Description
【0001】
【発明の属する技術分野】
本発明は皮膚外用剤に関する。
【0002】
【従来の技術および発明が解決しようとする課題】
糖セラミドは生体内に存在する脂質であり、これを配合した皮膚外用剤は塗布後、皮膚の水分含量を増加させ、荒れ肌改善効果に優れている。しかしながら、通常の糖セラミドは各種溶媒に対する溶解性が低いために油分や固形分が分離するなど安定性に欠け、系内で均一になりにくく、糖セラミドの製剤化は困難を極めていた。特にこの状況はローション剤型、ジェル剤型において顕著である。本発明は、このような実情に鑑みなされたものであって、これらの剤型において系としての均一性に優れ、保湿性に優れた皮膚外用剤を提供することを目的とするものである。
【0003】
【課題を解決するための手段】
本発明者は上記の目的を達成するために鋭意検討した結果、微生物由来の糖セラミドとヘキシレングリコールを含有する皮膚外用剤が、系としての均一性に優れることを見出した。即ち、本発明は、微生物由来の糖セラミドとヘキシレングリコールを含有することを特徴とする皮膚外用剤である。
【0004】
【発明の実施の形態】
以下、発明の実施の形態について詳述する。
【0005】
本発明の皮膚外用剤に用いられる微生物由来の糖セラミドは、例えばスフィンゴモナス属の微生物が産生するスフィンゴ糖脂質であり、その糖構造としてはグルコース、ガラクトースのような単糖類やガラクトシルマンノシルガラクトサミルアセチルグルコースのようなオリゴ糖を複数含む。尚、米糠由来の糖セラミドも知られているが、その糖構造はグルコースのみであり、水系での溶解性が低く、効果が発揮されがたく、ヘキシレングリコールを含有させても製剤化は困難である。本発明の微生物由来の糖セラミドとしては、例えば発酵セラミド(紀文フードケミファ社製)を挙げることが出来る。本発明の微生物由来の糖セラミドの配合量は、皮膚外用剤(組成物)の総量を基準として0.001〜5質量%(以下、%と略記する)が好ましい。この配合量の上限を越えても、その越えた配合量に見合った効果は期待できず、また下限未満の配合量では本発明の目的を達成することができないことがある。
【0006】
本発明の皮膚外用剤に用いられるヘキシレングリコールは公知の物質であり、その配合量は、皮膚外用剤(組成物)の総量を基準として0.02〜50%である。この配合量の上限を越えるとその越えた配合量に見合った効果は期待できず、また下限未満の配合量では本発明の目的を達成することができないことがある。
【0007】
本発明の皮膚外用剤は医薬品、医薬部外品、化粧品等に適用でき、剤形としては例えば、化粧水、乳液類、クリーム類、パック類、化粧油類、マッサージ類、化粧下地、ファンデーション、リップクリーム等に適用することができる。剤型としては、ローション剤型、ジェル剤型において好適である。
