Any other information on results incl. tables
Since no detectable signal of the Ciclopirox-EDTA-TB (III) complex were found in the sorbent extracts using a specific HPLC/FLD method, a vapour pressure value was calculated from LOQ level standard concentration (i.e. 0.6 µg/ml) and the vapour pressure value of Ciclopirox olamine referred as lower than this results.
Applicant's summary and conclusion
- Conclusions:
- Vapor pressure of Ciclopirox olamine is lower than 0.00014 Pa at 20°C.
