Description of key information
The chemical safety assessment according to Annex I of Regulation (EC) No. 1907/2006 does not indicate the need to further investigate the toxicity to terrestrial arthropods.
Key value for chemical safety assessment
Additional information
In accordance with Regulation (EC) No. 1907/2006, Annex IX, column 2, 9.4 further studies on the effects on terrestrial organisms are not necessary because the chemical safety assessment does not indicate a need for further investigations.
No experimental data on the toxicity of the target substance target substance Fatty acids, C16, C18 and C18-unsaturated, C12-15 alcohol (linear and branched), esters to terrestrial arthropods are available. The substance is characterized by a high log Koc, indicating a potential for adsorption to soil particles. Therefore, tests with soil-dwelling organisms that feed on soil particles are most relevant for the evaluation of soil toxicity.
In the available earthworm study with the source substance 2-octyldodecyl isooctadecanoate (CAS 93803-87-3), no significant effects on mortality/growth and reproduction of E. fetida were found, resulting in a NOEC (56 d) ≥ 1000 mg/kg soil dw (OECD 222).
Furthermore, no acute and chronic effects were observed in the available aquatic studies. Moreover, exposure of the soil compartment is generally expected to be low because the substance will not persist in the environment due to ready biodegradability. Indirect exposure via irrigation or atmospheric transport is considered negligible based on the physico-chemical properties of the substance (water solubility: < 1 mg/L; vapour pressure: < 0.00001 Pa).
Thus, the available data for the toxicity to terrestrial macroorganisms are sufficient to assess the hazard of the target substance Fatty acids, C16, C18 and C18-unsaturated, C12-15 alcohol (linear and branched), esters to terrestrial organisms.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
