【発明の属する技術分野】
本発明は、優れた保湿効果を有し、肌荒れの防止や改善に優れた効果を発揮する皮膚外用剤に関し、さらに詳しくは、優れた保湿効果を有するヒルギ科(Rhizophoraceae)植物抽出物を含有し、肌荒れの防止や改善に優れた効果を発揮する皮膚外用剤に関する。
【0002】
【従来の技術】
加齢や疾患による皮膚のバリア機能,水分保持機能の低下や冷暖房等の外的環境による低湿度状態から生じる皮膚の乾燥は、肌荒れを引き起こす重要な要因となっている。皮膚の乾燥によって生じた肌荒れは、小ジワや皮膚の透明感の低下といった皮膚症状を引き起こすだけでなく、痒みや湿疹といった皮膚疾患の原因ともなっている。このため、皮膚の乾燥を防ぎ、肌荒れを防止あるいは改善する保湿剤は、非常に有用性が高いと考えられ、これまで皮膚外用剤の分野では、様々な保湿剤の検索や配合検討がなされてきた。従来の保湿剤としては、グリセリン,1,3−ブチレングリコール,ソルビトール等の多価アルコール、アミノ酸,ピロリドンカルボン酸等の天然保湿因子、コラーゲン,ヒアルロン酸等の生体内高分子、及び薬用植物をはじめとする多種類の植物抽出物などが挙げられる。
【0003】
しかし、すでに報告されている保湿剤のいずれにおいてもその保湿効果や肌荒れの改善効果は必ずしも十分であるとはいえず、皮膚外用剤の基剤中に配合した場合、有効な効果を得るにはかなりの高濃度を配合しなければならず、製剤に好ましくない色や臭いを付与してしまう場合があるなど、作用効果や安定性の面ですべてを満足できるものが少ないのが現状であった。
【0004】
【発明が解決しようとする課題】
そこで、本発明においては、保湿効果に優れ、肌荒れの防止や改善に優れた効果を発揮する皮膚外用剤を提供することを目的とした。
【0005】
