Reference
The test item shows a melting area of crystalline subcomponents between -37 °C and 12 °C according to the definition in the OECD Guideline 102 (mean value from repeat determination).
-36 °C to 11 °C (from first measurement)
-36 °C to 11 °C (from second measurement)
-39 °C to 14 °C (from third measurement)
At temperatures of about -57 °C the test item shows a glass transition temperature.
The first cooling run shows a crystallization.
The melting area (of crystalline subcomponents) describes a transition in physical form from a hard waxy solid to a soft gel.
Description of key information
A transition in physical form from a hard waxy solid to a soft gel occurs between temperatures of -37 °C and 12 °C (OECD 102, DSC method)
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.
