Type of method:
ring method
Surface tension:
ca. 53 mN/m
Temp.:
20.5 °C
Conc.:
0.111 g/L
Remarks on result:
other: The test material is considered to be a surface active material
Conclusions:
The surface tension of a 0.111 g/L solution of test material has been determined to be 53.1 mN/m at 20.5 +/- 0.5°C. The test material is considered to be a surface-active material.
Executive summary:

The aim of this study was to determine the surface tension of the test item, using the european guideline A5 method and ISO 304.

The method used is the ring method.

The surface tension of a 0.111 g/L solution of test material has been determined to be 53.1 mN/m at 20.5 +/- 0.5°C. The test material is considered to be a surface-active material.

Description of key information

In compliance with the european guideline A5 method and ISO 304, the surface tension of a 0.111 g/L solution of test material has been determined to be 53.1 mN/m at 20.5 +/- 0.5°C. The test material is considered to be a surface-active material.
