Abstract

This study was to verify the skin safety of Coptis Japonica extract(CJE) -containing cosmetics by patching them on sensitive skin and checking its stimulating level. 32 subjects diagnosed with sensitive skin by the result of the lactic acid injury test, were subjected to 20 ㎕ of solubilized essence mixed with 2% CJE on the test subjects' back and closed patched for 24 hours. No stimulus reactions were found by bare eyes and scored 0 stimulus figure points after they were taken off in 30 minutes, 24 hours, and 48 hours. Coptis japonica's medical efficacies such as antioxidant, and anti-inflammatory are expectable to be used as functional cosmetics, and this research would be the foundation of further research into its cosmetical usage.

황련(Coptis Japonica)의 뿌리로 제조한 황련 추출물 화장품이 민감한 피부에도 안전한지 검증하기 위해 민감성 피부를 대상으로 인체 첩포 시험을 실시하였다. 젖산 자상 검사 결과 민감성 피부로 판정한 총 32명의 시험대상자에게 황련 추출물을 2% 배합한 가용화 에센스를 시험대상자 등 부위에 20 ㎕ 취하여 24 h 동안 폐쇄 첩포한 후 이를 제거하고 30 min과 24 h 후의 시험 부위를 피부과 전문의가 육안으로 관찰하여 피부 자극 지수를 산출하였다. 그 결과 육안으로 이상 반응이 확인되지 않았고 자극 지수가 총 0점으로 나타나 황련 추출물 2%를 배합한 화장품이 민감한 피부에 안전한 것을 확인하였다. 다수의 황련 연구에서 항균, 항산화, 항염 등의 활성이 밝혀지고 화장품 소재로 이용 가능성이 보고되고 있지만 본 연구를 통해 황련 추출물 화장품이 민감한 피부에도 안전한 것으로 나타나 향후 황련 화장품의 무자극 또는 저자극의 소재연구에서 본 연구가 기초 자료로 활용될 것으로 기대된다.
