Applicant's summary and conclusion

Conclusions:
No freezing of the test substance was observed down to a temperature of -50.0 °C (223.15K)

Therefore: Freezing point of ISORALDEINE 40 < -50 °C (223.15K).
Executive summary:

The freezing point of ISORALDEINE 40 was measured according to the OECD guideline No. 102 (method of the freezing temperature).

 

No freezing of the test substance was observed down to a temperature of -50.0°C (223.15 K)

 

Therefore:

Freezing point of ISORALDEINE 40 < -50.0°C (< 223.15 K)
