As of January 1, 2025, the Washington State Toxic Free Cosmetics Act restricts the use of certain toxic chemicals in cosmetic and personal-care products sold within the state. The goal of this law is to reduce consumer exposure to hazardous substances and improve overall cosmetic safety. Any manufacturer selling covered products in Washington must ensure compliance before distribution.
The regulation applies to a wide range of products, including makeup, skincare, haircare, fragrances, and other personal-care items. Both U.S. and international brands are subject to these requirements if their products enter the Washington market.
Washington State Toxic Free Cosmetics Act Compliance Requirements
Under the Act, Washington State restricts nine chemicals identified as posing potential risks to human health or the environment. These substances may be intentionally added ingredients or may appear as impurities due to raw materials, pigments, or manufacturing processes.
One area of particular concern is heavy metal contamination, including lead. Lead is a toxic metal that can accumulate in the body over time. Prolonged exposure may increase the risk of neurological, developmental, and reproductive effects. Even trace amounts can create regulatory and safety concerns when present above allowable limits.
Because contamination can occur unintentionally, manufacturers must take proactive steps to verify product safety.
Role of Testing in Cosmetic Compliance
Analytical testing plays a key role in demonstrating compliance with Washington State cosmetic regulations. Testing helps confirm that restricted substances are not present above regulatory thresholds and provides documentation to support compliance decisions.
Common compliance activities include:
- Screening for restricted substances
- Heavy metal analysis
- Raw material verification
- Finished product testing
- Supplier compliance confirmation
Manufacturers often pair this work with our heavy metals testing services to support broader cosmetic compliance programs.
Regulatory Context and Ongoing Compliance
The Washington State Toxic Free Cosmetics Act aligns with broader regulatory trends, including California Proposition 65 and FDA MoCRA requirements. Coordinating testing across multiple jurisdictions can reduce duplication and streamline compliance efforts.
Manufacturers should also monitor updates to restricted substance lists, as regulatory requirements may change over time. For additional regulatory context, review guidance published by the Washington State Department of Ecology. Washington State Department of Ecology cosmetic regulations
