Description
本發明係關於一種可抑制皮脂為原因的角化不全之角化不全症抑制劑、可抑制因毛孔周圍皮脂中的刺激成分所引起的角化不全症、可防止.改善因不飽和脂肪酸所引起的皮膚粗糙之皮膚粗糙防止.改善劑、及具有角化不全症抑制、毛孔縮小、皮膚粗糙防止.改善的功能之皮膚外用組成物。
近年來,特別以年輕女性為主的毛孔顯著之煩惱更為嚴重,而需要改善此之皮膚外用組成物。然而,毛孔顯著的機制並未解明,以收斂化粧水或角栓的除去為一般對應方法。或以粉底企圖改善外觀。然而,例如收斂化粧水係以收斂皮膚為目的,藉由醇類暫時性地降低皮膚表面溫度、或藉由有機酸等、或凝固蛋白質之作用而達成。因此其為暫時性地收斂者,對於皮膚的負擔過大,且無法具體的解決毛孔之顯著,其效果亦未充分。
另一方面,亦有報告指出甘胺酸或抗壞血酸衍生物具有毛孔縮小效果(例如,參照非專利文獻1),其作用機制或效果程度等亦不明。
又,角栓除去係為將塞住的角栓以物理性方法除去,例如已知有藉由含具有鹽生成基之高分子化合物的角栓除去劑(例如,參照專利文獻1)、含有水不溶性環糊精聚合物之化粧品(例如,參照專利文獻2)、含有50質量%以上的黏度為5~80mPa.s/25℃之油份的角栓除去用化粧料(例如,參照專利文獻3)等除去。使用如此角栓之除去方法,有時其物理性力量會傷害皮膚,而使該皮膚之副作用成為問題。又該效果僅為暫時性,角栓馬上會再生、或角栓除去後相反地毛孔會變大,故其效果並不充分。
本發明者對於改善毛孔顯著之皮膚外用組成物的開發、毛孔顯著之機制做詳細檢討結果,發現(1)毛孔部周圍陷入如研缽狀之部份定義為毛孔,當該部份擴充時則會顯著、(2)該研缽狀部份的角層成角化不全狀態(殘存著本應消失的核)、(3)毛孔顯著的人之皮脂量、特別為不飽和脂肪酸較多。
(4)該不飽和脂肪酸成為角化不全的原因。
(5)毛孔的顯著以皮脂中的不飽和脂肪酸為原因之可能性為高。此發表於第102回日本皮膚科學會總會(參照非專利文獻2)。
由上得知,關於毛孔顯著之機制,皮脂為原因所引起的角化不全為其中一因素。且,得知藉由改善角化不全可改善毛孔之顯著。
更進一步地,探索具上述角化不全抑制效果與毛孔縮小效果之藥劑的結果發現,興奮性細胞受體的對抗物或抑制性細胞受體的致效劑皆具這些機能(參照專利文獻4),做為這些代表例而可舉出者,例如作為前者對抗物之D-谷胺酸或TNP-ATP,以及作為後者致效劑之白楊黃素、β
-丙胺酸、GABA、絲胺酸、牛磺酸等。
然而,以往的化合物,其角化不全抑制效果、毛孔縮小效果、皮膚粗糙防止.改善效果等之效果並未充分,又具有感覺刺激,在皮膚外用組成物的應用上其摻合受到限制,換言之,就作為角化不全抑制劑、毛孔縮小劑、皮膚粗糙防止.改善劑而言,其效果並未充分,故更優秀化合物的開發被期待。

本發明為鑑於上述事項所成者,其目的為提供一種具有角化不全抑制、毛孔縮小、皮膚粗糙的防止.改善等功能,且無感覺刺激等之安全性上的問題,亦即高安全性之角化不全症抑制劑、毛孔縮小劑、皮膚粗糙的防止.改善劑,更者提供一種摻合具有前述功能的化合物之皮膚外用組成物。
本發明者欲解決上述課題,基於上述之見解進行具有因不飽和脂肪酸之角化不全抑制作用之化合物的研究探討,其結果發現特定α-胺基酸衍生物及其鹽具有前述作用,無感覺刺激且安全性高,可解決上述課題,進而完成本發明。

欲對於藉由油酸塗佈之皮膚粗糙之α-胺基酸衍生物及其鹽之抑制效果進行調查,測定塗佈前與塗佈後的水分蒸散量(TEWL值),其差與對照值(對照水溶液)比較,調查其效果。試料的調製及塗佈方法依據實施例1。且TEWL使用TEWA meter TM210(Courage+Khazaka公司)進行測定。
於無毛鼠(HR-1;各群4匹)的背部塗上100μl的10質量%的油酸(溶劑:乙醇)。其後塗上100μl的試料溶液(α-胺基酸衍生物等)。繼續3天後的第一天測定背部的TEWL值,求得4匹的平均值。結果如表3所示。△TEWL值越大表示皮膚粗糙越惡劣。
如表3得知,藉由塗佈N-甲基-L-絲胺酸、N-甲基-DL-絲胺酸、N-甲基-D-絲胺酸、N-乙基-L-絲胺酸、N-乙基-DL-絲胺酸、N-乙基-D-絲胺酸、N-甲基-L-丙胺酸、N-甲基-DL-丙胺酸、N-甲基-D-丙胺酸、N-乙基-L-丙胺酸、N-乙基-DL-丙胺酸、N-乙基-D-丙胺酸、N-苄酯基-L-絲胺酸、N-苄酯基-DL-絲胺酸、N-苄酯基-D-絲胺酸、N-苄酯基-L-丙胺酸、N-苄酯基-DL-丙胺酸、N-苄酯基-D-丙胺酸、N-環己基甘胺酸、N-環己基-DL-絲胺酸、N-環己基-L-絲胺酸、N-環己基-D-絲胺酸、N-環己基-L-丙胺酸、N-環己基-DL-丙胺酸、N-環己基-D-丙胺酸、N-苯磺醯基甘胺酸、N-苯磺醯基-L-絲胺酸、N-苯磺醯基-DL-絲胺酸、N-苯磺醯基-D-絲胺酸、N-苯磺醯基-L-丙胺酸、N-苯磺醯基-DL-丙胺酸及N-苯磺醯基-L-丙胺酸後,△TEWL值與對照水溶液相比顯著低,確認有皮膚粗糙防止、改善效果。另一方面,同樣地非α-胺基酸之本發明範圍的衍生物之N-乙醯基甘胺酸、馬尿酸及膦甲基甘胺酸不具效果。
使用棉棒將實施例1中所調製之對照水溶液與試料水溶液各1ml各自塗抹於20位女性受驗者之左右任一臉頰部,從塗抹一開始後至10分鐘內,每30秒評價1次刺激感,然後報告最終的評價。刺激感的評價基於以下4階段的基準評價點來進行評價,算出評價點的平均後,將其分類成以下的基準。
(基準評價點)3:撕裂感、發熱感、刺痛感、發癢感等之刺激非常強烈,不可繼續塗抹2:撕裂感、發熱感、刺痛感、發癢感等之刺激強烈,不能忍受1:雖稍微感覺到撕裂感、發熱感、刺痛感、發癢感等之刺激,但可忍受0:沒有特別地感覺到刺激
(評價基準)A:評價點平均未達0.2 B:評價點平均0.2~1.0以下C:評價點平均1.0~2.0以下D:評價點平均2.0以上結果顯示於表4。
