Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The test item comes as solution in water. Any experimental measurement on the test item will be skewed by the water vapour pressure. Of all constituents of this substance, we consider the smallest and thus most volatile molecule, the worst case to be taken into account for chemical safety assessment. This molecule (triethanolamine, CAS #102 -71-6) is seen then as the relevant component for vapour pressure evaluation.
