Applicant's summary and conclusion
- Conclusions:
- The DSC shows an endothermic peak which covers a wide range between 39°C and 222°C, with a peak at 139°C.
- Executive summary:
A determination of the thermal stability of the test item by DSC (Differential Scanning Calorimetry) was performed with a DSC Mettler TOLEDO DSC 1, using a perforated crucible.
The DSC shows an endothermic peak which covers a wide range between 39°C and 222°C, with a peak at 139°C. This endothermic peak is considerably broad, over 180°C. It does not seems to be melting point. It might be a relaxation phenomena due to the evaporation of water.
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.
