Abstract

Description

本発明は、皮膚化粧料組成物に関するものである。 The present invention relates to a skin cosmetic composition.

化粧水のような大部分を水で構成された水性化粧料は、肌の環境を整えるために用いられる基礎化粧品であり、保湿や肌のpHを調整することを目的として使用される。 Aqueous cosmetics, which are mostly composed of water such as lotion, are basic cosmetics used for adjusting the environment of the skin, and are used for the purpose of moisturizing and adjusting the pH of the skin.

水性化粧料は大部分が水であるため、油性成分が配合された化粧料に比べさっぱりとした感触が得られるものの、肌は親油性であるため、比較的肌になじみにくいといった問題があった。 Since most of the water-based cosmetics are water, a refreshing feel can be obtained compared to cosmetics containing oily ingredients, but since the skin is lipophilic, there is a problem that it is relatively difficult to fit into the skin. ..

前記の課題に対応する先行技術文献として、ポリエーテル変性シリコーンと酸性ムコ多糖類を含有した水性皮膚化粧料が提案されている(特許文献1参照)。しかし、この提案は、安全性の面で忌避されることのあるポリエーテル変性シリコーンを用いている。 As a prior art document corresponding to the above problem, an aqueous skin cosmetic containing a polyether-modified silicone and an acidic mucopolysaccharide has been proposed (see Patent Document 1). However, this proposal uses polyether-modified silicone, which can be repelled in terms of safety.

また、ジプロピレングリコール、ポリオキシアルキレンアルキルグルコシドなどを含有する皮膚外用剤が提案されている(特許文献2参照)。この提案では、次に使用する化粧水等の機能性化粧料の肌馴染み改善効果を謳うものの、化粧水自体への配合ではないため、2度にわたる化粧料の塗布が必要となる。 Further, a skin external preparation containing dipropylene glycol, polyoxyalkylene alkyl glucoside and the like has been proposed (see Patent Document 2). In this proposal, although the effect of improving the skin familiarity of the functional cosmetics such as the toner to be used next is touted, the cosmetics need to be applied twice because it is not added to the toner itself.

したがって、安全性の高い原料を用い、皮膚化粧料自体の肌馴染みが良い組成物の開発が求められている。 Therefore, it is required to develop a composition which uses highly safe raw materials and has a good skin compatibility with the skin cosmetic itself.
