Description of key information

Based on the read-across approach from the analogue substance MPKO, the 48h-EC50 of OS3600 in Daphnia magna was determined to be >106 mg/L and the NOEC was >= 106 mg/L based on mobility.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
106 mg/L

Additional information

Key study: Read-across approach from experimental data on the analogue substance MPKO:

A short-term toxicity tests on aquatic invertebrates was performed according to OECD Guideline 202 in Daphnia magna (GLP study). Based on the read-across approach from the experimental data on the analogue MPKO, the hydrolysis product of OS3600 (48h-EC50 > 100 mg/L and the 48h-NOEC >= 100 mg/L), the 48h-EC50 for OS3600 was determined to be >106 mg/L and the 48h-NOEC >= 106 mg/L.
