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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion
Vapour pressure
- Key result
- Remarks on result:
- not determinable
- Remarks:
- At a temperature of appr. 53 °C a continuously descreasing vapor pressure value was recorded. This could indicate a thermally caused change of the test item. Since the test item is a dried compound we assume the recorded pressure values are due to water escaping the test substance during the measurement at declining rates.
Any other information on results incl. tables

Applicant's summary and conclusion
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.
