Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The vapour pressure of the test substance has been determined to 0.73 mPa at 20°C and 1.2 mPa at 25°C, using data from a similar substance in a category approach.

Key value for chemical safety assessment

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

Additional information

Read across. 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.
