EC number: 500-465-4
CAS number: 160901-28-0
1 - 2.5 moles ethoxylated
NOEC (21 d) = 5.3 mg a.i./L (measured) related to reproduction.
No chronic invertebrate studies on toxic effects of AES (C9 -11, 1
-2.5EO) Na (CAS 160901 -28 -0) 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 , 2013a). 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.
