On Août 25, 2025, Washington State adopted a new rule, Chapter 173-339 WAC, to restrict the manufacture, sale, and distribution of cosmetic products in Washington State that contain intentionally added formaldehyde and chemicals that release formaldehyde. The restrictions will take effect on Janvier 1, 2027 and retailers may sell existing stock through Décembre 31, 2027.
The rule identifies 25 formaldehyde-releasing chemicals that are restricted when intentionally added to cosmetic products, and also defines ‘intentionally added’ to clarify the applicability of restrictions on toxic chemicals in the Toxic-Free Cosmetics Act (RCW 70A.560.020). Applying the definition of ‘intentionally added’ to the statutory restriction on formaldehyde restricts all chemicals that release formaldehyde when the formaldehyde serves an intended function in the cosmetic product, or an ingredient in the cosmetic product.
The restrictions in rule and in the Toxic-Free Cosmetics Act:
- Affect cosmetics manufacturers, distributors, retailers, and cosmetology businesses operating in Washington State.
- Apply to cosmetic products used in services, sold online, and sold in physical stores.
More information regarding the adopted rule, including the list of 25 formaldehyde-releasing chemicals that are restricted, can be found on the Department of Ecology (DoE) website.
