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 OS9600 (48h-EC50 > 100 mg/L and the 48h-NOEC >= 100 mg/L), the 48h-EC50 for OS9600 was determined to be >134 mg/L and the 48h-NOEC >= 134 mg/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
