Description of key information

One long-term toxicity test with daphnia has been performed. The 21 d EC10  for reproduction is 160 µg/L and 140 µg/L for parental mortality based on the test substance. The effects are expressed as nominal values because the test was performed with river water as it is intended to be used in an evaluation of the environmental risks based on the Bulk approach. The parental EC50 (21d) was 480 µg/L

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater invertebrates:
140 µg/L

Additional information

Read across for a number of ecotoxicity endpoints is applied from di (2-hydroxyethyl) oleylamine (CAS no 25307 -17 -9) to fill a number of datagaps of di (2 -hydroxypropyl)tallowamine. This is the reason why the robust summary of the long-term daphnia test with di (2 -hydroxyethyl)oleylamine is added to this dossier. A justification for this read-across is included in Chapter 13 of IUCLID.
