EC number: 500-148-0
CAS number: 61788-89-4
One long-term study conducted with the earthworm Eisenia fetida,
according to the OECD Guideline 222, is available for the subcategory 2
member Fatty acids, C18-unsaturated, dimers (CAS No. 61788-89-4). As no
effects occurred in the this study up to the highest test concentration
of 1000 mg/kg soil dw, the members of the subcategory 2 predominantly
oligomers, are considered as not harmful to terrestrial organisms and no
further testing is needed. It is assumed, that due to the lack of
effects in long-term toxicity tests with soil invertebrates as well as
in a long-term toxicity test with fish within the solubility limit of
the tested substance Fatty acids, C18-unsaturated, dimers, hydrogenated
(CAS 68783-41-5) and a lack of bioaccumulation potential, toxicity to
soil microorganisms cannot be expected. Therefore an additional toxicity
test with soil microorganisms would not be reasonable.
