【発明の属する技術分野】
本発明は足や腕等の発毛を抑制する発毛抑制剤に関する。
【0002】
【従来の技術及び発明が解決しようとする課題】
哺乳類の頭髪や体毛は、生物学的には頭部、胸部、手足等の重要な器官を防護するものであるが、近年、特に手足等における体毛は美的外観上はない方が好ましいとする傾向が高まり、このため各種の体毛除去方法、例えばシェーバー、抜毛器等を用いる機械的除去方法、脱毛剤を用いて体毛を毛根から抜去する方法、除毛剤を用いてその化学的作用により体毛を除去する方法等が利用されている。
【0003】
しかしながら、これらの体毛除去方法は、皮膚に対して物理的又は化学的刺激を伴うものであり、また、体毛除去方法によって多少の差はあるものの体毛除去効果の持続性には限度がある。このため、一定期間経過後には再び体毛除去処理を行わなければならず、体毛除去処理の軽減化が望まれている。
【0004】
本発明の目的は、体毛の発育を効果的に抑制して体毛除去処理回数を減少させることのできる発毛抑制剤を提供することにある。
【0005】
【課題を解決するための手段】
本発明者らは、安全性の高い天然物質を種々探索したところ、特定の植物に優れた体毛成長抑制作用があることを見出した。
【0006】
すなわち本発明は、サイコ、ソヨウ、ダイオウ及びモクツウから選ばれる生薬又はその抽出物からなる発毛抑制剤を提供するものである。
【0007】
【発明の実施の形態】

【Example】
Production Example 1 Preparation of herbal extracts 100 mL of various extracts shown in Table 1 were prepared according to a conventional method.
[0018]
[Table 1]
[0019]
Example 1 Hair Growth Inhibition Test Using Mice The back hair of a group of 5 C3H mice aged 6 weeks old was shaved over 2 × 4 cm 2 using an electric clipper and an electric shaver so as not to damage the skin. Samples were applied to the shaved site twice a day at 100 μL for 3 weeks from 1 week before shaving. The test substance was dissolved in a solvent (50% ethanol) and adjusted to the concentrations shown in Table 2. Only the solvent was applied to the symmetry group. Two weeks later, in order to observe the regenerated hair, the shaved portion was photographed at a constant magnification, and the regenerated hair area ratio (regenerated hair area / shaved area) was compared with the target group using an image analyzer. The hair growth inhibition rate was expressed as a relative value (%) when the regenerated hair area ratio of the subject group was 100. The results are shown in Table 2.
[0020]
[Table 2]
[0021]
From Table 2, it was shown that the crude drug of the present invention has an excellent hair growth inhibitory effect.
[0022]
【The invention's effect】
If the hair growth inhibitor of this invention is used, the growth of body hair can be suppressed effectively and the frequency | count of a body hair removal process can be reduced. In addition, the hair becomes thinner, and it is particularly easy to remove the hair from the legs and arms.
