Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Based on weight of evidence evaluation from two valid studies, both DL-Menthone enantiomers and DL-Isomenthone enantiomers can be considered as readily biodegradable in various mixed compositions (see chapter 4.1.2.1.3 CSR). Therefore the registration item is expected to be rapidly degradable and non-persistent in the aquatic and terrestrial environment. Thus, further testing on biodegradation in water, sediment or soil is not necessary. Information on the abiotic degradation of the substance is not available.
A log Koc value of 2.16 (QSAR estimation) indicate that the substance is highly mobile in soil and sediments according to the classification scheme of McCall et al. (1981).
Furthermore, it is assumed that the substance has a moderate volatility from water surfaces under environmental conditions due to its Henry’s Law constant of 20.2 Pa · m3/mol.
The calculated BCFs of the substance are 47.8 L/kg and 78.1 L/kg, respectively. The B criterion is not fulfilled and thus, the registration item is considered to be not bioaccumulative.
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.
