- other:
- Remarks:
- It is assumed that the test was performed under atmospheric pressure.
- Conclusions:
- The freezing point of the test item is <-35.7ºC.
- Executive summary:
The determination of the freezing point of the test item was carried out in accordance with OECD Guideline No. 102 "Melting Point/Melting Range" in conformity with the EEC method A.1, under GLP conditions.
The test item was deposited in a test tube which was placed in an outer tube and set in a Dewar vessel containing the freezing mixture. The test item was stirred and the temperature recorded during cooling. The freezing point of the test item was determined to be <-35.7ºC. Further cooling was not performed.
Reference
It was confirmed that the test item does not achieve the freezing point until -35.7 °C. Further cooling was not performed. The results are shown in Fig 1. The graph was created using Microsoft Excel 2016.
Description of key information
Key study. Method according to OECD 102 and EU A.1, GLP study. The test item has a freezing point <-35.7ºC.
Data waving (study scientifically not necessary / other information available): According to Annex VII column 2 of REACH Regulation, the study does not need to be conducted below a lower limit of -20ºC.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -35.7 °C
