Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
In accordance with Section 2 of REACH Annex XI, the vapour pressure study (as required in section 7.5) does not need to be conducted as the study is technically not possible. Attempts were made to determine the vapour pressure of the test item using the isoteniscope method. The test item was slowly heated in an isoteniscope tube under vacuum to allow the sample to degas. However, during this process the test item turned to a colourless gel and the test had to be abandoned. This happened on two occasions at temperatures between approximately 70 and 77°C. As the test item cooled it reverted to a clear colourless liquid. It has therefore not been possible to determine the vapour pressure using recommended test guidelines.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
