Description of key information
Two ready biodegradation studies (OECD 301D) were conducted with two different batches of the substance.
Batch I23-090312 : 83% biodegradation after 28 days
Batch 129958 : 81% biodegradation after 28 days
The substance is readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Experimental studies were performed on two different batches of the substance in order to address the biodegradability according to OECD TG No. 301D and GLP. The test material was tested at concentrations of 2 mg/L and the inoculum was river water. The degradation of the test material was assessed by the determination of the oxygen consumption.
After 28 days, the biodegradation percentage was 83% for batch I23 -090312 and 81% for batch 129958 based on O2 consumption.The 14-day time window criterion was met in both studies. Thus, the substance is considered as readily biodegradable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
