Description of key information
The test item had a mean surface tension of 58.6 mN/m. As the surface tension was lower than 60 mN/m, the test item had surface-active properties.
Key value for chemical safety assessment
- Surface tension:
- 58.6
- in mN/m at 20°C and concentration in mg/L:
- 998
Additional information
An aqueous solution of the test item in de-ionized water with a concentration of 998 mg/L was prepared, treated with ultrasound for 5 min and the solution was adapted to the measurement temperature for two hours. After adapting to 20 °C the measurement of the surface tension with the test item was carried out at 20 ±0.5°C (20.1 °C).
The test item had a mean surface tension of 58.6 mN/m. As the surface tension was lower than 60 mN/m, the test item hadsurface-active properties.
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.
