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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- other: vapour pressure of the corresponding alkanolamine
- Temp.:
- 20 °C
- Vapour pressure:
- 57 hPa

Reference
The experimentally determined vapour pressure of the test item is in the recommended range of 1 to 1000 mbar for differential scanning calorimetry.
Description of key information
Due to the unreliable measurement in the OECD 104 study, the vapour pressure of the corresponding alkanolamine was used as a worse-case assumption. Therefore, the vapour pressure was determined to be 0.00001117 mbar (at 25 °C). Reasoning for the adaptation of data is provided as an attachment in IUCLID chapter 13 (IUCLID data adaptation guidance).
Key value for chemical safety assessment
- Vapour pressure:
- 0.001 Pa
- at the temperature of:
- 25 °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.
