That fresh pine scent may be harming your health and polluting the environment. A study of 25 scented products—from air fresheners and dryer sheets to deodorants, shampoos, and hand sanitizers—found that they collectively emitted more than 100 volatile organic compounds, reports Environmental Health Perspectives.
Specifically, University of Washington researchers found 133 VOCs in the 25 products, according to EHP, with the most common chemicals being the familiar limonene (citrus) and pinene (pine) scents. They also found lots of ethanol and acetone, which are used as carriers for fragrance chemicals.
Here are some of the more surprising findings about the 133 compounds:
• 24 of them are classified as toxic or hazardous under federal law.
• Only one was listed on any product label.
• Only two were listed on any of the products’ material safety data sheets, the more detailed—but hardly comprehensive—disclosure forms required by federal law.
• Some of the products were labeled “organic,” “natural” or “non-toxic.”
So yes: That cleaner with the searing pine scent, the dryer sheet with the cloying perfume smell, the soap with the faux-almond aroma that doesn’t go away even when you rinse your hands—these probably aren’t making your world “fresher” and “cleaner” but rather more polluted and unhealthy.
Lead author Anne Steinemann tells Emily Sohn at Discovery News that scented-product labels can be misleading:
“ ‘Natural’ does not mean no synthetic chemicals. ‘Green’ does not mean safe or healthy. ‘Fragrance-free’ does not mean nontoxic or without fragrance. There are a lot of paradoxes and surprises here.”
Last year, Sen. Al Franken introduced the Household Product Labeling Act, which would have required manufacturers to list all a product’s ingredients on it labels, but the bill didn’t even make it past the committee stage. So no legislative crackdown appears imminent, but in the meantime, one expert contacted by EHP suggests a change in our mindset:
Steinemann’s study “strongly suggests that we need to find unscented alternatives for cleaning our homes, laundry, and ourselves,” says Claudia Miller, an allergist and immunologist at the University of Texas Health Science Center at San Antonio.
