To increase transparency and speed up the transition to safer chemicals, TCO Development now introduces a public list of candidates to TCO Certified Accepted Substance List.

The potential candidates list presents chemical names, the CAS numbers and the profiler organisations of substances that have been previously reviewed by toxicologists. Their assessments indicate that the substances may have the potential to be classed as safer alternatives.

However, to be added to TCO Certified Accepted Substance List, an updated assessment must be carried out by a Licensed GreenScreen Profiler. The substance must receive a benchmark score of 2, 3, or 4 and the assessment report must be submitted to TCO Development. If a substance has been assessed in accordance with a chemical hazard assessment framework other than GreenScreen, it must be converted to GreenScreen.

If you are interested in seeing a substance added to TCO Certified Accepted Substance List or the potential candidate list, contact Stephen Fuller, Senior Criteria Manager at TCO Development, or the profiler organization.
