Description of key information

Based on the read-across approach from the analogue substance OS1600, the NOEC (28 days) of OS9600 for microorganism toxicity was determined to be 25 mg/L since the test item does not inhibit microbial activity.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
25 mg/L

Additional information

Key study: Read-across approach from experimental data on the analogue substance OS1600: Microbial toxicity was derived from an available ready biodegradation test performed with the analogue substance in accordance with OECD Guideline 301B (GLP study). Based on the read-across approach from the analogue substance OS1600 (NOEC = 21.5 mg/L), the NOEC for OS9600 was determined to be 25 mg/L for microorganism toxicity.
