Results and discussion

Melting / freezing point
Key result
Melting / freezing pt.:
-25 °C

Applicant's summary and conclusion

Conclusions:
Freezing point: Less than -25°C
Executive summary:

The study was conducted according to OECD guideline 102, EC method A.1, and EPA/OCSPP 830.7200.


In a trial determination, the test item did not solidify as the temperature was decreased from ambient down to -25°C. No further testing was considered necessary. The freezing temperature of the test item, 15-Crown-5, was determined to be less than -25°C.
