EC number: 500-464-9
CAS number: 160901-27-9
1 - 2.5 moles ethoxylated
EC10 (16 h) > 10000 mg a.i./L (nominal) for Pseudomonas putida.
For microorganisms, no studies on the toxic effects of AES (C9 -11, 1
-2.5EO) NH4 (CAS 160901 -27-9) are available. Therefore, a read-across
approach from AES (C12 -14, 1 -2.5EO) Na (CAS 68891 -38 -3) and AES (C12
-14, 1 -2.5EO) MIPA (CAS 1187742 -72 -8) was applied as a worst case
Both studies were performed following the procedures of DIN 38412, part
8 under GLP conditions. Based on growth inhibition EC10 values > 10000
mg a.i./L (nominal) for Pseudomonas putida were observed in both tests
after 16 hours (Sasol, 1993, 1999).
