Description of key information

EC10 (16 h) > 10000 mg a.i./L (nominal) for Pseudomonas putida.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
10 000 mg/L

Additional information

For microorganisms no studies on toxic effects AES (C12 -14, 1 -2.5EO) Mg (CAS 160104-51-8) are available. Therefore, a read-across approach from the two structural comparable 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.

Both studies were performed following the procedures of DIN 38412, part 8 and GLP. 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).
