EC number: 500-464-9
CAS number: 160901-27-9
1 - 2.5 moles ethoxylated
Readily biodegradable: 100% (inorg. C) in 28 days (ISO 14593)
Comparing all available readily biodegradation studies, the members of
the AES category are generally to be found readily biodegradable (HERA
 & Danish EPA ).
Since no biodegradability tests are available for AES (C9 -11, 1-2.5EO)
NH4 (CAS 160901-27-9), a read-across approach from the structural
comparable AES (C9-11, 1-2.5EO) Na (CAS 160901-28-0) was applied.
This none-GLP study was performed with domestic sludge according to ISO
Guideline 14593 (Huntsman, 2006). Based on inorganic C analysis a
biodegradation rate of 100% was reported after 28 days.
Therefore, AES (C9 -11, 1 -2.5EO) NH4 (CAS 160901-27-9) is considered to
be readily biodegradable.
