Formaldehyde is IARC Group 1 (carcinogenic to humans — nasopharyngeal cancer via inhalation). New wrinkle-free shirts release 20-200+ ppm formaldehyde. Japan limits formaldehyde in clothing to 75 ppm (adults) and 16 ppm (infants). No US federal limit for formaldehyde in textiles. GAO 2010 report found wrinkle-free shirts at 25-206 ppm formaldehyde. Symptoms: skin irritation, contact dermatitis, respiratory irritation from new-garment off-gassing. Washing reduces formaldehyde 60-80% in first wash.","synthesis":{"derived_risk_level":"insufficient_data","synthesis_confidence":0,"synthesis_method":"none","context_source":null,"compounds_resolved":1,"compounds_total":1,"synthesis_date":"2026-03-27","synthesis_version":"1.0.0"},"hazard_summary":{"sensitive_populations":"formaldehyde-sensitized individuals, infants, textile workers","overall_risk":"moderate","primary_concerns":["Formaldehyde (IARC Group 1) released from wrinkle-free resin finish","No US federal limit for formaldehyde in clothing (Japan: 75 ppm adult, 16 ppm infant)","20-200+ ppm formaldehyde in new wrinkle-free shirts (GAO 2010)","Contact dermatitis in formaldehyde-sensitized individuals"],"exposure_routes":"Dermal (skin contact); inhalation (off-gassing from new garments)"},"exposure":{"routes":["dermal","inhalation"],"contact_types":["skin_prolonged","inhalation"],"users":["adult","child"],"duration":"continuous","frequency":"daily","scenarios":["Wearing new wrinkle-free clothing without pre-washing (20-200+ ppm formaldehyde)","Off-gassing from closet full of permanent press garments","Skin contact dermatitis from formaldehyde resin finish","Textile workers: occupational formaldehyde exposure during finishing"],"notes":"DMDHEU resin: cross-links cellulose fibers, preventing wrinkles.
