Any other information on results incl. tables
The effects observed are related to evaporation of the test substance.
The substance is concluded to be stable at room temperature.
Applicant's summary and conclusion
- Conclusions:
- The test substance is stable at room temperature
- Executive summary:
In two experiments the test substance was shown to be stable at room temperature. The thermal stability assessed with TG-DTA apparatus showed no effects at temperatures of 98 °C and below. Effects seen at higher temperatures were attributed to evaporation.
