Description of key information

Vapour pressure of Sodium carbonate does not need to be determine as its melting point is above 300 °C.

However, as value it is needed to carry out the risk assessment using the Chesar tool, it is assumed that the VP of sodium carbonate would fall within the lowest default vapour pressure band used by ECETOC TRA (Band D: VP < 0.1 Pa). Therefore, the vapour pressure has been set to 0.09 Pa.

Key value for chemical safety assessment
