Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Alcohols, C8-10-iso, C9-rich, is readily biodegradable in aerobic freshwater systems with a biodegradation potential of 98%, following standard test guidelines. The registered substance is not expected to persist in the environment under aerobic conditions. This result is consistent with several GLP-compliant studies on similar substances which were also determined to be readily biodegradable; Alcohols, C7-9-iso, C8-rich (OECD 301F), Alcohols, C9-11-iso, C10-rich (OECD 301F), and Isononanol CAS 27458-94-2 (EU method C.4-C).
