Applicant's summary and conclusion
- Conclusions:
- The isothermal TGA effusion method was applied for the determination of the vapour pressure of 3,4,5-TRIMETHOXYCINNAMIC ACID.
The vapour pressure of the test item at 20°C (293K) and 25°C (298K) was 1.1E-06 and 2.7E-06 Pa, respectively.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
