明の属する技術分野】本発明は、人体の頭皮に存在する常在真菌の増殖を抑制によりふけを抑制する、ふけ症の予防剤または治療剤、およびそれを含有する毛髪用化粧品に関するものである。
【0002】
【従来の技術】頭皮には、ニキビの原因となるアクネ桿菌のように、正常な皮膚に存在する皮膚常在菌が生息している。同じように皮膚常在真菌である、ふけ原因菌のマラセチア属フルフル(Malassezia furfur)も生息している。ふけの発生は、脂分の好きな皮膚常在真菌が大きく関与しており、皮脂腺が多く皮脂量も多い頭皮は住み易く増殖するのに絶好の住処となっている。ふけは、新陳代謝によって古くなった角質がはがれ落ちたもので、誰にでも生理的に発生する。しかし、ふけの量が異常に多い場合をふけ症といい、放っておくとかゆみを伴い、爪でかいたりし、頭皮に炎症を起こす場合もある。また、ふけ症には、パラパラ落ちる乾性とベタベタした湿性があり、一般に、ふけ症の多くは皮脂の分泌が過剰な湿性が多いとされている。その多くは、脂漏性皮膚炎の先行型または軽症型と考えられており、女性よりも男性に多く発生すると言われている。このように、皮脂の多い頭皮に、ふけ原因菌のマラセチア属フルフル(Malassezia furfur)が増殖および活性増大することにより、ふけやかゆみを悪化させる要因であることが知られている。更に、フケの発生は、脱毛の原因としても知られている。
【0003】
その対策として従来、これらの原因菌に対して抗菌、静菌作用のあるジンクピリチオンやオクトピロックス、ピロクトンオリミンなどが配合されたシャンプー剤などで洗髪すると効果的とされている。しかしながら、ジンクピリチオンは国立環境研究所の調べで、環境ホルモンの疑いがあると発表されており、今後の動向が注目されている。
【0004】
また、マラセチア属フルフル(Malassezia furfur)は、脂漏性皮膚炎の原因となることや、皮膚疾患である癜風の原因であることも知られている。
【0005】
そこで、上記問題を解決するために、天然抽出物を用いた抗菌剤がいくつか提案されている。例えば、特許文献1では、銀杏内種皮抽出物を有効成分として含有させた抗菌性組成物が、また、特許文献2では、有効成分としてラン科植物のエビネ属またはガンゼキラン属の1種以上を含有する頭皮への抗フケ菌効果、血行促進効果、止痒効果および頭髪への発毛効果が、特許文献3では、海藻原料、例えばワカメ、コンブ、ホンダワラなどの褐藻類を灰化することにより得られる海藻灰、あるいは、その抽出液を有効成分とする抗ふけ菌剤、さらに特許文献4では、シトラス系果実の果皮から得られるクマリン類縁体混合物、とくにシトラスコールドプレスオイルから得られるクマリン類縁体混合物を有効成分とする抗菌剤がそれぞれ提案されている。
【0006】
しかしながら、こうした天然由来の抗菌剤は、添加される対象の香りに影響を及ぼすなどの問題を抱えている。
【0007】
一方、一部のラクトンが特定のグラム陽性菌に対して増殖抑制能を示すことは、特許文献5および6などに報告されているが、皮膚常在真菌であるふけ原因菌のマラセチア属フルフル(Malassezia furfur)に対する抗菌性については何ら提案されていない。また、洗髪用化粧品、育毛剤、毛髪仕上げ用化粧品剤、パーマネントウエーブ用剤、染毛剤およびヘアブリーチに快い香りを与える目的で香料化合物が使用されているものの、これら化合物の皮膚常在真菌に対する抗菌性については明記されていない。

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prophylactic or therapeutic agent for dandruff, which suppresses dandruff by suppressing the growth of resident fungi present on the scalp of the human body, and a cosmetic for hair containing the same. is there.
[0002]
2. Description of the Related Art On the scalp, there are indigenous bacteria existing on normal skin, such as acne bacilli, which cause acne. Similarly, the dandruff fungus Malassezia furfur, which is a fungus resident on the skin, also inhabits. The occurrence of dandruff is largely related to skin-resident fungi that like fat, and the scalp, which has a large amount of sebaceous glands and a large amount of sebum, is a great place to live and proliferate. Dandruff is the keratin that has become old due to metabolism and has fallen off. However, when the amount of dandruff is abnormally large, it is called dandruff, and if left unchecked, itching may occur, and the scalp may become irritated with nails. In addition, dandruff has dryness that falls down and sticky wetness. In general, many dandruffs are said to be excessively moist with excessive secretion of sebum. Many of them are considered predecessor or mild forms of seborrheic dermatitis and are said to occur more often in men than in women. As described above, it is known that the dandruff-causing bacterium Malassezia furfur proliferates and increases in activity on the scalp with a large amount of sebum, which is a factor that worsens dandruff and itch. Furthermore, the occurrence of dandruff is also known as a cause of hair loss.
[0003]
As a countermeasure, it has been considered effective to wash the hair with a shampoo containing zinc pyrithione, octopirox, pyrocton olimine, etc., which have antibacterial and bacteriostatic action against these causative bacteria. However, zinc pyrithione has been shown to be suspected of being an endocrine disruptor according to a survey by the National Institute for Environmental Studies, and future trends are attracting attention.
[0004]
It is also known that Malassezia furfur is a cause of seborrheic dermatitis and a cause of dermatitis versicolor.
[0005]
Therefore, in order to solve the above problems, some antibacterial agents using natural extracts have been proposed. For example, in Patent Document 1, an antibacterial composition containing a ginkgo inner seed extract as an active ingredient, and in Patent Document 2, at least one species of the genus Ebine or Ganzechilan of an orchid plant is contained as an active ingredient. In Patent Document 3, the anti-dandruff effect on the scalp, the blood circulation promoting effect, the antipruritic effect and the hair growth effect on the hair can be obtained by incineration of a seaweed raw material, for example, brown algae such as seaweed, kelp, and honda straw. Seaweed ash, or an anti-dandruff agent containing an extract thereof as an active ingredient, and further, in Patent Document 4, a coumarin analog mixture obtained from the citrus fruit pericarp, particularly a coumarin analog mixture obtained from citrus cold pressed oil Have been proposed as active ingredients.
[0006]
However, such naturally occurring antibacterial agents have problems such as affecting the scent of the target to be added.
[0007]
On the other hand, it has been reported in Patent Documents 5 and 6 that some lactones exhibit growth inhibitory activity against specific Gram-positive bacteria, but the dandruff-causing bacterium Malassezia sp. No antimicrobial activity against Malassezia furfur has been proposed. In addition, although fragrance compounds are used for the purpose of imparting a pleasant scent to hair wash cosmetics, hair restorer, hair finish cosmetic agent, permanent wave agent, hair dye and hair bleach, these compounds are effective against skin-resident fungi. No antimicrobial properties are specified.
