- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- This study is classified as reliable with restriction by CONCAWE. The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. Therefore, the values presented here are acceptable as they are from a reliable secondary source of phys chem. data

- Remarks on result:
- other: Atmospheric pressure assumed, not stipulated by reference.
- Conclusions:
- The melting/freezing point of petrolatum is 51 to 71°C.
- Executive summary:
The melting/freezing point of petrolatum is 51 to 71oC. This study received a Klimisch score of 2 and is classified as reliable with restriction.
- Endpoint:

- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- This study is classified as reliable with restriction by CONCAWE. The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. Therefore, although the method used is not known, the values presented here are acceptable as they are from a reliable secondary source of phys chem. data
- Principles of method if other than guideline:
- The method did not strictly follow the guideline but is deemed appropriate as utilized in this report.

- 101.3 kPa
- Remarks on result:
- other: Atmospheric pressure assumed, not stipulated in citation.
- Conclusions:
- Melting point values of 36-60°C are representative for petrolatums.
- Executive summary:
Melting point values of 36-60°C are representative for petrolatums. This study received a Klimisch score of 2 and is classified as reliable with restriction.
Referenceopen allclose all
The melting/freezing point of petrolatum is 51 to 71oC.
Reported melting point values of 36-60°C (CONCAWE, 1999, Warth, 1956) are representative for petrolatums.
Melting point values of 36-60°C are representative for petrolatums.
Description of key information
The melting point range for petrolatum is 36 to 71°C.
No melting point of the crystalline component was observed up to 141 dC.
Key value for chemical safety assessment
Additional information
The melting point range for substances in the petrolatum category is 36 to 71°C. A melting point range of 51 to 71°C was reported by CONCAWE (2010a). Additionally, a meting point range of 36 to 60°C was determined by Warth (1956) and CONCAWE (1999a).
No melting of a crystalline main component was observed up to 141 dC.
