Conclusions:

The freezing temperature of the substance has been determined to be less than 253 ± 0.5 K or < -20 ± 0.5 °C.

Executive summary:

The melting/freezing temperature was determined using EU Method A.1 and OECD Method 102 - crystallisation point / freezing temperature method under GLP. The test substance remained unchanged in appearance during cooling. The mean freezing temperature of the test substance has been determined to be less than 253 ± 0.5 K or < -20 ± 0.5 °C at 1 atmospheric pressure.
