Description of key information

Because of the substance structure of dicyandiamide, it can be assumed that the vapour pressure of dicyandiamide can be neglected. This assumption is supported by the values given the technical report from Degussa (2002) and the OECD SIDS report (2003).

Key value for chemical safety assessment

Vapour pressure:
0 hPa
at the temperature of:
20 °C

Additional information

There are two data sources available (collection of data and OECD SIDS report) indicating that the vapour pressure is negligible low. The technical report states a value of 0.0000085 hPa at 20°C and the OECD SIDS report states a value of 0.000045 hPa at 100°C.
