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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Estimated <0.001 Pa at 25°C
Key value for chemical safety assessment
Additional information
As the test substance is a mixture of 2 compounds (polycarboxylic acid and alkanolamine) and contains water thus the vapour pressure has been derived from the single compound. The representative compound for polycarboxylic acid is referred to the substance with CAS number 80584-91-4 and the representative compound for alkanolamine is referred to the substance with CAS number 102-71-6.
The vapour pressure values of each compound are as follows:
1) The representative Polycarboxylic acid has been calculated based on Modified Grain Method using recommended MPBPVP (v1.43) module of software EPI Suite and has yielded a value of 9.46 E-13 Pa at 25°C.
2) The representative Alkanolamine has been extrapolated to be 0.000479 Pa at 25°C (Ref. Daubert, T.E., R.P. Danner)
It can be summarized that the vapour pressure of the substance is below 0.001 Pa at 25°C.
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.
