- Atm. press.:
- ca. 1 013 hPa
- Decomposition:
- yes
- Decomp. temp.:
- > 286 °C
Applicant's summary and conclusion
- Conclusions:
- Alpha-Lipoic acid decomposes at T > 286 °C
- Executive summary:
The boiling temperature from a-Lipoic acid is measured by Differential-Scanning-Calorimetry. The test is according to EG 440/2008 A.2. The exakt boiling point at normal pressure for this substance is not avalible, it decomposes at temeratures T > 286 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
