Executive summary:

The surface tension of the Reaction mass of 2-[2-(benzoyloxy)ethoxy]ethyl benzoate, 1 -[2 -(benzoyloxy)propoxy]propan-2 -yl benzoate, and 2-[2-[2-(benzoyloxy)ethoxy]ethoxy]ethyl benzoate has been found to be 61.1 nN/m at 21.2°C and a concentration of 0.0306 g/L. Therefore, the substance can not be considered to be surface active.

Description of key information

EU Method A.5 (Surface Tension) – Ring Method (Fox J. M. and White D. F., 2010)

Key value for chemical safety assessment

Surface tension:
61.6
in mN/m at 20°C and concentration in mg/L:
0.031

Additional information

The surface tension of the Reaction mass of 2-[2-(benzoyloxy)ethoxy]ethyl benzoate, 1 -[2 -(benzoyloxy)propoxy]propan-2 -yl benzoate, and 2-[2-[2-(benzoyloxy)ethoxy]ethoxy]ethyl benzoate has been found to be 61.1 nN/m at 21.2°C and a concentration of 0.0306 g/L. Therefore, the substance can not be considered to be surface active.

The key value given above has not been determined at 20 °C but at 21.2 °C. However, this subtle distinction is not expected to have a significant impact and the value was therefore inserted above.
