Conclusion on classification

The environmental classification of DMDEE is currently not harmonized according to the CLP Regulation (EC) 1272/2008 and the Dangerous Substance Directive 67/548/EC.

Based on available acute toxicity data, the lowest valid effect concentration for freshwater aquatic organisms

> 100 mg/L. Long-term studies are not available. Based on these results and although the test substance is not readily biodegradable, it should not be classified for Acute or Chronic toxicity for the aquatic environment according to Annex 1 (section 4.1.2.6) of the CLP Regulation. Based on the same criteria the substance should not be classified for the environment under the Dangerous Substance Directive 67/548/EC (see Annex VI section 5.2.1.2).
