1 - 2.5 moles ethoxylated
LC50 (96 h) for Danio rerio = 7.1 mg a.i./L (nominal, OECD 203).
No acute fish studies on toxic effects of AES (C9 -11, 1 -2.5EO)
NH4 (CAS 160901 -27 -9) are available. Therefore, a read-across approach
from a structural comparable AES (C12 -14, 1-2.5EO) mixture was applied
as a worst case scenario.
The study was performed according to OECD guideline 203 in
compliance 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
