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-Octadec-9-enylhexadecan-1-amide (CAS
No. 16260-09-6) and its degradation products. The substance is only
partly biodegradable in water according to an OECD guideline 301 D and a
repetitive die away test following DGXI/400/84, EEC 1984 (Balk and
Hantink-de Rooij, 1989) but 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
