Results and discussion

Melting / freezing point
Melting / freezing pt.:
< 253 K
Remarks on result:
other: less than 253 +/- 0.5 K equals -20 +/- 0.5 °C

Any other information on results incl. tables

No change in test material appearance on cooling.

Results from measurements in °C and conversion into K using the following equation: T = t + 273.15

(T = temperature in K; t = temperature in °C)

Applicant's summary and conclusion

Conclusions:
The determined melting point/freezing point is < -20 °C. According to REACH Regulation (EC) No 1907/2006, Annex VII, 7.2. Melting/freezing point, the study does not need to be conducted below a lower limit of - 20 °C.
