摘要

2-Amino-3-nitrophenol, 2-amino-4-nitrophenol, 2-amino-5-nitrophenol, 4-amino-3-nitrophenol, 4-amino-2-nitrophenol, 2-amino-4-nitrophenol sulfate, 3-nitro-p-hydroxyethylaminophenol, and 4-hydroxypropylamino-3-nitrophenol are substituted aromatic compounds used as semipermanent (nonoxidative) hair colorants and as toners in permanent (oxidative) hair dye products. All ingredients in this group except 2-amino-4-nitrophenol sulfate, 2-amino-5-nitrophenol, and 4-amino-2-nitrophenol have reported uses in cosmetics at use concentrations from 2% to 9%. The available toxicity studies for these amino nitrophenol hair dyes did not suggest safety concerns except for the potential carcinogenicity and mutagenicity of 4-amino-2-nitrophenol. 2-Amino-3-nitrophenol, 2-amino-4-nitrophenol, 2-amino-4-nitrophenol sulfate, 2-amino-5-nitrophenol, 4-amino-3-nitrophenol, 3-nitro-p-hydroxyethylaminophenol, and 4-hydroxypropylamino-3-nitrophenol are safe as hair dye ingredients in the practices of use and concentration as described in this safety assessment, but the data are insufficient to make a safety determination for 4-amino-2-nitrophenol.
