- Executive summary:
The surface tension of C14 -16 AO has been determined to be in the range 31.6 -31.8 mN/m at a concentration of 0.987 g/L at 21.5 +/-0.5 °C using a ring method designed to be compatible with Method A5 Surface Tension of Commission Regulation (EC) No 440/2008 and OECD TG 115. The substance is considered to be surface-active.
