- Key result
- Surface tension:
- 63.1 mN/m
- Temp.:
- 19.8 °C
- Conc.:
- 90 vol%
- Conclusions:
- The average surface tension of two independent measurements was 63.1 mN/m for a 90 % aqueous solution at 19.8 °C. The substance is considered not surface active.
- Executive summary:
The surface tension of the test substance was determined using the ring method in accordance with OECD TG 115 following GLP principles. The average surface tension of two independent measurements was 63.1 mN/m for a 90% aqueous solution at 19.8 °C. The substance is considered not surface active.

Results
The calibration factor Φb was
determined to be 1.0449 for double distilled water, see Table 1 below.
Table 2 shows the individual measurements for the surface tension of the
aqueous test item solution. From these, the mean and the corrected value
for the given solution were calculated and also shown in Table 2. The
tabulated values represent rounded results obtained from calculation
using the exact raw data. Mean value from both samples: σ = 63.1 mN/m. The
substance is considered not surface active.
