Description of key information

Column 2 of REACH Annex VII states a vapour pressure ‘...study does not need to be conducted if the melting point is above 300 oC’. EPI Suite (MPBPWIN, v1.43, modified grain method) predicts calcium diformate has a vapour pressure of 3.41 Pa at 25 oC.

Key value for chemical safety assessment

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