Description of key information
The melting / freezing point of Isopentyl p-methoxycinnamate was 3.5 °C at 100.9 kPa.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 3.5 °C
Additional information
The melting / freezing point of the test substance was determined according to EU method A1. Using this method the melting point of the test substance was determined to be 3.5 °C at atmospheric pressure.
Result of the screening test:
The sample stored at 4°C remained unfrozen after 24 h of storage, while the two samples stored at -20°C and -80°C were found to be frozen.
Results of the accurate test:
"Test 1 initial":
The temperature was slowly lowered to -9.5°C over a period of approximately 40 min and the temperature of the test substance was measured every 30 s from 3.5°C onwards, at which point the sample was very viscous but not solid and further temperature change was not observed.
"Test 1 repeat":
The temperature profile was the same as for "Test 1 initial" but was run over a longer period of approximately 60 min. When the temperature had reached -9.5°C, a seed crystal from an aliquot of sample frozen at -80°C was added to the test solution. The test solution immediately solidified, the temperature immediately dropped to -10.5°C and then rose over a period of 2 min to a steady state temperature of 3.5°C for approximately 5 min before the temperature decreased again. The test solution remained solidified during the increase in temperature from -10°C to 3.5°C.
"Test 2":
This test was performed like "Test 1 repeat" but with the temperature of the test substance being measured every 30 s from 3°C onwards. The temperature slowly lowered to -9.5°C over a period of approximately 77 min. Once the temperature had reached -9.5°C, a seed crystal from an aliquot of sample frozen at -80°C was added to the test sample. The test solution immediately solidified and the temperature immediately dropped to -10.5°C and then rose over a period of 3 min to a steady state temperature of 3.5°C for approximately 7 min before the temperature decreased again. The test solution remained solidified during the increase in temperature from -10°C to 3.5°C.
From the results of the 3 experiments it was concluded that the melting / freezing point of test substance is 3.5°C.
This value corresponds to the average of the first 5 consecutive readings, during which the temperature of the solidified test solution remained constant within ±0.5°C.
