Description of key information
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 macroorganisms is regarded to be neglible.
Nevertheless within the alkylethoxylate category terrestrial tests are available which were conducted according to OECD-guidelines. In a test on earthworms conducted with a C16 -C18 alcohol ethoxylate (Cognis, 1990) no acute toxicity of the compound (LC50 > 1000 mg/kg soil dw.) could be demonstrated. In a study conducted with three plant species the NOEC for seedling emergence and growth for all tested plants could be determined to be higher than 100 mg/kg soil dw (Scholz, Sasol, 1994). In conclusion, the risk to terrestrial macroorganisms and terrestrial plants is negliable.
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.
