After investigation by metal block analysis melt onset seen at approximately 30 °C, therefore the melting range is to be given from approximately 25 °C to 50 °C (298 to 323 K).
Conclusion:
The melting point range of the test item has been determined to be approximately 25 to 50 °C (298 to 323 K).
Description of key information
25 to 50 °C (298 to 323 K), by differential scanning calorimetry (Method A.1/OECD 102)
Key value for chemical safety assessment
Additional information
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.
