Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

25 °C

Additional information

The key and supporting study were conducted using a procedure according to Method A4 Vapour Pressure of Commission Regulation (EC) 440/2008 of 30 May 2008, Method 104 of the OECD Guidelines for Testing of Chemicals, 23 March 2006 and GLP. No deviations was observed during the tests.

In the key study, a total of ten runs were completed for the main sequence. Equilibrium with regard to vapor pressure was assessed to have been reached over the final four runs. Thus the final four runs have been used to calculate the definitive vapor pressure value for the test item.The vapor pressure of the test item has been determined to be 1.6*10-4 Pa at 25°C

The supporting study gives an approximated value for the vapour pressure : less than 0.017 Pa at 25°C. This value is in accordance with the result of the key study.

The result of the study is more precise, that's why this value is chosen as the vapour pressure of the test item.
