Description of key information

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

Key value for chemical safety assessment

EC10, LC10 or NOEC for microorganisms:
10 000 mg/L

Additional information

For microorganisms no studies on toxic effects AES (C10-12, 1-2.5EO) Na (CAS 68610-66-2) 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.

Both studies were performed following the procedures of DIN 38412, part 8 and GLP. Based on growth inhibition EC10 values > 10000 mg/L for Pseudomonas putida were observed in both tests after 16 hours (Sasol, 1993b, 1999).
