Key result
Surface tension:
36.67 mN/m
Temp.:
25.3 °C
Conc.:
2 002 mg/L
Conclusions:
The surface tension of Fatty acids, C18 unsatd., mono and diester with triethanolamine , di-Me sulfate-quaternized was determined to be 36.67 mN/m using an KRÜSS tensiometer at a concentration of 2002 mg/L in a study similar to OECD Guideline 115.

Description of key information

The surface tension of Fatty acids, C18 unsatd., mono and diester with triethanolamine , di-Me sulfate-quaternized was determined to be 36.67 mN/m using an KRÜSS tensiometer at a concentration of 2002 mg/L in a study similar to OECD Guideline 115.

The test item has to be regarded as surface active as the determined surface tension is < 60 mN/m (EC method A5, chapter 3.2). 

Key value for chemical safety assessment

Surface tension:
36.67
in mN/m at 20°C and concentration in mg/L:
2 002
