Key result
Test no.:
#1
Temp.:
ca. 85 °C
Vapour pressure:
< 0.001 Pa
Remarks on result:
not determinable because of methodological limitations
Remarks:
The vapour pressure of the test item was considered to be lower than 10-3 Pa at 120 °C and as a consequence largely lower than 10-3 Pa at 20 °C. This value of 10-3 Pa corresponds to the minimal limit of pressure determined by the apparatus.

Any other information on results incl. tables

For the assay No. 1, no loss of weight was recorded at 85°C. No degradation of the test item was observed after the experiment; the powder remained beige. The vapour pressure of test item was considered to be lower than 0.001 Pa at 85°C.

For the assay No. 2, a loss of weight was recorded at 120°C. No degradation of the test item was observed after the experiment; the powder remained beige. The vapour pressure of test item was considered to be consequently largely lower than 0.001 Pa at 20°C.

Applicant's summary and conclusion

Conclusions:
The vapour pressure of the test item was considered to be lower than 10-3 Pa at 120 °C and as a consequence largely lower than 10-3 Pa at 20 °C.
Executive summary:

The vapour pressure of the test substance was measured according to OECD 104 / EU A4 guideline using a effusion method weight loss. Two determinations were conducted at 85°C and 120 °C. The vapour pressure of the test item was considered to be lower than 10-3 Pa at 85 °C and as a consequence largely lower than 10-3 Pa at 20 °C.
