Materials and methods

Test guideline
Qualifier:
according to guideline
Guideline:
other: Protocol for the REACH registration of Natural Complex substances, Appendix 3 Adaptation of the Standard Testing Regime for NCSs.
Deviations:
no
Principles of method if other than guideline:
Performance of the test:
The test substance was stored for 2 days in a water bath at 5°C. After two days, the test substance was visually inspected
Thereafter, the test substance was stored for 2 days in a freezer at -20°C.

Interpretation:
The state of the test substance is described. If the test substance remains a liquid at -20°C, melting point will also be reported as < -20°C.
GLP compliance:
yes (incl. QA statement)
Type of method:
method to determine freezing temperature
