other: This study has been performed according to OECD and EC guidelines and according to GLP principles.
Qualifier:
according to guideline
Guideline:
OECD Guideline 104 (Vapour Pressure Curve)

no
Qualifier:
according to guideline
Guideline:
EU Method A.4 (Vapour Pressure)
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Type of method:
effusion method: by loss of weight or by trapping vaporisate
Key result
Temp.:
20 °C
Vapour pressure:
0 Pa
Conclusions:
The isothermal thermogravimetric effusion method was chosen for the determination of the vapour pressure of Decanoic acid, mixed esters with heptanoic acid, octanoic acid and trimethylolpropane.

The vapour pressure of the test substance at 20°C (293K) was 7.55 x 10E-6 Pa = 5.66 x 10E-8 mm Hg.

Description of key information

Determined in accordance with OECD Guideline 104.

Key value for chemical safety assessment

Vapour pressure:
