EC number: 406-750-9 | CAS number: 129757-67-1 TINUVIN 123
Henry's Law constant

Description of key information
Key value for chemical safety assessment
Additional information
There are no experimental data on the volatilisation of Tinuvin 123 available. Therefore, the potential to evaporate into the atmosphere from the water surface was estimated using EpiSuites HENRYWIN (v3.20) software.
For compound 1 of Tinuvin 123, a Henry´s Law Constant (@25°C) of 3.50E-006 Pa-m3/mole was predicted. An estimation for compound 2 resulted in a Henry´s Law Constant (@25°C) of 2.25E-016 Pa-m3/mole.
Based on these calculations, Tinuvin 123 isnot expected to evaporate into the atmosphere from the water surface.
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.
