Abstract
Description
(A)透明油性基剤と、(B)少なくとも1つの加飾層とを有する油性固形化粧料であって、
前記(A)透明油性基剤が(a1)増粘成分及び(a2)液状油分を含有し、
前記(B)加飾層が(b1)粉末成分を含有し、
前記(b1)粉末成分が、前記(a2)液状油分の屈折率より高い屈折率を有する粉末を少なくとも1種含むことを特徴とする、油性固形化粧料を提供する。
図1は、本発明の油性化粧料の一例を示す模式図である。図1(A)は上面図、(B)は断面図である。
図1に示す化粧料は、平皿容器1内に充填されており、透明油性基剤10と第1の加飾層11及び第2の加飾層12を有している。
図1の油性化粧料における前記第1及び第2の加飾層以外の部分は、透明油性基剤10から構成されている。
例えば、加飾層の数は同一面上又は複数の異なる面上に1つ又は複数設けてよく、それらの形状、色、大きさ及び厚みは同一でも異なっていてもよい。また、加飾層は、図1における第1の加飾層のように容器底面に設けても、透明基剤の表面に設けても、図1における第2の加飾層のように透明油性基剤の内部に設けてもよい。
本発明の油性化粧料を構成する透明油性基剤は、(a1)増粘成分と、(a2)液状油分とを含む。
本発明で用いるデキストリン脂肪酸エステルの分子量は、特に限定されないが、好ましくは1,000~300,000であり、さらに好ましくは1,000~100,000である。
本発明に用いられる液状油分は、前記増粘成分によって増粘(ゲル化)されて透明油性基剤を形成できるものであれば特に限定されず、化粧料に通常配合される常温(25℃)で液状の油分から選択することができる。代表例としては、炭化水素油、エステル油、シリコーン油、及び液体油脂から選択される液状油分が好ましく使用される。以下に具体例を例示するが、これらに限定されない。
なお、本発明における油の屈折率としては、例えば、ガラス板上に油を2gとり、金ベラを用いて均一なスラリー状になるまで練り合わせたものを、精密アッベ屈折計(ATAGO社製 タイプ:3T)を用いて20℃で測定した値を用いることができる。
固体油脂としては、例えば、カカオ脂、ヤシ油、馬油、硬化ヤシ油、パーム油、牛脂、羊脂、硬化牛脂、パーム核油、豚脂、牛骨脂、モクロウ核油、硬化油、牛脚脂、モクロウ、硬化ヒマシ油等が挙げられる。
本発明の油性化粧料における(B)加飾層は(b1)粉末成分を含有する。(b1)粉末成分は、上記(a2)液状油分の屈折率より高い屈折率を有する粉末を少なくとも1種含んでいる。
(1)前記(b1)粉末成分を(b2)分散媒体中に分散させたインク組成物を用いて描画することにより(B)加飾層を形成する工程、及び
(2)前記(A)透明油性基剤を容器内に充填する工程、を含む。
以下に、本発明の油性化粧料を、加飾層の形成にステンシルの技法を用いて製造する方法について、図1を参照して説明する。
なお、図1においては、前記の第1のインク組成物と第2のインク組成物は、互いに異なる色の粉末成分を含有している。
また、上記のステンシル技法を用いた製造方法は、スクリーン印刷装置又はインクジェット印刷装置等を用いて自動化した製造方法に変更することが可能である。
図2の写真には明瞭に現れていないが、この油性化粧料の全体は透明であり、内部に複数の色の層状(膜状)の加飾層を有する特異な外観を持ち、化粧料表面から光を照射すると加飾層の下に陰影が形成されて加飾層が立体的に浮き上がって見えるといった視覚効果がある。
しかし、表2の例Cに記載した組成のインク組成物を用いて容器底面に描画して加飾層を形成し、その上に表1の透明油性基剤を充填した場合(比較例1)では、加飾層が液状油分の屈折率より低い屈折率の粉末(シリカ)しか含んでいないため、加飾層の輪郭がぼやけて明瞭に視認できず、審美性に劣るものとなった(図3参照)。
