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

96% of the composition of this NCS is in the category of readily biodegradable substances. Therefore, Mandarin oil is considered to be readily biodegradable.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

Mandarin oil is a Natural Complex Substance (NCS) for which 97% of the constituents is identified. The constituents of Mandarin oil are predominantly alicyclic unsaturated monoterpene hydrocarbons with one or more double bonds. In the typical Mandarin oil, the main constituent limonene is present at 70%, whereas the range is 64 -89%. The assessment of the biodegradability of Mandarin Oil is based on its constituents. The assumption is that if the constituents of the NCS are readily biodegradable, the NCS itself is readily biodegradable as well.

For typically 96% of the constituents the available data are obtained in tests on the ready biodegradability. For 1% of the composition (1 constituent) no results are available but this constituent is expected to be readily biodegradable.

Therefore, Mandarin oil is considered as readily biodegradable.
