The vapour pressure was measured in the temperature range of 45 °C to 120 °C. The measured vapour pressures at the corresponding temperatures are listed in Table 1. After the measurement no mass loss was determined.

Table 1: Measured vapour pressures and corresponding temperatures

Temperature /°C	Vapour pressure / hPa
45	9.3E-6
50	2.8E-6
55	4.1E-6
65	6.7E-6
75	n.e
120	n.e

n.e.: not evaluable

The detection limit (1x10^-5hPa) was used for the calculation as all measured vapour pressures were below the detection limit.

Table 2: Calculated vapour pressure at 20, 25 and 50 °C

T / °C	p /hPa	p / Pa
20	<4.6E-10	<4.6E-8
25	<8.9E-10	<8.9E-8
50	<1.8E-8	<1.8E-6

This is a conservative estimation of the vapour pressure of the test item for the listed temperatures.

Conclusions:

The vapour pressure of the test item was below the detection limit of 1x10-7 Pa.

Executive summary:

A study was conducted according to OECD TG 104 and Regulation (EC) No 440/2008 method A.4 to determine the vapour pressure of the test item using the effusion method: Knudsen cell. The vapour pressure was measured in the temperature range of 45 °C to 120 °C. After the measurement no mass loss was determined. The vapour pressure of the test item was below the detection limit of 1x10-7 Pa. The vapour pressure of the test item was calculated to be <4.6E-8 Pa at 20 °C, <8.9E-8 Pa at 25 °C and <1.8E-6 Pa at 50 °C, respectively.

Description of key information

Additional information

A study was conducted according to OECD TG 104 and Regulation (EC) No 440/2008 method A.4 to determine the vapour pressure of the test item using the effusion method: Knudsen cell (reference 4.6 -1). The vapour pressure was measured in the temperature range of 45 °C to 120 °C. After the measurement no mass loss was determined. The vapour pressure of the test item was below the detection limit of 1x10-7 Pa. The vapour pressure of the test item was estimated to be <4.6E-8 Pa at 20 °C, <8.9E-8 Pa at 25 °C and <1.8E-6 Pa at 50 °C, respectively.
