한련초 추출물을 이용한 모발염색의 매염방법에 관한 연구

A Research about the hair dye using the extract of Hanryencho depending on the mordanting methods

&nbsp;&nbsp;In order to development of natural hairdye and the colorimetric values were analyzed using the extract of Eclipta prostrata L., which has been used to produce natural coloring material for a long time in Korea, with various mordanting agents and coloring methods.<BR>&nbsp;&nbsp;The colorimetric values depending on mordanting agents were as follows. Colors in NaCl and KAl(SO4)2ㆍ12H2O were showed similar to the ones in non-mordanting group. The color of the hair dyed with FeO and CuO mostly became to dark with low chromaticity. Especially, when hair was dyed with FeO as mordanting agent, the color became to almost black regardless of mordanting method.<BR>&nbsp;&nbsp;The experimental results depending on the mordanting methods were as follows. The hair colors in post-mordanting method was darker than those in pre-mordanting method. When it comes to processing time, the longer time produced the better quality.
