 Study Says Scented Laundry Products, Air Fresheners Contain Toxic Chemicals

Researchers at the University of Washington have found toxic chemicals in the commodities like top-selling laundry products and air fresheners.

All six products tested in the research gave off at least one chemical regulated as toxic or hazardous under federal laws, but none of those chemicals was listed on the product labels, the study found.

"I first got interested in this topic because people were telling me that the air fresheners in public restrooms and the scent from laundry products vented outdoors were making them sick," said Anne Steinemann, a UW professor of civil and environmental engineering and of public affairs.

"And I wanted to know, 'What's in these products that is causing these effects?'" she added.

In the research, Anne analyzed the products to discover the chemicals' identity.

"I was surprised by both the number and the potential toxicity of the chemicals that were found," Steinemann said.

Chemicals included acetone, the active ingredient in paint thinner and nail-polish remover; limonene, a molecule with a citrus scent; and acetaldehyde, chloromethane and 1,4-dioxane.

"Nearly 100 volatile organic compounds were emitted from these six products, and none were listed on any product label. Plus, five of the six products emitted one or more carcinogenic 'hazardous air pollutants,' which are considered by the Environmental Protection Agency to have no safe exposure level," Steinemann said.

The study has been published online today by the journal Environmental Impact Assessment Review.

Steinemann chose not to disclose the brand names of the six products she tested.

In a larger study of 25 cleaners, personal care products, air fresheners and laundry products, now submitted for publication, she found that many other brands contained similar chemicals.

Because manufacturers of consumer products are not required to disclose the ingredients, Steinemann analyzed the products to discover their contents.

She studied three common air fresheners (a solid deodorizer disk, a liquid spray and a plug-in oil) and three laundry products (a dryer sheet, fabric softener and a detergent), selecting a top seller in each category. She bought household items at a grocery store and asked companies for samples of industrial products.

In the laboratory, each product was placed in an isolated space at room temperature and the surrounding air was analyzed for volatile organic compounds, small molecules that evaporate from the product's surface into the air.

Results showed 58 different volatile organic compounds above a concentration of 300 micrograms per cubic meter, many of which were present in more than one of the six products.
