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.
