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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Two separate determinations were performed on the supplied EVB. In both cases the thermograms showed no distinct endotherms. The product remained unfrozen at temperatures above - 80°C. The atmospheric pressure at the time of the determinations was 1005.6 hPa The following results were obtained:

Description of key information
The freezing point was less than - 43.5°C when measured using EU Method A.1.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -43.5 °C
Additional information
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.
