Description of key information

The surface tension of a 90% saturated aqueous solution of delta-damascone was determined by using the OECD harmonised ring method according to EU Method A.5 (Huntingdon Life Sciences Ltd., 2008b).

Key value for chemical safety assessment

Surface tension:
61.5
in mN/m at 20°C and concentration in mg/L:
69

Additional information

As the result is greater than 60 mN/m, the test substance should not be considered surface active according to Directive 92/69/EEC (Official Journal L383A, 29/12/1992 p. 113 -235).
