Description
本発明は、スキンケア組成物に関する。特に、本発明は、組成物の0.0001~10重量%のリン脂質、多孔質粒子およびシリコーンエラストマーを含むスキンケア組成物に関し、ここで、多孔質粒子対シリコーンエラストマーの重量比は、1:30~30:1である。
老化により、皮膚の外観には多くの変化が生じる。若々しい外観を維持したいと望む個人にとっての関心事は特に、シワ、加齢斑、または皮膚の色調の全般的な不均等といった皮膚の不完全さの減少または排除である。
第1の局面において、本発明は、組成物の0.0001~10重量%のリン脂質、多孔質粒子およびシリコーンエラストマーを含むスキンケア組成物を対象とし、ここで、当該多孔質粒子対当該シリコーンエラストマーの重量比は、1:30~30:1である。
実施例中、または別途明示的に示されている場合を除き、本記述中の、反応の材料または条件の量、材料および/または使用の物理的特性を示す全ての数は、任意に「約」の語によって修飾されたものとして理解され得る。
材料
この例によって、本発明のスキンケア組成物の即時ぼかし効果が改善したことが実証された。
ポリウレタンエラストマーで作られたシワ付きバイオスキンプレート(BP-EW1 #BSC、ビーラックス株式会社、東京、日本)を基材として、シワのあるヒト皮膚を模倣した。SAMBA (Bossa Nova Technologies、米国)と呼ばれる二重偏光画像システムを用いて、松原明[皮膚透光性:何がどのように測定されているか、どのように測定されているか、国際化粧品連合(IFSCC)会議2006、大阪、日本]が記載した方法と原理に従ってシワのあるバイオスキンプレートの光沢度を測定した。解析にはSAMBA face system(Version 4.3)と名付けたソフトウェアを装備した。Wrinkled Bio―skinプレートを80msecの曝露時間で入射光に対して試験した。動作モードは平行偏波および交差偏波モードであった。
入射光を、Bio‐skinプレートによって反射および散乱した。鏡面反射光は入射光と同じ偏光を保ち、一方、体積(拡散光)からの散乱光は非偏光であった。SAMBAカメラは偏光の二つの状態(平行と交差)に対応する二つの画像を逐次取得した。平行画像強度(P)には反射光と散乱光の両方が寄与し、交差画像強度(C)は散乱光のみが寄与する。平行画像に交差画像を加えたものは、従来のカメラで配信された画像、または人間の目で知覚された画像の合計に等しい。
