EC number: 931-299-4
CAS number: 68390-94-3
Amides, C16-C18 (even), N,N'-ethylenebis is not readily
biodegradable (5.5% after 28 days, OECD 301B). The substance is not
soluble in water (WS < 0.000005 mg/L) and has a high potential for
adsorption to soil particles as indicated by log Koc values of 7.87 –
8.91 calculated for the main substance components (KOCWIN v2.00). The
available acute and chronic toxicity tests on aquatic toxicity indicated
no toxicity to freshwater organisms.
The substance characteristics indicate that the substance will be
removed in the primary settling tank of fat trap of STPs or by sorption
to sludge solids. Therefore, the release via STP effluent is expected to
be negligible. Volatilisation and subsequent transport through the
atmosphere are unlikely because of the low vapour pressure of the
substance 2.3E-07 hPa (20 °C). The substance data indicate a low
probability of exposure of the soil compartment. If soil organisms are
exposed, it is most likely by surface contact and soil particle
ingestion. In order to cover this potential exposure, a long-term
toxicity test with earthworms according to OECD 222 was conducted (in
accordance with the Guidance on information requirements and chemical
safety assessment, Chapter R.7c, (ECHA, 2017)). The available study
determined no detrimental effects on Eisenia fetida. The reported NOEC
(56 d) was ≥ 1000 mg/kg dry soil.
Based on the substance characteristics and the results of the
available long-term toxicity test, the substance is not considered toxic
to terrestrial organisms.
