Description of key information
TS-ED 532 is readily biodegradable. The pass level for ready biodegradability (60% of ThOD) was accomplished at the end of the 10-day window. Based on these data, TS-ED 532 is not expected to persist in the environment.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
The ready biodegradability of TS-ED 532 was examined using activated sludge from a municipal wastewater treatment plant. At the end of the 10-day window, covering the period from study day 2 to day 12, the BOD was 68 ± 8% of ThOD for complete oxidation of the TS-ED 532. After 28 days, the BOD from degradation of TS-ED 532 corresponded to 98 ± 10% of ThOD. TS-ED 532 was found to be readily biodegradable fulfilling the 60% pass level and the 10-day window requirement. Based on these data, TS-ED 532 is not expected to persist in the environment.
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.
