Do wrinkle-free shirts contain formaldehyde?
Be cautious with new furniture. Formaldehyde off-gasses from pressed wood and finishes. Ventilate rooms.
What's actually in it
Formaldehyde is a colorless gas used in pressed wood products, glues, and fabric treatments. Furniture made from particleboard or MDF (medium-density fiberboard) releases formaldehyde as gas for months to years after manufacture.
Some wrinkle-resistant clothing treatments also use formaldehyde-based resins. Indoor levels are often higher than outdoor levels because of trapped off-gassing.
