0 Pa
at the temperature of:
25 °C

Additional information

Vapour pressure of α,α-bis[4-(dimethylamino)phenyl]-4-(phenylamino)naphthalene-1-methanol (Solvent Blue 4) by Modified Grain method was estimated to be 0.00000000000000267Pa at 25 deg C. The value used for the chemical safety assessment is 0.000000001 Pa (due to the input limitations) which indicates that the chemical has very low vapour pressure.
