Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

QSAR MPBPVP v1.43: 4.17E-6 and 4.42E-5 Pa at 25 and 40°C, respectively.

at the temperature of:
25 °C

Additional information

The QSAR MPBPVP v1.43 has been run on each of 9 identified components of the UVCB. The overall worst-case (highest) vapour pressure has been taken over a total of 27 estimates (9 components x 3 estimation methods).

The most volatile component was component 1: at 25 and 40°C its highest vapour pressure estimates (Mackay method) were 4.17E-6 and 4.42E-5 Pa, respectively. It shows that the substance is of negligible volatility.

As a worst-case, these estimates are used for inhalative exposure assessment for the whole UVCB, i.e. as if the UVCB contained 100% of its most volatile component.
