Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

The biodegradation potential of the substance in water was determined in a screening study according to OECD TG 301C (Modified MITI Test). In this study 100 mg/L test substance was inoculated with activated sludge (adaptation not specified). During the incubation period the biological oxygen demand (BOD) was measured and biodegradation expressed as percentage of the theoretical uptake (ThOD). After 14 days, 80-90% of the substance was biodegraded. The pass level of 60% degradation was reached. Based on these findings, the test substance is classified as readily biodegradable.
