Materials and methods

Test guideline
according to guideline
other: Protocol for the REACH registration of Natural Complex substances, Appendix 3 Adaptation of the Standard Testing Regime for NCSs.
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.

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)

Results and discussion

Melting / freezing point
Melting / freezing pt.:
< 20 °C

Any other information on results incl. tables

After two days of storage at 5°C., the test substance was a highly viscous liquid.

After two days of storage at -20°C, the test substance was still a highly viscous liquid.

Applicant's summary and conclusion

The test substance has no melting/freezing point above -20°C (253K).
Executive summary:

The test substance has no melting/freezing point above -20°C (253K).
