Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substance Litsea oil (Litsea cubeba) is a Natural Complex Substance (NCS) for which typically 96.6% of the constituents is identified.
Abiotic degradation
Air: The UVCB substance (or each constituent) is not known to contribute to global warming, ozone depletion in the stratosphere, ozone formation in the troposphere or acidification.
Water: Hydrolysis is not expected to be of relevance due to the production method of the substance (steam distillation).
In addition, the UVCB substance is readily biodegradable, hydrolysis has therefore not been further assessed.
Biotic degradation
In a CO2 evolution test (OECD 301B, GLP), it was shown that Litsea
cubeba oil is readily biodegradable (104%, 28d).
Bioaccumulation
The log Kow range for Litsea cubeba oil constituents (calculated using KOWWIN v1.67 QSAR) was found to be 2.06 - 6.3 (16.90% of the constituents has a log Kow >= 4). The potential for bioaccumulation strongly differs between constituents and cannot be concluded for the whole UVCB.
Transport and distribution
For Litsea cubeba, the range of predicted log Koc values is 1.622 to 4.251. This indicates potential for low to strong sorption to soil/sediment, depending on the constituent.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
