not surface active

Key value for chemical safety assessment

Additional information

Based on the chemical structure surface activity is not expected.

The experimental data for the two components of the substance, ethanol and 2-methylpropan-1-ol support the data waiving. The experimental values for surface tension of ethanol range from 24.5 to 30.2 mN/m and ethanol is not surface active. The experimental value for 2-methylpropan-1-ol is 69.7 mN/m at 20 °C.
