Washington has joined more than a dozen other states in seeking to crack down on toxic substances in cosmetics after a state-funded study there found lead, arsenic, and formaldehyde in makeup, lotion, and hair-straightening products made by CoverGirl and other brands.
The U.S. stalled out on chemical regulations after the 1970s, according to Bhavna Shamasunder, an urban and environmental policy associate professor at Occidental College. And that has left a regulatory void, as lax federal oversight allows potentially toxic products that would be banned in Europe to be sold in American stores.
