Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- -22 °C
Any other information on results incl. tables
A freezing point for Tea Tree Oil of -22°C was determined (mean of -22°C and -22°C) as indicated by a plateau region in the cooling curve at this temperature (see attached Fig. 1 for a typical cooling curve).
Applicant's summary and conclusion
- Conclusions:
- The freezing point of Tea Tree Oil was found to be -22°C.
- Executive summary:
A GLP-compliant study was carried out to determine the freezing temperature of Tea Tree Oil. The study followed the requirements of EEC method A1, OECD method 102 and OPPTS method 830.7200 without significant deviation. The freezing point of Tea Tree Oil was found to be -22°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
