Key value for chemical safety assessment

Additional information

In accordance with column 2 of Regulation (EC) No 1907/2006 Annex VIII, IX and X further biotic degradation tests shall be proposed if the result of the Chemical Safety Assessment indicates the need to investigate further the degradation of (Z)-N-octadecyldocos-13-enamide (CAS No. 10094-45-8) and its degradation products. The substance is not readily biodegradable and therefore it could be not excluded that the substance has a potential to persist in the environment if it is exposed to soil. However the release to surface waters, and thereby indirect exposure of soil, is considered as marginally as the substance will be physically removed in sewage treatment plants due to the low water solubility and high adsorption potential. An extensive discharge via a STP effluent is unlikely. Furthermore the substance is assessed to be neither acutely or chronically toxic nor to accumulate in organisms. Thus, it is not expected to pose a risk on soil organisms (long term study is planed). Considering this information, testing for this endpoint is not deemed necessary since the substance is not expected to cause an environmental risk.
