Results and discussion

Melting / freezing point
Melting / freezing pt.:
< -50 °C

Applicant's summary and conclusion

Conclusions:
No freezing was observed down to a temperature of -50.0 ºC (223.15K)
Therefore: Freezing point of Neocaspirene Stage 1 <-50.0 ºC (223.15K)
Executive summary:

The freezing point of Neocaspirene Stage 1 was measured according to the OECD Guideline No. 102/EU Method A.1/EPA OPPTS 830.7200 (method of the freezing temperature).

No freezing was observed down to a temperature of -50.0 ºC (223.15K)

Therefore: Freezing point <-50.0 ºC (223.15K)
