Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
LC50 (14d) > 1000 mg/kg soil dw for mortality of Eisenia fetida
NOEC (19d) >= 100 mg/kg soil dw. for seedling emergence and growth of Lepidum sativum, Brassica alba and Triticum aestivum
Additional information
Generally, the substance is not supposed to be directly applied to soil and further is readily biodegradable. Hence in case of indirect exposure to soil, the substance is expected to rapidly degrade. Therefore soil is not expected to be a compartment of concern. Thus the risk to terrestrial organisms is regarded to be negligible.
Nevertheless within the alkylethoxylate category terrestrial tests are available. This includes acute toxicity tests on earthworm (BASF, 1990) and on plant seedling emergence and growth (Sasol, 1994). Based on the results of these studies, it can be concluded that alcohol ethoxylate have a low impact on terrestrial macroorganisms and terrestrial plants. For more detail see endpoint summary for soil macroorganisms and plants.
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.
