Description of key information

The surface tension of quinoline is 45 mN/m at 20°C. 

Key value for chemical safety assessment

Surface tension:

Additional information

A weight of evidence approach has been developped for surface tension because no valid study is available as primary source.

Values around 45 mN/m were obtained at 20°C. They are consitent with very old literature data (between 1893 and 1917) cited in the publication.

However, it is unknown whether these values were obtained with quinoline as a pure liquid substance or in a mixture with water as determined in the method A5. So it is impossible to conclude if quinoline has surface active properties.
