Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 range for the tested samples is: 0.0054-2.66 hPa (25 °C)

Key value for chemical safety assessment

Vapour pressure:
0.54 Pa
at the temperature of:
25 °C

Additional information

The vapour pressure of two test samples with somewhat differing compositions was determined according to OECD TG 104 / EU A.4 by the effusion method (vapour pressure balance) and by the dynamic method, respectively. The vapour pressure of one test sample is 0.0054 hPa at 25 °C. The vapour pressure of the other test sample (containing 9.1% water) is 2.66 hPa at 25 °C.

A vapour pressure of 0.54 Pa (25 °C) will be used for risk assessment, as it reflects the properties of the submission substance itself (without water).
