Any other information on results incl. tables
The vapour pressure of Triisocetyl Citrate was found to be 0.64 mPa at 20°C and 0.94 mPa at 25°C. The full results are shown in Table 5 (attached) and the Ln VP vs 1/T plot is shown in Figure 23 (attached).
There were no differences between the IR spectra for the untested, control and tested material; the comparative spectra are shown in Figure 24 (attached). Therefore the test substance was unchanged during the test. There is no claim of GLP compliance being made for the IR data due to the fact that full computer validation has not been completed on the instrument.
Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of Triisocetyl Citrate was found to be 0.64 mPa at 20°C and 0.94 mPa at 25°C, under the conditions of the test.
- Executive summary:
In this guideline (OECD 104) study, [conducted with GLP certification], the vapour pressure of the test substance was determined to be 0.64 mPa at 20°C and 0.94 mPa at 25°C.
