Results
DSC measurement
Two DSC measurements in an aluminium crucible with a hole were performed. The test item was cooled down with a cooling rate of 1 K/min (-50 °C for the first measurement and -80 °C for the second measurement), the minimum temperature was kept for 30 min (first measurement) and 300 min (second measurement) and afterwards the test item was heated up with a heating rate of 10 K/min (maximum temperature 500 °C for the first measurement and 25 °C for the second measurement). The measurements showed no endothermal effect in the temperature range of -80 to 25 °C.
The results of the DSC measurements are summarized in the table 4.2/1 below.

Visual measurements
For clarification a sample each of the test item in a glass vial (approximately 5 ml) was placed into a fridge and a freezer. After 48 h these samples were observed visually (see Table 4.2/2).

State of sample |

Even after 48 h at -23 °C the test item was still mostly in its original state (viscous liquid). Only the viscosity increased at lower temperatures. The test item remained as a viscous liquid at both temperatures.
Due to the results from the DSC-measurements and the visual inspection at lower temperatures, It was concluded that the test item was a liquid with no melting point above -20°C.
Final results
No melting point was measured above -80 °C with DSC method.
However, since melting may be hindered at low temperatures due to supercooling it should only be assumed that no melting point exists above ‑20 °C. This was confirmed by a visual inspection after storage at -23 °C for 48 h.
Description of key information
The test item was a liquid with no melting point above -20°C.
Key value for chemical safety assessment
Additional information
A fully reliable experimental study, conducted according to OECD 102/ EU A1 guideline is available.
It is considered as a key study and the result is retained as key data.
