Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Two studies are available:
1) A biodegradation study (Pence, 1987) is available which is key study. This study showed that the test substance was degraded by more than 60% in 27 days but failed the 10-day window..
2) A biodegradation study (Pence, 1989) is available which is key study. This study showed that the test substance is inherently biodegradable.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

Based on the results of two different biodegradation tests, the test substance can be considered as rapidly and ultimately biodegradable. Although it failed the 10 -day window in the screening test, the test substance degraded almost completely in the SCAS test within 14 days and > 60% in the Modified screening test after 27 days.
