Additional information
No acute fish study on toxic effects of AES (C12 -14, 1-2.5EO) NH4 8CAS 125301 -88 -4)is available. Therefore, a read-across approach from two structural comparable AES (C12 -14, 2.5EO) mixtures was applied.
The first study was performed according to OECD guideline 203 in comliance with GLP requirements. Under flow-through conditions zebra fish (Danio rerio) were exposed to AES (C12-14, 1-2.5EO) Na (CAS 68891-38-3). After 96 h a LC50 of 7.1 mg a.i./L (nominal) was determined (Sasol, 1995).
In the second GLP-study zebra fish (Danio rerio) were exposed to AES (C12-14, 1-2.5EO) MIPA (CAS 1187742 -72 -8) according to OECD guideline 203 (Sasol, 1999). The resulting LC50 (96 h) was 7.7 mg a.i./L (nominal).
