A nasty ingredient in no-iron shirts

Have you ever caught a suspicious whiff of a wrinkle-free shirt?<br />

Is there formaldehyde in no-iron shirts? I got a whiff the other day of my husband’s shirts. For now the shirts are quarantined. Not sure if I should donate them or take them to the hazardous waste depot with the paint cans.

Your suspicion about formaldehyde in no-iron shirts, also known as wrinkle-free, is spot on. To be sure, you could write to the company and see if they disclose the chemical treatment or hide behind proprietary rights.


I hate to iron as much as the next person, but to make cotton iron-free, the fabric is typically soaked in formaldehyde. When you press it flat it becomes wrinkle-resistant. Retailers warn that due to the change in molecular structure of the cotton shirt, the fabric becomes more brittle. This means the life expectancy of your husband’s no-iron shirt may be cut by 25 per cent.


If a short lifespan isn’t discouragement enough (you want to stretch every dollar, after all), these low-maintenance duds are impregnated with a cancer-causing chemical. Formaldehyde is found in more than no-iron shirts. It’s used in a host of consumer products like air fresheners, nail polish, bed sheets, kitchen cabinets, carpets, furniture – you get the idea.


Since formaldehyde is known to emit fumes from products and can be inhaled -- most of the cancer research on formaldehyde has focused on risks from inhalation – avoid it. Off-gassing of formaldehyde from building products, for example, is a concern for indoor air quality. Health Canada recommends the reduction or elimination of as many sources of formaldehyde as possible.
