Description

本発明は、まつ毛を伸展させるための組成物に関する。   The present invention relates to a composition for extending eyelashes.

まつ毛は、埃などの異物が眼球に入るのを防止し眼球を守る機能を果たしているが、女性らしさや、目元をはっきりと美しく際立たせるチャームポイントとして強調する化粧の対象でもあり、長く、濃く、太くあることが望まれている。   Eyelashes prevent foreign objects such as dust from entering the eyeball and protect the eyeball, but they are also the target of makeup that emphasizes femininity and charm points that make the eyes clearly and beautifully long, dark, It is desired to be thick.

この目的において、従来よりまつ毛を伸ばす薬剤として、緑内障治療薬であるビマトプロスト(Bimatoprost、国内商品名:ルミガン、海外商品名:ラティース)が知られている。   For this purpose, bimatoprost (Bimatoprost, domestic product name: Lumigan, overseas product name: Lathis), a therapeutic agent for glaucoma, has been known as a drug for extending eyelashes.

ビマトプロストは、まつ毛のヘアサイクルに働きかけ、まつ毛の「成長期」を長くするため、まつ毛が「太く」「長く」「濃く」育つと考えられているが、眼瞼が黒くなる(色素沈着する)副作用、眼の中に入ると充血する/沁みるなどの副作用、さらにはまつ毛が異常に伸びる(多毛化)副作用などがある。このため米国ではまつ毛伸展剤として認可されているが、国内では認められていない。   Bimatoprost is considered to grow `` thick '', `` long '', and `` thick '' eyelashes in order to work on the eyelash hair cycle and lengthen the `` growth period '' of the eyelashes, but it has the side effect of making the eyelids black (pigmentation) There are side effects such as redness and itching when entering the eye, as well as side effects that cause eyelashes to grow abnormally (high hair). For this reason, it is approved as an eyelash extension agent in the United States, but it is not approved in Japan.

また本来は緑内障治療のための眼圧低下剤であり、健常者には視力低下等の副作用を引き起こすリスクも内在している。   It is originally an intraocular pressure reducing agent for the treatment of glaucoma, and has a risk of causing side effects such as decreased visual acuity in healthy individuals.

それ以外には、様々な民間療法が言われているが確たるものはない。
ビタミンD化合物が脱毛症に効果があるという報告があったが(特許文献1及び2を参照)、まつ毛の成長に効果があるという報告はなかった。
Other than that, a variety of folk remedies have been mentioned, but none are certain.
There were reports that vitamin D compounds were effective in alopecia (see Patent Documents 1 and 2), but there was no report that they were effective in eyelash growth.

従って、確実な効果と安全性を兼ね備えたまつ毛伸展剤は存在しないのが現状であり、そのような特長を備えた新たなまつ毛伸展剤が求められていた。   Accordingly, there is currently no eyelash extension agent that has both a certain effect and safety, and a new eyelash extension agent having such features has been demanded.
