- Melting / freezing pt.:
- < -29 °C
- Atm. press.:
- 1 013.25 hPa
- Decomposition:
- no
- Sublimation:
- no
- Conclusions:
- Based on the preliminary test, the freezing point of the test item is determined to be below -29 °C.
- Executive summary:
A study was conducted according to OECD TG 102,Regulation (EC) No 440/2008method A.1 and guideline OPPTS 830.7200 to determine the freezing point of the test item. In the test the temperature of the phase transition from the liquid to the solid state was determined. As the test item was not frozen in the course of the preliminary test, the main test was not performed. According to Annex VII, point 7.2, column 2 of Regulation (EC) No. 1907/2006 the study does not need to be conducted below a lower limit of -20 °C. Based on the preliminary test, the freezing point of the test item was determined to be below -29 °C.

Description of key information
Based on the preliminary test, the freezing point of the test item was determined to be below -29 °C.
Key value for chemical safety assessment
Additional information
According to Annex VII, point 7.2, column 2 of Regulation (EC) No. 1907/2006 the study does not need to be conducted below a lower limit of -20 °C.
A supporting study was conducted according to OECD TG 102, Regulation (EC) No 440/2008 method A.1 and guideline OPPTS 830.7200 to determine the freezing point of the test item (references 4.2-2). In the test the temperature of the phase transition from the liquid to the solid state was determined. As the test item was not frozen in the course of the preliminary test, the main test was not performed. Based on the preliminary test, the freezing point of the test item was determined to be below -29 °C.
