TCO Certified Accepted Substance List

Substances listed by CAS number or Trade name are approved for use in certified products and their manufacture. You can filter the list by clicking on the purple header bar or by using the search field to the right.

GreenScreen benchmarks and ChemForward hazard band assessments are valid for up to five years from the date shown under ‘Assessed’. TCO Certified Accepted Substance List is dynamic and substances may be reassessed in light of new scientific findings. A substance must be reassessed before the expiry date (shown under ‘Approaching expiration date’), otherwise the substance will be moved to the potential candidate list and can no longer be used for certified products.

How our accepted list works

Reduce risk and identify a pathway to safer options with TCO Certified.

Potential candidates list

Find substances previously approved as safer by independent toxicologists.

Comments
  1. Interchangeable CAS numbers
  2. Assessment is freely available here
  3. Assessment is freely available here
  4. Trade name specific benchmark in accordance to polymeric criteria in GreenScreen v1.4. Other trade names for the same CAS# number must provide a separate GS assessment since any relevant production impurity can impact the final benchmark.
  5. Expired assessment report. A valid assessment report confirming a compliant benchmark or hazard band must be received before the sunset date for this substance to remain accepted.
  6. Trade name-specific cleaning product (CP) independently assessed to GreenScreen Certified™ Cleaners & Degreasers. Gold and Platinum levels require each chemical in the product to be assessed with GreenScreen for Safer Chemicals and be scored Benchmark 2 or higher. To remain listed, the certification must be updated every third year.
