Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Toxicity to terrestrial plants
Administrative data
Link to relevant study record(s)
Description of key information
No experimental data available. Considering all relevant information available, toxicity to terrestrial plants is not expected.
Key value for chemical safety assessment
Additional information
In accordance with Regulation (EC) No. 1907/2006, Annex X, Column 2, 9.4 further studies on the effects on terrestrial plants do not have to be conducted since the chemical safety assessment indicates that there is no need. The terrestrial toxicity of Fatty acids, C8-10, octyl esters has been assessed on the basis of experimental toxicity data for earthworm Eisenia fetida tested with isopropyl myristate (CAS 110-27-0). No mortality was observed during the 14-day exposure period at the test concentration of 20,000 mg/kg.
Additionally, data is available on tests with terrestrial plants for the substance Fatty acids, C16-18 and C18-unsaturated, 2-ethylhexyl esters (CAS 85049-37-2), however it has been assigned with a Klimisch rating of 4 because the full study reports are not available and the information given is not sufficient for evaluation of the study. Nevertheless, this information should be taken into account for the chemical safety assessment (CSA). The tests were conducted according to “EEC Directive 79/831, Annex V; EEC Ring Test C(L1) 3: Higher Plant”. 21-day NOECs, all 100 mg/kg, are reported for the organisms Avena sativa, Lycopersicum esculentum, Brassica rapa. EC50 values of 390 mg/kg, 580 mg/kg and 600 mg/kg are reported for Avena sativa, Lycopersicum esculentum and Raphanus sativus, respectively.
Based on the available data, the terrestrial toxicity of Fatty acids, C8-10, octyl esters is considered to be very low. Additionally, the substances are not expected to remain in the terrestrial environment, due to ready biodegradation. Bioaccumulation is not likely due to rapid metabolism.
In accordance with Regulation (EC) No. 1907/2006, Annex X, Column 2, 9.4 further studies on the effects on terrestrial organisms do not have to be conducted since the chemical safety assessment indicates that toxicity to terrestrial plants is not expected to be of concern.
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.
