LC50 (96 h) > 1000 mg/L for Poecilia reticulata (EU Method C.1)

Key value for chemical safety assessment

Additional information

No data are available on the toxicity of (Z)-N-Octadecyldocos-13-enamide (CAS No. 10094-45-8) to fish. Therefore data from the analogue substance N-octadecylstearamide (stearyl stearamide, CAS 13276-08-9) were used as read across. This read-across is in accordance with Regulation (EC) No. 1907/2006 Annex XI, 1.5 and justified in detail in the overall summary (IUCLID Chapter 6.1) and within the analogue justification attached in IUCLID Section 13.

The short-term toxicity of N-octadecylstearamide (stearyl stearamide, CAS 13276-08-9) to fish was investigated in a study according to EU Method C.1 and following GLP principles (Balk, 1989). In this limit test, guppies (Poecilia reticulata) were exposed to a nominal concentration of 1000 mg/L under semi-static conditions.
