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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
The substance (XDI, an aliphatic diisocyanate) reacts with water. From this reaction, the diamine XDA is formed and CO2. The conversion of XDI to XDA in water is fast. It has been shown, in the environmental studies, that XDA is hydrolytically stable. Based on this information (e. g. half-life XDI less than 12 hours; XDI is not present in the environment), it is considered justified to conclude that the CSA for the environment needs to based on XDA.
The key values for chemical safety assessment are therefore the key values applicable for XDA.
For classification purposes, the results (as expressed in measured concentrations of XDA) have been converted to XDI concentrations (in accordance with the ECHA Guidance on the application of the CLP criteria, 4.1.3.1.1.).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.
