Description of key information

The chemical safety assessment according to Annex I of Regulation (EC) No. 1907/2006 does not indicate the need to investigate further the toxicity to terrestrial plants. 

Key value for chemical safety assessment

Additional information

No experimental data evaluating the toxicity ofFatty acids, C12-16 (even numbered) and C18-unsatd., methyl esters (CAS No. 1234694-02-0) to terrestrial plants are available.


The test substance is characterized by a log Pow > 5 and log Koc > 3, indicating high potential for adsorption to soil particles. Tests with soil-dwelling organisms that feed on soil particles are therefore most relevant for the evaluation of soil toxicity of Fatty acids, C12-16 (even numbered) and C18-unsatd., methyl esters. Soil invertebrates toxicity data from suitable read-across substances (methyl laurate (CAS No. 111-82-0) and methyl palmitate (CAS No. 112-39-0) in accordance with Regulation (EC) No. 1907/2006, Annex XI, 1.5) are available. In these tests performed according to OECD 222, no effects on survival, reproduction or growth of Eisenia fetida were reported, leading to NOEC values = 1000 mg/kg dw (Winkelmann (2013)).


Therefore, in accordance with Regulation (EC) No. 1907/2006, Annex X, Column 2, 9.4 further studies on the effects on terrestrial organisms does not have to be conducted since the chemical safety assessment indicates that there is no need.
