Conclusions:
Lithium isooctadecanoate was determined to decompose from approximately 185°C (458 K). The test item and/or decomposition products then melted over a range of approximately 193 to 205°C (466 to 478 K), with ongoing decomposition being evident as heating of the test item continued.
Executive summary:

The melting point of lithium isooctadecanoate was determined in a GLP-compliant, differential scanning calorimetry (thermal analysis) and capillary method (visual evaluation) test, following OECD guideline 102 (Envigo 2017). The study is considered relevant and reliable for use for this endpoint.

Description of key information

The melting point of lithium isooctadecanoate is 193-205 °C. Lithium isooctadecanoate begins to decompose at 185 °C.

Key value for chemical safety assessment
