Description of key information
Sodium formate is a white crystalline powder (20 °C, 1013 hPa) with a melting point of 258 °C. It is observed to decompose before boiling from 411 °C. It has a relative density of 1.91. As the melting point was measured to be 200-300 °C, the vapour pressure was calculated to be 1x10-6 Pa at 25 °C using the modified Grain method as implemented in the EPISuite MPBPWIN v1.43 model. The log10 partition coefficient of formic acid, a structural analogue, at 23 °C was measured to be -1.9 (pH 5); -2.1 (pH 7); -2.3 (pH 9).
Sodium formate is completely soluble in water at 20 °C (> 1000 g/L), has a dissociation constant of 3.86 at 20 °C and a 1 g/L aqueous solution has a surface tension of 71 mN/m at 20 °C. No self-ignition was observed below 400 °C. Sodium formate is not classified under any physical hazard CLP endpoint. Flash point, stability in organic solvents and viscosity are not applicable to the test item.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
