Description of key information

The surface tension of a 1.1 g/L solution of DEIPA was determined as 61.2 mN/m at 20.3oC. The test item is considered not to be surface-active (Butler, 2012). 

Key value for chemical safety assessment

Surface tension:
6.12
in mN/m at 20°C and concentration in mg/L:
1 100

Additional information

Using the ring method, equivalent to OECD guideline 115 and in compliance with GLP, the surface tension of a 1.1 g/L solution of DEIPA was determined to be 61.2 m/Nm at 20.3 oC. The test item is considered not to be surface-active (Butler, 2012).
