Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- other:
- Justification for type of information:
- Annex VII 7.2 Column 2 states the study does not need to be conducted below a lower limit of - 20 °C.
The Precision Petroleum Labs, Inc. test report and the Sigma-Aldrich SDS support the conclusion that the melting point is less than - 20 °C. - Reason / purpose for cross-reference:
- data waiving: supporting information
- Reason / purpose for cross-reference:
- data waiving: supporting information
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Reason / purpose for cross-reference:
- reference to same study
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- other: ASTM D-97
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- ASTM D97
- GLP compliance:
- no
- Type of method:
- pour point
- Specific details on test material used for the study:
- Product ID: 2-ethyl-2-oxazoline (ETOX from Alvin, TX)
Matrix type: Liquid - Key result
- Melting / freezing pt.:
- < -23 °C
- Atm. press.:
- ca. 1 atm
- Remarks on result:
- other: Reported as Pour Point, < -10 °F
- Conclusions:
- The test material has a pour point of < -23 °C ( < -10 °F).
- Executive summary:
This value agrees with experience during use and handling.
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- secondary literature
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Literature value reported on SDS - no guideline reported.
- GLP compliance:
- not specified
- Type of method:
- other: Not specified
- Melting / freezing pt.:
- -62 °C
- Conclusions:
- The test material has a reported melting point of -62 °C (-80 °F) based on a literature value.
- Executive summary:
This SDS value supports the measured value of pour point < - 23 °C.

Description of key information
The melting point is < -20 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -20 °C
Additional information
The melting point is < -20 °C. This conclusion is supported by the Petroleum Labs, Inc. measured pour point of < -23°C and the Sigma-Aldrich SDS which reports a melting point -62 °C.
The Zedi US Inc. study is disregarded. Values reported disagree with experience during manufacturing and use. Also, the value disagrees with secondary reference values and the subsequent re-testing of the material.
