A study from the University of Washington (UW) found that chemicals with potential toxicity or health hazards are being used in top selling laundry products and air fresheners, and they are not listed on any product labels that were tested.
"Be careful if you buy products with fragrance, because you really don't know what's in them," said Anne Steinemann, a UW professor of civil and environmental engineering and public affairs "I'd like to see better labeling. In the meantime, I'd recommend that instead of air fresheners people use ventilation, and with laundry products, choose fragrance-free versions."Steinemann noted that the European Union recently enacted legislation requiring products to list 26 fragrance chemicals when they are present above a certain concentration in cosmetic products and detergents. No similar laws exist in the US.
