Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

NOEC (21 d) = 5.3 mg a.i./L  (measured) related to reproduction.

Key value for chemical safety assessment

Additional information

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.
