Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Major constituents of Bergamot oil (limonene, linalool and linalyl acetate, 72%) and related monoterpenes and terpenoid and related esters are known to be readily biodegradable. Thus the NCS itself is readily biodegradable as well.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Bergamot oil is a Natural Complex Substance (NCS) for which 97.4% of the constituents has been identified. The constituents are grouped as predominantly monoterpenoid hydrocarbons with one or more double bonds or related esters (97%). In the typical Bergamot oil, the main constituents are D-limonene, linalyl acetate and Linalool. As no valid empirical results from a test for the ready biodegradation of Bergamot oil are available, the assessment is based on data for its constituents. The assumption is that if the constituents of the NCS are readily biodegradable, the NCS itself is readily biodegradable as well.
For almost all known constituents typically comprising 96.6% of the composition, the available data obtained in tests on the ready biodegradability show that the constituents are readily biodegradable. For some constituents (<1%) the ready biodegradability is decided based on the ready biodegradability of structurally related substances. Thus 97.3% of the composition of this NCS is in the category of ready biodegradable substances and therefore Bergamot oil is considered as readily biodegradable.
With the exception of two constituents (typically present at or below 0.05%), all other known constituents are considered to be readily biodegradable. Based on BIOWIN predictions, these two constituents do not meet the screening criteria for 'Persistent' (PBT-criteria).
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.
