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.
