The EU Endocrine Disruptor (ED) Assessment List is maintained by the European Chemicals Agency (ECHA) and serves to include substances that are undergoing assessment for endocrine-disrupting properties. Since February 2013, any substance considered to have or potentially have endocrine-disrupting properties has been included in the list. As of the latest update date, 27 April 2026, the list contains a total of 138 unique substances/entries.
The list comprises substances that have been submitted to the ECHA Endocrine Disruptor Expert Group for discussion. These substances are undergoing an informal hazard assessment to determine whether they possess endocrine-disrupting characteristics. The outcome of the assessment may indicate that a substance does not have endocrine-disrupting properties; however, if the assessment concludes that a substance does have such properties, formal risk management and decision-making processes must be followed to confirm these characteristics before any regulatory actions can be taken based on these properties.
- A new substance added for assessment:
| Substance name | CAS No. | EC No. | Status | Outcome |
