Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

0.000115 - 0.0152 Pa at 20 °C (SPARC v4.6)
C8/C8: 0.0152 Pa
C8/C10: 0.00133 Pa
C10/C8: 0.00133 Pa
C10/C10: 0.000115 Pa

Key value for chemical safety assessment

Additional information

The vapour pressure of the substance fatty acids, C8-10, C8-10 alkyl esters (CAS 129677-93-6) was determined by QSAR calculation with SPARC v4.6. 4 single constituents were taken into account: C8/C8, C8/C10, C10/C8, and C10/C10.
