test no.	time [min]	measured value [mN/m
1	0	72.4
2	5	72.3
3	10	72.3
4	20	72.3
5	35	72.3
6	65	72.4
7	125	72.3
8	185	72.4
9	215	72.4
10	245	72.3

The measured values showed no time dependence.

Mean value: 72.3 mN/m

Mean value with calibration factor: 72.8 mN/m

The test item is not a surfactant.

Conclusions:

A surface tension value of 72.8 mN/m (c=1.0 g/L, at 20.0 °C) was determined in a reliable study conducted according to EU method A. 5. The test item is not classified as surfactant.

Executive summary:

A surface tension value of 72.8 mN/m (c=1.0 g/L, at 20.0 °C) was determined in a reliable study conducted according to EU method A.5. The test item is not classified as surfactant.
