Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The vapour pressure of the substance was determined by QSAR calculations with SPARC v4.6, performed for single components. The results of 9.79E-44 - 8.05E-22 Pa at 20 °C for the main constituents reported in section 1.2 indicate that the substance is non-volatile and the overall vapour pressure is estimated as < 0.0001 Pa.
