- Principles of method if other than guideline:
- DSC experiments were performed according to the above mentioned guidelines. No melting/freezing point could be determined by DSC. Therefore an additional experiment was performed in which the consistency of the substance was determined by visual observation after storage in freezers at ca. -20°C and at ca. -80°C. The additional experiment is not a guideline study but was described in sufficient detail.
- GLP compliance:
- yes
- Type of method:
- other: 'differential scanning calorimetry' and 'visual observation after storage in freezer'

Any other information on results incl. tables
TGA EXPERIMENT (PRELIMINARY TEST)
Significant decrease of weight from 300°C. 25% weight loss at 414°C and 70% weight loss at 496.5°C.
After the experiment, a black molten residue (original colour: dark brown) remained in the sample container. The change of the colour indicated reaction and/or decomposition of the test item.
DSC EXPERIMENT 1
During cooling no effects were observed. From 225°C an exothermic effect was observed. After the experiment, a black molten residue remained in the sample container and a yellow residue was observed on the lid of the sample container. The change of the colour indicated that the exothermic effect was due to reaction and/or decomposition of the test item.
DSC EXPERIMENT 2
A lower cooling rate of 1°C/minute and a heating rate of 5°C/minute was applied in Experiment 2. The exothermic effect was observed at 200°C. It demonstrated that reaction and/or decomposition of the test item was the reason for the exothermic effect. After the experiment, a black molten residue remained in the sample container.
Applicant's summary and conclusion
- Conclusions:
- The substance has no freezing point at temperatures down to -80°C.
- Executive summary:
Differential Scanning Calorimetry (DSC) experiments were performed in a GLP study according to EC A.1, OECD 102 and OPPTS 830.7200.
DSC experiments showed no effect due to freezing of the liquid substance between 25°C and -90°C.
After storage in freezers, the substance was visually observed to be a viscous liquid at ca. -20°C and a very viscous liquid at ca. -80°C.
Based on all results, it was concluded that the substance has no freezing point at temperatures down to -80°C.
During heating from -90°C to 400°C, reaction and/or decomposition of the substance started at 200°C.
