Formaldehyde and chemicals that release formaldehyde are commonly found in cosmetic products like nail polish, eyelash glue, shampoo, and hair gel. People can be exposed to these chemicals every time they use these products – and formaldehyde is known to cause cancer in humans. 

Washington’s Toxic-Free Cosmetics Act regulates many toxic chemicals in cosmetics, including formaldehyde. Under this law, the state’s Department of Ecology is now proposing a rule to restrict 28 additional formaldehyde-releasing chemicals in cosmetics made, sold or distributed in Washington. 

In cosmetics, these chemicals are typically used as preservatives. In hair smoothing or straightening treatments, formaldehyde releasers are found in high concentrations and using these products involves heating both the chemicals and hair. Applying heat releases more formaldehyde into the air, where it can be inhaled.  

Shari Franjevic, Ecology’s implementation lead for the law, notes that some people are exposed more than others.  

“Formaldehyde-releasing chemicals are a special concern because they’re in many cosmetic products routinely used by women, people of color and cosmetologists, increasing their exposure to harmful chemicals,” said Franjevic. 

In addition to cancer, formaldehyde can harm brain function, increase risk of asthma, irritate eyes and skin, and cause allergic reactions.  

Provide input 

Public comment on the proposed rule opens 12 a.m., Feb. 6, 2025, and ends 11:59 p.m., April 11, 2025.  

Interested parties and the public are invited to comment on the proposed rule, economic analysis, environmental impact analysis and an implementation plan for the cosmetics law. The plan describes Ecology’s intended approaches for educating regulated businesses about the law and raising awareness among people more likely to experience higher exposures to toxic chemicals in cosmetics.

Washington’s Toxic-Free Cosmetics Act reduces human and environmental exposure to toxic chemicals by restricting certain chemicals and supporting businesses in reformulating and certifying products and switching to safer alternatives. For more information, visit ecology.wa.gov/TFCA.
