Results and discussion
Melting / freezing point
- Decomposition:
- yes
- Remarks on result:
- other: Pressure was not indicated in the report
Any other information on results incl. tables
For both assays, at the beginning of the test, a green powder was weighed into the crucible and after the heating procedure, it remained a dark brownish powder. Three endothermic peaks were observed during the heating phase but were not considered to be melting phases. They were probably due to successive decompositions of the formulation.
Applicant's summary and conclusion
- Conclusions:
- After the heating procedure, no melting point was determined, a decomposition was observed.
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.
