Key value for chemical safety assessment

Additional information

Data waiving according to EC 1907/2006 Annex IX. The test substance was found to be poorly biodegradable in water. Hence, it is assumed that the results of simulation studies would not reveal any different findings. Therefore, simulation studies on surface water and sediments are not provided.

Study technically not feasible due to the very low water solubility. Furthermore, the substance is very stable and heteroagglomeration/aggregation with other particles with same material or other particle, e.g. organic matter, or to the interface between phases is very unlikely due to the very low water solubility, low logKow value and non-occurrence of functional groups of the molecule. Aditionally, the substance is not expected to be adsorptive. Therefore, simulation studies are scientifically not justified.
