Description of key information

The vapour pressure of the test substance has been determined to 0.73 mPa at 20°C, 1.2 mPa at 25°C, and calculated to 0.027 Pa at 60°C.

Key value for chemical safety assessment

Vapour pressure:
0.001 Pa
at the temperature of:
20 °C

Additional information

As a worst case, the vapour pressure is read across from a substance with lower carbon chain distribution within the Primary Fatty Amine Ethoxylated (PFAEO) category. Since the vapour pressure increase with decreasing hydrophobe in a specific homologue, it is a worst case to read across from a substance with lower carbon chain distribution. A value at higher temperature has been estimated using linear regression and the constants obtained from measure data.
