Constituent 1
- Specific details on test material used for the study:
- Test substance was investigated with different water content (up to 40%), results can be obtained up to 60 wt.-% of test item
Results and discussion
Melting / freezing point
- Key result
- Melting / freezing pt.:
- -38 < °C
Any other information on results incl. tables
Substance was tested with different water content. Eutectic point was
between 60 and 100 wt% test item. No crystallization of the test item
was observed due
to very high viscosity. Pure test item (water content ~ 1-2 %) did not
crystallize at – 50 °C, but was highly viscous.
Applicant's summary and conclusion
- Conclusions:
- The freezing point of the test substance is below -38°C
- Executive summary:
The freezing point of the test substance (80 wt%) is below -38°C. Test item containing small amounts of water (water content ~ 1-2 %) did not crystallize at – 50 °C, but was highly viscous and to the blank eye not moving anymore.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
