Description of key information

The Henry constant of DCDPS indicates a very little fugacity from water into the air.

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
at the temperature of:
20 °C

Additional information

The EUSES 2.1.1 estimation is based on molecular weight, the extrapolated experimental vapour pressure (Habeck 2010) and water solubility (Boelhouwers 2004) and indicates a very low fugacity from water into the air.
