Description of key information

Melting/freezing point of the substance is below the lower limit of -20 °C, thus there is no study required.

Key value for chemical safety assessment

Additional information

According to REACh legislation, Annex VII, 7.2, column 2, a study on melting/freezing point does not need to be conducted as the melting/freezing point of the substance is below the lower limit of -20 °C.
