Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The differential scanning calorimetric experiments were conducted using a Differential Scanning Calorimeter (Model DSC Q20/ RCS 90, TA Instruments, New Castle, DE). Approximately 0.5 mg of the unrefined oil sample was placed in the aluminium sample vessel. The sample vessel was then placed on the sample platform while an empty aluminium vessel was placed on the reference platform. To determine the phase transition of the unrefined oil sample, a linear heating rate of 5°C/min over a temperature range of -90 to 100°C was used. The data collected was plotted and the thermogram peak points were used to determine the melting points.
- GLP compliance:
- not specified
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- Unrefined menhaden fish oil extracted using a rendering process was obtained from a commercial source (Aylesworth‘s Fish&Bait, Inc, St. Petersburg, FL).
- Melting / freezing pt.:
- >= -65.5 - <= 27.2 °C
- Atm. press.:
- ca. 1 atm
- Conclusions:
- The melting points of the unrefined menhaden oil ranged from -69.5 °C to 27.2°C. The DSC thermogram showed endothermic peaks at -36.37 °C, -17.20 °C, -6.32 °C, 1.70 °C and 12.21 °C.
- Executive summary:
This literature report describes a measurement of the melting properties of unrefined menhaden oil by differential scanning calorimetry (DSC). Melting points in a broad temperature range from -69.5 °C to 27.2 °C were reported by the author.

Description of key information
Due to its complex composition menhaden oil changes its state from to liquid over a wide temperature range from ca. -70 °C to ca. 30 °C. Therefore, a melting point in the range of -70 - 30 °C (average -20°C) is considered.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -20 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
