Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation in water: screening tests
Administrative data

Description of key information
For 0.84 mg/l of Menthol D Dist a maximum biodegradability of 92% was reached after 14 days of incubation.
For 2.01 mg/l of Menthol D Dist a maximum biodegradability of 76% was reached after 21 days of incubation.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
The biodegradability of D-menthol has been determined in Closed Bottle test (OECD 301D)[i]. The test fulfilled the conditions of validity given by the Guidelines and resulted at 21 days to a mean maximum biodegradability of 76%. Therefore, D-menthol is regarded to be readilty biodegradable. The result is very similar to those obtained on L-menthol following the same protocol[ii]. This reinforces the read-across approach in for all the other parameters.

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.
