Description of key information

The freezing temperature of the test item has been determined to be less than -50 °C (<223.15 K), using a procedure designed to be compatible with Method A1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-50 °C

Additional information

For the purposes of environmental exposure assessment, the melting point is required for solids to estimate sub-cooled liquid vapour pressure. Given that no freezing was observed for the UVCB substance to a temperature of -50°C, it is assumed that all components of the UVCB would be in a liquid form in the environment. Hence the value of -50°C has been assigned to the two assignment entities being used for environmental exposure and risk assessment.
