Description

【0001】
【発明の属する技術分野】
本発明は、発毛抑制皮膚外用剤に関し、詳しくは、特定の植物抽出物を含有することを特徴とし、足や腕等の発毛を抑制し、毛再生の遅延効果を有する発毛抑制皮膚外用剤に関する。
【0002】
【従来の技術】
一般に体毛、特にムダ毛といわれている毛を処理する場合、大きく分けると剃毛、脱毛、除毛の3つの方法が行われている。すなわち、カミソリによる剃毛、脱毛テープやワックス等の物理的な力による脱毛及び化学処理による除毛方法が用いられている。脱毛については上記の方法の他に、エステティックサロン等では高周波装置を用いる場合もある。また、男性に特有の髭の処理は殆どがカミソリまたは電気カミソリによる剃毛である。そして、これらムダ毛の処理及び髭剃りの後には、皮膚に潤いを与えたり、ほてりを静めることを目的として化粧水やクリーム等を塗布し、肌を整えることが任意に行われていた。特に髭剃りの後に用いる専用化粧料は、男性化粧品の中では非常に一般的な化粧料の一つである。
【0003】
しかしながら、ムダ毛の処理は次に挙げるような欠点を有している。すなわち剃毛については皮膚に微小な傷が多数生じること、脱毛については処理に技術を要し痛みが伴う他、高周波装置を用いる場合は非常に高価であること、また除毛については化学物質により毛を溶解することから皮膚刺激を伴う場合があること等である。髭剃りについてもムダ毛の処理同様、カミソリによる微小な傷が生じ、またカミソリ負けのような皮膚の炎症が起こることもある。更に、剃毛・除毛は皮膚表面部の毛を除去したにすぎず、脱毛しても時間経過と共に、ムダ毛が再生するため、上記の処理を繰り返すことになる。特に髭に関しては、非常に成長速度が速いことから、人によっては一日に2回から3回髭剃りを行わなくてはならない。また、ムダ毛の処理は、毛成長に対する刺激作用が強いため、成長速度を高めたり、休止期毛を活性化させるという問題がある。従って、皮膚に対する負担が大きいことや、処理自体の手間や経費の問題があることから処理頻度の減少化が強く望まれていた。
【0004】
このような背景から、例えば、イチハツ、オノニス、ダイズ等の植物抽出物を塗布することによって、発毛抑制を行う化粧料(特許文献1)や、アジサイ、アマチャ等の植物抽出物を含有する発毛抑制剤(特許文献2)が開示されているが、これらの植物抽出物の発毛抑制効果は十分満足できる効果まで至っておらず、更に効果の高いものが望まれている。

【発明の効果】
本発明の発毛抑制皮膚外用剤は、足や腕等の発毛を抑制し、毛再生の遅延効果を有する。[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hair growth-inhibiting skin external preparation, and more specifically, it contains a specific plant extract, suppresses hair growth on legs, arms, etc., and has a hair regeneration-inhibiting effect. It relates to an external preparation.
[0002]
[Prior art]
In general, when treating body hair, especially hair which is said to be waste, three methods of shaving, hair removal, and hair removal are performed. That is, shaving with a razor, hair removal by physical force such as a hair removal tape or wax, and a hair removal method by chemical treatment are used. In addition to the above-described method for hair removal, a high-frequency device may be used in an esthetic salon or the like. In addition, the treatment of wrinkles peculiar to men is mostly shaving with a razor or an electric razor. Then, after the treatment and shaving of these unwanted hairs, skin lotions and creams are applied for the purpose of moisturizing the skin and calming hot flashes, and the skin is optionally adjusted. Special cosmetics used after shaving are one of the most common cosmetics among male cosmetics.
[0003]
However, the waste hair treatment has the following disadvantages. That is, for shaving, a lot of minute scratches are generated on the skin, and for hair removal, treatment is technically painful, and it is very expensive when using a high-frequency device, and hair removal depends on chemical substances. It may be accompanied by skin irritation because hair is dissolved. As with the treatment of unwanted hair, shaving may result in minute scratches caused by razors and skin irritation such as razor loss. Furthermore, shaving and depilation only removes the hair on the surface of the skin, and even after depilation, the unwanted hair regenerates over time, so the above process is repeated. Especially for wrinkles, the growth rate is so fast that some people have to shave two to three times a day. In addition, since the treatment of waste hair has a strong stimulating effect on hair growth, there are problems of increasing the growth rate and activating resting hair. Accordingly, there has been a strong demand for a reduction in the processing frequency because of the heavy burden on the skin and the problems of the processing itself and costs.
[0004]
From such a background, for example, cosmetics that suppress hair growth by applying a plant extract such as Ichihatsu, Ononis, and soybean (Patent Document 1), and plants that contain a plant extract such as hydrangea and amateur. Although the hair inhibitor (patent document 2) is disclosed, the hair growth inhibitory effect of these plant extracts has not yet reached a sufficiently satisfactory effect, and a more effective one is desired.
[0005]

JP 2000-53538 A [0006]
[Problems to be solved by the invention]
Accordingly, an object of the present invention is to provide a hair growth-suppressing skin external preparation capable of effectively suppressing the growth of body hair and reducing the number of hair removal treatments.
[0007]
[Means for Solving the Problems]
In view of such circumstances, the present inventors have conducted various searches as a development theme to search for useful substances having an effect of suppressing hair growth, and as a result, by blending specific plant extracts, regeneration of waste hair and wrinkles is achieved.

[0022]
(1) Hair growth inhibitory effect test The back skin (2 cm × 4 cm) of C3H mice (7 weeks old, male, average weight 35 g) was cut with an electric clipper and a shaver, and Examples, Comparative Examples and Controls (Base Each sample of 50% ethanol aqueous solution was applied to the skin of the test area twice a day in the morning and evening, 0.2 mL per animal for 2 weeks. A group of 10 animals was used for one sample. On the 22nd day from the start of application, the skin of the test area of each sample was photographed with a video camera, and the areas of the hair cutting part and the hair growth part were measured with an image analyzer. According to the following formula (1), the hair growth rate (%) was calculated, and the average hair growth rate of each group of Examples, Comparative Examples and Controls was obtained. Next, the hair growth suppression rate (%) was calculated from the control hair growth rate according to the following formula (2).
Hair growth rate (%) = 100 × (area of hair growth part) / (area of hair cutting part) Formula (1)
Hair growth inhibition rate (%) = 100− (100 × (hair growth rate of examples or comparative examples) / (control hair growth rate)) (2)
[0023]
(2) Human practical test Ten healthy men and women were used as panelists, and the forearm portion of both arms was depigmented using a commercially available depilatory cream, washed and used as a test site. 5 mL of the sample of the example and the comparative example was uniformly applied to the test site on the right forearm after bathing once a day. The left forearm was used as a control without any application. 14 days after the start of application, the hair growth inhibitory effect was evaluated. In the evaluation method, the hair regeneration state of the right forearm to which the sample was applied was compared with the left forearm as a control with the naked eye and evaluated according to the following evaluation criteria.
