Washington State has adopted a comprehensive ban on formaldehyde and formaldehyde-releasing chemicals in cosmetics. This initiative, under Chapter 173-339 WAC, aims to protect consumers and workers from the potential health hazards associated with these substances, including cancer, respiratory problems, and skin irritation.

The new rule, formally known as “Formaldehyde in Cosmetics Rulemaking (339A),” identifies 25 specific formaldehyde-releasing chemicals that will be restricted when intentionally added to cosmetic products. This proactive measure is expected to encourage manufacturers to innovate and reformulate their products, leading to a safer market for consumers.

Key Provisions and Impact:

  • The rule explicitly restricts 25 formaldehyde-releasing chemicals when intentionally added to cosmetics.
  • The rule clarifies the definition of “intentionally added” within the context of the Toxic-Free Cosmetics Act, ensuring that all chemicals releasing formaldehyde are restricted when formaldehyde serves an intended function in the product.
  • The restrictions will impact cosmetic manufacturers, distributors, retailers, and cosmetology businesses operating in Washington State. It also applies to cosmetic products used in services, sold online, and sold in physical stores.

Timeline for Implementation:

  • Rule Adoption: August 28, 2025
  • Rule Takes Effect: September 28, 2025
  • Restrictions Take Effect: January 1, 2027
