Description of key information

Based on the components of the multi-constituent substance, the mixture will not evaporate from the water surface into the atmosphere.

Key value for chemical safety assessment

Additional information

Since Tinuvin 292 is a multi-constituent substance consisting of two components a single Henrys Law Constant (HLC) value cannot be defined. Therefore, the HLC was estimated separately for the two components by EPIWIN calculations (bond estimation). For the two substance (CAS 41556-26-7 and CAS 82919-37-7) a HLC of 0.000000776 Pa m³/mol and 0.000488 Pa m³/mol was determined, respectively [BASF SE 2010].
