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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The mixture is miscible at room temperature.
The experimental data of the individual compounds are as follows:
Polycarboxylic acid: 0.19 mg/L at 20°C at pH 6.5
Alkanolamine: completely miscible
Key value for chemical safety assessment
Additional information
For highly soluble substances a homemade method described in the external method EM/00408/01 from Competence Center Analytics, BASF SE (chapter 4: visual method) was applied to investigate complete miscibility.
The test item is complete miscible with water at room temperature. For mixtures with a ratio <8:2 (test item/water) a slightly turbidity could be observed.
As the test substance is a mixture of 2 compounds (1:3, polycarboxylic acid and alkanolamine) thus the water solubility has been also 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 experimental data of each compound are as follows:
1) Polycarboxylic acid: 0.19 mg/L at 20°C at pH 6.5
2) Alkanolamine: entirely mixable in water at 20°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.
