Abstract
Description
一般にこれらの微細エマルションは、高圧乳化機などの高シェア力をかけることができる乳化機を用い、高い剪断力でエマルションの乳化粒子を微細化して製造する。
しかしながら、高圧乳化機による微細エマルション調製は製造コストの上昇にもつながり、また高い剪断力での処理は各種機能性原料の変性の原因ともなり得る。
尚、微細エマルションのうち、熱力学的に平衡なものをマイクロエマルションと言う。
すなわち、本発明にかかる化粧料は、
平均乳化粒子径が150nm以下である微細エマルション型化粧料であって、
連続層である水相と、
前記水相中に分散され、油相中82質量%以上のシリコーンオイル及び炭化水素油を含む油相と、
下記一般式(1)で表されるカルボキシ変性シリコーンと、
C16~22の高級アルコールと、
POE鎖を有する、HLBが5~10の非イオン性界面活性剤と、
2価グリコールと、
を含むことを特徴とする。
また、油相中のシリコーン:炭化水素油の質量比が、1:9~9:1であることが好適である。
また、本発明にかかる化粧料において、
(油剤)/(カルボキシ変性シリコーン+高級アルコール+非イオン性界面活性剤)
の質量比が1.5以下であることが好適である。
また、本発明にかかる微細エマルション型化粧料の製造方法は、前記式(1)であらわされるカルボキシ変性シリコーンの酸部、高級アルコール、非イオン界面活性剤、油相、有機アミン及び/またはアルカリ金属、水相の一部、二価グリコールを混合することでマイクロエマルションを調製し、
さらに水相の残部を添加希釈する。
上記一般式(1)において、R1~R3は、少なくとも1つが-O-Si(R4)3で表される官能基(R4は、炭素数1~6のアルキル基又はフェニル基のいずれかである)である。なお、R1~R3において、その全てが前記官能基のいずれかであってもよい。あるいは、R1~R3の少なくとも1つが前記官能基であれば、その他のR1~R3は、同一または異なっていてもよい置換又は非置換の一価炭化水素基のいずれかであってもよい。
R1R2R3Si-(CH2)2-COOM (1’)
また、本発明に用いられる炭素数16~22の一価脂肪族アルコール(以下、単に高級アルコールという)は、飽和又は不飽和の1価脂肪族アルコールであって、直鎖状、分岐状のいずれであっても構わないが、直鎖状であることがより好ましい。また、融点40℃以上の高級アルコールであることが好ましい。本発明に用いられる炭素数16~22の高級アルコールとしては、例えば、ステアリルアルコール、イソステアリルアルコール、オレイルアルコール、オクチルドデカノール、キミルアルコール、セタノール、セトステアリルアルコール、ヘキシルデカノール、ベヘニルアルコール、等を挙げることができる。なお、本発明においては、単独で融点40~80℃の高級アルコールを用いるか、あるいは融点が40~70℃となるように複数の高級アルコールの組み合わせを用いることが好ましい。
高級アルコールの添加量は、微細エマルションを調製する段階で、組成物中2~10質量%存在することが好ましく、3~8質量%であることがより好ましい。
本発明に用いられる非イオン性界面活性剤としては、HLB5~10、好ましくはHLB6~9であって、POE基を有するものが好ましい。
具体的には、ステアリン酸PEG-5グリセリル、POE(6)ステアリルエーテル、POE(10)硬化ひまし油、POE(20)硬化ひまし油などが例示される。
非イオン界面活性剤の添加量は、微細エマルションを調製する段階で、組成物中2~15質量%存在することが好ましく、5~10質量%であることがより好ましい。
本発明に用いられる二価グリコールとしては、ジプロピレングリコール、エチレングリコール、ジエチレングリコール、プロピレングリコール、1,3-ブチレングリコールなどが例示され、微細エマルションを調製する段階で、組成物中10~30質量%存在することが好ましく、15~25質量%であることがより好ましい。
本発明の油相として用いられる油剤は、シリコーン油および炭化水素油を含むものである。

本発明において、油相としては前記シリコーン油と炭化水素油が82質量%以上を占めることが必要である。シリコーン油ないし炭化水素油以外のエステル油などが油相中に18質量%以上含まれると、微細エマルションの調整が困難となる。
また、油相の配合量は、微細エマルションを調製する段階で、
油剤/(カルボキシ変性シリコーン+高級アルコール+非イオン性界面活性剤)=1.5以下となる量であることが好ましい。
1.5を超えると微細エマルションの調製が困難となる場合がある。油剤配合量の下限は特にないが、微細エマルションの性質上、微細エマルションを調製する段階で組成物中10質量%以上であることが好ましい。
以下、本発明の実施形態について詳細に説明する。
まず、本発明者らは、各種組成を用いて微細エマルションの調製を試みた。
結果を表1に示す。
すなわち、界面活性剤(酸部)、高級アルコール、非イオン界面活性剤及び二価グリコールとともに油剤を80℃にて溶解・混合した。
そして、前記界面活性剤の対イオンとしてのトリエタノールアミンを当量溶解した水相(室温)を添加・混合・冷却し、55~65℃で相状態の確認を行った。
この結果、カルボキシ変性シリコーンを用いた試験例1-1(本発明)はほぼ透明な一相系となる。前記水を加えた系ではシリコーン油(ポリジメチルシロキサン 6CS)、炭化水素油(オレフィンオリゴマー)の溶解は困難であるが、透明一相系となることでマイクロエマルションが形成されていることが確認できる。
これに対し、試験例1-2ないし1-3では、脂肪酸(ステアリン酸、オレイン酸)を用いてエマルションの調製を試みたが、白濁2相系となった。
一方、試験例1-4では、高圧乳化を用いて試験例1-2(界面活性剤としてステアリン酸を用いた系)の微細なエマルションの調製を試みたところ、調製可能であった。
以上のようにカルボキシ変性シリコーンを用いた系では、特定の高級アルコール、非イオン界面活性剤、及び二価グリコールを用いることで、通常の混合装置を用いマイクロエマルションの調製が可能であることが理解される。
さらに本発明者らは、油剤配合量と他成分の関係を調査した。結果を表2に示す。
油剤配合量/(カルボキシ変性シリコーン+高級アルコール+非イオン界面活性剤)
が、1.5以下であると良好なマイクロエマルションの調製が可能であることが理解される。
次に本発明者らは、油剤の種類とマイクロエマルション調製の関係について検討を行った。結果を表3に示す。
なお、シリコーン油および炭化水素油は両者が必要であり、各単独の場合(試験例3-5,3-6)には良好なマイクロエマルションの調製が困難であった。
次に本発明者らは、高級アルコールに関し検討を行った。結果を表4に示す。
表4より明らかなように、ベヘニルアルコールと脱臭セタノールはほぼ同様な挙動を示し、高級アルコールの配合量に関しては、前記油剤配合量との関係が崩れない限り、可変であることが理解される。なお、最終的な化粧水状組成物中の油滴粒径を測定したところ、平均粒径が100nm前後であり、微細なエマルションであることが確認された。
次に本発明者らは、各種非イオン界面活性剤を用いて化粧水状組成物を調製し、その評価を行った。結果を表5に示す。
次に本発明者らは、二価グリコールに関し検討を行った。結果を表6に示す。
しかしながら、第二水相ないし第三水相はマイクロエマルションを希釈分散させるためのものであるため第二水相ないし第三水相に二価グリコールなどを添加することは、マイクロエマルションの状態に悪影響を及ぼすものではない。
次に本発明者らは、カルボキシ変性シリコーンの対イオン及び中和度について検討を行った。結果を表7及び8に示す。
