Abstract: The article presents the experimental data concerning the synthesis of some disazoic dyes which are the result of the condensation of monoazoic dyes obtained in their turn by the diazotation of amines: para-nitroaniline, N,N-dietil-aminoaniline, 3-nitroaniline, 2-amino-4-metilphenol, acid 4-aminonaphtaline-1-sulphonic acid and the coupling with BON acid. The synthesised cosmetic dyes have been purified and characterized through elemental analysis, chromatography and IR spectra. The yields vary between 60-80 %. These compounds have been used in the coloring of lipsticks and nail varnish, and pharmacological tests were made. The experimental data show good results.
