EC number: 500-464-9
CAS number: 160901-27-9
1 - 2.5 moles ethoxylated
NOEC (56 d) = 750 mg a.i./kg soil dw for Eisenia fetida
Since no studies on toxicity to soil organisms are available for
AES (C9-11, 1-2.5EO) NH4 (CAS 160901 -27 -9) a read-across approach from
a AES (C12 -14, 2EO) Na (CAS 68891 -38-3) was applied as a worst case
In this test individuals of Eisenia fetida was exposed to
different test concentrations of AES (C12 -14, 2EO) Na (CAS 68891-38-3).
The study was performed according to OECD Guideline 222 under GLP
conditions. The NOEC (56 d) for body weight change and reproduction was
determined as 750 mg a.i./kg soil dry weight. Up to the highest test
concentration (750 mg a.i./kg soil dry weight) no mortality was observed
