Where It Comes From
Dyeing/printing of synthetic textiles; release from textile mills to wastewater; residue on new clothes and synthetic blends [1][3].
How You Are Exposed
Skin contact with dyed clothing (especially new, tight, or sweaty garments); workers may contact dye powders, mists, or dyed materials [1][2][3].
Why It Matters
Classified as a skin sensitizer that can cause allergic contact dermatitis; azo dyes can also affect aquatic environments when discharged [1][3].
Who Is at Risk
Textile and dye-house workers; people with eczema or known dye allergies; infants/children with sensitive skin; those wearing tight synthetic sportswear or underwear [2][3].
How to Lower Your Exposure
Wash new clothes before wearing; choose natural fibers or light/untreated colors; look for certified low-chemical textiles; avoid prolonged damp contact; workers should use gloves, ventilation, and hygiene practices [1][2][3].
