1-Amino-2-methylanthraquinone

Made and used in dye manufacturing; can be present in textile-dyeing effluent and from wear/shedding of dyed synthetic fibers [3][4].

Workers may breathe dust or have skin contact during production and dyeing; the public mainly through skin contact with dyed polyester/plastic items and indoor dust [3][4].

Specific human data are scarce. The related parent compound anthraquinone causes cancer in animals and is classified by IARC as possibly carcinogenic (Group 2B) and by NTP as reasonably anticipated to be a human carcinogen; some anthraquinone dyes can irritate skin/eyes [1][2][3].

Dye and textile workers; people with skin allergies who wear new, deeply dyed synthetics; young children who mouth dyed plastics [3].

At work, use ventilation, enclosed handling, and PPE. At home, wash new synthetic clothes before wearing, choose certified/colorfast textiles, clean dust with wet methods/HEPA, and discourage mouthing of dyed plastics [3][4].
