Cancer Claims Linked to Household Items

These days, it seems like you can find articles online suggesting that yet another everyday item might cause cancer. The latest items under scrutiny? Fabric softeners and dryer sheets—those familiar goodies we use when tackling laundry.

The science behind claims that these products contain cancer-causing chemicals is more complicated than it appears at first glance.

For starters, it’s worth noting that dryer sheets and liquid softeners themselves are not intended to harbor ingredients known to be carcinogenic. They might, however, release volatile organic compounds (VOCs) into the air, which can pose health risks over time. Consumers should particularly keep an eye on fragrance components, impurities, or byproducts that may arise during manufacturing.

A couple of studies—one from 2011 and another from 2016—found that VOCs were emitted from dryer vents when fragranced laundry products were used. Alarmingly, substances like acetaldehyde and benzene identified in those emissions are classified as hazardous air pollutants by the EPA.

However, it’s important to point out that further research hasn’t confirmed whether these emissions have a direct link to cancer in humans.

Many everyday laundry products contain various blends of VOCs; two common offenders are phthalates, often found in fragrant items, and benzyl acetate, frequently used for its floral scent. Phthalates are known to disrupt endocrine hormones, like estrogen and testosterone, which could lead to reproductive or developmental issues.

A review of studies indicates that chemicals found in scented products may be associated with health concerns, including cancer, but we still need more evidence to fully understand these connections.

Manufacturers often group several chemicals under the term “fragrance” or “perfume” on labels. This can lead to exposure to complex chemical cocktails that might not be immediately apparent.

It’s also notable that unlike detergents, which rinse out, fabric softeners cling to clothing. This results in two types of exposure: inhaling vapors and direct skin contact as clothes touch our skin.

While there isn’t substantial evidence tying dryer sheets and fabric softeners directly to cancer, a degree of risk remains. Experts emphasize that the risk can depend on factors like how often you use these products, the amount, and how long you’re exposed to them.

“Because fragrance emissions aren’t always easy to identify on labels, many medical professionals suggest reducing unnecessary fragrance exposure when possible,” explained Dr. Krushangi Patel, a medical oncologist from City of Hope.
