Principles of method if other than guideline:

Crystallization and melting of the test item were not observed by experiments on the DSC (differential scanning calorimetry). Therefore an additional test was conducted in which a subsample of the test item was placed overnight in a freezer at -20°C and -80°C. The consistency of the test item was determined after the experiment.

GLP compliance:

yes

Type of method:

method to determine freezing temperature
