Results of Test Item
During the specified period of time, no relevant changes in the surface tension were detected. Values ranging from 37.49 mN/m to 38.49 mN/m were recorded showing no relevant variations. The values of the single determinations show no relevant difference (less than 5 % between mean values of the two measurement series).
Final Result
The surface tension of an aqueous solution of [Trade name] was determined as 37.71 ± 0.19 mN/m at 20.0 °C. One measurement was performed for verification (after 59 minutes). No significant changes and thus no significant dependence on time were observed. As these values were lower than 60 mN/m, [Trade name] was classified as surface active. The surface tension of the negative control lay within the accepted range.
Description of key information
Surface tension is 37.71 + 0.19 mN/m at 20 °C (OECD 115, plate method).
Key value for chemical safety assessment
- Surface tension:
- 37.71
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
