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:
- August 23, 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- other: Stirred test tube
- Key result
- Melting / freezing pt.:
- -2.3 °C
- Atm. press.:
- 101 325 Pa
- Conclusions:
- The freezing point of PPG-2 myristyl ether propionate was concluded to be -2.3 °C at 101325 Pa.
- Executive summary:
The freezing point of PPG-2 myristyl ether propionate was determined in line with OECD Guideline 102 (Melting point / Melting Range) without deviation. A stirred test tube procedure was adopted and as the sample was permitted to cool, the temperature was measured at regular intervals. The temperature fell constant between reading number 14 until 17 and the freezing point of PPG-2 myristyl ether propionate was, therefore, established to be -2.3 °C at 101325 Pa.

Description of key information
PPG-2 myristyl ether propionate has a freezing point of -2.3 °C at 101325 Pa.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -2.3 °C
Additional information
The freezing point was determined according to OECD Guideline 102 (Melting point / Melting Range) without deviation. The final figure is concluded to be a key value for use in chemical safety assessment and has been assigned a reliability score of 1 (reliable without restriction).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
