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 negligible.

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 >= 100 mg/kg soil dw (Scholz, Sasol, 1994). In conclusion, the risk to terrestrial macroorganisms and terrestrial plants is negligible.
