Potential candidates for TCO Certified Accepted Substance List

This list presents substances that have been previously reviewed by toxicologists. Their assessments indicate that the substances may be classed as safer alternatives. However, to be added to TCO Certified Accepted Substance List, an updated assessment must be made.

Before a substance is added to TCO Certified Accepted Substance List, it must receive a benchmark score of 2, 3, or 4, or a ChemForward hazard band A, B or C set by an independent Licensed Profiler and the assessment report must be submitted to TCO Development. If you are interested in seeing a substance added to TCO Certified Accepted Substance List or the potential candidate list, contact TCO Development or the profiler organization.
