Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 anions is applied since the ions of lithium neodecanoate determine its fate and toxicity in the environment.
Regarding the toxic potential of lithium ions to aquatic algae and cyanobacteria, 72-h EC10 and EC50 values of 16.92 and > 75.19 mg Li/L were derived for the inhibition of growth rate of D. subspicatus (OECD 201) in a study with the soluble lithium salt (Li2CO3). The toxicity of neodecanoic acid was evaluated, yielding a 72-h EL50 of >100 mg/Lfor the inhibition of growth of P. subcapitata.
Thus, lithium neodecanoate has a low potential for toxicity to aquatic algae and cyanobacteria.
Key value for chemical safety assessment
Additional information
In addition toxicity data are available from studies rated “reliable 3” due to methodological deficiencies. Soluble lithium salts (Li2SO4, LiCl) and elemental lithium were tested resulting in the overall lowest endpoint of 202 mg Li/L (Chlorella vannielii, Scenedesmus spec. and Chlorella vulgaris), further indicating a low toxicity of lithium ions to aquatic algae and cyanobacteria.
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).
