Description of key information

EC50 (48 h) for Daphnia magna = 91 mg a.i./L (nominal, DIN 38412, part II) 

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
91 mg/L

Additional information

No acute invertebrates studies on toxic effects of AES (C10 -12, 1 -2.5EO) Na (CAS 68610 -66 -2) are available. Therefore, a read-across approach from the structural comparable AES (C8 -10, 2.5EO) Na was applied.

This study was performed according to DIN 38412, part II for AES (C8 -10, 1 -2.5EO) Na. Under static conditions an EC50 (48 h) value of 91 mg a.i./L (nominal) for Daphnia magna was determined (Z&S, 1992).
