Applicant's summary and conclusion

Conclusions:
The melting/freezing point of hydroxycitronellol was determined to be <-100°C at atmospheric pressure ranging from 991 to 997.6 hPa.
Executive summary:

The melting point of hydroxycitronellol was investigated in a study conducted according to OECD Guideline 102 (Melting point / Melting Range; 1995), EU Method A.1 (Melting / Freezing Temperature; 2008), and EPA OPPTS 830.7200 (Melting Point / Melting Range; 1998) using Differential Scanning Calorimetry. Based on the results of the DSC measurements, the test substance has no freezing or melting point, respectively, down to -100°C at atmospheric pressure ranging from 991 to 997.6 hPa.
