Azo dyes, extensively used for coloring a variety of consumer goods, such as leather, clothes, food, and toys, can under certain conditions be reduced to form confirmed or suspected carcinogenic aromatic amines. This article gives an overview of the state of development of analytical procedures for the determination of such azo dyes, which are banned by the European Commission.read more

Structure–properties relationships investigation on the azo dyes derived from benzene sulfonamide intermediates
TL;DR: In this paper, the properties of derived azo dyes derived from azo intermediates were characterized by FTIR, MS and 1H NMR, which revealed that their molecular configuration is non-planar.

Simultaneous determination of 11 restricted dyes in cosmetics by ultra high-performance liquid chromatography/tandem mass spectrometry
TL;DR: In this article, a simple, fast, and sensitive method was developed for the simultaneous determination of 11 restricted water-soluble colorants (including Tartrazine, Amaranth, Ponceau 4RC, Sunset Yellow, Allura Red AC, Acid Red 2G,Ponceau SX, Brilliant Blue FCF, Orange I, Acid Black 1, and Acid Orange 7) in eye shadow, lipstick, lip gloss, and other cosmetics by using ultra-high performance liquid chromatography/tandem mass spectrometry.

Comments on the history and importance of aromatic and heterocyclic amines in public health.
TL;DR: Investigation on the mode of action of this class of chemicals, identified as heterocyclic amines (HCAs), found that HCAs induced cancer in rats in these organs and also in the prostate and the pancreas, and there is some evidence that they affect the vascular system.

TL;DR: The consistent observation of a difference between men and women in bladder cancer risk, after allowing for known risk factors, suggests consideration of gender-related biological determinants for future investigation.

Mutagenicity of azo dyes used in foods, drugs and cosmetics before and after reduction by Clostridium species from the human intestinal tract
TL;DR: No mutagenicity was induced in either TA98 or TA100 by any of the seven azo dyes or the reduced metabolites when tested at concentrations as high as 200 microg/plate, with or without exogenous metabolic activation by rat liver fraction S-9.

Formation of a carcinogenic aromatic amine from an azo dye by human skin bacteria in vitro.
TL;DR: The ability to cleave azo dyes seems to be widely distributed among human skin bacteria, as, under these in vitro conditions, bacteria isolated from healthy human skin and human skinacteria from strain collections also exhibited azo reductase activity.

Mutagenicity and carcinogenicity of aromatic amines metabolically produced from Azo Dyes
TL;DR: In this article, the authors investigated the carcinogenicity of aromatic amines metabolically produced from Azo Dyes and found that they are mutagenous and carcinogenous.
