Applicant's summary and conclusion
- Conclusions:
- The vapor pressure of the aqueous solution was determined to be 2562.5 Pa at 20°C and 3031.3 Pa at 25°C. A vapor pressure of the solidified material could not be measured due to its high viscosity. An estimation of the vapor pressure for the pure material resulted in a value of 1.39E-005 Pa at 25°C.
- Executive summary:
The test was performed 2000 under GLP according to the Czechian testing method 1.4.2 (similar to method A.4 of Directive 67/548/EEC). The calculation was done in 2011 using the EPI-Suite software v4.10.
