Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information

The available data from freshwater ecotoxicity studies on fish, Daphnia and algae with lithium myristate, lithium 12-hydroxystearate and lithium myristate (Harlan 2013) showed no effects at up to 100 mg/L loading rate.

Testing is ongoing for algal growth inhibition of fatty acids C16 -18 (even numbered) saturated and C16 -20 (even numbered) unsaturated lithium salts. Testing proposals are submitted for long-term toxicity toDaphniaand fish for lithium 12 -hydroxystearate, lithium myristate, lithium docosanoate and fatty acids C16 -18 (even numbered) saturated and C16 -20 (even numbered) unsaturated lithium salts. The results of these studies will be read across to other category members and the PNEC will be updated as appropriate.

The substances show no toxicity at their limit of solubility, have vapour pressures of less than 10 E-10 Pa and a low potential for bioaccumulation or adsorption, and are readily biodegradable and not applied directly to soil. Therefore, the STP, sediment, soil, secondary poisoning and air PNECs were not derived due to a lack of potential exposure or a lack of identified hazard.

Conclusion on classification

None of the substances in the lithium salts of monocarboxylic acids C14-C22 category showed acute toxicity to aquatic organisms at up to 100 mg/L WAF and therefore they do not meet the criteria for classification as acutely toxic to the aquatic environment under the CLP.

 

No effects were seen in the 72-hour algal growth studies (NOELR >100 mg/L) for lithium myristate, lithium 12-hydroxystearate and lithium behenate, which have been read across to the remaining substances in the category.

No ecotoxicity effects on aquatic species were observed at up to the limit of solubility (based on a loading rate of 100 mg/L) in any of the studies to date on substances in the lithium salts of monocarboxylic acids C14-C22. The substances in the category are readily biodegradable and have a low potential for bioaccumulation (8 L/kg based on lithium). As such, the substances are considered not meet the criteria for classification as chronically toxic to the aquatic environment under the CLP.

Testing proposals are submitted for long-term toxicity to Daphnia and fish for lithium 12 -hydroxystearate, lithium myristate, lithium docosanoate and fatty acids C16 -18 (even numbered) saturated and C16 -20 (even numbered) unsaturated lithium salts. The results of these studies will be read across to other category members and the classification will be updated as appropriate.
