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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Surface activity is not a desired property of the material.
Key value for chemical safety assessment
Additional information
A key study reporting a reliable value for TDI-Urone surface tension is not available. However, in accordance with Column 2 adaptation statement of REACH Annex VII, information requirement section 7.6, a key study does not need to be conducted as surface activity is not a desired property of the material.
The online database ChemSpider (http://www.chemspider.com/) reports a calculated value for TDI-Urone surface tension of 49.98 dyne/cm, which is extremely low compared to e.g. water.
(Predicted data is generated using the ACD/Labs’ ACD/PhysChem Suite (http://www.acdlabs.com/products/pc_admet/physchem/physchemsuite/).)
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
