Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 19.10.-20.10.2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no

- Key result
- Atm. press.:
- 98 kPa
- Decomposition:
- yes
- Decomp. temp.:
- >= 230 °C
- Conclusions:
- The water evaporation connected with the beginnig thermal decomposition was observed between start temperature and 190 °C. The rapid thermal decomposition of the test substance started at the temperature 230 °C. Any peaks correspond to the melting or boiling of the test substance was not observed to the temperature at whitch the thermal decomposition started.
- Executive summary:
The melting of the testsubstance, Acid Yellow 25 was investigated. The Differential Scanning Calorimetry method was used.
The procedures used in the study were in accordance with:
- Method A.1. Melting/Freezing temperature,Council Regulation (EC) No.440/2008, Published in O.J. L 142, 2008
- OECD Test Guideline No.102, Melting Point/Melting Range, Adopted July 27, 1995
The water evaporation connected with the beginnig thermal decomposition was observed between start temperature and 190°C. The rapid thermal decomposition of the test substance started at the temperature 230°C. Any peaks correspond to the melting of the test substance was not observed to the temperature at which the thermal decomposition started.
Melting temperature of the test substance, Acid Yellow 25, could not be determined because of thermal decomposition of the test substance.
