Abstract
Generally, the glossness of the lipstick is evaluated by human visual judgment. We irradiated the surface of the lipstick with the light of various wavelengths which was controlled by the band-pass-filter and measured the reflectance from the surface. As for the specimen of lipstick, it was turned to change an irradiation position, and, uneven coloring of the lipstick was evaluated by a change of the reflectance. The evaluation by the light reflectance from lipstick surface accorded with a judgment by the human visual well.Key Words :
