Description
【0001】
【発明の属する技術分野】
本発明は、テンジクアオイ属に属するペラルゴニウム シトロスム(Pelargonium citrosum)抽出物を配合することを特徴とする皮膚外用剤に関し、更に詳細にはPelargonium citrosum抽出物とジオール化合物を含有することにより、安全性が高く美肌効果に優れた皮膚外用剤に関する。
【0002】
【従来の技術】
化粧料等の皮膚外用剤において、美しい肌を形成することは健康上も美的にも大きな目的である。従来種々の植物抽出物や化合物等について検討されているが未だ完全なるものは得られていないのが現状である。
【0003】
Pelargonium citrosumは中国産シトロネラとアフリカ産ゼラニウムを細胞融合し、育成されたテンジクアオイ属に属する新種の植物である。その外観はゼラニウム(Pelargonium graveolens)に似ている。このPelargonium citrosumは欧米ではMosquito Fighter、日本では蚊連草として発売されており、その名の通り蚊がよって来ないことが知られている。
【0004】
このPelargonium citrosumに含まれる香気成分については既に報告がなされており、その主成分としてゲラニオールやリナロール、イソメントンなどのテルペン化合物が確認されている(非特許文献1参照)。この抽出物の応用としては抽出物を吸着することにより防蚊効果を訴求した繊維構造体が提案されている(特許文献1参照)。しかしながら、このPelargonium citrosum抽出物の皮膚外用剤における応用に関する検討は全くなされていなかった。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an external preparation for skin characterized by blending an extract of Pelargonium citrosum belonging to the genus Tenjikuoi, and more particularly to containing Pelargonium citrosum extract and a diol compound. The present invention relates to a skin external preparation that is high and has an excellent skin effect.
[0002]
[Prior art]
Forming beautiful skin in skin external preparations such as cosmetics is a major purpose both in health and aesthetics. Conventionally, various plant extracts, compounds, and the like have been studied, but at present, no complete product has been obtained.
[0003]
Pelargonium citrosum is a new species of plant belonging to the genus Periphyton, which has been bred by cell fusion of Chinese citronella and African geranium. Its appearance resembles geranium (Pelargonium gravelens). This Pelargonium citrosum is marketed as Mosquito FIGter in Europe and the United States and as a mosquito reed in Japan, and as its name implies, it is known that mosquitoes do not come.
[0004]
Aroma components contained in this Pelargonium citrosum have already been reported, and terpene compounds such as geraniol, linalool, and isomentone have been confirmed as main components thereof (see Non-Patent Document 1). As an application of this extract, there has been proposed a fibrous structure which advertises the mosquito-proof effect by adsorbing the extract (see Patent Document 1). However, no study has been made on the application of this Pelargonium citrosum extract to an external preparation for skin.
