Description of key information

The mean surface tension of the substance in a 90 % saturated solution was determined from triplicate samples to be 56.7 dynes/cm (mN/m) with a standard deviation of 0.356 dyne/cm (mN/m) at a temperature of 21.7 ºC. Since the surface tension of the substance was found to be less than 60 dyne/cm (mN/m), the substance is considered to be surface-active.
