Any other information on results incl. tables
Details on observation:
-No exothermic effects were observed from ambient temperature to 410°C
-Endothermic effect was observed between 110 and 150°C (melting)
Applicant's summary and conclusion
- Conclusions:
- Under the conditions of the study thermal decomposition is observed for temperatures above 260°C, no thermal decomposition is observed at tempratures below 150°C.
- Executive summary:
The thermal stability of MEXORYL SAB was studied in compliance with OECD TG 113 using differential scanning calorimetry. The test material and the reference material were heated from ambient temperature to 410°C. No exothermic effects were observed. Endothermic effect was observed between 110 and 150°C, this thermic event being related to melting range of the registered substance. No thermal decomposition was observed at temperatures below 150°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
