Expert Panel for Cosmetic Ingredient Safety:
The safety of 2-methyl-5-hydroxyethylaminophenol has been assessed by the Expert Panel for Cosmetic Ingredient Safety. The Expert Panel evaluated the scientific data and concluded that 2-methyl-5-hydroxyethylaminophenol was safe as a cosmetic ingredient in the present practices of use and concentration.
2-methyl-5-hydroxyethylaminophenol was neither a mutagen nor a developmental toxicant, and only a small amount of it was absorbed through the skin. Studies in this report indicated that oxidative hair dyes containing this ingredient may induce skin irritation and sensitization. Therefore, persons using hair dye products should minimize exposure to the skin.
