Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusions:
The vapor pressure of the test item determined by the static method was 13.41 hPa at 20ºC and 19.30 hPa at 25 ºC.
Executive summary:

A study to determine the vapor pressure of the test item was conducted according to OECD guideline 104 and EC method A.4 under GLP conditions. The vapour pressure of the test item determined by the static method was 13.41 hPa at 20ºC and 19.30 hPa at 25 ºC.       

Description of key information

Key study: Test method according to OECD 104 and EEC A.4. GLP study. The vapour pressure was 13.42 hPa at 20ºC and 19.30 hPa at 25 ºC.

Key value for chemical safety assessment

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

Additional information

The static method (OECD 104) was conducted as this is the most suitable method for multicomponent liquids.
However, care is needed when interpreting the results since the substance is a complex mixture (UVCB substance); small amounts of volatile components may increase the vapour pressure by several orders of magnitude.
