Additional information

Key study: A short-term toxicity test on aquatic invertebrates was performed with OS-2200 according to OECD Guideline 202 under GLP conditions. A limit test was performed with Daphnia magna at 100mg/L of test item. 20 Daphnia magna (<24 h old, 10 per replicate) were exposed to either a control medium or 100 mg/L OS-2200 for 48 hours under static conditions. There was no immobility observed within the period of the test, therefore the 48h-EC50 for OS-2200 was >100 mg/L.
