Abstract
Description
(a)下記式(I)で表される疎水変性ポリエーテルウレタンを0.1~5質量%と、
(b)親水性板状粉末を0.01~5質量%と、
(c)疎水性粉末と、
(d)油分と、
(e)水と
を含むことを特徴とする:
R1-{(O-R2)k-OCONH-R3[-NHCOO-(R4-O)n-R5]h}m (I)
式(I)中、R1、R2およびR4は、それぞれ独立に炭素原子数2~4の炭化水素基を示し;R3はウレタン結合を有していてもよい炭素原子数1~10の炭化水素基を示し;R5は炭素原子数8~36の炭化水素基を示し;mは2以上の数であり;hは1以上の数であり;kは1~500の数であり;nは1~200の数である。水相(外層)中に含まれる劈開(へきかい)性のよい板状の親水性粉末が、疎水性粉末を含む油相(内層)を、疎水変性ポリエーテルウレタンを介して “つなぐ”ことにより、離水を防ぎ、弾力性を保持したまま固形状で安定に維持することができ、さらに手で取る際のわずかな応力で接合がはずれるため指どれが良く、また肌上での広がりがよくみずみずしい感触を実感させることができる。
本発明において(a)成分として用いられる疎水変性ポリエーテルウレタンは、下記式(I)で表される:
R1-{(O-R2)k-OCONH-R3[-NHCOO-(R4-O)n-R5]h}m (I)
このコポリマーは会合性増粘剤である。会合性増粘剤は、親水基部を骨格とし、末端に疎水性部分をもつコポリマーであり、水性媒体中でコポリマーの疎水性部分同士が会合し、親水部がループ状、ブリッジ状をなし、増粘作用を示す。
本発明において、親水性板状粉末(成分(b))は、外相(水相)に配合されて疎水性粉末を含む油相(内層)をつなぐ“つなぎ”として働く。劈開(へきかい)性のよい板状の親水性粉末で“つなぐ”ことにより、弾力性を保持したまま、容器成形可能な固形状で安定に維持することができ、さらに手で取る際のわずかな応力で接合がはずれるため指どれが良く、また肌上での広がりがよくみずみずしい感触を実感させることができる。本発明において使用される親水性板状粉は、化粧料に通常使用されている親水性の板状(薄片状)粉末であれば特に限られない。板状粉末とはアスペクト比(平均粒径/平均厚み)が1より大きい、例えば少なくとも5以上であることで球状粉末とは区別される。本発明における板状粉末は、板状(薄片状)であればアスペクト比は特に限定されないが、好ましくは、親水性板状粉末は10~100の平均アスペクト比を有し、より好ましくは20~100の平均アスペクト比を有し、さらに好ましくは40~100の平均アスペクト比を有する。平均アスペクト比が10未満では指どれがよくない傾向があり、また100を超えると安定な製剤が得られない場合がある。また、粒径は特に限定されないが、指どれしやすさの観点から、平均粒径が0.1~100μmである板状粉末が好ましく用いられる。
本発明において成分(c)として用いられる疎水性粉末は、粉末自体が疎水性のもののみならず、親水性粉末等であっても粉末表面を疎水化処理した疎水化処理粉末も含む。疎水性粉末は撥水性が強く、水や汗に強く、化粧くずれが最も起きにくいため効果の持続性に優れる。本発明は、肌に塗布する際の負荷により親水性板状粉末によるつなぎがはずれて外層(水相)が軟らかく広がってみずみずしさをもたらすとともに、内層(油相)の疎水性粉末が肌にうまく付着して化粧効果をもたらすことができる。
本発明の水中油型固形化粧料において用いられる成分(d)の油分は、疎水性粉末等を取り込んで内層(油層)を構成する。油分としては、通常化粧料に用いられる油分であれば特に限定されず、油脂、ロウ類、炭化水素油、高級脂肪酸、高級アルコール、合成エステル油、シリコーン等を用いることができるが、これら例示に限定されるものでない。
本発明の水中油型固形化粧料における水の含有量は、残余であり、本発明の固形製剤を形成できる限り限定されないが、通常20~80質量%であり、より好ましくは30~70質量%である。水の含有量がこの範囲であれば、より良好に固形状を保持することができ、みずみずしさや伸び広がりに優れた水中油型固形化粧料を作成することができる。
