Data extracted by the Registrant from the graphical plot for o-cyanophenol (Figure 1) in the original report.
The calibration factor Φbwas determined to be 1.0318 for double distilled water.
The table below 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. The tabulated values represent rounded results obtained from calculation using the exact raw data.

Description of key information
69.9 mN/m, 20°C, 1.005g/L, OECD 115, ring method, Weissenfeld 2010
71.2 mN/m, 20°C, 1g/L, Siwek 1971
Key value for chemical safety assessment
- Surface tension:
- 69.9
- in mN/m at 20°C and concentration in mg/L:
- 1 005
Additional information
Inspection of the molecular structure indicated no structural alerts associated with surface activity. A distinct hydrophilic head-group and hydrophobic tail are not present in the molecule and surface activity is thus not expected. However, data from Siwek (1971) demonstrated that surface activity was present at higher concentrations. A guideline study gave similar results at a concentration of 1g/L and is the value carried forward for risk assessment, classification and labeling. The surface tension for a 1 g/L solution was >60 mN/m at 20°C, and hence does not meet the criteria for surface activity according to Regulation (EC) No. 440/2008, A5.
