Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusions:
The freezing point of ST 02 C 94 was determined to be -12 +/- 0.5 °C.
Executive summary:

Method: The experimental procedure used complied with that specified in EU Method A1.

Procedure: An aliquot of test material was placed into freezing point apparatus, and cooled using a dry ice/acetone bath.

Results: The freezing point of ST 02 C 94 was determined to be -12 +/- 0.5 °C.

Description of key information

Experimental freezing point (i.e. liquid-to-solid transition).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-12 °C

Additional information

An experimental study on freezing point measurement of the test material, was conducted under GLP, and considered as fully reliable. Therefore the result is considered as key data.
