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 arthropods.

Key value for chemical safety assessment

Additional information

No tests with soil organisms are available for Fatty acids, C18-unsatd., dimers, 2-ethylhexyl esters (CAS No. 68334-05-4), but due to the substance properties and use, a hazard to soil organisms is assumed to be low. Due to its ready biodegradability it is not likely that terrestrial organisms will be exposed to Fatty acids, C18-unsatd., dimers, 2-ethylhexyl esters since it will be ultimately degraded in sewage treatment plants. Furthermore, the substance is not directly applied to soil it is assumed that the substance will not enter the terrestrial environment and as such there is no need for testing of soil organisms (Guidance on information requirements and chemical safety assessment, R7c, pg. 109, ECHA 2012). Furthermore Fatty acids, C18-unsatd., dimers, 2-ethylhexyl esters showed no toxicity in studies with aquatic organisms.

Thus, the generation of soil toxicity data is not required.
