Specific details on test material used for the study:
Name: FAT 40549/A
Surface tension:
51.9 mN/m
Temp.:
20 °C
Conc.:
1.1 g/L
Conclusions:
Surface tension was determined to be 51.9 mN/m at 20 degree C (1.1 g/L aqueous solution)
Executive summary:

In a guideline test based on EEC directive 92/69, A5 "Surface tension" (1992) and OECD guideline no. 115 "Surface tension of aqueous solutions" (1981), the surface tension was determined using ring method.

The experiment was carried out using a tensionmeter (model K8, Krüss GmbH, Hamburg, Germany). The measuring body is a platinum-iridium ring with a wire radius of 0.185 mm and a ring radius of 9.545 mm. The measurements were performed at room temperature.

Based on the findings of the study, the surface tension was determined to be 51.9 mN/m at 20 degree C (1.1 g/L aqueous solution)
