Description of key information
Additional information
Dicyandiamide is white, odourless powder. It is, therefore, solid at room temperature with a melting point of 210 degrees C and a relative density of 1.44 g/cm³. It decomposes before boiling. The substance as manufactured has a median particle size of 1.65 µm, with approximately 90% of the mass smaller than 4 µm. The vapour pressure of Dicyandiamide is negligibly low (0.0000085 Pa at 20 °C).
Dicyandiamide is a hydrophilic compound (log Kow -1) and highly soluble in water (32 g/L at 20 °C); as such, the solubility in organic solvents / fat is not considered a relevant property of this substance as it will essentially be insoluble in non-polar solvents. Dicyandiamide is not surface active.
Dicyandiamide is non flammable, and is not susceptible to auto-ignition. It is, as most organic substance are, susceptible to dust explosions when diminuted finely enough, but is not explosive. It is not oxidizing.
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.
