Additional information

No experimental data are available on the bioaccumulation in organisms.


According to Regulation (EC) 1907/2006 Annex IX, Section 9.3.2, Column 2, the study does not need to be conducted since the substance has a log Kow less or equal than 3. 1,1'-[oxybis(ethyleneoxy)]diethylene (CAS 764-99-8) has a measured log Kow of 1.8 (BASF, 2012, 11L00357, see IUCLID Ch. 4.7). Therefore, and for reasons of animal welfare, an experimental study on bioaccumulation is not provided.
