From tires to nail polish, we’re studying a new round of consumer products with toxic chemicals

Draft report open for formal public comment

In May 2024, our Safer Products for Washington team identified a new set of toxic chemicals in everyday consumer products. That’s important because it gives us an opportunity to reduce exposure to toxic chemicals and prevent their release into the environment. We want your feedback on the products we’ve identified as significant sources of these toxic chemicals.

DOE – 6PPD

6PPD stands for the chemical N-(1,3-dimethylbutyl)-N’-phenyl-p-phenylenediamine. It’s a chemical that prevents automotive tires from degrading (i.e., breaking down) and helps them last longer. When 6PPD is exposed to air, it reacts with ozone to create 6PPD-quinone (also known as 6PPDQ). 6PPDQ is lethal to coho salmon and can contaminate water systems.
