Key result
Surface tension:
ca. 38.1 mN/m
Temp.:
20 °C
Conc.:
1 000 mg/L
Remarks on result:
other: pH: 7.6
Conclusions:
Under study conditions, the surface tension of the test substance, TMAC S, was determined to be 38.1 mN/m at 20°C and pH 7.6 of a 1 g/L solution.
Executive summary:

A study was conducted to determine the surface tension of the test substance, TMAC S (88.3% active) using Du Nouy ring method, according to the OECD Guideline 115. Under the study conditions, the surface tension of the 0.1% the test substance at room temperature (20°C) and pH 7.6 was determined to be 38.1 mN/m (Andersson, 2018).

Description of key information

The surface tension of the test substance was determined using the ring method, according to OECD Guideline 115 (Andersson, 2018).
