Vintage and Thrift Clothing — Residual Mothball Chemicals (Naphthalene Vapor Absorption, Paradichlorobenzene, Hemolytic Anemia Risk in G6PD-Deficient Individuals) — safety profile
Moderate riskVintage and thrift clothing frequently carries residual mothball chemicals — primarily naphthalene (traditional mothballs) and paradichlorobenzene (1,4-dichlorobenzene, modern mothballs) — absorbed into fabric fibers during prolonged storage.
What is this product?
Vintage and thrift clothing frequently carries residual mothball chemicals — primarily naphthalene (traditional mothballs) and paradichlorobenzene (1,4-dichlorobenzene, modern mothballs) — absorbed into fabric fibers during prolonged storage. Naphthalene, an IARC Group 2B possible carcinogen, sublimes from solid mothballs and adsorbs deeply into wool, cotton, and synthetic fibers, with off-gassing continuing for weeks to months after removal from storage. Critically, naphthalene causes acute hemolytic anemia in individuals with glucose-6-phosphate dehydrogenase (G6PD) deficiency, an X-linked enzyme deficiency affecting 400 million people globally (8-15% of African American males, 10-20% of Mediterranean/Middle Eastern populations). G6PD-deficient infants have died from hemolytic crisis triggered by naphthalene-treated clothing and bedding. Paradichlorobenzene (PDCB), while less acutely toxic, is an EPA-classified possible carcinogen (Group C) and causes liver and kidney damage in chronic animal studies. Both compounds are volatile organic compounds (VOCs) that continue to off-gas at room temperature, creating indoor air quality concerns when vintage clothing collections are stored in closets or bedrooms.
