Description of key information
The vapour pressure of TDI-Urone is negligible.
Key value for chemical safety assessment
Additional information
In accordance with REACH Annex XI, the study does not need to be conducted. Because of the inherent substance structure of TDI-Urone, it can be assumed that the vapour pressure of TDI-Urone can be neglected. This assumption is supported by the value given in the safety data sheet (SDS) from AlzChem Trostberg (2011) and QSAR results:
The vapour pressure as reported in the SDS is < 0.01 bar (< 1000 Pa) at 20 °C.
The Estimation Programs Interface Suite™ for Microsoft® Windows7 of the United States Environmental Protection Agency, Washington, DC, USA, was used to calculate the vapour pressure of TDI-Urone: 7.12E-007 Pa at 25 °C.
