Description of key information

72.1 mN/m at 20.0 °C (saturated aqueous solution)
not surface active

Key value for chemical safety assessment

Additional information

The surface tension of a saturated aqueous solution of diuron was determined by the ring method according to OECD Guideline 115. Because the test item showed a surface tension above 60 mN/m, diuron was regarded to be not surface active.
