Abstract
Description
なお、本明細書で用いる「固形」という語は、化粧料の分野で通常用いられている意味に解され、例えば、50℃以下の温度において組成物全体が流動性を示さず、通常の保管条件下において著しい変形を示さない形態または状態と定義することができる。
以下に本発明の油中水型乳化固形化粧料を構成する各成分について詳述する。
本発明における「内相粉末」とは、化粧品、医薬品に通常使用可能な粉体であって、水系に安定して分散し得る表面親水性の粉末を意味する。表面親水性の粉末は、表面疎水化処理をしていない親水性粉末、及び親水性物質で表面処理した疎水性又は親水性の粉末を包含する。
本発明の化粧料では、顔料級酸化チタン及び微粒子酸化チタンの両方またはいずれか一方を含むのが好ましい。特に、少なくとも親水性微粒子酸化チタンを配合するのが好ましい。
水溶性増粘剤としては、キサンタンガム、セルロースガム、アラビアガム、カラギーナン、ペクチン、カンテン、クインスシード(マルメロ)エキス、デンプン、アルゲコロイド(褐藻エキス)、ムコ多糖類、シロキクラゲ多糖類、サクシノグリカン等の植物系高分子、デキストラン、プルラン等の微生物系高分子、コラーゲン、カゼイン、ゼラチン等の動物系高分子、カルボキシメチルデンプン、メチルヒドロキシプロピルデンプン等のデンプン系高分子、アルギン酸ナトリウム等のアルギン酸系高分子、カルボキシビニルポリマー(カルボマー)等のビニル系高分子、ポリオキシエチレン系高分子、ポリオキシエチレンポリオキシプロピレン共重合体系高分子、ポリアクリル酸ナトリウム、ポリアクリルアミド等のアクリル系高分子、ベントナイト、ケイ酸アルミニウムマグネシウム、ラポナイト等の無機系水溶性高分子等が挙げられる。
水溶性薬剤としては、ビタミンA、レチノール、パルミチン酸レチノール、イノシット、塩酸ピリドキシン、ニコチン酸ベンジル、ニコチン酸アミド、ニコチン酸DL-α-トコフェロール、アスコルビン酸リン酸マグネシウム、アスコルビン酸2-グルコシド、ビタミンD2(エルゴカシフェロール)、dl-α-トコフェロール2-Lアスコルビン酸リン酸ジエステルカリウム塩、dl-α-トコフェロール、酢酸dl-α-トコフェロール、パントテン酸、ビオチン等のビタミン類、アラントイン、アズレン、グリチルレチン酸等の抗炎症剤、アルブチン、トラネキサム酸、4-メトキシサリチル酸カリウム等の美白剤、酸化亜鉛、タンニン酸等の収斂剤、イオウ、塩化リゾチーム、塩酸ピリドキシン、γ-オリザノール等が挙げられる。
本発明で使用されるワックスは、メーキャップ化粧料に従来から用いられているワックスから選択することができる。
具体例としては、カカオ脂、ヤシ油、馬油、硬化ヤシ油、パーム油、牛脂、羊脂、硬化ヒマシ油、水添野菜油等の固体油脂、パラフィンワックス(直鎖炭化水素)、マイクロクリスタリンワックス(分岐鎖飽和炭化水素)、セレシンワックス、モクロウ、フィッシャートロプスワックス等の炭化水素類、ミツロウ、ラノリン、カルナウバロウ、キャンデリラロウ、コメヌカロウ(ライスワックス)、ゲイロウ、ホホバ油、ヌカロウ、モンタンロウ、カポックロウ、ベイベリーロウ、セラックロウ、サトウキビロウ、ラノリン脂肪酸イソプロピル、ラウリン酸ヘキシル、還元ラノリン、硬質ラノリン、POEラノリンアルコールエーテル、POEラノリンアルコールアセテート、POEコレステロールエーテル、ラノリン脂肪酸ポリエチレングリコール、POE水素添加ラノリンアルコールエーテル等のロウ類、ミリスチン酸、パルミチン酸、ステアリン酸、ベへニン酸、ヒドロキシステアリン酸等の高級脂肪酸、セチルアルコール、ステアリルアルコール、ベヘニルアルコール、ミリスチルアルコール、セトステアリルアルコール等の高級アルコールなどが挙げられ、これらの1種または2種以上を組み合わせて使用することができる。これらの中でも、パラフィンワックス(直鎖炭化水素)、コメヌカロウ(ライスワックス)、ヒドロキシステアリン酸、硬化ヒマシ油、水添野菜油等を用いるのが好ましい。
ワックス及びゲル化剤の合計配合量は、化粧料全量に対して0.1~15質量%となるようにすることが好ましく、より好ましくは0.5~10質量%、さらに好ましくは1~7質量%である。ワックス及びゲル化剤の合計配合量が0.1質量%に満たないと油相が十分に固化しないことがあり、15質量%を超えると化粧料が固くなりすぎて使用感が低下することがある。
本明細書における外相粉末とは、上記内相粉末として例示した親水性粉末にシリコーンやフッ素、テフロン(登録商標)、脂肪酸、脂肪酸石鹸、ラウロイルリジン等により表面疎水化処理を施した粉末、シリコーン樹脂粉末等の元来表面が疎水性の粉末を意味し、従来の油中水型乳化固形化粧料において外油相に配合されていた粉末成分が該当する。特に、化粧料の使用性を良好にする球状粉末を外相粉末として配合するのが好ましい。
(1)水性媒体、カチオン性及び/または両性の粉末分散剤、水溶性増粘剤及び他の任意成分を、必要に応じて加熱しながら混合した後、内相粉末を添加してホモミキサー等で撹拌混合し、水相成分を調製する。
(2)ワックス及び/またはゲル化剤、液状油分、及び他の任意成分を、必要に応じて加熱しながら混合して、油相成分を調製する。
(3)油相成分に任意に乳化剤を添加し、水相成分を添加してホモミキサー等を用いて攪拌混合し乳化物とする。
