- Key result
- Surface tension:
- >= 72.06 - <= 72.74 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1.43 mg/L
- Conclusions:
- During the specified period of time, no significant changes in the surface tension were detected. Values ranging from 72.06 mN/m to 72.74 mN/m were recorded showing no significant variations. The values of the single determinations show no significant difference (less than 5 % between mean values of the two measurement series)
As the determined surface tension of Petroleum Resins (Kendex 0897) was higher than 60 mN/m, the test item can be classified as not surface active. - Executive summary:
Determination of the surface tension of an aqueous solution of Petroleum Resins (Kendex 0897) according to OECD 115 resp. EU A.5
Findings and Results:
The surface tension of an aqueous solution of Petroleum Resins (Kendex 0897) was determined as 72.52 ± 0.09 mN/m at 20.2 °C. One measurement was performed for verification (after 60 minutes). No significant changes and thus no significant dependence on time was observed.
As these values were higher than 60 mN/m, Petroleum Resins (Kendex 0897) was classified as not surface active.
The surface tension of the negative control lay within the accepted range.The concentration of the test item in the 90% saturated test solution was determined as 1.43 mg test item/L (based on analysis of dissolved organic carbon in the test solution). The saturated solution was obtained from an aqueous solution prepared by shaking 1.00 g/L in water HPLC grade shaking for 72 hours at 20.3 - 23.4 °C in a closed flask at 150 rpm.
