Chapter 173-339 WAC – Cosmetic Products Restrictions

The Washington Department of Ecology (Ecology) started a rulemaking to develop a new chapter in the Washington Administrative Code (WAC): Chapter 173-339 WAC—Cosmetic Products Restrictions. Ecology is conducting this rulemaking to:

  • Make cosmetics safer for consumers and the environment.
  • Reduce consumers’ and workers’ exposure to formaldehyde.
  • Address the disproportionate harms caused by cosmetic products in overburdened communities and vulnerable populations.
  • Reduce the amount of formaldehyde entering the environment.

Under the authority of Chapter 70A.560 RCW (Toxic-Free Cosmetics Act), Ecology may adopt a rule that identifies chemicals used in cosmetic products that release formaldehyde (formaldehyde releasers) and adopt restrictions for the identified formaldehyde releasers. This rule may include:

  • Restrictions that apply to the use of specified formaldehyde releasers used in cosmetic products.
  • Allowances for products currently in the chain of commerce—stockpiled or available for purchase.
  • Compliance schedules.
  • Definitions of key terms such as “intentionally added.”
  • Other requirements or restrictions allowed by law.
