- Executive summary:
A study was conducted to determine the vapour pressure of the test substance according to OECD Guideline 104 and EU method A.4. 17.5 and 17.9 mg of the test substance was applied on glass plates respectively, and placed in the thermogravimetric analyzer. The weight loss of the test substance was measured continuously as a function of time from 70°C to 150°C. Benzo(ghi)perylene, chrysene, hexachlorobenzene, naphthalene and water were used as reference substances for validation. The log Vt, 20 value which was obtained by extrapolation of the evaporation rate curve, fitted in the vapour pressure regression curve. From this, it was concluded that the vapour pressure of the test substance at 20°C is 3.28 × 10-2 Pa = 2.46 × 10-4 mm Hg. Under the study conditions, the vapour pressure of the test substance was determined to be 0.0328 Pa at 20°C (Brekelmans, 2010a).
Reference
The logarithm of the evaporation rate of the reference control substance at 20°C deviated < 10% from the average value obtained during the validation test. This show the acceptability of the data of the reference substances for the determination of the vapour pressure of the test substance.
The equation of reference regression curve was found to be log P20= 1.04 X log V20+ 4.32 (r =0.993, n=10).
Extrapolation of the curve to 20°C resulted in a value of -5.60 for the log νT, 20 of the test substance and the value was fitting in the regression curve.

Description of key information
A study was conducted to determine the vapour pressure of the test substance according to the OECD Guideline 104 and EU Method A.4.
Key value for chemical safety assessment
- Vapour pressure:
- 0.033 Pa
- at the temperature of:
- 20 °C
Additional information
Vapour pressures of the test substance and other category members are as follows:
Oils, vegetable, deodoriser distillates = 0.0328 Pa
Glycerides, C16-18 and C18-unsatd., deodorizer distillates = 0.00113 Pa
Lauric fats deodorizer distillates = 0.152 Pa
Soybean oil, deodorizer distillates = 0.00312 Pa
The VP of 0.0328 Pa was selected for chemical safety assessment as this value was experimentally determined with the representative substance tested. The vapour pressure of other category members have been provided as a weight of evidence to support the experimental value.
