Description of key information

A K1, GLP-compliant study was performed according to OECD guideline 102 and EU Method A.1. Sample was held at -20°C for about 4 hours. No freezing was observed. The freezing point of the test item was therefore determined to be < -20°C (Dekra, 2018).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-20 °C
