Application of systematic evidence mapping to identify available data on the potential human health hazards of selected market-relevant azo dyes

open access: yesEnvironment International, 2023
Background: Azo dyes are used in textiles and leather clothing. Human exposure can occur from wearing textiles containing azo dyes. Since the body’s enzymes and microbiome can cleave azo dyes, potentially resulting in mutagenic or carcinogenic ...

Concentration dependence of thermal isomerization process of methyl orange in ethanol [PDF]

open access: yes, 2017
The thermal isomerization (TI) rates of methyl orange (MO) and 4-dimethylaminoazobenzene (DMAAB) in ethanol (EtOH) are measured. Usually TI rates of azobenzene dyes are known to be concentration independent.
