Description of key information

The freezing point of the test item has been determined to be less than -20 °C (<253 K).

Key value for chemical safety assessment

Additional information

The determination of melting/freezing point of MEDOL-10 was carried out by the crystallizing point method (Envigo Research Limited, 2018, Study FF28RW). The procedure was designed to be compatible with the EC Method A.1 and the OECD test guideline 102, and was conducted in compliance with GLP.

 

The freezing point of the test item has been determined to be less than -20 °C (<253 K).
