ring method
Key result
Surface tension:
49 mN/m
Temp.:
20 °C
Conc.:
10 mg/L

Based on irs surface tension, the test item is considered as possessing surface active properties.

Conclusions:
The surface tension of the test item is 49 mN/m at 10 mg/l and 20°C
Executive summary:

The test item surface tension was performed with the ring method according to recognised guidelines and under GLP. No deviation from the guidelines was observed in the study.

Before measurement of test item surface tension, the apparatus was calibrated with water.

The surface tension of the test item is 49 mN/m at 10 mg/l  and 20°C. Based on this value, the test item is considered as possessing surface active properties.

Description of key information

The surface tension of the test item was determined in a key study of Klimisch validity one, performed according to recognised guideline and under GLP.

Key value for chemical safety assessment

Surface tension:
49
in mN/m at 20°C and concentration in mg/L:
10

Additional information

Based on the test item surface tension at 20°C, it is considered to possess surface active properties.
