- Temp.:
- 20 °C
- Conc.:
- 1 017.5 mg/L
- Conclusions:
- Under the study conditions, surface tension of the test substance was determined to be 26.3 mN/m at the concentration of 1017.5 mg/L at 20ºC.
- Executive summary:
A study was conducted to determine the surface tension of the test substance, using the ring method according to the OECD Guideline 115 and EU Method A.5, in compliance with GLP. Under the study conditions, surface tension of the test substance was determined to be 26.3 mN/m at the concentration of 1017.5 mg/L at 20ºC. Therefore, the test substance was considered to be surface-active (Hartmann, 2019).

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.
