Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
From the water surface, the substance will not evaporate into the atmosphere.
Key value for chemical safety assessment
Additional information
The pKa value of 9.34 (Sparc online calculation, v4.2, 2008) indicates that aziridine will predominantly exist as a cation in the environment, therefore the calculated HLC of 0.74 Pa m3/mol for the uncharged molecule (HenryWin v3.20, 2008) was corrected according to REACH Guidance Document R7a, Appendix R.7.1-2. The pH-corrected HLC (pH 7) for the cation is 0.00336 Pa m3/mol (BASF SE 2010).
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.
