Analysis of artificial organic colors in cosmetics. II. Nail lacquers. Etournaud, A.; Aubort, J. D. (Lab. Cantonal, Epalinges-Lausanne CH-1066, Switz.). Mitt. Geb. Lebensmittelunters. Hyg., 75(2), 221-6 (French) 1984. CODEN: MGLHAE. ISSN: 0026-6841. DOCUMENT TYPE: Journal CA Section: 62 (Essential Oils and Cosmetics) Nail polish was extd. with DMF in the presence of H3PO4, and the dyes were sepd. into 3 groups by chromatog. on a polyamide column with DMF-H2O (1:1) to elute basic compds., MeOH to elute N-contg. nonionic dyes, and MeOH-NH4OH () to elute sulfonic and carboxylic acids and anionic compds. The basic compds. are extd. with CHCl3 and identified by spectrometry; the other compds. are identified by TLC (Etournaud, A.; Aubort, J. D., 1983). Of the 40 polishes examd., Lithol Rubine BK [5858-81-1] was found in 32, Lithol Bordeaux R [21416-46-6] in 30, tartrazine [1934-21-0] in 20, Permanent Red BB [7585-41-3] in 10, and Rhodamine B [81-88-9] in 3.
