Conclusions:
The surface tension of amides, C8 -18 and C18 -unsatd., N,N-bis(hydroxyethyl) was determined to be 27.7 mN/m at 24.5 ºC.
Executive summary:

According to the OECD Guideline 115 methoid, the surface tension of amides, C8-18 and C18-unsatd., N,N-bis(hydroxyethyl) was determined to be 27.7 mN/m at 24.5 ºC and 0.8475 mg/mL of the sample concentration.

Description of key information

The surface tension was determined using the plate method according to OECD Guideline 115 (Carrillo, 2009).

Key value for chemical safety assessment
