Any other information on results incl. tables

First experiment: An endothermic peak between -50°C and 50°C was observed. The extrapolated onset temperature of the endothermic peak was 2.7°C. The peak was most likely caused by melting of the test substance.

Second experiment: Essentially the same results as during the first experiment were observed. The extrapolated onset of the melting peak was 3.2°C.

Applicant's summary and conclusion

Conclusions:
The melting temperature of Aquapel® 203 is 3 ºC.
