- Executive summary:
The Melting/Freezing Point of Solvent Blue 79B was determined by differential scanning calorimetry, in accordance with Method A.1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 102 of the OECD Guidelines for Testing of Chemicals. The result was 29.19 to 29.94°C

An initial exotherm is observed with an onset of approx. -20°C. This is suspected to be due to glass transition due to the broadness of the peak.
An endotherm is then observed at approx. 30°C which has been attributed to melting.

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.
