Description of key information

Using MPBPWIN the vapour pressure was calculated for the test substance represented by a representative structure and found to be in the range of 1.11.24E-16 Pa at 25 °C.

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
25 °C

Additional information

The vapour pressure of DDNSA is expected to be very low as is confirmed by QSARs with the EPIWIN model for DDNSA and its analogue DNNSA. For the risk assessment on DDNSA the vapour pressure will be set at <1E-08 Pa, which is the cut-off value for determination of fugacity in the ECETOC TRA model.
