Washington state is continuing implementation of its Toxic-Free Cosmetics Act (TFCA), which establishes restrictions on certain chemicals in beauty and personal care products to reduce exposure to toxic substances.
The state’s restrictions on formaldehyde and methylene glycol in cosmetics took effect Jan. 1, 2025, under Chapter 173-339 WAC. Products containing these chemicals were subject to a sell-through period that ended Dec. 31, 2025, meaning cosmetics currently sold or used in Washington cannot contain formaldehyde or methylene glycol. These chemicals are commonly found in some hair straightening and smoothing treatments.
Additional restrictions on formaldehyde releasers will begin Jan. 1, 2027. Washington became the first state to adopt a comprehensive ban on intentionally added formaldehyde-releasing chemicals in cosmetics. The requirements apply to manufacturers, distributors, retailers, and cosmetology businesses, including products sold online, in stores, or used in professional services.
The upcoming restrictions cover 25 intentionally added formaldehyde-releasing chemicals. Retailers and other businesses are encouraged to review product labels, research ingredients that may not be clearly identified on packaging, and evaluate their supply chains to determine whether affected products are present.
The Washington Department of Ecology has updated its TFCA guidance materials to help businesses understand restricted chemicals, compliance timelines, and steps needed to prepare. The updated guide provides information for companies that manufacture, distribute, sell, or use cosmetic products in Washington.
Businesses can review the Toxic-Free Cosmetics Act resources and compliance guidance through the Department of Ecology to prepare for the 2027 requirements and ensure affected products are addressed before the restrictions take effect.
