Conclusions:
The Freezing point of test chemical was determined using Freezing Temperature Method. No freezing was observed up to -14.83 °C.
Executive summary:

The Freezing point determination of test chemical was done using Freezing Temperature Method (crushed ice and salt). No freezing was observed up to -14.83°C. Hence, the freezing point was inferred to be less than -14.83°C at 971.1 hPa.

Description of key information

The Freezing point determination of test chemical was done using Freezing Temperature Method (crushed ice and salt). No freezing was observed up to -14.83°C. Hence, the freezing point was inferred to be less than -14.83°C at 971.1 hPa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-14.83 °C

Additional information

The Freezing point determination of test chemical was done using Freezing Temperature Method (crushed ice and salt). No freezing was observed up to -14.83°C. Hence, the freezing point was inferred to be less than -14.83°C at 971.1 hPa.
