Applicant's summary and conclusion
- Conclusions:
- The test item has no melting point. At ca. 250°C, the test item started to decompose.
- Executive summary:
The melting point of acylglycinate GCS-11 -T was investigated in a study conducted according to EU Method A.1 (Melting / Freezing Temperature) and OECD Guideline 102 (Melting point / Melting Range). The endothermic signals observed in the DSC-runs could not be assigned clearly to the melting and boiling point of the test item. Therefore additional measurements were performed using the capillary method. Based on the capillary measurements the test substance has no melting point under atmospheric pressure. The test item showed a stepwise transformation of its aggregation state. At ca. 250°C, the test item started to decompose.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
