Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Lithium naphthenate consists of many different constituents and the rate of biodegradation can vary between the compounds present in the UVCB. As such, QSAR estimates are provided showing the biodegradation potential of representative structures of lithium naphthenate. The QSAR estimates show that most representative structures are readily biodegradable, though some are predicted as not readily biodegradable, and none of the prediction results for the structures meet the screening criteria for P or vP in the PBT assessment.
Lithium naphthenate consists of a lithium cation and a naphthenic acid component. As the lithium cation is inorganic, it has not been considered further for biodegradation and the data presented for the endpoint relate to the organic component. Experimental data are provided (Clemente et al (2004) and Herman et al (1993 and 1994)) which show that naphthenic acids can be degraded by adapted organisms. Experimental data are provided (Harlan (2013), Gerike and Fischer (1979) and Kim et al (2001)) which show that structural analogues for constituents in lithium naphthenate are readily biodegradable.
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.
