Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 a Weight of Evidence approach, it can be possible to consider that Eucalyptus oil is readily biodegradable. All major constituents are readily biodegradable.

Key value for chemical safety assessment

Biodegradation in water:: readily biodegradable

Additional information

All major constituents of Eucalyptus oil are considered readily biodegradable (see table below).
