Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

There are no data available for lithium isooctadecanoate but data have been read across from freshwater ecotoxicity studies on lithium 12-hydroxystearate (Harlan 2013) which showed no effects at up to 100 mg/L loading rate. Lithium isooctadecanoate and lithium 12 -hydroxystearate are both lithium salts of C18 monocarboxylic acids, with lithium isooctadecanoate having a methyl branch on the carbon chain and lithium 12-hydroxystearate having a hydroxyl group on the carbon chain (see IUCLID section 13 for read across justification).

Additional testing is currently ongoing for toxicity of lithium isooctadecanoate to algal growth and, as lithium isooctadecanoate is poorly soluble, a testing proposal has been submitted for long-term toxicity to Daphnia.

  

PNECs have not been derived for freshwater, marine or intermittent release as the read across substance was tested as a water accommodated fraction. Based on read across, lithium isooctadecanoate showed no aquatic toxicity at the limit of solubility. Lithium isooctadecanoate has a vapour pressure of less than 10 E-10 Pa, has a low potential for bioaccumulation or adsorption, is readily biodegradable and is not applied directly to soil. Therefore, the STP, sediment, soil, secondary poisoning and air PNECs were not derived for lithium isooctadecanoate.

Conclusion on classification

There are no data available for lithium isooctadecanoate, though an algal growth inhibition study is currently ongoing and a long-term toxicity study on aquatic invertebrates has been proposed. The environmental classification will be updated, if required, once the additional data are available.

 

Studies for short term toxicity have been read across from lithium 12-hydroxystearate (Harlan 2013), which showed no effects at up to 100 mg/L loading rate. Therefore, lithium isooctadecanoate does not meet the criteria for classification as acutely toxic to the aquatic environment under the EU CLP.

 

Chronic aquatic toxicity data have been read across from lithium 12-hydroxystearate, which showed no effects for algae at up to 100 mg/L loading rate, and lithium isooctadecanoate is considered to be readily biodegradable, with a low potential for bioaccumulation. As such, lithium isooctadecanoate does not meet the criteria for chronic toxicity to aquatic organisms.
