Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment

Additional information

The vapour pressure of the substance fatty acids, C8-10 (even numbered), diesters with neopentyl glycol and di- and triesters with trimethylolpropane (CAS 97281-24 -8) was determined by QSAR calculations with SPARC (v4.6) for the single components.
