|
In manufacture of the first formulated type of acidic hairdye among various hairdyes. this study is aimed not only at grasping dying power of the first formulated type of acidic hairdye and PH necessary for surely in case of manufacturing of hairdye by dyeing sample with the first formulated type of acidic hairdye that has been produced by adding ingredient content that can improve dyeing power of the first formulated type of acidic hairdye after adding a kaoliang pigment as a ingredient of natural pigment, In research methods, we have searched for brightness index L* as a color tone value and chromaticity index, a*- b* value and dye uptake(K/S) after we produced a hairdye and dried naturally for 20 minutes, again 40 minutes, and treat by heating for 10 minutes and treated to leave a hairdye as it is naturally. Result that we have analyzed in comparison with L*, a*, b*value of kaoliang pigment as a natural pigment (colorant) and K/S value is satisfactory as an ingredient of the first formulated type of hairdye, because dyeing power is not only more excellent than untreated hair, but also dyeing power is much more excellent in case of heat treatment than in case of treatment to leave a hairdye as it is naturally when a person dyes his hair. We could have grasped that (it is) not that dyeing power heighten more because of addition of more pigment dissolvent (dissolving agent), (it is) but that dyeing power heighten when pigment dissolvent is mixed up with pigment content at a proper rate.
