Specific details on test material used for the study:

TEST MATERIAL
- Names (as cited): β,β'-dichloroethyl
- Purity: not specified

Surface tension:

ca. 37.3 mN/m

Temp.:

20 °C

Conclusions:

At 20°C, the surface tension of β,β'-dichloroethyl ether was determined to be 37.3 mN/m.

Executive summary:

The surface tension of β,β'-dichloroethyl ether was measured by the capillary rise method at various temperature ranging from 20° to 100°C. The surface tension of β,β'-dichloroethyl ether decreased linearly with temperature. Surface tension of the substance at temperature t can be given as: y = a -b*t, where a = 40.57, b = 0.1306. At 20°C, the surface tension of β,β'-dichloroethyl ether was determined to be 37.3 mN/m.

The study is described in suffcient details and has been subject to peer-review. The result are judged acceptable and the study has been assigned a reliability score of 2.

Description of key information

The surface tension of Bis(2-chloroethyl) ether was determined to be 37.6 mN/m at 20°C as measured by Sudgen's modification of the maximum bubble pressure method. As the surface tension of Bis(2-chloroethyl) ether is below 60 mN/m, it is considered as surface active according to the cut-off value of 60 mN/m stated in point A.5 of Regulation (EC) No 440/2008 of 30 May 2008 laying down test methods pursuant to Regulation (EC) No 1907/2006 (REACH).

Key value for chemical safety assessment

Surface tension:

37.6

Additional information

In a publication by Mumford & Philips (J. Chem. Soc., 1950, 75-84), the surface tension of Bis(2-chloroethyl) ether was determined to be 37.6 mN/m at 20°C as measured by Sudgen's modification of the maximum bubble pressure method.

The study is described in suffcient details and has been subject to peer-review. The result are judged acceptable and the study has been assigned a reliability score of 2.

In their publication, Gallaugher & Hibbert (J. Am. Chem. Soc.,1937, 59:2521-5). measured the surface tension of β,β'-dichloroethyl ether by the capillary rise method at various temperature ranging from 20° to 100°C. At 20°C, the surface tension of β,β'-dichloroethyl ether was determined to be 37.3 mN/m, which is in good agreement with the data selected as key information.

The study is described in suffcient details and has been subject to peer-review. The result are judged acceptable and the study has been assigned a reliability score of 2.
