It is reported that commercial lip stick's pigment of six samples by This layer chromatography. From these samples Red 3, Red 223, Red 218 and Yellow 4 were investigated. As a result of the experiment, we found that components of pigments of these lip stick samples are generally lakes of fluorescenes.
