Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The test item did not change in appearance under the conditions used in the determination. The results may represent rounded-off values obtained by calculations based on the exact raw data.

Conclusions:
The vapour pressure of lithium salts of fatty acids predominantly C24 – C28 (saturated) has been determined to be 3.9 x 10(-8) Pa at 25°C.
Executive summary:

The vapour pressure of lithium salts of fatty acids predominantly C24 – C28 (saturated) was determined in a GLP-compliant, analysis study (Envigo 2017) following OECD guideline 104 and EU method A.4. The study is considered relevant and reliable for use for this endpoint.

The vapour pressure of lithium salts of fatty acids predominantly C24 – C28 (saturated) has been determined to be 3.9 x 10 -8 Pa at 25°C.

Description of key information
