Results and discussion

Melting / freezing point

Melting / freezing pt.:

4.8 - 13.2 °C

Any other information on results incl. tables

The mean of at least two measurements, which are in the range of the estimated accuracy, is reported as the freezing temperature/range. The temperature range of the equipment is -20 °C to 150 °C.

Run Number	1	2
Mass of sample used (g)	5	5.3
Initial Freezing Temp (°C)	13.2	12.9
Final Freezing Temp (°C)	5.7	4.8

Result : 4.8 – 13.2 °C

Due to the viscous nature of the test material, it was extremely difficult to stir the sample.

Applicant's summary and conclusion

Conclusions:

The test compound was found to have a freezing point of between 4.8 and 13.2 °C.

Executive summary:

In a freezing point determination study (GLP105148AR1V1/10), the freezing point of the test material was determined to be between 4.8 and 13.2 °C, according to EU test method A.1.
