Key result
Melting / freezing pt.:
< -20 °C
Atm. press.:
1 013.25 hPa
Decomposition:
no
Sublimation:
no
Conclusions:
The freezing point of the test item was determined to be <-20 °C at 1013 hPa.
Executive summary:

A study was conducted according to OECD TG 102, Regulation (EC) No 440/2008 method A.1 and OPPTS 830.7200 to determine the freezing point of the test item. In a pre-test the test item was filled into vessels and stored at 5 °C, -20 °C and -80 °C. The test item was liquid at -20 °C and solid at -80 °C. After storage for one day at -20 °C no change in the physical state was observed. Therefore, in accordance with column 2 of Annex VII of Regulation (EC) No 1907/2006 no main study was conducted. No observations were made which might cause doubts on the validity of the study outcome. Therefore, the result of the study is considered valid. The freezing point was stated as <-20 °C at 1013 hPa.
