Conclusions:
Under the study conditions, the freezing point of the test substance was determined to be -5°C.
Executive summary:

A study was conducted to determine the freezing point of the test substance, C10-12 and C18-unsatd. DEA, using freezing temperature method, according to the OECD Guideline 102, in compliance with GLP. Under the study conditions, the freezing point of the test substance was determined to be -5°C (Scymaris, 2017).

Description of key information

The freezing point of the test substance was determined using the freezing temperature method, according to OECD Guideline 102 (Scyamris, 2017).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
