11 substances were added to the EU Endocrine Disruptor Assessment List-Feb 27,2026

The European Union's Endocrine Disruptor Assessment List is a registry maintained by the European Chemicals Agency (ECHA), which includes substances that are undergoing assessment for endocrine-disrupting properties. The latest update to this list was on 18 February 2026, and it contains 137 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.

Main updates:

• 1 substance name revised: Mono- and di-ortho-phthalate esters with at least one of the following: - a linear or branched alkyl moiety with a C4-C6 backbone* with possible substitution by methyl and/or ethyl groups; - a benzyl moiety with methylene possibly substituted by methyl and/or ethyl groups; - a cyclopentyl or cyclohexyl moiety with possible substitution by methyl and/or ethyl groups. [*The backbone is defined as the longest linear carbon chain from the ester function]
• Assessment status/outcome revised for 4 substances:
  1. 3-phenoxybenzyl-2-(4-ethoxyphenyl)-2-methylpropyl ether;
  2. Oxybenzone;
  3. Geraniol;
  4. 4,4'-isopropylidenedi-2,6-xylol
• 11 new substances added for assessment:

Since February 2013, any substance deemed to have or potentially have endocrine-disrupting properties has been included in this list.
