Applicant's summary and conclusion
- Conclusions:
- No freezing of the test substance was observed down to a temperature of -50.0°C (223.15 K)
Therefore:
Freezing point of Dihydro Ionone Alpha < -50.0°C (< 223.15 K). - Executive summary:
The freezing point of Dihydro Ionone Alpha 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 Dihydro Ionone Alpha < -50.0°C (< 223.15 K).
