1 - 2.5 moles ethoxylated
EC50 (48 h) for Daphnia magna = 91 mg a.i./L (nominal, DIN 38412, part II)
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 acute invertebrate studies on toxic effects of AES (C9 -11, 1
-2.5EO) Na (CAS 160901 -28 -0) are available. Therefore, a read-across
approach from the structural comparable AES (C8 -10, 2.5EO) Na was
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).
