EC number: 500-464-9
CAS number: 160901-27-9
1 - 2.5 moles ethoxylated
NOEC (21 d) = 5.3 mg a.i./L (measured) related to reproduction.
The assessment is based on the data currently available. New
studies, based on the category review and the final decisions issued for
some of the category substances, which are also relevant for this
assessment, are currently being conducted. The hazard assessment with
respect to aquatic toxicity will be updated once all ongoing studies
have been finalised.
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.
