Endpoint summary
Administrative data
Description of key information
Short-term toxicity data are available for fish, invertebrates, algae and microorganisms. Long-term toxicity data are available for algae. The lowest short-term toxicity result is 5.62 mg/L for fish. The lowest long-term toxicity result is 3.2 mg/L for algae.
Additional information
Lithium naphthenate consists of lithium salts of naphthenic acid. Therefore, data have been presented for both the organic anion and the lithium cation. Studies are included for naphthenic acids as well as lithium salts of docosanoic acid (C22) and dilithium adipate (C6).
Taking a worst-case approach for the results of the key studies, the short-term toxicity (96 hour LC50) of lithium naphthenate to fish is determined to be 5.62 mg/L. The short-term toxicity (48 hour EC50) of lithium naphthenate to invertebrates is determined to be 20 mg/L. The toxicity of lithium naphthenate to algal growth is determined to give a 72 hour EC50 of 23 mg/L and a 72 hour NOEC of 3.2 mg/L.
The toxicity to microorganisms endpoint has been waived on the basis that lithium naphthenate is not soluble in water.
It should be noted that, the reactions to form lithium naphthenate occur in situ during the grease manufacturing process and consequently these grease thickeners normally only exist in the base oil matrix. In realistic use scenarios, the thickeners will be contained in base oil, with the formulated greases specifically designed to minimise the leaching of the thickener. The thickeners would not be bioavailable and therefore, toxicity to aquatic micro-organisms is not considered to be relevant.
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.
