Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In the assessment of lithium neodecanoate, read-across to the assessment entities lithium cations and neodecanoate is applied since the ions of lithium neodecanoate determine its fate and toxicity in the environment.
Regarding the toxic potential of lithium ions to microorganisms, 3-h EC10 and EC50 values of 22.95 and 52.50 mg Li/L were derived in a study with the soluble lithium salt LiOH on respiration inhibition of activated sludge.
Regarding the toxicity of neodecanoic acid, an inhibition of nitrification was not observed at the highest test concentration resulting in a NOEC ≥ 200 mg/L neodecanoic acid.
In sum, lithium neodecanoate seems to have some potential for toxicity to aquatic microorganisms.
Key value for chemical safety assessment
Additional information
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.
