- Executive summary:
A test was performed similarly to OECD 102, Regulation (EC) 440/2008 Method A.1 and EPA OPPTS 830.7200 to determined the freezing point of the test item. In a preliminary test, a sample was cooled down to -20 °C in a cryostat. The test item remained liquid at this temperature, no solidification was detected. Therefore, the freezing point of the test item is <-20 °C.

The test item remained liquid at -20 °C, no solidification was detected.
Description of key information
The test item is liquid at -20 °C.
Key value for chemical safety assessment
Additional information
In accordance with column 2 of REACH Annex VII, the study does not need to be conducted as the melting point of the substance is < -20 °C.
