Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2013-03-22 to 2013-03-25
- 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 102 (Melting point / Melting Range)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- signed, 2011-04-11
- Type of method:
- method to determine freezing temperature
- Key result
- Melting / freezing pt.:
- < -80 °C
- Conclusions:
- A melting point or melting range of the test item VP 112/18 could not be determined, as the test item is not completely solidified at – 80 °C and no main study was carried out. Therefore, the melting point is stated as < – 80 °C (< 193.15 K).
According to Regulation (EC) No 1907/2006, Annex VII, Section 7.2, Column 2, the determination of the melting point does not need to be conducted below a lower limit of -20 °C.
Reference
Pre Test
No complete solidification was observed at all temperatures; therefore, no main study could be performed
Room Temperature |
5°C |
-20°C |
-80°C |
Viscous and gluey |
More viscous and sticky |
Sticky, high viscous liquid |
Partially crystalline but still sticky |
As the test item was still sticky at -80 °C, the test item was not completely solidified. A melting point or melting range of the test item VP 112/18 could not be determined, as the test item is not completely solidified at – 80 °C and no main study was carried out. Therefore, the melting point is stated as < – 80 °C (< 193.15 K).
According to Regulation (EC) No 1907/2006, Annex VII, Section 7.2, Column 2, the determination of the melting point does not need to be conducted below a lower limit of -20 °C.
No observations were made which might cause doubts on the validity of the study outcome. Therefore, the result of the study is considered valid.
Description of key information
Naphthenic acids, zinc salts, basic has a melting point < - 80 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -80 °C
Additional information
A melting point or melting range of naphthenic acids, zinc salts, basic could not be determined, as it is not completely solidified at – 80 °C and no main study was carried out. Therefore, the melting point is stated as < - 80 °C.
