Description of key information

Surface tension =41.8 mN/m at 20°C in a 1 g/L aqeueous solution.

Key value for chemical safety assessment

Additional information

The data are read across from partially unsaturated TEA-Esterquat which has an almost identical structure. The surface tension of partially unsaturated TEA-Esterquat was examined in a study conducted according to OECD Guideline 115 and EU-Method A.5 (ring method).The mean surface tension of an aqueous solution of 1 g/L partially unsaturated TEA-Esterquat was determined at 41.8 mN/m at 20°C. Because the test item shows a surface tension lower than 60 mN/m, the test item has surface active properties.
