Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
No effects of the test substance on terrestrial organisms are expected.
Key value for chemical safety assessment
Additional information
No studies on long-term terrestrial toxicity are available for this substance, but due to the properties of the substance a hazard to soil organisms is assumed to be low. In accordance with column 2 of EC 1970/2006 Annex IX the effects of terrestrial organisms need not to be tested if a direct and indirect exposure to the soil compartment is unlikely. Direct exposure to the soil is not reported. Fatty acids, C8-10, Me esters (CAS 85566-26-3) is readily biodegradable and indirect exposure of soil organisms through sludge application can be ruled out. Regarding the low water solubility (0.3 mg/L) it is not likely that the test substances can be found in the aquatic environment in high concentrations and therefore an application due to floods and irrigation can be ruled out and if the substance is exposed to soil, Fatty acid esters are metabolised in Fatty acids and alcohols. These components occur in sediment and soils naturally, are part of physiological pathways and can be used as energy source. The enzyme carboxylesterase is omnipresent in organisms, readily degrading this test substance. Thus, toxic effects caused by the metabolites of fatty acid esters are implausible.
In conclusion, due to a) the lack of chronic exposure and b) the acknowledged metabolisation of fatty acid esters, toxic effects to terrestrial organisms can be excluded.
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.
