method to determine freezing temperature
Key result
Melting / freezing pt.:
< -20 °C
Decomposition:
no
Sublimation:
no
Remarks on result:
other: The mean of at least two measurements, which are in the range of the estimated accuracy, is reported as the freezing temperature/range.

Comments

The sample was held below -20°C for seven hours. A yellow paste was observed, without crystallization. Therefore no further testing was performed and the result has been reported as < -20°C.

The temperature range of the equipment is -20°C to 150°C

Conclusions:
The freezing point of the test substance was determined to be < -20°C .
Executive summary:

The test is conducted in accordance with the procedure described in EU Regulation (EC) 440/2008, Annex Part A test A.1 and OECD Test Guideline 102.

The freezing point of the test substance was determined to be < -20°C .
