Results and discussion

Vapour pressure

Vapour pressure 1

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.

Vapour pressure 2

Key result

Test no.:

#2

Temp.:

ca. 20 °C

Vapour pressure:

< 0.001 Pa

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.
