Melting / freezing point
Melting / freezing pt.:
< -25 °C

Applicant's summary and conclusion

Conclusions:
In a trial determination, the test substance did not solidify as the temperature was decreased from ambient temperature down to -25°C. No further testing was necessary, as the sample was still liquid at -25°C.
