Additional information

No chronic invertebrate studies on toxic effects of AES (C9 -11, 1 -2.5EO) NH4 (CAS 160901 -27 -9) are available. Therefore, this endpoint is covered by read across to a structurally related AES (C8 -10, 2.5EO) NH4 (CAS 68891 -29 -2).

Examining the toxic effects of AES (C8 -10, 2.5EO) NH4 a GLP study was performed according to OECD guideline 211 (BASF, 2013). Under semi-static conditions a NOEC (21 d) of 5.3 mg a.i./L (measured) for Daphnia magna was observed. The NOEC value was based on reproduction.
