Description of key information

The surface tension of the substance at 90% of the saturation concentration is in the range 45 – 52 mN/m at 20 °C.

Key value for chemical safety assessment

Additional information

The surface tension of the test item in aqueous solution was determined in a guideline study according to OECD guideline 115 applying the plate method.

The solubility of the test substance in water is less than 1 g/L. In accordance with the guideline and REACH guidance documents the measurement was therefore carried out at 90% of the saturation concentration.

The surface tension of the substance at 90% of the saturation concentration is in the range 45 – 52 mN/m at 20 °C.
