Formaldehyde, a common chemical
Formaldehyde, one of the most common causes of allergic contact dermatitis, can, unfortunately, be found as a pervasive chemical in our everyday environment. Although I wasn’t exposed to formaldehyde in a work environment, many find themselves becoming sensitized to formaldehyde in a work situation. Formaldehyde is a prominent allergen and is commonly diagnosed as an Allergic Contact Dermatitis allergy.
Formaldehyde in the workplace
Formaldehyde can affect the body of those who work with it. Workers in multiple industries find formaldehyde a part of their everyday work lives. Workers in the embalming and mortuary business are an obvious culprit for formaldehyde exposure. Workers in a lab setting and the plastic, wood, and paper industry can also find formaldehyde and its releases in their workplace. Textile and metal workers, as well as machinists, also could become sensitized in a work environment.
Formaldehyde as a preservative
Formaldehyde is a very common preservative used in cosmetic and personal care products. While you’ll never find “formaldehyde” listed as an ingredient, it is lurking in several ingredient names as a chemical that can release formaldehyde. Look for these ingredients that are formaldehyde releasers and avoid them: dimethyl urea, Quaternium-15, imidazolidinyl urea, Diazolidinyl Urea, Bronopol, DMDM hydantoin. By avoiding these preservatives, you’ll go a long way in reducing your exposure.
Is formaldehyde in my clothes?
Another area of concern for those sensitized to formaldehyde is clothing. So consequently, Formaldehyde resins can show up in blended fabrics such as cotton/rayon blends or cotton/polyester blends. I notice this mostly in my socks of all places. These resins can stay with some blended fabrics even when washed. Consequently, washing doesn’t always make an item safe. When I try to wear a sock with a resin, my body immediately notices it, and I have to remove them. Finding socks has been a real challenge.
Wearing clothes that contain formaldehyde resins can cause a flare-up of allergic contact dermatitis.
Avoid these clothes and finishes
- permanent press
- anti-cling finishes
- anti-static finishes
- chlorine resistant finishes
- stiffening or anti-curl finishes on lightweight knits
- waterproof finishes
- perspiration proof finishes
- mothproof finishes
- mildew resistant fabrics
- screen printed fabrics
While this seems like a lengthy list, formaldehyde-sensitive individuals can usually successfully wear clothing made from a single fiber such as 100% cotton, polyester, silk, nylon, or wool.
Other Possible Exposures Include:
Glues (school glues and others)
Formaldehyde is a component of smoke from burning wood, coal, charcoal, cigarettes, and cigars.
