Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 is 0.0000066 hPa at 20°C, 0.000014 hPa at 25°C and 0.00039 hPa at 50°C.

Key value for chemical safety assessment

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

Additional information

Two studies were conducted according to OECD 104.

The key study was conducted according to GLP and the vapor pressure was determined to be 0.0000066 hPa at 20°C.

In the supporting study the vapoure pressure was determined to be 0.0000053 hPa at 20°C.

Thus the vapour pressure from the GLP study of 0.0000066 hPa at 20°C is regarded to be reliable and was chosen as key value.
