Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

The freezing point of Citrathal Concentrate S TW was determined to be <-50.0°C (223.15 K)
Executive summary:

The freezing point of Citrathal Concentrate S TW was determined according to the OECD guideline No. 102 (method of the freezing temperature).

The freezing point of Citrathal Concentrate S TW was determined to be <-50.0°C (223.15K)

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.
