Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Based on read across Alkenes C10-C13 are considered to be readily biodegradable.

Key value for chemical safety assessment

Additional information

Turner and Watkinson (1985) conducted a closed bottle ready biodegradation screening study with alkenes C10/11/12/13. After 28 days 60 -67 biodegradation was observed, indicating that the test substance is readily biodegradable. The same study reports results from a Modified Sturm test which showed 32 -43% biodegradation over 28 days.

These results allow us to conclude that alkenes C10-13 are readily biodegradable.
