Description

【0001】
【発明の属する技術分野】
本発明は美白剤及び皮膚外用剤に関し、さらに詳細には、メラノサイトにおけるチロシナ−ゼの働きを阻害してメラニン産生を抑制し、紫外線照射後の皮膚に対する美白効果に優れ、また、日焼けなどによるシミ・ソバカス等を予防又は治療することが出来る美白剤及び皮膚外用剤に関する。
【0002】
【従来の技術、及び発明が解決しようとする課題】
シミ・ソバカスや日焼け後の皮膚色素沈着等は、皮膚内に存在する色素細胞の活性化によりメラニン産生が著しく亢進して生じるものであり、そのメカニズムについては必ずしも明確ではないが、チロシナ−ゼの働きによりチロシンからド−パ、ド−パからド−パキノンに変化したのち種々の中間体を経ることにより産生されるものと推測されている。このため、皮膚の黒色化を予防又は治療するためには、チロシナ−ゼの活性を阻害せしめ、また、メラニンを産生する過程の一部又は全部を阻害せしめる必要があるものである。
【0003】
ところで、従来より皮膚の黒色化を予防又は治療せしめるチロシナ−ゼ活性阻害剤やメラニン産生抑制剤としては、特開平6−256150号公報(特許文献1)、特開2002−128646号公報(特許文献2)等に開示されているように、アスコルビン酸、コウジ酸、アルブチン、あるいはハイドロキノン等が知られている。
しかしながら、上記アスコルビン酸は安定性に難があると共に、外用では効果が殆んど認められないものである。また、ハイドロキノンも物質自体の安定性(刺激性、アレルギ−性)に問題があるのみならず、白斑を生じさせるケ−スもある等の点から薬剤として配合することは問題があり、コウジ酸等についても安定性、安全性の面から必ずしも満足し得ないものである。

本発明は従来の問題点を解決し、優れた美白効果を有するのみならず、安定性・安全性に優れた美白剤及び皮膚外用剤を提供しようとするものである。
【0006】
【課題を解決するための手段】
本発明者は、皮膚の黒色化を予防・治療せしめるべく鋭意研究を行った結果、ピテセロビウムテニュクライブの抽出物が皮膚の黒色化を予防・治療する優れた効果を有するのみならず、安定性・安全性の面においても優れていることを知見し、本発明を完成するに至ったものである。
【0007】
即ち、本発明はピテセロビウムテニュクライブの抽出物を含有する美白剤及び皮膚外用剤を要旨とするものである。
【0008】
【発明の実施の形態】
本発明のピテセロビウムテニュクライブ(Pithecellobium tenue craib)は、マメ科(FABACEAE)に属する植物で、タイなど高温多湿で適度な降雨が認められる東南アジアで栽培されている。そして、かかるピテセロビウムテニュクライブの抽出物調製方法は特に限定されないが、生又は乾燥した樹皮を種々の溶媒を用い、低温から加温下において抽出する方法が挙げられる。具体的抽出媒体としては、水、メタノ−ル、エタノ−ル等の低級一価アルコ−ル、グリセリン、プロピレングリコ−ル、ジプロピレングリコ−ル、1,3−ブチレングリコ−ル等の液状多価アルコ−ル、酢酸エチル等の低級アルキルエステルを挙げることができ、これらの一種又は二種以上の混合溶媒を用いることが出来る。ピテセロビウムテニュクライブの抽出物は、そのまま用いてもよいが、必要に応じて濾過、濃縮してもよい。また、抽出物をカラムクロマト法、向流分配法等により、分画、精製して用いることも出来る。更に、上記の抽出物を減圧乾燥又は凍結乾燥した後、粉末又はペ−スト状に調製し、適宜製剤化して用いることも出来る。
【0009】
本発明の美白剤及び皮膚外用剤におけるピテセロビウムテニュクライブ抽出物の配合量は、特に限定はないが、効力、配合性、感触等の観点から乾燥固形物に換算して0.0001〜10.0重量%、好ましくは0.001〜5.0重量%,特に好ましくは0.01〜3.0重量%である。配合量が0.0001重量%未満では美白効果が乏しくなる傾向にあり、逆に10.0重量%を越えて配合しても効果の増加は実質上望めないし、皮膚外用剤への配合も難しくなる傾向にある。

Prior to measurement of tyrosinase activity, the medium in the wells was removed and washed twice with 100 μL of PBS. PBS containing 45 μL kl% Triin X (Rome and House trade name) was added to each well, the plate was shaken for 1 minute to disrupt the cell membrane, and the wavelength was 475 nm with a microplate reader. The absorbance was measured and this was taken as the absorbance at 0 minutes. Thereafter, 5 μL of a 10 mM L-DOPA solution was quickly added and incubated at 37 ° C. for 60 minutes. After shaking the plate for 1 minute, the absorbance was measured in the same manner as the absorbance at 60 minutes. The ratio of the difference in absorbance of the test sample with respect to the difference in absorbance at 0 minutes and 60 minutes when no test sample was added (control) was defined as the tyrosinase activity inhibition rate. The results are shown in Table 1.
