ABSTRACT

Thin-layer (uni-dimensional and bi-dimensional) chromatography studies were performed on 52 beige stockings and pantyhose from different countries. They demonstrated the presence of Disperse Yellow 3 in 51 and Disperse Orange 3 in 15 stockings. In the absence of isolation and spectroscopic identification of the dyes, these results are strong clues to their presence.
