Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- adopted on 27 July 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- 2008
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- other: determined by differential scanning calorimetry and visual methods
- Melting / freezing pt.:
- >= -26.9 - <= 9 °C
- Atm. press.:
- 1 015 hPa
- Remarks on result:
- other: pour point: 5 °C ± 3 °C
- Conclusions:
- The melting temperature of the test item was determined by differential scanning calorimetry and visual methods according to the OECD Test Guideline 102 and EU test method A.1:
Melting Range: -26.9 °C - 9.0 °C (1015 hPa)
Pour Point 5 °C ± 3 °C - Executive summary:
The melting temperature of polyglycerin caprylate/caprinate was determined by differential scanning calorimetry and visual methods according to the OECD Test Guideline 102 and EU test method A.1.
No abrupt change of the physical state at a specific temperature was observed, but a continuously increasing viscosity of the sample. The lowest temperature at which movement could be observed was 5 °C ± 3 °C (pour point).
By means of DSC an average melting range of -26.9 °C - 9 °C was measured which is in accordance with the liquefaction measured by visual observation in the melt microscope.

Description of key information
The melting temperature of polyglycerin caprylate/caprinate was determined by differential scanning calorimetry and visual methods according to the OECD Test Guideline 102 and EU test method A.1.
No abrupt change of the physical state at a specific temperature was observed, but a continuously increasing viscosity of the sample. The lowest temperature at which movement could be observed was 5 °C ± 3 °C (pour point).
By means of DSC an average melting range of -26.9 °C - 9 °C was measured which is in accordance with the liquefaction measured by visual observation in the melt microscope.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 5 °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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
