Any other information on results incl. tables
Distearyl N-lauroyl- L- glutamate has been determined to decompose from approximately 320 °C (593 K) at 100.8 to 101.7 kPa, by differential scanning calorimetry, designed to be compatible with Method A2 Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995. As the test item decomposed, no value for boiling temperature could be determined experimentally. A computer prediction gave a boiling temperature of 809 °C (1083 K).
Applicant's summary and conclusion
- Conclusions:
- The test item has been determined to decompose fromapproximately 320 °C (593 K) at 100.8 to 101.7 kPa. As the test item decomposed, no value for boiling temperature could be determined experimentally. A computer prediction gave a boiling temperature of 809 °C (1083 K).
- Executive summary:
Instrument: Mettler Toledo DSC822e Differential Scanning Calorimeter (DSC) incorporating a ThermoHaake Cooler EK45/MT. The temperature accuracy of the DSC was checked prior to testing with indium and zinc. These were within defined tolerances and the DSC was therefore considered acceptable for use.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
