Description of key information

Thise endpoint can be waived because the substance does not melt under 240°C and starts to decompose at 295°C, so the vapour pressure will be low.

Key value for chemical safety assessment

Additional information

Based on its multiple carboxylic acid salt functionality the pure substance will have a negligibly low vapor pressure. Because of its high polarity the substance always contains a few % of water so the vapour pressure exhibited by this substance is expected to be that of the adherent water.

The low vapour pressure is supported by EPI Suite: the vapour pressure of EDTA-CaNa2 is calculated to be 4.10E-17Pa at 25°C.
