Key value for chemical safety assessment

Additional information

 Based on the chemical structure surface activity is not expected.

Surface tension of 1-octene (CAS 111-66-0) is 21.76 mN/m at 25°C. Based on the molecular structure, it can be concluded that the surface tension of 1,7-octadiene will be less than 33 mN/m at 25°C, which is a cut off value that shall be considered for aspiration toxicity classification according to Directive 67/548/EEC.
