Key value for chemical safety assessment

Additional information

No data are available investigating the toxicity of Fatty acids, C18 unsaturated, trimers, 2-ethylhexyl esters (CAS No. 173832-46-7) to terrestrial plants.

The test substance is characterized by a high log Koc (>5) indicating a potential for adsorption to the soil particles. Tests with soil-dwelling organisms that feed on soil particles are therefore most relevant for the evaluation of soil toxicity of the category members. In the absence of a clear indication of selective toxicity, an invertebrate (earthworm or collembolan) test is preferred, as outlined in ECHA guidance section R.7.11.5.3 (ECHA 2012). 

Therefore, a study according to OECD 222 (earthworm test) investigating the long-term toxicity is proposed. The dossier will be updated as soon as possible and the Chemical Safety Assessment according to Annex I of Regulation (EC) No 1907/2006 will be re-evaluated based on the outcome of the new studies.
