Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2018-03-29
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Version / remarks:
- 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- 2008
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- signed 2017-02-28
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- Storage conditions: Ambient temperature, closed container and dry
- Boiling pt.:
- > 600 °C
- Atm. press.:
- 995 hPa
- Remarks on result:
- other: no boiling point up to 600 °C
- Conclusions:
- The DSC graphic show an endothermic effect beginning at 370 °C with a mass loss of approx. 78 % of the test substance. However, this effect is not assigned to a melting or boiling of the test itembut may be a decomposition/transformation. Hence, no definitive signs of melting/boiling of the test substance was observed by differential scanning calorimetry (DSC) measurement up to 600 °C. The measurement was performed in accordance with Regulation EC No. 440/2008 Method A.1/A.2. and OECD Test Guideline 102/103 (1995) at atmospheric pressure (995 hPa).
Reference
Melting/boiling point (DSC)
In both DSC runs one endothermic effect was observed in the temperature range from 370 °C through 530 °C. In both DSC runs no further endothermic or exothermic effect was detected.

No definitive signs of melting/boiling of the test substance were observed up to 600 °C.
The DSC graphic showe an endothermic effect beginning at 370 °C with a mass loss of approx. 78 %. Effects may be a decomposition/transformation.
Description of key information
No definitive signs of melting/boiling of fatty acids, C6-19-branched, calcium salts was observed by DSC measurement up to 600 °C.
Key value for chemical safety assessment
Additional information
The DSC graphic show an endothermic effect beginning at 370 °C with a mass loss of approx. 78 % of the test substance. However, this effect is not assigned to a melting or boiling of the test itembut may be a decomposition/transformation. Hence, no definitive signs of melting/boiling of the test substance was observed by differential scanning calorimetry (DSC) measurement up to 600 °C. The measurement was performed in accordance with Regulation EC No. 440/2008 Method A.1/A.2. and OECD Test Guideline 102/103 (1995) at atmospheric pressure (995 hPa).
